...Heavy rain from the Ohio Valley to the East Coast...
...Scattered severe storms are likely Thursday afternoon and evening
across the Northern Plains...
...Elevated to Critical Fire Weather conditions are in place across much
of the Interior West...
After a rather stagnant weather pattern over the past couple of days,
things will begin to change more going into the end of the week. The
persistent upper ridge that has been anchored over the central U.S. will
now give way to a cold front exiting the Rockies that will emerge over the
Plains and bring cooler temperatures to much of the High Plains. This
same system will also increase the threat of severe weather across much of
the Northern Plains on Thursday, where the Storm Prediction Center has an
Enhanced Risk of severe storms from western Nebraska to northeast Montana.
Another cold front will be making southern progress across the Ohio
Valley and Mid-Atlantic region through the end of the week, bringing some
welcomed relief to the recent hot weather for these areas by Thursday and
especially on Friday. It will also be pleasantly cool for this time of
year across the West Coast and Intermountain West region before a warming
trend ensues for the weekend.
The historic heavy rainfall and flooding across parts of Mississippi and
Arkansas over the past couple of days will abate as the slow moving upper
level disturbance slowly lifts away from this region. The greatest
concern for heavy rainfall is now expected to be across portions of North
Carolina, Virginia, and West Virginia through Friday night. This is where
the combination of a slow moving mid-upper level disturbance and a surface
frontal boundary, in the presence of a very moist lower atmosphere, will
produce widespread moderate to heavy rain and embedded thunderstorms.
Rainfall totals are expected to be in the 1 to 3 inch range for many of
these areas over the next two days. The opposite will be true across much
of the Intermountain West and Rocky Mountains where enhanced wildfire
concerns will exist owing to gusty winds and very low humidity levels.
