DISCUSSION
ISSUED AT 204 PM CST WED FEB 4 2026
CLOUDS HANG OVER EASTERN NEBRASKA AND WESTERN IOWA THIS
AFTERNOON HELPING TO KEEP TEMPERATURES COOL. TEMPERATURES AS OF
1 PM ARE GENERALLY IN THE UPPER 20S TO MID 30S AND ARE FORECAST
TO REACH INTO THE MID 30S TO NEAR 40 THIS AFTERNOON. OUR LAST
CHANCE FOR ANY TYPE OF PRECIPITATION FOR THE WEEK MOVED THROUGH
THIS MORNING, BRINGING FLURRIES/FREEZING DRIZZLE. THIS IS
CLEARING TO THE SOUTHEAST AND SHOULD BE COMPLETELY WRAPPED UP BY
5PM THIS EVENING.
THE UPPER-LEVEL PATTERN GOING INTO THE WEEKEND WILL SEE A BROAD
RIDGE, CURRENTLY BRINGING RECORD WARM TEMPERATURES TO THE
WESTERN CONUS EXPAND EASTWARD. THIS WILL LEAD TO A TRANSITION
TO ABOVE NORMAL TEMPERATURES ACROSS OUR AREA THROUGH THE
WEEKEND. GOING INTO THURSDAY WE SEE A SHORTWAVE BRING A PUSH OF
NORTHERLY WINDS INTO THE AREA DURING THE MORNING WITH BREEZY
CONDITIONS EXPECTED THROUGH THURSDAY AFTERNOON. THIS AIR IS NOT
GOING TO BE CHILLY AS EXPECTED, THOUGH, SOURCING FROM WESTERN
CANADA WHERE STRONG RIDGING HAS BROUGHT UNSEASONABLY WARM
TEMPERATURES TO ALBERTA AND BRITISH COLUMBIA. THIS COMBINED WITH
THE RIDGE BUILDING IN INCREASING GEOPOTENTIAL HEIGHTS ACROSS
THE REGION ON THURSDAY WILL ALLOW HIGHS TO WARM WELL ABOVE
NORMAL. WE'LL SEE HIGHS IN THE 50S ACROSS EASTERN NEBRASKA AND
WESTERN IOWA, SOME SPOTS MAY EVEN WARM INTO THE LOW 60S IN OUR
WESTERN COUNTIES.
FRIDAY WE SEE ANOTHER SHORTWAVE TRAVEL ALONG THE UPPER-LEVEL
JET TO OUR EAST WHICH WILL BRING BACK A PERIOD OF BREEZY
NORTHERLY WINDS FRIDAY MORNING. THIS AIR MASS SOURCES A LITTLE
FARTHER EAST, PULLING IN SOME OF THE COOLER AIR OVER
SASKATCHEWAN AND MANITOBA. THIS MEANS TEMPERATURES COOL BACK
DOWN A BIT, WITH HIGHS IN THE MID 40S TO LOW 50S FRIDAY
AFTERNOON.
THE NEXT IN THE SERIES OF CLIPPER SHORTWAVES MOVES IN EARLY
SATURDAY BRINGING A SHIFT BACK TO SOUTHERLY WINDS. THIS WIND
SHIFT MAY NOT LAST LONG ENOUGH TO IMPACT TEMPERATURES MUCH, BUT
SOME AREAS IN NORTHEAST NEBRASKA MAY WARM INTO THE LOW-TO-MID
50S WHILE THE REST OF OUR AREA STAYS IN THE 40S SATURDAY
AFTERNOON.
SUNDAY INTO EARLY NEXT WEEK WE SEE THE UPPER-LEVEL RIDGE
CONTINUE TO EXPAND AND BREAK DOWN, BRINGING AN END TO THE
CLIPPER SYSTEMS OUT OF CANADA AND BRINGING IN SIGNIFICANTLY
WARMER TEMPERATURES SUNDAY AND MONDAY. ENSEMBLES SHOW FAIRLY
GOOD CONFIDENCE (60-70% CHANCE) IN HIGHS REACHING INTO THE 60S
FOR HIGHS SUNDAY AFTERNOON ALONG AND WEST OF HIGHWAY 81. MONDAY
THIS POTENTIAL EXPANDS EASTWARD WITH A 60-80+% CHANCE FOR HIGHS
AT OR ABOVE 60. WE MAY NOT BE TALKING RECORD HIGHS JUST YET AS
RECORDS FOR SUNDAY AND MONDAY GENERALLY ARE IN THE UPPER 60S TO
70, BUT IT WILL CERTAINLY BE WELL ABOVE OUR NORMAL HIGHS IN THE
MID 30S.
AS THE RIDGE CONTINUES TO BREAK DOWN ACROSS THE CENTRAL CONUS
NEXT WEEK, WE'LL SEE TEMPERATURES START TO COOL BACK DOWN
TOWARD NORMAL. WITH THIS RIDGE GOING AWAY WE SEE A MAJOR PATTERN
CHANGE AWAY FROM THE WESTERN RIDGE EASTERN TROUGH REGIME THAT
HAS BEEN IN PLACE FOR THE LAST FEW WEEKS. INSTEAD, WE SEE A
BROAD TROUGH MOVE ONTO THE WEST COAST FROM THE GULF OF ALASKA
SHIFTING FLOW TO SOUTHWESTERLY ACROSS THE CENTRAL CONUS. THIS
SHOULD MEAN A MORE ACTIVE PATTERN WITH CHANCES FOR RAIN
RETURNING AS EARLY AS TUESDAY, BUT MORE LIKELY DURING THE
WEDNESDAY-THURSDAY TIME FRAME. WITH MILDER TEMPERATURES IN
PLACE, I'D EXPECT PRECIPITATION CHANCES TO STAY AS RAIN AT LEAST
INITIALLY UNTIL ANY OF THE TRAILING SYSTEMS IS ACTUALLY ABLE TO
PULL COLDER AIR SOUTH OUT OF CANADA. THIS DOES NOT APPEAR LIKELY
THROUGH AT LEAST NEXT WEDNESDAY.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
ISSUED AT 520 PM CST WED FEB 4 2026
MVFR CEILINGS AND NORTHWEST WINDS CONTINUE ACROSS THE REGION.
SURFACE HIGH PRESSURE IS BUILDING EAST TOWARDS THE AREA, ERODING
CLOUDS. VFR CEILINGS AND LIGHT WINDS SHIFTING TO THE SOUTH AND
SOUTHWEST OVERSPREAD AREA TERMINALS OVER THE NEXT SEVERAL
HOURS. A COLD FRONT WILL BE FAST APPROACHING THE REGION
OVERNIGHT. AS THE FRONT APPROACHES A WESTERLY WIND SHIFT AND
LLWS IS EXPECTED TO DEVELOP BETWEEN 09-11Z. A COUPLE HOURS AFTER
THIS, WINDS WILL BECOME NORTHWESTERLY WITH A FEW GUSTS BEHIND
THE FRONT. LLWS IS ANTICIPATED TO CONTINUE INTO THE MORNING
HOURS BEHIND THE FRONT. DAYTIME HEATING BY MID-MORNING AT AROUND
15Z IS EXPECTED TO END ANY LLWS.
