...Heavy rains and possible flash flooding Monday night/early Tuesday over
the Lower Mississippi Valley. Heavy rains and potential severe weather
across portions of the Southeast on Tuesday...
...Below average temperatures for the Pacific Northwest and much of the
East over the next two days...
...Heavy snows likely through the Cascades and into the Northern Rockies.
Light snows possible from northern New York State into northern New
Active weather expected ahead of an area of low pressure forecast to move
east from the Southern Plains into the Lower Mississippi Valley tonight
and across the Southeast on Tuesday. Thunderstorms are expected to
continue to enhance late this afternoon across the Southern Plains, moving
into the Lower Mississippi Valley tonight. These storms will likely
produce heavy rains and the potential for localized flash flooding. This
heavy rain potential will continue on Tuesday across the Southeast,
Southern Appalachians and Southern Mid Atlantic as the storm moves
eastward. In addition, severe thunderstorms may affect portions of the
Southeast from southern Alabama, Southern Georgia, far northern Florida
into far southern South Carolina.
Large portions of the country over the next two days will be in a cool
spring weather pattern as upper level lows are anchored across the Pacific
Northwest/southwest Canada and over the Northeast. These upper lows will
keep temperatures below average from the Pacific Northwest, Northern
Rockies and into the northern High Plains and across much of the east.
The exception will be along the Gulf coast into Florida where much above
average temperatures will continue Tuesday before cooler temperatures move
in behind a cold front on Wednesday. Above average temperatures also
likely from southern California, through the Southwest and across much of
Plains over the next two days.
In addition to the closed upper lows supporting below average
temperatures, they will also support heavy snows from the Cascades of
Washington & Oregon into the Northern Rockies. Snow totals over the next
two days may be in the 1 to 2 foot range across those areas. Much lighter
snows are also possible across northern New York State and northern New
England where 1 to 3 inches are possible.
