.DISCUSSION...
SHORTWAVE OVER WCNTL TX SHOULD CONTINUE DROPPING SOUTHWARD AND
EVENTUALLY BECOME THE SRN PORTION OF A H5 TROUGH AXIS STRETCHING
FROM THE GREAT LAKES INTO SOUTH TX. THIS TROF WILL LIKELY REMAIN
IN THE VICINITY FOR MUCH OF THE WEEK.

RADAR IS CURRENTLY PICKING UP SOME LIGHT RETURNS NW OF THE CWA &
WOULDN`T BE OVERLY SURPRISED IF A FEW LOCATIONS SEE A COUPLE OF
DROPS TODAY...BUT SUSPECT DRIER LLVLS WILL KEEP MEASURABLE AMOUNTS
AT A MINIMUM. SAME GOES FOR NEAR THE COAST REGARDING SEABREEZE
POTENTIAL. GOES SOUNDER IMAGERY STILL SHOWING THE HIGHER PW`S
CONFINED OFFSHORE.

GUIDANCE SUGGESTS HIGHER MOISTURE LEVELS GRADUALLY RETURN BACK
INLAND LATE MONDAY INTO MIDWEEK...PROVIDING THE BETTER CHANCES OF
RAIN ESP TUE & WED. ALTHOUGH DAYTIME HEATING/SEABREEZE WILL
MAINTAIN SLT CHC/CHC POPS BEYOND THEN...OVERALL CHANCES SHOULD
DIMINISH DURING THE SECOND HALF OF THE WEEK AS THE TROF AXIS
MEANDERS EASTWARD. STILL SOME UNCERTAINTY AS TO IF/WHEN THIS SHIFT
OCCURS AS MEDIUM RANGE MODELS CONTINUE TO HAVE DIFFERING OPINIONS
ON ITS EVOLUTION. 47

&&

.MARINE...
NOT A LOT OF CHANGES WITH THE UPCOMING FCST AS HIGH PRESSURE TO THE
EAST HELPS TO MAINTAIN MAINLY LIGHT (TO OCCASIONALLY MODERATE) S/SE
WINDS OVER THE COASTAL WATERS THRU MUCH OF THIS WEEK. A BROAD UPPER
LEVEL DISTURBANCE DEVELOPING OVER THE REGION WILL PROVIDE SOME SUP-
PORT FOR ISO/WIDELY SCT STORMS DURING THIS SAME TIME FRAME AS WELL.

.AVIATION...
LOW-LEVEL MOISTURE HAS BEEN A BIT SLOWER TO RETURN TO SE TX BUT WE
ARE SEEING ENOUGH DEWPOINT INCREASES TO SUPPORT THE DEVELOPMENT OF
SOME PATCHY BR THIS MORNING...PARTICULARLY FOR THE MORE SRN SITES.
MVFR VIS SHOULD BE A BIT MORE WIDESPREAD TOMORROW MORNING. 41
