An upper-level ridge will continue to move eastward through the West and into the Plains today. By the end of the period, cyclonic flow aloft will return to the West Coast. At the surface, a broad anticyclone will be situated within the Great Basin into the southern Plains. The strength of the surface high will peak early in the period. ...Southern California... Elevated to briefly critical fire weather conditions are again expected across much of the Transverse and Peninsular Ranges. A similar offshore gradient, though most likely weaker, to Friday morning can be expected this morning. The pressure gradient will relax by the afternoon. Current surface observations in the region continue to show widespread RH below 20% and most locations will not significantly recover by morning. Winds of 15-20 mph will be most prevalent with the typical wind-prone locations seeing higher speeds. Those terrain-favored areas are also where critical conditions may occur briefly during the early to mid morning. ...North-Central Montana... Locally elevated conditions may occur in the lee of the Lewis Range as a weak surface trough develops along with modest flow enhancement aloft. Confidence in winds reaching 15-20 mph is relatively high, but RH may remain above critical thresholds. A small area of remaining dry fuels exists and could support fire growth should RH fall to 20-25%. ..Wendt.. 10/16/2021 ...Please see www.spc.noaa.gov/fire for graphic product...
