   ...CRITICAL FIRE WEATHER AREA FOR FAR SOUTHEASTERN ARIZONA INTO MUCH
   OF SOUTHERN AND CENTRAL NEW MEXICO AND FAR WEST TEXAS...

   No changes have been made to the ongoing elevated/critical areas.
   See the previous discussion below for more information.

   .PREV DISCUSSION... /ISSUED 1257 AM CDT Thu Apr 27 2017/

   ...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.
