####018002013#### FNUS28 KWNS 152112 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0310 PM CST Sun Dec 15 2024 Valid 171200Z - 231200Z Zonal upper-level flow across the CONUS will begin to amplify Tuesday into Wednesday. An upper-level ridge will develop across the West with shortwave troughs progressing through areas east of the Divide. With colder air and precipitation potential for many areas east of the Rockies, fire weather concerns will generally remain low. Some portions of the central High Plains vicinity will not observe much precipitation. Dry and windy conditions are possible in both the post-frontal environments as well as when surface lows deepen in the Plains. Given the antecedent cooler temperatures, it is not clear more than locally elevated conditions will occur. Fire weather concerns will primarily be focused in southern California as high surface pressure intensifies in the Great Basin Tuesday into Thursday. ...Southern California... Model guidance remains consistent in an enhanced offshore pressure gradient maximizing Tuesday night into Wednesday morning. There is moderate confidence in at least a low-end critical offshore pressure gradient, though models have tended to back off on the magnitude slightly over the past couple of days. The greatest level of uncertainty exists with how low RH will fall. Available high resolution guidance from the CANSAC WRF suggests 15-20% RH will be most typical. That being said, the most widespread critical fire weather may hold off until Wednesday morning when some heating will occur and winds will still be moderately strong. A brief period of critical fire weather could occur very late Tuesday and trends in guidance will continue to be monitored. Given the remaining uncertainty, 40% critical probabilities will be maintained this outlook. ..Wendt.. 12/15/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018000271#### FNUS38 KWNS 152112 PFWF38 DAY 3-8 FIRE WEATHER OUTLOOK AREAL OUTLINE NWS STORM PREDICTION CENTER NORMAN OK 0310 PM CST SUN DEC 15 2024 VALID TIME 171200Z - 231200Z FIRE WEATHER OUTLOOK POINTS DAY 3-8 ...
