Fxak69 pafg 242245 afdafg northern alaska forecast discussion national weather service fairbanks ak 245 pm akdt Sun sep 24 2017 Discussion The models are in overall good agreement out through the middle of the week. The main weather concern today will be the potential for precipitation Monday in for the interior as well as the north slope and brooks range. Aloft, at 500 mb, a 531 dam low will persist over bristol bay before starting to to move south Monday night. A shortwave associated with this low will sit over the southeastern interior tonight into Monday. A trough associated with a low in the high arctic will move from west to east across northern alaska tomorrow into Tuesday. While the models agree on the timing of this trough moving across the state, they differ on how cold the air is aloft the NAM has temperates a few degrees colder at 850 mb than the gfs or the ecmwf, particularly in the northern portions of the interior on Monday night. This will in turn have some impact on snow levels Monday night in the northern interior. An upper level ridge will build over the chukotsk peninsula on Monday and over the west coast of alaska on Tuesday. A shortwave moving eastward through the chukchi sea will help to knock this ridge southward Tuesday night. The aforementioned shortwave will move across the arctic coast on Wednesday. An upper level ridge will build along the canadian border Wednesday into Thursday. At the surface, a 998 mb low near bristol bay will persist through Monday, gradually weakening. A cold front will move across the arctic coast of alaska Monday into Tuesday. An area of high pressure will build east just north of the brooks range Tuesday behind the front. This area of high pressure will push east on Tuesday night as a low pushes across the chukchi sea well north of the coast. High pressure will build over the chukotsk peninsula tonight, this will strengthen the pressure gradient over the bering strait and northern bering sea for tonight and tomorrow. Central and eastern interior: a front will move in to the interior this evening and stall. The front is expected to stall along a line from circle to fairbanks to mcgrath. Precipitation is expected along this front from this evening through early Tuesday morning with the heaviest precipitation expected early in the day

on Monday. An upper level trough associated with a low in the high arctic will spread colder air aloft tomorrow and tomorrow night. This will cause snow levels to drop between now and Tuesday morning. Snow levels this evening across much of the interior will be around 5000 feet and by Tuesday morning the snow level drop to 1000 to 2500 feet (higher from fairbanks south). Current thinking is that the precipitation type will mainly be rain tonight and Monday (with the main exception being above pass level in the alaska range). On Monday night in areas above 2000 feet the precipitation type will change to mix of rain and snow and by early Tuesday morning to all snow. Fortunately the precipitation will be tapering off by early Tuesday morning. Up to three inches of snowfall is possible along the steese highway at eagle summit Monday night. Conditions should clear up during the day on Tuesday. Another round of precipitation will move from southeast to northwest through the interior Wednesday night into Thursday. West coast and western interior: some precipitation is expected along a stalled front on Monday mainly for areas south of the yukon river. High pressure should keep things relatively quiet for Tuesday and Wednesday. There is some potential that a storm system will affect the west coast over the weekend; however, at this point, there is still a lot of uncertainty about the details of this given the differences between the models. Arctic coast and brooks range: a weather front will pass along the arctic. As this front passes through it will bring snow. Generally 1 to 2 inches of snow is expected as the front moves through in areas away from the coast. Lesser amounts are expected closer to the coast where rain is expected to mix in with the snow. Coastal hazard potential days 3 and 4... None. The models are hinting at the potential for a storm affecting the west coast next weekend; however, at this point, there is still a lot of uncertainty about the details of this given the differences between the models. Hydrology No issues anticipated at this time. Afg watches warnings advisories Small craft advisory for pkz200-pkz210-pkz220. Sep 17

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. 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.
