What forecasters said that day

The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS State College, PA wrote its last area forecast discussion before this winter storm warning went out at Feb 19, 12:00 PM EST, 2 hours 34 minutes earlier.

Area forecast discussion, Feb 19, 12:00 PM EST, 2 hours 34 minutes before
Area Forecast Discussion
National Weather Service State College PA
1200 PM EST Tue Feb 19 2019

.SYNOPSIS...
A winter storm will bring significant snow and ice to central
Pennsylvania on Wednesday. Dry and windy weather is forecast
Thursday, with fair weather continuing into Friday. The next
weather system will return precipitation to the area over the
weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
A sprawling area of high pressure (1040 mb) stretched from
northern PA to Wisconsin late this morning, with varying
amounts of thin cirrus streaming NE across the Commonwealth.
High clouds will thicken-up from the southwest early tonight.

Mid afternoon max temperatures will range from the mid 20s
across the north to the mid 30s in the south. The lack of wind
under the dome of high pressure will make it feel a bit warmer
in the sun and compared to Monday with the brisk wind. maxT
departures today will be 5 to 10 degrees.

Clouds will gradually lower and thicken tonight as high
pressure retreats into New England. A strong llvl cold air
damming signature will develop east of the Alleghenies south of
the high center. Hires models and ensembles spread WAA front-
end snow into the Laurel Highlands and south central mtns by
daybreak Wednesday with slippery travel for the AM commute.

The leading/northern edge of the snow shield will be near the RT
22/322 corridor in South-Central PA around 12Z Wednesday.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
*Snow and icy mix will result in travel disruptions Wednesday
 into Wednesday night

The CAD pattern will set the stage for significant snow and ice
event for south-central PA on Wednesday. Strong low-level
theta-e advection of rich GOMEX moisture and favorable mid to
upper level dynamics will support a broad area of wintry precip
overspreading the area Wednesday morning. A burst of heavy snow
appears likely on the front-end with rates 1 in/hr possible
supported by strong upper divergence and low-mid level FGEN.
Hires model data and NBM maxTw aloft indicate that snow will
transition to an icy mix of sleet and freezing rain during the
afternoon/evening before ending (possibly as freezing drizzle)
late Wednesday night.

While we are confident in the overall evolution of the winter
storm with changing ptypes from snow to icy mix, the advancement
of the warm nose will play a key role in the duration (and
therefore amount) of snow vs. ice. This continues to make for a
tricky forecast and is the main reason we decided to ride the
watch for one more cycle. Storm total snow and ice amounts did
increase by an inch or two especially between the PA Turnpike
and I-80. The heaviest snow shifted to the east over the
southern tier Alleghenies adjacent to the MD line centered on
Bedford/Fulton/Franklin Counties.

Any lingering precipitation should end Thursday as increasing
westerly flow directs drier air into the area. High pressure
builds in for Thursday night.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Dry wx continues on Friday before the next Plains-Great Lakes
storm system spreads precipitation back into the area over the
weekend. The storm track/pattern looks somewhat similar to the
midweek event, but with stronger/primary low and weaker sfc
high/CAD. This would favor zr or plain (soaking?) rain but will
wait and see how the ptype details evolve in the coming days.
Temperatures could get quite mild and break into the 50s on
Sunday before turning breezy and cooler by early next week.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
A large area of high pressure will maintain a near certainty of
VFR conditions and light winds over the entire region for this
afternoon through much of tonight.

High clouds thicken up and lower to a widespread altostratus
ceiling based between 8-10 kft agl between 05-10Z Wednesday,
before lowering to widespread LIFR/VLIFR cigs and vsbys in
moderate to occasionally heavy snow between 13-19Z Wednesday.

Conditions will remain IFR or lower late Wednesday through most
or all of Wednesday night as warmer/slightly above freezing air
streams in aloft from the south and changes the snow to MDT to
HVY sleet, then periods of lighter freezing rain late wednesday
afternoon and night.

Outlook...

Wed...Snow (ocnly heavy during the late morning and early
afternoon) changing to to a wintry mix, then mainly freezing
rain before nightfall.

Thu...AM light freezing rain/low cigs possible.

Fri...AM low cigs possible W Mtns.

Sat...PM rain/low cigs possible.

Wednesday night for PAZ027-028-056>059-063>066.
