Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1152 PM CDT Sun Jun 23 2019
Valid 241200Z - 251200Z
A mid-level wave over the central Plains will eject toward the
western Great Lakes throughout the forecast period, resulting in
quasi-zonal flow aloft from northern California eastward to the
central Plains. Some of this stronger flow will occur atop a dry,
deeply mixed low-level airmass over Nevada, resulting in areas of
elevated fire weather.
Models (GFS and to a lesser extent RAP) continue to indicate at
least a few localized areas of 20+ mph westerly surface winds
developing in the lee of the Sierras during the afternoon and early
evening. This flow will occur as RH values fall to around 5-15%.
The extent of fire weather conditions will be mitigated by marginal
dryness of fuels, with only finer fuels supporting fire spread in
the region. Nevertheless, atmospheric conditions are consistent
with elevated fire weather thresholds, and an attendant delineation
remains in place.
