Saturday Update 8:30AM: Today’s surprise is that the low doesn’t look like it will develop as deeply as previously forecast.  That means less precipitation and less cold air being brought in.  Just light intermittent rain showers today and especially this evening.  Too warm for snowflakes.

As mentioned the other day, a weak disturbance moving along a frontal boundary will develop a surface low pressure system when it reaches the coastline.  With these scenarios, there are occasionally surprises in either direction; sometimes the low is much stronger than predicted and sometimes weaker.   Here’s the current model forecast:

Light snow will likely develop later tonight, giving us a coating by morning.  Very light snow changes to light rain and  continues on and off during the day Saturday, with an increase in intensity late afternoon and early evening.  High temperatures around 42.  (Average high is 55.)

There may be a shift back to wet snow early evening, then light snow through Saturday night, ending Sunday morning.  Another coating, up to an inch, is forecast by Sunday morning.

Light snow ends very early Sunday morning and skies clear by afternoon.  Temps remain below average with a high of 44.
