Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0156 PM CDT Wed Apr 26 2017 Valid 271200Z - 281200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL/SOUTHERN NEW MEXICO AND FAR WEST TEXAS... No substantial changes have been made to the critical area across parts of central/southern NM and far west TX or to the surrounding elevated area across portions of the Southwest and southern Plains. See the previous discussion below for more information. An elevated area has been introduced for portions of the FL peninsula. A modest strengthening of the surface pressure gradient across FL will occur through Thursday afternoon as a cold front moves across the Southeast. Southerly winds should increase to around 10 mph, locally higher, as RH values fall below 40%. Amidst dry fuels, these meteorological conditions will support an elevated fire weather threat. ..Gleason.. 04/26/2017 .PREV DISCUSSION... /ISSUED 1232 AM CDT Wed Apr 26 2017/ ...Synopsis... The fire weather story remains much the same on Thursday as the previous few days. Strong west/northwesterly deep-layer flow will overspread much of the southern tier of the U.S. as a broad upper trough encompasses the middle of the CONUS. A strengthening surface low over the southern/central High Plains with higher pressure near the Pacific coast will result in a modest pressure gradient across the southwestern states to the southern High Plains. Gusty winds aligned with dry conditions will again lead to elevated to critical fire weather concerns across parts of AZ/NM and western TX. ...Portions of AZ, much of NM into western TX... Fuel conditions continue to add a question mark to the eastern extent of critical delineation. Green-up continues across west TX into the eastern plains of NM. For now, highest confidence in the overlap of strong winds, low RH and at least areas of available fuels has been noted by the critical area across parts of the southern/central NM into far west TX. Here, westerly surface winds 25-35 mph with higher gusts are expected and RH values falling into the 7-15 percent range are expected. These meteorological conditions will spread east into parts of the TX Panhandle and TX South Plains to the Concho Valley, but again, concerns over available fuels will preclude critical delineation here. Further west across parts of northern and eastern AZ into northern NM, winds will be slightly lower and RH values will range from 15-25 percent. Some spotty/brief critical conditions will be possible but less widespread compared to further east. ...Please see http://ift.tt/2i2um2s for graphic product...Read more
