...17z Update...
Minimal changes were made to the ongoing forecast. The Elevated area
over southern California was adjusted slightly to better conform to
the terrain of the southern San Joaquin Valley. Isolated 15-20 mph
northerly wind gusts, extremely warm temperatures, and very low RH
are possible this afternoon and evening.

Locally dry and breezy conditions remain possible across the Wasatch
and the higher terrain of the eastern Great Basin. However, winds
continue to trend weaker with most guidance and should remain below
Elevated criteria. See the previous discussion for more information.

.PREV DISCUSSION... /ISSUED 0142 AM CDT Thu Jul 04 2024/

...Synopsis...
A mid-level trough will move across the central U.S. as upper
ridging builds back over the Interior West today. Stronger
deep-layer northwesterly flow will overspread the West Coast, that
with boundary-layer heating/mixing, may reach the surface in terrain
favoring locations. Once such place is the San Joaquin Valley area
in central California, where 15 mph sustained northwesterly surface
winds may coincide with 10-15 percent RH by afternoon peak heating,
warranting the continuation of Elevated highlights. Dry and
occasionally breezy conditions may also be expected across much of
the Great Basin into the central Rockies this afternoon. Though
widespread 10-15 percent RH should be common, stronger surface winds
are not likely to be particularly widespread. Nonetheless, locally
windy conditions (and associated wildfire-spread potential) are
possible in terrain favoring areas.
