NH1 Weather Insider with meteorologist Bill Gile for May 22, 2016
Saturday will be the pick of the weekend as High pressure will be moving through southern New England. Highs will be able to climb into the mid-upper 70's inland with Lwr-mid 70's at the coast. Skies will start off with sunshine and become partly sunny by the afternoon as clouds increase.
At the same time, an Area of low pressure will develop off the Mid Atlantic coast. Most models have this low taking a far enough track away from New England that the heaviest rain stays over Cape Cod. However, that doesn't mean we are completely out of the woods. The NW side of the system will feature some showery activity moving in tonight and early Sunday. Another problem will come from a cold front that will drop down form Canada Sunday and stall over us. With a colder pool aloft and daytime heating, this will be a trigger for a few pop ups showers Sunday afternoon for western and northern areas and some of them could be locally heavy. Highs will be cooler in the 50s to low 60's Sunday. So, not a washout by any means...just not as good as Friday or Saturday.
Beyond the weekend low pressure, and upper level trough is forecast to close off and cut off from the jetstream. The resulting upper low will meander over New England thru early next week. Temperatures should be comfortable in the 60's and Lwr 70's. Monday will be basically dry under partly sunny skies, but a spot shower can't ruled out. Tuesday is a day we will have to watch for periodic showers being directed into New England off the water. The upper low could still help to trigger a scattered afternoon thundershower on Thursday as much warmer air will be shifting eastward in time for the Memorial Day weekend with some Lwr-mid 80's in the forecast Thursday through Sunday! A summery feel to unofficial start to summer!
