AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
105 AM EDT TUE MAY 19 2015

.UPDATE...
ISSUED AT 1102 PM EDT MON MAY 18 2015

JUST SOME MINOR TWEAKS TO THE FORECAST FROM THE EARLIER UPDATE.
TEMPS CONTINUE TO TANK QUITE DRAMATICALLY...DOWN NEARLY 30 DEGREES
HERE AT THE OFFICE SINCE LATE THIS AFTERNOON. HAVE LOWERED
EXPECTED MIN TEMPS A FEW MORE DEGREES FROM EARLY FORECAST.

UPDATE ISSUED AT 841 PM EDT MON MAY 18 2015

SHORT WAVE TROUGH SWINGING THROUGH THE UPPER MIDWEST/WESTERN GREAT
LAKES THIS EVENING AND ABOUT TO BRING A POCKET OF UNSEASONABLY
COOL AIR TO THE REGION (NEARLY -10C AT 800 MB ON KINL 00Z SOUNDING).
ATTENDING SFC LOW PRESSURE IS ROCKETING OFF TO THE EAST...NOW OVER
FAR SRN ONTARIO INTO QUEBEC. TRAILING COLD IS JUST NOW PUSHING
THROUGH NE LOWER MICHIGAN (CAN BE SEEN ON RADAR) AND PASSED
THROUGH THIS OFFICE JUST BEFORE 6 PM KICKING WINDS INTO THE WEST
AND DROPPING TEMPS AROUND 20 DEGREES SINCE.

MEANWHILE...LARGE EXPANSE OF "WRAP AROUND" LOWER CLOUD COVER
STRETCHES FROM WISCONSIN BACK INTO THE DAKOTAS. SOME HEATING
INDUCED SHOWERS OCCURRING AROUND DULUTH INTO NW WISCONSIN. SOME
BETTER ORGANIZED PRECIP/SMALLER SCALE SHORT WAVE MOVING THROUGH
LAKE SUPERIOR. CLOUD COVER WILL BE SPREADING EASTWARD ACROSS THE
CWA THIS EVENING AND OVERNIGHT...IT/S JUST A MATTER OF TIMING.
CURRENT TRENDS SUGGEST MUCH OF NW LOWER MICHIGAN WILL BE PARTLY
CLOUDY TO OVERCAST BY MIDNIGHT WITH CLOUD COVER CONTINUING TO
SPREAD INTO NE LOWER MICHIGAN OVERNIGHT. FAR SE COUNTIES MIGHT BE
SPARED FLAT OUT OVERCAST SKIES BY MORNING BY VIRTUE OF WESTERLY-
NORTHWESTERLY DOWNSLOPE FLOW. BUT EVERYONE ELSE...BECOMING
CLOUDY.

PRECIP-WISE...JUST NOT VERY EXCITED ABOUT THE PROSPECTS. SOME
DEEPER MOISTURE ROTATING THROUGH UPPER MICHIGAN WITH THE SECONDARY
SHORT WAVE MIGHT BRING A LITTLE BIT OF SPRINKLES TO EASTERN UPPER
MICHIGAN TONIGHT. BUT FORECAST SOUNDINGS SUGGEST MORE -DZ THAN
ANYTHING AND FORECAST TEMP PROFILES JUST AREN/T COLD ENOUGH TO
SUPPORT SNOWFLAKE PRODUCTION. WILL SEE WHAT THE 00Z GUIDANCE DATA
HAS IN STORE...BUT WILL PROBABLY END UP REMOVING SNOW WORDING
FROM THE U.P. TONIGHT AND TUESDAY. ACROSS NRN LOWER MICHIGAN...
PERHAPS SOME DRIZZLE IN THE HIGH TERRAIN OVERNIGHT.

&&

.NEAR TERM...(THIS EVENING THROUGH TONIGHT)
ISSUED AT 339 PM EDT MON MAY 18 2015

HIGH IMPACT WEATHER POTENTIAL...TURNING MUCH COOLER.

LOW PRESSURE TO OUR NORTH HAS TAKEN AN ABRUPT JUMP EAST...AND IS NOW
NE OF THE SAULT. THE COLD FRONT HAS ALSO TAKEN ON A MORE COMPLEX
STRUCTURE...WITH A PRE-FRONTAL TROF PUSHING INTO NE LOWER...AND THE
FRONT ITSELF VENTURING ACROSS LAKE MI. SCT -SHRA HAVE DEVELOPED IN
THE CONGESTED CU FIELD IN SE SECTIONS OF THE FORECAST AREA. MOST
OF THESE ARE NOW LOCATED OVER LAKE HURON. SKIES WERE MOSTLY SUNNY
IN NORTHERN LOWER NEAR LAKE MI...AND MUCH OF EASTERN UPPER.
EXTENSIVE POST-FRONTAL CLOUD SHIELD IS BACK IN WI AND WESTERN
UPPER MI...WHERE SURFACE TEMPS HAVE NOT BUDGED ALL DAY LONG.

UPSTREAM CLOUD COVER WILL ACCELERATE EASTWARD TONIGHT...ONCE DIURNAL
HEATING/MIXING DWINDLES. ALL AREAS WILL BECOME OVERCAST DURING THE
LATE EVENING AND OVERNIGHT HOURS. DEEPER MOISTURE IS PRESENT AS YOU
HEAD FURTHER NORTH...AS UPSTREAM RADAR LOOPS MAKE SELF-EVIDENT. THE
MOST WIDESPREAD ACTIVITY WILL STAY NORTH OF UPPER MI. BUT THE UP
WILL BE GRAZED BY SOME SHOWERS ALONG THE SOUTHERN PERIPHERY OF THE
CYCLONIC SWIRL NOW NEARING ISLE ROYALE. WILL THUS MAINTAIN A CHANCE
OF SHOWERS IN EASTERN UPPER...ESPECIALLY CENTRAL/NORTHERN CHIPPEWA
CO. THIS WILL BE ALL LIQUID THRU THE EARLY OVERNIGHT HOURS...BUT
COULD MIX WITH WET SNOWFLAKES TOWARD DAYBREAK AS SURFACE TEMPS DIP
TOWARD THE UPPER 30S. FOR NORTHERN LOWER MI...THERE IS NO PRECIP
EVIDENT UPSTREAM...BUT CIGS ARE QUITE LOW IN WESTERN WI (ALONG WITH
SOME MINIMAL VSBY RESTRICTIONS...2-5SM). WOULD NOT BE SURPRISED TO
SQUEEZE OUT SOME SPRINKLES OR DRIZZLE LATE TONIGHT AS THIS AIRMASS
ASCENDS INTO THE HIGHER TERRAIN OF NORTHERN LOWER. HAVE THUS ADDED
SOME LATE-NIGHT SPRINKLES OVER THE HIGHER ELEVATIONS.

TEMPS WILL PLUNGE RAPIDLY BEGINNING EARLY THIS EVENING. BY 8
AM...EXPECT READINGS IN THE UPPER 30S TO NEAR 40F IN MOST OF
NORTHERN MI. HOWEVER...NE LOWER MI FROM APN SOUTHWARD WILL HANG ONTO
THE MID TO EVEN UPPER 40S. STILL...IT/S A RUDE AWAKENING COMPARED
TO WHAT WE/VE SEEN THE LAST 48 HOURS.

&&

.SHORT TERM...(TUESDAY THROUGH THURSDAY)
ISSUED AT 339 PM EDT MON MAY 18 2015

HIGH IMPACT WEATHER POTENTIAL: WIDESPREAD FROST/FREEZE POTENTIAL
TUESDAY NIGHT. POTENTIAL FOR ADDITIONAL FROST WEDNESDAY NIGHT.

PATTERN SYNOPSIS/ANTICIPATED EVOLUTION: BIG CHANGES A'COMING...WITH
THE DEVELOPMENT OF DEEP NORTHWEST FLOW USHERING IN ONE UNSEASONABLY
CHILLY AIRMASS TO START THE SHORT TERM PERIOD. THEREAFTER...PATTERN
REMAINS AN AMPLIFIED ONE...WITH NORTHERN MICHIGAN REMAINING SQUARELY
UNDER THE INFLUENCE OF COOL NORTHWEST FLOW ON BACKSIDE OF DEEP
EASTERN CANADA CENTERED TROUGHING. NOT AN EXTREMELY ACTIVE
PATTERN...WITH ANY GULF OF MEXICO MOISTURE LOCKED UP WELL TO OUR
SOUTH...WITH JUST SOME LINGERING MOISTURE FROM INITIAL DEPARTING
SYSTEM BRINGING THE POTENTIAL FOR A FEW SHOWERS TUESDAY.

PRIMARY FORECAST CONCERNS/CHALLENGES: PRIMARY FOCUS NO DOUBT
CENTERED ON OVERNIGHT TEMPERATURE TRENDS...ESPECIALLY TUESDAY NIGHT.

DETAILS: NOT PLEASANT! GUSTY NORTHWEST WINDS DO THEIR JOB AS STRONG
HIGH PRESSURE DIVES INTO THE NORTHERN PLAINS TUESDAY. ATTENDANT CAA
IS IMPRESSIVE...WITH H8 TEMPERATURES DROPPING SEVERAL DEGREES BELOW
ZERO THROUGH THE DAY. EXPECT SURFACE TEMPERATURES TO ESSENTIALLY GO
NOWHERE (AND THAT...BY THE WAY...IS AWFULLY HARD TO DO IN THE MIDDLE
OF MAY!)...WITH READINGS LARGELY STUCK IN THE 40S. ADD IN THOSE
WINDS...AND ITS GOING FEEL EVEN SEVERAL DEGREES COLDER. AS FOR
PRECIPITATION POTENTIAL....MOISTURE PLUME TO OUR NORTHWEST ADVANCES
INTO THE AREA...THINNING FROM ABOVE AS IT DOES SO. SOUNDINGS
CONCUR...SHOWING A SHARP LOSS OF MOISTURE WELL SHORT OF -10C. GOTTA
BELIEVE SPRINKLES AT BEST...FOCUSED ACROSS EASTERN UPPER AND PERHAPS
INTO THE HIGHER TERRAIN OF NORTHERN LOWER. OTHERWISE...PLENTY OF
STCU AROUND...LEADING TO A MOSTLY CLOUDY DAY.

ABOVE SETS THE STAGE FOR A VERY COLD TUESDAY NIGHT. JUST HOW COLD
WILL BE TIED TO CLEARING AND WIND TRENDS...ALTHOUGH SIMPLE MAGNITUDE
OF COOLING ASSOCIATED WITH OVERHEAD AIRMASS WILL MAKE IT PLENTY COLD
ENOUGH. AS FOR SKIES...MOISTURE CROSS SECTIONS/SOUNDINGS SUGGEST
SKIES WILL CLEAR THROUGH THE OVERNIGHT. WINDS A TOUGHER
CALL...ALTHOUGH 1000MB GEOSTROPHIC WIND SPEEDS FALLING UNDER 10
KNOTS FULLY SUPPORTS NEAR OR FULL DECOUPLING. GOTTA BELIEVE ABOVE
OFFERS A SEVERAL HOUR OPPORTUNITY FOR READINGS TO REALLY TANK DURING
THE EARLY MORNING HOURS...ALLOWING THE TYPICAL COLDER INTERIOR
LOCATIONS TO MAKE A RUN AT THE UPPER (MIDDLE?) 20S. OF
COURSE...READINGS WILL BE AT LEAST A FEW DEGREES MILDER NEAR THE
COAST. LITTLE DOUBT FROST/FREEZE HEADLINES WILL BE NEEDED FOR
NORTHERN LOWER (THAT SEASON DOES NOT START UNTIL MAY 25TH FOR
EASTERN UPPER). A TOUCH TOO EARLY TO DO SO JUST YET...BUT WILL
CONTINUE TO HIT THIS THREAT HARD IN OUR LATEST WEATHER GRAPHIC AND
HAZARDOUS WEATHER PRODUCTS.

HIGH PRESSURE AND DRY AIR DOMINATES THEREAFTER...EXTENDING THE DRY
WEATHER THROUGH THURSDAY. LOW PRESSURE ADVANCING WELL TO OUR SOUTH
LATER WEDNESDAY MAY SPREAD SOME HIGH CLOUDS OVERHEAD...AND WILL NEED
TO WATCH A WEAK WAVE DIVING ON BACKSIDE OF EAST CANADA TROUGHING
THURSDAY. ATMOSPHERE APPEARS JUST TOO DRY TO KICK OFF ANY PRECIP
WITH THIS LATTER FEATURE...BUT SOMETHING TO WATCH. AIRMASS WILL
MODIFY AS OVERHEAD THERMAL TROUGHING RELAXES AND PUSHES
EAST...ALLOWING HIGHS TO SLOWLY RECOVER. STILL LOOKING CHILLY
WEDNESDAY NIGHT...ALTHOUGH LIGHT WINDS AND MODIFIED AIRMASS WILL
LIKELY KEEP READINGS SEVERAL DEGREES WARMER THAN THOSE OBSERVED
TUESDAY NIGHT. STILL...LOWS BACK DOWN INTO THE MIDDLE 30S FOR
INTERIOR REGIONS MAY ONCE AGAIN REQUIRE THE NEED FOR SOME FUTURE
FROST HEADLINES.

&&

.LONG TERM...(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 339 PM EDT MON MAY 18 2015

QUIET START TO THE EXTENDED PERIOD WITH HIGH PRESSURE OVER THE
REGION. COULD BE SOME CONTINUED FROST CONCERNS THURSDAY AND FRIDAY
NIGHT WITH THE N/NW FLOW AND CLEAR SKIES...BUT THE TEMPS ARE
BORDERLINE AND IT IS STILL A WAYS OUT. WORTH KEEPING AN EYE ON AS WE
DRAW CLOSER. TEMPS WILL START OUT A BIT BELOW NORMAL FRIDAY...BUT
REBOUND FOR A NICE WEEKEND WITH TEMPS RANGING THROUGH THE 60S
SATURDAY AND SUNDAY BEFORE DIPPING A BIT AGAIN ON MONDAY AS THE NEXT
LOW PRESSURE SYSTEM MOVES THROUGH THE REGION.  THAT LOW PRESSURE
SYSTEM WILL ALSO BRING THE NEXT CHANCE OF RAIN AS THE ATTENDANT WARM
FRONT TRANSITS MICHIGAN SOMETIME SUNDAY INTO THE BEGINNING OF NEXT
WORK WEEK. PROGGED INSTABILITY OVER NORTHERN MICHIGAN IS NOT OVERLY
IMPRESSIVE AT THIS TIME...BUT THERE COULD BE SOME ISOLATED THUNDER
WITH THIS SYSTEM.  THE H5 TROUGH THAT WILL BE LIFTING THIS LOW OUT
OF THE PLAINS IS STILL OFF IN THE PACIFIC...AND AS SUCH THE TRACK
AND SPEED OF THE LOW HAS A LOT OF UNCERTAINTY. WILL KEEP WITH
INHERITED SLIGHT CHANCE FOR THUNDER SUNDAY AND ADD FOR MONDAY AS
WELL...BUT THIS COULD EASILY CHANGE GIVEN TRACK UNCERTAINTIES AND
ALREADY MARGINAL INSTABILITIES.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY NIGHT)
ISSUED AT 105 AM EDT TUE MAY 19 2015

MAINLY MVFR CIGS ARE EXPECTED FOR ALL NRN LWR MICHIGAN TAF SITES
OVERNIGHT...TODAY AND INTO THIS EVENING AS AMPLE LOW LEVEL
MOISTURE/CLOUDS WRAP INTO THE GREAT LAKES REGION ACCOMPANIED BY
STRONG CAA IN THE WAKE OF DEPARTING LOW PRESSURE. SOME PATCHY
DRIZZLE OR SPRINKLES ARE POSSIBLE ACROSS THE HIGHER TERRAIN OF NRN
LWR MICHIGAN. NW WINDS WILL STRENGTHEN TODAY...WITH GUSTS OF 25
KTS EXPECTED.

LULL...MARINE CONDITIONS WILL GET GUSTIER AND CHOPPIER LATE

LATE TONIGHT INTO TUESDAY AFTERNOON. ADDITIONAL ADVISORIES WILL
LIKELY BE NEEDED ON OTHER WATERS ON TUESDAY.
