Good Saturday and welcome to fall. It officially arrives at 10:49 this morning and mother nature looks ready to jump right into late fall air. A strong cold front is crossing the state today and will usher in some very chilly air for the next few days. This will bring us the first frost threat of the season.
Winds are going to be a big player today as our front blows through. Gusts may approach 40mph at times as the cold air surges in from the northwest. Readings ahead of the front will hit the low 70s before rapidly falling as our boundary passes. By early evening… many temps will already be falling through the 50s.
That will set the stage for thermometers later tonight to hit the upper 30s in many areas. This may give us a touch of frost… especially in the traditional cold spots. Sunday will be sunny, breezy and chilly with highs struggling to get out of the 60-65 degree range across the entire state.
It’s Sunday night that I think readings may really take a nose dive. Most reporting stations will likely come in with mid and upper 30s and the colder valleys may be a few degrees colder than that. I suspect that we may see a few readings approaching the freezing mark across central and eastern Kentucky. Patchy frost (at least) is a real threat Monday morning.
After another chilly day on Monday… our chilly pattern begins to break down as we lose the blocks that have kept it in place lately. You can see that very well on the European Ensembles 500mb Height Anomaly Charts…
All that means we go into a pattern with temps near normal for the rest of next week. Highs return to the 70s and we will throw a daily threat for scattered showers and storms your way starting Tuesday.
Looking farther down the road… Canada may grow pretty cold during the first few weeks of October and we will have to watch for any buckles in the jet stream that would unleash that cold and send it our way.
Have a fantastic Saturday and take care.
