Thursday’s Weather Outlook; West/Plains/Mississippi Valley/Southeast System


On Thursday, a system will begin to slowly push through the West. Showers and storms will be possible in the lower elevations of the West and in the Plains. Showers and storms will develop along and ahead of a cold front from the Inter-Mountain West up into Minnesota. With limited instibility, some of the storms may become severe. Along a northward moving warm front, showers and storms will be possible in portions of the Mississippi Valley. With limited instibility, a few storms may become severe. Along the warm front in the Southeast, showers and storms will also be possible. There is a slight risk for severe storms in portions of Georiga. CAPE values will be around 3000 J/KG, LI’s of -8 and Effective Bulk Shear of 20-45KT. This along with the warm front moving through the area, will help storms become severe. The main threats will be hail and damaging winds. On the north side of the system, snow will be possible in the higher elevations of the Northwest. Below is the severe weather and snowfall outlook for Thursday.
