Area forecast discussion, Jun 10, 2:22 PM EST, 6 hours 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
222 PM EST THU JUN 10 2004

.DISCUSSION...FCST FOCUS REMAINS ON PRECIP CHCS IN ATMOSPHERE
CHARACTERIZED BY NEARLY SATURATED ATMOSPHERE IN SUB-TROPICAL
MOISTURE PLUME. WEAK STATIONARY BOUNDARY WILL ALSO REMAIN IN THE
VICINITY AND WEAK WAVES WILL MOVE THROUGH UPPER RIDGE NEXT 24 HOURS.

WILL LEAN TOWARD A BLEND OF ETA/GFS AS BOTH ARE HANDLING ONGOING
AREA OF PRECIP ACROSS IL FAIRLY WELL.  PROFILERS SUGGEST THIS PRECIP
IS DEVELOPING ON NOSE OF 30-40KT LLJ/STRONGEST WAA. REMAINDER OF
REGION IS ALSO SEEING SCT SHWRS DEVELOPING WITHIN GENERAL 850-700MB
WAA REGIME.  LATEST RADAR TRENDS ALONG WITH POSITION OF FRONT
SUGGEST THAT HIGHEST PRECIP CHCS SHOULD REMAIN ACROSS THE NORTHERN
HALF OF THE CWA TODAY. AS FOR SVR THREAT...0-6KM SHEAR WILL BE
MARGINAL (20-25KTS) ACROSS THE CWA TODAY. ONLY AREA OF CONCERN WOULD
BE JUST N-NW OF CWA (ACROSS IL) ALONG/NORTH OF WARM FRONT WHERE
SHEAR WILL BE HIGHER SUGGESTING POTENTIAL FOR ORGANIZED STORMS. AS
FOR INSTABILITY, ETA SOUNDINGS SUGGEST CONVECTIVE TEMPS AROUND 85F.
IF TEMPS REACH THIS...POSSIBLE SOUTH OF I-70...IT WOULD APPEAR THERE
WILL BE 1000-1500 CAPE...AT THIS POINT IT APPEARS THAT MID CLDS MAY
INHIBIT GREATER INSTABILITY. IN A NUTSHELL, SVR CHCS APPEAR MINIMAL
AT LEAST LOOKING AT THINGS RIGHT NOW.

FOR TONIGHT...WILL KEEP 40-60 POPS ACROSS THE CWA AS NOSE OF
30-40KT LLJ IS LOCATED ACROSS CENTRAL IL. STRONGEST WAA WILL BE
NORTH OF THE CWA BUT ANY PRECIP THAT DEVELOPS ACROSS IL WOULD TRACK
ENE ACROSS MY CWA. UPPER WAVE RESPONSIBLE FOR ENHANCING WAA/PRECIP
CHCS TODAY/TONIGHT WILL WEAKEN AND MOVE EAST BY FRI. BY FRI,
DYNAMICS ASSOCIATED WITH MAJOR TROUGH SHOULD KEEP GREATER THREAT FOR
ORGANIZED/SVR STORMS NW OF THE AREA...WHILE IN REMAINS UNDER UPPER
RIDGE. WARM FRONT SHOULD LIFT NE OF THE CWA TAKING THE HIGHER PRECIP
CHCS WITH IT. CURRENT PRECIP FCST LOOKS GOOD WITH LOWER CHCS FRI
NIGHT-SAT NIGHT. BETTER CHCS WILL THEN DEVELOP LATER SUN-MON AS
RIDGE FLATTENS AND WESTERLIES MIGRATE INTO THE REGION. SHORTWAVE
DISTURBANCES ARE THEN FCST TO RACE THROUGH THE FLOW WHICH ALONG WITH
THE APPROACHING FRONT SHOULD SET THE STAGE FOR THUNDERSTORMS
SUN-MON. NO CHANGES TO THE EXTENDED WITH DRY CONDS AFTER MON.
