Hurricane Agnes

You made me look out and check the station - yup rain is back. Another 0.08" here from light rain, for a total of 1.65" so far. Temp is up to 63.

Looks like round 1 is about done here. Ended up with 1.57" of rain. Currently 61 and misty. I believe the next step is warming once the warm front lifts to the north, and then the coming of the cold front (with winds really picking up during the day and into the evening). Am guessing wherever that triple point goes, so lands the worst of it.

I think there are 2 more events to come - lifting of a warm front (with associated precip) and then the arrival of the strong cold front with the possible severe thunderstorms later this afternoon I think.

Now up to 1.38" of rain and temp up to 61, with light rain at the moment and breezy. Looks like this round 1 may be ending soon, with the next rounds to come later today.

After 0.01" rain just before midnight yesterday (total precip for yesterday), am up to 1.12" this morning and coming down at a good clip - the heaviest being the past couple hours or so. The winds have started to pick up now too. Current temp is 59 with variable / light - moderate rain.

High Wind Warning... Was a degree warmer for a low here this morning compared to yesterday (36 vs 35) and it took a bit for the temps to creep up from that with the overcast that comes and goes with breaks of sun, but currently 66 and warming nicely now.

Both my sisters (in Delco and Montco) texted about getting flurries. I jumped up and opened the door and saw a flurry.

Under the diffuse 2nd line. More wind and overcast but nothing convective. Temp at 56.

Sun came out briefly here but it has clouded up again and I see a foreboding line to the west. It'll probably be even more meh than what I got from the 1st line but it'll probably be a bookend to this part of the event. Temp is down to 55 now (11 degree drop)!

There's a dryslot and another possible line after that headed east (if it holds together).

Updated Warning (temp here down to 62) -

Sortof meh. Didn't see any lightning although heard a distant thunder earlier. The line broke up around the hills here but can hear a roar to the east of me. The temp is dropping and you can feel to cool air coming in. Temp down to 65 and dropping with some rain. ETA, temp down to 64 and continuing to drop.

Starting to get the winds. Temp up to 66.

LOL @ the real life expletives.

Warning issued further east to Philly metro -

The previously broken line has consolidated pretty well!

Current temp here is 65 and the skies have been variable with clouds moving in and out, with frequent breaks of sun, since the little line of rain came through earlier this morning (no measurable here from that).

Severe Thunderstorm Warning lofted for N/W of Philly metro -

SPC lofted a Severe Thunderstorm Watch for the area -

They let you trial it for 3 weeks and then you'd have to decide to go on and buy or not - http://www.grlevelx.com/grlevel3_2/ Although I haven't had chance to play around with customizing it, it does let you put up multiple panels of different radar parameters. Will be interesting to see if an advisory is lofted for Thursday and/or Friday (most likely). I know they were talking about possible frost for some areas...

That image is from GRLevel3 v2 (I also have GR2Analyst on a different (convertible) laptop, and that is pricey but cool because of the volume view to look at cells... and I do like that the best but it is probably not practical for just occasional use). When I was still upstairs early this morning, I popped open what many here use for mobile - RadarScope - that I have on my phone and that was sufficient, with good resolution, although I expect that the "Pro" version might be better (in terms of archived data) and could get me closer to the Gibson products.

I had signed up for "CodeRED" for PA's ready.gov notifications and OMG at 2:30 am, all hell broke loose in the house with everything (weather radio, texts, actual phone calls on my cells) - and then about 10 minutes later, the storms came. It's been a long time but it was almost continuous lightning (with some thunder), with almost 1"/hr rain rates at ~3 am. I ended up finally coming downstairs and looking at my radar programs and capturing snapshots. Didn't even bother going back to bed. Ended up with 0.58" of rain after that. It was pretty much gone by 6 am. I was surprised that the high for the day was actually warmer here yesterday (68) than Monday (64). Currently partly cloudy, 59 and juicy out, with dews in the upper 50s.

It's also possible a couple big volcanic eruptions could offset some of the drop in vehicle emissions. One thing's for sure - if the rain every couple days pattern continues this spring, there will be a much-reduced chance of any massive triple-digit heatwaves this summer.

Have been watching that as it blasted into South Philly, strung itself out, and then reformed on the other side of the river.
