Within a belt of broad northwesterly flow aloft across the West, an embedded shortwave trough will track southeastward across the Great Basin into the southern Rockies/High Plains. At the same time, an upstream midlevel ridge will build over the eastern Pacific and West Coast. This will favor strengthening surface high pressure over the Intermountain West, forcing a strong offshore pressure gradient across southern CA (LAX-DAG pressure gradient around -5 to -7 mb). Given a very dry air mass in place, critical fire-weather conditions are expected over the wind-prone Santa Ana Corridor surrounding the LA Basin, as well as along the mountains/valleys in San Diego County. Current indications are that this event will peak Day 3/Wednesday night into Day 4/Thursday morning. Thereafter, onshore flow should develop across southern CA, reducing the fire-weather threat through the weekend. ...Southwest into the southern Rockies and High Plains... Dry breezy conditions are expected across the region from Day 5/Friday into the weekend ahead of a large-scale trough. However, any fire-weather concerns should remain fairly localized owing to marginal fuels -- precluding Critical probabilities at this time. ..Weinman.. 01/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
