PRECIPITATION TO PARTS OF NORTHERN MI THIS WEEKEND.

DISCUSSION
ISSUED AT 135 PM EDT FRI MAR 20 2026
PATTERN SYNOPSIS/FORECAST: EARLY THIS AFTERNOON, DOWNSTREAM
TROUGHING SITUATED OVER THE EASTERN SEABOARD WITH EXPANSIVE RIDGING
UPSTREAM OVER THE WESTERN THIRD OF THE CONUS. THIS MORNING'S CLIPPER
NOW WELL OFF TO THE EAST WITH ATTENTION TURNING TO ENERGY MAKING
HEADWAY INTO THE BRITISH COLUMBIA/PACIFIC NORTHWEST. UPSTREAM RIDGING
FLATTENS WITH TIME EARLY THIS WEEKEND WITH THAT UPSTREAM ENERGY SET
TO RIDE NEAR THE INTERNATIONAL BORDER INTO THE GREAT LAKES THIS
WEEKEND. INTO NEXT WEEK, A RELATIVELY ACTIVE PATTERN REMAINS IN
PLACE WITH SEVERAL ADDITIONAL CHANCES FOR PRECIPITATION THROUGH THE
END OF THE FORECAST PERIOD.
FORECAST DETAILS:
TEMPERATURES CONTINUE TO WARM ABOVE FREEZING AREA-WIDE TODAY, OF
COURSE TAKING LONGEST TO MODERATE ACROSS THE EASTERN U.P. (ANJ STILL
AT 31 AS OF 1:30 PM) WHILE THOSE ACROSS SOUTHERN REACHES OF THE
FORECAST AREA PROPEL THROUGH THE 40S. LOWS TONIGHT SET TO DROP BACK
BELOW FREEZING AREA-WIDE, BOTTOMING OUT IN THE 20S FOR MOST.
FOCUS TURNS TO THE WEEKEND AS OUR NEXT CLIPPER SYSTEM CROSSES
NORTHERN MI. INITIAL PRECIP CHANCES LOOK TO ARRIVE AS EARLY AS LATE
SATURDAY MORNING/MIDDAY, ESPECIALLY ACROSS THE EASTERN U.P. AND TIP
OF THE MITT. MORE LIKELY THAN NOT THIS INITIAL WARM ADVECTION WING
OF PRECIP FALLS AS PRIMARILY WET/DENSE SNOW WITH SOME LOCALIZED 1-4"
NOT OUT OF THE QUESTION ACROSS PARTS OF THE EASTERN U.P. THROUGH
EARLY SATURDAY EVENING. THIS SYSTEM SAGS SOUTH INTO NORTHERN LOWER
SATURDAY NIGHT INTO SUNDAY WITH INCREASING PRECIP CHANCES FARTHER
SOUTH WITH TIME, ALBEIT WITH INCREASING UNCERTAINTY REGARDING PRECIP
TYPE. LATEST TRENDS SUPPORT A RAIN/SNOW, PERHAPS FREEZING RAIN, MIX
ACROSS THE U.P. AND STRAITS, WITH THIS PERHAPS SNEAKING INTO THE TIP
OF THE MITT AND FAR NORTHEAST LOWER. PRIMARILY RAIN ANTICIPATED
SOUTH OF THESE AREAS WITH TEMPERATURES LATE SATURDAY NIGHT INTO
SUNDAY AT LEAST A COUPLE OF DEGREES ABOVE FREEZING. OVERALL, NOT A
WIDESPREAD IMPACT EVENT, BUT THERE'S ENOUGH THERE TO BE MONITORED
OVER THE NEXT COUPLE OF FORECAST CYCLES FOR POTENTIAL LOCALIZED
IMPACTS DUE TO SNOW/ICE ACROSS THE EASTERN U.P., STRAITS, AND
PERHAPS DOWN INTO THE TIP OF THE MITT AND PARTS OF NORTHEAST LOWER.
THIS WAVE LARGELY EXITS THROUGH THE DAY SUNDAY WITH BELOW NORMAL
TEMPERATURES EXPECTED SUNDAY NIGHT - MONDAY. LOWS SUNDAY NIGHT
FAVORED IN THE TEENS AND LOW 20S ACROSS THE AREA -- COLDEST IN THE
U.P. WHERE SOME LOCALIZED SINGLE DIGITS READINGS ARE POSSIBLE.
MONDAY'S HIGHS RANGING FROM THE UPPER 20S FAR NORTH TO THE UPPER 30S
NEAR SAGINAW BAY.
ADDITIONAL CHANCES FOR UNSETTLED WEATHER RETURN AS EARLY AS TUESDAY
NEXT WEEK AND CONTINUE AT TIMES THROUGH THE REMAINDER OF THE
FORECAST PERIOD AS LONGER RANGE TRENDS FAVOR SEVERAL ADDITIONAL
WAVES/CLIPPER SYSTEMS TRAVERSING THE NORTHERN TIER OF THE CONUS.

ISSUED AT 1126 PM EDT FRI MAR 20 2026
STILL EXPECTING SOME IFR/LIFR CIGS AND/OR VISBYS TONIGHT DUE TO
PATCHY FOG WITH LIGHT/VRB WINDS. LATEST DATA LOOKS A LITTLE SLOWER
WITH ONSET OF RAIN/SNOW...CLOSER TO 12-15Z FOR CIU/PLN; SOME
QUESTION IF IT REACHES THE GROUND AT TVC/MBL OR NOT, WITH A BETTER
CHANCE FOR CIGS TO GO MVFR/VFR AFTER 18Z BEHIND STRENGTHENING WARM
FRONT. COULD STAY ALL SN AT CIU WITH RASN MORE LIKELY FOR PLN/APN,
WITH SHOT AT ALL RA BY LATE AFTERNOON THERE...WITH MOST INTENSE
PERIOD CLOSER TO 18-0Z. SURFACE LOW COULD TRACK ACROSS THE
TVC/MBL AREA IN AFTERNOON WITH POTENTIAL FOR LIGHT WINDS IN
MIDDAY/LATE AFTERNOON...BUT OTHERWISE EXPECT PERIOD OF STRONGER
SE WINDS AHEAD OF THIS (5-15KT) AROUND 15-20Z, TURNING TO NE
TOWARD 21- 0Z. SOME LLWS POSSIBLE, ESP AT MBL LATE IN THE
DAY...BUT COULD BE FURTHER NORTH INTO TVC/APN IF LOW TRACKS
FURTHER NORTH.
