AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
955 PM EST WED FEB 16 2011

LATEST UPDATE...AVIATION...

.SYNOPSIS...(245 PM EST WED FEB 16 2011)
CLOUDS WILL RETURN TONIGHT AS EVEN WARMER AND MORE MOIST AIR MOVES
IN FROM THE SOUTH. EVENTUALLY SOME LIGHT RAIN WILL DEVELOP LATE
TONIGHT. PRECIPITATION CHANCES WILL CONTINUE THURSDAY WITH RECORD
HIGH TEMPERATURES POSSIBLE.

A COLD FRONT WILL THEN MOVE ACROSS THE AREA THURSDAY NIGHT. THIS
WILL BRING THE BEST CHANCE OF RAIN TO THE AREA. COLDER AIR WILL
GRADUALLY FILTER IN FRIDAY AFTERNOON AND FRIDAY NIGHT. THE FORECAST
EARLY NEXT WORK WEEK REMAINS HIGHLY UNCERTAIN...BUT A WINTER STORM
IS NOT OUT OF THE QUESTION.

&&

.SHORT TERM...(245 PM EST WED FEB 16 2011)
(TONIGHT THROUGH FRIDAY)
MAIN FOCUS FOR THIS FORECAST PACKAGE IS TIMING PRECIPITATION THROUGH
THURSDAY NIGHT. A SECONDARY CONCERN IS ADDRESSING THE WARM UP
THROUGH THE REST OF THE WORK WEEK.

WITH 50+ DEWPOINTS ALREADY OBSERVED MOVING INTO SRN IL AND IN...
THERE IS LITTLE DOUBT THAT STRONG MOIST RETURN WILL COMMENCE
TONIGHT. STRONG THETA-E ADVECTION WITH A STRONG LOW-LEVEL JET / 50+
KT AT 925 MB / WILL CONTRIBUTE TO SUFFICIENT DESTABILIZATION FOR R-
/ RW- OVERNIGHT. WE ARE SOMEWHAT CONCERNED ABOUT FOG AROUND SNOWPACK
DUE TO DEWPOINTS CLIMBING INTO THE UPPER 30S OVERNIGHT. HAVE
MENTIONED THIS IN THE FORECAST...BUT BELIEVE STRONG WINDS WILL
MITIGATE THE COVERAGE AND RESTRICTIONS TO VISIBILITY. RAINFALL
AMOUNTS ARE NOT EXPECTED TO BE PARTICULARLY SIGNIFICANT AND SHOULD
OCCUR PRIMARILY AFTER MIDNIGHT.

RAINFALL POTENTIAL WILL CONTINUE THURSDAY AND THURSDAY NIGHT AS THE
UPPER RIDGE AXIS SHIFTS EAST AND RIPPLY SW FLOW ALOFT WILL GIVE
SEVERAL OPPORTUNITIES FOR UPWARD FORCING AND EPISODES OF RAIN.
AS MENTIONED PREVIOUSLY...THE BEST RAIN CHANCES WILL BE THURSDAY
NIGHT AHEAD OF A COLD FRONT THAT IS EXPECTED TO CLEAR THE AREA EARLY
FRIDAY AHEAD OF A MODERATELY STRONG UPPER PV ANOMALY. UPPER DRY
SLOTTING FRIDAY WILL BE ACCOMPANIED BY SOME LOW-LEVEL CLOUDINESS AND
GUSTY CONDITIONS.

RECORD TEMPERATURES LOOK QUITE POSSIBLE THURSDAY WITH CONTINUED LOW
LEVEL THETA-E ADVECTION AHEAD OF THE APPROACHING FRONT. PLEASE SEE
THE CLIMATE SECTION FOR DETAILS ON THE NUMBERS.

&&

.LONG TERM ...(257 PM EST WED FEB 16 2011)
(FRIDAY NIGHT THROUGH WEDNESDAY)
WILL KEEP FRIDAY NIGHT AND SATURDAY DRY AS H8 TEMPS DO NOT APPEAR TO
BE COLD ENOUGH FOR LAKE EFFECT SNOW SHOWERS FRIDAY NIGHT...AND THEN
SURFACE RIDGING BUILDS INTO THE REGION ON SATURDAY.

THINGS BECOME MORE INTERESTING INTO THE FIRST PART OF NEXT WEEK.
THE MODELS CONTINUE TO SHOW A BAROCLINIC ZONE SETTING UP TO OUR
SOUTH.  IF ANYTHING WE APPEAR TO BE A SOMEWHAT MORE INTO THE COLDER
AIR OF THIS SETUP.  THE ISENTROPIC LIFT WOULD FAVOR THE SW CWA
HAVING THE BEST CHANCE FOR PCPN WHILE THE NE CWA MAY BE THE BATTLE
GROUND FOR A DRY NE FLOW LATE SATURDAY NIGHT INTO SUNDAY.

LOWER CONFIDENCE IN THE PERIOD FROM SUNDAY NIGHT THROUGH WEDNESDAY
AS THE MODELS DIVERGE IN THEIR SOLUTIONS.  THE EURO MODEL CONTINUES
TO FILTER COLDER AIR INTO REGION...KEEPING THE BAROCLINC ZONE AND
PCPN FURTHER SOUTH.  THE GFS HAS BEEN SOMEWHAT MORE CONSISTENT WITH
THE A MORE NORTHERN LOOK TO THIS SETUP.  BECAUSE OF THESE
DIFFERENCES...THEIR ARE TIMING AND PATH DIFFERENCES WITH THE
POTENTIAL STORM SUNDAY NIGHT INTO MONDAY NIGHT.  HAVE TRENDED POPS A
BIT LOWER DUE TO THIS UNCERTAINTY.

&&

.AVIATION...(955 PM EST WED FEB 16 2011)
AS THE WARM AND MOIST AIRMASS MOVES OVER THE SNOWPACK...LOW CLOUDS
AND VISIBILITIES WILL REMAIN A CHALLENGE TONIGHT.  SATELLITE IMAGERY
SHOWS AN AREA OF LOW CLOUDS MOVING NORTH THROUGH THE KMKG TO KFFX
REGION.    WHILE THE MOVEMENT SUGGESTS KMKG MAY CLEAR OUT BY 00Z
THIS EVENING...MODEL DATA SUGGESTS FOG AND SUB IFR CONDITIONS COULD
PERSIST OR EVEN EXPAND THROUGH THE REGION.

MY THOUGHTS ARE THAT AS THE HIGHER DEWPOINT AIR ARRIVES FROM
ILLINOIS AND INDIANA...WE WILL SEE INCREASING IFR OVERNIGHT.  I
ADDED IFR TO KAZO AND KBTL FOR THIS REASON.  CLOSER TO THE
LAKE...THICK FOG SHOULD PERSIST AND KMKG WILL BE ON THE EDGE GIVEN
THE SOUTHERLY FLOW.  WINDS WILL VEER TO THE SOUTH SOUTHWEST ON
THURSDAY CREATING RATHER WIDESPREAD IFR OR LOWER CONDITIONS DURING
THE DAY.  AVIATORS WITH FLIGHT PLANS OVERNIGHT OR THU...SHOULD
MONITOR THE LATEST WEATHER.  FLIGHTS HEADING ALONG AND NORTH OF A
KMKG TO KFFX LINE SHOULD BE PREPARED FOR SUB IFR CONDITIONS THROUGH
THE NIGHT.  MONITOR THE IFR PROGRESSION OF ANY LOWER CONDITIONS
MOVING IN FROM ILLINOIS OR INDIANA.

ANOTHER POTENTIAL ISSUE IS A RISK FOR A THUNDERSTORM LATER TONIGHT.
THE ATMOSPHERE DOES BECOME UNSTABLE AFTER 05Z WHEN THE LOW LEVEL JET
ARRIVES.  THIS WOULD RAISE THE RISK FOR A BRIEF THUNDERSTORM.  NOT
CONFIDENT ENOUGH TO ADD THIS TO THE FORECAST AT THIS TIME.

SOUTH SFC WINDS SHOULD INCREASE TO AROUND 12-16 KNOTS AFTER 03Z
TONIGHT...AND THE WINDS AT 2K FEET ARE PROGGED TO REACH 40-50 KNOTS
AFTER 06Z. THEREFORE EXPECT SPEED SHEAR DURING ANY TAKE OFFS AND
LANDINGS LATE TONIGHT.

&&

.MARINE...(245 PM EST WED FEB 16 2011)
SOUTH WINDS ARE EXPECTED TO INCREASE SUBSTANTIALLY OVERNIGHT.
HOWEVER...THE STABLE PROFILE OF WARM AIR OVER COLD WATER WILL
GREATLY LIMIT DOWNWARD MOMENTUM TRANSFER AND SUBSEQUENT WAVE GROWTH.
EXPECT A SCA WILL BE REQUIRED EARLY IN THE DAY THURSDAY GENERALLY
NORTH OF SOUTH HAVEN. WILL DEFER THE COVERAGE AND TIMING OF THIS
LIKELY HEADLINE TO THE EVENING SHIFT.

&&

.HYDROLOGY...(413 AM EST WED FEB 16 2011)
THE MAIN HYDROLOGY FOCUS REMAINS ON THE UPCOMING SNOW MELT AND RUN
OFF EXPECTED OVER THE NEXT COUPLE OF DAYS WITH THE WARM UP. AS HAS
BEEN MENTIONED...MOST OF THE CWFA/HSA HAS BETWEEN 2 AND 4 INCHES OF
WATER EQUIVALENT IN THE SNOW PACK. AMOUNTS ARE A BIT LOWER ACROSS SE
AREAS. MOST OF THIS SHOULD MELT OFF BETWEEN NOW AND FRIDAY EVENING
WITH DEW POINTS EXPECTED TO EVENTUALLY CLIMB INTO THE 40S AND TEMPS
IN THE 50S...NOT TO MENTION TEMPS STAYING ABOVE FREEZING AT NIGHT
TONIGHT AND THU NIGHT. IT APPEARS AT THIS TIME THAT WE WILL NOT SEE
FLOODING...ALTHOUGH SIGNIFICANT RISES WILL BE LIKELY. THE LACK OF
SIGNIFICANT RAINFALL EXPECTED WILL LIMIT THE RISES A BIT WITH ONLY A
QUARTER OF AN INCH OF RAIN EXPECTED.

ICE ON THE RIVERS WILL ALSO TAKE A BIG HIT WITH THE WARM UP. WE WILL
HAVE TO MONITOR FOR BREAK UP ICE JAMS.

&&

.CLIMATE...(658 AM EST WED FEB 16 2011)
RECORD HIGHS ARE WITHIN REACH THURSDAY (2/17)...
GRR RECORD IS 55 SET IN 1911
LAN RECORD IS 56 SET IN 1880
