Thunderstorms for the Plains on Tuesday
Storms are expected to develop today ahead of an area of low pressure and cold front stretching from the Dakotas into the Southern Plains. Any discrete thunderstorms may produce tornadoes, but storms should eventually congeal into a line and move northeastward. Winds will become the strongest after the line has developed.
Further south into the Southern Plains, thunderstorms will be more scattered. A few storms may produce large hail and damaging winds during the late afternoon and early evening before weakening.

Strong to Severe Thunderstorms on Tuesday from the Midwest into the Northeast
Rich moisture combined with daytime heating will create enough instability for the development of thunderstorms along a nearly stationary front across the region. Storms will develop during the early afternoon and will move out of the region. Significant severe weather is not expected, but a few isolated severe storms may develop.

Excessive Rainfall Risk Outline for Tuesday
Thunderstorm Potential on Wednesday across the Midwest, Southern Plains, and Mid Atlantic
Warm, moist air will be in place on Wednesday, stretching from Oklahoma and the Missouri Valley, northward, into the Great Lakes, and eastward into the Mid Atlantic. This area will be bounded by a stalled front over the Great Lakes and an approaching cold front to the west. Scattered showers and thunderstorms may develop with hail and damaging winds being the primary hazards. A slightly higher threat will exist across Wisconsin where large hail and severe winds are expected.

SPC Convective Outlook for Wednesday
Risk for Thunderstorms across the Ohio Valley on Thursday
The severe weather threat will diminish quite a bit by Thursday as the weather pattern transitions to more of a late summer pattern. High pressure will build into the Central US. A weak cold front pushing through the Ohio Valley may allow for the development of isolated thunderstorms, but no significant severe weather is expected. Small hail and severe wind gusts will be the primary hazards with any storms that do develop.

Showers and thunderstorms should increase across the Northeast on Friday as a warm front moves northward across the region. While severe impacts are not expected, a few storms may produce gusty winds and locally heavy rainfall. The threat for thunderstorms will continue through the weekend.
