Hurricane Agnes

Seems the precip is behind the front. Harrisburg has been apparently getting it (was scanning some webcams over in that area).

Here is a more recent zoom-in.

If Newman is correct, it may be that the radar is not picking up the low-top portions. There's a solid "something" in a line between Lancaster and Reading.

It's already 29 IMBY (30 @ KPHL and 2 @ KAGC) so will see what happens! I've driven through some nasty squalls here in Philly (although it's been awhile).

Since the temps here are relatively "warm" compared to the back side of it, I expect it would intensify as it approaches since this is happening during the heating of the day... maybe doing some downslope "warming" (relative) on its way in too.

I was literally just looking for it myself on the radar and nada! Makes sense.

The warning itself is relatively new (phase-in of it started a year ago in certain FOs, although not here)! https://www.weather.gov/media/nwr/Snow Squall_WRN_NWREAS_112117.pdf Will be interesting to see if it holds together and is able to meet the criteria for Mt. Holly to issue one in our CWA.

Bottomed out at 16 this morning (about an hour ago) and currently 18 and clear.

Temp has continued to drop from a high of 27 since midnight. Down to 18 now at post time. Light breezes that kept up overnight have precluded any radiational cooling so far.

Pretty much done now. Finished up with a slushy (and now melting) 0.1" (and 0.17" rain). Temp is down to 33.

Now starting to get a coating on the coldest surfaces (e.g., car windshields, untreated paved areas). Temp continues above freezing at 34.

Last bit of SN- mixed with some rain coming through now. Temp still 34 with no accumulation.

Getting some stray flakes now. Temp still holding at 34 with no accumulation. Rain in the gauge up to 0.17".

That was that damn ice storm month when the tristate area ran out of road salt (they sent caravans of trucks down from NY to try to restock this area) and stores ran out of consumer halite/ice melt. I'm not sure what the Neshaminy Creek did a few years later in '96 during a similar warm-up but the '96 warm-up came after that record 30+" of snow and included quite a bit of rain too. If the gazebo had survived '94, it might have been swept way in '96. I remember in that latter case, the Schuylkill river was so swollen that a huge tree trunk got wedged near the top of an arch on an old stone railroad bridge that went over the river. Back then, I commuted to work every day on either of the river drives and noted that the tree trunk stayed there for months and months before they finally removed it.

Temp has been holding at 34 for the past hour or so. Currently getting some drizzle (not seeing any flakes and no accumulation anywhere here in NW Philly yet). Rain up to 0.15" so far. Looks like the back edge is around Lancaster now.

Now getting some snow mixing in with the rain and also some fog. Temp down to 34 and still falling. Rain/snow line is bouncing around the western borders of the city.

Temp is down to 35 here now and still getting rain although some might be white rain (hard to tell). Up to 0.14" rain.

Just popped back in from flipping my car wipers up but currently 39 here with temp starting to creep down and rain. Up to 0.11" of rain so far. Rain/snow line is moving this way from the NW though. Edit - just ticked down to 38.

Currently holding at 40 with RA (not enough to tip the bucket yet). Meanwhile KINL is currently -20 with a forecast low of -40. Edit - just tipped at 0.01".

Temp up to 40 here. Radar showing returns over the area but nothing is reaching the ground.

38 here too and it's overcast (rain/snow line steadily moving in from the SE).

Mood flakes have graduated to pixie dust that is starting to moisten the asphalt a bit (zero stickage). Temp up to 34.

Just started getting some mood flakes. Temp still 33 but dp has gone up to 21.

It never reached freezing here at all yesterday during the daytime after the temp fell from a high of 35 at midnight, but currently 33 now at post time and overcast.

Yup. Agree. Squalls can really produce. Will be interesting to see if it will meet the criteria of the new "Snow Squall Warning" in the I-95 corridor.
