AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1124 AM EDT MON JUL 4 2005

.UPDATE...
SFC ANALYSIS THIS MORNING SHOWS THE FRONTAL SYSTEM THAT HAS BEEN
ADVERTISED FOR THE PAST FEW DAYS CURRENTLY LIES ACROSS THE CENTRAL
SECTIONS OF THE U.P. OF MICHIGAN AND WISCONSIN. RADAR IMAGERY THIS
MORNING SHOWS NUMEROUS SHOWERS AND THUNDERSTORMS AHEAD OF THE SFC
FRONT IN A LINE OVER NRN LOWER MI...THE NE HALF OF THE GRR
CWFA...AND OVER A GOOD PORTION OF LAKE MICHIGAN. SO FAR ALMOST ALL
OF THESE STORMS HAVE BEEN REMAINING UNDER SEVERE LIMITS WITH THE
EXCEPTION OF A BETTER ORGANIZED STORM OFFSHORE NORTH OF KMKE AS OF
11 AM. WITH PLENTY OF CLOUD COVER IN PLACE OVER THE NE HALF OF THE
CWFA...THE ATMOSPHERE IS NOT HAVING A CHC TO REALLY DESTABILIZE AT
THE SFC. THIS SHOULD LIMIT THE SEVERE THREAT QUITE A BIT THERE. DEEP
LAYER SHEAR ON THE ORDER OF AROUND 25 TO AS MUCH AS 35 KTS COULD
ALLOW ISOLATED STORMS TO BECOME ORGANIZED.

THE SE SECTION OF THE CWFA IS A DIFFERENT STORY WITH A DECENT AMOUNT
OF SUN WORKING ON DESTABILIZING THE ATMOSPHERE. TEMPS HAVE ALREADY
HIT 80 IN A FEW PLACES WITH DEW POINTS IN THE LOW TO MID 60S. AS THE
FRONT MOVES EAST AND WITH DIFFERENTIAL HEATING BOUNDARIES PRESENT AS
A RESULT OF THE CLOUD COVER...SCATTERED SHOWERS AND THUNDERSTORMS
WILL BECOME POSSIBLE THERE. ANY THUNDERSTORMS THAT DO DEVELOP OVER
THE SE SECTION OF THE CWFA WILL HAVE THE POTENTIAL OF BECOMING
ORGANIZED AND SEVERE WITH THE BETTER SFC BASED INSTABILITY AND WITH
THE 30 KTS OF DEEP LAYER SHEAR IN PLACE.

PER RADAR TRENDS...HAVE BUMPED POPS UP TO CATEGORICAL OVER THE NW
CORNER OF THE CWFA...AND RAISED POPS TO NUMEROUS FOR THE SW AND NE
CORNERS. HAVE LEFT THE SCATTERED WORDING FOR THE SE...AND MENTIONED
LATER AFTERNOON WORDING. I ALSO DROPPED TEMPS WHERE THE CLOUDS AND
PCPN ARE AND WILL CONTINUE TO HOLD DOWN TEMPS. TEMPS WILL LIKELY NOT
GET OUT OF THE LOWER TO MID 70S OVER THE NW...WHERE SE SECTIONS OF
THE CWFA COULD FLIRT WITH 90 WITH THE SUNSHINE.

.GRR WATCHES/WARNINGS/ADVISORIES...NONE
