Severe Thunderstorm Warning 84, NWS Northern Indiana

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
300 PM EST SUN JUN 29 2003

FORECAST DISCUSSION FOR TODAY THROUGH WEDNESDAY...

EARLIER A FEW STORMS FIRED UP IN OUR MICHIGAN COUNTIES AND MOVED
EASTWARD BUT DIDNT AMOUNT TO MUCH. SOME STORMS HAVE FIRED UP IN
ELKHART AND LAGRANGE COUNTIES AND THERE ARE SOME STRONGER ONES DOWN
IN THE CENTRAL PART OF THE STATE. BECAUSE OF ALL THIS THREW IN A
CHANCE FOR THE EARLY EVENING HOURS IN OUR EASTERN PART. INDICIES
SHOWING SOME INSTABILITY BUT NOTHING IS TOO GREAT. FRONT IS JUST TO
OUR NORTHWEST AND SOME BOUNDARIES SETTING UP IN THE ZONAL FLOW.
FRONT SHOULD THEN SAG FAR ENOUGH SOUTHWARD TO LEAVE TONIGHT DRY.
THEN DEPENDING ON THE POSITIONING OF THE FRONT TOMORROW COULD HAVE
SOME STORMS THROUGH OUR VERY SOUTHERN COUNTIES. THIS MATCHES UP WITH
OUR SOUTHERN NEIGHBORS. TUESDAY NIGHT THROUGH WEDNESDAY SHOULD THEN
BE DRY AS THAT FRONT IS THEN FAR ENOUGH SOUTH AND HIGH PRESSURE WILL
BE OVER OUR CWA. TEMPERATURES FROM PREVIOUS FORECAST LOOKED TO STILL
BE ON TRACK.

FORECAST DISCUSSION FOR WEDNESDAY NIGHT THROUGH SUNDAY...

FEW CHANGES TO EXTENDED GRIDS THIS PACKAGE. CHANCES FOR
PRECIPITATION LATE THIS WEEK AND INTO WEEKEND WILL DEPEND ON
LOCATION OF QUASISTATIONARY BOUNDARY AND GULF MOISTURE. GFS
CONTINUES TO SHOW SOME TYPE OF MCS NORTH OF FRONT CROSSING THE GREAT
LAKES. CANNOT BE SURE IF THIS IS CONVECTIVE FEEDBACK OR NOT. EVEN IF
NOT...MODELS STILL INDICATE WEEK FRONT CROSSING AREA FRI AND HANGING
UP NEAR OR JUST TO SOUTH. ALSO OF INTEREST WILL BE MOISTURE COMING
NORTH OUT OF GULF OF MEXICO AND ITS MOVEMENT AND INTERACTION WITH
FRONT. TOO EARLY TO TRY AND PINPOINT ALL THIS SO WL CONTINUE CURRENT
FORECAST. TRENDED TOWARD HPC GRAPHICS/FORECAST FOR MOST OF EXTENDED
WHICH IS IN LINE WITH GOING FORECAST.
