Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 157 PM AKST Sat Dec 14 2019

SYNOPSIS. A period of relatively quiet weather is expected for northern Alaska through early next week. Southerly flow is producing gusty winds in the Alaska range today but winds will diminish by Sunday morning. Scattered snow showers will continue over Saint Lawrence Island and Norton Sound through Sunday. The pressure gradient tightens on the north slope producing strong winds by Tuesday.

DISCUSSION. The long wave pattern consists of a high amplitude ridge over Eastern Alaska and Western Canada and a high amplitude trough over the Bering Sea and North Central Pacific. Southerly flow over the Alaska range will weaken and become more southeasterly by Monday. Colder air will begin to filter into the Interior by mid week.

Surface . High pressure will persist over the Eastern Arctic through the weekend. A 990 mb low 50 NM west of Gambell will move to 150 NM west of Point Lay as a 1002 mb low by 3am Sun, then continue moving north. A strong low in the southeast Bering Sea will move into Bristol Bay Sun and then weaken into Mon. Another low will track across the Aleutians on Tuesday.

North Slope and Brooks Range . Quiet weather through the weekend with patches of low stratus and fog for the north slope. The pressure gradient will tighten up on Monday and winds will ramp up. Expecting East winds of 30 to 40 mph Monday into Tuesday. Will have to watch to see if there is enough blowing snow to reduce visibility.

Interior . Southerly flow is producing locally strong winds in the Alaska Range and near Delta Junction today. A wind advisory is in effect for zone 226 for southerly winds gusting to 50 mph through this evening. Winds are also gusting to 30 mph near Delta Junction. Winds will weaken tonight then pick up again Sunday night into Monday. Otherwise pretty quiet over the Interior will no precipitation expected. Turning colder by mid week next week.

West coast . Trough of low pressure will kick off snow showers for the Bering Strait and Norton Sound through Sunday.

Coastal Hazard Potential Days 3 and 4 . None.

AFG WATCHES/WARNINGS/ADVISORIES. Wind Advisory for AKZ226.

Heavy Freezing Spray Warning for PKZ210.

Brisk Wind Advisory for PKZ200.

GEOS Local Image of Alaska    EDIT
NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
