DISCUSSION
ISSUED AT 230 PM CST FRI JAN 2 2026
..SYNOPSIS
NORTHWESTERLY FLOW ALOFT WITH SEVERAL WEAK EMBEDDED SHORTWAVES
WILL CONTINUE INTO TONIGHT, BEFORE RIDGING BRIEFLY BUILDS OVER
THE ROCKIES AND WESTERN PLAINS FOR SATURDAY. THE RIDGE WILL BE
SHORT LIVED AS ANOTHER SHORTWAVE STARTS TO COME OVER THE TOP OF
IT SATURDAY NIGHT AND ACROSS OUR REGION INTO MN BY SUNDAY. NEAR
ZONAL FLOW FOR THE EARLY PART OF THE WORK WEEK, THEN FLOW STARTS
TO BECOME MORE SOUTHWESTERLY WEDNESDAY INTO THURSDAY. ENSEMBLES
START TO BRING THE TROUGH INTO THE WESTERN PLAINS ON FRIDAY, BUT
DIFFER SIGNIFICANTLY ON HOW THEY HANDLE SPECIFICS. SOME OF THE
DETERMINISTIC RUNS TAKE A LOW FROM CO INTO THE UPPER MIDWEST
FRIDAY INTO SATURDAY, BUT OTHER RUNS DO NOT AND SPREAD IS ALL
OVER THE PLACE. WILL CONTINUE TO MONITOR THE SYSTEM, BUT AT THIS
POINT WILL HOLD OFF ON ANY MESSAGING.
..LIGHT SNOW TONIGHT
A FEW OF THE WEAK SHORTWAVES WILL DIG THROUGH THE NORTHWESTERLY
FLOW TONIGHT. ONE SUCH VORT NEAR THE SASKATCHEWAN/MANITOBA
BORDER IS ALREADY STARTING TO BRING SOME LIGHT RADAR RETURNS TO
NORTH CENTRAL ND, AND THAT SHOULD SPREAD SOUTHEASTWARD THIS
EVENING. ANOTHER SHORTWAVE IS EXPECTED TO MOVE TOWARDS THE LAKE
OF THE WOODS AREA LATER TONIGHT. NEITHER SHORTWAVE IS EXPECTED
TO BE VERY STRONG OR HAVE A LOT OF MOISTURE TO WORK WITH, BUT
COULD SEE A DUSTING UP TO AN INCH OR SO OF FLUFF. WARM AIR
ADVECTION KICKS IN TOWARDS TOMORROW MORNING IN EASTERN ND, AND
THERE ARE SOME MODEL SOUNDINGS INDICATING THE POTENTIAL FOR
FREEZING DRIZZLE ALONG OUR WESTERN BORDER. HOWEVER,
BEST SATURATION IN THE LOW LAYERS AT THIS POINT LOOKS LIKE IT
WILL STAY TO OUR WEST, WITH BETTER CHANCES FOR ICING LATER IN
THE WEEKEND.
..SNOW AND MIXED PRECIPITATION SUNDAY AND SUNDAY NIGHT
STRONGER SYNOPTIC FORCING AND EVEN A LITTLE BIT OF FRONTOGENESIS
WITH THE SHORTWAVE COMING OVER TOP OF THE RIDGE ON SUNDAY.
SOUTHEASTERLY WINDS WILL BRING WARMER AIR AND MORE MOISTURE INTO
THE BOUNDARY LAYER. MODEL SOUNDINGS SHOW BOTH A WARM LAYER ALOFT
SUNDAY, AND THERE WILL ALSO BE A LOSS OF ICE IN THE DENDRITIC
GROWTH ZONE THAT COULD BRING A MIX OF FREEZING RAIN OR DRIZZLE
ON THE BACKSIDE OF THE SYSTEM. PROBABILITIES GIVEN BY NBM FOR
PRECIP TYPE ARE HIGHEST FOR SLEET, BUT THERE IS ENOUGH OF A
CHANCE FOR FREEZING RAIN OR DRIZZLE TO GIVE A 20 PERCENT CHANCE
FOR LIGHT ICE ACCUMULATION. GIVEN THAT ANY SMALL ICE
ACCUMULATION CAN CAUSE ISSUES, WILL CONTINUE TO MONITOR THIS
PERIOD CLOSELY AND SEE IF ICING PROBABILITIES INCREASE.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
ISSUED AT 1119 PM CST FRI JAN 2 2026
AVIATION IMPACTS WILL BE PRIMARILY TIED TO SNOW FOR ALL TAF
SITES AND THE POTENTIAL FOR BRIEF REDUCTIONS IN CEILINGS TO
MVFR CEILINGS IN EASTERN NORTH DAKOTA.
SNOW WILL MOVE EASTWARD THROUGH THE OVERNIGHT HOURS BRIEFLY
REDUCING VISIBILITY TO AT WORST 2SM, ALTHOUGH MOST SHOULD REMAIN
BETWEEN 6 AND 10 MILES. BRIEF REDUCTIONS IN CEILINGS AS WELL MAY
FALL TO 025-030 PUSHING THINGS TO MVFR. SNOW WILL MOVE AWAY BUT
CONTINUE TO LINGER THROUGH THE DAY IN THE VICINITY OF BJI,
ALTHOUGH THE BULK OF SNOW SHOULD REMAIN NORTH OF BJI.
WINDS WILL REMAIN LIGHT THROUGH THE ENTIRE TAF PERIOD WITH THE
BULK OF PREDOMINANT MVFR CEILINGS REMAINING MORE WEST OF OUR TAF
SITES. THAT SAID, DVL AND FAR MAY FALL TO MVFR IF THE STRATUS
DECK IS FURTHER EAST THAN FORECAST, SO KEEP THAT IN MIND.
