AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
112 PM EDT SAT APR 9 2011

.SYNOPSIS.../ISSUED AT 442 AM/

HIGH PRESSURE WILL MAINTAIN ITS INFLUENCE OVER NORTHERN MICHIGAN
TODAY...BUT LOSE THE BATTLE TONIGHT. A STRONG LOW PRESSURE SYSTEM
WILL CROSS THE PLAINS BRINGING A SIGNIFICANT ONE DAY WARM-UP FOR
PARTS OF NORTHERN MICHIGAN SUNDAY. PERIODS OF SHOWERS AND
THUNDERSTORMS WILL THREATEN THE REGION...TONIGHT THROUGH SUNDAY
NIGHT. HIGH TEMPERATURES WILL BE NEAR RECORD LEVELS...IN MANY
LOCATIONS SUNDAY. THE COLD FRONT ASSOCIATED WITH THIS LOW PRESSURE
SYSTEM...WILL MOVE THROUGH SUNDAY NIGHT...RETURNING TEMPERATURES
BACK TO MORE TYPICAL EARLY APRIL LEVELS NEXT WEEK.

JH

&&

.SHORT TERM.../ISSUED AT 1018 AM/...THIS AFTERNOON

QUIET AND QUITE NICE EARLY SPRING DAY IN THE WORKS...WITH MAIN
CONCERN BEING CLOUD TRENDS AND AFTERNOON HIGHS. MID MORNING QUICK
ANALYSIS PLACES ELONGATED LOW LEVEL RIDGING FROM THE NORTHEAST BACK
THROUGH THE NORTHERN GREAT LAKES...WITH MID LEVEL HEIGHTS ON THE
RISE ACROSS THE REGION AS WELL IN ADVANCE OF DEEP WESTERN CONUS
TROUGHING. PEAK AT FIRST FEW VISIBLE IMAGES OF THE DAY SHOWS
EXPANSIVE PLUME OF LOW CLOUDS (SUB-2KFT) TO THE SOUTH/WEST BENEATH
STOUT LOW LEVEL INVERSION...EXPECTED TO STRENGTHEN WITH TIME THROUGH
THE DAY AS WARM ADVECTION ALOFT CONTINUES TO RAMP UP. HOWEVER...
APPEARS MUCH OF THIS LOW CLOUD COVER WANTS NOTHING TO DO WITH
NORTHERN MICHIGAN THROUGH THE DAY AS TRAJECTORIES WITHIN DEVELOPING
RETURN FLOW REMAIN OUT OF THE SOUTH/SOUTHEAST...FAVORING PLUME OF
LOWER STRATUS STAYING WEST OF THE CWA. ALSO AIDING THINGS IS
INITIALLY VERY DRY AIRMASS (SEE 12Z APX RAOB FEATURING A PWAT OF
JUST A THIRD OF AN INCH)...EXPECTED TO ONLY SLOWLY MOISTEN THROUGH
THE DAY.

WHERE CLOUDS MAY BE A LITTLE MORE SNEAKY IS ACROSS EASTERN UPPER
WHERE SUBTLE PLUME OF MID LEVEL WARM ADVECTION ASCENT IS ONGOING IN
ADVANCE OF WEAK SHORTWAVE RIDING THE TOP OF BUILDING RIDGE AXIS.
THIS HAS MANIFESTED ITSELF IN THE FORM OF A PESKY REDEVELOPING MID
CLOUD DECK...AND SUSPECT THIS MAY HANG AROUND FOR A TIME INTO EARLY
AFTERNOON BEFORE ISENTROPIC DESCENT BEGINS. GIVEN EXPECTED CLOUD
TRENDS AND SLIGHTLY BETTER MIXING THAN YESTERDAY...FORESEE HIGHS A
FEW DEGREES WARMER THAN FRIDAY...AND GOING READINGS IN THE UPPER
50S/LOW 60S LOOK GREAT...OBVIOUSLY MUCH COOLER ALONG THE IMMEDIATE
LAKESHORES WHERE INCOMING LAKE BREEZES WILL EASILY KNOCK READINGS
BACK THROUGH THE 40S (EVEN SOME UPPER 30S RIGHT AT THE SHORE). NOT A
BAD START TO THE WEEKEND...ENJOY!

LAWRENCE

&&

.LONG TERM.../ISSUED AT 442 AM/...TONIGHT AND BEYOND

NO APPRECIABLE DIFFERENCES NOTED AMONG THE NAM/GFS SOLUTIONS THROUGH
DAY 3...AT LEAST IN TERMS OF THEIR RESPECTIVE MASS/THERMAL FIELDS.
OVERALL CONSENSUS SLOWLY MOVES MID-UPPER LEVEL RIDGE AXIS THROUGH
THE GREAT LAKES THROUGHOUT THE WEEKEND BEFORE THE STACKED LOW
PRESSURE SYSTEM NOW OVER THE WEST COAST OPENS AND ADVANCES THROUGH
THE PLAINS AND INTO THE GREAT LAKES BY EARLY MONDAY. THIS ULTIMATELY
DEEPENS AND DRIVES AN AREA OF SFC LOW PRESSURE AND ATTENDING SHARP
COLD FRONT THROUGH THE REGION LATE SUNDAY/EARLY MONDAY AND PRESENTS
THE POSSIBILITIES FOR STRONG STORMS DURING THAT TIME. MORE ON THAT
BELOW...BUT ALWAYS A BIT LEARY WHEN THE MODELS WANT TO QUICKLY OPEN
AND ADVANCE A CLOSED LOW SYSTEM THROUGH THE REGION THAT ORIGINATES
FROM THE SW CONUS. TYPICALLY ITS SLOWER...ALTHOUGH WITH SECONDARY
STRONG PUNCH OF ENERGY DIVING SOUTHWARD OUT OF THE GULF OF ALASKA...
SOLUTIONS ARE MORE BELIEVABLE FOR THIS CASE.

BUT BEFORE THEN...WILL FIRST HAVE TO CONTEND WITH PRECIP
POSSIBILITIES STARTING LATE TONIGHT AND CONTINUING INTO SUNDAY AS
WARM FRONT AND SURGE OF WARM/MOIST AIR DRIVES UP INTO NORTHERN
MICHIGAN. A MESSY FORECAST THROUGH THE WEEKEND WITH LOWER CONFIDENCE
IN PRECIP CHANCES/TIMING DURING ANY ONE FORECAST PERIOD. WHILE IT
DOES APPEAR THAT MOST AREAS WILL SEE PRECIP...NAILING DOWN TIMING TO
A TEE IS SIMPLY NOT POSSIBLE AT THIS JUNCTURE.

TONIGHT THROUGH SUNDAY MORNING...STRONG PULSE OF WARM/MOIST AIR
ADVECTION ALOFT SETS UP ACROSS THE GREAT LAKES STRAIGHT FROM THE
GULF AS LOW PRESSURE SYSTEM DEEPENS IN THE PLAINS IN RESPONSE TO MID
LEVEL SHORT WAVE AND UPPER JET ENERGY EMERGING FROM THE SW CONUS. A
DRY EVENING TO START. THEN MAIN MOIST CONVERGENCE FORCING SLATED TO
ARRIVE AFTER 06Z AND PARTICULARLY TOWARD MORNING AS LOW LEVEL FLOW
STARTS TO RAMP UP DURING THAT TIME. ENVISION A NICE BAND OF PRECIP
DEVELOP AND EXPANDING ACROSS THE WESTERN GREAT LAKES ALONG THE
ADVANCING WARM FRONT ALOFT AND WILL THUS INCREASE POPS SOUTH-NORTH
DURING THE OVERNIGHT HOURS ACCORDINGLY...WITH PRECIP SLOWLY WORKING
THROUGH THE REGION THROUGH SUNDAY MIDDAY.

THUNDER CHANCES...YOU BET...AS STRONG LOW LEVEL WARM/MOIST ADVECTION
PROCEEDS...FORECAST SOUNDINGS BULGE OUT NICELY IN THE LOW LEVELS
LEADING TO OVER 500 JOULES/KG ELEVATED MUCAPE AND NEGATIVE SHOWALTER
INDICES...HIGHEST OF COURSE ACROSS THE SOUTHERN COUNTIES. SO WILL
KEEP ELEVATED TSTMS IN THE FORECAST ALTHOUGH ANY SEVERE THREAT IS
VERY LOW.

SUNDAY AFTERNOON...AFTER INITIAL BATCH OF RAINFALL MOVES OFF SUNDAY
MORNING...SFC WARM FRONT SHOULD HAVE NO PROBLEM LIFTING UP THROUGH
NORTHERN LOWER MICHIGAN AND PERHAPS EVEN EASTERN UPPER MICHIGAN
(WILL SEE) AIDED BY 40+ KNOT 850 MB WINDS PUNCHING INTO THE STATE.
THIS SHOULD PUT NORTHERN LOWER MICHIGAN SQUARELY WITHIN THE WARM
SECTOR AND LEAD TO MAINLY DRY AND POTENTIAL RECORD SETTING WARM
AFTERNOON TEMPERATURES...PROVIDED WE DO NOT GET SOME SHOWERS/THUNDER
TO DEVELOP IN THE INCREASINGLY UNSTABLE AIRMASS. DID RETAIN THE LOW
CHANCE AFTERNOON POPS JUST IN CASE...BUT SUSPECT WE MAY BE ABLE TO
REMOVE THOSE POPS IN LATER FORECASTS.

SUNDAY NIGHT...CERTAINLY THE MOST ACTIVE PART OF THE FORECAST AND
WITH THE USUAL UNCERTAINTIES TO SORT THROUGH. DEEP MID LEVEL TROUGH
AXIS AND ASSOCIATED SFC LOW (TRACKING THROUGH LAKE SUPERIOR) AND
COLD FRONT EXPECTED TO ADVANCE INTO THE WESTERN GREAT LAKES.
RESULTING SYNOPTIC ASCENT/MID-UPPER LEVEL HEIGHT FALLS/LOW LEVEL
CONVERGENCE ALONG THE FRONT THROUGH A FAIRLY UNSTABLE AIRMASS WILL
BE ENOUGH TO DEVELOP ONE OR MORE AREAS OF SHOWERS/STORMS ASSOCIATED
WITH THE PARENT LOW THROUGHOUT THE REGION. PROBLEM IS...THIS SYSTEM
IS STARTING TO HAVE ALL THE EARMARKS OF A NORTHERN LOWER MICHIGAN
SPLIT...WITH A COLD FRONT DRIVEN SQUALL LINE DRIVING THROUGH SRN
LOWER MICHIGAN AND THE OHIO VALLEY...WHILE ADDITIONAL SHOWERS/STORMS
IMPACT THE U.P. ALONG THE MAIN LOW TRACK. IMPOSSIBLE TO KNOW HOW
THIS WILL EVOLVE AT THIS JUNCTURE AND PERHAPS THE VERY STRONG
DYNAMICS WILL BE ENOUGH TO PROVIDE MOST AREAS WITH A HIGH
PROBABILITY OF SHOWERS/STORMS. AS SUCH...HAVE MAINTAINED LIKELY POPS
FOR NOW FOR THIS VERY DYNAMIC SYSTEM.

SEVERE WEATHER THREAT...WARM/HUMID NIGHT BY EARLY SPRING STANDARDS
AND WITH 850 MB WINDS TOPPING 50 KNOTS AND 500 MB WINDS EXCEEDING 90
KNOTS...ANY STORMS WE MANAGE TO GET COULD BE SEVERE...ESPECIALLY IF
WE GET ANY PART OF THE MAIN SQUALL LINE. WILL CERTAINLY CONTINUE TO
HIGHLIGHT THAT THREAT IN THE HWO.

MONDAY...SHARP COLD FRONT EXPECTED TO SWEEP THROUGH THE REGION
MONDAY THAT WILL BRING A QUICK END TO OUR ABOVE AVERAGE
TEMPERATURES...WITH READINGS LIKELY DROPPING THROUGH THE AFTERNOON
HOURS. INITIALLY...MONDAY MORNING MAY START OUT RELATIVELY DECENT IN
THE WAKE OF SUNDAY NIGHTS CONVECTION AND IF SHARP DRY SLOT BLASTS
INTO THE REGION AS FORECAST. BUT PRONOUNCED LOW-MID LEVEL TROUGH
AXES AND ASSOCIATED WRAP AROUND MOISTURE/SHOWERS CURRENTLY EXPECTED
TO WRAP BACK INTO THE AREA MONDAY AFTERNOON AND MONDAY NIGHT. ONCE
AGAIN TEMPTED TO ADD TIMING TO THE FORECAST TO CONVEY A PERIOD OF
DRY WEATHER IN THE MORNING...BUT GIVEN ALL THAT MUST OCCUR BETWEEN
NOW AND THEN...WILL REFRAIN.

NO CHANGES BEYOND MONDAY.

&&

.MARINE.../ISSUED AT 442 AM/

OVERALL LIGHT WINDS ANTICIPATED THROUGH TODAY UNDER THE INFLUENCE OF
SFC HIGH PRESSURE. LAKE BREEZES SHOULD ALSO BECOME DOMINATE THIS
AFTERNOON ALONG ALL NEARSHORE AREAS. WINDS WILL INCREASE FROM THE
SOUTH TONIGHT AND BECOME GUSTY FROM THE SOUTHWEST ON SUNDAY AND WILL
LIKELY PROMPT A ROUND OF SMALL CRAFT HEADLINES FOR MOST IF NOT ALL
NEARSHORE ZONES.

FURTHER AHEAD...COLD FRONT SLIDES THROUGH THE REGION MONDAY. VERY
GUSTY WEST TO NORTHWEST WINDS APPEAR LIKELY ON MONDAY WITH GALE
FORCE WIND GUSTS A POSSIBILITY.

ADAM

&&

.AVIATION.../ISSUED AT 112 PM/...VALID FOR 18Z TAFS

SOMEWHAT TRICKY CEILING/VISIBILITY FORECAST OVER THE NEXT 24
HOURS...AS A WARM FRONT LIFTS NORTHWARD INTO NORTHERN LOWER
MICHIGAN. SOLID VFR CONDITIONS WILL CONTINUE INTO THE FIRST HALF
OF THE NIGHT...BEFORE LOWER CLOUDS LIKELY SPREAD NORTH WITH TIME
AS LOW LEVEL MOISTURE INCREASES RAPIDLY AFTER 06Z. ALL THE
WHILE...EXPECT SEVERAL AREAS OF SHOWERS AND THUNDERSTORMS WILL
DEVELOP UPSTREAM AND PUSH EAST ACROSS THE TAF SITES TOWARD
SUNRISE...MOST LIKELY AFFECTING TVC IN CLOSER PROXIMITY TO THE
WARM FRONT...BUT PROBABLY ALSO SCRAPING BY PLN/APN THROUGH MID
MORNING. WIDESPREAD IFR CONDITIONS SHOULD DEVELOP JUST IN ADVANCE
OF THE BOUNDARY AS MOISTURE POOLS...WITH LOW LEVEL WIND SHEAR ALSO
BEING AN ISSUE GIVEN CRANKING FLOW JUST OFF THE SURFACE...BEFORE
CEILINGS BEGIN TO RAPIDLY MIX OUT FROM SOUTH TO NORTH AS THE WARM
FRONT SURGES NORTH TOWARD THE END OF THE TAF PERIOD.
