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
