...Flash flooding and severe weather possible for portions of the north
central U.S. this weekend...
Showers and thunderstorms will continue to fire up along a frontal
boundary attempting to press south and east through the Upper Midwest and central Plains this weekend.
Storms will be developing in an increasingly moist airmass...giving them the potential to become organized and contain heavy rains.
The heavy downpours...combined with little to no progression of the surface boundary...will heighten the risk of flash flooding from eastern Nebraska to Minnesota and northwestern Wisconsin.
A second area of concern for flash flooding will be across eastern Montana and North Dakota...where a deepening surface low lifting from the lee of the northern Rockies should produce moderate to heavy rain and thunderstorms over the region.
Also...severe weather will be possible with storms developing over the northern to central High Plains this weekend.
Additional afternoons of numerous showers and thunderstorms are expected across the southeastern quarter of the Nation this weekend as an upper low stalled out over the Lower Mississippi Valley weakens and moisture continues to stream inland from the Gulf.
Activity should be more scattered in nature compared to recent days...reducing the threat for widespread flash flooding.
Farther north...strong high pressure expanding over the Eastern Seaboard should make for dry and pleasant conditions across the northeast and Mid-Atlantic states Saturday and Sunday.
