ISSUED AT 139 AM EDT WED MAY 6 2026
AS WE REMAIN UNDER THE INFLUENCE OF POLAR/CANADIAN AIR THE REST OF
THIS WEEK, EXPECT BELOW NORMAL TEMPERATURES (SIMILAR TO WHAT WE SAW
YESTERDAY AND WHAT WE ARE SEEING EARLY THIS MORNING) TO CONTINUE FOR
THE NEXT FEW DAYS. IN ADDITION, WITH WEAK SHORTWAVE IMPULSES
ROUNDING THROUGH THE REGION AS SFC PRESSURE CONTINUES TO RISE ACROSS
OUR AREA, EXPECT TO SEE SOME SCATTERED DIURNAL RAIN/SNOW SHOWERS
ACROSS THE U.P. TODAY, THURSDAY, AND POTENTIALLY EVEN FRIDAY AS
WELL. THANKFULLY, NO SNOWFALL ACCUMULATIONS ARE EXPECTED AS THE
TEMPERATURES AND GROUND SHOULD BE TOO WARM FOR ANYTHING TO STICK.
NEVERTHELESS, SOME SPOTS MAY SEE UP TO A TRACE OF SNOWFALL ON THE
GRASSY SFCS IN THE HEAVIEST SNOW SHOWERS BEFORE THE WARM AIR AND
GROUND MELTS THE PRECIPITATION.
IN ADDITION TO THE SHOWER CHANCES, THE AIR AT THE SFC LOOKS TO BE
QUITE DRY GIVEN THE INCOMING SFC RIDGING FROM THE CANADIAN PRAIRIES
THE MIDDLE OF THIS WEEK. THUS, WHILE TEMPERATURES ARE PROJECTED TO
ONLY GET INTO THE 40S AND 50S DURING THE DAYTIME, WITH DEWPOINTS
EXPECTED TO BE WELL BELOW FREEZING THROUGHOUT THE NEXT FEW DAYS, MIN
RHS DURING THE AFTERNOON HOURS COULD DIP BELOW 30% IN THE INTERIOR
AREAS TODAY AND WELL INTO THE 20 PERCENTS THURSDAY AND FRIDAY.
THANKFULLY, BECAUSE THE WINDS ARE LOOKING TO REMAIN LIGHT THROUGHOUT
THE NEXT SEVERAL DAYS AND THE TEMPERATURES ARE LOOKING TO STAY BELOW
NORMAL (SAVE FOR POTENTIALLY FRIDAY AND SATURDAY), ELEVATED FIRE
WEATHER CONCERNS ARE NOT EXPECTED.
WITH WARM AIR ADVECTION MOVING IN ON FRIDAY AHEAD OF A COLD FRONT
DESCENDING FROM CANADA, EXPECT THE HIGHS TO BE CLOSER TO NORMAL,
MAINLY IN THE 50S TO LOWER 60S. AS THE COLD FRONT MOVES THROUGH THE
U.P. FRIDAY NIGHT AND SATURDAY, EXPECT RAIN SHOWERS TO PUSH THROUGH
THE AREA, WITH AROUND NORMAL TEMPERATURES CONTINUING THROUGH THE DAY
SATURDAY. WHILE NOT MUCH LIQUID IS EXPECTED FROM THE RAIN SHOWERS
VIA THE COLD FRONT, A FEW SPOTS MAY BE 'LUCKY' AND GET A WETTING
RAINFALL (A TENTH TO QUARTER OF AN INCH).
BEHIND THE COLD FRONT, EXPECT MORE HIGH PRESSURE DESCENDING FROM THE
CANADIAN PRAIRIES TO BRING DRY WEATHER AND COOLER THAN NORMAL
CONDITIONS BACK ACROSS THE U.P. EARLY NEXT WEEK. YET EVEN SO, THE
HIGH PRESSURE BLOCK THAT'S SETTLED OVER THE PACIFIC NORTHWEST THIS
WEEK BEGINS TO PROGRESS EASTWARD OVER THE CONUS NEXT WEEK. AS THIS
OCCURS, WE MAY SEE A TREND TOWARDS MORE NORMAL TEMPERATURES AND
POTENTIALLY EVEN WETTER CONDITIONS NEAR THE END OF THE FORECAST
PERIOD (THE MIDDLE OF NEXT WEEK) AS STRONGER SHORTWAVE OR TWO COULD
IMPACT THE AREA.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 104 AM EDT WED MAY 6 2026
MAINLY VFR CONDITIONS ARE EXPECTED ACROSS THE TAF SITES TODAY,
ALTHOUGH SOME MVFR CONDITIONS COULD BE REALIZED AT SAW THIS
AFTERNOON AS DIURNAL SHOWERS MOVE OVERHEAD. EXPECT THE WINDS TO BE
FAIRLY LIGHT FROM THE W/NW (AND N OVER SAW) TODAY INTO THIS EVENING.
MARINE
ISSUED AT 139 AM EDT WED MAY 6 2026
LIGHT WINDS OF GENERALLY 20 KNOTS OR LESS CONTINUES THE REST OF THIS
WEEK INTO THIS WEEKEND AS A STOUT HIGH PRESSURE RIDGE OVER THE
PACIFIC NORTHWEST HELPS KEEP THE WEATHER OVER THE UPPER GREAT LAKES
MOSTLY QUIET THE NEXT SEVERAL DAYS. NEVERTHELESS, A SHOT OF COLD AIR
ADVECTION COMING DOWN ON SUNDAY COULD BRING NORTHWEST WINDS OF 20 TO
25 KNOTS BACK ACROSS THE EASTERN HALF OF THE LAKE TO BEGIN NEXT
WEEK.
