Hurricane Agnes

Getting moderate rain, just over 1/4"/hr - 1/3"/hr but nothing extra windy beyond what has been going on the past couple hours. Looks like the line broke up over me. Not picking up any convection either. Have 0.25" total in the bucket so far. Temp is 60 with dp 59.

STS issued.

Looks like the convective line is reforming as it is approaching the area. Am getting some light rain here (had 0.10" earlier this morning from the morning round) and am now up to 0.12" for the event so far. Temp is 62 with dp 59.

There's a Wind Advisory up for the entire state and I have been watching the line as it moves across and it looks like it has diminished a bit but then it might do its final downsloping as it approaches the area by maybe midnight, and re-fire into a stronger line. SPC DY1 has us still as "marginal" - And I agree that it has been pretty gusty the past couple hours but the temps have held in the mid-60s too. It's currently 64 with dp a juicy 61.

Handful of RERs so far - My high so far today has been 64 and it stayed overcast the entire day, so no sun to heat it up. It's currently 64 and overcast with dp 60.

Still overcast here but temp is up to 62 with dp 59. You can see the convective line just west of Pittsburgh with some antecedent band...

Got some dense fog here early this morning (vis. ~1/10th of a mile) until now, when it's starting to lift with the temps increasing. Low was 44 around 3 am and temps have been rising since. Currently overcast with stratus and mist and 55, with dp 54.

SPC put the area in a marginal risk for DY2 -

Maybe reflecting that the NAO is progged to go neutral or slightly negative in the long term (10 - 14 days).

All kinds of stuff could happen with those squall lines. It will probably depend on how much heating is able to occur before the front arrives. More often than not, I have seen the cool air "bleed in" and stabilize the atmosphere around these parts (MBY at the higher elevations) but when it jumps over the river, all hell can break loose with the down slope.

Interestingly enough, we see this sort of thing more in the spring than the fall but it's basically the same sort of dynamics (although for somewhat opposite reasons for those 2 seasons). I.e., spring has cold ground and warm air influxes and fall has warm ground and cold air influxes. Mother nature dictates that the temp/pressure must come into equilibrium somehow. I did see there was a tornado threat in the TN area. Currently overcast here and 38 with dp continuing to rise and at 32.

He mistakenly mixed you up with Dennis Nedry - But then all the Wayne Knights look alike so....

Wind Advisory lofted for Philly metro, as well as well north/south and east- Have so far had my low of 32 happen some time after 1 am and have been on the upswing since. Currently 36 with dp on the rise and currently at 30.

Am a bit surprised but probably shouldn't be, that it stayed a bit colder here today than I expected. The low was 29 and high was 39 but we are closing in on the shortest days of the year... Even with the low dews through the day, am expecting the WAA to start coming soon though. Currently 36 with a dry dp 25. Did have a red sunset, so I guess that means something (maybe RedSky smiling at the brief but unexpected white stuff).

I thought the above was your "final word" but apparently not. Philadelphia is the 2nd largest city by population on the east coast. Full stop. Enough of the bullshit.

Mt. Holly did a little ditty on December snow here - Coin flips (or probably something to do with ENSO states).

You may have to host it somewhere and link to it or find a way to shrink/compress the size (maybe get it down to a lower resolution or edit it to run for a shorter amount of time). I know the different subscriptions here offer different file sizes permitted for each upload.

You guys made me get up and check and there be white pancakes coming from the sky! Temp at 37 but dp is up to 30 so the atmosphere has moistened enough to kill the virga.

Looks like upper Bucks got under something. Grabbed a snapshot of a heavier band not far from you... RedSky should be under some good stuff. It's too warm here (am at 37, although the dp is now up to 29).

That's not how they do "normal" temperatures. The climatology to determine what is "normal" is done over a period of many years. They may report out an "average" temp for the day as a somewhat meaningless stat, but they generally average the daily highs for each season over some period of years, and then do the same for the lows, and with that in hand, can come up with what might be considered typical ("normal" ). Similarly, USDA had been calculating their hardiness zones by averaging the lowest min winter temperature for each year over a period of from 15 - 30 years for different regions of the country and will then assign hardiness zones based on that to give gardeners some idea for what types of plants (trees, shrubs, etc) can be grown in different areas and have a good chance to survive the lowest temps (the zones designated on a 10 degree scale).

Just a couple weeks too soon.

So you did see something crystalline fall from the sky that wasn't something like ashes flittering your way from someone's fireplace. Meanwhile the sun has busted out here through an eroding deck of high clouds. Temp is up to 39 and dp is 25.

It's a shame that I didn't think to pull up my GR2Analyst (on a different laptop) to get a finer resolution from the Level 2 data to see if I could capture that time frame. Definitely won't rule out a mass exodus of starlings or those damn Canada geese (although if it were them they might have ended up on this side of the river)!

I've seen radar captures of sudden bird (or even insect) migrations. But this seemed to also cover a broader area in addition to what was centralized near Mt. Holly. Was looking again at the radar and a map again and it's possible there was something going on at Joint Base McGuire–Dix–Lakehurst (looks like that is probably what is closest to where that blew up).

I remember years ago before coming to this site, when there might have been a signal like that because we ended up with a sleet storm on Christmas Eve and I remember driving my mom to church services for the evening mass.
