Thunderstorms expected to develop across portions of the Central Plains and Missouri Valley on Wednesday ahead of a cold front. Across portions of west Texas and southeastern New Mexico, a few thunderstorms will be possible as instability builds through the afternoon. Thunderstorms will continue across west Texas and southeastern New Mexico on Thursday, allowing for the risk for excessive rainfall and flooding.
Thunderstorms have developed across portions of Wisconsin and Illinois. These storms should continue through the morning with hail in excess of 0.75 inch, wind gusts in excess of 50 mph, heavy rain, and frequent lightning the main hazards. Further to the southwest, thunderstorms will be possible across the mid-Mississippi Valley and into the Great Plains along a stalled frontal boundary. As instability increases with daytime heating, there will be a potential for a few strong to severe thunderstorms across Region 1, mainly during the afternoon hours. The primary hazards with these storms will be gusty winds and hail. The severe threat should begin to diminish by the evening hours as instability decreases and the front begins to move off to the southeast.

Excessive Rainfall Risk Outline for Thursday
A broad non-tropical area of low pressure located a few hundred miles east-northeast of the northern Lesser Antilles (green oval) is producing widespread cloudiness and showers. Although this system is expected to strengthen into a non-tropical gale over the central Atlantic within the next day or so, it could acquire some subtropical characteristics late this week or this weekend while it moves northward or north-northeastward over the north-central Atlantic.

A Look Ahead
By the weekend, an area of low pressure will bring rain to portions of the Pacific Northwest. Rain chances will increase across the Southern Plains on Sunday as an area of low pressure develops in the lee of the Rockies. Rain will continue for portions of the Central and Southern Plains into early next week,
