…Widespread record high temperatures possible across portions of the
Upper Midwest and Northern/Central Plains…
…Critical Fire Weather Risk over parts of the Northern Plains today then
Southern High Plains through the rest of the week…
A low pressure system will move into the Atlantic today while producing
scattered showers and thunderstorms across the Southeast. Conditions
should improve on Tuesday. Meanwhile, a potent low pressure system will
dip into the northern tier states today, bringing strong winds and the
potential for fires to the region. Ahead of this system, warm southerly
flow will support anomalously high maximum temperatures in the 50s and 60s
with some isolated areas possibly exceeding 70 degrees. These anomalous
maximum temperatures will represent 20-40 degree departures from average
for much of the Northern/Central Plains and Upper Midwest, where
widespread records may be tied or broken. The arrival of the attendant
cold front this afternoon/evening will moderate temperatures as well as
increase potential for fires. The Storm Prediction Center issued a
Critical Risk of Fires for much of the Dakotas where dry and windy
conditions will support wildfires.
An upper trough in the East Pacific will propagate through the Southwest
on Tuesday, sending dry downslope flow from the Southern Rockies into the
Southern High Plains. The addition of sustained winds, likely between
15-25 mph, will support a Critical Risk of Fires for portions of far
southeast Arizona into southern New Mexico and far western Texas. The
Critical Fire Risk is likely to continue over the Southern High Plains
through the rest of the week. An amplified upper trough will bring
unsettled weather to the West Coast Tuesday night into Wednesday.
