####018001570#### FNUS22 KWNS 210733 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0232 AM CDT Sun Mar 21 2021 Valid 221200Z - 231200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF WEST TEXAS AND SOUTHERN NEW MEXICO... ...Synopsis... Mid-level flow will amplify further across the southern Rockies/High Plains as a mid-level low initially over the Four Corners reaches the High Plains through the end of the forecast period. As this occurs, surface troughing/cyclogenesis will become more pronounced across the Texas South Plains and vicinity, with very dry and windy conditions west of the trough and increasingly moist air east of the trough. Fire-weather concerns will increase considerably west of the trough. ...Southern Rockies/Plains... The combination of increasing flow aloft and a steepening surface pressure gradient will increase surface winds into the 30-40 mph range across a broad corridor extending from southwestern New Mexico to the Texas South Plains. This flow will occur within an extremely dry airmass characterized by 60s F surface temperatures and RH values below 10% - lowest in southeastern New Mexico and adjacent areas of west Texas. These conditions flirt with extremely critical thresholds in a few areas, with the only lingering concern being fuel states and modest ERCs. Nevertheless, large and rapidly spreading fires are possible where ignitions occur. ..Cook.. 03/21/2021 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018001535#### FNUS21 KWNS 210733 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0232 AM CDT Sun Mar 21 2021 Valid 211200Z - 221200Z ...CRITICAL FIRE WEATHER AREA FOR SOUTHWESTERN INTO CENTRAL NEW MEXICO... ...Synopsis... A positive-tilt trough will sharpen across the Desert Southwest today while migrating southeastward toward the southern Rockies. This wave will amplify flow aloft downstream into the 40-70 kt range. Meanwhile at the surface, a low will organize very near the New Mexico/Texas border region. The synoptic setup will foster areas of elevated to critical fire-weather conditions across the southern Rockies and High Plains. ...Eastern Arizona through western New Mexico... Models continue to agree that a broad swath of westerly low-level flow will develop during peak heating hours across the region. Speeds of 15-25 mph will become common - locally higher across southern and western New Mexico. Meanwhile, a pre-existing dry airmass will help RH values to lower into the 12-25% range in most areas - locally lower from southwestern into central New Mexico. A critical delineation has been introduced where confidence is highest that several hours of critically low RH values will coexist with 20+ mph surface winds. Surrounding this delineation, critical fire weather may be observed for brief periods throughout the afternoon. ..Cook.. 03/21/2021 ...Please see www.spc.noaa.gov/fire for graphic product... $$
