AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
405 AM EDT MON APR 8 2013
.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 434 PM EDT SUN APR 7 2013
DAYTIME HEATING/MIXING...AND DIMINISHING NORTHWESTERLY WINDS FROM
WEST TO EAST TODAY IS SLOWLY RESULTING IN DIMINISHING CLOUD
COVER...A LITTLE SLOWER THAN ORIGINALLY ANTICIPATED. THE INVADING
SFC HIGH OVER MINNESOTA AND WISCONSIN WILL PUSH OVERHEAD BY 00Z
MONDAY...AND QUICKLY EXIT TO EASTERN UPPER MICHIGAN BY 06Z...AS AN
INVERTED TROUGH OF LOW PRESSURE SET UP ACROSS THE ARROWHEAD OF
MINNESOTA NEARS WESTERN LAKE SUPERIOR. THIS WILL BE THE FOCUS OF OUR
NEXT ROUND OF WET WEATHER...ASSISTED BY THE 250MB JET. AT 09Z MONDAY
IT LOOKS AS IT NORTHERN WI AND FAR WESTERN UPPER MICHIGAN WILL BE IN
THE BEST POSITION TO EXPERIENCE ENHANCED PRECIPITATION.
THE DIFFICULT FORECAST CONTINUES. THE 12Z NAM CAME IT A BIT SLOWER
WITH THE PRECIP /ON THE ORDER OF 1-3 HRS/. ANOTHER POTENTIALLY
SIGNIFICANT CHANGE SHOWS UP FROM 18Z MONDAY THROUGH AT LEAST 00Z
TUESDAY...WITH TEMPS AT AND BELOW 850MB SHOWING UP 2-4C COLDER ON
THE 12Z RUN COMPARED TO THE 06Z RUN. THOUGH STILL NOT AS COLD AT THE
LOWER LEVELS AS THE 06 AND 12Z RUNS OF THE GFS...THEY ARE BECOMING
MORE CONSISTENT WITH TIME. THIS WILL HELP BOOST THE CONFIDENCE IN
OUR WEATHER TYPE FORECAST...BUT AS ALWAYS WHERE TEMPERATURES ARE
HOVERING NEAR THE 0C ISOTHERM...ANY SMALL DEVIATION CAN HAVE LARGE
IMPLICATIONS. WENT AHEAD AN ISSUED A WINTER WEATHER ADVISORY...FOR
LIGHT SNOW AMOUNTS...AND LIGHT FREEZING RAIN LATE TONIGHT THROUGH
MID MORNING MONDAY. THE AREA OF MAIN CONCERN WILL LIKELY BE FROM
JUST EAST OF IRONWOOD TO IRON MOUNTAIN...TO SOUTHERN HOUGHTON
COUNTY. RAN THE ADVISORY UNTIL 15Z...WHICH SHOULD COVER THE PERIOD
WHERE SURFACE TEMPERATURES ARE BELOW FREEZING. THIS ACTUALLY GOES
1-2HRS BEYOND WHAT MAY BE NEEDED...BUT COVERS THE TIME PERIOD OF
HIGHEST UNCERTAINTY. WILL STAY AWAY FROM THE GFS FORECAST OF
MODERATE TO HEAVY SNOW NORTH CENTRAL...AND LEAN MORE TOWARD THE NAM
SOLUTION.
OTHERWISE...THE BELOW NORMAL TEMPERATURES WILL CONTINUE THROUGH
MONDAY...PARTICULARLY FOR HIGH TEMPERATURE READING WHICH AVERAGE IN
THE MID 40S FOR THIS TIME OF YEAR ACROSS MUCH OF THE CWA.
.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 404 AM EDT MON APR 8 2013
MODEL INCONSISTENCY CONTINUES TO INFLUENCE THE FORECAST FOR MUCH OF
THIS WEEK.
MODEL DIFFERENCES APPEAR TO BE GREATEST FOR TUESDAY INTO TUESDAY
NIGHT WITH THE HANDLING OF THE NEXT WAVE EXITING THE UPPER TROUGH
IN THE WESTERN CONUS AND THE STRONG SHORTWAVE MOVING THROUGH
SOUTHERN ONTARIO ASSOCIATED WITH THE NORTHERN STREAM JET. AT THE
SURFACE...INVERTED TROUGH THAT WILL BRING THE PRECIPITATION TO THE
AREA TODAY WILL BE SHIFTING EAST AND LEAD TO NORTHERLY FLOW OVER
THE CWA AS THE SURFACE LOW MOVES EAST INTO THE CENTRAL PLAINS. THIS
NORTHERLY FLOW AND SURFACE RIDGE NOSING EAST INTO THE UPPER GREAT
LAKES FROM A PARENT HIGH IN SASKATCHEWAN DOESN/T SEEM CONDUCTIVE
FOR PRECIPITATION...BUT THAT IS WHAT THE LATEST NAM/GFS/GEM RUNS
SHOW OVER THE SOUTH CENTRAL AS A SHORTWAVE EJECTS NORTHEAST FROM THE
CENTRAL PLAINS. LOOKING AT THE WIND/THERMAL FIELDS...WOULD EXPECT
THE PRECIPITATION ALONG AND LIKELY SOUTH THAN WHAT THEY SHOW WITH A
SHARPER CUTOFF TO THE PRECIPITATION TO THE NORTH WITH THE HIGH
PRESSURE RIDGE AND LIMITED 850MB JET STRENGTH. HPC PREFERENCE DURING
THIS PERIOD IS ALSO TOWARDS THE SOUTHERN SOLUTION. THUS...WILL TREND
TOWARDS A DRIER SOLUTION FOR TUESDAY INTO TUESDAY EVENING ACROSS
MUCH OF THE CWA...BUT KEEP SOME PRECIP IN OVER THE SOUTH CENTRAL FOR
THE AFTERNOON/EVENING TO ACCOUNT FOR THE SHORTWAVE. AS FOR THE
MORNING...ECMWF/GEM/GFS ALL ARE SHOWING SOME LIGHT PRECIPITATION
AFFECTING NORTHERN LAKE SUPERIOR ON TUESDAY MORNING DUE TO THE
STRENGTH OF THE SHORTWAVE MOVING ACROSS FAR NORTHERN LAKE SUPERIOR.
WILL ADJUST POPS SLIGHTLY FARTHER SOUTH ACROSS NORTHEAST LAKE
SUPERIOR AND ADD A MENTION OF FLURRIES TO THE KEWEENAW...NORTH
CENTRAL...AND EAST NEAR LAKE SUPERIOR FOR THE MORNING. WITH THE
DRIER AIR FROM THE HIGH PRESSURE RIDGE TRYING TO WORK IN DURING THE
AFTERNOON...WILL CONTINUE THE TREND TOWARDS PARTLY CLOUDY OVER THE
NORTH HALF OF THE CWA AND KEEP MOSTLY CLOUDY OVER THE SOUTH HALF
WITH THE CLOSER PROXIMITY TO THE PRECIPITATION/SHORTWAVE TO THE
SOUTH.
HEADING INTO LATE TUESDAY NIGHT AND WEDNESDAY...NEXT SHORTWAVE
ENERGY EJECTS OUT OF THE UPPER TROUGH MOVING INTO THE PLAINS AND
THE MODEL DISCREPANCY CONTINUES ON THE LOCATION OF THE WAVE AND
RESULTING PRECIPITATION. ALL OF THESE DIFFERENCES LIE WITH THE
STRENGTH OF THE HIGH PRESSURE RIDGE NOSING INTO THE UPPER GREAT
LAKES REGION AND UPPER LOW ROTATING OVER EASTERN HUDSON BAY. IF
THERE IS ANYTHING TO TAKE FROM THIS PERIOD...IT/S THE CONSISTENCY OF
BEST PRECIPITATION CHANCES OVER THE SOUTHEAST HALF/THIRD OF THE CWA.
WILL CONTINUE TO HIGHLIGHT SOME CHANCE POPS IN THAT AREA AND
DIMINISH TO THE NORTHWEST. WITH THE EXPECTED LOCATION OF THE SURFACE
LOW STILL IN THE CENTRAL PLAINS AND ASSOCIATED TROUGH STRETCHING
NORTHEAST THROUGH THE LOWER GREAT LAKES...THAT IDEA SEEMS
REASONABLE.
NOW ONTO WEDNESDAY NIGHT THROUGH THURSDAY NIGHT. AMAZINGLY...MODELS
ARE COMING INTO BETTER AGREEMENT FOR THIS TIME PERIOD WITH THE HIGH
PRESSURE RIDGE REALLY DOMINATING THE UPPER GREAT LAKES.
MEANWHILE...THE UPPER TROUGH WILL BE EXITING THE PLAINS AND INTO THE
EASTERN CONUS WHILE INTERACTING/PHASING WITH THE NORTHERN ENERGY
DROPPING SOUTH FROM HUDSON BAY. THE ASSOCIATED SURFACE LOW SHOULD BE
MOVING THROUGH THE OHIO RIVER VALLEY AND LOWER GREAT LAKES DURING
THIS TIME...WHICH ONCE AGAIN PUTS THE AREA ON THE NORTHERN REACHES
OF THE PRECIPITATION SHIELD. INTERESTINGLY...THE 12Z ECMWF IS THE
ONLY MEDIUM RANGE MODEL PUTTING PRECIPITATION OVER THE SOUTH
CENTRAL CWA ON WEDNESDAY NIGHT WITH THE OTHER MODELS SLIDING IT
ACROSS THE SOUTH CENTRAL ON THURSDAY. WILL CONTINUE TO HIGHLIGHT
BEST CHANCE OF PRECIPITATION THERE IN THE POPS BUT DIMINISH THE
REST OF THE AREA DUE TO BETTER AGREEMENT ON THE INFLUENCE OF THE
HIGH. WITH 900-850 TEMPS FALLING TOWARDS -11C...LOW LEVEL MOISTURE
AND NORTHEASTERLY FLOW...WOULD EXPECT THERE TO BE SOME LAKE
ENHANCED SHOWERS IN THE KEWEENAW AND NORTH CENTRAL CWA FOR THURSDAY
INTO THURSDAY NIGHT AND MAY EVEN CONTINUE INTO FRIDAY MORNING.
QUIETER WEATHER MAY BE IN STORE FOR THE REST OF FRIDAY AND
INTO SATURDAY...AS A HIGH PRESSURE RIDGE MOVES OVER THE AREA.
TEMPERATURES ALOFT ARE STILL FAIRLY COOL...850MB TEMPS AROUND 5C
BELOW NORMAL...SO WOULD EXPECT BELOW NORMAL TEMPS TO STILL BE IN
PLACE WITH HIGHS IN THE 30S. WITH THE CLEAR SKIES...WILL CONTINUE
THE BELOW NORMAL LOW TEMPERATURE TREND FOR FRIDAY/SATURDAY NIGHTS.
LATE ARRIVING 00Z ECMWF HAS SHIFTED THE LOW FARTHER TO THE NORTHWEST
FOR THURSDAY NIGHT INTO FRIDAY...DUE TO THE NORTHERN/SOUTHERN STREAM
TROUGHS NOT PHASING...AND WOULD PRODUCE A SIGNIFICANT AMOUNT OF SNOW
FOR THE AREA ALL THE WAY INTO FRIDAY NIGHT. WILL BE SOMETHING TO
KEEP AN EYE ON OVER THE COMING DAYS AND WOULD COMPLETELY BUST THE
GOING FORECAST FOR FRIDAY INTO SATURDAY.
SUNDAY WILL PRESENT THE NEXT OPPORTUNITY FOR PRECIPITATION...AS
BOTH THE GFS/ECMWF ARE SHOWING THE NEXT PIECE OF ENERGY EXITING THE
PACIFIC NORTHWEST AND SLIDING EAST ACROSS THE NORTHERN CONUS.
INITIAL PRECIP SHOULD FALL AS SNOW AND THEN QUICKLY MIXING WITH OR
CHANGING TO RAIN FROM WEST TO EAST WITH THE STRONG WARM AIR
ADVECTION ALOFT.
ALL IN ALL...THE BELOW NORMAL HIGH TEMPERATURES WILL CONTINUE
THROUGH THE LONG TERM PERIOD. AN INTERESTING FEATURE TO NOTE IS
THAT OUR OFFICE HAS YET TO REACH 50 DEGREES THIS YEAR. WITH THE
AVERAGE 50 DEGREE DAY OCCURRING ON MARCH 15TH...WE ARE WELL PAST
THAT AND WILL LIKELY NOT REACH IT IN THE NEXT 7 DAYS. THAT WILL PUT
THIS YEAR AS ONE OF THE LATEST FIRST 50S ON RECORD AND HOPEFULLY IT
WON/T REACH APRIL 26TH...LIKE IT DID IN 1965.

NEXT WEATHER SYSTEM ARRIVES LATE TONIGHT AND CONDITIONS WILL
DETERIORATE RAPIDLY AT ALL SITES. LOWER IFR CIGS WILL MOVE INTO CMX

REMAIN THROUGH THE REST OF THE PERIOD. IWD WILL LIKELY EXPERIENCE ALL
RAIN WITH MVFR CONDITIONS ALL DAY WITH SAW AND CMX HAVING A RAIN/SNOW
MIX UNTIL IT WARMS UP ENOUGH BY LATE MORNING TO BE ALL LIQUID.
NORTHEAST UPSLOPE LOWER CIGS WILL COME IN BY EVENING TO IWD.

.MARINE...(FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)
ISSUED AT 434 PM EDT SUN APR 7 2013
HIGH PRESSURE OVERHEAD WILL TRANSITION TO A WEAK TROUGH OF LOW
PRESSURE ON MONDAY...AS THE MAIN LOW SLIDES FROM THE CENTRAL PLAINS
TO LOWER MICHIGAN. FROM TUESDAY THROUGH THURSDAY...LAKE SUPERIOR
WILL BE STUCK BETWEEN LOW PRESSURE TO THE SOUTH...AND HIGH PRESSURE
TO THE NORTH. LOOKING CLOSER TO HOME...A RIDGE OF HIGH PRESSURE
ACROSS LAKE SUPERIOR ON TUESDAY SHOULD LINGER THROUGH THURSDAY
NIGHT...BEFORE STRENGTHENING SLIGHTLY ON FRIDAY...AND INTO THE
WEEKEND. DESPITE THE RIDGE OF HIGH PRESSURE...THE PESKY LOW TO OUR
SOUTH WILL ASSIST IN A COUPLE PERIODS OF STRONGER GUSTS AT OR ABOVE
25KTS TOWARD MID WEEK.
