National Situation Update: Sunday, July 26, 2009

Homeland Security Threat Level: YELLOW (ELEVATED).

National Weather Forecast

Northeast
Areas from New England to the Middle Atlantic coastal region will see scattered thunderstorms, some severe, on Sunday. Highs will be in the mid to upper 70s from West Virginia to Maine and in the 80s across the eastern Mid-Atlantic. Scattered thunderstorms will prevail across the region on Monday but Tuesday will be mainly dry. Scattered thunderstorms will return by Wednesday and continue for the rest of the week. 
South
Look for scattered thunderstorms on Sunday from Virginia to eastern Texas ahead of a cold front. Highs will range from between 85 and 95 across the Southeast to over 100 in southern Texas. More scattered thunderstorms are likely across the South on Monday as a front to the north stalls and weaken. Another front will push southward on Monday and Tuesday and once again stall to the north of the region.
Midwest
The Great Lakes area will see scattered showers and thundershowers on Sunday along with cool temperatures. A few thunderstorms may pop later in the day across the high Plains, as well. Most of the rest of the Midwest will enjoy a relatively pleasant Sunday. Highs will range from the 70s in the Great Lakes to the 80s and lower 90s in the Plains. The next cold front will trigger showers and thunderstorms across the Upper Midwest on Monday and precipitation will sink down to the Ohio Valley back to the southern Plains on Tuesday.
 West
The main weather story over the far West, except for coastal areas, will be very hot. From Monday through Thursday, temperatures in the California-to-Washington corridor will soar as high as 5 to 20 degrees above average while areas from the Rockies eastward will dip as low as 5 to 20 degrees below average. Portland will see low 90s on Sunday and perhaps triple digits Monday through Wednesday. Thunderstorms will be most common from the Rockies into the high Plains. A few dry thunderstorms are occasionally possible as far west as the Sierra and Cascades. The fire danger will remain high across the Northwest for awhile.  (NOAA, National Weather Service, Various Media Sources)
