Someone south of Rt. 30 in Adams, York Lancaster and / or Chester County is going to get rocked in the next 2 hours. Bad a$$ band about to move in. If this was at night..........

You? You're south of 30. Snow is starting to lay on hard surfaces here in Neffsville.

32.5 degrees, 31 dewpoint

New Disco from CTP just out

.SYNOPSIS...

-- Changed Discussion --

A NOREASTER IS DEEPENING RAPIDLY AND WILL CONTINUE TO MOVE ALONG

THE EAST COAST AND SLIGHTLY OFFSHORE. THE HEAVY...WET AND

DESTRUCTIVE EARLY SEASON SNOW WILL CONTINUE THROUGH THE LATE

AFTERNOON IN THE WEST AND EVENING IN THE EAST. MUCH OF THE REGION

WILL SEE BETWEEN 4 AND 8 INCHES OF SNOW BY THE EVENING...WITH HIGH

ELEVATIONS RECEIVING EVEN HIGHER AMOUNTS. SLIGHTLY LOWER AMOUNTS

WILL FALL ACROSS THE NORTHWEST MOUNTAINS.

HIGH PRESSURE WILL BUILD NORTHEAST FROM THE TENNESSEE VALLEY FOR

SATURDAY NIGHT AND SUNDAY...WITH CLEARING SKIES. MODERATING

TEMPERATURES ARE EXPECTED EARLY NEXT WEEK.

-- End Changed Discussion --

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

-- Changed Discussion --

BARELY ANY TWEAKS NEEDED FOR THIS UPDATE. ALL AIR TEMPS NOW 33F OR

LESS EXCEPT IN IPT AND SEG AND VSBYS LESS THAN A MILE. SEG IN A

GOOD BAND NOW AND HAS GONE TO PLAIN SNOW DESPITE 36F TEMP. ALL IS

GOING AS PLANNED WITH CLOUD TOPS COOLING VERY WELL OVER THE

AREA...WITH THE TOPS NOW -45 TO -50C. TRAVEL OVER THE LARUELS

ALREADY VERY DANGEROUS WITH ROADS SNOW COVERED AND HEAVY SNOW

FALLING. SNOWFALL RATES WILL BE AN INCH PER HOUR IN THE HEAVY

BANDS. ACCUMS IN THE 18Z TO 00Z TIME FRAME SHOULD AVERAGE 2 TO 4

INCHES EXCEPT HIGHER-ELEVATION LOCATIONS TO THE EAST OF STATE

COLLEGE AND ALTOONA. FAR SE LANCASTER COUNTY MAY SEE MORE RAIN

THAN SNOW AND SOMEWHAT LESSER ACCUMULATIONS. WINDS ARE BACKING AND

ONLY PULLING IN DRIER AIR TO HELP FURTHER COOL THINGS OFF AS

EVAPO/DYNAMIC COOLING WORK AS WELL.

UNDOUBTEDLY...THE MOST SIGNIFICANT IMPACT FROM THIS STORM WILL

COME IN THE FORM OF WIDESPREAD DOWNED TREES AND POWER OUTAGES FROM

THE HEAVY WEIGHT OF THE SNOW ON THE STILL FOLIAGE LADEN TREES. ITS

POSSIBLE THAT POWER LOSSES COULD LAST FOR UP TO SEVERAL DAYS FROM

EXTENSIVE DOWNED TREES/UTILITY LINES.

So I have to ask this... until I moved here/checked out these threads, I had only rarely heard the word "lay" when referring to sticking snow. Is that a Pennsylvania thing? Or an east coast thing? Does anyone know?

I've always just called it "sticking" FWIW.

I think it's an eastern regional thing. I bet it sounds funny to you, lol.

BTW, aren't these heavier bands showing up a bit early? I didn't expect them until early afternoon and I think a few mets are thinking the same thing.

Maybe, but not by a lot I think. Maybe an hour early? Early could mean one of two things--more heavy bands and more snow, or just an earlier progression of the system and the same amount of snow.

To me, this has been right on schedule. We were talking at the office last night at how the snow might wrap up pretty quick during the Penn State game today.

In the south it's "stick". And instead of a coating it's "dusting". Interesting CTP says 2-4" after 2pm...with sun angle decreasing from 1:30 onward and upper levels cooling that could be when it piles up if it plays out how they think it will.
