Changes come for the end of the weekendMarch 15th, 2014 at 10:52 pm by wthijosephdames under Weather
A shift in conditions for Sunday as a Low Pressure System travels in for the afternoon. Sunny and comfortable temperatures will flip-flop with cloudy and cooler temperatures for the day (Lower 30s). As of tonight that moisture is just to the west of Illinois and is tracking eastward with the Wabash Valley in the pathway.
More clouds will develop with colder air spilling in by the time we reach our afternoon. Snow and rain are in the books for our Sunday, but the more and more I look at the updated models, the less and less chance of snow I see arising. Part of that is due to the tracking of the system, but also to do with a high pressure sliding in from the north which will help push that precipitation south and dry things up slightly.
I haven’t completely eliminated the chance for snow though for our Sunday. The southern region of the Wabash Valley has a greater chance for snow, it will be light snowfall accumulation or up to an inch possible. Temperatures will definitely drop though for your Sunday and rebounding into the 40s for St. Patrick’s Day.
