January 25-26 Winter Storm Potential

[Ralph Wiggum]

Winds are picking up here out of the N,NNE...lots of blowing around of the snow.

[Fields27]

3.25" as of 8am. Cleared the board, we will see what this next hour has in store.

3.3" as of 8am here in EN temp down to 8.7 above

Hopefully those rates can slow down that warm nose. That mix line is knocking on Baltimores' door and racing N.

Great news! Eyeballing about 3-4 inches OTG in Spring Twp 

[RU848789]

As of 8:00 am 2.6" otg at 11F, so 0.6" the last 30 min - can't imagine not making it to at least 8" with at least 5 hours of >1"/hr rates before any changeover (and hopefully the changeover is after that and rates are more than 1" per hour until then).  Started around 5 am.  

[Newman]

3.75" already in Fleetwood (per family). Rates have been ~1.25 in/hr or so

Looks like Mt. Holly just slightly lowered snow totals

NWS maps hard to follow these days. This is a weird range map at odds with the colors, plus it starts at 7 am, so it's not the event map, which is below, starting at 4 am, so I don't think they cut amounts.  Wish they'd only issue event maps - users can look and compare to what they have so far. 

[21chuck]

Snowing moderately with 2.8" in south philly. I saw DC has been taken over by sleet with these heaviest bands. Anyone recall when they were forecast to transition? I thought it was around 10 am. 

[Physicsteve]

Yeah that top ‘experimental’ one has me in the helpful 3-9” range. No difference in impacts there… Needs to go back into the lab.

Same here 12f dew point 11f heavy snow blowing and drifting happening around the cars etc. 

Getting hard to measure here snow blowing around.

I would say 4” drifts are like 6-7” 

[Newman]

This is the warmest the 12z HRRR gets at KABE. If this is the case, you'll probably mix with sleet, not do a full change over. Under heavy rates you might flip back and forth between all snow, and a snow/sleet mix. So ratios will be more like 6:1 or 7:1 vs a pure sleet 3:1.

Don't remember if that’s when they were just hoping or actually progged, but I remember that time being bandied about

Wonder if it's an AI test run?  Will see what verifies!

Do you still plow West Bethlehem or are you in a different section of the city?

[JTA66]

So what is the verdict? Shovel/snowblow before the change or will that just make surfaces worse with ice? This mess should be light enough that a crust on top *shouldnt* make it too difficult or jam the snowblower. What are you guys doing?

Adam Joseph said don’t shovel.

Deanna Durante said to shovel in stages.

Wating for Fred Schropshire to weigh in.

[Birds~69]

Heavier stuff from the SW moving in...

10F/mod snow

 

[RU848789]

Here's a PSA for snowfall measurement: clear the board after the change to sleet and sum the snow and sleet measurements together; otherwise you'll likely get some compaction.  This is from a great article on snow measurement in The Conversation based on NWS guidelines.  Or maybe we'll get lucky and get no sleet, lol.  

More complicated cases of measurement
So, let’s consider three common scenarios. Here in the eastern U.S., we often have to deal with snow that changes to rain during the course of a storm. Imagine 6.0 inches (15 cm) of snow falls, then an inch (2.5 cm) of sleet which compacts the snow to a 4-inch (10-cm) depth. Then, on top of that falls an inch of freezing rain which further compacts the snow to 2.6-inch (6.6-cm) depth by the end of the observation period. What should be listed as the daily snowfall? The snow depth?

In this situation, when the snow transitions to sleet, the snow board should be cleared and the maximum depth of snow recorded – 6 inches (15 cm) in this case. Do the same with the sleet and this will add an inch (2.5 cm) to the snowfall – technically, “solid precipitation” – total. Freezing rain is never added to the daily snowfall total because it is in liquid form when it reaches the ground. Thus, the daily snowfall is 7.0 inches (measured to the nearest tenth of an inch) (17.8 cm), while the snow depth at observation is rounded up from 2.6 inches (6.6 cm) to 3 inches (7.6 cm).

Yes west, out in the avenues , that’s broad and 7th I believe in the pic

[Chadzachadam]

3.5” in NW Philly. Looks very different from previous storms with basically nothing on the trees.

Seems from other threads like the sleet line is coming quick but that sleet is holding on strong and not changing to ZR as fast as modeled. Most of NC and SC still primarily sleet

[The Iceman]

3” on the snow board at 9 am in Levittown 

snow growth still isn’t great and we are definitely getting drifting now and stuff blowing off the roof. 

[Ralph Wiggum]

Looks like the low is right on the coast of N NC. More of an easterly component here now ENE breeze with blowing fluff. 10F

[Physicsteve]

Heavier echoes inbound about 10 minutes from now, and cc radar looks clean. Let’s thump. 

[snowwors2]

5.2” @ 9am

Cool. The avenues were my old stomping grounds. Lived at 2nd Ave and Union Blvd from 1973 to 1982, then 10th and Market from 1982 to 1988.

Can’t we all just go outside and blow in an east southeast direction to blow the warm tongue further east and send the storm down on the NC eastward locking in out cold got 18-22”
