Just one bad day. Two out of three ain’t bad.
Guidance is slowly coming into better agreement on the weather for
the upcoming holiday weekend. While we continue to forecast a cooler
than normal weekend with wet weather, the full three day weekend
shouldn`t be a washout. As it stands now, surface high pressure will
be fighting to keep low pressure from the OH valley and its
associated wet weather at bay as long as possible; this means the
earlier in the day on Saturday the better chance we stay dry, it
could even hold out for a fully dry Saturday, especially toward
northeast/north central MA. Eventually the shortwave and wet weather
move over SNE Saturday night/Sunday and this looks to be the most
likely "washout" day before the low moves east of MA by Monday with
drier air funneling in and making for a more pleasant day than
Sunday. Sunday will also be breezy as a 25-35kt LLJ moves overhead.
Temperatures bottom out on Sunday with highs in the upper 50s,
warming into the upper 60s and 70s by Monday.
