...Heavy rain and flash flooding possible across portions of Texas...
...Showers and thunderstorms expected today across much of the eastern
U.S...
...Cold front to bring cooler temperatures to the Pacific Northwest by
Monday...
A cold front will move east from the Ohio valley into the Northeast and
Mid-Atlantic region today, bringing showers and thunderstorms to much of
the Eastern Seaboard into tonight. The trailing end of the frontal
boundary will become stationary from Texas to the lower Mississippi
valley, keeping showers and thunderstorms commonplace through today and
tonight. Storm may produce heavy rainfall across portions of Texas, and
flash flooding will continue to be a threat. The stationary front will
remain across the same areas on Monday and Tuesday, but will begin to
slowly weaken. As a result, showers and thunderstorms should become more
scattered in nature.
Behind the cold front, a cooler air mass will move into areas from the
Upper Midwest and Ohio valley today to the Northeast and Mid-Atlantic on
Monday. Afternoon high temperatures are forecast to be 5 to 10 degrees
below average in these areas.
A ridge of high pressure that has kept hot weather in place across the
Pacific Northwest the past couple days has begun to weaken. As a result, a
cold front will move into the Pacific Northwest from British Columbia late
today. The cold front will be accompanied by very little in terms of
precipitation, but it will usher a cooler air mass into the region in its
wake. Portions of interior Washington, and much of Oregon will still see
one more day of above average temperatures today, but temperatures should
decrease to near or slightly below average for most of these areas on
Monday.
