Outflows clashing with each picked up a half inch of rain so far in 20 minutes and the storm motion is just about stationary. Would not be surprised to see more action pop up to the west and fill in just north of DC area.

Yea hearing major flash flood issues in ellicott city again radar estimates of 5" in the last 2 hours 3 of which happened in the last hour.

Reporting about 1.1" fell at the airport itself asos a half mile away to the south got .67" Areas in Baltimore are surely flooding bad there were issues on my way down at I83 and 695 and that was about 2.5 hour ago so can only imagine what that is like.

Ellicott City has now had this storm sitting over them for nearly 3 hours it just keep redeveloping with rainfall rates of 1-3"/ hr there has to be some major issues around them and the NW side of Bmore.

Would love to see the totals that come out of this one for them. Couple weeks ago it was frederick now back to ellicott city like they experienced 2 years ago.

What a difference 24 hours makes. Hazy hot and sweltering humidity yesterday, cool, cloudy and very breezy, temps in 50's today. Strong ENE flow, sustained @ 20 mph and gusts approaching 40mph since this morning. Got about 1.5" rain this morning. Front, kind of a back door front, has pushed the heavy stuff south and actually will protect SNE/NMA for next couple days as it is deflecting Alberto to the west in the short term clearly seen on the 3K loop.

Alberto may be an interesting one to watch in a couple days. Gotta see how things play out with this front and the ridging still across the area. Forward motion will be a huge influence on what exactly happens with it.

I haven't looked at the projected paths / models in a few days but last time I looked the GFS had Alberto meandering around the continent for like 10 days. Up to Canada and back down the east coast to Georgia and then returning up the coast as a Nor' Easter. There really isn't anything substantial to pick it up or kick it out at least in the 5-8 day time frame except for the occasional front coming down from Canada to alter its course. So yes there are locations that will see copious amounts of rain where ever this thing decides to go and unfortunately could keep us here in SNE in the cool cloudy weather for an extended period.

The radar was ridiculous this morning in central, err I mean southern NJ. That band just blewup in an hours time and sat there for its morning coffee for hours. The storms offshore were very impressive as well as the disturbance really blew up once it stepped off the coast.

Just incredible rains just NW of the airport we have managed just under 2" from our ground obs asos a little bit away has less but reports of close to 10" of rain in 3 hours.

The videos coming out of there are insane. Gonna be a bumpy ride getting home later.

That looks to have last updated at 1830 at just over 24 feet. (new record).
It was updating every 15 min, and now it is not.....
