AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
328 AM EDT SUN OCT 19 2014

.SYNOPSIS...
ISSUED AT 319 AM EDT SUN OCT 19 2014

HIGH PRESSURE WILL NOSE INTO MICHIGAN FROM THE SOUTH TODAY...
BRINGING DRY BUT COOL CONDITIONS. LOW PRESSURE WILL MOVE IN FROM THE
NORTHWEST TONIGHT AND MONDAY...AND RAIN IS LIKELY. SOME SPOTTY
SHOWERS COULD CONTINUE EVEN INTO TUESDAY MORNING...BEFORE A LONGER
PERIOD OF DRY WEATHER BEGINS. TEMPERATURES WILL REMAIN RELATIVELY
COOL INTO WEDNESDAY...BUT THEN WILL START TO WARM.

&&

.SHORT TERM...(TODAY THROUGH TONIGHT)
ISSUED AT 319 AM EDT SUN OCT 19 2014

...LIGHT RAIN TONIGHT...

HIGH IMPACT WEATHER POTENTIAL: MINIMAL

PRIMARY FORECAST CHALLENGES: TIMING OF THE RAIN TONIGHT.

CURRENTLY, THE 500 MB PATTERN IS TRANSITIONING TO A MORE AMPLIFIED
PATTERN AS THE ENERGY DIGS INTO THE 500 MB TROUGH IN THE PACIFIC OFF
THE WEST COAST. THIS IS BEGINNING TO INCREASE THE RIDGING ALONG THE
WEST COAST AS MORE ENERGY TRAVELS DOWN THE INTO THE EASTERN TROUGH.
AS THE THIS ENERGY THAT IS TRAVELING DOWN THE 500 MB FLOW IN
MANITOBA HAS NOW DEVELOPED A SFC LOW THAT WILL BRING RAIN SHOWERS
INTO THE UPPER GREAT LAKES BY TONIGHT.

TODAY...THE 500 MB SHORTWAVE RIDGING WILL PASS THROUGH N MICHIGAN
DURING THE DAY, AS WELL AS THE SFC RIDGE AXIS. WITH THE 850 MB RH
<30% AND THE 700-500 MB LAYER RH < 30% THROUGH 18Z, MOST OF THE DAY
WILL REMAIN DRY. IT'S NOT UNTIL AFTER 18Z THAT THE 500 MB ENERGY
BEGINS TO DIG INTO THE FLOW A LITTLE BIT, AND CONTINUES TO DEVELOP
THE SFC LOW THAT IS EXPECTED TO BE ENTERING W LAKE SUPERIOR BY 00Z.
THE WARM ADVECTION OUT AHEAD OF IT LOOKS LIKE THE MODEL MAY HAVE
SHARPENED IT UP INTO A DECENT BAROCLINIC ZONE. MOISTURE AT THIS TIME
LOOKS LIKE IT IS STILL LIMITED UNTIL THE SFC LOW CLOSES INTO THE
UPPER GREAT LAKES. SO WILL KEEP THE CHANCES OF RAIN SHOWERS LIMITED
FOR THE LATE AFTERNOON IN E UPPER.

TONIGHT...BY THIS EVENING HOWEVER, THE MOISTURE LOOKS LIKE IT
INCREASES AS THE 850 MB RH AND THE 700-500 MB LAYER RH ARE BOTH
ABOVE 90% WITH THE DIGGING 500 MB TROUGH AND THE SFC LOW. THE RAIN
LOOKS LIGHT AS THE SFC LOW DOESN'T LOOK PARTICULARLY DEEP, BUT THE
RAIN SHOWERS WILL LIKELY HAVE MEASURABLE RAIN. IT LOOKS LIKE THE SFC
LOW WILL RIDE DOWN THE WARM FRONT AND INTO E UPPER THIS WILL ALLOW
THE DRY SLOT TO TRAVEL IN BEHIND THE SFC LOW AND CUT OFF MOST OF THE
RAIN AFTER 06Z IN NW LOWER. WILL LEAVE SOME CHANCY POPS AS THE 850
MB TEMPERATURES FALL TO AROUND +2C BY 12Z, AS WE GET SOME LAKE
ENHANCEMENT WITH THE LOW OVER THE REGION.

&&

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 319 AM EDT SUN OCT 19 2014

...RAIN CHANCES EARLY IN THE WEEK FOLLOWED BY PLEASANT WEATHER...

HIGH IMPACT WEATHER POTENTIAL...MINIMAL.

DIGGING UPPER TROF WILL AMPLIFY AND SLOW CONSIDERABLY...GRADUALLY
CROSSING NORTHERN MI ON MONDAY. A WEAKER WAVE DIVING INTO THE MAIN
TROF WILL DROP SOUTH ACROSS EASTERN UPPER/NE LOWER MI MON
NIGHT...SLOWING THE EXIT OF MOISTURE AND CORRESPONDING PRECIP. UPPER
LOW CLOSES OFF...REACHING VA BY WED MORNING...WITH SUBSTANTIAL
RIDGING BUILDING INTO THE UPPER MS VALLEY AND WESTERN SUPERIOR.
PRECIP CHANCES WILL LINGER INTO AT LEAST MONDAY NIGHT...ESPECIALLY
IN EASTERN SECTIONS. THAT/S THE MAIN ISSUE TO CONTEND WITH.

MONDAY...1007 MB SURFACE LOW STARTS THE MORNING OVER EASTERN UPPER
MI...AND WILL MOVE SOMEWHAT SLOWLY SE TOWARD THE BASE OF THE BRUCE
PENINSULA AS THE DAY PROCEEDS. WARM CONVEYOR BELT IS ALREADY
ESSENTIALLY TO OUR EAST AT DAYBREAK...BUT EXTENSIVE COLD CONVEYOR
BELT EXTENDS ACROSS NE LOWER...EASTERN UPPER...AND SUPERIOR...WHILE
A DRY SLOT IS MAKING INROADS INTO NW LOWER. THE DRY SLOT WILL
EVENTUALLY GET SHUNTED OFF TO THE EAST AND SOUTH...ALLOWING DEEPER
MOISTURE TO OVERSPREAD THE ENTIRE FORECAST AREA. HOWEVER...BY
AFTERNOON WE ARE SEEING A SLIGHT RISE IN 500MB HEIGHTS AS THE UPPER
TROF REACHES LAKE HURON. OVERALL...THE MODELS ARE NOT IMPRESSED WITH
FORCING FOR ASCENT IN THE COLD CONVEYOR BELT...AND ARE NOT TERRIBLY
WET. MODELS OFTEN UNDERDO PRECIP IN THE WRAPAROUND ZONE...AND WILL
LEAN THE FORECAST A BIT TOWARD THE WET SIDE. THAT STILL ONLY
WARRANTS LIKELY POPS IN THE MORNING IN EASTERN UPPER/NE LOWER
MI...OTHERWISE CHANCE POPS SUFFICE.

HIGH TEMPS NEAR 50F TO THE MID 50S.

MON NIGHT/TUESDAY...BACK EDGE OF THE WRAPAROUND MOISTURE SHIELD WILL
EXIT EASTERN UPPER/NW LOWER MI MONDAY NIGHT...AND NE LOWER TUESDAY.
THE SECONDARY SHORTWAVE WILL DROP SOUTH ACROSS NORTHERN/EASTERN
SECTIONS ON MON NIGHT...SLOWING THE EXIT OF THE MOIST SHIELD AND
ALSO PROVIDING SOME SEMBLANCE OF LIFT. WILL KEEP POPS ON THE HIGH
SIDE IN NE LOWER (CAN MAKE THE CASE FOR LIKELY POPS AGAIN FROM
ROGERS TO APN AND OSC...BUT WILL HOLD OFF FOR NOW). WILL HANG ONTO A
SLIGHT CHANCE OF SHRA IN NE LOWER MI TUE MORNING. OTHERWISE WILL BE
DRYING AND CLEARING THINGS OUT TUESDAY...AS HIGH PRESSURE IN
NORTHERN ONTARIO EXTENDS SUBSTANTIAL RIDGING INTO THE NORTHERN/
WESTERN LAKES BY AFTERNOON.

STILL RATHER COOL...WITH MIN TEMPS IN THE MID 30S TO NEAR
40F...AND MAX TEMPS MID 40S TO NEAR 50F.

REST OF THE FORECAST...UPPER RIDGE AXIS BUILDING INTO THE WESTERN
LAKES WILL KEEP WED DRY AND FAIRLY SUNNY. MODELS CONTINUE TO SEND
MIXED SIGNALS REGARDING A POTENTIAL SHORTWAVE BUTTING INTO THE RIDGE
AND MAYBE FORCING A FEW SHRA ON THURSDAY. IN A FLIP-FLOP FROM
YESTERDAY...IT IS THE ECMWF WITH THE MORE PROGRESSIVE AND
POTENTIALLY WETTER SOLUTION...WHILE THE GFS IS MORE AMPLIFIED AND
MUCH SLOWER. GIVEN HOW AMPLIFIED THE PATTERN IS IN GENERAL...WILL
GIVE THE GFS A (RARE) CHANCE TO BE CORRECT...AT LEAST FOR ONE MORE
RUN. WILL NOT INCLUDE ANY POPS FOR THU AT THIS TIME. THAT EVENTUALLY
LEADS TO FLATTISH RIDGING OVER THE N CENTRAL STATES LATE IN THE
WEEK...WHILE A LOW CUTS OFF IN TX OR THE LOWER MS VALLEY. THIS IS A
DRY AND MILD PATTERN AS WE HEAD TOWARD NEXT WEEKEND.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1145 PM EDT SAT OCT 18 2014

LOW VFR/HIGH MVFR CIGS WILL HOLD OVER MOST OF OUR NRN LWR MICHIGAN
TAF SITES THRU SUNDAY NIGHT...ESPECIALLY AROUND FAR NW LWR
MICHIGAN (TVC AND MBL) THANKS TO NORTHERLY FLOW...RESIDUAL LOW
LEVEL MOISTURE AND WEAK OVER-LAKE INSTABILITY. LOW LEVEL WINDS
WILL SHIFT TO THE SW ON SUNDAY...BUT LOW/MID CLOUDS WILL INCREASE
FROM NW TO SE AHEAD OF OUR NEXT COLD FRONT. APPEARS ANY RAIN
CHANCES WITH THIS FRONT WILL HOLD OFF UNTIL AROUND 00Z ACROSS NW
LWR MICHIGAN (PLN/TVC/MBL) AND AROUND 03Z FOR NE LWR MICHIGAN (APN).
OVERALL WIND SPEEDS WILL BE AOB 10 KTS THRU THE FORECAST PERIOD.

&&

.MARINE...
ISSUED AT 319 AM EDT SUN OCT 19 2014

WINDS ARE BEGINNING TO BACK TO THE SW NOW, ALTHOUGH MOST OF THE
LAKES HAVE VARIABLE WINDS AT LESS THEN 10 KNOTS THIS MORNING. WITH
THE SFC LOW MOVING INTO THE UPPER GREAT LAKES TODAY, THE GRADIENT
WILL TIGHTEN UP AND THE WINDS WILL BEGIN TO GUST INTO THE SMALL
CRAFT RANGE, MAINLY ALONG THE LAKE MICHIGAN SHORE LINE ADJACENT TO
NW LOWER. THIS WILL MAINLY BE FROM COASTAL CONVERGENCE. TONIGHT, THE
WINDS WILL CONTINUE TO GUST IN LAKE MICHIGAN, ALTHOUGH MAINLY IN THE
EVENING. THE GRADIENT RELAXES AND THE WINDS SHOULD DIMINISH BY 12Z
ON MONDAY. WINDS WILL VEER TO THE NW DURING THE DAY AND PROBABLY
INCREASE SLOWLY THROUGH THE DAY. BY MONDAY NIGHT, THE GRADIENT WILL
HAVE TIGHTENED UP ENOUGH TO GET LOW END SMALL CRAFT ADVISORIES GOING
FOR THE OVERNIGHT PERIOD.
