Dry Saturday, Wet Sunday-Monday

High pressure keeps Southern New England dry today but a cold front approaching from the west will bring needed rainfall overnight tomorrow through Monday.  It looks like Southeast New England stays dry until tomorrow afternoon, including Foxboro for at least the 1st half.  Monday appears to be wet with a chance of embedded thunderstorms as the cold front passes.  Extreme drought is increasing across MA and NH so we will take whatever we can get.

General Overview
Here is the AM water vapor satellite loop.

Initial sun this morning will begin to give way to high clouds as the system continues to push east.  As it does a few showers and thunderstorms could interrupt the Florida State-Louisville game in Kentucky this afternoon.  Here's hoping for a thunder delay so I can watch the end of the game.  Back in SNE temperatures are firmly in the mid 70's today.

High clouds will begin to filter out the direct sunshine this afternoon.  As we approach the later parts of September the sun rapidly loses its strength when filtered by any type of cloud so expect it to feel chilly this afternoon at times despite a wind shift to the south.  Here is the forecast surface chart at 8 PM.

As we approach Sunday AM it will be raining in Western and Northern New England.  The cold will be slow to approach thanks to high pressure in the Atlantic fighting off the approach best it can.  Here is the Sunday 8 AM simulated radar.

At 2 PM we see rain knocking on the door of NYC, Philly, Boston and Washington.   The Steelers, Panthers, Redskins, Giants, and Patriots are all home at 1 PM tomorrow so weather could be a factor in all of those games.  Here is the current simulated radar for kickoff.

I would like to see tomorrow mornings model runs and radar trends but as of now only Giants-Saints and Steelers-Bengals looks to be negatively impacted by weather.   Rain will overspread SNE by Sunday evening.  Here is the cold front Monday AM.

The simulated radar (which is probably junk at this range but it gives the idea that heavy rain is possible/likely in our region) at the same time.

Temperatures will be in the low 70's as this moisture has a slight tropical connection thanks to Tropical Depression Julia which is weak off the Carolina coast.  I will update tomorrow.
