207 FNUS21 KWNS 161643 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1142 AM CDT Sun Jun 16 2024 Valid 161700Z - 171200Z An Elevated risk area has been added for portions of the southern Sierra Nevada and western Transverse Ranges in southern California. RH is somewhat marginal for the area, with a minimum of 15-25% expected. However, strong winds (40-50 mph gusts with higher gusts in mountain gaps), rapid drying of fuels, poor overnight RH recovery, and observed rapid growth of the Post fire indicate the threat for additional fire activity in the area. Otherwise, see the previous discussion for further details. ..Supinie.. 06/16/2024 .PREV DISCUSSION... /ISSUED 0151 AM CDT Sun Jun 16 2024/ ...Synopsis... A deepening western trough will bring an increase in southwesterly flow across much of the desert Southwest this afternoon. Fuels in this region have seen significant drying after several days of warm and dry conditions. Guidance indicates fuels in this region are critically dry, with recent ERCs data indicating 90th percentile for dryness across much of northern and central Arizona. This is further supported by active recent fire activity in this region. Relative humidity reductions to 5-10 percent will overlap sustained winds 15-20 mph across central/northern Arizona, southern Utah, and far southeastern Nevada where a Critical delineation was maintained with this outlook. Outside of this region, a more broad area of Elevated fire weather conditions will be possible across much of central/southern Utah into southern Arizona, where there is less confidence is sustained Critical wind speeds. Elevated conditions may also extend into portions of western Nevada in the lee of the Sierras. In this region, afternoon relative humidity reductions to 15-20 percent will overlap sustained winds 10-15 mph (locally higher) amid modestly receptive fuels. ...Please see www.spc.noaa.gov/fire for graphic product... $$
