THROUGH THE WEEKEND...
WARMING TEMPERATURES ALONG WITH INCREASES IN HUMIDITY BOTH NEAR THE
SURFACE AND THROUGH THE COLUMN WILL CONTINUE TO RESULT IN INCREASED
HEAT STRESS CONCERNS AS WELL AS INCREASED RAIN CHANCES THROUGH THE
WEEK. AS THE WESTERN GULF UPPER LOW CONTINUES TO WEAKEN AND SLIDE
WEST AWAY, WE REMAIN UNDER THE INFLUENCE OF GENERAL DEEP LAYER
RIDGING AND THAT WILL LIKELY BE THE CASE THROUGH THE NEXT WEEK. HEAT
CONCERNS GROW FURTHER BY MIDWEEK INTO THE WEEKEND AND TWO SEPARATE
OUTLOOKS FOR HEAT REMAIN IN PLACE, THE FIRST VALID THROUGH THE FIRST
PART OF THE FORECAST PERIOD AND COVERING MUCH OF THE WESTERN PORTION
OF THE ARE IN A "LIMITED" OUTLOOK WITH THE SECOND REACHING FURTHER
EASTWARD AND INTRODUCING SOME POCKETS OF "ELEVATED" RISK. WHILE HEAT
INDICES NEAR 105 F WILL BE MOST COMMON, THE AREAS OF HIGHLIGHTED
HIGHER RISK COULD SEE MAXIMUM HEAT INDICES RISE IN TO THE 105-115 F
RANGES. HEAT STRESS WILL LIKELY BE THE DOMINANT HAZARD CONCERN
THROUGH THE PERIOD. HEAT PRODUCTS (ADVISORIES/WARNINGS) COULD BE
NECESSARY LATER THIS WEEK.
OTHERWISE, SCATTERED MOSTLY DIURNAL SHOWERS AND A FEW THUNDERSTORMS
WITH OCCASIONALLY GUSTY WINDS WILL BE POSSIBLE EACH AFTERNOON.
DRIVEN PRIMARILY BY INSTABILITY AMID QUITE LIMITED SHEAR/FORCING,
ORGANIZED SEVERE STORMS ARE NOT EXPECTED THOUGH A BRIEF STRONG GUST
OR TWO COULD BE POSSIBLE ASSOCIATED WITH ANY STRONGER CORE THAT
MANAGES TO DEVELOP. RAIN CHANCES WILL BE LARGELY IN THE 20-40%
CHANCE RANGE THROUGH TOMORROW BUT INCREASE TO THE 40-70% RANGES BY
MID WEEK. IN GENERAL, SOUTHERN PORTIONS OF THE AREA WILL SEE THE
BEST DAILY RAIN CHANCES AS POTENTIALLY AIDED BY SEABREEZE AFFECTS AS
WELL AS SOMEWHAT LOCALLY HIGHER DEEP LAYER MOISTURE. /86/
