I'd think areas under that heavy band earlier had to have recorded at least .5-1 more than they got out at the airport but that's pure speculation.

Overall, looks like the heaviest is now behind us, just some light to moderate showers now but you can see the back edge quickly approaching into eastern OH.

I made it to work this morning, I'd say I was on Washing Blvd around 6am and it was pouring but still passable and open. If that had been closed when I went to go through I was just going to turn around and go home. As I made it further South and passed Kennywood it was a very light rain and almost no issues. Sort of the opposite of what I expected, figured it would get worse the further South, but it looks like from the City NE is getting slammed right now. Probably had I left an hour later it would be a different story.

Gotcha, yeah I didn't take into account the timing of your post vs the models I was looking at. The worst is still SE of Pittsburgh and although it seems like whatever the trend is in the last 12-18 hours continues until game time I don't see guidance being the far off but if there are any convective components to the rainfall that will through another variable into the mix. That line moving through now will saturate the ground before the main event for sure. I was hoping to have some clarity, my commute in takes me through various flood prone areas so it would have been nice to make the call on whether to just stay home tomorrow. Last thing I want is to get detoured or stuck on Washington Blvd.

I was thinking the opposite after reviewing 12z models, most seemed to have nudged a bit North. NWS put out a solid discussion pertaining the upcoming situation. .SYNOPSIS... The remnants of Hurricane Ida will bring heavy rainfall and potentially significant flood impacts to the Upper Ohio Valley tonight into Wednesday. Cooler, drier air is expected after the system passes Wednesday night. && .NEAR TERM /THROUGH WEDNESDAY/... Regional radar imagery shows a line of showers developing and strengthening in area of modest CAPE (~500 J/kg) and along/near a diffuse frontal boundary stretching along and just north of I-70. With rainfall rates of up to 2 inches per hour possible, any training segments will pose a flash flood risk. Total amounts in the highest areas will likely be in the vicinity of 2 inches per HREF probabilities, effectively saturating the ground in those areas before tomorrow`s rainfall. This convection should wane towards dusk. Attention then turns to the remnants of Ida and a potentially significant flood event for the Upper Ohio Valley into the Allegheny Mountains. Ida is forecast to move into Appalachia Tuesday night before heading off the Mid-Atlantic coast on Wednesday. Very high moisture content associated with Ida will surge northward into the Upper Ohio Valley along a strengthening frontal/baroclinic zone that will lie right across the forecast area. Strong frontogenetical and isentropic lift in the frontal zone in the right entrance region of the northern stream jet will allow for a band of moderate-to-heavy rainfall to develop and persist across the area. Run-over-run model guidance has been consistent with placing the axis of heaviest rainfall in an area stretching from the Mon Valley to areas northeastward such as Uniontown and Connellsville and then into the Laurel Highlands. 24- hour totals ending 8PM Wednesday look to be around or possibly in excess of 6 inches in this heaviest axis, with rainfall totals dropping off fairly precipitously to north and west. The greatest uncertainty in the rainfall forecast will be across the rainfall gradient , which will encompass the immediate Pittsburgh metro area. HREF probabilities suggest rainfall amounts may be upwards of 4 inches towards the southern portion of Allegheny County, dropping significantly to perhaps just around 1 inch towards the Beaver County border. No changes are currently planned for the flash flood watch. Officially the watch begins at 2am, though rain is expected to begin before that. Wouldn`t rule out a warning or two today with afternoon convection or this evening as the initiate wave of Ida rainfall approaches the area. As far as impacts, we`re anticipating a somewhat similar scenario to significant tropical systems of the past such as Gordon (2018) or even Francis/Ivan (2014). The similarities exist within rainfall totals and duration, though the axis of heaviest rainfall will likely be slightly farther southeast than it occurred with Francis or Ivan. This will cause significant rises in the Monongahela River and its tributaries such as the Youghiogheny and Cheat Rivers. Additionally, flash flooding is likely in those surrounding areas with many smaller streams likely going to exceed bankful. If you live in a flood prone area, please have an emergency plan in place and methods for receiving warning information. Rainfall should begin to exit eastern Ohio and NW PA by noon Wednesday, eventually exiting the entire Pittsburgh forecast area by tomorrow evening once Ida shifts off and cool, drier air ensues.

Latest trends do seem to have shifted SE with the track and expanse of the heaviest rain. That map looks like so many Winter Storms over the past several years it almost triggers some PTSD lol. Only this time I’ll be fine getting fringed, 1-2 inches will be much more manageable and another tick SE puts most of the city out of significant impact.

Yeah it's hard to say what to "root" for on this in terms of mitigating impacts. Hopefully some of those rain amounts are overdone at this range. 4-5 inches in an 18-24 hour period will no doubt cause some problems.

Interesting watching the radar this morning. Not often you can see a clearly defined center of circulation from a tropical storm / remnants moving right towards us.

Yeah, I'm ready for this pattern to break for a long dry spell. Pool needs drained every other day and my backyard fill project on hold because it's just so muddy. One good thing I guess, the garden is going crazy.

At work, but I heard 3 rumbles of Thunder! wohoo

That's interesting, I hadn't checked the records / realized May 9th had that many cold records.

I just hope when this pattern ends we don't shoot right into mid 80s and humidity. Average May weather is pretty enjoyable so it does suck to be so cool right now. On the other hand, it wouldn't have taken much to be slightly colder to break some May snowfall records today. If it's going to be 40 and rain may as well be 35 and snow in my opinion and make it interesting.

Just sprinkles so far imby today. Think I've only heard thunder once this Spring which is unusual.

Yeah that was a heck of a night here... Phones went off with the warning and woke us up, my wife was like should we be worried, I looked outside and saw the rain going horizontal as the radar loaded on my phone and yelled yes get the kids and let's get in the basement. We could hear patio furniture sliding across the deck. We were without power for a solid 12 hours afterwards. Luckily no damage other than a destroyed trampoline. I remember being glad I had a dying 80 ft locust tree near the house cut down 2 weeks earlier. Wouldn't mind some thunderstorms either but can do without the tornado.

Maybe last snow of the season on tap. I say bring it on, unrelenting summer heat will set in soon for a good 3-4 months either way.
