The upper Low in Canada which has helped to to supply the cooler dry air of the past few days is weakening and shifting east. This NW flow aloft helped to steer weather disturbances away from New England. With it's departure, the window is opening up for rain to enter the Northeast/ New England. Another wave of low pressure will track towards the Mid-Atlantic through Monday. Showers and rain will be spreading into New Hampshire Sunday afternoon with highs only in the Lwr 50's and 40's at the coast. Rain showers will developing around midday through afternoon and early evening. It will be a damp raw day.
The periodic rain and damp cool conditions will last through Monday with temperatures stuck mostly in the 40's. A low will track along the south coast Monday with periodic rain and the potential for some localized heavier rainfall. Most all of this wet weather winds down Monday night and by then we will have picked up close to 1/2" - 1" of rain, so this should be a nice rainfall to relieve the fire threat.
Temperatures will start to warm back up into the lwr -mid 60's by the middle to end of the week, but the upper level low pressure system will still be meandering around the Northeast which will give us a good deal of clouds and a threat of showers Thursday, Friday and especially Saturday. This is a typical springtime pattern that we deal with almost every year and sometimes can take 2 weeks to begin breaking down. So each day that the winds come in from the east or northeast we'll be cooler, but when they shift more southeasterly it won't be quite as cool.
This weather setup looks to last into the start of next week for the northeast keeping any summer like warmth south of New England for now. Temps are looking seasonal to slightly below normal through at least the middle of May....still seasonal air this time of year is in the 60's with sunsets around 7:45 PM, though.
