The Upper low over james Bay continues to wrap in seasonable dry and cool weather into the Northeast today with breezy WSW winds.  There are more clouds north with partial sunshine. In the south, sun filled skies all morning through the early afternoon before clouds begin to build & increase during the afternoon. Highs in the Lwr-mid 60’s.  Not as windy, but still an active wind which could still gust to 30 from time to time.

Clouds will be thickening tonight with a weak front/shortwave, which will push through with a few scattered showers or sprinkles overnight.  best chance of any showers will be farther inland. This front will quickly push offshore Monday with drying west winds behind it. Skies will be increasing with sunshine Monday with temps right back into the mid 60’s with breezy west winds.

Though the weak front pushes off shore, it will be stalled off the coast. This stationary front will become a warm front Tuesday as warmer air begins to shift back up the coast thanks to a developing trough along the east coast with SW winds aloft. Though this front may trigger an isolated shower as it pushes back north, it will mainly be the focus for increased clouds and warmer temps following in behind the front, especially in SE MA where temps could climb into the upper 60’s. On the cooler side of the front, more clouds and cooler temps in the Lwr 60’s.

We are watching the tropics off the coastline of the Yucatan Peninsula where tropical storm Rina may form today. It is looking more organized today. This will become absorbed by this digging trough on the east coast and be directed up the eastern seaboard as a moderate to possibly even major rainstorm.  As an upper low digs into the trough, a surface low will track up the coast through the Mid-Atlantic Wednesday and through upstate NY by Wednesday night. This will come with mild tropical air up the coast along with heavy downpours/thunder which could make for a quick 1-2+” rainfall. Some localized flooding could be possible with the passage of this low.

Drier and cooler air will be wrapping in behind the departing storm , but lingering showers are possible Thursday, especially across the north. Temps will be dropping into the 50’s with breezy NW winds with building high pressure heading into next weekend with increasing sunshine through the weekend.  Cooler air aloft will likely aid in stratocumulus with the daytime heating…into Saturday.
