Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 518 AM AKDT Mon Apr 19 2021

SYNOPSIS. Another warm day expected across the Interior as ridging hangs on. A strong cold front will move south across the Arctic coast today and to the eastern Interior Tuesday, bringing increased northerly winds, snow and blowing snow to the eastern half of the Northern Slope and Brooks Range as winds increase into the 30 to 40 mph range. South of the Brooks Range, highest snowfall amounts will be south and east of Fairbanks Tuesday. North winds will also increase into the 30 to 40 mph range in the Alaska Range passes Tuesday and Tuesday night. Warmer and drier conditions expected once again by midweek.

DISCUSSION. Models . The 19/00Z model solutions initialized fair overall against the 00Z and 06Z surface obs as well as the 00Z RAOBs. Models continue to undercut the strength of the ridge over British Columbia and the Yukon Territory. Models are in agreement showing a strong shortwave pushing south and east across northern Alaska today and Tuesday with ridging building east across mainland Alaska behind it. Given that the ridge is stronger than what models indicate, it is likely that the shortwave will be a little slower to move eastward. The GFS and NAM seem to capture this better than the ECMWF and Canadian. NAM captures the winds best across the eastern Beaufort Sea coast so will lean towards it for winds. For precip went with a GFS/NAM blend. General model blend for other variables.

Upper Levels and Analysis . Ridging extends westward across much of mainland Alaska this morning, while a strong shortwave approaches the northwest coast. As the shortwave slides south and east across northern Alaska today and Tuesday, the ridging will be flattened with energy centered over Chukotka and British Columbia. Behind the shortwave, ridging quickly builds eastward across the Bering Strait by Wednesday morning and into the western Interior by Wednesday afternoon.

At the surface, a strong cold front will accompany the shortwave, bringing colder temperatures, snow chances, increased winds, and areas of blowing snow as it traverses northern Alaska. High pressure building in behind it will usher in another round of warmer and quieter weather.

North Slope and Brooks Range . A strong arctic front will push across the Arctic Coast today, resulting in increasing westerly winds, snow, blowing snow, and an accompanying shot of colder air. Strongest winds expected along the eastern Beaufort Sea coast where the pressure gradient will be the tightest as high pressure builds east north of the Brooks Range. West winds gusting to around 50 mph will cause blowing and drifting snow and blizzard conditions are expected Monday night and Tuesday. The Winter Storm Watch has been upgraded to a Blizzard Warning. A Winter Weather Advisory remains for the Dalton Highway passes, where north winds gusting to 45 mph will cause blowing and drifting snow and reduced visibilities. Winds diminish by Tuesday afternoon in the Brooks Range passes and by Wednesday for the eastern Beaufort Sea coast.

West Coast and Western Interior . A strong front pushing across the northwest coast today will tighten the pressure gradient along the coast and St Lawrence Island, increasing northerly winds. Wind gusts to 50 mph possible across St Lawrence Island and into the Y-K Delta. Strong wind headlines are in place for most areas south of the Seward Peninsula, with the exception of the southern Seward Peninsula coast, where winds will be 15 to 30 mph. Some blowing snow is possible, although most locations have probably crusted over the top of the snow layer. Winds diminish Tuesday as high pressure builds in, with warm and dry conditions prevailing.

Central and Eastern Interior . Another warm day is on tap today across the Interior. Southerly gap winds expected in the Alaska Range passes today and tonight with gusts of 35 to 40 mph. A strong cold front pushing south across the Brooks Range will bring cooler temperatures to the Interior, as well as snow chances from the Upper Tanana Valley to the Alaska Range and across the Fortymile Uplands Tuesday. Highest snowfall amounts will be east and south of Fairbanks. North winds will begin to increase across the southeastern Brooks Range this afternoon and evening, peaking overnight, and diminishing during the day Tuesday. While winds increase, snow chances will be low due to some downsloping on the south side of the Brooks Range, and while blowing snow is still expected, visibilities of half a mile or less are not anticipated at this time. In the Alaska Range, north winds develop Tuesday morning, peaking Tuesday evening. Some blowing snow is possible, but low visibilities are not expected. Tuesday will be the coldest day of the week with highs largely in the 30s and 40s and lows Tuesday night in the teens. Temperatures warm once again Wednesday as high pressure builds in.

Extended Period Forecast Days 4-7 . Ridging aloft will continue to build across the mainland through the week. Another round of warming temperatures and dry weather is expected as high pressure dominates through the weekend.

Coastal Hazard Potential Days 3 and 4 . None.

FIRE WEATHER. None.

HYDROLOGY. Snow pack continues to ripen south of the Brooks Range. Will see limited melting through mid-week, with melting increasing late in the week.

AFG WATCHES/WARNINGS/ADVISORIES. Blizzard Warning for AKZ204.

Winter Weather Advisory for AKZ206.

Gale Warning for PKZ210-PKZ245.

Brisk Wind Advisory for PKZ200-PKZ215-PKZ220-PKZ230-PKZ235- PKZ240.
