####018002106#### FNUS22 KWNS 090752 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0151 AM CST Tue Mar 09 2021 Valid 101200Z - 111200Z ...CRITICAL FIRE WEATHER AREA FOR SOUTHERN HIGH PLAINS... ...Synopsis... A belt of stronger 60-85 mph upper-level flow is forecast to overspread the southern Rockies/High Plains Wednesday as a broad upper-level trough, currently situated off the West Coast, progresses inland. While the residual lee trough from Tuesday may migrate eastward early in the day, surface pressure falls along the lee of the Rockies will anchor the trough over the CO/KS border southward along the TX/NM border. Strengthening winds along this axis will promote widespread elevated to critical fire weather conditions over a region with dry fine fuels. ...Southern High Plains... Widespread critical fire weather conditions remain likely from southwest NM into eastern NM and the OK/TX Panhandles. Guidance continues to show high probabilities of widespread southwesterly winds between 20-30 mph across this region with wind gusts upwards of 40-45 mph possible amid strong mid-level flow within a deeply mixed boundary layer. Relative Humidity values between 10-15% remain likely and may fall as low as the single digits for portions of eastern NM. Nocturnal RH values in the teens observed upstream across southern AZ, as well as expected low-level trajectories emanating from the southern Rockies, give credence to this forecast. Elevated conditions are expected on the periphery of the critical risk area, and are possible as far north/northeast as east-central CO and western KS in the wake of the departing surface low, though confidence in the RH forecast is somewhat low for this region. Although larger fuels are only modestly receptive per recent fuel analyses, several grass fires in recent days across this region confirm that fine fuels are receptive and will support a wildfire threat. ..Moore.. 03/09/2021 ...Please see www.spc.noaa.gov/fire for graphic product... $$
