DISCUSSION
ISSUED AT 147 PM CDT FRI MAR 27 2026
A SHARP POLAR COLD FRONT IS CURRENTLY SWEEPING THROUGH THE REGION,
AND THEN QUICKLY MOVE THROUGH THE ENTIRE AREA BY LATE THIS
EVENING. THE STRONG WIND AND DRY AIR FOLLOWING THIS MOSTLY RAIN-
FREE FRONT WILL BE IMPACTFUL AS DESCRIBED BELOW.
CONCERNING STRONG WINDS: THE DENSITY DIFFERENCE OF THE PRE AND
POST FRONTAL AIRMASSES WITH THE COLD FRONT WILL SUPPORT A BIG WIND
SURGE THROUGH THE ARKLAMISS DELTA REGION AS WE GO THROUGH THE
AFTERNOON AND EVENING. MEDIUM TO HIGH PROBABILITIES FOR WIND
GUSTS > 40 MPH IN THAT AREA HAVE PROMPTED FORMAL MESSAGING FOR
THE WIND THREAT, AND A WIND ADVISORY'S ISSUANCE LOOKS INCREASINGLY
LIKELY THIS EVENING. THE TIGHT PRESSURE GRADIENT WILL MAINTAIN
STRONG WIND POTENTIAL THROUGH THE NIGHT AND PERHAPS INTO SATURDAY
MORNING, BUT THE GRADIENT SHOULD RELAX AS WE GO THROUGH THE DAY,
HELPING TO BRING A DIMINISHING WIND THREAT.
CONCERNING FIRE WEATHER DANGER: ANY RAINFALL ASSOCIATED WITH THE
FRONT WILL BE VERY LIGHT AND INSIGNIFICANT. NEAR TERM GUIDANCE IS
ALL ON BOARD WITH THE INCREASED FIRE DANGER THREAT SATURDAY DUE
TO MUCH DRIER AIR (MINIMUM RH < 25%) AND BREEZY CONDITIONS (PEAK
GUSTS UP TO 30 MPH) CONTINUING INTO SATURDAY. COMBINED WITH DRY
FUELS AND NATIVE VEGETATION IN A CRITICAL POINT IN GROWTH SEASON,
A RED FLAG WARNING HAS BEEN ISSUED FOR SATURDAY FROM 11AM TO 6PM
WHEN RHS REACH A CRITICAL POINT.
OTHERWISE, SLIGHTLY COOLER TEMPERATURES THIS WEEKEND WILL BE
BRIEF AS WARM ADVECTION INCREASES AGAIN AND CONTINUES THROUGH
EARLY TO MID NEXT WEEK. THIS SHOULD HELP TO BOOST RAIN CHANCES,
BUT ONLY FOR DISORGANIZED, AND DIURNALLY ENHANCED SHOWER ACTIVITY
AS THE SUBTROPICAL HIGH SHIFTS TO OUR SOUTHEAST AND BECOMES
CENTERED NEAR THE FL PENINSULA. EXPECT THE NEXT POLAR FRONT TO
MOVE TOWARD THE AREA LATE NEXT WEEK WITH PERHAPS GREATER MOISTURE
TO WORK WITH. /EC/KP/
