.DISCUSSION...SURFACE ANALYSIS THIS EVENING SHOWS THE SURFACE LOW
AROUND KELD WITH THE COLD FRONT STRETCHING TO SOUTHEAST TX...AND THIS

OVER THE REMAINDER OF THE CWFA. THEN AFTER MIDNIGHT EXPECT SHOWER
ACTIVITY TO MAINLY BE LIMITED TO THE SOUTHEAST. IT STILL LOOKS LIKE
FOG WILL BE POSSIBLE OVERNIGHT WITH MOIST GROUNDS AND MANY LOCATIONS
ALREADY SEEING CALM WINDS. SO WILL KEEP THAT WORDING IN THE GRIDS AS
WELL.

SOME TEMPERATURES ACROSS THE ARKLAMISS REGION...ESPECIALLY IN THE
SOUTH HAVE ALREADY DIPPED BELOW THE ORIGINAL FORECAST LOW. SO HAVE
ADJUSTED LOW TEMPERATURES DOWN FOR SEVERAL LOCATIONS. HAVE ADJUSTED
HOURLY TEMPERATURES ACCORDINGLY.

HOURS. CONDITIONS SHOULD BEGIN TO IMPROVE AFTER SUNRISE...GIVING VFR
