We started off with a dusting of snow for many areas (officially 0.20" in Louisville) this morning. Next up is a light wintry mix this afternoon and evening. Notice on the 1st map below, temperatures are all well above freezing, so this mix of rain, sleet, and snow should not cause any major impacts. The 2nd map shows the steadier mix this evening, with temps still above freezing.
But, it's January, so let's talk about our next cold air events. We've got a warm-up this weekend, and the next shot of cold air doesn't arrive until next Wednesday. The 3rd map below shows the heart of this cold air well to our northeast, so this cold spell won't be anything like the Arctic blast we had earlier this week.
The 4th map shows the next shot of cold air could be stronger just after Wednesday's cool-down. This strong flow of cold air could arrive next weekend. Notice more of a wrap-around and the deeper cold colors with a strong polar low to our northeast.
The last two maps show the same time frame of maps 3 and 4, but in a different way. The first blue line on these maps is the 540 line, a general starting point for frozen precipitation, if there is any precip. Notice a more forceful push south with the cold air next weekend.
At this time, the 1st shot of cold air on Wednesday will take highs down to the lower 30s, with perhaps some flurries or light snow showers. The following shot of cold air next weekend could bring colder conditions, and it's too early to tell about snowfall.
So, even though we've got a nice warm-up this weekend, don't put away the long underwear just yet!
