What forecasters said that day
The local office's own words before this wind chill 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 wind chill warning went out at Jan 20, 2:55 AM EST, 1 hour 11 minutes earlier.
Area forecast discussion, Jan 20, 2:55 AM EST, 1 hour 11 minutes before
Area Forecast Discussion National Weather Service State College PA 255 AM EST Sun Jan 20 2019 .SYNOPSIS... A polar plunge of arctic air will follow the winter storm with sharply falling temperatures today potentially leading to rapid freeze-ups and additional travel disruptions. Frigid temperatures and blustery winds will produce bitter cold to dangerous wind chills tonight into Monday. Temperatures will trend milder on Tuesday with the next storm system likely bringing mixed precipitation on Wednesday. && .NEAR TERM /THROUGH TONIGHT/... *Winter storm impacts shifting from snow/icy mix to bitter cold *Dangerous wind chills tonight into early Monday morning Mixed precip transition zone has shifted north of I-80 allowing for changeover from snow to sleet/freezing rain/rain at KDUJ/KFIG/KUNV/KIPT. Expect stripe of icy mix or rain along the I-99/US-220 corridor through 12Z with plain rain southeast of I-81. We will likely drop the winter wx advisory for the lower Susquehanna Valley with the next update. Radar trends show precip filling in the dry slot lifting northeast across nrn WV into SW PA. Band of moderate snow should expand over the northern tier. Hires models show the back edge of precip shield transitioning back to snow as it pivots into central PA through late morning. The heaviest snow (additional 2-4") through 12Z will be confined to the northern tier counties/US-6 corridor. An additional coating to 1 inch is possible in the 12-18Z timeframe across the northwest 1/2 of the CWA especially in the Laurel Highlands and Endless Mtns. As snow and mixed precip comes to an end in most places by midday, focus will shift to impacts associated with an arctic blast of brutally cold air this afternoon through tonight. Gusty northwest winds will direct much colder air into the region as the storm pulls away. High temps today will occur in the morning with temperatures expected to fall through the afternoon, reaching the single digits and teens by evening. Gusty winds combined with the frigid temperatures will result in bitter cold to dangerous wind chills in the 10 to 25F below zero range. Windy conditions may also contribute to blowing and drifting snow over the norther tier. Plan to issue wind chill advisories/warnings with the next update. The plummeting temperatures could result in a rapid freeze up of slush/standing water on roads and lead to additional travel problems. The brutal cold will hinder storm clean-up/snow removal and recovery efforts. Despite the surge of arctic air charging across the Grt Lks, low PWAT air and low inversion heights will result in little lake effect snow across the snowbelt and favored upslope areas. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Very cold temperatures to start next week with highs in the single digits to low teens with subzero wind chills. Temperatures will trend milder through midweek. Scattered snow showers and flurries will linger on Monday. Clearing skies and fresh snow cover under strong arctic high pressure may produce the coldest minimum temps Tuesday morning. Fair wx expected Tuesday with some recovery in temperatures. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Another shot of wintry weather appears likely toward midweek. The pattern looks to remain fairly active with the potential for more storms followed by cold shots through next weekend. && .AVIATION /07Z SUNDAY THROUGH THURSDAY/... Steady precipitation shield starting to show some erosion in the west, but still overall a fairly large area of precipitation remains across central Pennsylvania. Mainly snow continues north of I-80 corridor at 06z, but PL/FZRA widespread south of this, with just plain rain across the far south and southeast. Mixed precipitation making a strong push northward, and expecting KIPT and KUNV to likely transition to all PL, if not FZRA. Precipitation will transition back to snow on the very backside of the system as it exits to the east during the morning. Behind the system, snow showers will linger across the northern and western mountains during the day. Strong winds will cause some blowing snow across the north, where no ice fell, and will likely affect KBFD. Overall, conditions improving to MVFR across the mountains, with eventual VFR elsewhere. Outlook... Sun Nite/Mon...MVFR cigs and snow showers NW 1/2. VFR elsewhere. Tue...Mainly VFR. Wed...Restrictions likely with rain or showers. Thu...MVFR/VFR with scattered snow showers. && .CTP WATCHES/WARNINGS/ADVISORIES...
