.AVIATION...
ACTIVITY FROM THE NORTH CONTINUING TO EFFECT UTS/CXO AND CLL ATTM
BUT WE ARE ALSO SEEING SOME ISO POP-UPS FROM COLLIDING BOUNDARIES
CLOSER TO I-10 (SEABREEZE AND OUTFLOWS). OF NOTE FOR LATER IN THE
EVENING MAY BE THE STRONG OUTFLOW MOVING IN FROM LCH. NOT SURE IF
THIS IS WHAT MODELS HAD IN MIND (THESE LAST FEW RUNS) IN TERMS OF
PCPN FOR THE OVERNIGHT HRS...BUT DID NOT INCLUDE ANY MENTION WITH
THIS PACKAGE. OTHERWISE MOSTLY VFR CONDITIONS WITH VRB WINDS OVER
THE NRN SITES. 41
&&
.PREV DISCUSSION...
SEEING SOME ISOLATED SHOWERS BEGINNING TO DEVELOP AROUND THE
CROCKETT AND CARLOS AREAS...AND EXPECT SOUTHEAST TEXAS COVERAGE
AND INTENSITY TO INCREASE OVER THE NEXT SEVERAL HOURS AS PEAK
HEATING IS REACHED AND THE SEA BREEZE FRONT BEGINS TO INTERACT
WITH ANY BOUNDARIES CREATED BY THE INLAND STORMS. HEAT INDEX
VALUES ARE GENERALLY IN THE LOWER 100S...AND VALUES AT OR SLIGHTLY
ABOVE 108 ARE STILL POSSIBLE OVER THE NEXT SEVERAL HOURS. ACTIVITY
SHOULD LINGER INTO THE EVENING HOURS... AND SOME MODELS HAVE MORE
STUFF DEVELOP OVERNIGHT GENERALLY FROM THE CORRIGAN AREA TO THE
HOUSTON AREA. LOWER RAIN CHANCES WILL BE CARRIED FOR
TOMORROW...AND EXPECT HEAT INDEX VALUES TO POSSIBLY BE AT OR NEAR
ADVISORY LEVELS FOR ONLY AN HOUR OR TWO AROUND OUR FAR WEST AND
SOUTHWEST COUNTIES. SO WITH THIS PACKAGE OUR HEAT ADVISORY WILL BE
ALLOWED TO EXPIRE THIS EVENING AND NO ADVISORY WILL BE PLANNED FOR
TOMORROW. A COUPLE VERY WARM DAYS SHOULD CLOSE OUT THE WEEK WITH A
MAJORITY OF THE AREA STAYING DRY. THINGS LOOK TO GRADUALLY CHANGE
OVER THE WEEKEND AS OUR AREA BECOMES SANDWICHED BETWEEN UPPER
RIDGING BOTH TO OUR WEST AND TO OUR EAST. THIS WILL ALLOW FOR
INCREASING RAIN CHANCES AND SLIGHTLY COOLER HIGH TEMPERATURES AS
WE CLOSE OUT THE WEEKEND AND HEAD INTO THE FIRST HALF OF NEXT
WEEK. WILL CARRY HIGHER RAIN CHANCES CLOSER TO THE COASTAL
COUNTIES AND ACROSS THE COASTAL WATERS WITH LOWER RAIN CHANCES THE
FURTHER INLAND YOU GO. 42
