Hurricane Agnes

18z GFS ice and ZR snapshots.

For the end of month (Feb. 28 - Mar. 1) storm - the 12z EC has an over-running storm with a cold front/LE-looking finish where the GFS has no such storm at all except as something that slides along the STJ and out to sea.

6z GFS ZR verbatum is ugly for I95 corridor vs 0z EC that throws that threat to the north.

6z GFS still has the colder solution but the sleet/ZR bomb shows up on the 0z EC and Canadian.

I was at my sister's house for my niece's bday party in Wyndmoor when it blew through down here between ~2:30 - 3 pm (I live a couple miles SE of her). My other niece was driving down from N. Jersey and said she got caught in it up there coming down 95 and almost pulled over. There was no accumulation in this area but a definite flizzard nonetheless. The temps appeared to crash to ~32 or so IMBY (after a high of 43), before recovering to about 36 or so and then went on with a regular diurnal cooling as the colder air trickled in and the sun set. The dp started dropping just before the temp crash and did its own crash during the brief temporary temp recovery. Currently 23 and clear (saw the big just-past-full-moon rising on the way home) with dp 4.

Looks pretty intense on radar! It was dark briefly here between noon and 1 pm but at the time the temp was bopping between 39 and 40. Didn't see any precip. during that time. It's currently 41 here.

Snow Squall Warning in Berks/N. Montco -

My final low yesterday was 28 just before midnight after a high of 62. This morning I bottomed out at 23 and am currently mostly sunny and up to 31 with dp 21.

6z GFS and 0z EC for the potential mix storm Feb. 25 - 26 (edited to add the Canadian).

Temp has dropped further to 42, dp 33, a changeable sky with the sun trying to poke out, and gusty winds.

Now down to 48 but what took the faster hit was the dp, which is now down to 37.

KPNE had a 52 mph gust too! I had an initial drop from 62 to 57 and it has sortof leveled out at 57.

KPHL reported a 56 mph gust.

STS issued - (a bit late because the line is past here)

Fast moving line and it is past me now with a max of about 0.66"/hr rates but dropping. Currently have 0.20" in the bucket and the winds are definitely picking up. Temp is dropping as well and now down to 59.

Starting to get the heavy rain now from the line ahead of the front. Temp 62 with dp 60.

The line appears to be forming segments. Currently breezy and 62 with dp 60.

Mt Holly's analysis of the expected wind event today -

Diurnal low was just after midnight and am now back up to 61, with dp 59 in anticipation of a roller coaster non-diurnal temperature change day. Had 0.13" yesterday and am currently at 0.09" at post time.

SPC has the area in their SWDY1 for Thunderstorms -

Yup - so far, 3 RERs issued (Philly, Reading, Wilmington) -

Looks like I topped out at 65. So far KPHL has tied the record (68F). Currently overcast, stormy-looking and 64 with dp 52. I did see this mention from Mt. Holly about "wet" walks that might have been observed this morning and that answered my question wondering about that since I experienced it here - here

Am now up to 62, partly sunny and breezy, with dp 51. Definitely a huge change from the weekend!

Bottomed out at 41 this morning and am off to the races at 56 at post time, with dp 49 and overcast with a thick layer of high clouds. And yup, the area is under a Wind Advisory. I also saw that Mt. Holly mentioned some records that might be challenged today (also saw it mentioned in the AFT Climo section) -

Had a low of 23 this morning but once the sun was up, the temp began that fast climb until I hit 48 as a high. The south/west-facing snow is pretty much gone but there are still patches on the grassy areas that are more in protected locations and are north/east-facing. The plowed mounds have held their ground though, but with the shrinkage more pronounced. My snowdrops are in full bloom and I did catch a glimpse of the setting Full Snow Moon early this morning. Currently 43 with dp 36 and some persistent high clouds.
