March 20 Forecast Discussion

This is an image 24 hours out from the 12z GFS.
Low pressure working its way across the eastern Great Lakes will create some showers and storms as it moves through, carrying a punch of warmer air. Convective thunderstorms are possible with this situation.
Warm spell will continue across the Central US including the Plains, Midwest.
Low pressure in the Northwest will keep the warm spell away and also provide for a wet day tomorrow.
Specific concern involves low pressure dropping into Kansas. This low pressure will be the base for a severe weather outbreak that will occur in the Plains to the Midwest in the next 3 days as a squall line, especially into Tuesday. Will definitely have to watch this situation unfold.
Another concern is a potentially unstable atmosphere into Kansas, as we see Mexico heat level air appear in Kansas at that time. The slightest shower may turn into a huge storm.
Nothing in the Southeast to speak of.
This has been a daily forecast discussion. Check back for another one tomorrow at 7:30 pm CDT.
