Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1255 AM CDT Sat Sep 19 2020 Valid 191200Z - 201200Z ...Synopsis... An upper-level trough will into the northern Rockies and adjacent Plains today. A surface cyclone will deepen in the Canadian Prairie with an attendant lee trough sharpening southward into the central High Plains. A cold front will progress south and eastward, particularly across the northern Rockies as the trough swings through. ...Southern Great Basin into central Rockies... Ahead of the advancing front, moderate to strong mid-level winds will combine with an enhanced surface pressure gradient to drive 15-25 mph surface winds. RH may fall below 15% in some locations, but will more commonly range from 15-20%. While some brief and locally critical conditions may occur, short duration remains too much of a concern to introduce critical highlights. This is especially the case for central/eastern Wyoming where RH will recover behind the boundary. ...Central High Plains... Relatively dry southerly surface winds are expected to increase to 15-20 mph during the afternoon as the lee trough deepens. A narrow corridor of elevated fire weather conditions is expected to develop along a west-east moisture gradient where RH will fall to around 20-25%. ..Wendt.. 09/19/2020 ...Please see www.spc.noaa.gov/fire for graphic product...
