ZCZC SPCFWDDY2 ALL FNUS22 KWNS 280750 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0250 AM CDT Tue Mar 28 2017 Valid 291200Z - 301200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHWEST TX... ...Synopsis... A deep midlevel cyclone and attendant surface cyclone are forecast to move across portions of the South-Central States. A deep/dry boundary layer west of a merged Pacific front/dryline, extending to the south of the surface cyclone, will linger across southwest TX. More substantial cold advection will occur behind a stronger cold front advancing southward across the southern High Plains. ...Portions of the Southwest States to southwest TX... Across the Critical area encompassing portions of southwest TX, downslope trajectories emanating from the higher terrain of northwest Mexico will support warming/drying of the boundary layer. Minimum RH around 8-15 percent is expected. As vertical mixing diurnally strengthens amid enhanced flow aloft surrounding the deep midlevel cyclone, westerly to west-northwesterly surface winds of 20-25 mph are forecast to combine with the aforementioned low RH amid dry fuels. Winds will turn more northwesterly/northerly through the afternoon/evening behind the southward-moving front. Surrounding the Critical area, elevated fire-weather conditions are anticipated from portions of southeast AZ to southwest TX. Despite areas of strong winds across portions of southwest TX to the north and east of the Critical area, RH is not expected to become sufficiently low for Critical designation. ..Cohen.. 03/28/2017 ...Please see www.spc.noaa.gov/fire for graphic product...
