Warm Friday, Unsettled Saturday

After beneficial rain yesterday Friday is looking spectacular.  This is good news as the Saturday forecast is not looking good.  Sunday is a compromise between today and tomorrow; not as warm, not as wet.  Please note the National Weather Service has issued a special weather statement regarding locally dense fog this morning as winds are light and the air mass is juicy.

Observations/Short Term Forecast
Here are yesterday's rainfall estimate from the NWS radar out of Taunton

One cell in particular stood out near Braintree around 5 pm last night.  I saved the image as there were reports on twitter of a funnel cloud with this cell.  Others in the field noted that the velocity fields indicated rotation.

Thankfully nothing like that on tap for today.  For the first time in a few days the Northeast radar is pretty quiet this morning.  Of course this break is short lived as you can see the cold front advancing into Western PA

Low temperatures will in the mid to upper 50's.  The front will organize and take on a classic look of lifting warm front in Southern Canada and a long trailing cold front down the east coast.

Here is the thunderstorm outlook from the SPC.  They do not anticipate severe thunderstorms but I think an isolated strong cell is possible tomorrow afternoon.

Overnight lows Saturday into Sunday will be mid to upper 50's, but cooler in the Mountains of Western MA.  On Sunday we transition.  Clouds will burn off throughout the day and the afternoon will be in the low to mid 60's.  This will make all our Mother's happy and when Mom is happy the whole family is happy (at least the males).  Have a good day!
