Missed out on action today. Any chance these cells make it to the coast overnight?

Don't see any reason why not. Reservoir of 3000 J/kg sitting over SNE.

Had one make it to the coast here.  Essentially started 15 mi inland then popped just as it made it to PWM.

So just getting back inside after a great afternoon . Around 230 watched mammatus type development overhead and then heard thunder. Brought in all the  deck stuff and dropped the umbrellas, watched a tower explode, had constant thunder and lightning a brief period of small hail and heavy rain. That cell had excellent up drafts and went on to create, quarter size hail in Cory’s hood. Cool storm

You were right there on Seekonk?

Yeah. The storm that passed over Providence moved south of me. Got some rain and a little wind but no lightning and only a bit of thunder. Thats how things usually happen for me. The storms either break up before reaching me (only to re-form to my east) or pass me completely.

Pretty breezy ahead of this line. Worried about my potted trees. 

Are you the lady that calls us from Limerick every time there is a heavy thunderstorm?

Definitely would not be surprised to see something in the 25-30 knot range. That's pretty much been the standard across the line in the last hour or so.

Hi! I totally missed this thread yesterday and I hope I can be forgiven for that.

So I was in the storm that was  in the video in Cumberland RI (I was in Lincoln RI). I have a meteorological question about  what I experienced today. 

The cell that affected my area had been tracking to the south of me - it should have passed to  my  south. However, it broke into two parts. The part that hit my  area actually moved towards  the east northeast, when the prevailing direction of the front was moving towards the east southeast. I didn't anticipate that, so I was late getting to a place to watch it (thunder allerted me - then I checked radar and saw what had happened). By the time I could see outside, I saw some pretty good  winds going, but no precipitation. I could still hear thunder. But my question relates to this next observation: it began to hail before it  began to rain. 

I've  tried to search online to see if this is where  the hail normally is in a storm (in front of the rain), but I haven't been able to find anything specifically about the location of hail in a side-view of a thunderstorm. I found one image that showed a tornado in front of the rain, however.

Can anyone let me know if this is normal?

Although  we did not have the same  size (consistently) of hail as the video  from Cumberland, I did find one quarter-sized hail stone (it is in my freezer, lol). It is amazing what a big difference a small distance can make in these  storms. I was maybe a mile from the Cumberland line as the bird flies - possibly less.

Any education that somenoe can provide would be greatly appreciated!!

It was a splitting supercell. Hodographs were fairly straight to begin with (storms tend to split with a right mover and a left mover). Typically our winds in the northern hemisphere favor right movers, but the hodographs actually had a slight cyclonic curvature. This actually favors the left moving supercell a little. So the storm that broke NE was the left mover.

Based on overall shear/storm relative winds precip would be carried ESE out of the updraft. So the left mover would actually be moving into clear air, whereas the right mover was moving into the area just hit by its own forward flank.
