ZCZC SPCFWDDY2 ALL FNUS22 KWNS 241844 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0144 PM CDT Thu Sep 24 2020 Valid 251200Z - 261200Z ...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST WYOMING AND NORTHWEST COLORADO... The previous forecast remains on track with only minor adjustments needed. One such change was to expand the critical risk area into northwest Colorado where down slope warming and drying should support at least a few hours of critical fire weather conditions. This idea is supported by recent ensemble guidance, which shows reasonably high probabilities for sustained critical conditions. To the west, localized critical conditions are likely for adjacent areas of northeast UT, especially for areas that typically see terrain-enhanced winds. However, coverage appears to be too limited for further westward expansion at this point. ..Moore.. 09/24/2020 .PREV DISCUSSION... /ISSUED 0159 AM CDT Thu Sep 24 2020/ ...Synopsis... Flow across the northern tier of the U.S. will become zonal on Friday. A belt of strong mid-level flow will extend from the Northwest into the northern and central Rockies. The upper-level pattern will favor the cold front remaining mostly stationary from the northern Great Basin into central Wyoming. Lee troughing will be present again, though more subdued than Thursday. ...Southern Wyoming... Mid-level winds will increase as compared to Thursday. Coupled with the lee trough to the east, surface winds may increase to 20-25 mph with localized areas near 30 mph. The primary questions will be how low RH will fall and for how long. An increase in mid/upper moisture is present in forecast soundings which will mean greater potential for mid/upper-level clouds. The highest confidence in 15% RH coincident with 20+ mph winds is in parts of southeastern Wyoming. Locally critical may occur elsewhere in southern Wyoming, but uncertainty is high in the duration of such conditions. ...Eastern Great Basin and vicinity... A similar scenario to Thursday will again play out. Modest to moderate mid-level winds will combine with slightly enhanced surface winds ahead of the boundary to produced elevated fire weather conditions. Winds will mostly range from 15-20 mph with 10-20% during the afternoon. Locally critical conditions could also occur, but spatial extent and duration are expected to be limited. ...Please see www.spc.noaa.gov/fire for graphic product...
