Steady Rain Tomorrow

The Major League Baseball decision makers must have known something when they made the 2017 schedule last summer.   Boston hasn't hosted opening day since 2010 and you couldn't ask for better early April weather.  The reason MLB usually waits a week or so is because early April New England weather can be awful.  The Sox are off tomorrow which is a good thing because a storm system will track to our west, bring heavy rain and some wind.  A few communities along the MA/NH border may briefly mix some frozen precipitation but most of us are all rain.

Short Term Forecast

Temperatures tonight will fall into the upper 30's tonight.  In Essex County by the NH border, we may end up close to freezing so please careful if you live up that way as the roads may briefly become slick.  Clouds will be on the increase this evening as the system works north and east.
NOAA/NCEP/NWS GOES_East visible satellite 415 PM
Rain will arrive just before midnight in Western CT/MA and around 2 AM in Central and Eastern MA/RI.    Here is the 18-hour simulated radar loop through 9 AM tomorrow.

The surface low is will still be well to our west tomorrow morning.  So even if we get a brief break, more rain will fill in tomorrow afternoon.
WPC Surface Fronts/Precipitation Tuesday 8 AM
There are some signals that there could be thunderstorms tomorrow, mainly south of the Mass Pike.  While these will not be severe they will add to the rain totals.
SPC Tuesday Thunderstorm Outlook
One final batch of rain will cross the region tomorrow evening as a new surface low forms over Southern New England.    Temperatures tomorrow will be in the upper 30's/low 40's.

Total rain will be 0.75-1.5".  Highest totals should be near the South Coast.  The National Weather Service in Boston does not agree with me, but the New York City office does.

We are only talking 0.25-0.5 difference but rivers are actually running high.  Some streams and rivers will approach minor flood stage tomorrow.  Many rivers will approach minor flood stage by the end of the week. 

I will update in the AM.
