The deeping low pressure system has now brought widespread rain to to Southern Indiana area. As the low continues to strengthen tonight, expect a drastic change in temperatures to come after midnight. The latest 0Z and 12Z GFS Model Runs are still indicating a dry slot forming just after the passing of the cold front somewhere close to midnight tonight. This dry slot should keep snow accumulations down to a minimum for us. If current predictions in the models hold up, we should get up to one inch of snow tonight and a little more from wrap around moisture on the day Sunday, with lingering snow showers into Monday. It looks like 3" is the absolute maximum we could get with this system unless something drastic changes and it really looks like 1-2" would be much more reasonable at this point. In looking at some other sources of weather info, it looks the the Louisville National Weather Service will be issuing a Winter Weather Advisory later today. Dubois County is the farthest county west in their warning area, so we'll likely be under it and it may be possible that Spencer, Pike and counties to our west will not be since they are in the Paducah NWS office's warning area. Regardless of whether an official Advisory is issued or not, please take caution. This is a potent storm that heeds our attention.
A timeline of what to expect from this system is below:
The cold front will pass somewhere around mindnight-1am tonight, ushering in bitter cold temperatures with it. During the day on Sunday, expect widespread snow showers to form and blustery conditions. Winds will be from the Northwest at 15-25mph sustained, gusting into the 30s! This could create hazardous road conditions if enough snow falls and is blown around. In addition, expect wind chills to be in the single digits to below zero as temperatures steadily fall throughout the day on Sunday as we head to an overnight low of 13. Winds will continue to be sustained in the 20 mph range on Monday as we only rebound to a high of 19 before dropping back to 9 Monday night!
Next week looks to be unseasonably cold, with highs only rebounding to near freezing by Wednesday. Another round of wintry weather could come into play on Thursday, but it does not appear to be as strong a system. I've only forecasted a 30% chance of rain/snow mix at this point. I'll have more on that system as we get closer to Thursday. Here's your updated 7-Day Outlook:
