Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 312 PM AKDT Fri Jul 3 2020

SYNOPSIS. A stalled front will bring some rain showers to the western and central Interior this evening. Chances for showers will dissipate overnight. A ridge building over the west coast and the Interior tonight will bring a warming trend in temperatures for Saturday and Sunday. We expect fog and low ceilings at times tonight along the north of the Bering Strait.

DISCUSSION. The 03/12UTC model suite generally initialized well when compared to observations. The models are in good overall agreement out through the weekend. By Monday night, agreement between the different operational models breaks down. We opted to lean more heavily on the NAM for the short term forecast.

Aloft, at 500 mb, a 544 dam low is currently over Mackenzie Bay. This low will very slowly slide to the southeast through the weekend. A ridge will build north over the west coast and the western Interior tonight. A low diving south from the Arctic looks to knock the ridge down south Sunday night and Monday. The models are hinting at a low moving across the Bering Sea reaching the west coast by the middle of the upcoming week; however, the models differ on the details of this.

Central and Eastern Interior: Scattered showers are expected this evening west of Fairbanks along a stalled front. Shower activity will diminish after midnight tonight as a ridge builds in aloft tonight. The ridge will bring a slight warming trend in temperatures for Saturday and Sunday. Gusty northerly winds are expected at times on Saturday north of the Yukon River, with the strongest winds expected near the Brooks Range. A southward moving shortwave associated with a low over Mackenzie Bay will provide a forcing mechanism for scattered showers and thunderstorms on Saturday south and east of Fairbanks. On Sunday, showers and thunderstorms will primarily be confined to areas southeast of Delta Junction. Chances for precipitation look to increase on Monday.

West Coast and Western Interior: Rain showers associated with a front in the Western Interior will diminish this evening as the weather front continues to weaken and pushes into the Central Interior. As the front dissipates, high pressure will move in across the area. High pressure will bring a warming trend in temperatures and dry conditions to the area tomorrow. Coastal areas north of the Bering Strait will see a mixture of fog and low clouds tonight into Saturday morning. A front will bring increased chances of precipitation to the west coast Sunday night, before moving east into the Western Interior Monday morning.

North Slope and Brooks Range: A strong area of low pressure east of Demarcation Point will cause winds gusty northwesterly winds this evening east of Point Thomson. This low will move east overnight, and high pressure will build back over the area overnight causing winds to die back down and become northeasterly again. Low stratus and fog are expected to return to areas along the coast tonight.

In the extended periods, model agreement really diverges after Sunday; however, in general, the models are hinting at below normal temperatures and increased chances for showers south of the Brooks Range.

Coastal Hazard Potential Days 3 and 4 . None.

FIRE WEATHER. A weather front will bring chances for showers to areas west of Fairbanks this evening, with chances for showers diminishing after midnight. Temperatures will be slightly warmer on Saturday for most locations as high pressure builds over the area. Temperates will be similar on Sunday. Isolated to widely scattered thunderstorms are expected east of Fairbanks on Saturday. On Sunday isolated thunderstorms are expected southeast of Delta Junction.

HYDROLOGY. No major concerns at the moment. Rivers in the eastern Interior will continue to fall through the weekend.

AFG WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory for PKZ245.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
