A mid level disturbance will move across the central Rockies later today helping to develop a storm system over the plains tonight and into Thursday. An active jet stream should help to intensify this storm as it moves from the Texas Panhandle toward the Great Lakes region into Friday.
A Pacific cold front will accompany this system allowing a line of thunderstorms to develop ahead of the front over Texas and Oklahoma by early Thursday. These storms will move through Louisiana Thursday afternoon and evening. The Storm Prediction Center puts parts of the south in a "slight risk" for severe thunderstorms. This area runs from Jackson, Mississippi northeast to Detroit. Heavy rains on top of a large snow pack could cause flooding in the Ohio Valley.
Cooler and drier air will spill into the area behind the front. Rain chances will drop off early Friday. Pleasant conditions are forecast for the weekend.
