SYNOPSIS. Strong east winds gusting to 45 mph across hills of the Northern Interior will persist through tonight. East winds gusting to 45 mph along the Tanana River near Delta Junction will persist into Sat. Freezing rain over the southern Yukon Delta will end early this morning.
Temperatures, currently well above normal, will cool slowly through Fri, then warm on the weekend as southerly Chinook winds develop over the Alaska Range.
Aloft . The long wave pattern now consists of a strong high over Northern Alaska and a trough over the Bering Sea and Gulf of Alaska. Several weak short waves will move from the southern Yukon Territory and Northern Gulf of Alaska NW across the Interior Alaska and then exit from NW Alaska. As these short waves move NW, the long wave trough in the Gulf of Alaska will weaken. A deep low aloft in the NW Pacific will move east over the Bering Sea in Fri, and over the Bering Sea and Western Gulf of Alaska by Sat. This will in turn cause a ridge aloft to build from the Eastern Gulf of Alaska north over Eastern Alaska by Sat, and persist into Sun and Mon. What this means is that the southeast flow aloft over Interior and West Coast of Alaska will turn more southerly on the weekend and cause a warmup to well above normal on the weekend.
One short wave trough along the West Coast of Alaska will move to the Dateline by 3pm Thu then continue NW. Mid-level clouds and gusty winds associate with this trough will move NW with the through.
A second short wave over the Yukon Territory will move over the SE Interior this evening, to Tanana to Eagle by 3am Fri, to Kotzebue to Fairbanks by 3pm Fri, and NW of the NW Coast of Alaska by 3am Sat. Expect another round of gusty winds with this feature,
Surface . Strong high pressure over the NWT of Canada with a ridge north over Banks Island and another ridge west over the NE Interior will persist through Fri am, then weaken.
A low pressure trough from Cape Lisburne to a 1000 mb near Point Thompson will persist through Fri, and then move north of the Arctic Coast of Alaska Fri Night and Sat. This is causing Easterly gales NE of Barter Island that will weaken slowly this afternoon into Fri. There are also areas of flurries and fog along the trough that will persist into Fri. The winds along the coast will turn SW and weaken Fri PM as the trough moves offshore. Fog and Flurries will move offshore as well.
A low pressure trough over the West Coast of Alaska will move west along the Dateline by 3pm Thu, and then continue moving west Thu night. This is causing easterly gusty winds along the West Coast now that will decrease this afternoon.
A 987 mb low near Nunivak Island will move to near St Matthew Island as a 990 mb low by 3pm Thu, and to near Cape Navarin of Russia as a 991 mb low by 3pm Fri. A weather front stretching southeast from this low will move to Cape Navarin to Nunivak Island by 3pm Fri, then move to St Lawrence Island to the Yukon Delta by 3am Sat, and to the Chukchi Sea to Anvik by 3pm Sat. Expect light snow along the front to move north over the West Coast with the front Fri and Sat. Could see 1-2 inches of snow.
A very strong low in the Gulf of Alaska will move to the Kenai Pen Fri night and weaken. An occluded front with this low stretches along the Gulf of Alaska Coast and moves to Along the Alaska Range by 3pm Thu, and then to McGrath to Eagle by 3pm Fri and dissipating. This will spread a chance of light snow to the SE Interior this afternoon into Fri. This front is also causing a strong surface gradient over the Northern Interior now between it and the high pressure Ridge over the NE INterior. This strong gradient will persist into Fri am and then weaken as the front and ridge weaken. This is now causing east winds gusting to 40 mph from Finger Mountain to Shungnak that will last into Fri am. It is also causing east winds gusting 30 to 40 mph along the Tanana River from Delta to Nenana that will last through the Day Fri, and possible into Sat. This will also cause east winds gusting to 25 mph near Eagle from this evening into Fri night.
A very strong low will move north into the Southeast Bering Sea Fri night and Sat. This will cause weak chinook winds across the Alaska Range Fri night that increase on Sat and last into Sun. This will also bring a chance of snow to zones 214 and 215 Sat, with east winds increasing along the West Coast Sat night and Sun.
DISCUSSION. Models initialize well aloft at 00Z, and show similar solutions through Sat. Models show similar precip fields through Thu night, then on Fri the NAM and ECMF bring precip north over the West Coast faster than the GFS. At this time favor a blend of the NAM and ECMF for precip location, but will only indicate flurries over Interior Alaska in locations where there are currently stratus clouds.
Models verify well at the surface at 06Z, except that there is a stronger surface low near Barter Island than models indicate. Since there is currently open water just offshore of Barter Island, expect this to act as a heat source to keep this thermal low in place, and expect a stronger low pressure in the area to remain through Sat than models indicate, which will result in stronger gradient and winds than models indicate over the Eastern Brooks Range and Barter Island area.
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.

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.
