Area forecast discussion, May 13, 3:58 PM EDT, 1 hour 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
358 PM EDT FRI MAY 13 2005

.SHORT TERM...

THE MAIN ISSUES FOR THIS FORECAST PACKAGE IS THE EVOLUTION OF THE
ON GOING SEVERE WEATHER EVENT OVER OUR CENTRAL AND SOUTHERN CWA THIS
EVENING. THEN OUR ATTENTION TURNS TO THE NORTHERN STREAM UPPER LOW
THAT MOVES THROUGH THE GREAT LAKES SATURDAY AND SUNDAY. IN GENERAL
THE MODELS ARE RATHER SIMILAR ON HOW THIS ALL PLAYS OUT.

TONIGHT...THE SURFACE LOW PRESSURE SYSTEM INDUCED BY AN MCV FROM
YESTERDAYS CONVECTION WILL TRACK SOUTH OF INTERSTATE 96 THIS
EVENING. SURFACE BASED CONVECTION WITH CAPES NEAR 1500 J/KG AND
COMBINED WITH STRONG SURFACE CONVERGENCE AND DECENT SURFACE
FRONTOGENETICAL FORCING...AIDED BY 35 TO 40 KNOT LOW LEVEL JET AND
50 KNOT MID LEVEL JET SHOULD KEEP THE STORM GOING AHEAD OF THE WAVE
AND KEEP THE POTENTIAL FOR SEVERE STORMS INTO THE EVENING. THE 50
KNOTS OF DEEP LAYER SHEAR SHOULD ALLOW THE STORMS TO ROTATE. WET
BULB ZERO HEIGHTS ARE BELOW 11000 FT AND EQ LEVELS NEAR 30000 FT.
ISOLATED TORNADOES STILL POSSIBLE NEAR THE WARM FRONT SINCE MOST OF
THE HELICITY IS IN THE BOTTOM 1 KM IN NEAR THE WARM FRONT. AREAS
NEAR AND NORTH OF INTERSTATE 96 WILL BE TO DEEP IN THE COLD AIR TO
GET SEVERE THUNDERSTORMS.  NOTE THE MSAS CHARTS INDICATE A MORE EAST
THAN NORTHEAST MOVEMENT ON THE SURFACE LOW WITH THE BEST PRESSURE
FALLS BETWEEN I-94 AND I-80.

LIGHT WINDS BEHIND THE SURFACE WAVE...WHILE WE WAIT FOR THE UPPER
LEVEL SYSTEM OVER MN TO MOVE CLOSE ENOUGH TO THE SURFACE FRONT TO
DEVELOP ANOTHER SURFACE LOW...THAT WILL BECOME THE MAIN SURFACE
SYSTEM WITH TIME. THAT WILL MEAN...AFTER ALL THE RAIN THAT FELL
ACROSS MOST OF THE CWA TODAY... FOG IS EXPECTED OVER NIGHT. THE
COOLER AIR MIXING IN THE WARM AIR NOW IN PLACE THANKS TO THAT
SURFACE LOW PASSING SOUTH OF INTERSTATE 96 WILL HELP THAT CAUSE TOO.

FOR SATURDAY THROUGH SUNDAY THE UPPER LEVEL SYSTEM FROM THE NORTHERN
STREAM MOVES OVER LOWER MICHIGAN. SCATTERED INSTABILITY SHOWERS WILL
BE SEEN OVER THE ENTIRE AREA FROM TIME TO TIME.  I SUSPECT THE GFS
SUFFERED FROM CONVECTIVE FEEDBACK AND I DO NOT EXPECT THE RAIN WITH
SECOND WAVE TO GET TO FAR NORTH INTO GRRS CWA.  STILL JUST IN CASE
I GAVE OUR SOUTHERN ROW OF COUNTIES LIKELY POPS SATURDAY MORNING TO
ALLOW FOR THAT WAVE TO MOVE BY.   SATURDAY NIGHT... IT MAY JUST GET
COLD ENOUGH (1000/850 MB THICKNESS GET NEAR 1300 M) OVER OUR NRN CWA
AND FREEZING LEVELS DOWN TO NEAR 2000 FT. THAT WOULD MEAN OUR
HIGHER ELEVATIONS WILL HAVE A CHANCE OF MIXED RAIN AND SNOW LATE
SATURDAY NIGHT INTO EARLY SUNDAY MORNING.

TEMPERATURES ARE CLOSE TO BUT MOSTLY BELOW MOS FORECASTS BASED ON
OUR BEING UNDER THE UPPER TROUGH AND SKIES BEING CLOUDY MOST OF THE
WEEKEND.

.LONG TERM...
LOOKS LIKE A SLOW DOWN IN THE EASTWARD PROGRESSION OF THE 500MB
TROUGH LATE IN THE WEEKEND INTO EARLY NEXT WEEK. STRONG CUTOFF LOW
REMAINS IN PLACE ACROSS THE COAST OF LABRADOR...WITH A WEDGE OF
RIDGING IN THE NORTH ATLANTIC. THIS WOULD HELP TO SLOW THE EASTWARD
MOVEMENT...AND MOST LIKELY HELP TO BUILD THE RIDGING THROUGH THE
INTERIOR WEST STRETCHING INTO THE CANADIAN ROCKIES. COOL TEMPS WILL
STICK WITH US THROUGH MONDAY...AND INTO MUCH OF NEXT WEEK. FLOW WILL
BECOME WEST TO EAST...WITH A BROAD AREA OF HIGH PRESSURE BUILDING
ACROSS THE FOUR CORNERS OF THE U.S. STRETCHING THROUGH THE
PLAINS...AND OHIO RIVER VALLEY. THIS WILL HELP TO KEEP DRY
CONDITIONS THROUGH MUCH OF NEXT WEEK. HIGHS WILL MAINLY BE IN THE
60S...IT WILL BE POSSIBLE MID TO LATE WEEK FOR TEMPS APPROACHING 70
TO THE LOW 70S IN EXTREME SOUTHERN LOWER MICHIGAN. OVERALL BELOW
NORMAL TEMPS WITH DRY CONDITIONS.

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

.DAY ONE...THIS AFTERNOON AND TONIGHT

SEVERE THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON AND EARLY EVENING
SOUTH AND EAST 10 MILES NORTH OF HOLLAND TO NEAR ST JOHNS.  THE MOST
LIKELY TIME FOR THIS THREAT IS BETWEEN 3 PM AND 10 PM TONIGHT. WIND
GUSTS TO 70 MPH...HAIL TO 2 INCHES IN DIAMETER AND ISOLATED
TORNADOES ARE THE MOSTLY LIKELY THREATS.  THE ISOLATED
TORNADOES ARE POSSIBLE NEAR THE WARM FRONT DURING THE LATE AFTERNOON
INTO THE EARLY EVENING. THAT SHOULD MOSTLY BE SOUTH AND EAST OF
LANSING. HEAVY RAINFALL...WITH RAINFALL RATES OVER 1 INCH AN HOUR IS
ALSO POSSIBLE WITH THESE THUNDERSTORMS. FREQUENT CLOUD TO GROUND
LIGHTNING IS ALSO EXPECTED WITH THOSE THUNDERSTORMS. ISOLATED NONE
SEVERE THUNDERSTORMS... WITH THE THREAT OF HEAVY RAINFALL ARE
POSSIBLE ACROSS THE REST OF THE AREA.

A LOW PRESSURE SYSTEM SYSTEM NEAR CHICAGO AT 2 PM THIS AFTERNOON
WILL MOVE EAST NORTHEAST TOWARD THE DETROIT AREA BY EARLY THIS
EVENING. THAT WILL BRING THE WARM FRONT TO NEAR LANSING BY LATE THIS
AFTERNOON. IT IS NORTHWARD PUSH OF AIR WITH THE WARM FRONT THAT WILL
HELP TO FOCUS THE SEVERE WEATHER THREAT SOUTH AND EAST OF LANSING
LATE THIS AFTERNOON AND EVENING.

OVERNIGHT...ONCE THAT ALL MOVES OUT... WINDS WILL BECOME LIGHT. WITH
ALL THE RAIN THAT FELL DURING THE DAY TODAY... AREAS OF DENSE FOG
MAY DEVELOP AFTER MIDNIGHT.
