AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
345 PM CDT SAT JUL 29 2006

...PROLONGED PERIOD OF HOT WEATHER EXPECTED ACROSS THE AREA...

.SHORT TERM...TONIGHT AND SUNDAY. COLD FRONT THAT MOVED THROUGH LAST
NIGHT NOW IN SOUTHWEST WISCONSIN. IT SHOULD BE THE FOCUS OF THUNDERSTORM
ACTIVITY TONIGHT AS IT TRIES TO LIFT NORTHEAST AS A WARM FRONT. MOVEMENT
OF THE FRONT IS TRICKY AS THE COOL OUTFLOW WILL BE BATTLING THE
SOUTHERLY GRADIENT. EXPECT IT TO LIFT SLOWLY NORTHEAST TONIGHT AND STALL
ACROSS THE NORTH SUNDAY. THEREFORE WE KEPT THE CHANCE OF THUNDERSTORMS
IN THE FORECAST FOR TONIGHT AND SUNDAY.

.LONG TERM...SUNDAY NIGHT THROUGH NEXT SATURDAY.
SCATTERED THUNDERSTORMS ARE STILL POSSIBLE SUNDAY EVENING AS WARM
FRONT SHIFTS NORTH INTO NORTHERN WISCONSIN. VERY HOT WEATHER IS
EXPECTED MONDAY AND TUESDAY WITH TEMPERATURES APPROACHING 100 DEGREES
AWAY FROM THE LAKE. DEPENDING ON WHAT SURFACE DEWPOINTS ARE ON THESE
TWO DAY...CURRENT THINKING IS THAT THE HEAT INDICIES WILL CLIMB INTO
THE HEAT ADVISORY CRITERIA BOTH AFTERNOONS AND MAY REACH HEAT WARNING
CRITERIA. OUR CRITERIA FOR A HEAT ADVISORY IS FOR HEAT INDICIES OF
105 DEGREES OR HIGHER FOR 3 HOURS...WHILE HEAT WARNING IS HEAT
INDICIES OF 110 DEGREES OR HIGHER OR 3 HOURS.

COLD FRONT IS EXPECTED TO MOVE ACROSS THE AREA TUESDAY NIGHT...BRINGING
MUCH NEEDED RAIN AND COOLER TEMPERATURES ON WEDNESDAY. REMAINDER OF
THE FORECAST IS DRY ALTHOUGH NEED TO WATCH NEXT SATURDAY AS RETURN FLOW
SETS UP.
