While the current focus is on whether we will get our first accumulating snow of the season early Monday morning, potentially record breaking cold air is poised to arrive early Tuesday.
For Southern Kentucky and the WBKO viewing area, we will see mostly rain today with a brief changeover to light snow after 4am Monday morning. Much of the viewing area will only see minor snow accumulation with the better chance of an inch or two of snow west and northwest of the Natcher Parkway corridor. This coating of light snow may cause some icy spots for the Monday morning commute.
Monday’s predicted high of 33° will equal the “coldest high maximum” of 33° set in 1951. With a breezy northwest wind, temperatures against your body will feel like its 18° to 25°.
The coldest air of the season will arrive Monday night as a piece of polar energy is shunted southward into the Ohio Valley region. This will cause our temperatures to plummet into the teens early Tuesday morning. Along with this will be a breezy north wind which will produce BELOW ZERO wind chills of -5° to -10°!
Monday night’s predicted low of 16° doesn’t look to break the standing record low of 10° set in 1891 but bitter wind chills will continue in the single digits.
The extreme cold will hang around Tuesday with a forecast high of 25° which is 3° colder than the “coldest high maximum” for that day of 28° set in 1880. Wind chills will be relentlessly frigid in the single digits and teens. Tuesday night’s predicted low of 18° will rival the standing record low of 17° set in 1951.
We will finally see a warming trend (if you want to call it that) starting Wednesday and Thursday as highs reach into the 40’s, even close to 50° by Friday.
Keep in mind, average high temperatures for this time of year are 61° and average lows should be around 38°.
