THE 00Z RAOB DATA SHOW THE DEEP TROUGH RESPONSIBLE FOR THIS WEEK'S
HEAVY RAINFALL STRETCHING FROM THE GREAT LAKES INTO THE MID-SOUTH,
CARRYING THE STORM SYSTEM AND ITS MOISTURE AXIS EAST OF THE AREA. WV
IMAGERY SUGGESTS A DRY, SUBSIDENT NORTHWEST FLOW OVER THE ENTIRE CWA
WITH SURFACE HIGH PRESSURE BUILDING IN TODAY, HELPING TO PUSH THE
LAST OF THE REMNANT SHOWERS EAST OF THE AREA BEFORE DAYBREAK OR
SHORTLY AFTER. THE AIRMASS CHANGE WILL FINALLY BRING A FALL-LIKE FEEL
TO THE AREA WITH AFTERNOON DEWPOINTS FALLING INTO THE 40S TODAY. THE
RAIN IS FINISHED, BUT RECOVERY FROM THE FLOODING LINGERS AS AREA
RIVERS WILL TAKE MUCH OF THE WEEKEND TO RECEDE.
THE WEEKEND WILL BE QUIET AND CRISP, VERY FALL-LIKE. HIGHS HOLD
NEAR 70 BOTH DAYS WITH OVERNIGHT LOWS IN THE 40S, LIGHT WINDS, AND
WIDE DIURNAL TEMPERATURE SWINGS UNDER MOSTLY CLEAR SKIES. THE
POTENTIAL FOR FOG CAN'T YET BE RULED OUT BUT LOOKS OVERALL LOW:
TEMPERATURE-DEWPOINT SPREADS GENERALLY NARROW AROUND SUNRISE WITH
LIGHT WINDS OVER GROUND STILL SATURATED FROM THE FLOODING, SO IF
PATCHY FOG DOES FORM IT WOULD LIKELY BE FOCUSED IN RIVER VALLEYS
AND LOW-LYING SPOTS, ESPECIALLY SATURDAY MORNING WITH THE SURFACE
RIDGE CENTERED ACROSS THE AREA. A REINFORCING DRY PUSH SUNDAY
NIGHT KEEPS MONDAY SEASONABLY COOL WITH ANOTHER MORNING IN THE
40S.
IN THE EXTENDED PERIOD, THE UPPER RIDGE AMPLIFIES OVER THE WESTERN
CONUS THIS WEEKEND AND SPREADS EAST ACROSS THE PLAINS NEXT WEEK,
AND EVERY WPC CLUSTER THROUGH THE END OF NEXT WEEK KEEPS POSITIVE
HEIGHT ANOMALIES CENTERED OVER THE CENTRAL CONUS, AND NO CLUSTER
BRINGS A MEANINGFUL WEATHER SYSTEM THROUGH THE AREA. ENSEMBLE
PRECIPITATION STAYS NEAR ZERO THROUGH THE PERIOD AND HIGHS CLIMB
STEADILY, REACHING NEAR 80 BY WEDNESDAY WITH LOWER 80S POSSIBLE
LATE IN THE WEEK, WHICH IS AROUND TO SLIGHTLY ABOVE NORMAL FOR
THIS TIME OF YEAR. BREEZIER SOUTH WINDS RETURN BY LATE WEEK AS THE
RIDGE AXIS SHIFTS EAST AND THE GRADIENT TIGHTENS ACROSS THE REGION
WITH A LEE TROUGH DEEPENING. SLIGHT THUNDERSTORM SIGNALS TOWARD
THE END OF THE PERIOD REFLECT GROWING ENSEMBLE SPREAD RATHER THAN
ANY ORGANIZED SYSTEM IMPACTING THE REGION. CONFIDENCE IN THE DRY,
SLIGHTLY WARMING FORECAST THROUGH THE UPCOMING WEEK IS HIGH.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 1221 AM CDT FRI OCT 2 2026
CONDITIONS CONTINUE TO IMPROVE OVER THE NEXT FEW HOURS AS DRIER AIR
MASS CONTINUES TO PUSH INTO THE REGION. THIS WILL HELP IFR CONDITIONS
OVER THE EASTERN TERMINALS OF KTOP/KFOE IMPROVE QUICKLY THROUGH THE
08-09Z TIME FRAME. LINGERING CLOUDS MOVE OUT OF THE AREA BY SUNRISE
LEAVING A COOL NNE BREEZE IN PLACE THROUGH MUCH OF THE DAY BEFORE
CALMING BY THE END OF THE PERIOD. RIGHT NOW, FOG POTENTIAL INTO THE
NEXT PERIOD APPEARS TO BE LOW BUT WILL NEED TO MONITOR WITH THE
SURFACE RIDGE ACROSS THE AREA AND RESIDUAL MOISTURE NEAR THE SURFACE.
TOP WATCHES/WARNINGS/ADVISORIES
NONE.
