AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
ISSUED BY NATIONAL WEATHER SERVICE MARQUETTE MI
400 PM EDT WED APR 25 2012

.SYNOPSIS...
ISSUED AT 400 PM EDT WED APR 25 2012

LOW PRESSURE WILL SLIDE TO OUR SOUTH TO THE OHIO VALLEY NIGHT. THIS
SYSTEM WILL BRING OUR ONLY REAL SHOT AT RAINFALL OVER THE NEXT 5 TO
7 DAYS FOR LATE THIS EVENING INTO TONIGHT...WITH HIGH PRESSURE AND
DRY BUT QUITE COOL WEATHER RETURNING THROUGH EARLY NEXT WEEK.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 400 PM EDT WED APR 25 2012

THE CWA IS CURRENTLY UNDER AN UPPER SHORTWAVE RIDGE IN GENERALLY NW
FLOW BETWEEN A 500MB TROUGH FROM HUDSON BAY TO JUST OFF THE E
COAST...AND A 500MB RIDGE FROM MEXICO INTO NWRN CANADA. THERE IS
ALSO A SHORTWAVE TROUGH OVER NRN ONTARIO THAT IS ROTATING AROUND A
500MB LOW OVER HUDSON BAY. AT THE SFC...HIGH PRESSURE IS CENTERED
OVER THE LOWER GREAT LAKES...WITH A 1000MB LOW OVER IA/SRN MN. RAIN
HAS BEEN MOVING THROUGH THE UPPER RIDGE IN AN AREA OF WAA AHEAD OF
THE SFC LOW. SO FAR...PRECIP HAS BEEN OBSERVED ON RADAR MOVING INTO
THE SWRN PART OF THE CWA...BUT IT IS UNLIKELY THAT ANY RAIN IS
MAKING IT TO THE GROUND. SFC DEW PT DEPRESSIONS ARE ON THE ORDER OF
25-30 DEGREES...WITH VERY DRY CONDITIONS OBSERVED BY THE APX
SOUNDING BELOW 550MB.

THE SFC LOW WILL MOVE TO OH BY 12Z THU...AS THE NRN ONTARIO
SHORTWAVE MOVES OVER THE U.P. OF MI. THE MAIN ENERGY WITH THIS
SHORTWAVE WILL BE OVER THE NRN PORTIONS OF THE CWA AS IT PIVOTS OVER
LAKE ONTARIO BY 18Z THU. 850MB TEMPS WILL BE ABOVE 0C OVER MOST OF
THE CWA THROUGH 00Z THU...AND WILL BEGIN TO QUICKLY FALL FROM N TO S
AROUND 12Z THU AS THE SHORTWAVE MOVES IN. BY 18Z THU...850MB TEMPS
OVER THE ENTIRE CWA WILL BE NEAR OR BELOW -5C...WITH TEMPS DOWN TO
-10C OVER NRN PORTIONS OF THE CWA. INCREASED LOW LEVEL MOISTURE WILL
SKIRT OUR FAR SWRN COUNTIES THIS EVENING...AND WILL BEGIN TO MOVE
INTO THE REST OF THE WRN CWA AROUND 00Z THU. LOW LEVEL MOISTURE WILL
COVER THE ENTIRE CWA BY 06Z THU BEFORE DRY LOW LEVEL AIR MOVES OVER
AGAIN THU. ALL THIS SAID...MAIN AREAS OF PRECIP THIS EVENING INTO
THU MORNING WILL BE OVER THE FAR SWRN CWA AND OVER FAR ERN UPPER MI.
PRECIP DOWNWIND OF THE GREAT LAKES (ERN UPPER MI AND FAR NWRN LOWER
MI) WILL BE AIDED BY SOME LAKE ENHANCEMENT THU MORNING AS WELL AS
UPSLOPE FLOW. COLD AIR WILL MAKE FOR A MIX OF RAIN AND SNOW...MAINLY
N.

THU WILL BE CONSIDERABLY COOLER WITH HIGHS MAINLY IN THE
40S...EXCEPT SOME HIGHS IN THE LOW 50S OVER THE SRN AND SERN CWA. IT
WILL ALSO BE BREEZY...WITH GUSTS TO AROUND 30MPH THROUGH MUCH OF THE
DAY.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 400 PM EDT WED APR 25 2012

THU NIGHT INTO FRI...HIGH PRES FROM NRN MANITOBA WILL BUILD INTO THE
GREAT LAKES BRINGING COLDER AND VERY DRY AIR INTO THE REGION. DESPITE
LINGERING MIXING WITH NNW WINDS OVERNIGHT...EXPECT TEMPS TO DROP
TOWARD THE LOWER END OF GUIDANCE WITH MINS INTO THE LOWER 20S INLAND.
PLENTY OF SUNSHINE FRIDAY WITH MIXING TO AROUND 825 MB WILL SUPPORT
TEMPS INTO THE MID AND UPPER 40S. WITH THE EXTREMELY DRY AIRMASS
MOVING IN...PWAT VALUES TO AROUND 0.10 INCH...DEWPOINTS SHOULD ALSO
FALL AOB GUIDANCE VALUES (5F TO 10F INLAND). LOW RH VALUES TO 15 TO
20 PCT AND GUSTY NNW OF 15 TO 20 MPH WILL LEAD TO ELEVATED WILDFIRE
RISK.

FRI NIGHT AND SATURDAY...WITH THE BLOCKING PATTERN IN PLACE OVER
CANADA...THE PLAINS SHORTWAVE WILL SLIDE THROUGH NRN IL TOWARD THE
ERN LAKES. THIS WILL LEAVE HIGH PRES IN CONTROL WITH DRY WEATHER
OVER THE CWA. COOL CONDITIONS WITH VERY LOW RH WILL ALSO PREVAIL BUT
NE WINDS WILL NOT BE AS STRONG.

SUNDAY THROUGH WEDNESDAY...MODELS SUGGEST THAT THE CNTRL CANADA
RIDGE WILL BREAK DOWN...ALLOWING A TRANSITION TOWARD A MORE ZONAL
PATTERN. EXPECT DRY WEATHER TO PERSIST THROUGH MONDAY AS THE MID
LEVEL AND SFC RIDGE SLIDE SLOWLY TO THE EAST. THERE IS GREATER
UNCERTAINTY FROM TUE INTO WED WITH EXPECTED DIFFERENCES IN
TIMING/POSITION OF SHORTWAVES EMERGING FROM THE PLAINS.
SO...FOLLOWED MDLS CONSENSUS WITH INCREASING PCPN CHANCES
FROM TUE INTO WED AS GREATER MOISTURE MOVES INTO THE REGION. A
WARMING TREND WILL ALSO PUSH TEMPS AOA SEASONAL AVERAGES AS THE
COLDEST AIR MOVES TO THE EAST AND SRLY FLOW/WAA TAKE OVER BY TUE.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 129 PM EDT WED APR 25 2012

CLOUDS WILL GRADUALLY THICKEN AND LOWER THIS EVENING INTO TONIGHT IN
ADVANCE OF AN AREA OF SHRA THAT WILL MOVE EAST ACROSS THE AREA LATE
THIS EVENING/OVERNIGHT. CONDITIONS ARE EXPECTED TO STAY VFR THRU
MOST OF THIS. HOWEVER LOW LEVEL MOISTURE WILL INCREASE IN THE WAKE
OF THIS SYSTEM...SO CIGS WILL CONTINUE TO LOWER AFTER PRECIP
DIMINISHES...AND ALL SITES WILL SEE MVFR CIGS OVERNIGHT. DRY AIR
MOVES IN ON THURSDAY MORNING...BRINGING A RETURN TO VFR CONDITIONS.

&&

.MARINE...
ISSUED AT 400 PM EDT WED APR 25 2012

A LOW PRESSURE SYSTEM WILL SLIDE THROUGH INDIANA AND OHIO BORDER
LATE TONIGHT...BRINGING A BRIEF ROUND OF SHOWERS TO THE WATERS...BUT
ALSO USHER IN ANOTHER ROUND OF GUSTY NORTHWEST WINDS INTO THURSDAY
AS MUCH COLDER AIR ARRIVES. WITH DEVELOPING OVERLAKE INSTABILITY AND
30 KNOTS AVAILABLE TO MIX DOWN...SHOULD BE LOOKING AT SMALL CRAFT
ADVISORY CONDITIONS IN JUST ABOUT ALL NEARSHORE WATERS INTO THURSDAY
MORNING INTO THURSDAY EVENING. THEREAFTER...HIGH PRESSURE IS
EXPECTED TO SLOWLY BUILD SOUTH FROM HUDSON BAY THROUGH THE
WEEKEND...PROVIDING AN EXTENDED PERIOD OF MAINLY LIGHT NORTH TO
NORTHEAST WINDS AND LOW WAVES.

&&

.APX WATCHES/WARNINGS/ADVISORIES...
