Soako De Mayo This Year

Showers this morning will give way to heavy rain this afternoon as low pressure slowly lifts northeast from the Ohio Valley into Western New York.  Rain may let up this evening before more rounds of showers return Saturday AM.  There is a traffic jam in the upper atmosphere so expect clouds and showers for the next several days.  I can't claim credit, but it looks more like Soako de Mayo than Cinco de Mayo.


Right Now
Here is the northeast regional radar loop.  Look at all that precipitation on its way to Southern New England (SNE),

Because of all of this rain, the National Weather Service in Taunton has issued a *Flood Watch* for parts of SNE, including Southern Worcester County.
NWS AM Headlines
Temperatures as of 5 AM were in the mid 40's across most of the region.  Temperatures are expected to stay in the upper 40's/low 50's for most of the day.  Temperatures will likely jump into the 60's across the Southcoast and parts of Southeast MA tonight when SNE enters the warm sector.

Today
Here is how the low will track over the next 24 hours beginning at 8 AM today and ending 8 AM tomorrow.
WPC Surface Fronts/Precipitation Friday 8 AM, 2 PM, 8 PM, Saturday 2 AM, 8 AM 
Expect showers until 12-1 PM and then the action will begin.  As the warm front gets closer to SNE some thunderstorms will embed within the rain shield.  The evening commute looks horrible if we are being honest.  We will catch a lull after 8 PM or so.

In the Blackstone Valley, the worst will be between 2-7 PM this afternoon.  In EMass the worst will be between 4-9 PM.  Here are the expected maximum temperatures today.  These will occur tonight.

Winds shouldn't be a huge problem with this storm but gusts of 30-40 MPH this evening are possible across the Cape and Islands.

Friday Night-Saturday Morning
The axis of heavy rain will continue to be over EMass (which is why flood watches are up) as the storm passes to the west.  It won't rain constantly, but the lulls will quickly be replaced by showers and thunderstorms tomorrow morning.    Temperatures will creep into the mid 60's for most of the region tomorrow AM.  Here is the simulated radar for 11 AM tomorrow.

At least it won't be a cold rain?

We will have to keep an eye on the Blackstone during this weather pattern but I am not expecting any issues this weekend.  It's a good thing we didn't get this storm after all the rain in the middle of April.  That would have brought the river out of her banks.
