Stalling Front Will Mean Increased Humidity and Chances of T’Storms

Gorgeous day in progress with sunshine, lower humidity and a gentle onshore wind. Highs will be climbing into the upper 70’s and Lwr 80’s inland. Beaches will be cooler with temps in the upper 60’s and lwr 70’s. A beautiful clean airmass with a front currently stalled at out south coast. High pressure to our north is the supplier of the refreshing new airmass…unfortunately, it won’t last long.

First things first…just a reminder before heading out to enjoy the day:

The EPA has us with a very high UV index of 9. Ultraviolet (UV) radiation from the sun is expected to be unusually intense.  EPA strongly recommends that you take the following steps to reduce risk of overexposure:

-Be mindful that UV radiation is highest from 10:00 a.m. to 4:00 p.m. and protect yourself accordingly.
– Cover up by wearing a wide-brimmed hat, UV-protective sunglasses, and long sleeves.
– Generously apply a broad spectrum sunscreen with UVA and UVB protection and an SPF of at least 30 to exposed skin.  Reapply every 2 hours.
– Use extra caution near water, snow and sand as they reflect damaging UV rays.
– Whenever possible seek shade in the midday hours.

Sunshine will last for most of the day, with high clouds increasing later in the afternoon. This stalled front will begin to push into SNE this evening as a warm front with increasing cloudiness. This will provide enough lift to possibly spawn a few scattered showers or a thunderstom later tonight into early Monday. This front will stall over SNE Monday, with NH, ME and the coast on the cooler side of the front and a more marine airmass with SE winds. ..in the 60’s and Lwr 70’s. Inland heat and humidity will build with southerly winds in the CT river valley with temps climbing into the 80’s. Where there is greater heat and humidity, there will be a better chance for a few strong to severe storms could form, especially farther inland away from the coast. The cooler more stable marine airmass whould help to keep much of Monday faily dry across eastern MA, Where thunderstorms do form, there is the potential for locally heavy rain along with lightning. Best chance of a few storms to pop tomorrow afternoon will be in Northern and western New England later in the day. Clouds will be the rule Monday, but I can not rule out a few breaks of sun around midday.

The warm humid weather will continue through Tuesday and Wednesday. The stalled front does not budge Tuesday. More of ther same with cooler temps at coast and wramer inland.  STRONG TO POSSIBLY SEVERE THUNDERSTORMS POSSIBLE MON NIGHT AND TUES near the proximity of the front and the highest heat and humidity. Still the potential exists for a few storms break away from this front and make for a few scattered storms to reach the coast. Atmosphere will be loaded with moisture so any rain that does fall will come with downpours. As low pressure track to the Maritimes a cold front will push through early Wednesday taking the humidity and risk of T’showers along with it.

Weak high pressure builds in for Thursday and Friday with lower humidity, 70’s… before another more vigorus weather system digs in and comes up the coast to possibly effect the start of the weekend with more rain and cooler temps. The overall unsettled trend continues in the Northeast. We have picked up over 3″ of rain this month. The five day forecast for precipitation totals shows the potential for more beneficial rain fall in the coming days.
