...Discussion...
Weak upper troughing will enter the western CONUS on Day 3/Sunday as
a secondary decaying upper-level trough pushes into the central
Plains, bringing precipitation to the Northern Rockies and northern
Plains. Meanwhile, a southward progressing cold front and related
precipitation will bring some temporary relief to the southern
Plains through early next week. Residing high pressure over the
Southeast is expected to maintain hot and mostly dry conditions
across the lower Mississippi Valley through the middle of next week,
but prevailing light winds should suppress overall fire weather
concerns. Ensemble guidance is in general agreement for ridging to
build across the central-western CONUS late in the workweek as an
upper trough evolves in the eastern Pacific, indicating stronger
southwest winds could return to the Pacific Northwest and northern
Great Basin. However, an expected marginal fuelscape should limit a
broader fire weather threat.
