KEY MESSAGES
ISSUED AT 137 PM CDT FRI MAR 13 2026
- DRY CONDITIONS WILL CONTINUE THROUGH SATURDAY AHEAD OF
INCREASING RAIN PROSPECTS ON SUNDAY.
- TEMPERATURES WILL CONTINUE TO CLIMB AHEAD OF A STRONG COLD
FRONT LATE SUNDAY AFTERNOON THAT WILL ALLOW FOR A RETURN TO
WELL BELOW NORMAL TEMPERATURES, INCLUDING OVERNIGHT LOWS NEAR
AND BELOW FREEZING BY MONDAY MORNING.
- THE INFLUENCE OF A STRENGTHENING RIDGE OUT WEST WILL LIMIT RAIN
CHANCES THROUGH THE EXTENDED FORECAST, WITH POTENTIAL FOR
ANOTHER PROLONGED DRY STREAK BEYOND THE 7 DAY PERIOD.
DISCUSSION
ISSUED AT 137 PM CDT FRI MAR 13 2026
ANOTHER CLEAR BLUE SKY DAY IS UNFOLDING ACROSS THE FOUR STATE REGION
AS OUR PRESENT WEATHER PATTERN CONTINUES TO FAVOR DRY CONDITIONS
LOCALLY. AT THE SAME TIME, TEMPERATURES HAVE WARMED UP NICELY AFTER
A COOL MORNING IN THE 30'S AND 40'S. UNDER THE INFLUENCE OF SURFACE
SOUTHERLY WINDS, EXPECT FOR TEMPERATURES TO CONTINUE WARMING THROUGH
SUNDAY AS HIGHS WILL REACH THE LOW 80'S FOR SOME THIS WEEKEND. THIS
WILL ALL BE IN ADVANCE OF A STRONG COLD FRONT ASSOCIATED WITH A
PRONOUNCED LOW PRESSURE SYSTEM WHAT WILL WORK ACROSS THE CONUS THIS
WEEKEND, BRINGING SNOW TO THE NORTHERN HALF OF THE COUNTRY, WHILE A
SEVERE WEATHER THREAT EXISTS ALONG AND AHEAD OF THE AFOREMENTIONED
FRONTAL BOUNDARY.
LOOKING TO SUNDAY, MESSAGING HAS NOT CHANGED WHEN COMPARED TO
YESTERDAY. EXPECTATION REMAINS FOR A FAST MOVING LINE OF SHOWERS
AND THUNDERSTORMS SUNDAY AFTERNOON, WITH THE LATEST GUIDANCE
SUGGESTING THAT THE LINE WILL EXIT THE REGION SOMETIME LATE SUNDAY
NIGHT. BY SUNDAY AFTERNOON, A BROAD WARM SECTOR WILL BE PRESENT
AS TEMPERATURES CLIMB INTO THE LOW 80'S. BREEZY SUSTAINED
SOUTHERLY WINDS BETWEEN 15-20 MPH ARE EXPECTED, WITH WIND GUSTS
NEARING 30 MPH AHEAD OF THE FRONT AND THROUGH THE AFTERNOON.
THOUGH THIS WARM SECTOR WILL BE PRESENT, SOUNDING ANALYSIS REVEALS
A WARM LAYER ALOFT THAT WILL ATTEMPT TO CAP ANY ROBUST CONVECTION
AHEAD OF THE MAIN LINE. THAT BEING SAID, AS THE FRONT BEGINS TO
SLICE INTO THE ARK-LA-TEX, DEEP LAYER FLOW ALONG THE FRONT WILL
SUPPORT A DAMAGING WIND THREAT AS THUNDERSTORMS OUTLINE THE COLD
FRONT. AT THE SAME TIME, SUPPORTIVE LAPSE RATES AND WBZ HEIGHTS
BETWEEN 8-9KFT CONTINUE TO SUGGEST THAT HAIL WILL ALSO BE A
CONCERN WITH ANY SEVERE STORMS EARLY ON. FOR NOW, AND UNTIL THE
CAMS CAN GET WITHIN RANGE, THE LOWER-RES GLOBAL AND REGIONAL
REFLECTIVITY OUTPUT SUGGESTS THAT WHAT MAY START BRIEFLY DISCRETE
WILL QUICKLY CONGEAL ALONG THE FRONT AND QUICKLY RACE EASTWARD
ACROSS THE FA. WHILE HAIL AND WIND SEEM TO HAVE TAKEN THE PRIMARY
FOCUS FOR SUNDAY, A TORNADO OR TWO CAN'T BE RULED OUT.
IN THE WAKE OF THE FRONT, THE TIGHT PRESSURE GRADIENT WILL CONTINUE
TO SUPPORT GUSTY WINDS ACROSS THE LOCAL AREA, WITH A SHIFT IN
DIRECTION TO NORTHWESTERLY. AGAIN, SUSTAINED 15-20 MPH WINDS ARE
EXPECTED WITH GUSTS BETWEEN 20-25 MPH MONDAY AFTERNOON. AT THE
SAME, THE AIRMASS QUICKLY TRAILING THE FRONT WILL BEGIN TO
INFLUENCE THE REGION WITH TEMPERATURES MONDAY MORNING SITTING IN
THE UPPER 20'S AND LOW TO MID 30'S. FACTOR IN THE WIND BEHIND THE
FRONT AND FEELS LIKE TEMPERATURES COULD BE IN THE UPPER TEENS TO
LOW AND MIDDLE 20'S THROUGH DAYBREAK. BY THE AFTERNOON, HIGHS WILL
ATTEMPT TO CLIMB INTO THE LOWER 50'S, WITH A ROUGHLY 10 DEG F
INCREASE IN THE MAXT EACH DAY THROUGH THE END OF NEXT WEEK. AT THE
SAME TIME, DRY WEATHER WILL PREVAIL THROUGH THE EXTENDED PERIOD
AS THE INFLUENCE OF RIDGING TO THE WEST KEEPS THE REGION QUIET
AND DRY. THIS WILL BE WORTH MONITORING AS THE AIRMASS IN THE WAKE
OF THE BOUNDARY WILL BE DRY ENOUGH TO SUPPORT RH PERCENTAGES IN
THE LOW 20'S FOR MONDAY AND TUESDAY. THOUGH THE EXTENT OF THE FIRE
WEATHER CONCERN IS A TOUCH LOWER GIVEN RECENT RAINFALL, ANY
BURNING SHOULD BE CLOSELY MONITORED CITING THE GUSTY WINDS AND LOW
RH IN THE FORECAST.
