It appears any lingering questions some may have had of where the the heavy rain would set up has been answered.. Looks like we've got ourselves at CT/RI/coastal SE Mass deluge situation.

WB 0Z EPS is wet next two weeks.

Zzzzzz maybe .25 overnight while the HRRRRR had over 3 inches for the same period

1.3 last night; best rain in forever....another round of storms later this afternoon/evening. WB 6Z 3K NAM.

73 for the low up here. Got dry slotted on most of the rain only .15” of rain up here. Hope everyone gets their power back soon. What’s the old saying? When it rains it pours.

Let's keep South

New July BOM model run for region 3.4 and region 3

Just a WAG, but I think this week marks the beginning of a transition to legit Niño conditions i.e. wetter and cooler than normal. We'll see.

Nailed it!

I saw that... im starting to learn the dynamics out here as things approach from the west. The last several systems seem to jump north as they approach so for me I need things to be down your way as they get closer if I want to cash in at least so far that is how it's been. I did get 0.48 out of it I'll take it!

495 has been the screw zone so far the last 2 days. Hopefully you all cash in today and tomorrow. That line almost missed me last evening but it extended down just briefly, and damn was that rain intense.

Just a WAG, but I'd day there's a 5-10% chance the winter (DJF) north of MD/PA border will average BN, but a 50/50 chance 1 month could end up BN with February being the best chance. Fwiw, I think March has a 60-70% chance of BN, though only slightly.

Damn it, I forgot to cover the grill before bed last night after making burgers

Btw last nights “fireworks” were an unbelievable light show like I’ve not seen in a long while.

4.76" since 7pm last night here near Campbell Hall.

Same here in Hanover and 1.28" at York airport 8-9 miles to my ENE. 6." Saturday night.

0.05" in the past 24 hours. lol. i give up.

0.32 on 7/4 0.69 on 7/5 0.00 overnight At least it’s something against my rain deficit.

What a mess. No power since Saturday eve and got pummeled last night once again. 1.77 sat and last nights deluge put 1.64 on top of that. water in basement. Not real bad but need power. I’m nervous at how long that’s going to be until it back. Lookin for generator today as well as places to move frozen foods. Good luck to alll affected.

Pretty unimpressive so far, heavy echos dried up on arrival and kinda just showery all night.
