Mother's Day Weekend Forecast

It is absolutely pouring in the Mid Atlantic this morning as a surface low curls inland.  Meanwhile reports off the twittersphere are indicating breaks of sun in Eastern MA.  It's been awhile since we've seen that.  See this post for the Friday forecast or check out the video.  I'm going to focus on Saturday and Sunday here.

The upper low responsible for the rain in the Mid Atlantic will sit in the same region spinning up occasional showers and thunderstorms Saturday.  In between these bouts of rain there could be some sunshine Saturday PM.

Checking out the simulated radar at the same time we see isolated showers throughout the Mid Atlantic and Southern New England.  Flow around these low pressure systems is counter clockwise so Southeastern MA, RI will have the highest chance of rain tomorrow.

Temperatures will climb to 60-65.
NWS Boston Max Temp forecast Saturday 
Temperatures Saturday night drop into the mid to upper 40's.  A cold front will finally kick the upper level low offshore on Sunday morning.  The price to pay is Sunday morning rain showers so if you are out to breakfast with Mom bring an umbrella.  They will be quick moving so it's all good for the afternoon as skies will clear by 2 PM and temps jump into the low to mid 60's!

Monday is really nice as well.  I wish I could say this is a permanent change but we have more shots at precipitation next week.  We can worry about that later.  Have a nice weekend and Happy Mother's Day.
