What forecasters said that day
The local office's own words before this winter weather 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 winter weather advisory went out at Feb 13, 2:24 PM EST, 29 minutes earlier.
Area forecast discussion, Feb 13, 2:24 PM EST, 29 minutes before
Area Forecast Discussion National Weather Service State College PA 224 PM EST Sat Feb 13 2021 .SYNOPSIS... A gradual turn from mainly fast zonal flow aloft to a ridge east and trough west of the area will bring many weather systems through the state over the next week or more. Temperatures are forecast to remain below average into the second half of February. && .NEAR TERM /THROUGH TONIGHT/... Spotty, light mixed precip across the region right now and expect it to continue for pretty much all of the near term. The moisture and uplift and upslope flow will maximize in the first half of the night, making this the most-likely time for any minor accumulations of snow/sleet and any glaze of ice to occur. Nightfall will make the possibility of DZ freezing on roads more possible. Will continue to consider an advy for a light accum of freezing rain, and may issue one shortly if confidence increases only the slightest bit. Would likely not split hairs on where, and just carpet bomb, perhaps startingn the wrn mtns first then expanding to the rest of the area. It would likely only last thru sunrise or shortly after as llvl flow become drier from the W/NW in the morning. Temps go almost nowhere overnight. && .SHORT TERM /SUNDAY/... The wind from the west should dry things out, but little sunshine is expected with a deep inversion and moisture trapped under it. Some sun could peek thru in the west later in the day. Will keep mentions of precip to the early morning, and mainly in the east and upslope of the Laurels. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... An active weather pattern will continue into the long-term, as Pennsylvania remains in the vicinity of baroclinic zone between an anomalous upper-level trough over the Plains states and a ridge off of the East Coast. Latest model guidance suggests that another period of light snow (possibly a light mix across the southeast) is in store for Monday, associated with jet streak over the St Lawrence Valley and associated fgen forcing over PA. The bigger concern comes Monday night into early Tuesday, however, with a wave of low pressure lifting out of the Gulf of Mexico. This moisture-laden system will ride northward along the spine of the Appalachians before transferring energy to the Mid-Atlantic Coast on Tues, and it should bring a swath of significant snow to some portion of central PA, with a wintry mix once again possible across the south. This system will exit the area later Tues, followed by a brief period of fair and seasonable weather for Wednesday as upper level ridging builds into the region. By late week, medium range guidance is indicating another significant area of low pressure will track northward from the Gulf Coast towards PA. Given that this storm is still 7 days away, it's still a little early to pin down the exact track of the low and resulting ptypes. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... Cigs lowering all over under llvl E/SE flow which will become more southerly into the evening. Clouds are heavy with precip, so they may spit something out (snizzle?) at just about any time. P-type very uncertain with no seeding with ice crystals expected over most of the area. All terminals should be decreasing into IFC this evening, with improvement not expected until morning for most. Some may get into LIFR. The very light, patchy mixed precip out there now will become likely for all of the area tonight. Very little if any improvement is expected thru the night as wind goes light and weak upslope flow will continue. Little accums of snow/sleet/ice are expected, though. De-icing will be likely/necessary due to the deep layer of super-cooled clouds which will be encountered on arrival and departure. Despite the gradual veering from E-S-W thru the lowest 6-8kft, the worst shear in wind dir or speed would be aloft and not near the sfc. Some improvement to mainly MVFR cigs and nil precip should occur in the morning on Sunday. Inversion remains in place, though and clouds may only lift slightly. A couple of breaks may occur in the OVC before 18Z, but not likely. Some drying is expected in the aftn, with the wrn terminals with the greatest poss of seeing some sun. Clouds increase again from the SW Sun night, lowering and thickening. Precip (SN) will spread in on Monday as a decent wave aloft lifts in from the TN/OH valleys. Sig accums are possible for all but MDT/LNS. Outlook... Mon-Tue AM...LIFR in snow/mixed precip, esp NW. Tues PM-Wed...IFR mainly NW, then improving to VFR/MVFR briefly. Thu...Restrictions likely. Wintry mix, may change to rain SE. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Dangelo NEAR TERM...Dangelo SHORT TERM...Dangelo LONG TERM...Fitzgerald/Martin/Evanego AVIATION...Dangelo/Colbert

Very light precipitation and fog could be making untreated roads across the Laurel Highlands slippery. The daylight and mild ground temperatures will help to keep many roads just wet. However, bridges are most likely to have ice on them since the air surrounding the entire bridge deck is well below freezing today. Please use extra care today when driving across the region. Assume that any roadway or bridge which appears wet may indeed be icy.
