Wont change title numb ens despite being close to that for just the first storm.  I think I want to see what we have on the ground by 8P Tue before I 2" to the weekly total.  I think we have our hands pretty full with Tuesday-Tuesday night. 

@wdrag any additional thoughts on the Friday/Saturday storm?

The good news from a forecast confidence perspective is that all the models agree on the heavy rain and flash flood potential. So we have excellent agreement in that part of the forecast. The more tricky part of the forecast is the high wind potential.Several pieces of guidance like the Euro/EPS/RGEM/and HRRR loop the low back closer to MTP. Since that part of the forecast would be Wednesday night, there is time to issue high wind warnings after the 0z runs tonight should they be necessary. The HRRR gusts in knots would require high wind warnings for Long Island. Storms that loop back west are notorious for wind damage near their paths.

RIP LI power if the HRRR verifies

The Euro has been showing this potential since yesterday at least.  The question is whether these winds mix down over land vs the coastal waters as modeled.  SLP won’t be deepening as it retrogrades to the west and SW over the coastal areas.  It will have leveled off in intensity as it makes this motion and would tend to help spare land areas.  Models that bring the center of SLP closer to the NY region have been relatively consistent with the idea of the strongest winds mixing down over the coastal waters.  You won’t have to go far to find these winds as they would rake areas including LI Sound and the Great South Bay.

This.   I don't think the winds would mix down to the max potential once the heavy rains are done-by the time the wind field gets here alot of the  heavy rain is largely done.   So we'd have winds but maybe 50% of what the models are showing.

There is no question that the departure of the heavy rains is going to effect the ability of the stronger winds to mix down.  That’s a given.  When the first round of heavier echoes went through my area earlier I gusted to over 20 mph. Now it’s back to almost calm with the lighter rain that I am seeing now.

At this point, I see a sizable event,  slower than currently modeled but my interest is what is going on now.  Just pounded 3/4" in less than hr here and i see 2+ inches to my east where a flood warning in effect.  I think we've got a big problem ahead for parts of our forum. Wind rain-power. It's been underplayed too much.

I agree I think most people are underestimating this.
