####018002185#### FNUS21 KWNS 240704 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0103 AM CST Fri Jan 24 2025 Valid 241200Z - 251200Z ...Synopsis... A broad upper trough migrating southeastward out of southwestern Canada will support widespread surface pressure falls across the inter-mountain West and central High Plains. Breezy conditions are expected along the southern CA coast and southern Plains in response to the broad-scale, low-level mass response with an attendant increase in fire weather potential. ...Southern California Coast... 06 UTC surface observations show a 1030-1036 mb surface high over parts of the Great Basin, which is promoting a moderate offshore pressure gradient along the southern CA coast. Areas of 15-25 mph are expected to persist through the early morning hours and into the afternoon before diminishing through late afternoon/evening as the surface high weakens amid surface pressure falls related to the approaching upper wave. While the strongest winds may be temporally offset from peak diurnal heating, a prolonged period of offshore/downslope winds has resulted in very low (5-15%) RH along the coast, which will support fire weather concerns through the morning and early afternoon. ...Southern Plains... Surface high pressure currently over southern TX (as of 06 UTC) is expected to shift east over the next 12 hours. Concurrently, surface pressure falls along the central High Plains ahead of a weak cold front will promote strengthening pressure gradient wind across the southern Plains. 15-25 mph southwest winds are likely across much of western TX into southwest OK with RH reductions generally between 15-25%. Elevated fire weather conditions are likely, and a few locations may experience periods of critical conditions. However, recent ERC analyses suggest that fuels are only modestly receptive (between the 50-80th percentiles), which should limit fire spread potential outside of areas with heavy loading of 1 and 10-hour fuels. ..Moore.. 01/24/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
