AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
254 PM EDT MON JUL 13 2009

.SYNOPSIS...
AN UPPER LEVEL TROUGH WILL ALLOW FOR A CHANCE OF A SHOWER OR
THUNDERSTORM ON TUESDAY. A WEAK SURFACE RIDGE WILL ALLOW FOR DRY
CONDITIONS TUESDAY NIGHT THROUGH WEDNESDAY NIGHT. A STRONG UPPER
LEVEL TROUGH WILL SLOWLY APPROACH THE NORTHEAST LATE IN THE WEEK
AND OVER THE WEEKEND...BRINGING UNSETTLED WEATHER TO THE REGION.

&&

.NEAR TERM /THROUGH TONIGHT/...
SHORT WAVE ROTATING AROUND BASE OF UPPER LOW WHICH IS FIRING UP
CONVECTION OVER NORTHERN AND MOUNTAIN SECTIONS OF THE FORECAST
AREA AT THIS TIME. NO SEVERE AS OF YET AS IT APPEARS WERE HAVING

MODEL TO MODEL IN THE EXTENDED FORECAST.

PLAYED IT DRY TUESDAY NIGHT AND WEDNESDAY AS FLAT
RIDGE RACES ACROSS THE NORTHEAST...INBETWEEN WEATHER SYSTEMS. WARM
AIR ADVECTION POTENT ENOUGH OVER SOUTHERN NEW ENGLAND TO RIDES
SCATTERED SHOWERS AND THUNDERSTORMS INTO MAINE AND NEW HAMPSHIRE
BY WEDNESDAY NIGHT. THEREAFTER...ONCE LONG WAVE UPPER LEVEL TROUGH
PROGRESSES FAR ENOUGH TO THE EAST...MAINE/NEW HAMPSHIRE CAN EXPECT
SEVERAL DAYS WITH MOSTLY DIURNALLY DRIVEN SCATTERED SHOWERS AND
