NH1 Weather Insider with Joe Joyce: May 4, 2016

NH1 Chief Meteorologist

A new has dawned, and while the political landscape has shifted, much remains the same in terms of the weather. This prolonged stretch of cloudy, cooler, unsettled weather continues. A deep upper level trough is digging in on the east coast, all within a large scale upper level blocking pattern which has been in place the past two weeks making for a variety of weather, and at times extreme severe weather across the midwest. With energy pouring into the trough, and a SW flow up the east coast, this will help to create a series of lows which will track near or close to New England this week. Temperatures will average slightly below normal in this regime. There will be times when it is dry, but there are going to be a few times of showers which will be fine tuning along the way.

High pressure over the Canadian Maritimes will help to reinforce the cool onshore flow, yet also supply the dry sinking air helping to keep NH mainly dry again Wednesday. While most of the rain will stay just away from us Wednesday, a few widely scattered showers can not be completely ruled out during day with highs in lwr-mid 50's, along with cloudy skies. Our next chance of showers and rain will come later Wednesday afternoon just in time for the evening commute as a low generates off the Mid-Atlantic coastline and tracks closer to New England. Periodic rain and drizzle develops Wednesday night through Thursday midday. Along with cool NE winds at the surface, low pressure will track along a stalled front south of the region and eventually pull away. Weather will be slightly drier by Thursday afternoon. Highs in the Lwr 50's. Not ideal weather by any means..

Friday looks dry for now with low clouds locked in place with onshore winds. Another low will gather south of New England and could spread rain into Southern New England later Friday afternoon. A few showers may break off and push into NH Friday night. The low will weaken and fall apart Saturday, but the clouds will remain, as well as the risk of a periodic stray shower. Highs will be be milder this weekend in the Lwr-mid 60's.

A cold front will sweep through Sunday with a few more showers. It looks like midday showers be the best timing into the afternoon. Behind this front will be a flood of milder dry, but cooler air with skies . Highs near 60. Cooler breezy conditions with brighter skies Monday. Highs near 60. An upper level ridge will be shifting east and temperatures will be climbing into the lwr 70's by Tuesday and even warmer 70's by Wednesday. Unfortunately, that ridging will not stick. A trough will be returning to the pattern by May 14th in the Northeast, with a return to slightly cooler temperatures. This trough could linger in the northeast through May 20th. Oh well. We take the good with the bad. It could be much worse.
