.DISCUSSION...

Below normal temperatures with periodic chances of
showers/t-storms will be the theme into next week with a low
pressure system centered over central Canada providing cyclonic
flow into the Great Lakes region. This will continue to allow
for the synoptic cooling and weak disturbances to push eastward
into the area along with surface dew points remaining mainly in
the mid 50s to low 60s, which will keep low temperatures in the
same range over the next several days. A few remaining
sprinkles possible this evening with low clouds in place in the
wake of yesterday`s system but will start to give away to some
clearing with drier mid level flow from the north.

The next chances of showers arrives on Saturday with a weak
shortwave but the better chances for a more widespread and
hearty rainfall will begin on Sunday and continue into Monday
as a stronger shortwave pushes eastward through the cyclonic
flow aloft. A few rumbles of thunder will be possible mainly for
the southern half of the CWA with a bit better instability
further south and PWATs around 1.7 inches making for any
convective showers/storms fairly efficient. WPC currently has
precipitation amounts of 1 to 2 inches over our CWA for Sunday
into Monday. A break in precipitation will return Tuesday but
looks like another disturbance pushes into the region on
Wednesday with another shot of showers/storms.
