A stationary front over the Southern Plains and Midwest will allow for isolated to scattered thunderstorms on Wednesday. As the front begins to move eastward on Thursday, thunderstorms are expected across the Ohio Valley. To the north of the area of low pressure associated with the cold front, heavy to excessive rainfall will be possible across the Eastern Great Lakes. By Friday, the risk for excessive rainfall will move into the Northeast.

Region 1

Severe thunderstorms will be possible this afternoon and evening along and ahead of a cold front stretching from the lower Ohio Valley through the Mid-Mississippi Valley and into the Southern Plains. Plentiful heating along this front combined with instability should allow for the development of thunderstorms; strong winds and large hail will be the primary hazards. While the tornado potential is low, a few brief tornadoes cannot be completely ruled out. The greater risk for severe thunderstorms will be across the Ozark Plateau. This activity is expected to gradually weaken due to the loss of daytime heating and the southward movement of the front. 

 

Update 12:36pm CDT: Severe thunderstorms capable of hail and damaging winds ongoing for portions of southwestern Missouri.

Tropical Update

An area of low pressure is located about 250 miles northeast of the Turks and Caicos Islands. Associated cloudiness and thunderstorms are located well east of the center due to strong upper level winds. Upper level winds are expected to become more conducive for this system to acquire tropical characteristics, and a subtropical or tropical cyclone is likely to form within the next couple of days. The low is forecast to move northward today and turn north-northwestward on Thursday before turning north-northeastward by the weekend. Regardless of development, locally heavy rainfall is possible over Hispaniola, Puerto Rico, and portions of the northern Leeward Islands today.

A Look Ahead

Light rainfall may linger across the Northeast over the weekend as an area of low pressure moves across the region. By early next week, an area of low pressure will move into the Pacific Northwest, bringing with it a chance of rain to the region.
