The most elementary way of verbalizing the forecast through much of this week…sun to storms.
An upper level low is meandering around Northern New England through Thursday. This low pressure system will have pulses of energy spiraling around its vortex. These ‘pulses of energy’/pockets of cool air will allow for diurnal clouds to build and showers and storms to develop during the heat of the day. Highs will stay on the cool side today near 70F, give or take a few degrees. Then, high temps will begin to rebound on Wednesday as highs reach the mid-70s. Thursday will be even warmer in the lower 80s. There will be less of a chance of spot storms by the time Thursday arrives as the area of low pressure begins to ‘fill-in’ and move northeast. Here’s a pictorial view…
The jetstream becomes more zonal this weekend allowing for quick moving, weak disturbances to sweep through the region. Friday will mainly be dry with highs in the middle to upper 80s. However, at the moment, the best chance of a shower/storm is going to be on Friday night-Saturday morning. Then, most of Saturday and Sunday are looking dry and much warmer around 90F, plus or minus a few degrees. Even the Cape/Islands will be aiming for high temps in the 80s! Can you say, ‘Beach Days’?! :) Speaking of beach and boating, here is a link to check out the latest forecast, thanks to the National Weather Service.
Then, there is Tropical Storm Debby, which is barely moving to the east at 3mph with maximum sustained winds at 45mph (per 5am update).
