Wisconsin Weather Update for February 18, 2013.

By: HaleStorm , 1:43 PM GMT on February 18, 2013

Light rain this afternoon, changing to light snow this evening, ending tomorrow morning. Windy and colder tomorrow. Bigger snow Thursday night and Friday.
A low pressure system currently in Kansas is going to quickly move northeastward with the jet stream, developing precipitation across Wisconsin later today. Warmer temps with the southerly wind means that the precip this afternoon will likely start out as rain before changing over to light snow around sunset.

Behind today’s cold front, temperatures are going to plummet into the teens tonight and not get above 20 again until probably Thursday. But with Thursday comes a new panhandle hook low pressure system and the threat of a larger snowstorm which could definitely impact travel Thursday night and into Friday. Another big precip-maker may arrive next week Monday and Tuesday, but you’ll have to wait until next week to see how Bryce illustrates that one.
