by David Moran, on May 29, 2018 11:29:06 AM

Thunderstorms are expected to develop across portions of the western and central Plains on Tuesday as an upper level disturbance moves across the region. In the Northern Plains and Upper Midwest, thunderstorms will develop along and ahead of a frontal boundary. The remnants of Alberto will bring the potential for thunderstorms to portions of the Southeast. As the remnants of Alberto continue to move northward, excessive rainfall is expected from portions of the Southeast into the Ohio Valley. Thunderstorms across the Central Plains may allow for a risk of excessive rainfall and flash flooding.

Risk for Thunderstorms across the Western and Central Plains on Tuesday
A complex of showers and thunderstorms is currently weakening across Kansas and Oklahoma. Outflow boundaries generated by this morning's activity are likely to allow for the development of additional and stronger thunderstorms this afternoon and evening. The strongest of the storms will likely develop across the west central High Plains during the early to mid afternoon. Storms will progress east-southeastward into east central Kansas, as well as northern and central Oklahoma, from the late afternoon through the early evening hours. Hail to the size of baseballs will be the primary hazard, followed by damaging winds. An isolated tornado or two cannot be ruled out.

Risk for Excessive Rainfall across the Central Plains on Tuesday
Showers and a few thunderstorms are ongoing across portions of western and central Kansas and portions of northern Oklahoma. While ongoing activity should weaken through the morning, outflow boundaries should serve as a focus for new development during the afternoon and evening. Hourly rainfall rates may exceed 1-2 inches within some of the heavier thunderstorms, leading to a risk of flash flooding.

Thunderstorms Tuesday across the Northern Plains and Upper Midwest
The leading edge of a weakening area of showers across central Nebraska and northern Kansas will continue to move northeastward through the day. Another round of thunderstorms is expected to develop during the afternoon as daytime heating increases. In addition, an upper level disturbance will move into the region, allowing for a risk for damaging winds and large hail this afternoon through this evening.

Potential for Thunderstorms across the Southeast on Tuesday
Thunderstorms will continue across the Southeast as the remnants of Alberto continue to move northward. Damaging winds and perhaps a brief tornado will be possible from central Tennessee into northern Georgia and western South Carolina. Cloudy skies and ongoing showers will limit the amount of daytime heating and destabilization, however, a few strong storms should develop. The strongest of the storms should occur during the afternoon before weakening in the evening.

Excessive Rainfall Tuesday for the Southeast and Ohio Valley
The remnants of Alberto will overspread northern Alabama and southern Tennessee over the next 24 hours. Rainfall rates may exceed 1-2 inches per hour, especially during the afternoon at the peak of daytime heating. Rainfall amounts of 4-6 inches are forecast in some localized areas, leading to flash flooding and river flooding. Elsewhere, rainfall amounts of 2-4 inches with locally higher amounts are expected throughout much of the Southeast and the Ohio Valley. Frequent squall bands are likely to redevelop as far south as the Gulf Coast and as far east as the Carolinas, leading to the potential for localized flash flooding well away from the center of circulation.

Thunderstorms Wednesday across Nevada, Idaho, Montana, and Wyoming
Strong heating is anticipated Wednesday afternoon ahead of an approaching cold front. By mid to late afternoon, scattered showers and thunderstorms, a few severe, are likely to develop along and ahead of the front. Strengthening upper level winds ahead of a Pacific disturbance will support a threat for damaging winds. A few thunderstorms may persist through the evening before ending overnight.

Thunderstorm Potential for the Western and Central Plains on Wednesday
An upper level trough will aid in the development of widely scattered thunderstorms across the Rockies by mid to late Wednesday afternoon. These storms will shift eastward into the western High Plains during the late afternoon and early evening. Late Wednesday night, a few isolated severe storms are likely across southern Kansas into central Oklahoma. Large hail and damaging winds will be the primary hazards with these storms.

Risk for Thunderstorms Wednesday across the Great Lakes
The remnants of Alberto will make their way into Indiana and Ohio by Wednesday afternoon. As instability increases near and to the east of the low and wind shear increases, thunderstorms will develop. Damaging winds and an isolated tornado will be the primary hazards with these storms.

Excessive Rainfall from the Ohio Valley into the Mid Atlantic Wednesday and Thursday
The remnants of Alberto will begin to interact with a stalled front over the Ohio Valley and Mid Atlantic Wednesday into Thursday. Most locations will not see rainfall totals in excess of 1-2 inches. However, areas receiving multiple rounds of thunderstorms will receive rainfall amounts in excess of 3 inches. Isolated flash flooding cannot be ruled out.

Thunderstorms for Idaho, Montana, and the Dakotas on Thursday
Low level moisture and forcing from a mid level trough will allow for the development of afternoon thunderstorms across the region. Damaging winds and large hail will be the primary hazards with some of the more organized thunderstorms during the afternoon and early evening.

Thunderstorm Potential Thursday from the Central Plains into the Ohio and Tennessee Valleys
Thunderstorms may develop from the Central Plains into the Ohio and Tennessee Valleys on Thursday. Activity ongoing from Wednesday night and early Thursday morning may limit thunderstorm potential later into Thursday. Damaging winds and hail will be the primary hazards as a mid level disturbance moves out of the Plains.

Risk for Excessive Rainfall across Montana and Idaho Thursday
A slow moving cold front will allow for the development of several rounds of heavy thunderstorms on Thursday. Rainfall amounts will range from 0.50-1.00 inch with locally higher amounts. Previous heavy rains combined with the potential for additional heavy rain may contribute to a risk for excessive rainfall and localized flash flooding.

A Look Ahead
Showers and thunderstorms will continue across the Great Lakes and Ohio Valley on Friday as an area of low pressure and associated cold front moves through the region. Activity will move into the Northeast Friday evening. Late Friday into Saturday, thunderstorms may develop across the Northern High Plains as an area of low pressure develops over the region. By Saturday night into Sunday, thunderstorms may move into portions of the Ohio and Tennessee Valleys.
