AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
357 PM EDT WED JUL 31 2013

.SYNOPSIS...
ISSUED AT 355 PM EDT WED JUL 31 2013

A WEAK COLD FRONT WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS
TO NORTHERN MICHIGAN TONIGHT...WITH THE BEST CHANCES FOR EASTERN
UPPER AND NORTHWEST LOWER. A WEAK DISTURBANCE WILL BRING LOW CHANCES
OF SHOWERS TO NORTHEAST LOWER AND THE EASTERN U.P. FOR
THURSDAY...WITH A SLIGHTLY BETTER CHANCE FOR SHOWERS AND
THUNDERSTORMS FOR ALL OF NORTHERN MICHIGAN AGAIN ON FRIDAY...AS
ANOTHER WEAK COLD FRONT MOVES THROUGH THE AREA. HIGH PRESSURE WILL
BRING FAIR WEATHER FOR THIS WEEKEND.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 355 PM EDT WED JUL 31 2013

FAST FLOW PATTERN CONTINUES ACROSS THE NORTHERN LAKES THIS
AFTERNOON...WITH LEAD SHORTWAVE TROUGH DAMPENING OUT AND MOVING OFF
TO THE EAST...WITH SECONDARY STRONGER SHORTWAVE AND ATTENDANT COLD
FRONT CUTTING INTO THE NORTHWEST LAKES. TOOK A WHILE...BUT
CONVECTION IS STARTING TO FIRE WITH THE LATTER FEATURES...MOST
NOTABLY ACROSS CENTRAL/EASTERN UPPER MICHIGAN WHERE A BROKEN LINE OF
THUNDERSTORMS HAS DEVELOPED IN THE LAST FEW HOURS. NOT MUCH TAKING
PLACE SOUTH OF THE BIG BRIDGE...WITH CLOUD COVER AND LACK OF
DYNAMICS IN WAKE OF FIRST WAVE PREVENTING ANY SHOWER/STORM
DEVELOPMENT. FORECAST CONCERNS CENTER ON SHOWER/STORM POTENTIAL THIS
EVENING...WITH ADDITIONAL LIGHT SHOWER CHANCES NEEDING ADDRESSING
FOR THURSDAY.

UPSTREAM COLD FRONT AND MID LEVEL SUPPORT EXPECTED TO CROSS NORTHERN
MICHIGAN THIS EVENING. JUST ENOUGH FORCING/LOW LEVEL CONVERGENCE TO
CONTINUE TO SUPPORT SHOWER AND STORM DEVELOPMENT ALONG THESE
FEATURES...AND WOULD EXPECT UPSTREAM ACTIVITY TO CONTINUE TO SLOWLY
CONGEAL THIS AFTERNOON. LACK OF PRE-FRONTAL DESTABILIZATION SHOULD
KEEP BOTH COVERAGE AND INTENSITY IN CHECK...AND WILL SIMPLY SPREAD A
BROKEN LINE OF SHOWERS/EMBEDDED STORMS FROM NORTHWEST TO SOUTHEAST
ACROSS THE REGION TONIGHT. ORGANIZED SEVERE WEATHER DEFINITELY NOT
EXPECTED...BUT SUPPOSE AN ISOLATED STRONGER STORM IS POSSIBLE
THROUGH THE REMAINDER OF THIS AFTERNOON...ESPECIALLY ACROSS EASTERN
UPPER MICHIGAN. SHOWER THREAT EXPECTED TO END DURING THE EARLY
MORNING HOURS. POST-FRONTAL DRYING NOT OVERLY AGGRESSIVE...AND WITH
EXPECTED RAINS...FEEL PATCHY/AREAS OF FOG A GOOD BET DURING THE
EARLY MORNING HOURS.

THURSDAY EXPECTED TO START OFF DRY...WITH NEXT LOW AMPLITUDE FAST
MOVING WAVE SPREADING ACROSS OUR AREA DURING THE LATE MORNING AND
EARLY AFTERNOON. MOISTURE PROFILES LIMITED...AS IS ANY SPECIFIC LOW
LEVEL CONVERGENCE BOUNDARY (PERHAPS WEAK LAKE INFLUENCED BOUNDARY
SOUTH SIDE OF EASTERN UPPER). THAT SAID...MODEL DERIVED SOUNDINGS
NOT TOO TERRIBLE FOR SHOWER DEVELOPMENT...WITH STEEP LOW LEVEL LAPSE
RATES AND PROJECTED ML CAPE NEAR 500 J/KG. ABOVE PROBABLY A TOUCH
AGGRESSIVE...AND WITH NO WELL DEFINED LOW LEVEL CONVERGENCE
BOUNDARIES...WILL TEMPER INHERITED POPS SOME...FEATURING JUST LOW
CHANCE IN CLIMATOLOGICALLY FAVORED AREAS OF EASTERN UPPER AND
NORTHEAST LOWER MICHIGAN. WILL KEEP THUNDER OUT OF THE EQUATION FOR
NOW. TEMPERATURES REMAINING BELOW NORMAL...WITH HIGHS IN THE LOWER
AND MIDDLE 70S.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 355 PM EDT WED JUL 31 2013

THURSDAY NIGHT AND FRIDAY...A COLD FRONT ASSOCIATED WITH A STORM
SYSTEM OVER HUDSON BAY...WILL PUSH INTO THE WRN LAKES THURSDAY
EVENING BEFORE SLOWLY SWEEPING OVER THE STATE FRIDAY. HIGH PRESSURE
WILL THEN QUICKLY BUILD BACK INTO THE UPPER MIDWEST AND WESTERN
GREAT LAKES FRIDAY NIGHT...AS THE COLD FRONT EXITS EAST OF THE
REGION. MODEL SOUNDINGS AND MSTR PROGS SHOWING LIMITED MSTR WILL
HINDER PCPN AMOUNTS AND CHC'S OVR NRN MI THURSDAY NIGHT. HOWEVER
THERE WILL BE SOME MSTR INCREASE OVER THE CWA FRIDAY JUST IN ADVANCE
OF THE COLD APPROACHING FRONT. 850/500MB RH WILL INCREASE FROM
AROUND 40PCT THURSDAY NIGHT TO 80PCT FRIDAY...WHILE MODEL SOUNDINGS
SHOW PWAT VALUES INCREASING TO 90PCT FRIDAY. 850/500MB QVECTORS
SHOWING LIMITED CONVERGENCE WITH APPROACHING COLD FRONT...CONFINED
MAINLY TO RIGHT ALONG THE BOUNDARY.  OVERALL WILL KEEP MOST OF THE
FCST AREA DRY THURSDAY NIGHT...WITH BETTER CHANCES OF RAIN FRIDAY AS
BOUNDARY MOVES ACRS LAKE MICHIGAN. WILL MENTION HIGH TEMPS IN THE
MID 70S OVR THE CWA AIDED IN PART BY SOME SUN AND SOUTHWEST FLOW.

FOR THE WEEKEND...COOL UNSEASONAL CONDITIONS ARE EXPECTED ACRS THE
GREAT LAKES FOR THE FIRST WEEKEND IN AUGUST. AT UPPER LEVELS...
WHICH WILL RESEMBLE MORE THAT OF MID WINTER INSTEAD OF MID
SUMMER...A 500MB LOW WILL BECOME CENTERED OVER HUDSON BAY THROUGH
THE WEEKEND. WHILE AT THE SURFACE...AN AREA OF CANADIAN HIGH
PRESSURE WILL BUILD INTO THE NRN PLAINS AND GREAT LAKES THRU THE
WEEKEND. TEMPS WILL TREND BELOW NORMAL THRU SUNDAY...AS THE HUDSON
BAY 500MB LOW FORCES COLD 850MB TEMPS INTO THE REGION. 850MB TEMPS
WILL COOL FROM AROUND 11C FRIDAY TO BTWN 6C AND 8C BY SUNDAY.
CURRENT TRENDS CONT TO INDICATE DRY CONDS OVER NRN MI THIS WEEKEND
THOUGH SOME LAKE INFLUENCES ARE POSSIBLE. SUSPECT THE DRY AIR MOVING
INTO THE GREAT LAKES WILL LIMIT LAKE EFFECTS TO MAINLY CLOUDS...AS
850/500MB RH DIMINISHES TO UNDER 40 PCT. WILL KEEP AFTN TEMPS COOL
THROUGH THE WEEKEND...IN THE UPPER 60S TO LOWER 70S ACRS NRN MI...
AS 850MB TEMPS FALL TO AROUND 6C.

LINGER AROUND 6C TO BEGIN THE UPCOMING WORK WEEK...KEEPING AFTN HIGHS
IN THE LOWER 70S. SMALL CHANCES OF SHOWERS WILL EXIST THROUGH THE
PERIOD...AS HIGH PRESSURE FROM THE WEEKEND EXITS EAST AND A WEAK
SYSTEM TRIES TO ORGANIZE OVER THE NRN PLAINS AND UPPER MIDWEST.
PCPN AMOUNTS AND CHC WILL BE HINDERED GREATLY BY LIMITED MOISTURE
AS 850/500MB RH REMAINS AROUND 60PCT.
