SOUTHEAST THROUGH THE OVERNIGHT AND MORNING HOURS.
- A MORE ACTIVE PATTERN CONTINUES INTO NEXT WEEK, BRINGING
ADDITIONAL OPPORTUNITIES FOR WINTER IMPACTS OVER PARTS OF THE
REGION. PREDICTABILITY IN IMPACTS REMAINS VERY LOW BEYOND
FRIDAY.
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 /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1119 AM CST THU MAR 5 2026
IFR TO LIFR CONDITIONS WILL CONTINUE TO PREVAIL FOR THE TAF
PERIOD, LARGELY AIDED BY FOG AND LOW CEILINGS. PATCHY DRIZZLE IS
POSSIBLE THIS AFTERNOON AS WELL, BUT THE BULK OF PRECIPITATION
WILL BEGIN AROUND 00Z AT DVL, EVENTUALLY SPREADING SOUTHEAST
THROUGH THE OVERNIGHT PERIOD. FZRA IS LIKELY TO OCCUR AT
GFK/TVF/FAR BEFORE TRANSITIONING OVER TO SNOW. MVFR VISIBILITIES
FROM PRECIPITATION ARE LIKELY WITH OCCASIONAL IFR, HOWEVER
FLIGHT CATEGORIES WILL REMAIN IFR/LIFR FROM CEILINGS.
PRECIPITATION WILL IMPROVE FROM NORTHWEST TO SOUTHEAST THROUGH
THE MORNING HOURS, ALTHOUGH SNOW IS LIKELY TO BE ONGOING BY THE
END OF THE TAF PERIOD FOR ALL TAF SITES EXCEPT DVL WHO WILL BE
DONE WITH PRECIPITATION.
WIND DIRECTIONS WILL REMAIN VARIABLE OVER THE NEXT SEVERAL HOURS
AS A WARM FRONT CONTINUES TO PUSH NORTHWEST. ON THE WARM SIDE OF
THE FRONT, SOUTHEASTERLY WINDS WILL OCCUR WHILE ON THE COLD SIDE
OF THE FRONT NORTHWESTERLY WINDS WILL OCCUR. THIS FRONT SHOULD
EVENTUALLY STALL BEFORE BEING KICKED BACK EAST. EVENTUALLY, ALL
TAF SITES WILL BEGIN TO EXPERIENCE NORTHWESTERLY WINDS AGAIN AS
THE FRONT MOVES THROUGH.
