AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
1146 PM EDT MON JUN 20 2011

.SYNOPSIS.../ISSUED AT 433 PM/

THE WEATHER OVER THE GREAT LAKES...WILL STRUGGLE BETWEEN CANADIAN
HIGH PRESSURE...WANTING TO EXERT ITS INFLUENCE...AND A SERIES OF
WEAK UPPER LEVEL DISTURBANCES THAT WANT TO BRING SPOTTY SHOWERS TO
THE REGION. THIS WILL BE THE CASE UNTIL A MORE ORGANIZED LOW
PRESSURE SYSTEM MOVES THROUGH WEDNESDAY. THE RESULT WILL BE PARTLY
TO MOSTLY CLOUDY SKIES...WITH CHANCES FOR SHOWERS...AND POSSIBLY
SOME THUNDERSTORM THE NEXT FEW DAYS.

JH

&&

.SHORT TERM.../ISSUED AT 1020 PM/...TONIGHT

VERY MOIST (PWAT VALUES OVER 1.2 INCHES) LOW-MID LEVEL AIR
CONTINUES TO ADVANCE INTO THE REGION...KICKED ALONG BY ANOTHER
MID LEVEL IMPULSE MOVING NORTHEASTWARD THROUGH UPPER MICHIGAN/LAKE
SUPERIOR (PER WATER VAPOR IMAGERY). HAVE SEEN POCKETS OF SHOWERS/A
LITTLE BIT OF THUNDER WORK THROUGH THE CWA OVER THE LAST SEVERAL
HOURS...AND SHOWERS/ISOLATED THUNDER CONTINUE TO BUBBLE UP EVEN AT
THIS LATER HOUR...INDICATIVE OF THE MOIST INCOMING AIRMASS.

REST OF TONIGHT...DESPITE BOUNDARY LAYER COOLING...THINK WE WILL
CONTINUE TO SEE SHOWERS/ISOLATED THUNDER POP UP THROUGH THE
BALANCE OF THE NIGHT...PARTICULARLY OVER THE SW PORTION OF THE CWA
WHERE DEWPOINTS ARE RUNNING HIGH. MAY ALSO SEE ANOTHER BATCH OF
REDEVELOPMENT TO OUR SOUTH ULTIMATELY PRESSING INTO THE S/SW
COUNTIES TOWARD MORNING...AS GUIDANCE DEPICTS ANOTHER BIG SURGE OF
LOW-MID LEVEL MOISTURE AHEAD OF THE ADVANCING WARM FRONT. HAVE
ADJUSTED/TWEAKED POPS TO THIS THINKING.

FOG...SHOULD GET RATHER THICK FOR AREAS AROUND TVC/MBL/CAD...GIVEN
THE GOOD AMOUNT OF RAINFALL EARLIER IN THE DAY/LIGHT WINDS AND SFC
DEWPOINTS IN THE MID TO UPPER 60S. LESS FOG HEADING TO THE NORTH
AND EAST.

ADAM

&&

.LONG TERM.../ISSUED AT 433 PM/...TUESDAY AND BEYOND

A WARM FRONT WILL GRADUALLY LIFT INTO LOWER MICHIGAN THROUGH
WEDNESDAY...AHEAD OF SLOW MOVING LOW PRESSURE WHICH WILL PASS
OVERHEAD THURSDAY. THIS WILL BRING A CLOUDY AND WET PERIOD OF
WEATHER THROUGH THE WORK WEEK. HIGHER PRESSURE WILL THEN GRADUALLY
BUILD INTO THE REGION...ALLOWING THE SUN TO BECOME MORE COMMON THAN
NOT.

TUESDAY THROUGH THURSDAY...LOW PRESSURE WILL START OUT OVER EASTERN
NEBRASKA TUESDAY MORNING...AND TAKE IT'S TIME TRACKING EASTWARD
ALONG A WARM/STATIONARY FRONT. THIS FRONT IS EXPECTED TO REACH THE
SRN CWA WEDNESDAY...ALTHOUGH THE NORTHWARD PUSH OF THE FRONTAL ZONE
WILL BE DRIVEN AND INFLUENCED BY ROUNDS OF MAINLY NIGHT TIME SHOWERS
AND STORMS THAT WILL BE FIRING OFF IN IT'S VICINITY. SOUTHERLY WINDS
HAVE ALREADY BROUGHT DEEP MOISTURE UP INTO THE SRN GREAT LAKES...AND
THIS WARM/MOIST FEED WILL CONTINUE THROUGH WEDNESDAY...WHEN THE LOW
PRESSURE OCCLUDES...ALLOWING A COLD FRONT TO PASS THROUGH THE
REGION. PWATS THROUGH WEDNESDAY WILL INCREASE TO 1.75" TO ALMOST
2.00"...SO ANOMALOUSLY HIGH WATER CONTENT. THE EAST WEST FRONTAL
ZONE AND A STEADY SOUTH FEED OF HIGH THETA-E AIR OVER THE FRONT WILL
WILL BE PRONE FOR POTENTIALLY HEAVY RAINFALL THROUGH THIS TIME.
INDIVIDUAL STORMS WILL ALSO BE ABLE TO DELIVER LOCALLY HEAVY
RAINFALL. FROM AN INSTABILITY STANDPOINT...LAPSE RATES ARE NOT ALL
THAT FANTASTIC...REMAINING BELOW 6C/KM. FROM A CAPE
PERSPECTIVE...THIS WILL BE DEPENDENT UPON POTENTIAL CLEARING IN THE
DAYTIME...TO WHICH 1200J/KG OF SBCAPE WILL BE POSSIBLE WHILE
ELEVATED CAPES AT NIGHT LOOKING TO BE BELOW 800J/KG. WIND FIELDS ARE
NOT THAT INCREDIBLE EITHER...THE LLJ NEVER GETS TO 25-30KTS WHILE
0-6KM BULK SHEAR VALUES REMAIN BELOW 40KTS OUTSIDE OF TUESDAY
AFTERNOON WITH THE PASSAGE OF A MODEST MID LEVEL JET STREAK. THIS
SPELLS MORE OF A HEAVY RAINFALL/POTENTIAL FLOODING PERIOD OF
WEATHER...ESPECIALLY IF RAINFALL IS ABLE TO TRACK OVER THE SAME
AREAS THROUGH WEDNESDAY. THE QUITE CLOUDY AND DAMP CONDITIONS
RESULTED IN LOWERING HIGH TEMPERATURES TO MAINLY THE MIDDLE 60S TO
MIDDLE 70S. THAT SAID...STRONG JUNE SUN...IF IT POPS OUT AT TIMES IN
THE AFTERNOON...WILL CERTAINLY ALLOW FOR WARMER/MUGGIER WEATHER. ON
THURSDAY...THE LOW ARRIVES OVERHEAD WITH SHOWERS LIKELY DOTTING THE
REGION...RUMBLES OF THUNDER ACROSS NE LOWER...BUT STILL NOT MUCH IN
THE WAY OF INSTABILITY OR FAVORABLE WIND FIELDS. BUT HEY...IT'LL
STAY CLOUDY...AGAIN.

FRIDAY...THE LOW PRESSURE STARTS TO LIFT OUT OF THE REGION...BUT
DEEP MOISTURE REMAINS OVER THE NORTH WOODS...ALONG WITH SOME COOLER
AIR. GOTTA BELIEVE THERE WILL STILL BE AT LEAST SOME LIGHT SHOWERS
AROUND...ESPECIALLY WITH THE PASSAGE OF A SFC TROUGH BEHIND THE
DEPARTING LOW. POPS FOR THIS PERIOD MAY HAVE TO BE INCREASED WITH
TIME. HIGH TEMPERATURES IN THE LOW 60S TO AROUND 70.

SATURDAY THROUGH MONDAY...FINALLY THE WEATHER STARTS LOOKING UP. LOW
PRESSURE CONTINUES TO LIFT OUT OF THE GREAT LAKES...FAR ENOUGH AWAY
FOR THE DEEP MOISTURE TO GET OUT OF HERE. PROBABLY SEE A CLOUDY
START TO THE DAY...BUT THE SUNSHINE WILL BE INCREASING AS WE HEAD
THROUGH THE DAY. ALTHOUGH SOME LEVEL OF UNCERTAINTY ALWAYS EXISTS
OUT THIS FAR IN THE FORECAST...HIGH PRESSURE SETTLES IN BY SATURDAY
NIGHT...AND THE AIR MASS DRIES. LATEST ECMWF REMAINS QUICKER WITH
THE PATTERN...AND SUGGESTS WE MAY HAVE TO DODGE A SHORTWAVE SUNDAY
AND POSSIBLE SHOWERS/STORMS. TEMPS SHOULD BE IN THE MIDDLE AND UPPER
70S. MUCH BETTER THAN WHAT WE HAVE IN STORE FOR THIS WORK WEEK.

SMD

&&

.MARINE.../ISSUED AT 433 PM/

A WARM FRONT WILL GRADUALLY LIFT INTO LOWER MICHIGAN THROUGH
WEDNESDAY...AHEAD OF SLOW MOVING LOW PRESSURE WHICH WILL PASS
OVERHEAD THURSDAY. THIS WILL BRING A CLOUDY AND WET PERIOD OF
WEATHER THROUGH THE WORK WEEK. EASTERLY WINDS WILL GRADUALLY
INCREASE AS THE LOW PRESSURE NEARS...PARTICULARLY TUESDAY NIGHT
AND WEDNESDAY WITH THE STRONGEST WINDS LIKELY FUNNELING THROUGH THE
STRAITS REGION. WINDS OVER THE SRN NEARSHORES WILL LIKELY TURN
SOUTHERLY WEDNESDAY...WITH WEAKENING SOUTH WINDS DEVELOPING MOST ALL
NEARSHORES BY LATE THURSDAY AFTERNOON. CONDITIONS OVER THE LAKES IN
THE INCREASINGLY WARM AND HUMID AIR MASS WILL BECOME MORE AND MORE
STABLE...WHICH WILL OFFSET THE 25-35KT 950MB WINDS. SMALL CRAFT
ADVISORIES WILL LIKELY BE NEEDED...MAINLY FROM THE STRAITS
NORTHWARD.

SMD

&&

.AVIATION.../ISSUED AT 1146 PM/...VALID FOR 06Z TAFS

ACTIVE WEATHER ANTICIPATED ACROSS NORTHERN LOWER MICHIGAN OVER THE
NEXT 24 HOURS (AND BEYOND). STACKED LOW PRESSURE IN THE CENTRAL
PLAINS HELPING TO PUMP MOIST AIR NORTHWARD INTO THE GREAT LAKES.
ISOLATED-SCATTERED SHOWERS AND SOME THUNDER WILL CONTINUE TO BUBBLE
UP OVER PORTIONS OF NORTHERN LOWER MICHIGAN THROUGH THE OVERNIGHT
HOURS...PARTICULARLY AROUND THE TVC TERMINAL SITE. PLN/APN WILL
LIKELY REMAIN VFR THROUGH THE NIGHT...WHERE SFC DEWPOINTS ARE LOWER.
TVC HOWEVER...MAY END UP WITH A PERIOD OF MVFR CONDITIONS (CIGS AND
VSBYS) OVERNIGHT INTO TUESDAY DUE TO HIGHER SFC DEWPOINTS IN THAT
AREA.

ON TUESDAY...BIGGEST SURGE OF MOIST AIR EXPECTED TO ADVANCE THROUGH
LOWER MICHIGAN THROUGH THE DAY...AS THE STACKED LOW IN THE PLAINS
PROGRESSES INTO THE WESTERN GREAT LAKES DRIVING A WARM FRONT INTO
LOWER MICHIGAN. FORCING ALONG THE FRONT/DAYTIME HEATING WILL COMBINE
TO DEVELOP ANOTHER ROUND OF SHOWERS/STRONG STORMS THAT WILL LIFT
INTO NORTHERN MICHIGAN THROUGH THE AFTERNOON/EVENING. FRONT MAY
STALL OUT ACROSS LOWER MICHIGAN BY TUESDAY NIGHT...A GOOD SET-UP FOR
PROLONGED HEAVY RAINFALL TO PERSIST ACROSS THE REGION INTO
WEDNESDAY. MVFR CONDITIONS BECOME PREVALENT TUESDAY AFTERNOON...
FOLLOWED BY LIKELY IFR CONDITIONS TUESDAY NIGHT.
