A warm front is bringing precipitation to Northern New England this AM. It will slowly shift east this afternoon/evening. Showers and thunderstorms will be a threat on Saturday in SE New England as the warm front will linger in our neck of the woods. By Sunday the front will be in the Atlantic/Eastern Maine. Temperatures will rise into the upper 60’s/low 70’s today but will be in the mid to upper 70’s on Saturday. A few low 80’s readings will be possible in the CT River Valley. Most people reach the low 80’s on Father’s Day but dew points will return to the low 70’s, even up in the Lakes and Mountains of Northern New England.
Rain will begin around 11 AM in CT and between 1-2 PM in Central Massachusetts. The rain will be scattered and showery in nature in Southern New England. In Northern New England, steady rain is moving from Upstate NY into Vermont. Steady rain is also moving through the White Mountains of NH and Northern ME.
Over the next 18-hours the radar coverage will fill in, but it won’t be as widespread in MA/CT/RI.
The rain will hold temperatures in the mid 50’s in Maine today. 60’s will be the dominant reading across MA/CT/RI.
Dew points today are around 60 in Southern New England and in the 50’s in Northern New England.
Here is the forecast surface chart Saturday 8 PM
The front will stall, splitting New England from NW to SE. There isn’t a lot to generate showers and storms but the boundary will be able to fire off a few storms. Dewpoints will rise into the upper 60’s. You can see where the model thinks the frontal boundary is at 2 PM by the difference in dews. Low 60’s in Maine versus upper 60’s in Connecticut.
Air temperatures tomorrow.
Ocean temperatures are getting warmer but thunderstorms will be possible from Misquamicut to Mayflower tomorrow, especially in the morning and early afternoon.
Sunday is Father’s Day and if he wants to be left alone at the pool or beach then the weather will cooperate. The warm front will move to our East, firmly establishing heat and humidity across the region.
Here are the forecast dewpoints. Maine and New Hampshire get in on this action as well.
Air temperatures will be in the low to mid-80’s.
S NH and NE MA will be one hotspot while the CT River Valley will be another. Only a slight chance of a shower or thunderstorm on Sunday but given the uncomfortable air mass a few will be possible. A bigger chance for severe weather is on Monday.
