More Classic New England October Pattern Setting Up

Strong Nor'Easter Closing In...

While the storm will be much weaker Saturday, the onshore wind will continue and likely will deliver areas of steady drizzle and light rain.  The wind finally shifts Sunday, affording sunshine for the final two days of the holiday weekend and temperatures returning to the 60s in our exclusive First Alert 10-day forecast.
