DISCUSSION
ISSUED AT 148 PM EDT SUN MAR 8 2026
PATTERN SYNOPSIS/FORECAST:
ELONGATED AND RATHER INTENSE WEST/EAST ORIENTED UPPER LEVEL JET
SPANNING THE FULL LENGTH OF THE NORTHERN CONUS EARLY THIS AFTERNOON,
LOCKING ANY REAL COLD AIR NORTH OF THE BORDER AND FLOODING THE
REGION WITH MUCH MODIFIED PACIFIC ORIGINATED AIR. RATHER ROBUST
NORTH/SOUTH PRESSURE GRADIENT BETWEEN SUB 980MB LOW PRESSURE RACING
EAST ACROSS NORTHERN ONTARIO AND HIGH PRESSURE WELL TO OUR SOUTH
KICKING OFF SOME RATHER GUSTY SOUTHWEST WINDS ACROSS THE NORTHERN
LAKES, WITH WIND GUSTS OFTEN EXCEEDING 30 MPH. THOSE WINDS ONLY
HELPING INDUCE FURTHER WARMING IN AN ALREADY VERY MILD OVERHEAD
AIRMASS, WITH CURRENT READINGS ACROSS THE NORTHWOODS MOSTLY IN THE
40S...A GOOD 10 OR MORE DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR.
AIRMASS ONLY FURTHER MODIFIES THROUGH MONDAY AS GUSTY SOUTHWEST
WINDS CONTINUE. HOWEVER, CHANGES ARE A'LURKING...WITH THOSE EVENTUAL
CHANGES DRIVEN BY FAST MOVING SHORTWAVE TROUGH AND INTENSE UPPER JET
CORE EXPECTED TO ENTER THE PACIFIC NORTHWEST LATER ON MONDAY. THIS
WAVE WILL AMPLIFY WITH TIME AS IT RACES EAST ACROSS THE NORTHERN
CONUS, DRUMMING UP INTENSIFYING LOW PRESSURE ACROSS THE REGION THE
MIDDLE OF THIS WEEK. COUPLE THAT WITH A SOUTHWARD DRIFTING MUCH
COOLER AIRMASS AND THE STAGE IS SET FOR PERHAPS AN IMPACTFUL WINTER
WEATHER EVENT TUESDAY NIGHT INTO WEDNESDAY. STRONG SUPPORT FOR YET
ANOTHER SHARP SHORTWAVE TROUGH/REINFORCING SHOT OF UPPER JET
DYNAMICS TO ARRIVE TO END THE WEEK...VISITING OUR AREA IN WHAT BY
THEN WILL BE A MUCH MORE TYPICAL MID-MARCH AIRMASS...AGAIN SETTING
THE STAGE FOR PERHAPS MORE IMPACTFUL WINTER WEATHER.
PRIMARY FORECAST CONCERNS:
JUST HOW WARM TO GO WITH TEMPERATURES ON MONDAY, WITH FOCUS THE
QUICKLY SHIFTING TO THAT POTENTIALLY MESSY WINTER WEATHER LATER
TUESDAY INTO WEDNESDAY. WILL ALSO BRIEFLY ADDRESS POTENTIAL FOR LATE
WEEK SNOWS.
DETAILS:
COULD SIMPLY NOT GET MUCH MORE OF A PERFECT EARLY SPRING ENVIRONMENT
TO SUPPORT WELL ABOVE NORMAL TEMPERATURES TONIGHT INTO MONDAY WITH
MAINTENANCE OF THOSE GUSTY SOUTHWEST WINDS WITHIN AN INCREASINGLY
WARM OVERHEAD AIRMASS. LOOKING AT LOWS TONIGHT ONLY DROPPING INTO
THE MIDDLE 30S TO LOWER 40S. FORCED MECHANICAL MIXING FROM THE GUSTY
WINDS AND PLENTY OF SUNSHINE WITHIN SUCH A MILD ENVIRONMENT EASILY
SUPPORTS HIGHS IN THE 50S AND 60S SOUTH OF THE BIG BRIDGE ON MONDAY,
WITH READINGS MOSTLY IN THE UPPER 40S ACROSS EASTERN UPPER MICHIGAN.
COULD SEE A FEW RECORDS CHALLENGED OR BROKEN ON MONDAY, ESPECIALLY
AT HOUGHTON LAKE AND TRAVERSE CITY WHERE FORECAST HIGHS IN THE LOWER
TO MIDDLE 60S ARE EXPECTED (RECORDS OF 58 AND 60 RESPECTIVELY)
SECONDARY STORY CENTERS ON SMALL RAIN CHANCES TONIGHT ON THE LEADING
NOSE OF THAT INTENSIFYING WARM AIR ADVECTION. OTHERWISE, LOOKING AT
DRY CONDITIONS TROUGH MONDAY NIGHT.
STILL VERY MILD AND LARGELY UNEVENTFUL THROUGH MUCH OF TUESDAY.
HOWEVER, FORECAST BECOME SUBSTANTIALLY MORE CHALLENGING HEADING INTO
TUESDAY NIGHT WITH THAT DEVELOPING LOWER LAKES LOW PRESSURE AND
SOUTHWARD SAGGING COLD AIR. WHILE COLD AIR ADVECTION AT THE SURFACE
INTENSIFIES WITH INCREASING NORTHEAST WINDS, OFF THE DECK THERMAL
PROFILES ARE A BIT SLOW TO RESPOND AS SOUTHWEST FLOW CONTINUES AT
THOSE ELEVATED LEVELS. THIS SETS THE STAGE FOR A WINTRY MIX OF
FREEZING RAIN AND SLEET TO BUILD SOUTH ACROSS NORTHERN LOWER
MICHIGAN TUESDAY NIGHT, WITH A WINTRY MIX TURNING TO SNOW WITH TIME
ACROSS EASTERN UPPER MICHIGAN. POTENTIAL FOR SECONDARY AREA OF LOW
PRESSURE TO WORK NORTHEAST UP THE SOUTHWARD SAGGING BAROCLINIC AXIS
SUPPORTS SNOW SPREADING ACROSS AT LEAST PORTIONS OF NORTHERN LOWER
MICHIGAN DURING THE DAY WEDNESDAY AS WELL. DEFINITELY NOT SOLD AT
ALL ON HOW IMPACTFUL THIS EVENT WILL BECOME, WITH AT LEAST SOME
EVIDENCE PRECIPITATION SHIELD REMAINS DISJOINTED AT BEST, WITH FULL
DEFORMATION AND TROWAL DYNAMICS NOT MATURING UNTIL THE SYSTEM IS
WELL NORTHEAST OF OUR AREA. THIS UNCERTAINTY REMAINS EVIDENT IN
LATEST STATISTICAL CALCULATIONS, WITH PROBABILITIES OF A TENTH OF AN
INCH OR MORE OF FREEZING RAIN AT OR BELOW 50 PERCENT ACROSS NORTHERN
LOWER MICHIGAN, WITH SNOW PROBABILITIES IN EXCESS OF 3 INCHES
REMAINING UNDER 40 PERCENT RIGHT THROUGH WEDNESDAY ACROSS ALL OF THE
AREA. GIVE SUCH REMAINING UNCERTAINTIES, BEST COURSE OF ACTION IS TO
AVOID ANY SPECIFIC WINTER RELATED HEADLINES JUST YET, UTILIZING OUR
GRAPHICS AND HAZARDOUS WEATHER TEXT PRODUCT TO HIGHLIGHT THIS WINTER
WEATHER POTENTIAL.
DEFINITELY COOLER TO END THE WEEK ON INTO THE WEEKEND WITH MUCH MORE
CANADA ORIGINATED AIRMASS CONTRIBUTION...LIKELY KEEPING HIGHS MOSTLY
IN THE 30S. AS MENTIONED EARLIER, WILL HAVE TO WATCH TRENDS FOR A
SYSTEM TO VISIT OUR AREA TO END THIS WORK WEEK...WITH AT LEAST SOME
INDICATION THIS COULD BE A FAIRLY WRAPPED UP AND INTENSE LOW
PRESSURE. MUCH TOO EARLY FOR SPECIFICS, BUT SOMETHING TO MONITOR AS
WE HEAD THROUGH THIS WEEK...ESPECIALLY WITH WHAT SHOULD BE MUCH
COOLER THERMAL PROFILES BY THEN.
