Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1124 AM CDT Sun Aug 18 2024

Valid 181700Z - 191200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHWEST NEVADA...

The previous forecast remains valid with minimal changes. The
elevated area over portions of eastern NV was trimmed slightly to
account for prior precipitation. Critical fire-weather concerns will
remain possible with gusty winds and low humidity over central
portions of NV. Brief elevated fire-weather conditions are also
possible in the lee of the Sierra and northern Great Basin. While
fuels are not as dry here (50-60th percentile seasonal ERCs), some
drying from gusty downslope winds of 15-20 mph and RH below 15% may
support a risk for elevated fire-weather potential for a few hours
this afternoon. Otherwise, see the prior discussion  for more
information.

.PREV DISCUSSION... /ISSUED 0147 AM CDT Sun Aug 18 2024/

...Synopsis...
A mid-level impulse embedded in the broader cyclonic flow aloft will
traverse the West Coast and impinge on the Pacific Northwest while
an upper ridge persists across the central U.S. today. The departure
of upper support will result in somewhat weaker isallobaric flow
from the lee of the Cascades into the Great Basin co*pared to
yesterday. Nonetheless, some residual gradient flow, co*bined with
robust boundary layer mixing, will support dry and windy conditions
during the afternoon to the lee of the Sierra into the western Great
Basin, where Elevated highlights have been maintained. Critical
highlights remain where guidance consensus shows the greatest chance
of 20+ mph sustained southwesterly surface winds overlapping with 15
percent RH and fuels receptive to wildfire spread.
