AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
231 PM EST SAT JAN 21 2012

LATEST UPDATE...LONG TERM...

.SYNOPSIS...(127 PM EST SAT JAN 21 2012)
FAIR WEATHER IS EXPECTED UNTIL SUNDAY NIGHT WHEN LOW PRESSURE MOVES
IN WITH RAIN AND WARMER TEMPERATURES. SOME SNOW IS POSSIBLE BY
MONDAY NIGHT WHEN COLDER AIR WRAPS INTO THE LOW.

&&

.SHORT TERM...(158 PM EST SAT JAN 21 2012)
(TONIGHT THROUGH MONDAY NIGHT)
LOWERED MINS A BIT BELOW GUIDANCE FOR TONIGHT AS SFC HIGH SHOULD
MEAN LIGHT WINDS AND CLEAR SKIES. RETURN FLOW BEGINS TOMORROW AND
WILL HAVE TO WATCH FOR LOW STRATUS RETURNING FROM THE SOUTH
ESPECIALLY BY AFTERNOON. TWEAKED MAX TEMPS DOWN A BIT...ESPECIALLY
UP NORTH TO ACCOUNT FOR THE LOW CLOUDS HANGING ON BEFORE THE
STRENGTHENING SOUTHERLY LOW LEVEL FLOW SCOURS OUT THE INVERSION
SUNDAY NIGHT.

WITH LOW STRATUS IN PLACE TOMORROW AFTERNOON...MAY HAVE TO WATCH FOR
SOME FREEZING DRIZZLE UP NORTH SINCE SOME LIFT IS ALSO SEEN DOWN LOW
IN NAM AND GFS OMEGA CROSS SECTIONS. LEFT IT OUT OF THE FORECAST FOR
NOW.

EXPECT RAIN TO MOVE IN SUNDAY NIGHT ALONG WITH AREAS OF FOG AS
HIGHER DEW POINTS ADVECT OVER SNOW. DID NOT MAKE ANY MAJOR TWEAKS TO
THE POPS AND TIMING OF P TYPE FROM PREVIOUS FORECAST WHICH HAS
BASICALLY BEEN GOING CLOSER TO THE SLOWER AND MORE AMPLIFIED EURO.
RAIN SHOULD BE CHANGING OVER TO SNOW AFTER 18Z MONDAY AND THERE
COULD BE DRY SLOT ACROSS THE FORECAST AREA BY THEN. SOME LAKE
ENHANCED WRAP AROUND SNOWS POSSIBLE MONDAY NIGHT ACROSS THE NW
FORECAST AREA BEFORE LOW PULLS AWAY.

&&

.LONG TERM...(231 PM EST SAT JAN 21 2012)
(TUESDAY THROUGH SATURDAY)
NO MAJOR SYSTEMS ARE EXPECTED TO DIRECTLY IMPACT THE AREA DURING THE
LONG TERM. THE FOCUS OF THE FORECAST WILL TRY TO DETERMINE THE CHCS
OF PCPN THROUGH THE PERIOD AS A SOMEWHAT ZONAL UPPER AIR PATTERN
SHOULD HOLD IN CONTROL THROUGH MOST OF...IF NOT THE ENTIRE PERIOD.

THE MAJOR SYSTEM THAT WILL AFFECT THE AREA SUN NIGHT INTO MON NIGHT
SHOULD BE MOSTLY GONE BY TUE MORNING. CYCLONIC FLOW ALOFT WILL
TRANSITION TO ANTI-CYCLONIC AND THE SUFFICIENTLY COLD AIR FOR LAKE
EFFECT WILL MODERATE...AND ANY SNOW SHOWERS WILL COME TO AN END TUE
MORNING.

THE MODELS HAVE BEEN CONSISTENT IN SHOWING A BREAK IN THE SHORT WAVE
ACTIVITY FOR TUE NIGHT...BEFORE BRINGING THE FIRST IN THE SERIES OF
A FEW WAVES IN ON WED. THERE HAVE BEEN SOME INCONSISTENCIES WITH
REGARD TO THE AMOUNT OF PCPN. EITHER WAY THIS SYSTEM WILL NOT HAVE A
WHOLE LOT OF MOISTURE TO WORK WITH AS THE SRN STREAM AND GULF ARE
SHUT OFF...AND ANY AMOUNTS WILL REMAIN LIGHT.

A COUPLE OF MORE SHORT WAVES WILL AFFECT THE AREA THEN BETWEEN THU
MORNING AND FRI EVENING. THESE WAVES ALSO WILL BE LACKING IN THE
MOISTURE DEPARTMENT...AND THE LACK OF COLD AIR WILL LIMIT LAKE
ENHANCEMENT. WE WILL KEEP A LOW CHC IN THROUGH FRI. MAX TEMPS SHOULD
REACH INTO THE 30S EACH DAY.

OBVIOUSLY WHEN DEALING WITH SHORT WAVES...MORE UNCERTAINTY CROPS UP
AS YOU MOVE OUT FURTHER IN TIME. MODELS HAVE BEEN INCONSISTENT
CONCERNING THE FRI NIGHT AND SAT TIME FRAME. NEW EURO IS TRYING TO
CARVE OUT A STRONGER TROUGH NEARBY WHICH WOULD COOL THE AREA OFF AND
BRING LAKE EFFECT CHCS. THIS WOULD BE VERY LATE ON SAT. WE WILL HOLD
ON TO A DRY FCST FOR THE TIME BEING FOR FRI NIGHT AND SAT...AND FINE
TUNE WITH FUTURE FCST PACKAGES.

&&

.AVIATION...(1239 PM EST FRI JAN 20 2012)
AVIATION IMPACTS WILL BE LIMITED OVER THE NEXT 24 HOURS ACROSS THE
AREA. MAINLY CLEAR SKIES THIS AFTERNOON SHOULD CONTINUE INTO THE
EVENING HOURS. LAKE EFFECT CLOUD CLOVER OFFSHORE OF KMKG SHOULD
REMAIN OFFSHORE AS THE MEAN LOW LEVEL FLOW WILL REMAIN OFFSHORE.

HIGH CLOUDS AHEAD OF THE NEXT SYSTEM WILL MOVE IN LATE THIS EVENING
AND OVERNIGHT TONIGHT. WINDS WILL START TO INCREASE TONIGHT...
HOWEVER EARLY DECOUPLING WITH THE FRESH SNOWFALL SHOULD LIMIT THE
WIND POTENTIAL. WINDS WILL PICK UP ON SUN OUT OF THE SE. ONE SET OF
DATA IS TRYING TO DEVELOP SOME STRATUS LATE TONIGHT. THE DRY AIRMASS
IN PLACE AND LITTLE IF ANY MELTING WITH COLD TEMPS TODAY SHOULD KEEP
BOUNDARY LAYER MOISTURE LIMITED.

WE BELIEVE THAT IT WILL BE LATER ON SUN /BEYOND 18Z SUN/ WHEN ABOVE
FREEZING DEW POINTS ADVECT IN OVER THE SNOWPACK ON INCREASING WINDS
THAT THE LOW CLOUD POTENTIAL WILL BE MUCH HIGHER. THIS WILL NEED TO
BE MONITORED.

&&

.MARINE...(127 PM EST SAT JAN 21 2012)
ISSUED A SMALL CRAFT ADVISORY FOR LATE TONIGHT NORTH OF WHITEHALL.
WILL PROBABLY NEED TO EXPAND THIS FOR TOMORROW AND MAY EVEN NEED A
GALE WARNING FOR SUNDAY NIGHT AND MONDAY DEPENDING ON THE STRENGTH
OF THE NEXT STORM.
&&

.HYDROLOGY...(127 PM EST SAT JAN 21 2012)
ICE JAM HAS FORMED NEAR DIMONDALE AND SOME FLOODING IS POSSIBLE
THERE AT ANY TIME. WILL MONITOR RIVER LEVELS VIA OBSERVER. ICE
SHOULD BEGIN TO BREAK UP SUNDAY NIGHT AS RAIN MOVES IN. RISES ARE
POSSIBLE BY MONDAY AND TUESDAY FROM RAIN AND SNOW MELT.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
