Blizzard of 93

MDT still reporting snow with .75 mile visibility at 4 pm. MDT has .33 of total precip through 4 pm today so far.

Moderate to heavy snow continues in Marysville. My 4 pm measurement was 4.2” snow.

Congrats

Warning level event verified for you. Congrats!

Latest HRRR still has good snow to go from the Harrisburg area to to north & west.

That line at the MD border looks impressive. I wish you well!

I’m at 3.1” in Marysville at 3 pm with moderate to occasional heavy snow with good flake size.

Great recent update from CTP “NEAR TERM /UNTIL 11 PM THIS EVENING/... *** Very heavy snowfall rates expected across the region for 3-4 hours this afternoon into early this evening *** Primary emphasis remains on a several hour period of very heavy snowfall rates of 1-2 inches per hour (and perhaps even 3 inches per hour rates for a brief time) progressing northeast across the CWA this afternoon and early this evening. Strong uvvel via a combination of WAA and FGEN forcing at the nose of a 40-50 kt south-serly LLJ and beneath the right entrance region of an upper lvl jet streak will support an approx 2-3 hour period of intense snowfall rates with still 0.5-1 inch per hour snowfall rates bracketing this period on both sides. That will be the bulk of the snowstorm. A quick- hitting intense variety that will make travel and plowing extremely difficult for those several hours. The period of heaviest snowfall for our SW Zones will conclude by 22Z, while the region from KBFD to KUNV and KMDT/KLNS will see the heaviest snow between 20Z and 00Z Sun, and 22Z Sat-02Z Sunday for KIPT and the Western Poconos. Vsbys in the heart of these time intervals will be as low as just a few hundred feet. 3-5 inches of snow has already fallen across the Laurel Highlands as of 19Z and there is another 2-3 hours of 1+ inch per hour snowfall rates ahead, with lingering lighter snow afterward. This will be representative of what we`ll see across the Central 2/3rds of the CWA later this afternoon and evening and our current forecast snow totals look in great shape. The toughest forecast remains close to the I-81 corridor in Scent PA where the max wet bulb aloft reaches 0C to +1 C. This slightly above freezing layer aloft may not be thick enough to support melting (usually need about +1-2C aloft to support a true changeover to sleet. What we may see is periods of significant snowflake aggregation and rapid accums of these larger flakes. We could easily see Warning Criteria snowfall of 5-8 inches over the northern 1/3 of York County with Advisory amounts of 3-4 inches in the southern part of the county with a similar occurrence NW to SE across Lancaster County. A very tough call with just how thick and how far NW the melting layer aloft will get. Temps at mid afternoon remain within a fairly tight 5 deg F range between 28 deg F (across much of the Central, NW Mtns and Laurel Highlands), to 31-33F over the Lower Susq Valley. Extrapolation of the back edge of the thicker, textured seeder feeder clouds (Moving NE at 45 KTS) will be near a KBFD to KUNV and KHGR line around 23Z and across the Susq Valley and points NE between 00-01Z Sunday. Snowfall rates will rapidly decrease afterward with some areas of -FZDZ possible, esp across the SE half of the state.”

Here is the 18z HRRR. Harrisburg area north & west still has good amount of snow to go according to this run.

Hopefully you flip back to get a little more snow when the rates pick back up. Radar is super juiced in MD & PA southern tier.

Best since 2021. Jan 31/Feb 1 MDT got around 10 inches of snow. This could be best for Harrisburg area since then.

MDT reporting Heavy snow at 2 pm with .25 mile visibility.

Same here in Marysville & the wind is picking up too.

Great to see the trends with next weekend’s potential. The modeling is responding to the block up top.

Good to see MDT reporting .5 Mike visibility with Snow at 1 pm … I am watching….

Latest HRRR is good for most.

CTP ramping up at game time!

Flake size & rates picked up in the last 30 minutes in Marysville. Roads caved & all surfaces covered. The good stuff is still over to my southwest.

Keep talking dirty…. Sorry…. I am grinning from ear to ear!

Bring it …. LFG !!!

Sounds good… let’s see it!

Hopefully all of that heavy precip in SW VA rides right up 81 for us.

Latest CTP Expected Snow map issued an hour ago is similar to earlier versions today

I realize it’s now casting time, but it’s good to see the Hi res Canadian HRDPS & the latest HRRR look decent for most.
