AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1202 AM EST SUN FEB 13 2011

LATEST UPDATE...SHORT TERM...

.SYNOPSIS...(310 PM EST SAT FEB 12 2011)
THE NEXT WARM FRONT WILL PUSH THROUGH SOUTHWEST LOWER MICHIGAN
OVERNIGHT AND BE PROCEEDED BY AN AREA OF SNOW.  ONCE THE WARM FRONT
IS THROUGH SUNDAY MORNING CLOUDS... PATCHY DRIZZLE OR FREEZING
DRIZZLE IS POSSIBLE. A SLIGHTLY STRONGER COLD FRONT WILL COME
THROUGH SUNDAY NIGHT WITH MORE SNOW SHOWERS...WHICH WILL CONTINUE
INTO MONDAY. HIGH PRESSURE IS EXPECTED WILL CROSS THE AREA TUESDAY
WITH SOME SUNSHINE. THEN THE STRONGER WARM FRONT WILL COME THROUGH
EARLY WEDNESDAY. AFTER THAT WARM FRONT COMES THROUGH TEMPERATURES
WILL MOSTLY REMAIN ABOVE FREEZING UNTIL THE COLD FRONT WITH SYSTEM
ON FRIDAY COMES THROUGH LATE IN THE DAY. GUSTY SOUTHERLY WINDS
WILL BRING SURGE OF VERY WARM AIR AHEAD OF THE STORM ON FRIDAY. THIS
COULD SEND TEMPERATURES IN THE MID TO UPPER 50S (NOT IN THE OFFICIAL
FORECAST YET). EXPECT SHOWERS FRIDAY AND THUNDERSTORMS ARE NOT OUT
OF THE QUESTION. IT WILL BE WINDY TOO... SO GIVEN THE STRONG
WINDS... DEW POINTS WELL ABOVE FREEZING AND AIR TEMPERATURES PUSHING
50 DEGREES....I WOULD EXPECT CONSIDERABLE SNOW MELT. THAT WOULD
LIKELY RESULT IN SIGNIFICANT FLOOD ISSUES.

&&

.SHORT TERM...(1202 AM EST SUN FEB 13 2011)
(TONIGHT THROUGH MONDAY NIGHT)
THE SNOW IS WINDING DOWN. AS LIFT REMAINS IN THE CLOUD LAYER AND THE
DGZ BECOMES UNSATURATED...THERE MAY BE BRIEF PERIOD OF FZDZ OR
FLURRIS OVERNIGHT. LATEST NAM GUIDANCE SHOWS A BIT LESS IN THE WAY
OF MOISTURE SUNDAY AND FCST SOUNDINGS SUGGEST THAT THERE MAY NOT BE
MUCH MOISTURE TO TRAP BENEATH THE INVERSION. SO IT/S LOOKING MORE
LIKELY THAT WE WILL NOT SEE FZDZ/FLURRIES SUNDAY.

THE COLD FRONT WILL COME THROUGH SUNDAY NIGHT AND THAT WILL LIKELY
RESULT IN MORE SNOW SHOWERS INTO MONDAY MORNING. ACCUMULATIONS
SHOULD BE LIMITED AS TEMPERATURES WILL STRUGGLE TO GET BELOW
FREEZING SUNDAY NIGHT.

SOME CLEARING IS EXPECTED MONDAY NIGHT AND THAT SHOULD ALLOW
TEMPERATURES TO FALL INTO THE TEENS.

STRONG WINDS ARE EXPECTED THROUGH MOST OF THIS TIME PERIOD DUE TO
ANN UNUSUALLY DEEP STORM (PUSHING THE WARM FRONT THROUGH TONIGHT AND
THE COLD FRONT THROUGH SUNDAY NIGHT) CROSS EAST NORTH OF LAKE
SUPERIOR SUNDAY NIGHT. THE RISK OF BLOWING SNOW WILL BE LIMITED
THROUGH AS THE SNOW WILL BECOME WET AS TEMPERATURES WILL MOSTLY BE
ABOVE FREEZING FROM MIDDAY SUNDAY UNTIL MONDAY EVENING. &&

.LONG TERM ...(310 PM EST SAT FEB 12 2011)
(TUESDAY THROUGH SATURDAY)

TEMPS WILL UNDERGO A MODERATING TREND TUESDAY THROUGH FRIDAY IN A
PERSISTENT SW FLOW WAA REGIME. THIS WILL RESULT IN SIGNIFICANT SNOW
MELT AND POTENTIALLY SOME AREAS OF FOG BY LATE THIS WEEK WHEN MAX
TEMPS WILL REACH WELL INTO THE 40S.

A FAIRLY STRONG LOW PRESSURE SYSTEM WILL MOVE THROUGH OUR REGION
LATE FRIDAY BRINGING SOME SHOWERS. A CONSENSUS OF LATEST MEDIUM
RANGE GUIDANCE SUGGESTS THE COLD FRONT WILL COME THROUGH FRIDAY
NIGHT WITH TEMPS RETURNING TO NEAR NORMAL LEVELS FOR NEXT WEEKEND.

&&

.AVIATION...(1131 PM EST SAT FEB 12 2011)
RADAR SHOWS SNOW IS ENDING ACROSS THE REGION AND HAS DIMINISHED TO
FLURRIES IF ANYTHING IN MOST LOCATIONS. TYPICALLY AFTER A WARM FRONT
MOVES THROUGH WE SEE CIGS INCREASE. THAT IS OCCURRING NOW WITH AREAS
SOUTH OF A KBIV TO KJYM LINE VFR. VFR CIGS SHOULD CONTINUE TO MOVE
NORTH OVERNIGHT. I BELIEVE WE/RE GOING TO STAY VFR OVERNIGHT AND
PROBABLY SUNDAY TOO. WINDS WILL SLOWLY INCREASE OVERNIGHT AND SUNDAY
BUT REMAIN SWLY.

&&

.MARINE...(336 PM EST SAT FEB 12 2011)
IT NOW SEEMS GALES ARE A GOOD POSSIBILITY SUNDAY AFTERNOON INTO
MONDAY AFTERNOON AS THAT VERY DEEP CANADIAN STORM TRACKS EAST ALONG
THE CANADIAN BOARDER SUNDAY INTO MONDAY. I ISSUED A GALE WATCH ON
TOP OF THE SCA ALREADY IN PLACE.

&&

.HYDROLOGY...(310 PM EST SAT FEB 12 2011)
OF COURSE THE BIG ISSUE WILL BE LATE THIS COMING WEEK AS THE SURGE
OF HIGH DEW POINT AIR ON STRONG SOUTHERLY WINDS POWER MELTS THE SNOW
ON THE GROUND. WE WILL CONTINUE TO MONITOR THIS BUT A SIGNIFICANT
FLOOD EVENT IS MORE THAN POSSIBLE. ALL DEPENDS ON HOW THIS ALL PLAYS
OUT.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
LM...SMALL CRAFT ADVISORY FOR THE ENTIRE NEAR SHORE THROUGH MONDAY
MORNING.
     GALE WATCH FOR THE ENTIRE NEAR SHORE LATE SUNDAY AFTERNOON INTO
MONDAY AFTERNOON.
