DISCUSSION
ISSUED AT 1122 PM CDT SAT OCT 24 2026
A COLD FRONT MOVED ACROSS EASTERN NEBRASKA THIS EVENING,
CURRENTLY HUNG UP ACROSS FAR SOUTHEAST NEBRASKA. TEMPERATURES
DROPPED BEHIND THE FRONT WITH MOST OF EASTERN NEBRASKA AND
WESTERN IOWA NOW IN THE MID-40S TO MID-50S. LOOKING AT THE
BROADER UPPER-LEVEL PATTERN, WE HAVE A RIDGE OVER THE CENTRAL
CONUS THIS EVENING. A TROUGH STRETCHES FROM THE MONTANA ROCKIES
SOUTH INTO NEVADA AND FAR SOUTHERN CALIFORNIA. A STRONG NEARLY
MERIDIONAL JET STREAK IS IN PLACE STRETCHING FROM NEW MEXICO
NORTH THROUGH THE DAKOTAS.
OVERNIGHT INTO SUNDAY WE'LL SEE A DEVELOPING LOW OVER EASTERN
COLORADO RAMP UP SOUTHERLY FLOW OVER THE SOUTHERN AND CENTRAL
PLAINS. THIS WILL PUSH THE COLD FRONT BACK NORTH AS A WARM
FRONT, BRINGING WARMER TEMPERATURES BACK INTO EASTERN NEBRASKA
AND SOUTHWEST IOWA FOR SUNDAY AFTERNOON. WHILE HIGHS STAY IN THE
LOW 50S FOR OUR FAR NORTHERN COUNTIES, HIGHS ACROSS SOUTHEAST
NEBRASKA WILL BE IN THE UPPER 70S TO NEAR 80. RAIN CHANCES ALSO
GET PUSHED BACK NORTH MOSTLY INTO SOUTH DAKOTA FOR MUCH OF THE
DAY ON SUNDAY.
THE DEVELOPING SURFACE LOW TRAVELS ALONG THE FRONTAL BOUNDARY
NORTHEAST ACROSS CENTRAL NEBRASKA SUNDAY NIGHT INTO MONDAY,
INCREASING RAIN CHANCES AGAIN FOR NORTHEAST NEBRASKA. MEANWHILE
THE REST OF EASTERN NEBRASKA AND SOUTHWEST IOWA MAINLY SEES HIGH
CLOUDS WITH OCCASIONAL BREAKS OF SUNSHINE THROUGH MONDAY. THE
OPEN WAVE BRINGING THIS LOW PRESSURE SYSTEM THROUGH SHIFTS OFF
TO THE NORTHEAST AS ANOTHER ALEUTIAN LOW PUSHES IN TO THE PACNW.
AS THIS TROUGH MOVES ACROSS THE NORTHERN PLAINS, WE'LL SEE
ANOTHER ROUND OF POTENTIAL SHOWERS AND STORMS ON TUESDAY
EVENING ACROSS MORE OF OUR AREA. EVEN WITH THESE SYSTEMS MOVING
THROUGH OUR FRONTAL BOUNDARY FROM THE WEEKEND STAYS FAIRLY
STATIONARY, OCCASIONALLY DROPPING SOUTH THEN SHIFTING BACK
NORTH. THIS WILL KEEP OUR TEMPERATURES FAIRLY STEADY THROUGH THE
WEEK WITH COOLER HIGHS IN THE 50S AND 60S OVER NE NEBRASKA AND
HIGHS STAYING IN THE 70S TO NEAR 80 ACROSS SOUTHEAST NEBRASKA
AND SOUTHWEST IOWA.
ANOTHER SYSTEM DROPPING SOUTH OUT OF THE GULF OF ALASKA, RIDING
DOWN THE WEST COAST TOWARD THE END OF THE WEEK WILL SET UP MORE
SOUTHWESTERLY FLOW ACROSS THE WESTERN CONUS. THIS BUILDS UP
RIDGING OVER THE CENTRAL US TRENDING TEMPERATURES SLIGHTLY
WARMER TOWARD THE END OF THE WORKWEEK. WEAK SHORTWAVES WILL
KEEP PERIODIC SHOWERS AND STORMS IN THE FORECAST WITH NO
ORGANIZED THREAT FOR ANYTHING SEVERE IN SIGHT.
