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 Mar 6, 9:42 AM EST, 2 hours 17 minutes earlier.
Area forecast discussion, Mar 6, 9:42 AM EST, 2 hours 17 minutes before
Area Forecast Discussion National Weather Service State College PA 942 AM EST Tue Mar 6 2018 .SYNOPSIS... A winter storm system will bring accumulating snow to much of central Pennsylvania Tuesday night into Wednesday. The heaviest snowfall and area of greatest impact is expected to be focused over east-central Pennsylvania. Periods of snow are likely to continue over the northwest Alleghenies and Laurel Highlands with additional snow accumulation through the end of the week. Temperatures will stay below average into the weekend. && .NEAR TERM /THROUGH TONIGHT/... Increasing clouds today with spotty/light precip increasing in coverage later this afternoon into early tonight. Expect rain/snow mix in the valleys and wet snow at higher elevations, eventually trending toward greater coverage of wet snow overnight with nightfall helping to produce a slushy coating to an inch or so by Wednesday morning. && .SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/... Computer models show rapid coastal surface low development over the eastern Carolinas late Tue. night moving up the northern Mid Atlantic coast (just east of the Delmarva/NJ coast) Wednesday. The potent winter storm will develop into a Nor'easter with the potential to bring heavy snow to parts of east-central PA during the daylight hours Wednesday. Tight gradients in the QPF lead to continued uncertainty on the western edge of the precip shield. Due to tight gradient and the forecast snow accumulation window falling just outside of the 06/00Z HREF solution envelope, opted to ride the watch for one more cycle and allow the dayshift to issue advisory and/or warning headlines. The track of the surface low will be of great importance regarding snow impacts and tight gradients in the snowfall amounts. Slight west/east shifts in the track could make a big difference across east-central PA. Highest confidence and multi-model ensemble probabilities for significant snow is along/east of the I-81 and US-15 corridor. A period of intense snowfall rates is possible Wednesday with 1-2 in/hr rates in the deformation zone snow bands. Snow intensity should be trending down by Wednesday night as gusty, downslope/westerly flow eventually takes control of the large scale synoptic pattern. && .LONG TERM /THURSDAY THROUGH MONDAY/... Upper low rotates through the area Thu-Fri combining with seasonably cold westerly flow to prolong snow showers downwind of the lakes and over the favored upslope areas along the Allegheny Plateau. This will support additional snow accumulation through the end of the week across the higher elevations in the Laurel Highlands and northwest Alleghenies. Storm potential still very much up in the air heading into early next week with very low confidence given a large spread in the guidance. Greater confidence exists in a continuation of below average/seasonably cool temperatures for early to mid March. && .AVIATION /15Z TUESDAY THROUGH SATURDAY/... To start, an area of MVFR stratocu continues to shrink over parts of the northern mountains, and will recede into NY state around 13z. The first half of the day today will bring widespread VFR conditions as light winds swing around to the SE and increase to around 10 mph. Then focus turns to an approaching winter storm system that will bring widespread restrictions (and winter weather) to the region. A weakening occluded front will push in from the west this afternoon, with ceiling restrictions developing from west to east through the afternoon and mid evening. Timed the restrictions to begin at JST/BFD around 18z, 21-23z at AOO/UNV, and 00Z at IPT/MDT/LNS. Light rain and snow showers will accompany the front. Main player then becomes a rapidly developing coastal low that will reinforce low ceilings and bring accumulating snow to much of central Pennsylvania tonight into Wednesday. The heaviest snowfall and area of greatest impact is expected to be focused over eastern Pennsylvania east of the Susquehanna River. Restrictions and periods of snow are likely to continue over the northwest Alleghenies and Laurel Highlands with additional snow accumulation through the end of the week. Outlook...
