MID/UPPER WATER VAPOR IMAGERY SHOW A CLEAR CLOCKWISE CIRCULATION
IN THE VICINITY OF LOUISIANA. THIS CIRCULATION IS INDICATIVE OF A
MID/UPPER RIDGE THAT WILL DOMINATE SE TEXAS WEATHER THROUGH THE
END OF THE WEEK. THE RIDGE IS EXPECTED TO BUILD AS MID-LEVEL DRY
AIR INCREASES, THANKS IN PART TO THE MUCH SPOKEN ABOUT SAHARAN
DUST IN THE MID-LEVELS. I SAY "IN PART" BECAUSE THE DUST SIGNAL ON
SATELLITE IMAGERY ISN'T PARTICULARLY STRONG. BUT THERE IS DRY AIR
IN THE MID-LEVELS WORKING ITS WAY INTO THE REGION. THE ATMOSPHERE
IS NOT EXPECTED TO BE EXTREMELY SUPPRESSIVE TODAY. THEREFORE, WE
HAVE KEPT WIDELY SCATTERED SHOWERS/THUNDERSTORMS IN THE FORECAST.
THAT BEING SAID, MONDAY POPS HAVE TRENDED DOWN SOMEWHAT COMPARED
TO WHERE THEY WERE 24 HOURS AGO. THIS TREND CAN BE SEEN THROUGH
THE FORECAST PERIOD, WITH DAILY POPS THIS WEEK DROPPING A SOLID 10
PERCENTAGE POINTS SINCE YESTERDAY. WE COULD STILL SEE ISOLATED
ACTIVITY ALONG THE SEA BREEZE BOUNDARY TUESDAY THROUGH THE END OF
THE WEEK. BUT MOST AREAS ARE EXPECTED TO REMAIN DRY. REGARDING
TEMPERATURES, EXPECT THE FURNACE TO DIAL UP A FEW NOTCHES.
AFTERNOON INLAND HIGH TEMPERATURES ARE EXPECTED TO BE IN THE MID
TO UPPER 90S MUCH OF THIS WEEK. BY THE END OF THE WEEK, I EVEN
SEE A FEW 100 DEGREE PIXELS IN OUR TEMPERATURE GRIDS. AND OF
COURSE, IT WOULDN'T BE SOUTHEAST TEXAS WITHOUT HUMIDITY. SO EXPECT
CONDITIONS TO FEEL HOTTER THAN THE THERMOMETER SUGGESTS. ONE
SILVER LINING IS THAT CONDITIONS MAY BECOME BREEZIER LATER IN THE
WEEK. IN ADDITION, AFTERNOON DEW POINTS MAY MIX DOWN TO LOWER
VALUES, HELPING WITH THE HUMIDITY BY WEDNESDAY AND BEYOND. SO
LET'S HOPE FOR THAT BREEZE AND THE SLIGHTLY LOWER HUMIDITY TO HELP
TAKE THE EDGE OFF THE HEAT. REGARDLESS, PRACTICING HEAT SAFETY
WILL BE A MUST ALL WEEK. CAUSE EVEN NORMAL JULY HEAT CAN BE QUITE
HAZARDOUS.

VFR CONDITIONS WITH SSE WINDS WILL PERSIST THROUGH THE PERIOD WITH
THE WINDS AROUND 8-12KT DURING THE DAYTIME HOURS AND DROPPING DOWN
TO BELOW 6KT OVERNIGHT. THE SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS THAT DEVELOPED THIS AFTERNOON HAVE COME TO AN END,
AND ADDITIONAL ACTIVITY IS EXPECTED TO REDEVELOP MONDAY AFTERNOON.
HOWEVER, DRIER AIR IN PLACE WILL LIKELY KEEP THE COVERAGE LESS
COMPARED TO THE PAST FEW DAYS.

ISOLATED TO WIDELY SCATTERED SHOWERS AND THUNDERSTORMS ARE
POSSIBLE AGAIN ON MONDAY. THE ENHANCED SWELL EXPERIENCED OFFSHORE

WEEK IS EXPECTED TO FEATURE LIGHT TO MODERATE ONSHORE WINDS AND 2
TO 4 FOOT SEAS. ISOLATED SHOWER AND THUNDERSTORM ACTIVITY CANNOT
BE RULED OUT ALONG THE SEA BREEZE BOUNDARY NEAR THE COAST DURING
THE LATE MORNING AND AFTERNOON HOURS. ISOLATED ACTIVITY CANNOT BE
RULED OUT OVERNIGHT AND DURING THE EARLY MORNING HOURS OVER THE
GULF. BUT GENERALLY SPEAKING, RAIN CHANCES ARE LOW AND
TEMPERATURES WILL BE HIGH.
