TODAY AND TOMORROW:
WATER VAPOR IMAGERY THIS AFTERNOON FEATURES BROAD NORTHWESTERLY FLOW
ACROSS THE CONUS, WITH SLIGHT RIDGING PROPPING THAT FLOW PATTERN UP
FROM THE PACIFIC COAST. TAKING A LOOK AT THE SURFACE, WE FIND
OURSELVES IN THE THE PATH OF A NORTHWARD-ADVANCING WARM FRONT THAT
HAS HELPED POWER TEMPERATURES INTO THE UPPER 70S TO LOW 80S ALREADY.
HIGH TEMPERATURE GUIDANCE CONTINUES ALONG THE UNDER-PREDICTIVE
TREND AS OF LATE, WHICH HAS LONGER-TERM BIAS CORRECTION HURTING
THE FORECAST. LATER THIS EVENING, THE LOW-LEVEL JET IS EXPECTED
TO RAMP UP AS THE WARM FRONT LIFTS NORTHWARD, RESULTING IN A
NARROW BAND OF RAIN CHANCES (15-25%) THAT WILL SKIRT ACROSS THE
NORTHEASTERN FORECAST AREA. TOTAL AMOUNTS SHOULD ONLY BE A TRACE
TO A COUPLE OF HUNDREDTHS, WITH MOST STAYING DRY. ALONG AND
JUST NORTH OF THAT FRONT, WE COULD SEE SOME AREAS OF FOG DEVELOP
ACROSS NORTHEAST INTO NORTH-CENTRAL NEBRASKA, WITH VISIBILITIES
DROPPING BELOW 1 MILE TOMORROW MORNING AFTER 4 AM (20% CHANCE).
ANOTHER WARM DAY IS FORECAST FOR TOMORROW AS SOUTHERLY WINDS
RETURN, WITH NO ADDITIONAL RAIN CHANCES AND HIGHS IN THE MID-
TO-UPPER 80S. GUSTS OF 20-25 MPH WILL BE CREEPING IN FROM THE
WEST, AND WILL BE STRONGEST ACROSS NORTHEAST AND NORTH-CENTRAL
NEBRASKA.
SATURDAY AND BEYOND:
OUR HOTTEST DAY OF THE FORECAST IS ON TAP FOR SATURDAY AS A RIDGE TO
THE WEST PROGRESSES QUICKLY TO THE EAST THROUGH THE AREA AND WE
QUICKLY TRANSITION TO STIFF SOUTHWESTERLY FLOW. WIND GUSTS OF
35-45 MPH ARE EXPECTED DURING THE AFTERNOON HOURS, AND SINCE WE
WON'T HAVE GREAT ACCESS TO RICH GULF MOISTURE, WE'LL BE KEEPING
AN EYE ON THE EVOLVING FIRE DANGER AS WE GET CLOSER. AS OF NOW,
TALL STANDING CROPS REMAIN IN PLACE AND CONTINUE TO CURE AHEAD
OF HARVEST, WITH SATURATED SOILS CONTINUING TO DRY WITH THE
WARMER WEATHER THROUGH THE WEEK. THIS WILL BE THE MAIN FUEL
SOURCES THAT INCREASE THE OVERALL FIRE DANGER, WITH OTHER FUELS
TIED TO GRASSLAND AND TREE COVER STILL BEING ON THE GREEN SIDE
AND STILL HAVE A WAYS TO GO. NEVERTHELESS, DRY AND WINDY
CONDITIONS REMAIN THE FOCUS FOR THE WEEKEND FORECAST THAT
CONTINUES INTO SUNDAY BUT WITH LOWER WIND SPEEDS.
A CHANGE COMES IN THE FORM OF A COLD FRONT PUSH THOSE
CONDITIONS SOUTHWARD MONDAY WITH GUSTS SHIFTING SOUTHEASTWARD
ACROSS THE AREA. BEHIND THE FRONT, RAIN CHANCES DO CREEP IN BUT
WILL REMAIN ON THE LOWER SIDE UNTIL BETTER MOISTURE ARRIVES TO
THE AREA. WE WILL GET GOOD SHOTS OF MOISTURE TUESDAY AND
WEDNESDAY NEXT WEEK AS A DEEP CUTOFF LOW DEVELOPS OVER THE
WESTERN CONUS. THIS LOW IS CURRENTLY FORECAST TO WEAKEN AS IT
TRANSLATES ACROSS THE ROCKIES BEFORE STRENGTHENING AS IT EJECTS
ACROSS THE CENTRAL CONUS. WIDESPREAD RAIN CHANCES WILL RETURN TO
THE AREA AIDED BY A STRONG MASS RESPONSE AHEAD OF THE LOW, BUT
RAIN THIS TIME AROUND ISN'T EXPECTED TO BE THE SAME AS THE
RECENT TROPICALLY-AIDED RAINFALL THAT CAUSE FLOODING LAST WEEK.
WE'LL HAVE LOWER PWATS, LESS RESIDENCE TIME OF HIGH-END
RAINFALL, AND A LESS DIRECT HIT FROM ADDITIONAL FORCING THAT LET
THE LAST EVENT REACH ITS HEIGHTS. REGARDLESS, DON'T PUT AWAY
THE UMBRELLA BECAUSE NEXT WEEK TAKES A TURN FOR COOLER TEMPS
(70S) AND DAILY RAIN CHANCES AS THAT SYSTEM ARRIVES.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1211 PM CDT THU OCT 8 2026
SOUTHERLY WINDS ARE IN PLACE THIS AFTERNOON, WHICH SHOULD
QUICKLY BECOME SOUTHEASTERLY OVER THE NEXT HOUR THROUGH THE REST
OF THE DAY AS MOSTLY CLEAR SKIES ARE INTERRUPTED BY A FEW HIGH
CLOUDS. HEADING INTO THE OVERNIGHT HOURS, WE'RE WATCHING
POTENTIAL FOR KOFK TO SEE SOME LOWER CEILINGS AND AREAS OF
PATCHY FOG, WITH CONFIDENCE NOT BEING HIGH ENOUGH TO INCLUDE IN
THE TAF AS OF NOW. STARTING 06-07Z, STRONG WINDS WILL DEVELOP
NEAR KOMA/KLNK, WITH SPEEDS OF 42-47 KTS AT FL015 CAUSING LOW-
LEVEL WIND SHEAR CONCERNS. WINDS AT THE SURFACE WILL WAVER
SLIGHTLY TO THE SOUTHWEST AROUND SUNRISE BEFORE THEY RETURN
SOUTHERLY BY THE AFTERNOON HOURS.
