THROUGH NEXT WEEK...
A BRIEF HIATUS/REPRIEVE/VACATION/MERCY FROM THE OPPRESSIVE HEAT WE
EXPERIENCED THROUGH MUCH OF JULY IS SLOWLY ENDING, AT LEAST TO SOME
MEASURE, AS HEAT AND HUMIDITY INCREASES THROUGH THE WEEKEND INTO
NEXT WEEK. A "LIMITED" RISK FOR HEAT IS IN PLACE THROUGH AT LEAST
EARLY NEXT WEEK FOR MUCH OF THE AREA GENERALLY WEST OF I-55 AS HEAT
INDICES CREEP UP ACCOMPANIED BY MUCH DEEPER MOISTURE OF TROPICAL
ORIGIN. MAXIMUM HEAT INDICES IN THAT OUTLOOK AREA WILL APPROACH 105
F EACH AFTERNOON THROUGH THE WEEKEND AND LIKELY WELL INTO NEXT WEEK.
FOR THE MOMENT, HOWEVER, THIS INCREASE IN HEAT APPEARS TO ONLY BE
SLIGHTLY ABOVE CLIMATOLOGICAL NORMALS FOR MID AUGUST AND WHILE
CAUTION SHOULD BE EXERCISED IT DOES NOT APPEAR TO BE AS OPPRESSIVE
AS THE LAST ROUND OF HEAT (AT LEAST THROUGH THE NEXT WEEK).
RAIN CHANCES WILL BE ON THE RISE ALONGSIDE THE MOISTURE INCREASES
AND WE'LL SEE A RETURN TO SCATTERED SHOWERS AND STORMS PARTICULARLY
BY SUNDAY WHEN CHANCES WILL LIKELY RANGE FROM AROUND 30% NEAR HIGHWAY
82 TO AROUND 50% ALONG HIGHWAY 84. ORGANIZED STRONG TO SEVERE STORMS
AREN'T EXPECTED WITH ENVIRONMENTAL SHEAR QUITE (SEASONABLY) LOW BUT
DIURNAL INSTABILITY AND DEEP LAYER MOISTURE COULD ALLOW FOR A BRIEF
GUSTY/STRONG STORM OR TWO AS THUNDERSTORM CORES COLLAPSE.
THERE IS LITTLE REASON TO SUSPECT MUCH DEVIATION FROM THIS PATTERN AS
WE HEAD INTO LATE NEXT WEEK THOUGH TRENDS WILL BE MONITORED TO SEE
EXACTLY HOW WARM WE MIGHT GET.
TROPICS BECAME MORE ACTIVE OVERALL OVER THE LAST WEEK OR SO AND THIS
BURST OF ACTIVITY IS LIKELY TO CONTINUE ACROSS THE TROPICAL
ATLANTIC. SOME LONGER-TERM GUIDANCE HAS HINTED AT THE POSSIBILITY
FOR ROBUST DEVELOPMENT FROM AN AFRICAN EASTERLY WAVE (AEW). HOWEVER,
IT IS NOW THE PEAK OF HURRICANE SEASON AND IT DOESN'T TAKE INTENSE
DYNAMICAL GUIDANCE TO SURMISE A STORM COULD BE POSSIBLE SOMEWHERE IN
THE ATLANTIC OCEAN IN MID AUGUST. REGARDLESS, THERE REMAINS NO CAUSE
FOR ALARM AND ONLY NORMAL, SEASONAL PREPAREDNESS/CAUTION IS
NECESSARY. /86/
