Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1257 AM CDT Thu Apr 27 2017 Valid 271200Z - 281200Z ...CRITICAL FIRE WEATHER AREA FOR FAR SOUTHEAST AZ INTO MUCH OF SOUTHERN AND CENTRAL NM AND FAR WEST TX... ...Synopsis... Strong deep-layer west/northwesterly flow will persist across much of the southwestern states to the southern Plains. Lee surface cyclogenesis will develop during the late morning into the afternoon over the central and southern High Plains, while higher surface pressure resides near/just offshore the Pacific coast. This will result in at least a modest pressure gradient across AZ/NM and into TX, aiding in strong surface winds. Warm and dry conditions also will continue and another day of elevated to critical conditions is expected. Dry conditions are also expected to continue over parts of central FL as temperatures warm into the 90s during the afternoon. Given ongoing drought and dry fuel conditions across this area, elevated fire weather conditions are expected. ...Much of AZ/NM into far west TX... Temperatures will warm into the 80s and low 90s across southern AZ/NM into west TX with cooler temperatures with northward extent. RH values will fall into the 10-15 percent range across the critical area from southeast AZ into parts of southern/central NM and far west TX. In the surrounding elevated across parts of northern AZ/NM into the TX Panhandle southward to the Concho Valley, RH values will be a bit more marginal from 15-20 percent. As for winds, westerly surface winds will quickly increase during the late morning. Sustained winds 20-30 mph with higher gusts are possible in the critical area and northern portions of the elevated area. Wind speeds may be somewhat weaker over western portions and southeastern portions of the elevated. The eastward extent of the critical will be modulated by unfavorable fuel conditions due to ongoing springtime green-up across much of western TX. ...East-Central FL Peninsula... Drying is expected as temperatures warm into the low 90s and deep boundary-layer mixing ensues. RH values generally around 30-35 percent are expected with ongoing drought conditions in place. The main limiting factor will be generally light southwesterly winds at 10 mph or less. Given marginal RH values and ongoing drought, elevated fire weather potential exists. ..Leitman.. 04/27/2017 ...Please see http://ift.tt/2i2um2s for graphic product...Read more
