A slight risk of severe storms exists over all of the WBKO viewing area Thursday. A greater “moderate” threat exists for far western Kentucky, Southern Illinois, the Missouri bootheel, west Tennessee, NW Mississippi and much of Arkansas.

NOWCAST THROUGH LATE MORNING:
A fair sky to start with increasing clouds and winds later.
6am: Mainly Clear 49°
8am: Partly Sunny 55°
10am: Partly Sunny 64°

STILL WARM BUT TURNING UNSETTLED:
Our April Fools Day Tuesday gave us our warmest temperatures of the year so far, soaring into the upper 70s to near 80 with loads of sun and breezy southwest winds! We’ll stay warm through the end of the work week but things are about to turn wetter, and at times, stormy. A warm front pushing slowly northward over the region today may touch off a few widely scattered showers and thunderstorms. Rain chances increase late tonight into Thursday as more disturbances ride eastward into the area. Rainfall could be heavy at times under some of the stronger storms, with small hail possible. Highs today and Thursday will reach the 70s with mild overnight lows only around 60.

As low pressure and a trailing cold front advance through South-Central Kentucky early Friday, there will be potential for some storms to be strong to severe late Thursday night into early Friday morning. A SLIGHT RISK for storms containing gusty winds and large hail is up for much of the region during that period. We’ll dry out Friday afternoon, with highs around 70 to close out the work week.

COOLER WEEKEND:
At this time, Saturday and Sunday look dry but cooler. Highs will be in the lower 60s with overnight lows in the lower 40s.

MORE RAIN:
Another storm system moving northeastward out of the Deep South may send more rain back into the region Monday. Highs remain in the lower 60s early next week.

NOWCAST THROUGH LATE MORNING:
Mostly cloudy to start with a chance of sprinkles.
6am: Partly Cloudy 56°
8am: Mostly Sunny 56°

NO FOOLIN':
The March that came in like a lion with a big winter storm on the 2nd & 3rd went out like a lamb with lots of sunshine and highs in the 70s yesterday. Our April Fools’ Day looks even warmer under a mix of sun and clouds after some morning sprinkles. Highs should reach the mid 70s to make for one of our warmest days of the year so far! Skies remain partly cloudy Tuesday night, with lows in the lower 50s.

APRIL SHOWERS:
Our next storm system moves into the region late Wednesday bringing only scattered showers at first. But by Thursday, periods of rain and thunderstorms are likely. Some heavy downpours are possible. Highs will be in the low to mid 70s until a cold front passes through on Friday morning which will bring an end to the rain and usher in cooler temperatures.

THE WEEKEND:
At this time, Saturday and Sunday look dry but cooler. Highs will be in the lower 60s with overnight lows in the lower 40s. A slight chance for showers returns Monday.

From Cold and Snowy to Warm and Stormy

Posted on Updated on

Southern Kentucky now included in a slight risk for severe storms Friday afternoon and evening.  The primary threats will be the potential for damaging winds and large hail.
Southern Kentucky now included in a slight risk for severe storms Friday afternoon and evening. The primary threats will be the potential for damaging winds and large hail.

NOWCAST THROUGH LATE MORNING:
Mainly clear and very cold.
6am: Clear 24°
8am: Sunny 27°
10am: Sunny 32°

STILL CHILLY:
We may be almost a week into Spring but Tuesday felt wintry with blustery conditions, unseasonably cold temperatures, and occasional snow showers. Clearing skies overnight will set us up for a very cold morning. Today will remain chilly but at least we’ll see lots of sunshine and winds will be much lighter. Highs will reach the upper 40s with increasing clouds late tonight – lows will drop into the lower 30s.

WARMER BUT WETTER:
Temperatures more typical of early Spring return by Thursday and Friday but so does some rain. A frontal system draws closer to us Thursday night spreading numerous showers and a few thunderstorms into the region. As the cold front passes through Friday evening, there is a risk a few of the storms could become severe with the potential for damaging winds and large hail. Highs climb back to near 60 Thursday and into the upper 60s Friday.

DRYING OUT:
It now appears we may have to contend with rain into much of our Saturday before we dry out late Saturday into Sunday. Highs climb from near 60 Saturday into the upper 60s to close out the weekend. We may finally see 70s once again Monday before a weak system delivers a chance for rain and a small cool down into Tuesday.

TODAY:
Mostly Sunny, Not as Cold…High 47, winds SE-5

TONIGHT:
Increasing Clouds…Low 32, winds S-5

THURSDAY:
Breezy & Warmer, Chance of Aft’n Showers…High 60, winds SW-20
Rain Chance 20% – Rain Amount 0.03″

Damaging Wind and Tornado Threat Today

Posted on Updated on

The risk for severe storms continues today for all of Kentucky with the primary threat being the potential for damaging straight-line winds.  While there is a small tornado threat, a few brief spin-ups are possible along the leading edge of storms expected this evening.

SLIGHT RISK OF SEVERE STORMS FOR ENTIRE WBKO VIEWING AREA LATE TODAY AND TONIGHT

EARLY MORNING NOWCAST:
Isolated to widely scattered showers and thunderstorms are possible along with breezy southwest winds.
6am: Cloudy, Isolated Showers 59°
8am: Cloudy, Scattered Showers 62°
10am: Cloudy, Scattered Showers 65°

A WINDY, STORMY THURSDAY:
Today’s weather will be VERY active to say the least. We expect multiple rounds of showers and thunderstorms to affect the area. The first round of scattered showers with a few rumbles of thunder comes this morning with a warm front passing through. Severe storms are not expected with this first round. As the day progresses, expect mostly cloudy, windy, and warm conditions. Afternoon temperatures may flirt with record territory in the low to mid 70s! But that daytime heating may result in a more unstable atmosphere when the second round of storms arrives later today.

A powerful cold front will sweep through the region this evening. Expect an organized line of storms to develop ahead of it. Some of the storms within the line will be capable of producing locally damaging winds of 60-70 mph. Torrential downpours are also likely, and isolated tornadoes cannot be ruled out. The main threat for severe weather comes between 3-6pm for locations west of I-65, around 6-7pm for Bowling Green and along I-65, and between 7-10pm for areas east of the interstate. Be aware of rapidly changing conditions, especially late afternoon into early evening. Stay connected to WBKO, WBKO.com and the WBKO app as we track this powerful system.

QUIETING DOWN:
We dry out Friday, with temperatures remaining mild through the early part of the weekend. A cold front eases through Sunday morning, sending temperatures down to more seasonal levels to close out the weekend.

WINTER NOT OVER YET:
Much colder air returns early next week, with below normal temperatures through the period. There is a slight chance for rain or snow Tuesday morning.

TODAY:
Windy & Warm. Strong Late Day Storms…High 75, winds S 24-44mph
Precip Chance: 90% – Amount: 0.50″

TONIGHT:
Breezy with Strong Thunderstorms…Low 37, winds W-18
Precip Chance: 100% – Amount: 0.75″

FRIDAY:
Sunny and Cooler…High 54, winds SW-12

SLIGHT RISK OF SEVERE STORMS FOR ENTIRE WBKO VIEWING AREA LATE THURSDAY INTO THURSDAY NIGHT

EARLY MORNING NOWCAST:
Showers and thunderstorms will move out of the viewing area followed by clearing west to east.
6am: Clearing 51°
8am: Mostly Sunny 50°
10am: Mostly Sunny 52°

STORMS END, SUN RETURNS:
It’s been a while but many of us were awakened by the sound of thunder early this morning. A weak disturbance moved through bringing some Spring-like thunderstorms which are now moving away. We’ll dry out this morning with a mix of sun and clouds expected today. We stay warm, with highs near 60.

STRONG STORMS THURSDAY:
Our next system arrives Thursday, and it looks quite potent. It will be packing plenty of wind/jet stream energy along with abundant moisture. Multiple rounds of showers and thunderstorms are likely with this system. The first round is expected early in the day, with the second (and stronger) round coming late in the day. At this time, it appears an organized line of storms will march through the entire area between 3pm-9pm Thursday. Some storms within that line may be capable of producing locally damaging winds, with isolated tornadoes and hail also possible. It will be a very windy, warm day, with near record high temperatures in the low to mid 70s before the cold front arrives in the evening. Stay connected to WBKO and wbko.com as we track this powerful system.

QUIETING DOWN:
We dry out Friday, with temperatures remaining mild through the early part of the weekend. By early next week, colder readings make a comeback, with a chance for rain or snow showing up Tuesday.

TODAY:
Partly Sunny, Continued Warm… High 61, winds SE-6

TONIGHT:
Cloudy & Breezy, Thunderstorms After Midnight…Low 48, winds S-13
Precip Chance: 30% – Amount: 0.10″

THURSDAY:
AM Storms, then Breezy with Strong Late Day Storms…High 75, S-24
Precip Chance: 80% – Amount: 0.50″

Flood Watch, Severe Weather Threat for the Weekend

Posted on Updated on

Dec20radar

A look at radar at 8:14 this morning shows scattered showers with brief downpours occurring.  Much of the activity is moving east of I-65.  So far, no thunderstorms have been detected.  Our day is starting windy and warm with temperatures in the 50s.

Dec20fri10am

The morning Futurecast map for 10am shows scattered showers will continue today with maybe a few brief downpours but nothing serious.  Of course, the winds will continue to kick up from the south and southwest at 15-25, even 30 mph at times.

Dec20fri10pm

The Futurecast map for 10pm tonight shows a tapering off of some of the scattered shower activity while heavier rains and thunderstorms ramp up to our west.  We will begin to see heavier rain pick up for a time tonight – especially west of I-65.  No severe storms are forecast tonight, just general rumbles of thunder with the possibility of some drenching downpours.

Dec20watches

Overnight is when we will begin to see many of the Flood Watches and Advisories go up “officially” and as you can see, they are pretty widespread.  There is a warm and a cold side to this massive storm system and we will stay on the warm side of things for the duration of the weekend.  While the Flood Watch takes up only the western third of the WBKO viewing area as of this writing, it could be further extended east as we go through the day.  Further north and northwest (the cold side), there are numerous Winter Weather Advisories and Winter Storm Watches.  If you’re planning to travel north or west of St. Louis, look for snow and ice to become a major issue throughout the weekend.

Dec20sat10am

Saturday begins with a line of intense rain and strong thunderstorms just to our west as a second impulse of low pressure rides along a stalled frontal boundary.  That slow movement will lead to drenching downpours and torrential rains mainly west of I-65 for the first half of Saturday.  Some of you east of I-65 and along the Cumberland Plateau may not even see that much rain for the first part of the day.  In fact, if enough sun energy bleeds through the clouds, this will cause a rise in instability which may lead to stronger storms later in the day.  Therefore…

Dec20svr

…the Storm Prediction Center has placed ALL of the WBKO viewing area (and beyond) under a SLIGHT RISK for severe storms Saturday afternoon and evening.  While the primary threat area looks to be west of I-65, that added instability I just mentioned will slowly move east into Saturday evening putting all of our viewers under the threat for potentially damaging winds, flooding rains and even a few brief, short-lived tornado “spin-ups” as we have seen before with these kind of systems.  It will be in the form of a quasi-linear “line” of storms that can bow out at certain points causing a tornado or two.  However, the overall tornado threat is not very high and much of that depends on any sun we get on Saturday.

Dec20qpf

As we have discussed here, on TV and my podcast over the last few days, rainfall is going to be the biggest impact from this system for Southern Kentucky.  Again, the rainfall forecast map shows that we are in a “split” between very heavy rain to the west of I-65 with lighter amounts to the east.  With the slow propagation of the cold front, this will cause creeks, streams and rivers to rise above bank full to the west with amounts of 3-4″ while 2-3″ rains are certainly possible in and around the Bowling Green area Saturday into Sunday.  Low water fords and some back roads will certainly become flooded over the weekend and even into early next week.

Dec20sat10pm

By Saturday night, the second impulse of low pressure will be passing to our north and the stalled front will begin to move eastward…slowly.  Some of the heaviest rain for those along and east of I-65 will take place then begin to subside early Sunday.  Colder air will move in as well dropping our temperatures by Sunday afternoon into the 40s, then into the 30s but the best moisture will be gone by the time the cold air arrives…therefore, we are not looking for any winter weather with this system here in Southern Kentucky.

Dec20icast

The long range forecast still calls for a quiet but “snow free” Christmas here.  Highs will be in the mid 30s Christmas Eve but will warm into the upper 40s by Christmas Day.  Some rain will move in for Thursday.

We will do our best to keep you up to date on the weather situation throughout the weekend.  Just download our WBKO app from the App Store or Google Play and you will see radar and the latest forecasts.  Stephanie Midgett will be here with any live updates if they become necessary.  Be sure and have your NOAA weather radio turned on just in case warnings are issued.  If you’re leaving out of town for the holiday, have a blessed Christmas time with your family and friends, drive safe and KTWBIKY!

 

Heavy Rain, Flooding Becoming A Concern

Posted on Updated on

Dec18temps

Temperatures are starting out rather chilly this morning – in the 20s under a clear sky across the region.  You will find some frost on your windshield so allow some time to warm up you and your vehicle.

Dec18ridge

NO WEATHER IMPACT OF SIGNIFICANCE TODAY

A sprawling ridge of high pressure dominates our weather today with the center of it practically sitting right on top of Southern Kentucky/Middle Tennessee.  The high pressure center will begin to move east today allowing for a more southerly wind flow starting tonight and especially on Thursday.  In the meantime, expect a very nice day today with lots of sunshine and seasonable temperatures around 50° (average high for today 47°).

Dec18moisture

THURSDAY’S WEATHER IMPACT: BREEZY WINDS AT 10-20 MPH

We will see a warm and breezy day Thursday as the difference between the strong ridge of high pressure interacts with the deepening cold front to our west.  That pressure difference will cause our winds to pick up from the south and southwest at 10-20 mph with some higher gusts expected Thursday afternoon and evening.  This will also allow the Gulf of Mexico to open up with an abundant moisture feed starting late Thursday night.  We will begin to see rain moving into the region early Friday.  Mainly, scattered showers will develop over Southern Kentucky/Middle Tennessee as a slow moving cold front approaches.  High temperatures in the coming days will run way above average in the 60s!

Dec18qpf

WEEKEND WEATHER IMPACT #1: HEAVY RAINS, FLOODED STREAMS/CREEKS/RIVERS

As mentioned here in previous posts, our area looks to see a washout for the upcoming weekend.  Several rounds of potentially heavy rain will occur from Friday through early Sunday.  The current rainfall forecast (above graphic) shows the potential for 2-3″ of total rainfall with higher amounts along and north of the Ohio River where a melting snowpack will make runoff a problem.

Dec18spc

WEEKEND WEATHER IMPACT #2:  POTENTIAL FOR STRONG THUNDERSTORMS

The SPC (Storm Prediction Center) is picking up on what we discussed here previously…the possibility of some strong to severe storms on Saturday.  While the current risk area does not include the immediate South Central Kentucky area, we could see enough instability for a few stronger storms.  We’re not talking about a widespread tornado threat here but a few storms may reach severe limits.  However, the biggest threat we will see this weekend is again from the potential for flooding.

Dec18icast

As you can see from our long range forecast, all the nasty weather should be out of here in plenty of time for the Christmas holiday.  Both Christmas Eve and Christmas Day look mainly sunny with high temperatures in the 40s and lows in the 20s.
