SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0956 AM CST Sat Feb 24 2018 Valid 241700Z - 251200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN HIGH PLAINS... The ongoing forecast is on track with only minimal changes needed to the elevated area in the Texas Panhandle. Elevated to critical fire weather conditions are expected across a broad area of eastern New Mexico and the western third of Texas today, although the driest fuels and most favorable conditions for fire spread remain confined to the critical area from east-central New Mexico eastward into portions of the Texas South Plains/Panhandle. See the previous forecast discussion below for more information. ..Cook.. 02/24/2018 .PREV DISCUSSION... /ISSUED 0156 AM CST Sat Feb 24 2018/ ...Synopsis... An upper shortwave trough over the central/southern Rockies this morning will lift northeast to the Great Lakes through the end of the period. As this occurs, another shortwave trough will track southeast from the Pacific Northwest toward the Four Corners by Sunday morning. This will result in continued strong deep-layer west/southwesterly flow across the southern Rockies and adjacent Plains. At the surface, a weak low will develop in the vicinity of the eastern TX Panhandle/western OK and a tight pressure gradient will overlay the southern Rockies into the High Plains. This will aid in strong downslope westerly winds across southeast CO and eastern NM into western TX. Sustained wind speeds around 15-25 mph with higher gusts are expected across the region. RH values will fall into the 8-20 percent range, with the lowest values across parts of eastern NM into western TX. It is this area from east-central NM into the TX South Plains where critical fire weather conditions are possible given an overlap with very dry fuels. A broader area of elevated fire weather potential will extend from southeast CO southward toward the TX Big Bend. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
