Hurricane Agnes

Blast from the past! As an obs, that hazy sky capped my high to 82 today (at least so far) and it's currently a partly sunny and hazy 81 with dp 61.

There is some discussion of it back in 2012 before it got near here, right in this forum , starting around here -

When I was looking for the actual number of miles that defined one, I had found the article about what you are talking about - https://wchstv.com/news/local/thursday-marks-11th-anniversary-of-2012-derecho ETA - NWS write up on it - https://www.weather.gov/lwx/20120629svrwx

At least based on spotter reports, this probably is a derecho and today is supposedly the anniversary of the 2012 one.

Those "Air Quality Alerts" are like how they did those old "Homeland Security Advisories" - In any case, my temp is now up to 74 and the dp is 64, with hazy skies. And as a sidenote, I had a fledgling robin out on my back patio steps late yesterday afternoon, with a mama feeding it just as I opened the door. The mama was incensed , cursed me out in "robin-screech", and flew to a nearby tree. I still had to go out there so stepped around it to do what I needed to do and came back in. Haven't checked this morning to see if it was still out there.

Those "codes" that you are talking about are what the "Delaware Valley Regional Planning Commission" uses to issue their "Alerts" (they are a general alert "type" that doesn't get granular) - That is different from the color-coding used by EPA with their "AirNow" site (and any used for other air quality sensors/monitors), which actually gets into the weeds with PM 2.5 particle amounts. I also have an indoor PM 2.5, PM 10, and CO2 monitor that measures those readings inside (yes geek ).

Yeah the graph is just color-coded ranges and that bottom number is reflected in it. But I only mentioned because of how mine is doing ''color coding". I know it's not a pro device but it is supposed to be a decent amateur one and is one of a number of others (a popular one being "PurpleAir") where some have talked about correction factors and whatnot as compared to AirNow (e.g., one discussion about PurpleAir vs AirNow -https://thebolditalic.com/understanding-purpleair-vs-airnow-gov-measurements-of-wood-smoke-pollution-562923a55226). (and to clarify - the top image is my own sensor - an Ambient PM 2.5 out on my patio) Edit to add a wow on mine (and the 8am AirNow)!

Bottomed out at 60 this morning and it's currently 70 with dp a little lower than the past couple days, at 63. PM 2.5 (localized) is creeping up! I know different sources use different ranges for color-coding so at least for my Ambient PM 2.5, it listed this -

Wow. I had noticed the alert went up and actually saw that it wasn't the usual "orange" one but was a "red" one. Was at the supermarket a couple hours ago and the smoke hadn't quite gotten here but it is hazy here now. I recently bought a (replacement) PM 2.5 meter for outside and it has been creeping up. The humidity hasn't gone down much either and it is pretty muggy out. Currently hazy and 79 with dp 68.

They posted a PNS for the assessment of 2 tornadoes but neither there - I know sometimes it can be difficult to pick out a tornado if rain-enshrouded but I expect they go by both radar-indicated and nearby spotters. You can go through the LSRs for 6/26 - 6/27 here to see if there are any from your area - https://www.weather.gov/wrh/TextProduct?product=lsrphi As an obs, there is a strange orb in the sky that I haven't seen much of the past couple days that was not trying to peep out between a deck of clouds. I bottomed out at 64 this morning and am currently at 73 with dp 69.

With this latest round now moving past, so far I have 1.21" for the day (0.75" from that last round). That comes out to 5.04" in the past 5 days and 7.44" for the month of June. Currently damp and misty, with steamy windows, a temp of 67 and a dp of 66. There's another band back by Harrisburg and it will be interesting to see if that survives the trip to the east.

Rain has picked up here and is running ~1/4"/hr despite the sun wanting to come out. Currently have 1.17" in the bucket for the day (0.71" round 5), with temp 68 and dp 68.

After a pause, getting some regular backend rain and am up to 1.05" for the day (0.59" round 5). Temp/dp 67/67.

Now up to 1.01" for the day, with 0.55" from this latest round. Currently have lighter rain as it moves to the NE. Still getting lots of thunder and lightning.

Still have just under 2"/hr rates. Up to 0.98" (0.52" from round 5). Temp 68 dp 66.

Gully washer. >2.5"/hr rain. Under a negatively-tilted band. Total for today now up to 0.91".

Getting rain - shower with large drops. So far have 0.03" on top of the 0.46" from earlier (where I had gotten a 0.01" quick hit around 11 am).

Warnings up including over me. The sun did manage to get the temp up to 82 and it's currently getting dark with temp 79 and dp 71.

And not long after I posted that, the sun has popped out and the temp is creeping up. Now at 79 with dp 71.

I saw that line and was wondering if you were in the path! It's 77 here with dp a juicy 73 and am wondering if that will hold together as it moves east. Haven't had any sun bust out here although it looks like it wants to even if stuck behind the thick clouds.

The cold front hasn't even gotten here yet and with troughs and other stuff lingering around the area, all it needs is some sun fuel to get going again.

SPC's SWDY1 actually has part of the CWA in a Marginal Risk for today - Checked my data and so far for June, I have had 6.69" of rain (mostly in single/2-day events). Big difference from the 0.31" in May. Currently a mostly cloudy steamy windows day, with temp now up to 67 and dp 67.

Wissahickon supposedly reported out of its banks earlier. Still up there as of 5 am.

And Armageddon said "I'm not done yet", so between 3:15 - 3:45 am, round 4, complete with a sound and light show, appeared. Currently have 0.45" since 2 am from round 4, and that is on top of 0.47" from round 1, 0 from round 2, and 1.24" from round 3. Total over 2 days 2.16" at post time. Temp is 66 with dp 66.
