Hurricane Agnes

RER tweet from Mt. Holly -

And another flizzard blob overhead. Temp down to 25 with dp 18. Also had a bunch of RERs today for coldest max for the date (Philly may have just missed it or tied it last I checked) -

And getting some more although the sun is out too... Temp 27 dp 15.

And another flizzard has appeared. Temp 28 dp 15.

EAS issued over me...

Getting another flizzard. Temp 29 with dp 11.

New Snow Squall Warning issued south of me across the western 'burbs and through west/central Philly and into Jersey - Sun back out here and temp back up to 31 with d 11.

Took all day but am finally getting a flizzard with blowing snow. Temp is 28 and dp 12.

Another Snow Squall Warning Eastern Montco/Bucks and into Jersey -

Have some returns over me down here but not seeing anything. Temp is 30 with dp 12.

Multiple Snow Squall Warnings issued for Berks, Central Montco & Bucks - (about to expire) -

That was pretty serious cold here and I bottomed out at 22 at 6:45 am this morning. The winds never went calm overnight so that was pure cold air and not even radiational cooling. The dp dropped down to as low as 2. I know the blooms on star magnolia not far from me are or will probably be mush (although it had been blooming for about a week already). It's currently partly cloudy with lots of cumulus and the temp has recovered to 29 with dp now up to 10.

Just posted by Mt. Holly -

Polar Vortex weakening. It has been very strong much of the winter and stayed put, which is not that common for such an extended period in general... but then the stratospheric warming began - https://www.severe-weather.eu/global-weather/strong-polar-vortex-warming-collapse-event-forecast-spring-2022-usa-europe-fa/ leading to this - https://www.severe-weather.eu/global-weather/polar-vortex-2022-dramatic-arctic-cold-season-return-united-states-canada-mk/

Mt. Holly had a climatology section in their AFD this morning that included the Monday March 28 record low max temps for the area -

Nothing here although I am under a radar hole with the sun peeping out from the cloud deck. Temp has been wavering today where I hit a high of 43 just before 11 am (after a low of 36 earlier this morning) but am down to 40 with dp 29. My sis in Upper Darby texted about seeing some flurries down her way.

Some thoughts from Mt. Holly this morning about the unsettled weather - Talk about a mixed bag! I know KYW reported a brief snow shower downtown earlier. I haven't seen anything here other than the light rain I had earlier this morning. Currently changeable skies and 49 with dp 33.

Here were some of the reports earlier in both Bucks and Montco of the graupel (including indicating it was enough to accumulate to at least a coating).

NBC10's Krystal Klei (on KYW) was noting that N/W of Philly there were reports of graupel so that may be what it was, particularly due to the warmer surface temps. Other than a passing light shower before noon that deposited 0.01", It's been mostly unsettled here today with the sun in and out and a high (so far) of 54, after a low of 45. Currently mostly cloudy, with the sun coming in and out, and 50 with dp down to 30 with I'm guessing what is some CAA drying things up. ETA - traffic guy (Andy Anderson) on KYW in shock reporting what he said appears to be snow in the traffic cams (and the anchor Ellen Kolodziej confirmed looking out her window downtown at 24th & Market - she just said it was like "snow in Southtown" from the Christmas cartoon).

Stratus has lifted, sun is out with some scattered clouds (more clouds towards the N/E) with temp and dp 48.

Some kind of convection came through here overnight between 9 - 10 pm, triggering the lightning detector. Ended up with an additional 0.13" of rain during that round for a total of 0.62" for the day, and along with another 0.02" early this morning, yields a 3-day total of 0.81". Currently misty and 43 with dp 43.

Ended up Wednesday with a high of 51 after a low of 40, and 0.17" in the bucket. Today I had a low of 41 and only managed to get to 46, which is my current temp at post time, and it's overcast/misty, with another 0.49" in the bucket (2-day event total so far = 0.66").

Ended up with a high of 62 and low of 49 yesterday, followed by a cooler high of 59 today after a low of 43 this morning. Currently 50 with dp a dry 23, but know some precip is due the next couple days. Will see if the progged amounts verify (although this is over 2 days) -

I was one of those kids (in 7th grade at the time) going to the train station everyday (on one of the Chestnut Hill train lines - which was transitioning from Penn Central/Conrail) to go downtown and then get on a SEPTA bus (which itself had been transitioning from PTC) the rest of the way to school - in the dark, in the mornings during late fall/winter, after Nixon signed the last ridiculous "all-year daylight savings time" bill, in effect from January '74 until October '75 (ending my freshman year in high school) when someone finally got some sense knocked into them. And yes I needed the flashlight in the mornings during the 2 winters this covered since my route to the train station was on a little residential street that was poorly lit by today's standards (this was before those "pinkish/yellowish" HPS street lights were installed around the city). And the actual path from the street to the station was even worse in terms of lack of maintained pedestrian lighting... I used to catch what they called the "7:40 Express" that got me downtown at around 8 am and it was only then that the sky was trying to brighten and the sun was thinking of rising, but not actually up yet until we were getting closer to March.
