ApffelWhat 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 Buffalo, NY wrote its last area forecast discussion before this winter storm watch went out at Dec 4, 12:39 AM EST, 2 hours 59 minutes earlier.
Area forecast discussion, Dec 4, 12:39 AM EST, 2 hours 59 minutes before
Area Forecast Discussion National Weather Service Buffalo NY 1239 AM EST Mon Dec 4 2017 .SYNOPSIS... High pressure over New England will bring tranquil and mild weather through Monday. A cold front will then cross the region Tuesday with periods of rain. This front will usher in a much colder airmass for Wednesday through the end of next week, which will set the stage for significant lake effect snows east and northeast of Lakes Erie and Ontario Wednesday through Thursday night. && .NEAR TERM /THROUGH TODAY/... Regional show relatively thin fog becoming common across the area early this morning, especially on the lake plains. The fog will continue to expand overnight, but increasing mid/high clouds should keep it from becoming too dense. High pressure across New England will continue to influence our weather tonight, which will keep the area precipitation-free. The main forecast concern continues to be the development of fog and stratus which did develop across Southern Ontario and northern Michigan last night. NAM/HRRR guidance continue to show fog developing again tonight, mainly across the lake plains from Buffalo to Rochester. Although the GFS does not show this, it did not capture the fog last night as well, so based on this have added areas of fog to the forecast. The one lingering concern is increasing high cloud cover and a modest southerly flow late tonight. This may cause fog which does develop to lift northward over Lake Ontario and begin to dissipate before sunrise. Otherwise, expect lows in the lower 30s on the lake plains and mid to upper 20s for the interior Southern Tier valleys and east of Lake Ontario. Monday's weather still looks quite nice with an increasing southerly flow as high pressure slides to the New England coast. Temperatures should climb well into the 50s across the lake plains, and it may be some time before these areas top 50 degrees again. Winds will increase throughout the day, becoming rather gusty during the afternoon hours. && .SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/... Monday night, western and central NY will become situated within increasingly strong southwesterly flow and warm/moist advection ahead of an approaching cold front and 50+kt low level jet. The front will be associated with a rapidly deepening surface low lifting from the Minnesota arrowhead into central Ontario Province. Latest expectations are for the first half of Monday night to be mainly dry. An anomalously high plume of subtropical moisture, with Pwats 2-3 SD above normal, will then begin to bring a widespread soaking rainfall in western NY early Tuesday morning. This will spread east into central NY through Tuesday with basin average QPF based on 03/12z guidance 0.25-0.5 inches for most of our area but now a little higher than previous guidance for the western Southern Tier and eastern Lake Ontario Region. In these two locations QPF is about 0.5-0.75 with an isolated inch possible as well on the Tug. Temperatures will remain very mild Monday night and Tuesday ahead of the front, with lows only slipping into the 40s Monday night then highs reaching into the mid 50s Tuesday despite the thick cloud cover and rainfall. Additionally a stiff south veering to southwesterly flow will bring winds gusting 25-35 mph ahead of the front. Cold air advection and rising surface pressures will help to taper off rain from west to east Tuesday evening while bringing a threat for perhaps some advisory level wind gusts down wind of Lakes Erie and Ontario. This is possible as a lingering 45-50kt jet is mixed down in cold advection along with some funneling along the lakes. Gusts of 35-45 mph have been included for now based on 12z GFS but could end up being stronger and will need to be watched. Temperatures will fall sharply through the 40s and into the 30s as 850mb temps cool toward -10C with a shortwave trough pivoting across the eastern Great Lakes. The quickly falling temps may cause the synoptic precip to change over to snow over the higher terrain before ending. Lake effect snow looks to develop quickly in southwest flow on the heels of the departing synoptic precipitation early Wednesday morning as lake induced equilibrium levels rise sharply to around 10kft. The snow bands should be focused mainly south of metro Buffalo and Watertown but will be relatively tame the first half of the day as synoptic moisture does not ramp up until later Wednesday. Do to this, we still expect a less favorable period for lake effect through mid-day Wednesday with the more limited moisture and elevated shear behind a departing shortwave. Wednesday afternoon into Wednesday night lake effect snows are expected to ramp up in intensity as equilibrium levels rise above 10kft with plentiful moisture and lift reaching into the favorable dendritic snow growth zone per BUFKIT point soundings. The flow through Wednesday night looks to remain about 250 deg which should favor band placement to remain just south of Metro Buffalo and Watertown although the exact placement of these bands could shift with several days to go before the event unfolds. The event could be the first significant lake effect snow event this season as CIPS Analogs using 12z GFS valid Thursday afternoon indicate 72h Median COOP Snowfall greater than 8 inches off Lake Erie and greater than 12 inches off Lake Ontario. Outside of these snow bands, there is just a chance of some light snow showers in cyclonic flow aloft. Winds will remain rather blustery through Wednesday which will combine with Temps in the 30s to bring wind chill temps in the 20s Wednesday. Winds and temps in the 20s Wednesday night will bring wind chills dipping into the teens. && .LONG TERM /THURSDAY THROUGH SUNDAY/... ...Potentially significant lake effect snow event to continue through Thursday... Lake effect snow parameters continue to look impressive, therefore maintaining the potential for significant lake effect snows lasting through the day Thursday. The combination of increasing over-lake instability with lake induced cape of 500+ J/kg, sufficient moisture through the entire column with no threat for dry air entrainment above the forecast 10-12kft inversion, well aligned flow in the lake induced convective boundary layer for well organized banding structures, and subtle synoptic support from a mid level shortwave pinwheeling through the deepening trough overhead, all yield increasing confidence in the potential of a prolonged period of heavy snow. Combined with blowing snow, hazardous travel conditions will likely develop during this time. Latest models still suggesting the more dominant steering winds will be a west to southwest flow direction, with a brief period of westerly flow developing Thursday night. Although it still remains too soon to pinpoint amounts or the areas of highest impact, those residing in the typical snowbelts east of Lakes Erie and Ontario, including Buffalo and Watertown, will want to pay particularly close attention to the forecast over the next few days as the details become more clear. The approach of a shortwave Friday will likely disrupt the ongoing lake effect snow within increasing shear profiles. However, before the lake effect plumes full dissipate, they may move quickly across the Niagara Frontier and Saint Lawrence valley by Thursday evening. Whether or not the lake snows completely fall apart is more uncertain, but there will certainly be enough cold air in place to at least keep some general snow or weaker lake effect snow going through Friday. Once this shortwave clears, another surge of arctic air looks to arrive across the lower Great Lakes. It continues to look reasonable that another round of significant lake effect snow will ramp up over the upcoming weekend. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... Areas of fog will continue to develop overnight with areas of IFR most common on the lake plains and also in the Southern Tier valleys. The fog will dissipate early Monday morning as southerly winds increase mixing. Mid level clouds will overspread the area on Monday ahead of the next system, with VFR prevailing once the fog dissipates. Mid level clouds will continue to thicken and lower Monday night, and southerly winds will continue to increase and become more gusty. Outlook... Monday night...VFR. LLWS likely. Tuesday...MVFR/IFR with periods of rain. Wednesday and Thursday...Lake effect snow with local IFR east and northeast of the lakes. Mainly VFR outside lake effect areas. Friday...VFR/MVFR. Snow showers likely. && .MARINE... High pressure over New England tonight will slide to the New England coast on Monday. Southerly winds will increase later Monday and Monday night ahead of a strong cold front, likely bringing the next round of Small Craft Advisory conditions. These winds will become southwest later Tuesday and Tuesday night behind the cold front, with Small Craft Advisory conditions likely continuing through at least Thursday. && .BUF WATCHES/WARNINGS/ADVISORIES...
