AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
724 AM EDT THU APR 5 2012
.SYNOPSIS...
ISSUED AT 400 AM EDT THU APR 5 2012
FAIR WEATHER WILL CONTINUE THROUGH SATURDAY AFTERNOON WITH HIGH
PRESSURE IN CONTROL. IT WILL BE QUITE COLD TONIGHT WITH A WIDESPREAD
FREEZE ANTICIPATED AND POTENTIAL FOR MORE FROST AND FREEZING
CONDITIONS AGAIN FRIDAY NIGHT. A LOW PRESSURE SYSTEM WILL BRING A
CHANCE OF SHOWERS SATURDAY NIGHT. IT WILL BE VERY COOL EARLY NEXT
WEEK.
&&
.SHORT TERM...(TODAY THROUGH FRIDAY AFTERNOON)
ISSUED AT 400 AM EDT THU APR 5 2012
00Z NAM/GFS TIME HEIGHT RH PROGS SUGGEST SKIES WILL BE MOSTLY SUNNY
TODAY AFTER LINGERING HIGH CLOUDS DEPART OUR FAR SOUTHERN FCST AREA
LATER THIS MORNING. IT WILL BE COOLER WITH MAX TEMPS ONLY REACHING
THE LOW TO MID 50S AFTER A COOL START TO THE DAY.
TEMPS CONTINUE TO FALL SLOWLY EARLY THIS MORNING WITH A FEW UPPER
20S READINGS OVER OUR NORTHERN FCST AREA AND DOWN INTO THE MID 30S
CENTRAL AND EAST. AS MENTIONED YESTERDAY EVENING THIS WILL LIKELY
END UP BEING A RATHER MARGINAL FROST/FREEZE EVENT... BUT WITH
SEVERAL HOURS OF COOLING STILL TO GO DECIDED TO LEAVE OUR CURRENT
FROST/FREEZE HEADLINES UNCHANGED.
IT SHOULD BE STRESSED THOUGH THAT CONDITIONS CONTINUE TO APPEAR MORE
FAVORABLE FOR A WIDESPREAD FREEZE TONIGHT AS HIGH PRESSURE CONTINUES
TO BUILD SOUTH OVER MI SETTING UP EXCELLENT RADIATIONAL COOLING
CONDITIONS UNDER CLEAR SKIES/WINDS GOING CALM BY LATE EVE. AFTER
CLEARING OUR MORNING HEADLINES WHICH EXPIRE AT 13Z WE ANTICIPATE THE
DAY SHIFT WILL BE ABLE TO HOIST THE APPROPRIATE HEADLINES TO COVER
THE FREEZE EVENT FOR TONIGHT LATER TODAY RATHER THAN GOING WITH
MULTIPLE HEADLINES EARLY THIS MORNING.
MOSTLY SUNNY SKIES ON TAP FOR THURSDAY WITH MAX TEMPS REACHING THE
MID TO UPPER 50S WITH FULL SUN AFTER THE COLD START TO THE DAY.
.LONG TERM...(SATURDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 400 AM EDT THU APR 5 2012
STILL LOOKS LIKELY FOR FREEZING TEMPERATURES FRIDAY NIGHT. THEN
THERE IS THE ISSUE WITH THE CONVECTION WITH THE OCCLUDED FRONT EARLY
SUNDAY MORNING. FINALLY THERE IS THE SIGNIFICANT COLD PUSH EARLY
NEXT WEEK... I COULD STILL SEE SOME MIXED RAIN AND SNOW SHOWERS WITH
THAT.
MODEL AGREEMENT IS BETTER THAN USUAL WHICH LEADS TO A HIGH CONFIDENT
FORECAST FOR THIS PERIOD. THE BLOCKING UPPER HIGH THAT WAS PARKED
BETWEEN GREENLAND AND GREAT BRITAIN FOR MUCH OF THE COLD SEASON
CONTINUES TO SHOW SIGNS OF RETROGRESSION TOWARDS ATLANTIC...JUST OFF
SHORE OF CANADA BY MID NEXT WEEK. THAT RESULTS IN RETROGRESSION OF
THE LONG WAVE TROUGH THAT HAS BEEN OFF THE EAST COAST INTO THE
EASTERN HALF OF THE UNITED STATES EARLY NEXT WEEK. THIS WILL RESULT
IN A CONTINUED COOLING TREND IN THE OVERALL TEMPERATURES.
BY MONDAY AND TUESDAY OF NEXT WEEK THE POLAR JET STREAM ACTUALLY IS
SOUTH OF I-80... WHICH PUTS SOUTHWEST MICHIGAN IN GREAT PLACE FOR
COLD CORE INSTABILITY SHOWERS MONDAY AND TUESDAY. THE INSTABILITY
INDEX VALUES SHOW MORE UNSTABLE MONDAY AFTERNOON THEN EARLY SUNDAY
MORNING WITH THE OCCLUDED FRONT. ANOTHER SHORTWAVE DIVING INTO THE
LONG WAVE TROUGH COULD RESULT IN SHOWERS WEDNESDAY TOO (NOT PUT IN
GRIDS JUST YET). IF ANY THING THE COOLING THIS WILL CAUSE IS LIKELY
UNDER FORECAST. THIS IS MORE IN TERMS OF AFTERNOON HIGHS THEN
OVERNIGHT LOWS AS THERE WILL BE CONSIDERABLE CLOUDS AROUND THROUGH
THIS PERIOD). AS I WROTE YESTERDAY IF THE PATTERN TURNS OUT THIS WAY
I WOULD HAVE LIKELY POP MON... TUE AND POSSIBLY WEDNESDAY FOR
SHOWERS. THE PRIMARY REASON FOR ONLY CHANCE POPS NOW THEN IS EVENT
IS FAR OUT IN TIME YET AND THIS IS A SIGNIFICANT PATTERN CHANGE. I
ALSO BELIEVE THE MODELS ARE UNDER FORECASTING THIS EVENT. I DO
EXPECT TO SEE SOME SNOW SHOWERS FROM THIS PATTERN EARLY NEXT WEEK.
WITH TIME WE WILL FINE TUNE THIS ASPECT OF THE FORECAST.
AS FOR THE FREEZE SATURDAY MORNING... WITH THE SURFACE HIGH IS
OVERHEAD THEN SO WINDS WILL BE LIGHT AND VARIABLE THROUGH THE
BOUNDARY LAYER. THAT WILL LET TEMPERATURES PLUNGE. I WENT BELOW MOS
SATURDAY MORNING FOR THAT REASON.
THE CONVECTION WITH THE OCCLUDED FRONT (JET CORE IS SOUTH OF CHI SO
FRONT IS OCCLUDED) THAT COMES THROUGH AROUND MIDNIGHT SUNDAY SHOULD
BE UNIMPRESSIVE AT BEST. THERE IS A SIGNIFICANT LACK OF INSTABILITY
(TQ INDEX LESS THAN 15C AND 850 LI MORE THEN +5C) WITH THE FRONT.
EVEN THE 1000 TO 850 MB MOISTURE TRANSPORT VECTORS ARE UNIMPRESSIVE.
THE LATEST SPC SREF THUNDERSTORM PROBABILITY IS NEAR ZERO TOO. FOR
ALL THOSE REASONS I DROPPED THE THREAT OF THUNDERSTORMS EARLY SUNDAY
MORNING. EVEN SO THERE IS DECENT DYNAMICS AND THERE IS A NARROW
PLUM OF PERCEPTIBLE WATER NEAR 300 PCT OF NORMAL SO THERE SHOULD BE
BRIEF PERIOD OF SHOWERS WITH THE FRONT.
&&
.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)
ISSUED AT 725 EDT THU APR 5 2012
AN AREA OF LOW CLOUDS (MVFR CIGS) OVER LAKE HURON HAS MOVED SE
INTO CENTRAL LOWER MICHIGAN. THIS AREA OF LOW CLOUDS SHOULD MIX
OUT BY MID LATE MORNING BUT IT LIKELY WILL BRING A PERIOD OF MVFR
CIGS TO LAN AND POSSIBLY GRR UNTIL AROUND 15Z OR SO. AFTER THAT
NEARLY CLEAR SKIES SHOULD PREVAIL INTO SATURDAY MORNING.
&&
.MARINE...
ISSUED AT 400 AM EDT THU APR 5 2012
MINIMAL WIND/WAVE ACTION ANTICIPATED THROUGH FRIDAY AS HIGH PRESSURE
BUILDS SOUTH. THE NE WIND COMPONENT TODAY WILL KEEP WAVE HEIGHTS IN
CHECK.
