SHORT TERM /THROUGH TUESDAY NIGHT/
ISSUED AT 223 PM EDT MON OCT 13 2025
PATTERN SYNOPSIS/FORECAST: EARLY THIS AFTERNOON, CLOSED UPPER-LEVEL
LOW PRESSURE SITS NEAR THE MANITOBA/ONTARIO BORDER WITH ATTENDANT
SFC LOW PRESSURE NEARING HUDSON BAY. ASSOCIATED COLD FRONT DRAPED TO
THE SOUTH ACROSS NORTHERN ONTARIO, THE CENTRAL U.P. INTO EASTERN WI.
THIS BOUNDARY WILL MAKE SLOW EASTWARD PROGRESS ACROSS NORTHERN MI
EARLY THIS EVENING THROUGH TONIGHT ACCOMPANIED BY DECAYING SHOWER
CHANCES.
IN THE WAKE OF THIS SYSTEM, UPPER-LEVEL HEIGHTS BUILD WITH UPSTREAM
SFC HIGH PRESSURE SETTLING IN ACROSS THE UPPER MS VALLEY AND
NORTHERN GREAT LAKES ON TUESDAY. BY TUESDAY NIGHT, LOW PRESSURE
BEGINS TO SHOW SIGNS OF MATERIALIZING LEE OF THE ROCKIES WITH A
DEVELOPING WARM FRONT STRETCHED FROM THE PLAINS INTO THE MID-MS
VALLEY. INCREASED ISENTROPIC ASCENT NORTH OF THIS BOUNDARY, DESPITE
PALTRY MOISTURE, MAY YIELD ANOTHER LOW END SHOWER CHANCE TUESDAY
NIGHT.
FORECAST DETAILS: AS EXPECTED, SHOWERS REALLY STRUGGLING WITH
EASTWARD EXTENT ACROSS NORTHERN MI SO FAR TODAY, WITH THE PRIMARY
AXIS OF ANY SHOWER ACTIVITY HAVING BEEN STUCK UPSTREAM OVER PARTS OF
NORTHEAST WI AND CENTRAL U.P. WHILE SHOWER CHANCES DO GRADUALLY
BUILD FARTHER EAST INTO PARTS OF NORTHERN LOWER AND EASTERN
UPPER THROUGH THE REMAINDER OF THE AFTERNOON AND EVENING, NOT
REALLY APPEARING TO BE MUCH HOPE FOR MEANINGFUL RAIN AMOUNTS.
OTHERWISE, WINDS TURN NORTHWESTERLY POST FROPA TONIGHT WITH LOWS
LARGELY IN THE 40S AREA-WIDE. SOME LOW PROBABILITIES FOR AT
LEAST PATCHY FOG ONCE AGAIN, BUT HIGHLY DEPENDENT ON OVERNIGHT
CLOUD TRENDS AND THE ABILITY FOR WINDS TO DECOUPLE AFTER VEERING
OUT OF THE NORTHWEST.
ANY TUESDAY MORNING FOG/STRATUS SHOULD AGAIN GRADUALLY BURN OFF/MIX
OUT WITH PARTLY SUNNY SKIES ANTICIPATED BY TUESDAY AFTERNOON. HIGH
TEMPS EXPECTED TO BE A GOOD 10+ DEGREES COOLER THAN TODAY IN MANY
AREAS -- LARGELY SPANNING THE 50S -- SAVE FOR SOME LOW-MID 60S
CREEPING IN NEAR SAGINAW BAY.
LONG TERM /WEDNESDAY THROUGH MONDAY/
ISSUED AT 223 PM EDT MON OCT 13 2025
DAY 3-4 (WEDNESDAY - THURSDAY):
HIGH PRESSURE LARGELY IN CONTROL THROUGH THE MIDWEEK TIMEFRAME.
PLENTY OF SUNSHINE ANTICIPATED WEDNESDAY WITH HIGHS IN THE 50S.
CHILLY WEDNESDAY NIGHT WITH GROWING PROBABILITIES FOR SOME OF THE
TYPICALLY COLDER ICEBOX LOCATIONS TO FALL TO NEAR 20 F FOR A LOW
TEMP WEDNESDAY NIGHT/THURSDAY MORNING.
WINDS TURN OUT OF THE SOUTH THURSDAY WITH DAYTIME HIGHS REBOUNDING A
HANDFUL OF DEGREES. INCREASING CLOUDS TO BE THE RULE, ESPECIALLY LATE
IN THE DAY, IN ADVANCE OF ANOTHER ROUND OF ISENTROPICALLY DRIVEN
PRECIP THAT MAY CROSS THE AREA THURSDAY NIGHT.
DAY 5-7 (FRIDAY - SUNDAY): BY LATE IN THE WEEK, LOW PRESSURE IS
EXPECTED TO BE SITUATED NEAR THE MANITOBA/ONTARIO BORDER WITH
THURSDAY NIGHT'S WARM FRONT POSITIONED WELL TO THE NORTH. TEMPS
CREEP UP ANOTHER FEW DEGREES FOR FRIDAY BEFORE ANOTHER ROUND OF
SHOWERS AND EVEN A FEW RUMBLES OF THUNDER BECOMES INCREASINGLY
LIKELY SATURDAY AS A COLD FRONT MAKES HEADWAY WEST TO EAST ACROSS
THE GREAT LAKES. COOLER AGAIN BEHIND THAT BOUNDARY WITH POTENTIAL
FOR LAKE EFFECT/ENHANCED RAIN SHOWERS TO WRAP UP THE TAIL END OF THE
WEEKEND.
AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/
ISSUED AT 736 PM EDT MON OCT 13 2025
SLOW MOVING, WEAK FRONT DRAPED FROM SW WI TO THE CENTRAL U.P. THIS
EVENING TO SLOWLY PIVOT DOWN INTO NORTHERN LOWER MI WITH TIME
TONIGHT...AND EXPECT WIND SHIFT FROM LIGHT AND VARIABLE TO NW 5-10KTS
BETWEEN 03-08Z STARTING AT CIU FIRST; COULD GUST AS HIGH AS 15-
20KTS WITH THE FRONT BUT LEFT THIS IDEA OUT FOR NOW. LIGHT/ISOLATED
SHRA AND/OR -DZ THROUGH ABOUT 4-6Z WITH A DIP TO MVFR CIGS WITH THE
FRONT OVERHEAD; SHRA/DZ MORE LIKELY AT CIU AND PLN. DO STILL HAVE
CONCERNS ABOUT FOG TONIGHT AT ALL SITES DESPITE FRONT DROPPING THRU,
AND HAVE THIS IDEA IN THE TAFS AGAIN...BOTH EARLY ON THIS EVENING
AND AGAIN BEHIND THE FRONT OVERNIGHT, BUT NOT SURE IT WILL BE AS
MUCH AS LAST NIGHT. LOW MOISTURE TO MIX OUT IN THE MORNING WITH
15KFT+ CLOUD DECK SLIDING OVERHEAD THROUGH THE DAY; THINK SOME
DAYTIME CUMULUS (BASES AROUND 2-5KFT) WILL DEVELOP DURING THE DAY
THOUGH. WINDS STAY UP FROM THE N THROUGH THE AFTERNOON.
