CORRECTED FOR WORDING

A mid-level trough will overspread the Plains states this weekend
and rapidly eject into the Northeast by early next week. At the same
time, another mid-level trough will amplify while impinging on the
West Coast and overspreading the Interior West by the end of the
period. With this upper-air pattern, multiple instances of surface
cyclone development are likely over the central U.S., which will
encourage low-level moisture return and ample precipitation
accumulations between the Rockies and Appalachians. Meanwhile
surface high pressure will persist over the Interior/Inter-Mountain
West. The net result will be relatively quiescent fire weather
conditions across much of the U.S., away from coastal areas through
the middle of next week.

Some wildfire-spread concerns will exist for portions of the
Mid-Atlantic for Days 3-4 (Friday), after a cold front passes the
region. By Friday afternoon, 15+ mph sustained westerly surface
winds will coincide with 30-40 percent RH for at least a few hours.
40% Critical highlights have been introduced for Day 3/Friday given
how dry the fuels are, and given that meaningful precipitation
accumulations are unlikely through at least the rest of the week.
Medium-range guidance depicts weaker surface wind fields over the
weekend (hence no Critical probabilities introduced), though dry
low-level conditions may promote at least localized wildfire-spread
potential.

Medium-range guidance also hints at potentially dry offshore flow
across southern California by the middle of next week. Low-end
Critical probabilities may be needed in later outlooks pending
guidance consensus and consistency in this scenario in medium-range
guidance over the next few days.
