National Weather Forecast

South:
The cold front which produced yesterday's severe weather over the Central Plains, Mississippi and Tennessee valleys has moved over the Southeast. Severe thunderstorms are possible from the Florida Gulf Coast to the Mid Atlantic. These storms will be capable of producing large hail, damaging winds and tornadoes. There is a tornado watch for portions of northern and central Alabama, of northern and central Georgia, and parts of southern and western South Carolina coastal waters until 10:00 am EDT. See  www.spc.noaa.gov/products/watch/ for the latest watches. Highs will range from the 80s across the northern part of the Region to 100 near the Mexican Border.

Midwest:
Strong thunderstorms and areas of heavy rainfall are expected this morning near the deepening surface low across much of the Midwest, Plains States and Lower Mississippi Valley.  The heaviest rainfall and thunderstorms will shift eastward into the Appalachians and mid Atlantic states tonight and Monday morning. The heavy rain will move eastward to the Great Lakes and Ohio Valley today. One to three inches of rain is forecast from South Dakota to Ohio. Localized flooding is possible due to the saturated ground; the additional water will contribute to ongoing flooding on the upper Mississippi.  Highs will range from the 40s near the Great Lakes and in the Ohio Valley to 70s over the Plains.

Northeast:
The weather system moving out of the Midwest will bring showery precipitation and thunderstorms to the Mid-Atlantic by midday and will move into New York state and Southern New England tonight
Rainfall amounts of two to four inches are possible by Monday. Given the already saturated ground localized flash flooding is likely. High temperatures will be range from the 60s in the mid Atlantic to the upper 40s.

West:
A frontal system will produce showers over the Pacific Northwest and rain (snow in higher elevations) across parts of Montana to northern Utah on Sunday. Temperatures across the Northwest will be relatively cool. However, melting snow may cause some localized flooding across the Northwest and northern Rockies. The Southwest will be hot, dry and windy. Fire danger remains high from southeast California to West Texas. (NWS, Storm prediction Center, Various Media Sources)

Severe weather Outbreak:

A deep surface low pressure system and associated frontal system moved across the Central Plains last night and into the mid Mississippi and Tennessee valleys this morning. This system combined with warm and moist air from the Gulf of Mexico produced a significant severe weather outbreak across the Plains and lower Mississippi Valley.
