702 PM CDT TUE APR 7 2026
..NEW MESOSCALE UPDATE, AVIATION
KEY MESSAGES
- THE DRY WEATHER WILL CONTINUE THROUGH THE END OF THE WEEK,
WITH HIGHS IN THE LOW TO MID 80S OVER THE WEEKEND.
MESOSCALE UPDATE
ISSUED AT 649 PM CDT TUE APR 7 2026
CLEAR WEATHER WILL CONTINUE THROUGH THE DAY TOMORROW AS HIGH
PRESSURE OVER THE EASTERN 2/3RDS OF THE COUNTRY IS OUR DOMINANT
FEATURE. THE FORECAST ELEMENTS HAVE BEEN UPDATED THROUGH TOMORROW
AFTERNOON, BUT NO SIGNIFICANT CHANGES WERE MADE. COLD ADVECTION
HAS ENDED IN THE REGION, BUT THE ANTICYCLONIC FLOW AROUND THIS
SURFACE HIGH IS REINFORCING DRY AIR ACROSS THE REGION. SUCCESSIVE
DRY AND BREEZY DAYS WILL CONTRIBUTE TO A GRADUAL LOWERING OF FUEL
MOISTURES AGAIN, BUT DO NOT ANTICIPATE HAZARDOUS FIRE WEATHER
CONCERNS THROUGH TOMORROW. AFTERNOON RH TOMORROW SHOULD DROP TO
AROUND 30-35 PERCENT AT MOST LOCATIONS. /NF/
DISCUSSION
ISSUED AT 138 PM CDT TUE APR 7 2026
THROUGH TONIGHT:
THE DRY WEATHER WILL CONTINUE THIS AFTERNOON AND BEYOND, WITH HIGH
TEMPERATURES IN THE MID TO UPPER 70S F. CLOUD COVER WILL BEGIN TO
INCREASE OVERNIGHT WHICH WILL RESULT IN OVERNIGHT LOWS ABOUT 10
DEGREES F WARMER THAN THE LAST COUPLE OF NIGHTS WITH REDUCED
RADIATIONAL COOLING AND STARTING FROM A WARMER HIGH TODAY AS WELL,
DIPPING INTO THE MID 50S F.
TOMORROW INTO EARLY NEXT WEEK:
REMNANT TROUGHING WILL YIELD TO INCREASING HEIGHTS ALOFT THROUGH THE
WEEKEND WITH AFTERNOON HIGHS A BIT WARMER EACH DAY; BY FRIDAY AND
SATURDAY AFTERNOON HIGHS WILL LIKELY FEATURE WIDESPREAD LOWER 80S F
WITH MID 80S F BY SUNDAY AND MONDAY. SOUTHEASTERLY FLOW BEGINS TO
BECOME INCREASINGLY ESTABLISHED BEGINNING TOMORROW, BUT IT WILL TAKE
UNTIL THURSDAY BEFORE WE SEE LARGE INCREASES IN SURFACE HUMIDITY.
WITH SURFACE TRAJECTORIES ESE TO SE, ONLY A RETURN OF MODIFIED
CONTINENTAL AIR IS LIKELY THROUGH THE WEEKEND AND DEW POINTS LIKELY
WON'T CRACK 60 F AGAIN FOR MOST UNTIL WE HEAD INTO NEXT WEEK. THIS
IN ADDITION TO THE INCREASED UPPER HEIGHTS WILL ALLOW DRY WEATHER TO
CONTINUE FOR MUCH OF THE AREA THROUGH THE FORECAST PERIOD AS THE
PRIMARY STORM TRACK REMAINS WELL TO OUR WEST ON THE WESTERN FLANK OF
THE UPPER RIDGE. ORGANIZED STORMS SUNDAY THAT DEVELOP OVER THE
SOUTHERN PLAINS COULD HAVE ENOUGH LONGEVITY TO BRING SOME SHOWERS TO
PORTIONS OF NORTHEAST LOUISIANA AND SOUTHEAST ARKANSAS ON SUNDAY
NIGHT BUT WILL BE ON A DECIDEDLY WEAKENING TREND BY THE TIME THEY
ARRIVE. GUIDANCE IN THE DAY 7-8 RANGE SUGGESTS SOME RISK FOR A COLD
FRONT TO PRESS INTO THE AREA BRINGING SOME CHANCE FOR SHOWERS OR
STORMS BUT CONFIDENCE IS LOW.
DESPITE WIDESPREAD RECENT RAINS IN THE 1-2.5" RANGE, THE LIKELY
UPCOMING DRIER PERIOD COULD MEAN FIRE WEATHER CONCERNS COULD BEGIN
TO INCREASE AGAIN LATER THIS WEEK AND BEYOND. THAT POSSIBILITY WILL
BE MONITORED OVER THE COMING DAYS. /86/
