NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jun 4, 3:08 AM EST, 1 hour 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 408 AM EDT SAT JUN 4 2011 .SYNOPSIS.../ISSUED AT 408 AM/ LOW PRESSURE OVER HUDSON BAY WILL SLOWLY LIFT NORTH TODAY...WITH A COLD FRONT PUSHING THROUGH THE REGION INTO THE AFTERNOON. THIS FRONT WILL PROVIDE THE FOCUS FOR SHOWERS AND THUNDERSTORMS FOR MUCH OF NORTHERN MICHIGAN THROUGH MID MORNING...BEFORE APPROACHING HIGH PRESSURE FROM THE UPPER MIDWEST BRINGS A RETURN TO DRY WEATHER INTO THE LATE AFTERNOON AND EVENING. THIS HIGH WILL CROSS THE AREA INTO SUNDAY...WITH PLENTY OF SUNSHINE AND PLEASANT TEMPERATURES...BEFORE INCREASING HEAT AND HUMIDITY INTO EARLY NEXT WEEK BRINGS BACK SMALL CHANCES FOR AFTERNOON SHOWERS AND THUNDERSTORMS. DL && .SHORT TERM.../ISSUED AT 408 AM/...TODAY OVERNIGHT SFC ANALYSIS REVEALS LOW PRESSURE TRACKING NORTHEASTWARD TOWARD HUDSON BAY...AND TRAILING COLD FRONT EXTENDS SOUTH ACROSS WESTERN LAKE SUPERIOR AND THROUGH WISCONSIN. AHEAD OF THE FRONT...NICE LOW LEVEL THERMAL/MOISTURE AXIS NOSING INTO NORTHERN MICHIGAN. CONVERGENCE ALONG THE FRONT COMBINED WITH A STOUT LOW LEVEL JET ACTING HAS FIRED OFF A WANNABE THUNDERSTORM COMPLEX OVER LAKE SUPERIOR DURING THE NIGHT...WHICH WILL BE IMPACTING A PORTION OF THE CWA...MAINLY EASTERN UPPER MICHIGAN...THIS MORNING. THIS MORNING...SMALL THUNDERSTORM COMPLEX WILL BE ROLLING THROUGH THE FAR NORTHERN PART OF THE CWA EARLY THIS MORNING...AND WILL NEED TO CARRY CATEGORICAL POPS ACROSS MOST OF EASTERN UPPER MICHIGAN IN THE EARLY GOING. STILL SOME QUESTIONS OVER HOW MUCH OF A SOUTHWARD TURN THIS SMALL COMPLEX MAKES OVER THE NEXT FEW HOURS...AND THERE IS STILL A POSSIBILITY WE SEE SOME SOUTHWARD DEVELOPMENT INTO NORTHERN LOWER MICHIGAN ALONG THE ADVANCING MOISTURE AXIS. FOR THIS REASON...WILL MAINTAIN LOW CHANCY POPS DOWN THROUGH NORTHERN LOWER MICHIGAN AS WELL...ALTHOUGH IT/S LIKELY MOST OF NRN LOWER MICHIGAN REMAINS DRY AS THIS SYSTEM MOVES ON TO THE EAST. SEVERE WEATHER...AT THIS JUNCTURE (4 AM) JUST DEALING WITH ONE CORE CELL STARTING TO BEAR DOWN ON CHIPPEWA COUNTY. NICE STOUT OUTFLOW WITH THIS STORM WHICH IS TRYING TO BOW OUT JUST A BIT...ALONG WITH IMPRESSIVE STORM TOP (OVER 50K)/ELEVATED CORES. WE MAY YET SEE SOME SEVERE WINDS OR HAIL AS IT MOVES THROUGH (NOTE GRAND MARAIS REPORTED A 52 KNOT GUST AS THE STORM MOVED THROUGH). BUT UNLESS SOMETHING ELSE GETS GOING...OR THIS STORM MAKES A HARD RIGHT TURN SOUTH...THIS MAY BE THE EXTENT OF SEVERE WEATHER WITH THIS PARTICULAR COMPLEX. LATE MORNING THROUGH THIS AFTERNOON...SOME LOW CLOUD COVER BEHIND THE STORM COMPLEX WILL LINGER ACROSS THE REGION INTO EARLY AFTERNOON BEFORE BURNING OFF. BUT...ACTUAL SFC COLD FRONT IS STILL UPSTREAM AND FORECAST TO SLOWLY CROSS THE CWA DURING THE AFTERNOON HOURS...PROVIDING AN OPPORTUNITY FOR THE E/SE PORTION OF NRN LOWER MICHIGAN TO HEAT UP/DESTABILIZE. MODEL DEPICTION OF LOW LEVEL CONVERGENCE WITH THE FRONT NOT ALL THAT IMPRESSIVE. BUT WITH ADDED BOOST FROM ANY MARINE BOUNDARY PRESSING IN OFF LAKE HURON...CHANCES FOR SHOWERS/THUNDERSTORMS OVER THE EASTERN COUNTIES AFTER 2 PM THIS AFTERNOON IS A REASONABLE FORECAST. IN FACT...WITH 40 TO 50 KNOTS OF WESTERLY MID LEVEL FLOW DEVELOPING ACROSS NORTHERN LOWER MICHIGAN THIS AFTERNOON...ANY STORMS THAT DEVELOP WILL POSE A SEVERE WEATHER THREAT PARTICULARLY ALONG ANY MARINE BOUNDARY IN THE EAST. ADAM && .LONG TERM.../ISSUED AT 408 AM/...TONIGHT AND BEYOND SUPPRESSED HEIGHTS AND MID LEVEL FLOW VEERING NORTHWESTERLY WILL BE THE TREND THROUGH THE BALANCE OF THE WEEKEND...COOLING THINGS OFF JUST A TAD TO START THE NEW WEEK. HIGH PRESSURE BUILDING OVERHEAD FOR SUNDAY WILL LEAD TO RAIN-FREE CONDITIONS. THEN...MID LEVEL IMPULSE AND UPPER JET CORE SLIDING THROUGH THE NORTHERN PART OF THE STATE MONDAY MAY BRING SOME SHOWERS INTO THE PICTURE TO START THE WORK WEEK. TONIGHT...WILL STRETCH CHANCY POPS INTO THE EARLY EVENING HOURS (00Z) OVER THE FAR SE COUNTIES...TO COVER ANY STORMS THAT MAY DEVELOP WITH HEATING THIS AFTERNOON. BUT BEYOND THAT...COOLER AND DRIER AIR WILL BEGIN TO FILTER INTO NORTHERN MICHIGAN THROUGH THE COURSE OF THE NIGHT...ALONG WITH DECREASING CLOUDS. SUNDAY AND SUNDAY NIGHT...EXPECTED TO BE NICE AS SFC HIGH PRESSURE SLIDES THROUGH THE REGION PROVIDING A FAIR AMOUNT OF SUNSHINE THROUGH THE DAY...PARTLY CLOUDY CONDITIONS SUNDAY NIGHT. MONDAY...STRONG UPPER JET CORE FORECAST TO DEVELOP ACROSS SRN ONTARIO...ALONG WITH SOME SEMBLANCE OF A WEAK FRONT SLIPPING THROUGH THE STATE. NOT TERRIBLY IMPRESSIVE FROM A MOISTURE STANDPOINT HOWEVER...WITH QUITE A BIT OF DRY AIR IN THE LOWER LAYERS. NONETHELESS...PROBABLY A GOOD IDEA TO KEEP LOW CHANCY POPS IN THE FORECAST MONDAY AND MONDAY NIGHT. BUT FROM MY VANTAGE POINT... THUNDER CHANCES ARE LOOKING PRETTY SLIM. ADAM && .MARINE.../ISSUED AT 408 AM/ COLD FRONT WILL SLIP THROUGH THE REGION TODAY...TURNING WINDS MORE NORTHWESTERLY. MAY GET A LITTLE GUSTY BEHIND THE FRONT ESPECIALLY ACROSS WHITEFISH BAY/SAINT MARYS RIVER AND DOWN INTO NORTHERN LAKE HURON...WHERE STRONGER WINDS ALOFT WILL BE FOUND. BUT THINK OVERALL GUSTS/WAVES WILL REMAIN SHY OF SMALL CRAFT CRITERIA THROUGH TONIGHT. HIGH PRESSURE BUILDS OVERHEAD ON SUNDAY WITH LIGHTER WINDS CONTINUING TO DOMINATE. ADAM && .AVIATION.../ISSUED AT 112 AM/...VALID FOR 06Z TAFS UNCERTAINTY REMAINS REGARDING EVENTUAL COVERAGE OF SHOWERS AND THUNDERSTORMS FOR THE TERMINAL SITES OVERNIGHT...IN ADVANCE OF A COLD FRONT APPROACHING THE REGION. REGIONAL RADARS SHOW STORMS ONGOING ACROSS THE WESTERN U.P. AND LAKE SUPERIOR...AND SUSPECT THESE WILL CONGEAL INTO SOME SORT OF BROKEN LINE THROUGH 2-4 AM...BEFORE MAKING A RUN TOWARD MOST OF THE TERMINAL SITES LATE TONIGHT. GIVEN UNCERTAINTY HOWEVER...WILL SHOW NO RESTRICTIONS TO VISBY OR CEILINGS...THOUGH CERTAINLY COULD BE A BRIEF PERIOD OF IFR WITHIN ANY HEAVIER STORMS. IN THE WAKE OF ANY PRECIPITATION...SHOULD SEE A PERIOD OF MVFR CEILINGS DEVELOP AS MOISTURE POOLS IN ADVANCE OF THE APPROACHING COLD FRONT...WITH CEILINGS LIFTING QUICKLY AROUND MIDDAY AS DRIER AIR BEGINS TO ARRIVE. THE LONE EXCEPTION WILL BE APN...WHERE A LATE DAY SHOWER MAY REDEVELOP AHEAD OF THE FRONT... BEFORE SKIES CLEAR OUT WITH LIGHT WINDS TONIGHT AS HIGH PRESSURE ARRIVES.
