AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
430 AM EDT THU APR 2 2015

.NEAR TERM...(TODAY THROUGH TONIGHT)
ISSUED AT 425 AM EDT THU APR 2 2015

...RAIN DEVELOPS THIS MORNING AND ENDS LATE IN THE DAY...

HIGH IMPACT WEATHER POTENTIAL: MINIMAL.

PATTERN SYNOPSIS/FORECAST: MIDNIGHT SURFACE ANALYSIS SHOWS A
COLD/OCCLUDED FRONT STRETCHING FROM A 994MB LOW OVER NORTHWEST
ONTARIO...ACROSS EASTERN MINNESOTA/NORTHWEST IOWA/SOUTHEAST
NEBRASKA.  TRIPLE POINT NEAR DLH WITH A WARM FRONT EXTENDING
SOUTHEAST INTO WISCONSIN...OUTFLOW BOUNDARY JUST AHEAD OF THE COLD
FRONT ASSOCIATED WITH AN ELONGATED SQUALL LINE FROM NORTHWEST
WISCONSIN BACK INTO IOWA.  PRECIPITATION ALSO EXTENDED EAST ACROSS
UPPER MICHIGAN...MOSTLY AS RAIN THOUGH EARLIER HAD BEEN SOME SNOW
AND EVEN FREEZING RAIN REPORTED AT THE SOO (ICE SENSOR PICKED UP
AROUND .05 INCH ICE ACCUMULATION...WITH SOME OTHER REPORTS OF THIN
GLAZING ON ELEVATED SURFACES).  MEANWHILE TEMPERATURES ARE STILL
MILD ACROSS NORTHWEST LOWER WITH 50S AND EVEN SOME LOWER 60S ALONG
THE LAKE MICHIGAN SHORELINE (ALONG WITH WINDS GUSTING 30-40MPH).
SHORT WAVE TROUGH MOVING THROUGH NORTH DAKOTA/MANITOBA...WITH
ANOTHER COMPACT SHORT WAVE TROUGH TRACKING NORTHEAST INTO ILLINOIS.
THIS LATTER FEATURE IS SUPPORTING SOME CONVECTION ACROSS ILLINOIS
DOWN INTO ARKANSAS/TENNESSEE.  NARROW LOW LEVEL THETA-E RIDGE ALONG
THE COLD FRONT SUPPORTING SQUALL LINE... INSTABILITY IS THINNING
ALONG THE NORTHERN PORTION OF THE LINE ACROSS WISCONSIN.

COLD/OCCLUDED FRONT WILL SLIDE ACROSS THE FORECAST AREA LATER TODAY
ALONG WITH SOME SUPPORTING MID LEVEL SHORT WAVE ENERGY.  THIS WILL
BE FOLLOWED BY A SECONDARY COLD FRONT (AND STRONGER COLD AIR PUSH)
WILL CROSS NORTHERN MICHIGAN OVERNIGHT.  SUPPORTING SHORT WAVE
ENERGY WITH SECOND COLD FRONT WILL PASS MOSTLY NORTH OF THE FORECAST
AREA.

PRIMARY FORECAST CONCERNS: RAIN TODAY...IMPACT OF SECOND COLD FRONT
TONIGHT.  THUNDER THREAT LOOKING MORE MUTED.

TODAY...EXPECT PRECIPITATION CHANCES TO RAMP UP THIS MORNING...WITH
INCREASING SYNOPTIC FORCING ASSOCIATED WITH FRONTAL CIRCULATION AND
SUPPORTING SHORT WAVE ENERGY INTERACTING WITH INCREASING LOW LEVEL
MOIST INFLOW.  MAY BE TWO AREAS OF PRECIP TO WATCH FOR TODAY...ONE
CLOSER TO THE APPROACHING COLD FRONT (INDEPENDENT OF WEAKENING
SQUALL LINE REMNANTS THIS MORNING)...SECOND ALONG SHORT WAVE ENERGY
LIFTING NORTHEAST ACROSS ILLINOIS THAT WOULD PUSH ACROSS LOWER
MICHIGAN FROM THE SOUTHWEST.  BEST CHANCE FOR THUNDER SHOULD BE WITH
THE SHORT WAVE TROUGH ACROSS NORTHERN LOWER DURING THE FIRST HALF OF
THE DAY...WITH LOW LEVEL THETA-E RIDGE SHIFTING EAST OF THE STATE
DURING THE AFTERNOON.  STRONG DRYING/LARGE SCALE SUBSIDENCE ON THE
BACK SIDE OF THE FRONTAL CIRCULATION EXPECTED TO BRING RAIN TO AN
END FROM WEST TO EAST DURING THE MID TO LATE AFTERNOON HOURS.
RAINFALL TOTALS FOR TODAY SHOULD BE GREATEST ACROSS NORTHERN
LOWER...WITH 0.25+ INCH RAINFALL AMOUNTS EXPECTED SOUTH OF AN FKS-
PZQ LINE.  CLOUDS EXPECTED TO DECREASE DURING THE LATE AFTERNOON AS
WELL.  GUSTY WINDS AT TIMES THIS MORNING EXPECTED TO DIMINISH AS
GRADIENT WEAKENS AND WITH LOSS OF MIXING AS PRECIP DEVELOPS.

TONIGHT...SECOND COLD FRONT NOT EXPECTED TO ARRIVE UNTIL THE PRE-
DAWN HOURS OF FRIDAY...WITH PLENTY OF CLOUDS AND SNOWFALL BEHIND
THIS FRONT ACROSS THE CANADIAN PRAIRIES.  BUT THIS SYSTEM IS IN THE
PROCESS OF WEAKENING/OPENING UP...AND EXPECTED TREND IS THAT
ASSOCIATED PRECIPITATION WILL FALL APART AND NOT IMPACT THE REGION
BY THE TIME THE COLD FRONT ARRIVES.  SOME POST-FRONTAL LOW CLOUDS
MAY SPREAD ACROSS THE UPPER PENINSULA TOWARD MORNING.

&&

.SHORT TERM...(FRIDAY THROUGH SATURDAY NIGHT)
ISSUED AT 425 AM EDT THU APR 2 2015

HIGH IMPACT WEATHER POTENTIAL: NONE

WHAT'S THAT? YOU THOUGHT THAT FORAY INTO SPRING-LIKE TEMPERATURES
WOULD LAST? APRIL FOOLS! BACK TO REALITY AS WE WRAP UP THE WORK WEEK
AND WELCOME THE FIRST PART OF THE WEEKEND...WITH OVERALL
TEMPERATURES TRENDING BACK WELL BELOW NORMAL ONCE AGAIN (UGH...).
MODEST COLD ADVECTION LOOKS TO BE UNDERWAY THROUGH ABOUT MIDDAY
FRIDAY IN OUR POST-FRONTAL ENVIRONMENT...ALL WHILE WEAKISH LOW LEVEL
RIDGING MAKES ITS BEST ATTEMPT TO WORK INTO THE NORTHERN
LAKES...BRANCHING OFF MORE PRONOUNCED RIDGING OVER THE PLAINS/
CANADIAN PRAIRIE. EXCELLENT DRYING ALOFT INTO FRIDAY SHOULD REALLY
PUT THE KIBOSH OF ANY PRECIP CHANCES...WITH ALL SIGNS POINTING
TOWARD A MORE SOUTHERLY SOLUTION WITH REGARD TO A FRONTAL WAVE
RIDING BY JUST TO OUR SOUTH. THERMAL REGIME WITH H8 TEMPS AROUND -
10C COMBINED WITH A VERY WEAK NORTHERN STREAM FEATURE APPROACHING
INTO THE AFTERNOON MAY BE ENOUGH TO SPREAD SOME BETTER STRATOCUMULUS
ACROSS THE AREA (ENHANCED DIURNALLY BENEATH THE CHILL ALOFT)...WITH
MAYBE A FEW FLURRIES AS WELL GIVEN CLOUD TOP TEMPS RUNNING NEAR -
12C. SHOULD NOT BE A BIG DEAL WITH THE BIGGER STORY BEING HIGH TEMPS
BACK IN THE 30S TO PERHAPS MID 40S SOUTHEAST SECTIONS WHERE
DOWNSLOPE NORTHWEST FLOW WILL HELP.

LOOKING QUIET INTO FRIDAY NIGHT AND SATURDAY AS WELL...WITH PERHAPS
A LITTLE PESKY FLURRY ACTIVITY DURING THE AFTERNOON AS WE SEE A
NARROW RIBBON OF QUITE WEAK MID LEVEL FRONTOGENESIS TRY TO SNEAK
OVERHEAD. HONESTLY THIS DOESN'T LOOK LIKE A BIG DEAL EITHER AT THE
MOMENT...BUT WILL NEED TO MONITOR AS THERE COULD BE A VERY NARROW
CORRIDOR OF A LITTLE BIT BETTER SNOW STRADDLING THE SOUTHERN CWA
(SIMILAR TO RECENT SIMILAR FGEN EVENTS). SATURDAY NIGHT IS A LITTLE
BIT DIFFERENT ANIMAL AS WE AWAIT THE ARRIVAL OF A BETTER PUSH OF
LOW/MID LEVEL FRONTOGENESIS AS THE FLOW FLATTENS OUT ALOFT AND WE
REALLY TIGHTEN THE BAROCLINICITY OVER THE GREAT LAKES. THIS ONE HAS
DEFINITE POTENTIAL TO PRODUCE SOME SNEAKY LOCALIZED HEAVIER SNOW
AMOUNTS...THOUGH PLACEMENT IS STILL VERY MUCH OF LOW CERTAINTY. AT
THE MOMENT...RECENT TRENDS WOULD SUPPORT THIS BEING A MAINLY
NORTHERN LOWER ISSUE BUT WILL OF COURSE CONTINUE TO MONITOR.

&&

.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 425 AM EDT THU APR 2 2015

HIGH IMPACT WEATHER POTENTIAL: UNCERTAIN. CHANCES FOR A VARIETY OF
PRECIPITATION TYPES WILL EXIST FROM SUNDAY THROUGH MIDWEEK...THOUGH
THE TIMING...AMOUNT...AND EXACT TYPE(S) OF PRECIPITATION REMAIN TO
BE SEEN.

AN ACTIVE STRETCH OF WEATHER FOR SURE AS WE HEAD THROUGH THE FIRST
PART OF NEXT WEEK. RE-EMERGENCE OF THE WESTERN TROUGH WILL BUCKLE
THE FLOW MORE SOUTHWESTERLY OVER THE CENTRAL AND EASTERN CONUS...
WITH STRONG JET ENERGY AND HEIGHT FALLS FAVORING LEE CYCLOGENESIS
SOMEWHERE OVER THE CENTRAL PLAINS. THAT SETUP WILL DRIVE A WARM
FRONT (BOTH AT THE SURFACE AND ALOFT) NORTHWARD INTO THE GREAT
LAKES...ALL WHILE STRONGER MID LEVEL CONFLUENCE OVER SOUTHEAST
CANADA MAINTAINS HIGH PRESSURE JUST TO OUR NORTH. THIS IS A RATHER
CLASSIC SETUP FOR NORTHERN MICHIGAN TO DEAL WITH SNEAKY
PRECIPITATION TYPE ISSUES EARLY IN THE SPRING...AS THAT HIGH TO THE
NORTH FUNNELS IN A CONSISTENT SUPPLY OF COLDER AND DRY AIR WHILE
STRONG SOUTHERLY FLOW ALOFT TRANSPORTS GULF MOISTURE NORTHWARD TO
OVERRUN THAT COLDER AIR. IN FACT...SOME OF OUR BEST SPRINGTIME SNOW
AND/OR WINTRY PRECIPITATION EVENTS HAVE COME FROM SUCH SETUPS...AND
THUS THE CONCERN HEADING THROUGH THE PERIOD.

HOWEVER...IT ALL COMES DOWN TO THE PLACEMENT AND DEGREE OF COLD AIR
INTACT OVER NORTHERN MICHIGAN. RIGHT NOW...CONFIDENCE IS INCREASING
THAT ALL AREAS WILL SEE SEVERAL ROUNDS OF PRECIPITATION SUNDAY
THROUGH WEDNESDAY...WITH PERHAPS SIGNIFICANT AMOUNTS OF LIQUID AS
PWAT VALUES SURGE TO NEAR AN INCH OVER THE LOWER LAKES. JUST WHAT
FORM IT FALLS IN IS HIGHLY QUESTIONABLE...WITH QUITE HONESTLY JUST
ABOUT ANY PRECIP TYPE (OR ALL OF THEM) POSSIBLE AT VARIOUS TIMES.
REALLY LIKE THE CURRENT MENTION IN THE HAZARDOUS WEATHER OUTLOOK AND
IT WILL REMAIN AS THE POSSIBILITY DOES EXIST FOR DISRUPTIVE
CONDITIONS FOR PARTS OF THE AREA. STAY TUNED...

GUSTY SOUTH WINDS THIS MORNING EXPECTED TO DIMINISH AS GRADIENT
WEAKENS WITH COLD FRONT PASSAGE. SMALL CRAFT ADVISORIES WILL

ZONES TO GALE WARNINGS FOR THIS MORNING. SECONDARY COLD FRONT
PASSAGE LIKELY TO KEEP WINDS GUSTY ON WHITEFISH BAY LATER TONIGHT
SO WILL EXTEND SMALL CRAFT ADVISORY THROUGH THE NIGHT THERE.
GUSTY NORTHWEST WINDS TO START THE DAY FRIDAY WITH COLD ADVECTION
AND SOME ISALLOBARIC SUPPORT.
