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 Juneau, AK wrote its last area forecast discussion before this winter storm warning went out at Jan 30, 2:53 PM AKST, 14 hours 51 minutes earlier.
Area forecast discussion, Jan 30, 2:53 PM AKST, 14 hours 51 minutes before
Southeast Alaska Forecast Discussion National Weather Service Juneau AK 253 PM AKST Sat Jan 30 2021 .SHORT TERM.../Through Monday/ Multiple low pressure centers continue to swirl around the Gulf of Alaska and panhandle today. Satellite imagery shows at least 3 separate circulation centers in the gulf with a fourth stronger one south of Haida Gwaii. These lows have been sending waves of showers (mostly snow) over the panhandle for the last 24 hours or so. Received snow reports have been low with up to 3 inches received in some places overnight. Not much has changed Through Sun night as the showers are still expected to diminish through the next 12 hours. This is mainly due to northerly outflow increasing tonight ahead of a new push of cold air from the north. Winds in Lynn Canal are expected to reach 25 to 30 kt winds coming out of Taku Inlet and Cross Sound at the same time. More significant changes start showing up for Mon as a new low forms in the northern gulf while outflow starts getting stronger. Some more detail was added to the outflow winds compared to previous forecasts, but overall wind changes were not that substantial (Gale force winds still expected for Lynn Canal Mon) Temperatures will also be cooling off again with some areas in the northern half barely reaching 30 for highs on Mon. The largest change in the forecast occurred at the end of the short range Mon into Mon night as a low develops in the northern gulf and slides SE. Current guidance has it sliding SE noticeably faster then the previous forecast depicted, with the Nam and Canadian faster then the ECMWF and GFS. However, Ensemble means were supporting the slower solutions of the GFS and ECMWF, so headed in that direction, but those were still a good 3 to 6 hours faster then the previous forecast. Something to keep an eye on as well, is that guidance is trying to form a convergence zone over Kupreanof and Kuiu Island areas Mon into Mon night that could result in some significant snow falls for those areas. Kept them around advisory criteria for now, as confidence is low where exactly it will set up, if it sets up at all, but snow totals could range much higher or lower then currently depicted. .LONG TERM.../Monday through Saturday night/ Extended forecast period begins with a low pressure system encroaching on the region from the west. A strong pressure gradient across the northern panhandle will be the catalyst for some decent winds from Yakutat to Skagway and areas south to the Icy Strait corridor and Stephens Passage. Most areas should already be sufficiently cold from offshore flow to see some snow from this system. While this is not looking to be a particularly wet system, models are beginning to come into agreement that there may be a bit more moisture with this initial event than previously thought. While highest snowfall totals still look to be set for northern areas, there is growing indication that areas as far south as Ketchikan could see an inch or two. For the time being, have switched gears from the previous forecast and opted to leave the higher precip amounts in for further scrutiny as the event draws nearer, however, should offshore flow win out, this precip heavy forecast may not come to fruition. The next system that will impact the region moves in Tuesday night into Wednesday. Still a decent amount of uncertainty exists with this particular feature. While again, ambient conditions should be cold enough across the region to initially support snow, flow around this system will be coming in from the south. The northern extent of this push of relatively warmer air will again open up the forecast challenge of determining where the elusive rain/snow line will be established. Combined with the notion that any existing snow on the ground could contribute to evaporative cooling makes this event too difficult to speculate on particular impacts with any certainty at this time. What is known is that this does look to have a tropical connection unlike it's predecessor which could bring a decent amount of precip to the region. After this system passes, another brief break in the active weather pattern looks on tap before yet another system potentially makes its way toward the region late week. && .AJK WATCHES/WARNINGS/ADVISORIES...
