Heat & Humidity Breakdown...For Now
Cold front is on the move this morning but it is taking it's good old time getting to the coast. Dewpoints have started very muggy in the upper 60's and Lwr 70's but have been dropping behind the front once it passes. Drier air is already in place across the north where the dewpoints have fallen into the Lwr 60's in Portsmouth, Concord, Nashua and Lawrence. Along and south of the Pike it is still humid and will likely remain so into the afternoon before conditions start to feel a bit more comfortable heading into the evening.
Abundant cloud cover remains over southern New England. Periodic light showers have crossed this morning with a shortwave riding ahead of the front. High pressure over Canada will edge closer towards the region with increasing sunshine and drier air for the Northern new England. Across the south is a bit of a different story.
Mostly cloudy conditions will be in place for most of the day with periodic light showers south. Highs will be warm in the Lwr-mid 80's. With the front pushing off the coast, winds are out of the NW and will be shifting to the NE to provide cooler and drier air to penetrate during the afternoon. Cooler NE winds colliding with warmer tropical air may trigger a few afternoon storms along a sea breeze front...hit or miss...especially through CT, RI or SE MA...closer to the proximity of the front. Clouds and warm air aloft will help to cap much in the way of any convection. Drier air from the north should help to break up some of the clouds later today to give way to breaking mid-late afternoon sunshine.
Partial clearing tonight with lower humidity and lows dropping into the 60's. High pressure crest over us early on Monday with mostly sunny skies briefly...clouds will be increasing and start to cloud over by afternoon. High pressure offshore will wrap in cooler SE winds which will be cooler and more comfortable 70's. the next round of showers and thunderstorms will come late Monday after noon west...with most seeing showers and storms Monday night and early Tuesday from a cold front with will push through.. Upper level trough over us Tuesday will provide instability for a few afternoon scattered showers or storms...especially for the N & W.
Ridging will begin to return and shift back east for the middle to end of the week with warming temps and becoming more humid. Highs will edge back to near 90 or greater by week's end. Friday appears to have a few showers or storms with another shortwave passing through. So the summer heat does return with nothing as extreme as this past heat wave.
Looking ahead into August, it looks like a bit of a weak trough will sit across the Northeast...which should help to prevent any BIG heat through the 10th..still plenty of summer to go!
