Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 206 PM AKST Sun Feb 23 2020

SYNOPSIS. Cold wind chills continue along the West and Northwest Coast from Kotzebue Sound north to Point Barrow. Wind chill advisories continue in these areas through Monday morning. The low wind chills will moderate on Monday morning as winds diminish. Well below normal temperatures will continue over the Northern Alaska through at least the middle of this week.

DISCUSSION. Aloft at 500 mb a sharp and cold trough currently extending from near Wrangel Island southeast to near Yakutat will push north and east over Northeast Alaska as an upper level ridge pushes north and east out of the Eastern Bering and Northern Gulf of Alaska over Southwest and South Central Alaska Monday and Tuesday. As the ridge builds north over Northern Alaska temperatures aloft will rise from around 22 below at 850 mb at Fairbanks this morning to near 12 below by Wednesday. As temperatures aloft rise and valley temperatures remain locked in an arctic airmass under mostly clear skies expect very sharp inversions to develop over the Interior.

On the surface, a 1032 mb high pressure ridge currently centered over Southwestern Alaska will continue to build in strength and push north and east over the Central and Eastern Interior as a 1044 mb high pressure by Monday. Weak low pressure over the southeastern interior that is currently producing light snow will continue to push north and east into the Yukon. A strong pressure gradient develops over the Western Interior and West Coast south of the Seward Peninsula between the 1044 mb high pressure system over the Eastern Interior and a 975 mb low that develops in the Northwestern Gulf of Alaska on Tuesday. Winds over these areas will increase producing gusty off shore flow while light winds are expected over northern portions of the Central and Eastern Interior. As the strong high pressure pushes east into Canada, a Tanana Valley Jet will develop late Tuesday and Wednesday in the Delta Junction area with sub advisory winds expected.

Models, continue to struggle with initialization with the 12z model suite initializing the surface low pressure system northwest of Wrangel Island 4 to 6 mb too high and the High pressure over southwest Alaska 1 to 2 mb too low. The net affect being again that the forecasted pressure gradient along the Northwest Coast and in the upper Tanana Valley was too week. Winds forecasts were enhanced several knots which will extend in time the Wind Chill Advisories surrounding Kotzebue Sound and along the Northwest Coast. The forecasted winds in the Upper Tanana VAlley were also increased as well as blowing snow included in the forecast with gusty northwest winds producing reduced visibilities in blowing snow. Model spread is considerable as far as both position and strength of synoptic scale features by the middle of the week.

Coastal Hazard Potential Days 3 and 4 . None.

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.

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.
