Rain Will Pick Up In Intensity This PM

It's a dreary morning with fog and a few showers.  Temperatures are in the mid to upper 50's.  Temps will max in the low 70's.  Saturday will be windy and much cooler.  Although high temps will be in the low 60's tomorrow this will occur in the morning before crashing in the afternoon as the west wind picks up and gusts to near 30 MPH.

General Overview
Here is the northeast regional radar loop as of 630 AM.
NWS Northeast Regional Radar Loop
The actual cold front responsible for all that heavy rain in the Ohio Valley and up into PA and NY is a slow moving frontal boundary.  Its unlikely we see much rain from the actual front as low pressure tracks into Northern New England.  Still the involvement of subtropical moisture will produce locally heavy rain this afternoon as precipitation will be enhanced by the offshore passage of that storm.   Simulated radar at 2 PM shows some rain bands beginning to work across SNE.

Given the atmospheric situation we could see some thunderstorms this afternoon.  I would peg the threat between 2-10 PM.  Here is the 6 PM radar

This model shows Eastern MA and RI getting crushed with rain this evening.  Moving forward to 10 PM

High school football games in CMass, EMass and RI will be wet (and possibly delayed by lightning).  The storm will produce a dry slot but not until after midnight.  Drizzle and fog will remain through Saturday AM.   Total rainfall is 1-2" (locally higher).  Temperatures will be in the 60's when we wake up tomorrow but dropping hard in the afternoon.  Some showers are possible through early afternoon.  I will update tomorrow morning on the wind potential as some areas will likely see wind advisories posted.
