A Quick Update

Good rainy Thursday evening. Your friendly weatherdude and the WKYT folks will be walking in the Lexington Christmas Parade this evening, so my time is short. Let’s break it down:

– Showers will increase tonight and will really pick up on Friday. The heaviest rain will fall across the northern and western parts of the state.

– Rounds of showers and some thunder will carry us through the weekend. Locally heavy downpours will be possible.

– A strong cold front swings through here on Monday with a 20-30 degree temp drop in just a few hours. Some of the models are now showing a secondary wave of low pressure developing along this front to our east Monday night. Here’s the European showing this…

Some runs of the GFS lately have been hinting at this similar scenario, but the GFS is back to full waffle mode. The NAM only goes out to 84 hours and that takes us into Sunday night. The latest run shows this secondary low developing…

The UKMET and NOGAPS show something similar taking place. IF this trend does work out, it would certainly up the snow potential later Monday and early Tuesday. For now… I will stick with my rain to snow shower thoughts until the picture clears up a bit.

Enjoy the evening and take care.

Wet Weather Ushers In The Start To Winter

Good Thursday everyone and thanks for making KWC a part of your day. We are entering a very wet pattern over the next several days and that gets the change to winter off and running. The drops will move in later today and continue on and off through the upcoming weekend. Then the bottom falls out.

Light rain will break out this afternoon across southern Kentucky and this will slowly lift northward into the evening hours. This may impact the Lexington Christmas Parade. Your friendly weatherdude will be walking in it, so give me a shout if you’re down there.

Rounds of showers and some thunder will be with us from Thursday night through Sunday. It’s not going to rain the entire time, but some locally heavy rainfall will be possible. This is in response to a stalled out front across the Ohio Valley that features waves of low pressure working along it.

The strongest low sweeps across the region by Sunday night and this will drag a cold front across the state. Temps will drop by nearly 30 degrees in a matter of hours as this front passes. Rain will make the transition to a period of light snow and snow showers during the day. Here’s the timeline from the GFS…

The GFS Ensemble Mean supports the rapid temp drop and light snow/snow shower threat…

No wonder the bottom falls out of the thermometer, check out how deep that trough is…

A few flurries will linger into Tuesday with lows in the low 20s and highs in the 30s.

This is the pattern and time period I’ve been yapping about for the past few weeks. This takes us into the start of winter and the pattern only grows colder and snowier from there. The second half of December has a real chance to be special across much of the country and every medium range model is on board with this.

For fun… watch the deep freeze settle into the country over the next few weeks…

Those are the numbers from one of the latest GFS ensemble runs. You’re seeing the temp departures for those 5 day periods… in celsius. That, my friends, is one cold look.

I will give you another update later… have a great day and take care.
