Good afternoon, everyone.It’s a gorgeous day in the bluegrass state and that nice weather will roll over into the first part of Monday. The second half of Monday will feature an arctic front slamming in, bringing frigid temps and the first snowfall of the season for many.
Here are some updated thoughts:
- The late arriving front means temps are mild for the daylight hours on Monday. Once the front blows in, temps drop some 20-30 degrees in a few hours.
- Highs Monday may reach the low 60s and then be roughly 40 degrees colder by Tuesday morning with upper teens and low 20s.
- Rain develops along and ahead of the front, then quickly transitions to snow behind it. That’s where the bulk of the precipitation will be.
- A decent band of light to moderate snow will be noted as it works from northwest to southeast across the state.
- As our wave of low pressure develops, there is likely to be an enhancement of the snow across southeastern Kentucky late Monday night and early Tuesday morning.
- The northwest wind coming down the length of Lake Michigan is aimed at central and eastern Kentucky into Tuesday, keeping flurries and snow showers going.
- Snowfall accumulation is likely across the entire region. Coatings to 2″ look good, especially on grassy and elevated surfaces. We will have to watch southeastern Kentucky for the possibility of locally higher amounts showing up.
- I will have a First Call For Snowfall map out later this evening.
- Given the rapid temp drop, slick spots will likely develop on area roads Monday night and Tuesday. This may bring a few delays or cancellations.
- Temps are frigid and wind chills will be crazy for this early in the year. Record lows will be possible Wednesday.
The models continue to be in pretty good agreement with one another.
The NAM is the wimpiest with the snow numbers, but one of the biases is for the model to be too dry with systems moving in from the northwest. That’s usually the case with any kind of precip. Here’s the NAM…
One trend on all models from above is for the general coating to 2″ snow potential. The other is for the potential for a little more than that across the southeast.
Temps are going to be brutal for early November. Here are the lows for Tuesday morning…
I will have another update later today. See ya then and take care.
