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 12, 3:01 PM EDT, 23 minutes earlier.
Area forecast discussion, Mar 12, 3:01 PM EDT, 23 minutes before
Area Forecast Discussion National Weather Service State College PA 301 PM EDT Sun Mar 12 2017 .SYNOPSIS... Unusually cold air will remain in place through Monday. A major winter storm is expected to bring a moderate to major snowfall for much of Central Pennsylvania Monday night through Tuesday night. After a period of lake effect snow during mid-week and brief high pressure at the end of the week, a very active and unsettled pattern will begin. && .NEAR TERM /UNTIL 11 PM THIS EVENING/... Adjusted grids some for flurries across the north, and cloud cover. Prev... High pressure will provide another mostly dry and cold day today across the Commonwealth. Diminishing, cold northwest flow across the unfrozen lakes of Huron, Michigan and Erie will still keep a few flurries going over the Northwest Mountains with little if any additional accumulation there. High temps will be just a few degrees higher than Saturday. Late morning and afternoon stratocu development from the lakes will clear out by Sunday evening over all but the northwest Highs will range from near 20F north to the lower to middle 30s southeast. && .SHORT TERM /11 PM THIS EVENING THROUGH 6 PM MONDAY/... Did lower low temperatures and dewpoints tonight, as skies clear. Some high and mid clouds late, but did slow things down. For Monday, not a lot of change, mainly a degree here and there. Earlier discussion below. With clearing skies temps will again drop into the single digits and teens...as 1034 MB sfc ridge axis traverses the region. The high passes off the coast early Monday as coastal front and secondary low pressure start to organize along the Mid atlantic coast. No significant changes overnight to overall thinking. High pressure to north gives a quiet day on Monday ahead of a significant late- winter storm (Miller-B type) system. Track will determine where the highest totals will fall. Expect an area of 6+ inches over the CWA with higher amounts possible mostly likely over eastern portion of CWA. GEFS shows a fairly robust snow across the CWA...and the latest ECMWF has increased QPF back to previous totals across the central mountains with 0.8" water equivalent forecast from 00z Sun run...after having previously backed off with a farther offshore track. Bottom line...we are still 36 hours before the first flakes fall, and the parent upper trof is now crossing the northern Rockies...so fine tuning will be in order through Monday. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... *Late-winter heavy snow risk Monday night-Tuesday Collaboration with PBZ and CLE resulted in westward expansion of previously issued Winter Storm Watches, which now cover all of my counties. some portions of the West Central and Northwest Mountains may struggle to reach 8 inches in 24 hours, or 6 inches in 12, but a high end Advisory at the least appears quite likely. With confidence approaching 50 percent for heavy snow criteria to be met, expanded Watches in collaboration with PBZ and CLE. The heaviest snowfall should occur between 08z Tue and 15z Tue...when 1-2" per hour rates are expected for several hours from the pre dawn to 900 AM Tuesday. Overall amounts expected: 6-8" west...7-9" central and 8-12" east and southeast. As always with Miller-B systems, dry slot from parent sfc low will need to be watched as accumulating snow could shut off quickly from the southwest with an earlier intrusion early Tuesday. Deformation will keep at least light snow going across central PA into Tuesday afternoon with the potential for a few to several more inches where that deformation establishes itself...most likely along the Highway 11/15 corridor and points east. A reinforcing surge of cold air will follow behind the storm with snow showers Wed-Thu. Temperatures well below average Wed behind the system with a slow moderation through the extended but still below average. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... Mid deck was here earlier, but heating of the deep cold air has resulted in more low clouds, wind, and even some flurries. 18Z TAFS sent. For 18Z TAFS, slowed down high and mid level clds from the storm moving eastward from the plains. Monday looks VFR until very late in the afternoon in the NW, and after sunset in the SE. A widespread winter storm will then begin. Heavy snow and LIFR cigs and visbys in +SN are expected Mon night and Tuesday. Outlook... Mon Night-Tue AM...Widespread LIFR in +SN. Tues PM...SN ending S-N in the east, but continuing in the W. Generally improving to IFR W and MVFR E. Wed...Mainly VFR, with residual MVFR conditions in snow showers, especially in the west and north. Windy. Thu...Mainly VFR, with residual MVFR conditions in snow showers in the west and north. Winds slowly diminishing. Fri...Mainly VFR. && .CTP WATCHES/WARNINGS/ADVISORIES...
