...Severe thunderstorms possible for portions of the Great Lakes...
...Heavy rain and flash flooding possible for portions of Texas...
...Dangerously hot temperatures expected for portions of the Pacific
Northwest...
A cold front will bring showers and thunderstorms to areas from the Upper
Midwest and Great Lakes to the southern plains today. Some storms could be
severe across portions of the Great Lakes. Please refer to products issued
by the Storm Prediction Center for further details on the severe weather
threat. On Sunday the cold front will move east, bringing showers and
thunderstorms to the Northeast and Mid-Atlantic regions. Behind the cold
front, a much cooler air mass will move into the central U.S. High
temperatures today will be 10 to 20 degrees below average for much of the
central and northern plains. Cooler temperatures behind the front will
spread into the Great Lakes and Ohio valley on Sunday, and into the
Northeast by Monday. Farther south, the cold front will become stationary
across the southern plains by Sunday. Storm may produce heavy rainfall
today and Sunday across portions of Texas, and flash flooding is possible.
High pressure aloft will keep the West Coast hot and dry through the
weekend. Dangerously hot temperatures are expected once again today across
the Pacific Northwest, where afternoon highs are forecast to be 10 to 20
degrees above average. Some areas could surpass 100 degrees. The ridge of
high pressure will begin to break down on Sunday, allowing a cold front to
approach the Pacific Northwest late on Sunday. Temperatures will be
slightly cooler on Sunday relative to today, but significantly cooler
temperatures, much closer to normal levels, are expected by Monday in the
wake of the cold front.
