ZCZC SPCFWDDY1 ALL FNUS21 KWNS 221619 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1019 AM CST Wed Nov 22 2017 Valid 221700Z - 231200Z An Elevated fire weather area has been introduced across inland areas of southern California. Surface high pressure -- located over the Great Basin -- is promoting low-level dry offshore flow across the inland areas of southern California this morning. As of 16Z, multiple surface observations across the coastal foothills and canyons are indicating sustained surface winds in excess of 15 mph (with higher gusts) in conjunction with RH values near 20%. These Elevated fire weather conditions are expected to continue through the afternoon as diurnal heating allows RH values to drop to near 15% and sustained surface winds remain around 15-20 mph (locally higher). ..Elliott.. 11/22/2017 .PREV DISCUSSION... /ISSUED 1234 AM CST Wed Nov 22 2017/ ...Synopsis... An amplified west-to-east, ridge-trough mid-level pattern will continue on Wednesday. The ridge across the Southwest and Great Basin will lead to warm/dry conditions, albeit with light winds. Across the East, despite the presence of stronger mid-level flow and surface-pressure gradients allowing for strong/gusty winds across some locations, relatively cool surface temperatures will act to keep relative humidity above elevated-to-critical fire-weather thresholds. ...Please see www.spc.noaa.gov/fire for graphic product...
