DISCUSSION...
FRONTAL BOUNDARY HAS NOW PUSHED PAST GALVESTON AND IS MAKING ITS
WAY OFF THE COAST. NORTH WIND BEHIND THE FRONT HAS ALLOWED
SLIGHTLY LOWER DEW POINT AIR TO ADVECT INTO THE REGION. THIS MEANS
A COOLER NIGHT THAN USUAL FOR THIS TIME OF YEAR. TOMORROW AFTERNOON
HIGHS WILL ALSO BE COOLER THAN NORMAL THANKS TO LOWER 850
TEMPERATURES. IN OUR NORTHERN AREAS 850 TEMPS AROUND 16C ARE
FORECASTED WITH 850 TEMPERATURES NEAR 18C TOWARDS OUR
SOUTHWESTERN ZONES. THIS WILL TRANSLATE TO TEMPS IN THE UPPER 80S
TO NEAR 90 FOR MOST OF THE AREA WITH LOWER 90S IN OUR SOUTHWESTERN
AREAS. HAVE ADJUSTED MAX TEMP GRIDS TO MATCH ABOVE. PRECIPITATION
CHANCES LOOK LOW TOMORROW AS MUCH DRIER PWAT AIR FILTERS INTO THE
AREA. YESTERDAY OBSERVED VALUES WERE AROUND 2.2" WITH VALUES
TOMORROW FORECASTED TO FALL NEAR 1.50". GPS MET SITE ALREADY
SHOWING HOUSTON PWAT VALUE DOWN TO 1.6" AT THIS HOUR. 23
