After today, our weather will be taking a turn for the worse. Not the best way to end up February with rain, snow, and colder temperatures.
Let's start off with big weather-changer and that's the big drop in the jet stream over the eastern US. The jet stream is the river of air, the storm system highway, that covers the globe. When it goes south, it brings in a colder weather pattern. This position of the jet stream will keep colder air moving into Kentuckiana day by day, until highs are only in the 30s this weekend. This jet stream map is Saturday morning, but colder air will already be moving in with snow chances on Wednesday.
Speaking of those snow chances, the next map shows a bunch of green and blue. The blue indicates snow, green is rain. We'll have a mix of snow and rain Wednesday and Thursday, and perhaps more snow than rain on Thursday. Only small accumulations expected from time to time Wednesday through Friday, mainly on grassy, elevated surfaces - since temperatures will mainly be above freezing.
The final map simply shows the cold pattern all the way through the weekend. Notice how the cold air follows the jet stream pattern from the first map. Until we can get the jet stream to move back north, it's going to stay chilly.
So, this first weekend of March coming up is looking cold and mainly dry - perhaps like a cold lamb.
