AN UPPER-LEVEL TROUGH ACROSS THE WESTERN GULF, ALONG WITH A SECOND
TROUGH ACROSS THE CENTRAL GULF, WILL SUPPORT AN UNSETTLED WEATHER
PATTERN THROUGH MUCH OF THE WORK WEEK ACROSS THE ARKLATEX.
INSTABILITY ASSOCIATED WITH THE TWO UPPER-LEVEL DISTURBANCES WILL
ALLOW FOR INCREASED CLOUD COVER, LIMITING AFTERNOON HIGH
TEMPERATURES TO THE LOWER TO MIDDLE 90S THROUGH THE WEEK, AS WELL AS
BRINGING INCREASED CHANCES FOR AFTERNOON SHOWERS AND THUNDERSTORMS
EACH DAY.
THE HIGHEST RAIN CHANCES WILL BE FROM TUESDAY THROUGH WEDNESDAY,
MAINLY ACROSS NORTH LOUISIANA AND SOUTH ARKANSAS AS THE CENTRAL GULF
DISTURBANCE MOVES INLAND INTO SOUTH LOUISIANA AND MISSISSIPPI.
DESPITE THE DISTURBANCE MOVING NORTH INTO THE OHIO RIVER VALLEY BY
THURSDAY, RAIN CHANCES WILL NOT COMPLETELY DIMINISH ACROSS THE
ARKLATEX DUE TO THE WEST GULF TROUGH EXPANDING AND LINGERING ACROSS
NORTH TEXAS INTO OKLAHOMA THROUGH LATE WEEK.
AN UPPER-LEVEL RIDGE TO BUILD WEST ACROSS THE NORTHERN GULF COAST
ALLOWING FOR GRADUAL WARMING ACROSS LOUISIANA AND ARKANSAS ON FRIDAY
AND SATURDAY WITH AFTERNOON HIGHS FORECAST TO CLIMB INTO THE MID
90S.
OTHERWISE, SURFACE HIGH PRESSURE TO THE EAST WILL ALLOW FOR
CONTINUED MOIST SOUTHERLY FLOW ACROSS THE ARKLATEX MAINTAINING
DEWPOINT VALUES IN THE LOW TO MID 70S THROUGH THE PERIOD. /05/
