ZCZC SPCFWDDY2 ALL FNUS22 KWNS 250644 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0144 AM CDT Thu May 25 2017 Valid 261200Z - 271200Z ...CRITICAL FIRE WEATHER AREA FOR EASTERN AZ AND MUCH OF NM... ...Synopsis... A series of shortwave troughs are expected to move through the broadly cyclonic flow extending from central Canada across much of the western CONUS. The strongest of these shortwave trough will move from the Pacific Northwest southeastward into the Great Basin while a more subtle shortwave trough moves quickly across Southwest and into the central Plains. At the surface, low initially over central OK is expected to drift eastward while weakening and cyclogenesis is likely during the late afternoon across southeast CO/northeast NM. A dryline will likely extend southeastward from this low to another weak low in northwest TX, continuing southward from this secondary low southwestward into the Edwards Plateau. ...Southwest... Very dry conditions are expected behind the dryline mentioned in the synopsis as a deep mixing within the antecedent airmass supports afternoon RH values in the single-digits from eastern AZ across much of NM. Additionally, the shortwave trough moving through the region will enhanced mid-level flow, which, when combined with deep boundary-layer mixing and a tight surface pressure gradient, will support gusty westerly winds. Sustained winds from 20-30 mph are anticipated with higher gusts. Given the persistent dry conditions across the region, fuels will likely be receptive to fire spread and the resulting combination of favorable fire weather conditions and dry fuels will support a critical fire weather threat. ..Mosier.. 05/25/2017 ...Please see www.spc.noaa.gov/fire for graphic product...
