Frost possible by Sunday morning

Good Saturday, everyone. Much colder air continues to push into the region as our powerhouse of a cold front moves east. This is leaving us with the potential for the first frost of the season in many areas by Sunday morning.

Let’s begin with what’s going on out there today. We start things off with leftover clouds and a few showers across the east, with a quick drying trend coming west to east. Here’s regional radar to use early today:

Temps this morning range from the upper 30s north and west, to the 40s east. As skies become mostly sunny today, temps will only be in the 50s for highs. Gusty winds will add a little chill to the air.

For Cats fans heading out to Kroger Field this evening… Bundle up! Temps will mainly be in the 40s.

Clear skies and light winds tonight will allow temps to drop into the low and middle 30s for many. A few of the valleys may even dip below freezing. This would allow, at least, patchy frost to develop. Green thumbs are on alert.

The rest of Sunday looks awesome with highs in the 60s with a mix of sun and clouds. Similar weather will be noted on Monday.

things change quickly on Tuesday. That’s when we get another deep trough to dig in here, picking up a storm system from the south and rolling it up the east coast. This is a winter looking setup:

European

Canadian

No, the end result isn’t winter weather, but the setup is something you typically see in the winter months. Often, the fall storm track can be a precursor to the winter storm track.

The air behind the above storm system will bring another frost/light freeze threat by Thursday morning after a day likely in the 50s on Wednesday.

The setup behind this looks damp as we head into next weekend as another storm system rolls our way. Temps should also warm up as this moist flow develops.

I’ve been talking about a potential really cold blast during the final week or so of October. Granted, the models are still in the fantasy range, but look what showed up:

Enjoy the day and take care.
