Mainly clear this morning with a few areas of patchy fog. Temperatures will start in the upper 40s to low 50s, rising to near 68° around 10am and near 75° by noon under a sunny sky.
MAJOR MIDWEEK WARMUP:
We dried out Monday, with gradual late-day clearing resulting in more sunshine. Temperatures will warm up quite a bit today and Wednesday. Look for afternoon highs to return to the lower 80s as we close out April and open up the month of May. Overnight lows will be mild under fair skies the next two nights.
COOLER AND UNSETTLED (AGAIN!):
A storm system approaching from the Plains Thursday will send moisture back to South-Central KY for the end of the week. There’s a good chance for showers and thunderstorms Thursday and Friday. Daytime highs will backslide into the 70s Thursday and into the 60s with more clouds/rain around Friday. Rainfall coverage over the weekend will be greatly dependent on where a cutoff area of low pressure sets up. At this time, it still appears unsettled for Derby Day (Saturday) and Sunday, with highs in the 60s.
Sunny & Warm… High 81, winds SE-5
Clear & Mild…Low 57, winds Calm
Mostly Sunny & Warm… High 83, winds SE-6
Showers will gradually end from west to east this morning.
RAIN MOVES ON…
An area of low pressure along the Gulf Coast and a cold front to our west brought beneficial rains to the region yesterday. The rains taper off from west to east this morning with some sun returning for most areas by late afternoon. It will be breezy and cool, with temperatures struggling to crack 70° which is over 10° below mid-September averages.
…COOLER AIR MOVES IN:
Real Autumn-like weather settles in for midweek, with some of the chilliest overnight readings we’ve seen since April expected for the next two nights! Many areas will likely wake up to lows in the low 40s Wednesday morning and again Thursday morning. Canadian high pressure will bring us lots of sunshine those days, and while highs may barely make it out of the upper 60s Wednesday, temperatures should moderate some late in the week.
BRIEF WARMUP, THEN MORE COOL AIR:
Southwest winds and early day sunshine Friday will send readings back to near seasonal averages for a short while. However, a cold front moving through late Friday night into Saturday morning will bring with it a chance for scattered showers followed by another big cool down. Highs drop from the low 80s Friday back into the low 70s for the weekend. Overnight readings will fall from the 50s back into the 40s.
Breezy with Rain Ending, Clearing Later…High 70, winds NW-14
Clear and Cool with Patchy Fog…Low 42, winds Calm
Sunny and Pleasantly Cool…High 70, winds NE-6
Mainly cloudy with areas of patchy drizzle and fog along and east of I-65 while some clearing takes places further west.
ISAAC MOVES AWAY:
The remnant low – which at one time was Isaac – finally moves away from our area today. With some moisture still left in its wake, there may still be a few showers possible this afternoon – mainly east of I-65 with high temperatures in the mid to upper 80s as more sun works back into the region. There will be another shower chance late Wednesday afternoon as a weak front crosses the area.
AN UNSETTLED WEEKEND:
Thursday will be dry, warm and partly sunny as temperatures return to the low 90s. However, another weather maker looks to arrive late Friday night bringing scattered rain and thunderstorms. Mostly cloudy Saturday with scattered thunderstorms and highs in the low 80s. We’re looking at a nice cooldown by Sunday as daytime highs fall back into the low to mid 70s.
Partly Sunny, Isolated Showers…High 87, winds NW-3
Precip Ch. 20% – Rain Amount .05″
Partly Cloudy, Areas of Patchy Fog…Low 70, winds Calm
Partly Sunny, Chance of Showers…High 90, winds W-3
Precip Ch. 30% – Rain Amount .10″
Mainly clear this morning but there will be areas of patchy dense fog. Drive carefully!
DRYING OUT (AND WARMING UP):
We will see a few areas of patchy dense fog this morning thanks to a cool, wet ground and overrunning warmer air moving in. Expect plenty of sunshine to return today allowing for afternoon readings to jump to near 80°. On Wednesday, a weak cold front moves through the region late in the day. This could spark off a few widely scattered thundershowers, but the majority of us look to remain dry. Sunshine and warmth resumes for Thursday and Friday, with highs in the low to mid 80s and seasonably mild overnight lows.
It looks as if a Summerlike weekend is shaping up for us! We’re expected fair to partly cloudy skies with highs in the mid 80s both days. Our next decent shot at rain shows up Monday.
Mostly Sunny and Warmer…High 80, winds N-6
Mainly Clear and Mild…Low 56, winds Calm
Partly Sunny, Chance of Afternoon T/Storms…High 82, winds NW-7
Precip Chance 20% – Rain Amount .10″
Mainly clear to partly cloudy skies this morning with a few areas of patchy fog.
WORK WEEK ENDS QUIETLY:
We’ll see some sunshine return today thanks to high pressure. There will be a few clouds mixing with the sun at times. Afternoon highs should top out in the mid 50s – just a little above seasonal averages. We stay dry tonight with lows in the 30s.
A WINTRY WEEKEND?:
All eyes will be on a low pressure system developing over Southeast Texas late Friday and moving into the Deep South Saturday into early Sunday. This system is likely to spread moisture into our area, with rain breaking out first Saturday evening which may change over to snow late Saturday night into Sunday morning. The exact track of the low is uncertain and temperatures will be very marginal…both of which make forecasting snow amounts very difficult at this time. However, it’s possible that significant accumulations of snow could occur before the system moves out Sunday afternoon. Stay tuned to WBKO and WBKO.com for the latest as we track this potential winter storm for the weekend.
EARLY NEXT WEEK:
We’ll warm back up early next week with 50s returning by Tuesday. Chances for rain showers are in the forecast late Tuesday through Thursday.
Partly Sunny and Mild…High 55, winds NE-5
Increasing Clouds…Low 35, winds Calm
Mostly Cloudy, Evening Rain…High 53, Low 32, winds NE-6
Precip Chance 80% – Rain Amount .35″
Snow Likely…High 37, Low 25, winds NE-9
Precip Chance 50% – Around 1-2″ total snow accumulation
The winds are picking up as an area of low pressure and cold front approaches the region.
Already, wind gusts of 30-40 mph have been reported across Southern Kentucky with sustained winds of 15-25 mph.
The gusty winds could become a quick hazard if you’re out at area lakes or driving a high-profile vehicle.
At least the winds are warm as temperatures have soared into the mid and upper 50s and may rise to the low 60s this afternoon. Once a weak cold front passes through this evening, temperatures will cool back down into the upper 30s to low 40s tonight and return to the 50s tomorrow.
The weather looks fine for New Year’s festivities Saturday, Saturday night and Sunday morning.
The really cold air arrives Sunday night as a more powerful cold front arrives with deep Arctic air. Monday’s highs will only reach the mid 30s but dip into the upper teens Monday night!
Happy New Year!
This time of year, we keep a sharp eye on the red line.
The “red” or pinkish looking line in the graphic above is called “the 540 line”. Those of us in weather pay attention to this line because it’s a measurement of air thickness between 1000 and 500 millibars. High thickness of combined temperature and moisture in this area would produce an atmosphere too warm for snow. Low thickness (540mb or lower) means the air is “thin” enough for snow to reach the ground.
Many forecasters also refer to the 540 line as “the rain/snow line” but it also acts a good indicator of where very cold air may make its presence known.
As you can see from the map above, the 540 line drops well south into the Tennessee Valley on Monday as a deep low pressure system tightens and strengthens over southern Canada. While we’re not concerned about rain vs. snow, we will be looking at a big surge of cold air beginning Monday and hanging around a day or two.
Longer range models show the Arctic plunge will be short-lived and does not look to produce any snow around Southern Kentucky.
So, we leave the old year warm…and ring in the new year freezing!
While some areas to our north picked up some measurable snow, we’ve only seen a few flakes in Southern Kentucky.
Drier air behind a low pressure system is working in much faster than the computer forecast models had anticipated. This is cutting off the moisture supply as much colder air arrives. However, places such as Carbondale, IL picked up 1.5″ of snow this morning and Indianapolis, IN saw 2-inches.
If you happen to see snow showers this afternoon and evening, don’t expect much. While snowflakes may fly around with the blustry northwest winds of 15-30 mph, this is not the kind of Winter storm system that would bring us accumulating snow or produce travel problems.
Skies will begin to clear this evening as high pressure returns. Sunshine will make a comeback for Wednesday and for the rest of 2011. In fact, we’re looking at a gradual warming trend the next few days with daytime highs rising into the mid and upper 50s.
With the additional rainfall this morning, Bowling Green reached a new plateau for year-to-date precipitation. As of 7am this morning, we’ve measured 62.92″ of precipitation for the year 2011 making it now the 5th wettest year on record for Bowling Green. All it would take is another 0.31″ of precipitation to get us to the next benchmark of 63.23″ which would put us equal to the 4th wettest year on record which was 1989.
Occasional light to moderate rain continues across Southern Kentucky. Watch for ponding water on area roadways.
RAIN TO SNOW…BUT HOW MUCH?
Overnight, rainfall amounts have ranged from .25 to .50″ with some locations picking up an additional .75″. As an area of low pressure moves through the region today the rain may mix with or change to a period of wet, slushy snow. However, snow accumulations are not expected except for a few grassy areas and less traveled roads mainly north and northwest of Bowling Green. Winds will be quite breezy today from the northwest at 15-30 mph.
FINAL DAYS OF 2011…
Wednesday will be partly sunny and cool with daytime highs in the lower 40s. Through the rest of the week, temperatures will slowly warm before reaching the upper 50s by Friday. Overnight temperatures will be in the upper 20s and the lower 30s for the second half of the week.
THE NEW YEAR BRINGS…
Rain for January 1st with highs in the low 50s. A cold front will pass through Sunday night bringing a cooler Monday with highs in the mid 40s.
Rainy, Breezy, Afternoon Rain/Snow Mix…High 43, winds NW-15
Precip Chance 100% – Rain Amount .25″ – Snow Amount less than a dusting
Becoming Partly Cloudy…Low 28, winds NW-5
Mostly Sunny…High 42, winds W-6
Midday radar tells the story…rain is headed back this way.
An area of low pressure – currently over Texas – will be moving northeast this evening into the Tennessee Valley bringing us a good chance of rain tonight and through the day Tuesday. Rain chances are at 100% both tonight and Tuesday.
Right now, it appears we should begin to see raindrops in Southern Kentucky sometime after 7pm this evening.
While we will see mostly rain across the area Tuesday, there will be a brief period when colder air is drawn in as the low pressure systems moves across Kentucky. During that time, some of the rain may mix with…or change to a wet snow. However, temperature profiles near ground level indicate it still may be too warm for any accumulation. There could be some slushy accumulation of snow on grassy areas and on some less-traveled roadways by Wednesday morning.
