THE DOG DAYS OF SUMMER ARE UPON US AND THE WEATHER
PATTERN SEEMS TO HAVE GOTTEN THE MESSAGE AS A PERSISTENT AND
SOMEWHAT STAGNANT WEATHER PATTERN IS EXPECTED TO CONTINUE THROUGH
THE WEEK. THE AREA WILL REMAIN SANDWICHED BETWEEN A SPRAWLING UPPER
LEVEL RIDGE THAT CONTINUES TO BAKE THE SOUTHWESTERN U.S. AND AN
UPPER LEVEL LOW CENTERED OVER THE SOUTHEASTERN U.S. THE RESULTING
WEAK GRADIENT ALOFT WILL ALLOW FOR DAILY, DIURNALLY DRIVEN AFTERNOON
THUNDERSTORMS (20-40% CHANCE). ANY STORMS THAT DEVELOP WILL LIKELY
HAVE LITTLE FORWARD MOTION AND WILL, INSTEAD, BE PROPAGATED BY
OUTFLOW BOUNDARIES AND THE DAILY SEA BREEZE. AT THE SURFACE, WEAK
HIGH PRESSURE OVER THE CENTRAL AND EASTERN GULF WILL MAINTAIN LIGHT
SOUTHERLY WINDS THROUGH THE WEEKEND. TEMPERATURES WILL REMAIN NEAR
SEASONAL NORMALS WITH AFTERNOON HIGHS CLIMBING INTO THE LOW TO MID
90S EACH DAY WITH MAXIMUM HEAT INDICES RANGING FROM 101-109.
