UPDATE ISSUED AT 814 PM CST SAT NOV 8 2025
ALL PRECIPITATION HAS EXITED THE REGION THIS EVENING. NOW JUST
WATCHING SATELLITE TRENDS AS THE STRATUS DECK PROGRESSES FROM
NORTHWEST TO SOUTHEAST, WITH AREAS OF CLEARING UPSTREAM. THESE
CLEARING AREAS WILL HAVE AN IMPACT ON OVERNIGHT TEMPERATURES.
HOWEVER, OVERALL TEMPERATURE TRENDS ARE MOSTLY ON TRACK. KABR IS A
BIT SLOWER TO DROP, BUT HAS BEEN UNDER PERSISTENT CLOUD COVER
WHERE OTHER LOCATIONS HAVE HAD OCCASIONAL BREAKS. NORTHWEST WINDS
REMAIN GUSTY AND WILL CONTINUE THROUGH THE NIGHT, BUT SHOULD LET
UP SOME AS THE PRESSURE GRADIENT STARTS TO SHIFT EAST/SLACKEN.
WIND CHILL IS STILL EXPECTED BE THE COLDEST OF THE SEASON SO FAR
BY EARLY SUNDAY MORNING (SINGLE DIGITS TO NEAR ZERO). NO MAJOR
CHANGES TO THE GOING FORECAST.

SHORT TERM /THIS EVENING THROUGH SUNDAY NIGHT/
ISSUED AT 223 PM CST SAT NOV 8 2025
A STORM SYSTEM THAT BROUGHT LIGHT, ACCUMULATING SNOWFALL TO PARTS OF
THE CWA IS PUSHING SOUTHEAST OF THE REGION. AS OF 20Z, LIGHT,
SPORADIC SNOW CONTINUES, WITH REGIONAL RADAR RETURNS SHOWING LITTLE
PCPN IN NORTH DAKOTA. THE PCPN SHOULD EXIT THE CWA AROUND 0Z, WITH
DRY CONDITIONS FOR THE REMINDER OF THE SHORT TERM PORTION OF THE
FORECAST. A COLD HIGH PRESSURE CURRENTLY OVER CENTRAL SASKATCHEWAN,
WILL SINK SOUTHWARD TONIGHT THROUGH SUNDAY AND WILL PRODUCE THE
COLDEST AIR SO FAR THIS SEASON. LOW TEMPERATURES FOR TONIGHT IS A
LITTLE DIFFICULT, DUE TO WINDS AND CLOUD COVER. IF THE WINDS
SUBSIDE AND CLOUDS CLEAR, MODEL GUIDANCE SUGGESTS OVERNIGHT LOWS
ABOUT FIVE DEGREES COLDER, OR IN THE SINGLE DIGITS AND LOW TEENS
ABOVE ZERO. IF THE ENVIRONMENT REMAINS WELL MIXED, OR A MOSTLY
CLOUDY NIGHT, LOWS COULD BE +5 DEGREES WARMER, OR IN THE UPPER
TEENS AND MID 20S. NBM GUIDANCE APPEARS REALISTIC AT THIS TIME.
THE SURFACE HIGH PRESSURE SHOULD BE OVER THE REGION ON SUNDAY, WITH
HIGH TEMPERATURES MOSTLY IN THE 20S AND LOW 30S. THESE READINGS ARE
10 TO 15 DEGREES BELOW AVERAGE FOR THIS TIME OF YEAR. WHILE THE NBM
IS SLIGHTLY ON THE HIGHER SIDE GUIDANCE, LOWERING THE FORECAST HIGH
A DEGREE OR TWO DOES NOT CHANGE THE COLD MESSAGE. APPARENT T
VALUES DROP TO WITHIN A FEW DEGREES ON EITHER SIDE OF ZERO SUNDAY
NIGHT INTO MONDAY MORNING.
LOW TEMPERATURES SUNDAY NIGHT SHOULD BE A FEW DEGREES COLDER, WITH
READING IN THE SINGLE DIGITS ON MID TEENS. SUNDAY NIGHT WILL FEATURE
LESS MIXING WINDS AND A MOSTLY CLEAR SKY.
LONG TERM /MONDAY THROUGH SATURDAY/
ISSUED AT 223 PM CST SAT NOV 8 2025
THE LONG TERM STARTS MONDAY MORNING WITH UPPER LEVEL WINDS OUT OF
THE NORTH. WE HAVE A LOW PRESSURE SYSTEM OFF TO OUR SOUTHEAST WITH A
RIDGE COMING IN FROM THE WEST. AN UPPER LEVEL DISTURBANCE MOVES
ACROSS EASTERN SD TUESDAY AND ANOTHER RIDGE MOVES IN FRIDAY INTO
SATURDAY.
NOT REALLY EXPECTING ANYTHING IN THE WAY OF ACTIVE WEATHER THROUGH
THE PERIOD. TEMPERATURES WILL WARM UP INTO THE 50S ON TUESDAY AS
SOME MUCH WARMER AIR MOVES INTO THE REGION. THIS WILL CONTINUE
THROUGH THE END OF THE PERIOD AS ANOTHER ROUND OF WAA STARTS
THURSDAY AND LASTS THROUGH SATURDAY.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
ISSUED AT 1131 PM CST SAT NOV 8 2025
TERMINALS KABR,KATY,KPIR,KMBG
A PERSISTENT LAYER OF MVFR STRATUS CONTINUES TO GRADUALLY SAG
SOUTH OUT OF NORTH DAKOTA. MODELS ARE ALMOST ALL TOO OPTIMISTIC
IN ADVECTING/SCATTERING THIS DECK OF CLOUDS, SO THE FORECAST
TIMING WAS ADJUSTED TO KEEP THE MVFR STRATUS IN PLACE LONGER THAN
ORIGINALLY ANTICIPATED. NORTHWEST WINDS PERSIST THROUGH THE NEXT
24 HOURS. NO REDUCTION TO VSBYS EXPECTED.
