...Synopsis...
A deepening trough over the western US is forecast to amplify as
southwesterly flow over much of the western US increases. A lee
trough over the High Plains will bolster downslope surface winds
across the western US. To the east, high pressure should continue to
intensify supporting offshore winds over New England behind an
offshore cold front. Elevated fire-weather conditions are possible
given unusually warm, dry and windy conditions over the CONUS.
...Lee of the Rockies and High Plains...
Increasingly strong west/southwest flow ahead of the trough will
support gusty winds across the Rockies and Northern High Plains.
Near a lee trough, downslope winds of 15-20 mph are likely,
coincident with a relatively dry air mass with RH values near 20%.
Sustained elevated to locally critical fire-weather conditions
appear likely across parts of central MT, eastern WY, and into
western parts of the Dakotas and NE/CO. Here, fuels are the most
receptive and the longest overlap of favorable meteorological
conditions is expected.
...Southern New England...
While slightly weaker than prior days, offshore flow should continue
across parts of the East Coast and southern New England today. Gusty
winds near 15 mph are possible, mainly closer to the coast, where RH
values are still expected to be near 30-35%. A few hours of elevated
fire-weather conditions are possible within record dry fuels.
Concerns will ease as high pressure shifts eastward, weakening winds
and cooler air mass will moderate RH values into Monday.
