LAST NIGHT'S CLIPPER IS EXITING NORTHEAST MINNESOTA THIS
AFTERNOON, BUT THE SOUTH SHORE REMAINS ACTIVE. A GRAVITY WAVE
HAS DEVELOPED EAST OF THE TWIN PORTS, BRINGING A SECONDARY ROUND
OF MODERATE SNOW TO DOUGLAS AND BAYFIELD COUNTIES THROUGH THE
REST OF THE DAY. SIMILAR CONDITIONS ARE PERSISTING FOR ASHLAND
AND IRON COUNTIES AS WINDS TURN TO THE NORTHWEST AND LAKE EFFECT
CONTINUES INTO THIS AFTERNOON AND EVENING. EXPECT DIFFICULT
TRAVEL IN THESE AREAS THROUGH THE EVENING HOURS.
WE WILL GET A BRIEF BREAK ON SATURDAY MORNING BEFORE THE NEXT
SIGNIFICANT SYSTEM ARRIVES. THE TRACK FOR THIS COLORADO HAS
SHIFTED ITS TRACK EVEN FURTHER NORTH, INCREASING CONFIDENCE
THAT MUCH OF NORTHWEST WISCONSIN WILL SEE A FOOT OR MORE OF SNOW
BY MONDAY MORNING. THE HIGHEST TOTALS, POTENTIALLY OVER 20
INCHES, ARE FORECAST FOR AREAS CLOSER TO CENTRAL WISCONSIN,
INCLUDING SAWYER AND PRICE COUNTIES. WHILE THE TRACK IS STILL A
BIT UNCERTAIN, THE POTENTIAL FOR HEAVY SNOW IN THESE AREAS IS
HIGH. STRONG WINDS OFF LAKE SUPERIOR COULD LEAD TO BLIZZARD-LIKE
CONDITIONS AS WELL ALONG THE SOUTH SHORE COMBINED WITH HEAVY
SNOWFALL RATES.
THE SHIFT NORTH ALSO MEANS HIGHER IMPACTS FOR THE TWIN PORTS AND
THE NORTH SHORE. LAKE SUPERIOR IS EXPECTED TO ENHANCE SNOWFALL
IN THESE AREAS, LEADING TO INCREASED CONFIDENCE IN OVER 6 INCHES
OF ACCUMULATION EVEN ON THE NORTHERN FRINGE OF THE STORM.
HOWEVER, IF THIS SYSTEM WERE TO SHIFT BACK SOUTH DUE TO THE
TRACK CHANGING FROM MODEL RUN TO MODEL RUN, THESE TOTALS COULD
DECREASE SIGNIFICANTLY ONCE AGAIN.
WINDS WILL GUST TO 35 MPH, LEADING TO BLOWING SNOW AND LOW
VISIBILITY WHERE MODERATE TO HEAVY SNOW OCCURS. AND THOUGH
BLOWING SNOW WILL LINGER AFTER THIS SYSTEM AS WELL, IT WILL NOT
BE QUITE AS INTENSE AS THE CLIPPER THAT PASSED YESTERDAY.
SNOW WILL FINALLY TAPER OFF ON SUNDAY NIGHT, THOUGH LAKE EFFECT
WILL CONTINUE TO LINGER ALONG THE SOUTH SHORE THROUGH MOST OF
MONDAY, ESPECIALLY IN ASHLAND AND IRON COUNTIES.
FOLLOWING THE STORM, A SURGE OF ARCTIC AIR WILL DROP WIND
CHILLS TO NEAR 20 BELOW ZERO ON MONDAY AND TUESDAY MORNINGS.
LOOKING AHEAD, A WEAK SYSTEM MOVES THROUGH MID-WEEK BEFORE A
WARM AIR MASS BRINGS MUCH MILDER TEMPERATURES IN THE 40S FOR THE
LATTER HALF OF NEXT WEEK.
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
ISSUED AT 1222 AM CDT SAT MAR 14 2026
VFR CONDITIONS EXPECTED MUCH OF THE TAF. WINDS LESS THAN 10KTS
OVERNIGHT WILL TURN TO THE EAST/SOUTHEAST SATURDAY AHEAD OF THE
NEXT STORM SYSTEM. THAT SYSTEM ARRIVES SATURDAY EVENING, WITH
LIGHT SNOW AND DECREASING CIGS ARRIVING AT BRD AND HYR AFTER
15/00Z. EXPECT MVFR CIGS AND REDUCED VIS, WITH CONDITIONS
DETERIORATING BEYOND THIS FORECAST PERIOD AS SNOWFALL BECOMES
MODERATE TO HEAVY.
MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/
ISSUED AT 322 PM CDT FRI MAR 13 2026
A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR ALL NEARSHORE
WATERS THROUGH LATE THIS EVENING. NORTHWEST WINDS WILL GUST TO
30 KNOTS THIS AFTERNOON BEFORE EASING TONIGHT. QUIET CONDITIONS
PREVAIL ON SATURDAY, BUT ANOTHER STRONG SYSTEM ARRIVES SATURDAY
NIGHT. EXPECT NORTHEAST WINDS TO RAMP UP QUICKLY AFTER MIDNIGHT
WITH GALES LIKELY ON SUNDAY. A GALE WATCH IS IN EFFECT FOR ALL
OF WESTERN LAKE SUPERIOR WATERS.
