What forecasters said that day
The local office's own words before this wind advisory 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 advisory went out at Jan 12, 2:07 AM EST, 2 hours 7 minutes earlier.
Area forecast discussion, Jan 12, 2:07 AM EST, 2 hours 7 minutes before
Area Forecast Discussion National Weather Service State College PA 207 AM EST Fri Jan 12 2024 .SYNOPSIS... A few snow flurries are lingering across the northern tier of the state this evening as a weak disturbance moves NE of PA. Another multi-hazard winter storm will impact the area Friday into Saturday with wind, rain, and snow. Lake effect snow and blustery conditions over the weekend will mark the start of a colder pattern into mid January with below normal temperatures and frigid wind chills expected next week. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... A few light snow showers are continuing across north western portions of PA this evening as the short wave that moved across southern Ontario continues to push towards the north and east. These snow showers should dissipate by midnight. The remaining overnight hours will be dry, with lingering clouds over northern PA and clear-partly cloudy skies from about I-78/US-22 on south. Winds will shift to become more easterly ahead of the storm system expected to reach the region by Friday afternoon. Lows by daybreak will range in the 20s to low 30s. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/... Overall latest guidance has reinforced confidence on the strength and timing of the system expected to reach the central PA area on Friday afternoon. An area of note that was not previously mentioned is the possibility of gusty SE winds late Friday night into early Saturday associated with the frontal passage in the Susquehanna Valley and along our eastern CWA. Guidance currently suggest 40-45 knot gusts are possible ahead of the colder air. Previous Discussion... As previously mentioned another multi-hazard event is on-deck from Friday afternoon into Saturday, as a deep surface low, supported by a negatively tilted upper-level trough, lifts through the upper Midwest into western Ontario. A strong S-SE low-level jet will be in place tomorrow and fuel both gusty winds and a leading shot of warm advection precipitation. From about I-80 northward, precipitation type will initially take the form of snow, and some heavier snow bands are expected given strong forcing. The combination of 2-5" accumulations and very gusty winds justifies a Winter Weather Advisory for the northern tier Friday afternoon and evening. As earlier mentioned, strong winds will also be a concern, with the Alleghenies and Laurels most under the gun for 40-50+ knot gusts. We've opted for a High Wind Warning for the Laurel Highlands and a Wind Advisory for the northern Alleghenies and northwestern PA. We feel lower QPF trends in recent model runs and rapid system motion should limit rainfall enough to prevent future flooding problems. Thus, we did not issue a Flood Watch. Rain will be steadiest during the evening hours, but should cut off by or shortly after midnight. On Saturday, colder air will move in, leading to slowly falling temperatures over time, and accompanied upslope and lake enhanced snow showers. Winds will ramp up again Saturday from the west. We'll give this a closer look with future model runs, before making a final decision on possible wind headlines Saturday. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... Late evening update holds mainly changes to make sure to cap PoPs at 50pct in the Tuesday-ish time frame. Lots of spread among GFS and ECMWF - and inside the GEFS members - as to the track of a potential ECSS for mid-week. The most certain part of this forecast is that the cold air in place from the invasion on Sunday should keep it cold no matter what happens with a sfc low which may or may not roll up the coast. We haven't see a day with the high temp in the teens for almost a year in State College, PA. That looks like it could happen mid-week with highs only in the 20s for most of the week. It would be more certain if we were to have a good snowpack on the ground. Prev... *Coldest air so far this winter poised to invade Sunday and persist through the middle of next week.* Lingering lake-effect snow showers across northern and western PA will gradually dissipate on Sunday, as a weak area of high pressure builds in. Sunday will be a chilly day, however, with high temperatures running 5 to 15 degrees below average for mid January. Long-range models continue to produce a synoptic snowfall across central PA next week, but the timing has trended a bit later. Low pressure is progged to develop off the southeast coast of the United States and track north- northeastward. The current timing is Tuesday into Wednesday. The extended range models are in good agreement that it will remain cold through the middle of next week, with a reinforcing shot of cold air arriving on Tuesday night behind the departing low. Temperature departures will be in the -5 to -15F range compared to normal corresponding to low temperatures in the single digits to teens and high temperatures in the teens to low 30s. && .AVIATION /07Z FRIDAY THROUGH TUESDAY/... A deck of stratus persists across the northern tier of PA this evening, with a broken deck developing immediately to the south across the Laurels and Ridge and Valley regions. Cigs are mostly MVFR within these cloud decks, but IFR cigs are possible at BFD. Elsewhere, conds will remain VFR. Winds will be from 270 to 310 during the first part of the night, with gusts of 15 to 20 kts. This wind direction should keep lake effect snow showers north of BFD overnight. Winds will taper off during the predawn hours and shift to 100-130 by Friday morning. Conditions will improve areawide Friday morning with strengthening southeasterly winds gusting 30 to 50 kts during the afternoon and evening - highest in the Laurels and the Lower Susq. There is a large degree of uncertainty in the wind gust potential due to uncertainty in the strength of the low level temperature inversion. LLWS will also be a concern. Snow, sleet, and rain arrives from southwest to northeast Friday evening with widespread MVFR/IFR restrictions overnight. Outlook... Sat-Sun...Windy with snow showers N/W and improving conds across the SE. Mon...Snow developing from south to north late. Mon night-Tues...Periods of snow. && .HYDROLOGY... Several mainstem Susquehanna River points have crested or are forecast to crest near or above action stage. These points will likely remain elevated into the weekend given the next round of heavy rainfall forecast to bring renewed but less certain flooding concerns Friday night into Saturday for the lower Susquehanna tribs. && .CTP WATCHES/WARNINGS/ADVISORIES... Wind Advisory from noon today to midnight EST tonight for PAZ004>006-010-011-017. Winter Weather Advisory from 4 PM this afternoon to 1 AM EST Saturday for PAZ005-006-037.
