.UPDATE...
A MINOR UPDATE IS BEING SENT TO INCREASE TEMPS THIS AFTERNOON FOR
SOME LOCATIONS...AND LOWER DEWPOINTS.
&&
.DISCUSSION...
THE 12Z MAF SOUNDING INDICATES 25C NEAR THE TOP OF THE INVERSION
THIS MORNING...WITH SW TO W DOWNSLOPE FLOW PRESENT THROUGH THE LOW
TO MID LEVELS. IT IS ALREADY 85F AT MAF THIS MORNING...WHICH IS
2 DEGREES WARMER THAN THE PROJECTED 00Z METMOS. SOME CIRRUS WILL
INITIALLY SLOW HEATING FROM CENTRAL LEA COUNTY THROUGH THE WESTERN
LOW ROLLING PLAINS...BUT THIS DEBRIS WILL NOT REMAIN PRESENT
THROUGH THE AFTERNOON HOURS. WE HAVE RAISED MAX TEMPS FOR THIS
AFTERNOON 1-4 DEGREES FOR MOST LOCATIONS CONSIDERING ALL OF THE
PREVIOUS. CURRENT DEWPOINT TRENDS ALSO SUGGEST VERY DRY AIR WILL
BE IN PLACE FOR MUCH OF THE CWA...ESPECIALLY ACROSS THE BIG BEND
AND DAVIS MOUNTAINS REGION. DEWPOINTS WERE DECREASED BEHIND THE
DRYLINE FOR THIS AFTERNOON. SINCE LOW RH IS ANTICIPATED...HEAT
INDICES WILL NOT EXCEED TEMPERATURES FOR MOST LOCATIONS.
HOWEVER...IT IS EXTREMELY IMPORTANT TO STAY HYDRATED WITH SUCH DRY
CONDITIONS PRESENT. SEEK SHADE AS OFTEN AS POSSIBLE IF STUCK
OUTDOORS. ALL UPDATED PRODUCTS WILL BE SENT SHORTLY.
