England.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 730 PM EDT...latest radar showing an organized line of
showers and thunderstorms across the Greater Capital District
into southern Vermont. Areas south of Albany into southern New
England could see some periods of heavy rain this evening before
diminishing after 9-10 pm. The radar is showing some training

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/...
The main threat of showers and thunderstorms should diminish
after 9PM tonight. Some additional showers and possibly an
isolated thunderstorm may linger until the passage of the short
wave trough. It will be humid with dewpoints in the upper 60s to
lower 70s. Will include fog late tonight with low level
moisture and calm wind.

Sunday...The humidity will be on the increase and will have a
repeat of afternoon showers and thunderstorms with an area of
low pressure along a boundary. With instability, lift and
moisture there will be the threat of severe thunderstorms. Main
threats will be gusty winds and heavy downpours. Some flash
flooding will be possible. Temperatures on Sunday will be a few
degrees warmer with highs in the mid to upper 80s.

Sunday night...Any showers and thunderstorms that develop will
diminish with the loss of heating and as the boundary continues

degrees.

degrees at most locations across the mid Hudson Valley, The
Greater Capital Region and the Lake George Saratoga region. It
will be very humid and oppressive with dewpoints in the lower
