SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0951 AM CST Wed Mar 07 2018 Valid 071700Z - 081200Z Elevated conditions will continue for a few hours today across parts of northeast NM into parts of the OK/TX Panhandles. Latest model guidance suggests wind speeds will decrease by mid to late afternoon, but very dry conditions will persist. Elevated conditions also are expected across parts of northeast FL and southeast GA. ..Leitman.. 03/07/2018 .PREV DISCUSSION... /ISSUED 0134 AM CST Wed Mar 07 2018/ ...Synopsis... A highly amplified deep-layer trough located over the eastern U.S. will remain quasi-stationary throughout the forecast period, while an upper-level ridge builds into the Intermountain West. Enhanced mid-level flow of 70-80 kt will be present in the base of the trough. At the surface, a cold front exiting the East Coast will usher in breezy northwesterly winds across most of the Southeast. Farther west, high pressure will settle into the Central/Southern Plains, with southwesterly winds developing across the southern High Plains. ...Portions of New Mexico/TX Panhandle... A dry airmass remains present over the region, where fuels are conducive for large-fire spread in the presence of severe/extreme drought conditions. Afternoon temperatures should warm into the 60s, while RH values fall into the 10-20% range (with localized areas falling into the single digits). Sustained surface winds of 10-15 mph, with gusts of 20-25 mph, should develop during the afternoon hours, leading the elevated fire-weather conditions. ...Portions of Northeast Florida/Southeast Georgia... Limited rainfall from the passing cold front and associated convection has yielded a small region where elevated fire-weather conditions may develop this afternoon. RH values should fall below 30% in the presence of sustained northwesterly winds of 10-15 mph, gusting to near 20 mph, and dry/supportive fuels. ...Please see www.spc.noaa.gov/fire for graphic product...
