NH1 Weather Insider with meteorologist Bill Gile for May 27, 2016


We'll be in the battle zone between summertime heat and cooling springtime conditions this weekend as a waffling frontal boundary over NH determines what our temperatures will be on a day-by-day basis.

We will be in the warm sector Friday with highs in the 80's as a warm front lifts north of the region. There will also be a threat of a pop up PM shower or T'storm as well as dew points begin to rise and it starts to feel muggy. Any showers will dry up overnight into Saturday morning.

An upper ridge axis will continue over New England through the weekend and into Monday. This ridge will be what we call a "dirty ridge" as several minor short waves combined with ample moisture will move through the ridge before getting dampened out and setting off scattered showers and thunderstorms at times. Under the ridge, a surge of summer-like air for Saturday with highs in the upper 80's and Lwr 90's! Even some Lwr 80's at the beach. After some morning sunshine, clouds will build during the afternoon that could yield scattered afternoon showers and thunderstorms. A few storms could be quite strong with heavy downpours, strong gusty wind and hail across central and southern New Hampshire.

A "backdoor" cold front will push southwestward from Maine Saturday night and Sunday morning as High pressure builds over the Canadian maritimes. The High will wrap in cooler onshore winds from the east and drop our temps back into the 70's Sunday, even 60's at the beach! Low clouds & fog will also back in off the water making for mostly cloudy skies Sunday with the risk of a few widely scattered showers possible. The high off the coast will supply enough dry air to keep most of the region dry on Sunday, with brighter skies inland away from the coast. Memorial Day will see winds shifting back to the SW and temps climbing into the 70's and Lower 80's as a warm front once again lifts through NH. Skies will still be fill with clouds, a few breaks of sun possible and the chance of a few pop up shower or two.

As we head into the middle of next week temperatures look to hold pretty close to 80 under a mixture of sun and clouds.
