DISCUSSION

WATER VAPOR IMAGERY SHOWS THE MID-UPPER TROF AXIS CROSSING OVER THE
SABINE AND INTO LOUISIANA. AS IT CONTINUES ITS EASTWARD PROGRESS,
THE FLOW ALOFT WILL TRANSITION TO A DRIER NORTHWESTERLY DIRECTION
AS RIDGING TO OUR WEST GRADUALLY MOVES IN OUR DIRECTION INTO
MIDWEEK. DRY, MOSTLY SEASONABLE WX CAN BE EXPECTED THE NEXT
SEVERAL DAYS, THOUGH DAYTIME HIGHS WILL PROBABLY TREND ABOUT 3-5F
ABOVE NORMS WITH THE LOWER PW AIR (<1") FILTERING IN.
HEADING INTO THE LATE WORK WEEK, SURFACE HIGH PRESSURE WILL BE
MOVING OFF TO THE EAST AND WE'LL SEE A RETURN TO A MORE DOMINATE SSE
LLVL WIND COMING IN OFF THE GULF. THIS WILL BRING ALONG SOME HIGHER
DEWPOINTS/RH'S, CLOUD COVER, AND WARMER OVERNIGHT LOW TEMPS.
MID-UPPER RIDGING WEAKENS AND TRACKS TO OUR EAST OVER THE WEEKEND. A
STRENGTHENING SOUTHERLY LOW LEVEL FLOW WILL DRIVE PW'S BACK UP INTO
THE 1.5-1.8" TERRITORY, BUT WITH THE LACK OF SIGNIFICANT FORCING OR
WEATHER SYSTEMS IN THE VICINITY THIS WEEKEND, RAIN CHANCES WILL
PROBABLY BE LIMITED TO SOME ISOLATED DIURNALLY DRIVEN SHOWERS OR
STREAMER SHOWERS. POSSIBLY SOME BETTER CHANCES ARRIVING LATE MONDAY
OR TUESDAY IN ASSOCIATION WITH SOME WEAK TROFFINESS MOVING ACROSS
THE SOUTHERN PLAINS. 47

VFR CONDITIONS WILL PREVAIL THROUGHOUT THE TAF PERIOD WITH ONE
POTENTIAL EXCEPTION. SOME MODEL GUIDANCE IS HINTING AT A BRIEF
WINDOW FOR REDUCED VISIBILITIES AT THE NORTHERN THREE TERMINALS
BETWEEN 11Z-14Z. DRIER AIR WILL BE MOVING IN, BUT MODEL SOUNDINGS
AND LOW DEWPOINT DEPRESSIONS ARE SUPPORTIVE OF A BRIEF PATCHY FOG
WINDOW EARLY TUESDAY MORNING. CONFIDENCE IS LEANING MORE TOWARDS
THE LOW TO MODERATE SIDE, SO COVERED THIS WITH A SHORT TEMPO FOR
CLL/UTS/CXO. OUTSIDE OF THAT, MAINLY A WIND FORECAST. BREEZY
NORTHERLY TO NORTHEASTERLY WINDS LATE THIS AFTERNOON WILL BECOME
LIGHT AND VARIABLE OVERNIGHT, THEN PICK UP AGAIN OUT OF THE

MODERATE NORTHEAST WINDS WILL DIMINISH AS THE DAY PROGRESSES TUESDAY
AS HIGH PRESSURE SETTLES IN ACROSS THE AREA. WE WILL PROBABLY SEE A
LATE AFTERNOON AND EVENING SEABREEZE (SE WINDS). WIND REGIME INTO
THURSDAY WILL BE DOMINATED BY THE LANDBREEZE (LIGHT OFFSHORE WINDS
LATE AT NIGHT AND IN THE MORNINGS) AND SEABREEZE (ONSHORE WINDS IN
THE AFTERNOON AND EVENING). A TIGHTENING PRESSURE GRADIENT WILL LEAD
TO INCREASING SOUTHERLY WINDS AND BUILDING SEAS HEADING INTO THE
WEEKEND. 47
