AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
441 AM EDT TUE APR 15 2008

.SYNOPSIS...
08Z WATER VAPOR LOOP AND RUC 500MB HEIGHT ANALYSIS SHOWED AN UPPER
LEVEL TROUGH OVER THE PACIFIC NW...RIDGING ACROSS THE PLAINS INTO NW
ONTARIO...AND TROUGHING OVER THE EASTERN U.S.. SINCE UPPER MI IS NOW
CLOSE TO THE RIDGE AXIS...SURFACE HIGH PRESSURE IS CENTERED TO THE
SOUTH FROM LOWER MI TO THE NW GULF OF MEXICO...AND THEREFORE IN
RETURN FLOW. THE RETURN FLOW IS NOT THAT STRONG YET...NOTED BY A
WEAKER PRESSURE GRADIENT OVER UPPER MI COMPARED TO THAT OVER THE
DAKOTAS AND MN...WHICH ARE CLOSER TO 991MB LOW PRESSURE IN NE
MONTANA. RETURN FLOW DOES NOT HAVE MUCH MOISTURE SINCE THE HIGH
PRESSURE AREA EXTENDS INTO THE GULF. 00Z SOUNDINGS ACROSS MUCH OF
THE PLAINS AND  MIDWEST DEPICT THE DRY AIR THROUGHOUT THEIR PROFILE.
HOWEVER... PLENTY OF WARM AIR IS PRESENT...WITH 850MB TEMPS AT 00Z
OF 0C AT INL AND CWPL...AND THEN RAPIDLY RISE TO 12C AT ABR...13C AT
BIS AND 22C AT UNR. HIGH TEMPS YESTERDAY ACROSS THE NORTHERN PLAINS
REFLECT THE WARM 850MB TEMPS...WITH READINGS IN THE 70S TO LOW 80S
ACROSS THE WESTERN DAKOTAS...MONTANA AND SOUTHERN SASKATCHEWAN.
GIVEN THE DRY AIRMASS ACROSS THE MIDWEST...ONLY CLOUD COVER TO SPEAK
OF ARE HIGH CLOUDS...WHICH ENCOMPASS MUCH OF SOUTH CENTRAL
CANADA...NORTH DAKOTA...NRN MN AND NW ONTARIO. THESE CLOUDS ARE
ASSOCIATED WITH A STREAM OF UPPER LEVEL MOISTURE OFF THE
PACIFIC...WHICH RIDES UP INTO SOUTH CENTRAL CANADA BETWEEN THE
PACIFIC NW UPPER TROUGH AND THE CENTRAL PLAINS RIDGE.

&&

.DISCUSSION...
MAIN FORECAST CONCERNS ARE TEMPS THROUGH WED NIGHT AND SNOWMELT.

TODAY AND TONIGHT...UPPER RIDGE AXIS OVER NW ONTARIO CROSSES UPPER
MI THIS MORNING...THEN THE AREA IS PLACED UNDER SW FLOW THROUGH
TONIGHT AS THE UPPER TROUGH OVER THE PACIFIC NW MOVES INTO THE
ROCKIES. AS NOTED IN THE SYNOPSIS...AIRMASS ACROSS THE CENTRAL U.S.
IS VERY DRY...SO NO CONCERN EXISTS FOR PCPN. MAIN CONCERNS IS HOW
BREEZY IT WILL BECOME TODAY AND HOW WARM TEMPS ARE. TIGHT PRESSURE
GRADIENT OVER THE NORTHERN PLAINS CURRENTLY IS PROGGED TO SHIFT OVER
THE CWA THIS AFTERNOON...AND PERHAPS GET A BIT TIGHTER AS THE LOW IN
NE MONTANA SHIFTS INTO NORTH DAKOTA AND DEEPENS TO AROUND 988MB.
MODELS REFLECT THIS BY SHOWING 925MB WINDS INCREASING TO 35-40 KT BY
21Z...AND EVEN 45-50KT OVER THE WESTERN U.P.. NEXT QUESTION THEN IS
HOW MUCH SUN DO WE SEE TO HELP MIX THESE DOWN. MODELS DEPICT THE
CIRRUS DECK TO OUR NW SPREADING IN HERE ATTM DISSIPATING THROUGH THE
DAY WEST TO EAST. SO IT LOOKS LIKE A DECENT AMOUNT OF SUN WILL BE
REALIZED. GIVEN THE DRY AIRMASS...STRONG WINDS OUT OF THE SW
DIRECTION AND PLENTY OF SUN...IT WOULD SEEM A STRONG MIXING DAY IS
IN ORDER. MODELS SOUNDINGS STILL SEEM TO HAVE A HARD TIME BRINGING
MIXING HEIGHTS TO 850MB...WHICH MAY HAVE SOME CREDIT SEEING THE 00Z
SOUNDING FROM BIS ONLY MIXING TO 870MB. BEST GUESS IS THAT THE
CIRRUS IS HAVING SOME IMPACT. LOOKING BACK AT APRIL 15 2002...WHEN
WE HIT OUR RECORD HIGH OF 76...THE 00Z SOUNDING FOR THE 16TH AT GRB
MIXED UP TO 875MB WHEN EVEN WARMER TEMPS ADVECTED IN TO STRENGTHEN
THE INVERSION (00Z 850MB TEMP WAS 18C). OUR 850MB TEMPS ARE ONLY
PROGGED TO REACH 6 TO 12C...WITH THE WARMEST READINGS IN THE
DOWNSLOPE AREAS OF THE WESTERN U.P.. GIVEN THE TWO SOUNDINGS
DESCRIBED...DECIDED TO USE A GENERAL MIXING HEIGHT OF 875MB TODAY.
THIS RESULTS IN HIGHS A LITTLE COOLER THAN THE PREVIOUS FORECAST.
GIVEN THE MIXING HEIGHTS...CONCERN EXISTS OF REACHING WIND ADVISORY
CRITERIA...PARTICULARLY FOR THE DOWNSLOPE AREAS. WITH THE RUC 13
SHOWING GUSTS AROUND 40 KT FOR BARAGA...MARQUETTE...ONTONAGON AND
GOGEBIC COUNTIES THIS AFTERNOON...DECIDED TO ISSUE A WIND ADVISORY
FOR THESE AREAS. GIVEN THE MIXING...DEWPOINTS SHOULD CRASH. THUS A
GOOD SETUP IS IN PLACE FOR FIRE WEATHER ISSUES...EXCEPT FOR A FAIRLY
THICK SNOWPACK. ON THE OTHER SIDE OF THE COIN...THE LOWER DEWPOINTS
SHOULD HELP PREVENT A QUICK SNOWPACK MELT. FOR TONIGHT...THE
PRESSURE GRADIENT STAYS TIGHT...WHICH WILL HELP MAINTAIN BREEZY
CONDITIONS AND LIMIT TEMP FALL. SOME DOWNSLOPE AREAS MAY STRUGGLE TO
DROP MUCH BELOW 50F.

WED AND WED NIGHT...UPPER TROUGH OVER THE WESTERN U.S. IS PROGGED TO
SPLIT INTO TWO PARTS DUE TO THE STRONG RIDGING DOWNSTREAM OVER THE
EASTERN U.S.. MAIN FEATURE OF INTEREST THAT COULD PROVIDE SOME UPPER
FORCING FOR PCPN IS A FAIRLY STRONG SHRTWV INDICATED OVER SOUTHERN
WYOMING AT 12Z WED. THIS SHRTWV MOVES NE INTO NRN MN BY 00Z
THU...BRINGING THE SURFACE LOW THAT WAS OVER THE DAKOTAS INTO NE MN.
ALTHOUGH THE LOWS COLD FRONT IS APPROACHING...WHICH DOES HELP TO
BRING MORE MOISTURE UP INTO THE CWA AS INDICATED BY PRECIPITABLE
WATERS RISING TO 0.75 IN...CAPPING EXISTS ALOFT. IN ADDITION...THE
OVERALL AIRMASS IS STILL FAIRLY DRY...SO HAVE REMOVED ANY PCPN AHEAD
OF THE FRONT. BEHIND THE FRONT FOR WED NIGHT...CARRIED SOME LOW
CHANCE POPS ACROSS THE CWA AS DPVA FROM THE SHRTWV APPROACHES. NOT
VERY IMPRESSED BY THIS EITHER SINCE A LOT OF THE FORCING HEADS
NORTH. THEREFORE REDUCED POPS TO 20 AND THESE OVER UPPER MI COULD BE
REMOVED WITH THE NEXT FORECAST. TEMPS FOR WED ARE SOMEWHAT
INTERESTING. UPPER LEVEL MOISTURE FEED CURRENTLY STREAMING ON THE
WEST SIDE OF THE RIDGE APPEARS TO SHIFT EASTWARD INTO THE CWA
THROUGH THE DAY...MEANING A GRADUAL INCREASE IN CLOUD COVER WEST TO
EAST. HOWEVER...WITH A BREEZY SW FLOW CONTINUING BUT NOT AS STRONG
AS TODAY...WARMER TEMPS TO START OFF AND STILL QUITE A BIT OF
SUNSHINE...THINK SOME DECENT MIXING SHOULD OCCUR. IN FACT...MODEL
SOUNDINGS DEPICT HIGHER MIXING HEIGHTS...PERHAPS UP TO 825MB.
THEREFORE...DESPITE THE INCREASING CLOUD...THINK WED WILL PROBABLY
BE THE WARMEST DAY AND MORE CONFIDENT OF 70F OCCURRING IN BARAGA AND
MARQUETTE. LOOKING BACK AT THE 00Z SOUNDING FOR GRB ON APRIL 17 2002
(WE HIT 83 ON THE 16TH)...THE SOUNDING MIXED UP TO 800MB DESPITE
HAVING MORE MOISTURE...FOLLOWING A SIMILAR TREND TO WHAT IS PROGGED
FOR THIS YEARS 15TH AND 16TH. DEWPOINTS ARE EXPECTED TO MIX
SOME...BUT SHOULD BE AT OR ABOVE FREEZING. SINCE SNOWPACK
TEMPERATURES WILL BE SOLIDLY AT 32F... CONDITIONS LOOK FAVORABLE FOR
THE SNOW TO MELT QUICKLY. IN ADDITION...KEPT FAIRLY WARM TEMPS IN
FOR WED NIGHT (MOSTLY 40S) WITH A SLOW FRONTAL PASSAGE...WHICH MEANS
MELTING WILL CONTINUE THROUGH THE NIGHT. MAY HAVE TO WATCH RIVER
LEVELS AS WE GET INTO WED NIGHT AND ESPECIALLY THU.

THU THROUGH FRI NIGHT...NORTHERN PORTION OF THE UPPER LEVEL TROUGH
SLOWLY APPROACHES THE CWA DURING THIS PERIOD...EVENTUALLY CROSSING
THE CWA SOME POINT ON FRI. MEANWHILE TO THE SOUTH...THE SOUTHERN
PORTION OF THE UPPER TROUGH IS EXPECTED TO SHIFT EASTWARD INTO THE
CENTRAL PLAINS AS AN UPPER LOW. FOR THU INTO THU NIGHT...MAIN FOCUS
OF ATTENTION IS THE DPVA FORCING FROM THE NORTHERN PORTION OF THE
UPPER TROUGH...AND MID-LEVEL FRONTOGENESIS PROGGED TO DEVELOP BEHIND
THE COLD FRONT THAT PASSED THROUGH THE AREA WED NIGHT. THESE TWO
MECHANISMS WILL HELP TO GENERATE A BAND OF PCPN...WHICH MODEL
CONSENSUS SEEMS TO BE FROM NE IA INTO SE UPPER MI/NRN LAKE MI BY
LATE THU...THEN SLOWLY SHIFT EAST THU NIGHT AS THE UPPER TROUGH
MOVES INTO THE CWA. HAVE ADJUSTED POPS ACCORDINGLY FOR THE CONSENSUS
AXIS. FOR FRI...THE GFS WANTS TO TAKE THE UPPER LOW NORTHWARD...
WHICH RESULTS IN PCPN INTO THE EASTERN CWA FRI INTO FRI NIGHT.
PREFER THE MORE SUPPRESSED IDEA OF THE 00Z ECMWF/UKMET/CANADIAN...
ESPECIALLY WITH THE PASSAGE OF THE NORTHERN STREAM UPPER TROUGH
WHICH RESULTS IN CONFLUENT UPPER FLOW OVER THE CWA. THEREFORE...WILL
CONTINUE WITH A DRY FORECAST FOR FRI AND FRI NIGHT. WITH A BIT MORE
CLOUD COVER OVERALL DURING THIS PERIOD AND NE LOW LEVEL FLOW...IN
ADDITION TO 850MB TEMPS COOLING TO 0-2C ON THU...EXPECT TEMPS TO BE
A BIT COOLER. GOING FORECAST TEMPS LOOK REASONABLE.

NO CHANGES MADE BEYOND FRI NIGHT. UPPER LEVEL TROUGH PROGGED TO DROP
DOWN INTO THE PACIFIC NW ON SAT WHICH WILL PUSH MORE UPPER RIDGING
OVER THE CWA...AND THEREFORE WARMER AIR. WHAT HAPPENS WITH THIS
UPPER TROUGH EARLY NEXT WEEK LOOKS INTERESTING...PARTICULARLY WITH
THE 00Z ECMWF AND FOR AREAS IN THE NORTHERN PLAINS. BASICALLY THE
NEW ECMWF CREATES A 998MB LOW OVER SOUTH CENTRAL CANADA AT 12Z
TUE...WITH WESTERLY FLOW BELOW IT ADVECTING 850MB TEMPS OF -12C
EASTWARD TO INL. THIS COLD AIR STAYS AWAY FROM HERE THROUGH THE REST
OF ITS RUN...BUT SOMETHING TO WATCH.

&&

.AVIATION (FOR THE 06Z TAF ISSUANCE)...

VFR CONDITIONS WILL CONTINUE WITH MID-UPR HIGH PRESSURE RIDGE
DOMINATING. CONTINUED MENTION OF LLWS AT BOTH SITES UNTIL 14Z AS
STRONG SWRLY GRADIENT FLOW DEVELOPS JUST OFF THE SFC BETWEEN
DEPARTING HIGH PRESSURE RIDGE AND APPROACHING TROUGH FROM THE
NORTHERN PLAINS. AFTER INVERSION BREAKS AROUND 14Z TUE...EXPECT SRLY
WINDS TO GUST OVR 30 KT AT BOTH SITES...AND MAY EVEN APPROACH 40 KT
AT KSAW WITH FAVORABLE SRLY FLOW. EXPECT WINDS TO DIE DOWN SOME THIS
EVENING WITH LOSS OF DIURNAL MIXING...BUT KSAW SHOULD STILL GUST TO
25 KT. INCLUDED LLWS AT KCMX WITH WINDS TO 40 KT AROUND 1KFT AS AXIS
OF LOW-LVL JET MOVES OVER THE AREA THIS EVENING.

&&

.MARINE (FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)...

SOUTHERLY WINDS WILL CONTINUE TO STRENGTHEN TODAY INTO THIS EVENING
OVER LAKE SUPERIOR AS A PRESSURE GRADIENT TIGHTENS BTWN HIGH
PRESSURE TO THE EAST AND LOW PRESSURE OVR PLAINS. WARM AIR
OVERRIDING COLD LAKE TEMPS WILL CREATE A STABLE PROFILE AND PROHIBIT
A WIDESPREAD GALE EVENT. WILL KEEP MENTION OF GALE FORCE GUSTS ON
EASTERN LAKE SUPERIOR TUE EVENING. SUSTAINED 30 KNOT WINDS WILL
CONTINUE TODAY INTO WEDNESDAY. WITH STRONG DOWNSLOPING SOUTHERLY
WINDS 35-40 KT...GALE WARNING STILL LOOKS GOOD OVER ERN LAKE
SUPERIOR NEARSHORE AREAS THIS AFTERNOON AND EVENING. HAVE ALSO
POSTED A GALE WARNING FOR SAXON HARBOR TO ONTONAGON NEARSHORE AREAS
THIS AFTERNOON.

AS THE LOW LIFTS INTO NORTHERN ONTARIO ON WED...IT WILL DRAG A FRONT
ACROSS LAKE SUPERIOR WEDNESDAY NIGHT INTO THU. WINDS WILL GENERALLY
DIMINISH TO 25 KNOTS OR LESS BY THIS TIME. EXPECT LIGHT WINDS
THURSDAY INTO SATURDAY AS HIGH PRESSURE MOVES ACROSS THE AREA IN THE
WAKE OF THE FRONT.
