What forecasters said that day
The local office's own words before this winter storm watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pittsburgh, PA wrote its last area forecast discussion before this winter storm watch went out at Feb 13, 8:19 AM EST, 5 hours 36 minutes earlier.
Area forecast discussion, Feb 13, 8:19 AM EST, 5 hours 36 minutes before
Area Forecast Discussion National Weather Service Pittsburgh PA 819 AM EST Sat Feb 13 2021 .SYNOPSIS... Periodic precipitation chance and seasonably cold temperature will continue through next week. && .NEAR TERM /THROUGH SUNDAY/... 815am update...a combination of ground reports and weak radar returns suggest accumulating freezing rain/drizzle has developed over eastern Tucker County. Given potential for this precipitation type to linger through the day, have issued a Winter Weather Advisory. Generally a glaze of ice accumulation is expected due to meager moisture and low QPF model output. There remains a potential need to further expand the advisory north and east if freezing rain/drizzle becomes the predominant precipitation type moving forward as the shortwave crosses the region. Previous Discussion... Upper flow is backing to the southwest in response to a digging trough over the central CONUS. Light precipitation chance returns today with the approach and passage of a weak shortwave within this flow. Changing frontal orientation and warm advection indicate mixed precip for the area with model soundings showing sparse mid level moisture with the warmth capping a saturating boundary layer. As the ascent signal and mid-moisture are very limited, only chance pops were maintained for some light snow with efficiency compromised by the aforementioned mid level warmth. Light freezing rain or drizzle is also possible though given the moist sfc layer, but confidence in problematic ice accumulation is low at moment, so no advisory will be issued for now. Shortwave ridging is expected to keep Sunday mostly dry in the wake of todays disturbance. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... The sw flow over the Upper OH is forecast to continue through mid week with a series of crossing shortwaves within flow defining precip chances. The first of significance is indicated for late Sunday night and early Monday, while another and stronger impulse is timed for Monday night with an early Tuesday exit. Models are not consistent in depictions of omega/ascent magnitude with the first of these systems on Monday with GFS being much stronger, although deterministic trends of timing and more of an open wave situation are in line. The second on Monday night is stronger in the ascent field given indications of at least a brief coupled jet/enhanced frontogenesis scenario; however, all models rapidly encroach a mid level dry slot early on Tuesday which will shut down problematic precipitation efficiency. In addition, the shifting baroclinic zone in the southwest flow pattern will degrade snowfall efficiency for part of the area, but add the element of mixed precip including freezing rain to the problem. At moment, the mid level frontogenetic zone is indicated just northwest of Pittsburgh and that is where the heavier snow forecast was drawn for these two shortwave passages. With a break indicated Monday afternoon, the question of a collaborated headline at this point is not clear. Nonetheless, hazardous wintry weather should be anticipated, especially on Monday night, and headlines are likely. && .LONG TERM /WEDNESDAY THROUGH FRIDAY/... The southwest flow pattern is forecast to continue with yet another potent embedded shortwave indicated for late week. && .AVIATION /13Z SATURDAY THROUGH WEDNESDAY/... VFR prevails early this morning, but MVFR cigs will shift northward through the morning hours in advance of the next shortwave. Thus have put some TEMPO groups in for most of the terminals to highlight that transition period. The shortwave will bring light precipitation to the region in the form of snow and/or freezing rain mainly after 14z. Further deterioration to IFR is expected by this afternoon, with restrictions continuing through tonight. .Outlook... Widespread restrictions are expected again Monday and Tuesday with another winter system. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...Winter Weather Advisory until 7 PM EST this evening for WVZ514. &&
