This is an absolute joke…!

How in the heck did MDT only record 2.0 inches of snow today at the 5 pm summary.

They had .42 of precip through 5 pm.

Did someone look out of the air traffic control tower & phone in to CTP & say, “it looks like 2 inches Bob”!?!??!

Hopefully this gets corrected on the official oversight daily summary. There is absolutely no darn way they had 2 inches of snow MDT on .42 of precip.

That may have been the total through 18z (1 PM).

The CTP website says daily climate summary as of 5 pm.

I see that you are a Meteorologist & your name sounds familiar. Do you work for the National Weather Service?

If you have any contacts at CTP, I would love to know if this is their official total for MDT or will they adjust it tonight with the final Daily Climate Summary overnight?

MDT measurement seems a little low...not sure it's that far off. I'm not that far away and only had a few extra tenths; however, my temp fluctuated between 31 and 32 while it snowed. Looks like MDT was running 33-34?

Yes, they were at 33 for much of the heavy snow. I would be ok with a little under 10-1, but 2.0 of snow on .42 of precip is less than 5-1 ratio.

A snow total with a 3 in front of it would understandable, but not a 2.0.

@Mount Joy Snowman @Superstorm one thing just struck me - one big failure on virtually every model was the predicted sharp contrast across the county. All of us ended up within a couple of tenths of an inch. Interesting.

Boy you ain’t kiddin. There was no battle; the warm air simply won out, as it so often does.

Been pretty much done with the heavier stuff back this way for the last couple hours, but have transitioned to freezing drizzle and some occasional pingers. Still just a hair under 28ºF. 6.2” was my reported total snowfall.

LOTS of snow chances on the 18Z GFS.  

I saw in the MA forum DT thinks the 18z Gfs is wrong next weekend and blocking will push the system further south threatening us. Then again, DT is in love with the Euro, sooooo.

I think the lesson I took away was the when the Nam twins are the snowiest model, they have a 98% chance of being wrong. When they are the warmest (in the winter with snowstorm threats), they are likely correct. Jmho

Speaking of reported totals, do you have any way to contact CTP to ask them about MDT’s snow total today?

I just love the active southern stream.  Kind of ignoring specifics outside this once coming in 3 days which is a damage threat I think.

Here's my latest update from Carlisle.  Around 5:30, after a half hour of mainly sleet, a transition to freezing rain took place.  Once that happened the temperature of 30.4 degrees began to slowly rise.  For the next 2 hours light freezing rain fell creating a very thin glaze on most surfaces.  I'll have a measurement a little later.  I'm estimating that around 0.10-0.15" of liquid fell.  At approximately 7:30 the temperature had risen to 32.0.  Since then the temp has only risen a small amount, stopping at 32.4 degrees.  I'll have a summary later this evening or tomorrow morning for the storm.

Fyi, I  love the 18z Eps. It had already turned to sleet imby BEFORE 1PM, yet the Eps 10:1 said I should expect almost 4" to fall after 1pm. Can't make this up. Eps are probably the most respected guidance, which is even more troubling. I'm sure it did ok for some, but it never seems to treat me right.

I just do not know how you can use an ensemble mean to forecast snow.  It is almost always going to be wrong imo.  Low resolution models all being fed alternate data.

Hey, Central PA Weather friends! I've been following what's going on and was hoping the Lancaster county crew would luck out and get more. This storm is a reminder of why I searched for a snowier destination. I can't believe you guys had less than a few inches of snow total last year. Geesh! Hopefully you can join in more on other systems this season.

Ok, let's use the Euro operational. 3-3.5"
