A Gloomy Stretch...
After days of warm and mostly sunny weather we are now paying the price...three straight days of gloomy weather. A frontal boundary that slipped through late last night and dropped temps ten degrees in a short time is stalled in our coastal waters to our south and winds have shifted to the NE drawing in cool maritime air from the Gulf of Maine. With the cool air entrenched at the surface, moisture is riding up and over the front and then the cooler surface air, providing enough lift (via overrunning) for occasional rain through Thursday. The heaviest of the rain should fall tonight but there is no flood threat from the rain in Central or Eastern MA. In fact, I don't see any washouts just scattered showers tomorrow and Thursday with patches of drizzle too. This moisture is indirectly related to The remnants of Tropical Storm Lee, which is spinning over Nashville, TN right now. The storm will work into the Northeast on Thursday and retrograde into the Ohio Valley on Friday which is when the sun will start to poke through the stubborn clouds finally.
Also of concern is Hurricane Katia...she has been steadily weakening now down to a CAT 2 with winds of 105mph. The official track from the National Hurricane Center keeps her well offshore and not effecting any of the East Coast. With that said, the beaches will take a beating for several days with rough surf and rip currents.
