...Synopsis...
Upper-level troughing over the north/central U.S. will gradually
shift eastward into the Great Lakes region, while upper ridging
strengthens and lifts northward across the western CONUS. A dry
airmass will persist in the Interior West amid a very dry fuelscape,
with stronger flow aloft remaining over the northern Colorado
Plateau into southwest Wyoming. Elevated highlights have been
maintained where west-northwesterly sustained winds of 10-20 mph
(gusts of 20-30 mph) are likely amid minimum RH values of 5-15% this
afternoon. Farther west, daytime high temperatures of 100+ degrees F
and 5-15% RH will occur across the California valleys and
surrounding terrain. The spatial extent of sustained 15+ mph winds
for 3 hours or greater will be limited, precluding an introduction
of fire weather highlights; however, periods of onshore flow
exceeding 15 mph are possible across localized interior regions and
terrain-favored areas, supportive of locally elevated fire concerns
where fuels are receptive.
