Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0152 AM CDT Tue Sep 28 2021

Valid 291200Z - 301200Z


Broad troughing will linger over much of the western US Wednesday,
supporting widespread shower and thunderstorm activity across the
central CONUS. To the east, high pressure will strengthen as
mid-level flow weakens and shifts to the north. At the surface,
gusty northerly winds through much of California will promote weak
to moderate offshore flow, along with warming and drying conditions.
Fire weather threats are expected to remain mostly local in nature,
though periodic elevated conditions are possible across portions of
southern California mainly late in the forecast period and into Day

In the wake of the cold front, gradient winds are forecast to remain
light and northerly through much of the day across central and
southern California. Warm and dry surface conditions are expected
with diurnal RH minimums near 20%. Poor RH recoveries should persist
into the overnight and early Day3/Thursday as east northeasterly
winds begin to increase in response to building high pressure across
the Great Basin. Weak offshore flow will likely develop across the
southern Coastal Ranges with some chance for locally elevated fire
weather conditions overnight.
