AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
432 AM CST FRI MAR 6 2026
KEY MESSAGES
- FREEZING DRIZZLE WILL PUSH EAST THRU THE AREA TODAY...WITH A
PERIOD OF LIGHT SNOW POSSIBLE THIS EVENING INN WEST CENTRAL
MINNESOTA.
- CHANCE FOR LIGHT SNOW ON TUESDAY.
UPDATE
ISSUED AT 424 AM CST FRI MAR 6 2026
GFS HAS FINALLY CAUGHT ON TO THE OTHER MODELS IN THAT
PRECIPITATION TODAY INTO THIS EVENING WILL BE LIGHT, WITH
GENERALLY A TRACE TO A FEW HUNDREDTHS OF ICING AND FOR MOST
TRACE AMOUNTS OF SNOW THRU THE DAY. ANY ICING WILL MAKE SURFACES
SLICK.
THE MAIN CHALLENGE TODAY IN UPDATES IS TIMING OF FRONT AND
COLDER AIR EASTWARD AND PTYPE. THE COLD FRONT WILL MOVE INTO OUR
FAR EAST AND SOUTHEAST FCST AREA LIKELY 15-17Z. PERIOD OF
FREEZING DRIZZLE BEHIND THE FRONT, THEN ENDS AS A BIT OF LIGHT
SNOW OR FLURRIES. THIS EVENING AS MOITURE FROM THE SOUTHWEST
DOES MOVE INTO CENTRAL, EASTERN AND SOUTHERN MINNESOTA THERE IS
STILL A CHANCE FOR A PERIOD OF LIGHT SNOW ALONG SOUTH OF
BEMIDJI- DETROIT LAKES- WAHPETON WITH LESS THAN 1 INCH OF
ACCUMULATION.
DID UPDATE WSW...KEPT ENDING TIMES AS IS, ONLY CHANGE WAS TO
SEPARATE OUT FAR EAST/SOUTHEAST TO START ADVISORY AT 15Z AS
STILL WARM AS OF 10Z IN THAT AREA.
DISCUSSION
ISSUED AT 120 PM CST THU MAR 5 2026
..SYNOPSIS
19Z SURFACE ANALYSIS THIS AFTERNOON SHOWS THE CENTER OF A LOW
PRESSURE BETWEEN BISMARCK AND CENTRAL SOUTH DAKOTA. A WARM FRONT
SITS ATTACHED TO THIS AND APPEARS ROUGHLY STRETCHED ACROSS THE
SHEYENNE RIVER VALLEY. EAST OF THIS FRONT, TEMPERATURES RANGE IN
THE 30S TO LOW 40S WHILE WEST OF THE FRONT, TEMPERATURES ARE
COOL IN THE TEENS AND LOW 20S. THIS FRONT WILL CONTINUE TO
PROPAGATE WESTWARD THIS AFTERNOON WITH FOG ONGOING AROUND IT.
GENERALLY SPEAKING, THE SYNOPTIC PATTERN WILL BE LARGELY DRIVEN
BY THE CURRENT CUTOFF LOW OVER THE DESERT SOUTHWEST WHICH WILL
CONTINUE TO OSCILLATE IN LOCATION OVER THE NEXT WEEK. THIS WILL
RESULT IN CONTINUED SPLIT FLOW OVER US. VERY LOW PREDICTABILITY
EXISTS WITH THE EVOLUTION OF THIS CUTOFF LOW, BUT AT A MINIMUM
THERE IS LARGE ENSEMBLE CONSISTENCY IN LARGELY WESTERLY FLOW
ALOFT WITH INTERMITTENT JET STREAKS EMBEDDED WITHIN THE FLOW.
WHILE THE CUTOFF CONTINUES TO GO ON ITS OWN DOWN SOUTH, WE WILL
LIKELY SEE PERIODIC CHANCES FOR ACTIVE WEATHER. REGRETTABLY, THE
TEMPERATURE GRADIENT THAT WILL SET UP ON TOP OF US AND LARGELY
ZONAL FLOW DOES LEAVE US SUSCEPTIBLE TO POTENTIAL FRONTOGENETIC
BANDING. AGAIN, PREDICTABILITY IS VERY LOW IN ANY IMPACTS SO
STAY TUNED FOR FUTURE FORECASTS.
..FOG TODAY
THE WARM FRONT CONTINUES TO BE THE MAIN FOCAL POINT FOR
ADVECTION FOG THROUGH THE DAY. THIS WILL CONTINUE TO PUSH WITH
THE FRONT WESTWARD THROUGH THE REMAINDER OF THE AFTERNOON.
OBSERVATIONS INDICATE LARGELY INTERMITTENT 1/4SM VISIBILITIES,
HOWEVER GIVEN THE HIGH PREDICTABILITY FOR 1/4SM FOG AND
PERSISTENCE EXCEEDING SEVERAL HOURS, A DENSE FOG ADVISORY WAS
ISSUED. DISPERSED BETWEEN FOG, FREEZING DRIZZLE HAS BEEN
OBSERVED AND IS LARGELY EXPECTED TO CONTINUE THROUGH THE
AFTERNOON AS WARM AIR ADVECTION REMAINS VERY STRONG OVER US.
WHILE THE CURRENT DENSE FOG ADVISORY GOES UNTIL 6 PM, FOG IS
EXPECTED TO CONTINUE THROUGH THE EVENING HOURS. THE MAIN REASON
FOR THE EXPIRATION AT 6 PM IS TO AVOID OVERCOMPLICATING
HEADLINES, AS FREEZING RAIN WILL EVENTUALLY BECOME THE LARGEST
THREAT THIS EVENING.
..FREEZING RAIN THROUGH TONIGHT/TOMORROW
THE MAIN WEATHER IMPACT FOR THE NEXT 24-48 HOURS WILL BE
FREEZING DRIZZLE AND FREEZING RAIN. THIS AFTERNOON, LARGE SCALE
STRONG WARM AIR ADVECTION IS CONTRIBUTING TO ONGOING FREEZING
DRIZZLE ACROSS NORTHEAST NORTH DAKOTA. AS THE WARM FRONT
PROPAGATES WESTWARD, THE EXPECTATION IS FOR FREEZING DRIZZLE TO
BE TAKEN WITH IT. HOWEVER, AS A WAVE COMING IN FROM NORTHERN
MONTANA APPROACHES, THE WARM FRONT IS EXPECTED TO STALL AND
EVENTUALLY BECOME A COLD FRONT, FORCING EASTWARD PROPAGATION.
WITH THE INCREASED FORCING FOR ASCENT FROM THE SYNOPTIC WAVE,
PRECIPITATION IS EXPECTED TO BECOME MUCH MORE WIDESPREAD.
THERMAL PROFILES WILL BE VARIABLE CAUSING DIFFERENT
PRECIPITATION TYPES BASED ON LOCATION. SURFACE TEMPERATURES
AROUND THE DEVILS LAKE BASIN SHOULD REMAIN WELL BELOW FREEZING
DESPITE TEMPERATURES ALOFT ACHIEVING ABOVE FREEZING. THIS
CREATES A PROFILE FAVORABLE FOR WIDESPREAD FREEZING RAIN. AREAS
WITHIN THE ABOVE FREEZING AREA ARE MORE LIKELY TO SEE RAIN. THIS
SWATH OF PRECIPITATION WILL PROPAGATE EASTWARD WITH THE FREEZING
RAIN AREA SLOWLY BEING OVERTAKEN BY COLDER AIR, THUS ALLOWING
FOR A TRANSITION TO SNOW. UNFORTUNATELY, MODEL GUIDANCE IS ALL
OVER THE PLACE WITH WHEN THIS TRANSITION OCCURS, SO A WINTER
WEATHER ADVISORY WAS ISSUED FOR FREEZING RAIN CONCERNS. THERE IS
VERY LITTLE CONCERN AT THIS TIME WITH REGARDS TO SNOW POTENTIAL
AS IT APPEARS THAT THE STRONG WARM NOSE WILL LARGELY INHIBIT ANY
SIGNIFICANT ACCUMULATING SNOWFALL. HAZARDOUS TRAVEL CONDITIONS
ARE EXPECTED TO DEVELOP WITH THIS FREEZING RAIN SO USE CAUTION
WHEN OUT TRAVELING TONIGHT.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 1136 PM CST THU MAR 5 2026
TAFS REMAIN A CHALLENGE THROUGH FRIDAY. A FEW POCKETS OF VFR
HAVE APPEARED LATE THIS EVENING, SETTING UP RIGHT OVER KFAR AND
KTVF. ANY VFR POCKETS SHOULD FILL IN OVER THE NEXT COUPLE OF
HOURS, WITH IFR TO LIFR RETURNING. FZDZ AND -FZRA WILL EXPAND IN
COVERAGE OVER THE NEXT 3 TO 6 HOURS, IMPACTING MOST TERMINALS AT
SOME POINT EITHER TONIGHT OR FRIDAY MORNING. PRECIPITATION
TRANSITIONS TO SNOW AS IT PUSHES OFF TO THE EAST. THERE REMAINS
SIGNIFICANT UNCERTAINTY IN THE DURATION OF PRECIPITATION INTO
FRIDAY AFTERNOON. RIGHT NOW, MAINTAINED A PERIOD OF -SN AT KFAR,
KTVF AND KBJI, BUT UNCERTAIN IF THIS WILL ACTUALLY HAPPEN FOR
THE DURATION OF THE INDICATED PERIOD, OR RATHER BE A MUCH
BRIEFER OCCURRENCE. CEILINGS WILL GENERALLY IMPROVE FROM WEST
TO EAST FRIDAY AFTERNOON AND EVENING, WITH MVFR BY THE END OF
THE TAF PERIOD AT MOST TERMINALS.
