The forecast may not say it, but there is a chance of a stray shower early tonight as well. A small area of showers not associated with Danny has been trying to work its way into Southern New England and could impact set-up in some way.
Danny is no more organized this morning. In fact he has weakened even more to just barely a tropical storm. However, his movement has increased and models are agreeing he'll be influencing our weather during the day tomorrow. Danny will interact with an area of low pressure over Georgia and the approaching upper level system over the Great Lakes. As his energy merges with these other features, it will become quite the extratropical system, throwing quite a bit of rain across Southern New England.
The rain should start sometime before dawn on Saturday and while it won't be heavy all the time, it should be persistent with possible tropical downpours. We'll be on the western fringes of the heaviest rain, but we should see the forecasted amount of 1-2 inches of rain during the day on Saturday. Models still show the rain tapering off sometime after dark and should be completely over around 11:00pm Saturday night.
Sunday still looks unsettled with scattered showers as the upper level low pulls away.
I would suggest putting at least a couple of the storm windows up on Dave's. That way we can least open a couple windows to let some natural light in on Saturday while still keeping the rain and wind out.
I'll be monitoring the data all day today and if an update is needed, I'll make a note of it at opening. See everyone there later tonight!
