SCATTERED HIGH CLOUDS ACROSS THE AREA THIS EVENING. THE UPPER-
LEVEL PATTERN SHOWS BROAD RIDGING OVER THE WESTERN THIRD OF THE
CONUS WITH BROAD TROUGHING OVER THE EASTERN TWO-THIRDS.
OVERNIGHT TONIGHT, HIGH CLOUDS SHOULD MAKE IT MORE DIFFICULT
FOR FOG TO FORM, BUT WE COULD STILL SEE PATCHY FOG IN LOW-LYING
AREAS AND RIVER VALLEYS DEVELOP, BURNING OFF AFTER SUNRISE.
THURSDAY WE'RE LOOKING AT ANOTHER QUIET DAY WITH TEMPERATURES IN
THE UPPER 70S TO LOW 80S FOR THE AFTERNOON.
A WEAK DEVELOPING LOW OVER THE NEBRASKA PANHANDLE WILL BRING A
WARM FRONT THROUGH EASTERN NEBRASKA THURSDAY NIGHT INTO EARLY
FRIDAY. 00Z CAMS SHOW A LINE OF SHOWERS/STORMS DEVELOPING ALONG
THAT WARM FRONT NEAR THE MISSOURI RIVER VALLEY OF NORTHEAST
NEBRASKA INTO WESTERN IOWA. SOUNDINGS SHOW SUFFICIENT ELEVATED
INSTABILITY, BUT LOW-LEVEL DRY AIR WILL MAKE IT DIFFICULT FOR
ANY PRECIP TO REACH THE GROUND. GOOD ENOUGH FOR A 20-30 PERCENT
CHANCE OF SHOWERS/STORMS THOUGH.
INCREASED WARM-AIR ADVECTION ON FRIDAY WILL BRING TEMPERATURES
BACK UP INTO THE MID 80S. WITH RECENT TRENDS FOR THE NBM BEING A
BIT LOW, WE COULD POTENTIALLY APPROACH RECORDS WHICH ARE 88 FOR
FRIDAY AND 91 FOR SATURDAY AT OMAHA (90 FRIDAY AND 91 SATURDAY
FOR LINCOLN).
SATURDAY WE SEE A DEEPENING LOW PRESSURE SYSTEM CROSSING SOUTH-
CENTRAL CANADA PUSH INTO THE STRONG RIDGE OVER THE GREAT LAKES
REGION, STEEPENING THE PRESSURE GRADIENT ACROSS THE NORTHERN
PLAINS DOWN TO OUR AREA. THIS WILL REALLY RAMP UP WINDS ACROSS
OUR AREA WITH WINDS GUSTING 35-45 MPH EXPECTED, STRONGEST OVER
NORTHEAST NEBRASKA. THESE WINDS WILL BE SOURCING AIR FROM THE
DRIER AREAS OF NEW MEXICO, WEST TEXAS AND WESTERN KANSAS. DRY,
WINDY CONDITIONS OVER THE DRIER PARTS OF CENTRAL AND
NORTHEASTERN NEBRASKA MAY CREATE FIRE WEATHER CONCERNS SATURDAY
AFTERNOON. THIS PATTERN BREAKS DOWN SATURDAY NIGHT INTO SUNDAY
AS THE LOW IN CANADA BREAKS DOWN AS IT GETS FORCED OVERTOP THE
RIDGE.
LOOKING WEST TOWARD THE LATTER HALF OF THE WEEKEND WE SEE A DEEP
TROUGH SLIDE DOWN THE WEST COAST SETTING UP A FAIRLY ACTIVE
SOUTHWESTERLY FLOW PATTERN GOING INTO NEXT WEEK. RIDGING PUSHING
UP OUT OF MEXICO INTO TEXAS WILL SERVE TO INTENSIFY THE UPPER-
LEVEL JET SPANNING FROM SOUTHERN CALIFORNIA NORTHEAST INTO
NEBRASKA AND SOUTH DAKOTA. THIS BAROCLINIC PATTERN DECREASES
CONFIDENCE IN THE FINE DETAILS OF THE FORECAST FOR NEXT WEEK,
BUT ENSEMBLE GUIDANCE GENERALLY SHOW A COLD FRONT BRINGING
TEMPERATURES BACK DOWN MONDAY WITH PRECIP CHANCES RETURNING
TUESDAY OR WEDNESDAY. THIS PATTERN IS PRIME FOR A PROTOTYPICAL
FALL-LIKE SEVERE WEATHER EVENT SOMEWHERE ACROSS THE GREAT PLAINS
LATER NEXT WEEK AS THE DEEP LOW OVER SOUTHERN CALIFORNIA GETS
REABSORBED BACK INTO THE UPPER-LEVEL FLOW MOVING IN THURSDAY OR
FRIDAY. MUCH COOLER AIR MOVES IN BEHIND IT. CERTAINLY A TIME
PERIOD TO WATCH.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
ISSUED AT 536 PM CDT WED OCT 7 2026
VFR CONDITIONS EXPECTED TO PERSIST THROUGH THE TAF PERIOD WITH
PASSING HIGH CLOUDS. WINDS WILL BE LIGHT OVERNIGHT, SHIFTING TO
SOUTHEASTERLY WEDNESDAY MORNING. A FEW MODELS SUGGEST POTENTIAL
FOR FOG DEVELOPMENT IN LOW-LYING AREAS AND RIVER VALLEYS AROUND
10-13Z, BUT CHANCES FOR IMPACTS TO THE TERMINALS REMAIN BELOW
20 PERCENT. WINDS WILL BE INCREASING OUT OF THE SOUTH-SOUTHEAST
TO 6-10 KT BY THE AFTERNOON.
