.DISCUSSION...

Current confidence is that showers and thunderstorms will remain
north of the forecast location, as ongoing storms northeast of
Glennie track east over Harrisville by 1800/600pm. Current south-
southwest 20 ft winds around 10-15 mph with gusts between 20-30 mph
will switch to west-northwest winds of similar speeds when a cold
front moves through the area around 1930-2000/730-800pm, gradually
turning direction until that time. Current temperatures in the low
90s will cool into the 70s behind the front, along with current RHs
in the mid/upper 30s rising back into the 40-60 percent range. Winds
will quickly decrease through the evening.
