SURFACE ANALYSIS REVEALS A COLD FRONT DRAPED ACROSS THE SOUTHERN
HALF OF THE CWA. SHOWERS AND THUNDERSTORMS HAVE BEEN ONGOING
THROUGH MUCH OF THE EVENING TO THE SOUTH OF THIS BOUNDARY.
LOOKING OUT TO OUR WEST, ANOTHER MCS IS RIDING ALONG THE FRONT,
MOVING THROUGH THE ARKLATEX REGION. LATEST CAMS CONTINUE TO HINT
AT THIS ACTIVITY FIZZLING OUT BEFORE MAKING IT TO ALABAMA. WE
WILL NEED TO KEEP AN EYE OUT FOR CONVECTIVE DEVELOPMENT ALONG ANY
OUTFLOW BOUNDARIES THIS SYSTEM SENDS INTO OUR AREA. ANOTHER H5
SHORTWAVE WILL ROTATE ALONG THE EASTERN PERIPHERY OF THE RIDGE TO
OUR WEST, MOVING ACROSS THE SOUTHERN HALF OF THE STATE. THIS
SHOULD HELP SUPPORT ANY CONVECTIVE ACTIVITY THAT IS ABLE TO
DEVELOP. ANY STORMS THAT DEVELOP WILL BE ABLE TO TAP INTO A MOIST
AIRMASS, ALLOWING FOR BRIEF PERIODS OF HEAVY RAINFALL. WPC
MAINTAINS A SLIGHT RISK (LEVEL 2 OF 4) FOR EXCESSIVE RAINFALL FOR
OUR SOUTHWESTERN COUNTIES TOMORROW. ADDITIONAL DEVELOPMENT IS
LIKELY ON THURSDAY AS THE UPPER LEVEL IMPULSE SLOWLY EXITS THE
REGION.
BY THE WEEKEND, UPPER LEVEL RIDGING TAKES CONTROL, BRINGING DRIER
AND WARMER CONDITIONS TO THE REGION. IF ANY SHOWERS OR STORMS
DEVELOP, THEY WILL BE MAINLY DIURNALLY DRIVEN. TEMPERATURES WILL
WARM OVER THE WEEKEND INTO EARLY NEXT WEEK WITH HIGHS IN THE LOW
TO MID 90S AND HEAT INDICES FROM 100-105 DEGREES. THIS WILL POSE
A MODERATE TO MAJOR HEAT RISK OVER THE MAJORITY OF THE REGION.
