Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 224 PM AKDT Wed Aug 12 2020

SYNOPSIS. Showers and isolated thunderstorms are expected in the Eastern Interior this afternoon as a weak upper level low near Circle weakens in place. Some stratus is hanging around in Norton Sound, but otherwise mostly clear skies in the Western Interior and West Coast. A cold front will traverse west to east across the Arctic Coast bringing low stratus especially from Utqiagvik west. Moving into the end of the week and weekend, a building ridge will lead to sunny, warmer, and drier weather throughout most of Northern Alaska.

DISCUSSION.

Upper Levels and Analysis . 12z models initialize well with the major feature being a longwave trough over all of mainland Alaska anchored by a 5540 meter height closed low centered over Skwentna. Additional closed lows are present over the Western Aleutians, NW of Wrangel Island, and over interior British Columbia. Models are now in agreement that the closed low NW of Wrangel Island will retrograde to the north and west, rather than progress eastward nearing the Arctic Coast. This opens the door for a ridge currently over the Western Bering to build over Northern Alaska toward the end of this week and hold in place through the weekend. The highest heights will remain over the Bering Sea and West Coast, with precipitation and isolated thunderstorms still possible over the far SE Interior as the longwave trough and associated thermal trough progress to the east and slowly weaken in place.

The ECMWF and Canadian are stronger than the the NAM and GFS with the ridge over the West Coast, while the GFS and the NAM spread the ridge further north and east. Aside from this difference, models are generally in excellent agreement as we head into a quieter, warmer, and drier pattern. The next disturbance looks to be a strong shortwave moving into the SE Interior on Sunday night and Monday, though models do not yet agree on the strength and position of this feature. The ECMWF has been consistent in its handling of the closed low NW of Wrangel Island, and generally looks like the best solution through the weekend.

Models show similar areal coverage for precipitation, other than the NAM showing widespread light precip over the Bering Sea Thursday through Friday. We will use a blend of the NAM/GFS and ECMWF for precip areal coverage and precip amounts, excluding the NAM precip over the Bering Sea Thursday through Saturday.

At the surface at 15z, models verify well on most features, except that the thermal trough from Ruby to Circle and east is 2 mb deeper than models verify. This may lead to slightly more convection over the Yukon Flats this afternoon than most models indicate due to stronger convergence along this trough, and also because this is the area with the highest moisture levels, while moisture west of Livengood is more limited. Otherwise models show similar solutions through 4pm Thursday. After that time, models differ on location and strength of lows moving north of the Russian coast near Wrangel Island, but over Alaskan waters and NW Alaska all models indicate winds less than 20 knots with the exception of right at Cape Lisburne which has SW winds 25G40 mph today through Friday.

Central and Eastern Interior . Showers and isolated thunderstorms are expected today and tomorrow, otherwise expect a warming trend heading into the weekend with mostly clear skies and high temperatures in the 70s. The exception will be the far SE interior where showers and isolated thunderstorms may persist into Friday and showers through the weekend as a thermal trough associated with the longwave trough lingers.

West Coast and Western Interior . Mostly clear skies and warming temperatures through the weekend are expected. Some low stratus may linger in and around Norton Sound through Friday, but expect little in the way of clouds inland with light winds and highs in the 60s and 70s as a ridge over the Bering builds eastward.

North Slope and Brooks Range . Several weather fronts moving east across the North Slope will bring periods of rain to the Arctic Coast the next several days, with periods of warmer conditions in between. Expect pleasant conditions in the Brooks Range with just a chance of rain in the Central and Eastern Brooks Range on Friday with the passage of a surface low from NE to SW.

Coastal Hazard Potential Days 3 and 4 . None

FIRE WEATHER. Showers and isolated thunderstorms are expected this afternoon and tomorrow in the Eastern Interior and Alaska Range, mostly associated with a weak upper level low near Circle that is gradually weakening in place. The West Coast and Western Interior will remain mostly clear. A warming and drying trend will prevail moving into the end of the week and the weekend as a ridge builds from west to east over all of Northern Alaska. A few isolated thunderstorms are possible in the far SE Interior on Friday, but otherwise expect clear skies with high temperatures in the 70s for much of the Western and Central Interior from Thursday through the weekend. Mins RHs will drop to the 40% range from west to east through the weekend while overnight recovery will remain excellent under mostly clear skies.

HYDROLOGY. Heavy rainfall earlier this week over the Eastern Alaska Range north to Eagle Summit and Coal Creek has creeks and rivers draining this area running high and fast, though flooding is not expected. This water will eventually all come through the Tanana River, which will remain near bankfull near Fairbanks through Thursday. This heavy rain has also caused a sharp rises on most Eastern Interior rivers including the Salcha, Fortymile, Charley, and Goodpaster, but those are also expected to remain below flood stage.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
