AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
312 AM CDT TUE JUN 24 1997

THUNDERSTORMS ARE THE MAIN CONCERN FOR TODAY.

06Z SURFACE MAP SHOWED A LOW ALONG THE ND/MN BORDER WITH A WARM FRONT
ACROSS MN...NW WI AND NORTHERN UPPER MI A COLD FRONT ALSO EXTENDED SW
FROM THE LOW TO SW SD. PLENTY OF M60S/L70S DEW POINTS SHOWING UP ACROSS
THE CWA. COMPOSITE RADAR INDICATED SHOWERS/THUNDERSTORMS FROM NC MI TO
NC SD AND IN IOWA. 00Z SOUNDINGS SHOWED PLENTY OF INSTABILITY ACROSS THE
REGION BUT THERE IS ALSO A CAP.

GOES-8 WV IMAGES HAVE VORT VICINITY OF KS/NEBRASKA BORDER AT 06Z WHICH
IS CLOSE TO 06Z AVN POSITION OFF NTRANS. NO U/A DATA INTO ETA/NGM
SO WILL LEAN TOWARD AVN FOR FORECAST TODAY. ETA/NGM/AVN ALL SHOWED QPF
OVER SOME/ALL OF THE CWA BY 12Z. AVN TAKES SURFACE LOW TO NE MN BY 00Z
WED WITH COLD FRONT NEAR WI/MN BORDER AND TAKES VORT MAX TO AROUND
KMDZ BY THAT TIME. MEAN RH PROGGED TO BE 70+ PERCENT ACROSS THE CWA AT
00Z WED WITH 2+ MICROBARS/SEC OF LIFT OVER MOST OF THE AREA.

THUNDERSTORMS MORE LIKELY WITH APPROACH OF THE SHORT WAVE AND COLD FRONT
LATER TODAY...BUT SOMETHING MAY FORM BEFORE THAT ALONG ANY BOUNDARIES
PRODUCED BY OVERNIGHT CONVECTION. FWC TEMPS2 ARE LOOKING GOOD SO FAR. FAN
SEEMS A BIT LOW...BASED ON CURRENT TEMPS AND WARM AIRMASS...SO WILL USE
FWC. POPS ARE SIMILAR ON BOTH AT KGRB. FEW ADJUSTMENTS NEEDED TO CURRENT
FORECAST.
