UPDATE ISSUED AT 1022 AM CDT MON OCT 5 2026
BAND OF MID-LEVEL WARM AIR ADVECTION CLOUDS THAT MODELS HAD
CAPTURED NICELY YESTERDAY CONTINUES TO PUSH OFF TO THE EAST AND
NEARLY OUT OF THE CWA, LEAVING BEHIND MOSTLY SUNNY SKIES FOR
TODAY. NO BIG CHANGES PLANNED FOR THE "TODAY" PERIOD AS WE'LL
SEE HIGHS IN THE 70S TO LOW/MID 80S, WITH BREEZY AND GUSTY
SOUTHERLY WINDS.
DISCUSSION
ISSUED AT 1225 AM CDT MON OCT 5 2026
WARM ADVECTION MID CLOUDS DEVELOPING ON SATELLITE, AND FORECAST IN
SOUNDINGS/NBM SKY COVER. ONLY ABOUT 50MB THICKNESS AT AROUND 700MB,
SO WILL HAVE A LIMITED IMPACT ON THE FORECAST ASIDE FROM LESS THAN
FULL SUNSHINE FOR SOME LOCATIONS IN THE EAST TODAY. LOCAL DOWNSLOPE
CONDITIONS FOR A BRIEF PERIOD TONIGHT WITH BUFKIT PROFILES
INDICATING ABOUT 40KTS IN THE CRITICAL LAYER, AND IT WILL TAKE JUST
BEFORE THE FRONT COMING THROUGH, WHEN WE BRIEFLY ACHIEVE A SOUTHWEST
ORIENTED WIND, TO REALLY TAKE EFFECT. OTHERWISE JUST BREEZY WITH
SOUTH FLOW AND 1/2KM WINDS AT ABOUT 25-30KTS.
TUESDAY WILL BE DOMINATED BY WEAK LOW LEVEL FLOW AND WEAK COLD
ADVECTION, WITH ENHANCED MIXING ON A NORTHWEST WIND COMPONENT. NBM
HIGHS AROUND 80.
THE REST OF THE WEEK REMAINS MILD ALBEIT NOT QUITE AS ABOVE NORMAL
AS THE PATTERN IS DOMINATED BY A NORTHWESTERLY FLOW REGIME.
FOR THE WEEKEND, CURRENTLY DETERMINISTIC EC/GFS/CANADIAN ALL DEPICT
SOME FORM OF RIDGE CROSSES THE NORTH CENTRAL CONUS FOLLOWED BY A
DEEPENING TROUGH OVER THE WESTERN CONUS. SOUTHWEST FLOW REGIME WILL
HELP GENERATE A LOW OVER THE NORTHERN ROCKIES FOLLOWED BY A FRONTAL
PASSAGE. STARTING TO SEE SOME NBM POPS CREEP INTO SAT/SUN BUT ITS
STILL PRETTY FAR OFF TO COME TO ANY FINAL CONCLUSIONS REGARDING THE
WEEKEND FORECAST.
