FRIDAY- Today is one more day of perfect weather. Then we will start to get into unsettled times for what seems to be for at least a week. First tomorrow will be a day that features sun in the morning and temperatures that will rise to around 80 degrees. A line of thunderstorms, some of which may be strong to severe, will move through our area later tomorrow night, similar to Tuesday night, and then we will see the cold front stall out on the shore early Sunday morning that will allow for rain showers to train over SNE much of Sunday morning. Eastern New England has the best chance of rain early Sunday morning for Father's Day. Temperatures will be quite cool with highs in the mid 60's along the coast to around 70 inland. Some places on the Cape will struggle to get up to 60 degrees on Sunday. Then we have to look towards an unsettled stretch for quite a period...showery and cool weather for days.
This will all be courtesy of an upper level low in eastern Ontario that will keep the atmosphere unsettled and cold aloft and coupled with daytime heating will always bubble up some instability showers and maybe a thunderstorm through the period. The afternoon hours will be the cloudiest and for this, afternoon temperatures will struggle to come up over 70 degrees Tuesday through the end of the week. Overnight temperatures will be chilly and allow us to rest the air conditioners for a while, which is a good thing in my point of view.
I'm seeing indications that we could stay cooler than normal for about the next two weeks before we heat up again in the last days of June and heading into the Fourth of July holiday.
