Area forecast discussion, Sep 30, 1:38 PM AKDT, 15 hours 9 minutes before
Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 138 PM AKDT Thu Sep 30 2021 .SYNOPSIS... Winter is starting early for the Interior as another winter storm is primed to move across the Alaska Range and north into the Eastern and Central Interior, beginning Friday and continuing through the weekend. Significant snowfall will likely fall from the Alaska Range north through the Interior, and across the Brooks Range to the eastern North Slope. Out west, strong north winds and snow showers will impact the coastal areas. && .DISCUSSION... Upper Levels and Analysis... There is a powerful low center over the western Bering Sea diving south toward the Aleutian Chain. A triple point low is forming along the eastern edge of the larger trough, and this is moving into the Gulf of Alaska this morning. A weak shortwave trough is crossing the AK Range with light snow across the Eastern AK Range and into the Fortymile highlands. The arctic trough is firmly planted over the Mainland, with an onshore gradient favoring light snow showers currently over the North Slope. Model Discussion... The numerical models are in very good agreement with the large scale pattern, but in less agreement with the smaller scale details as two waves of energy lift northwest into the Interior from the Gulf of Alaska. The issue of concern is the discrepancy of the leading triple point low moving into the Eastern Interior tomorrow, and just how far west it retrogrades. This in turn impacts the next low and how far west it moves on Saturday and Sunday. The NAM and ECMWf and Canadian models are all in good agreement bringing a band of snow to the Eastern Interior including the Tanana Valley and Alaska Range, while the GFS splits the trough in two, sending energy much farther east, which brings in 1/4 the amount of snowfall through the weekend. This forecast is tossing that solution out, thus going with much more snowfall for the Interior through 72 hours. Central and Eastern Interior... Snow is expected to return, the first round coming tomorrow midday and into the evening a leading front from the Bering Sea shifts inland. Snow will cross the Eastern AK Range tonight, then move into the Tanana Valley, Yukon Flats, and Minto Flats by the afternoon. There remains some discrepancy with this front and just how fast it rotates through, but the general thinking is there will be a good burst of snow as it moves through, which would be around midday into the evening for much of the lower and middle Tanana Valley. Expect 1-3" with this system. Attention turns to another low moving into the Interior, this time from the Yukon, which will bring a round two of snow, but over a much broader area and for a longer duration, beginning Friday night and persisting into Sunday. Expecting heavy snow for the Eastern Ak Range and Fortymile, with moderate snowfall into the Tanana Valley and west, with upwards of 8-10" possible across parts of the Taylor, AK Highway, and Richardson Highway. This storm through Sunday looks to bring a more widespread snowfall than the previous, with locally heavier snowfall than the last early season storm. West Coast and Western Interior... Quiet weather for the most part, with some inland stratus and patchy fog through today. Thereafter, the flow becomes strongly out of the north over the coast, bringing gale force wind gusts into the Yukon Delta, Saint Lawrence, and most of the Seward Peninsula. Expect snow squalls/showers to be very active across the Yukon Delta and Saint Lawrence, as well as over the Bering Coast. North winds will gradually slacken Saturday. North Slope and Brooks Range... Active weather pattern as more snow is on the way. The first wave of accumulating snow will move over the eastern Arctic Coast tonight, with heavier snow spreading west to Umiat and Barrow Saturday. Expecting potential accumulations of 6-9" of snow over the eastern Arctic, which will include the Dalton Highway. Expect some areas of blowing snow over the eastern Arctic where northeast winds will increase into the 20-30 mph. Coastal Hazard Potential Days 3 and 4...There is increasing threat that a west coast low will bring some elevated waters to Norton Sound and the Yukon Delta Tue and Wed. Strength, track, and impacts are harder to call. For now, the threat is noted, but the impacts do not look significant at this time as the storm is not overly strong. Stay tuned. && .HYDROLOGY... None. && .AFG WATCHES/WARNINGS/ADVISORIES... Winter Weather Advisory for AKZ222-AKZ225. Winter Storm Watch for AKZ203-AKZ204-AKZ206-AKZ223-AKZ224-AKZ226.
