FNUS21 KWNS 091642 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1041 AM CST Sat Dec 09 2023 Valid 091700Z - 101200Z The previous forecast remains on track with no changes required. Latest surface observations within the southern CA coastal ranges show areas of elevated to critical fire weather conditions with winds gusting between 25-50 mph and RH in the upper teens and low 20s. Such conditions will likely persist through tonight and into early Sunday morning. Across southern TX, dry conditions are noted in recent observations with a gradual increase in winds still likely this afternoon. See the previous discussion below for additional information. ..Moore.. 12/09/2023 .PREV DISCUSSION... /ISSUED 1141 PM CST Fri Dec 08 2023/ ...Synopsis... An upper-level trough will amplify as it moves into the Southeast today. This will push a cold front through the Plains to near the Appalachians. Surface high pressure will increase within the Great Basin and Four Corners regions. ...Southern California... Offshore winds will likely be maximized early this morning. Winds of 20-25 mph (with higher gusts) will overlap with at least marginally reduced RH. RH values will fall to near 10-15% in some locations by the afternoon. Winds will slowly lose some intensity with time, but should remain 15-20 mph for several hours. Lower elevation fuels will be the primary driver of fire spread. However, these fine fuels are only marginally dry at present. Elevated fire weather concerns are possible where these fuels are driest. ...Texas... Elevated fire weather is possible within part of the Permian Basin into the Edwards Plateau. Post-frontal winds will be 15-20 mph amid 15-20% RH. Locally lower RH could occur where a greater downsloping wind component exists. Fine fuels are marginally dry and will support a low-end threat for a large fire. Cold advection will tend to limit the fire weather threat, particularly farther north, as RH will likely remain above critical thresholds in those areas. ...Please see www.spc.noaa.gov/fire for graphic product... $$
