Fxak69 pafg 241449 afdafg northern alaska forecast discussion national weather service fairbanks ak 649 am akdt Fri may 24 2019 Discussion Aloft... a longwave trough continues to dominate over the west coast of alaska from the chukchi sea and south into the northern pacific ocean. High pressure is situated along the canadian border east of fort yukon this morning. A weak cutoff low southeast of cordova will move southeast today and be south of juneau by this afternoon. High pressure will build into most of alaska behind this low and remain in place throughout the weekend. A second cutoff low northwest of wainwright will move east and be north of kaktovik by early Saturday. Two merging longwave troughs in the bering sea will persist in and around bristol bay into the middle of next week. A series of shortwave troughs will come from the south early next week and slowly break down the ridge. Surface... a thermal trough situated over chalkyitsik will track to the northeast today. Scattered thunderstorms expected in this region due to the favorable environment of 500-880 j kg CAPE and lifted index between -1 and -2 this afternoon. A second low centered north of wainwright will move east and merge with a developing low north of kaktovik by this afternoon. As this low slides to the east, high pressure builds into norton sound today. The next feature of interest is a low tracking north from the northern pacific ocean beginning this afternoon. The low will continue to strengthen and be located northeast of atka by early Sunday morning. Chinook gap winds expected to develop late Saturday as the low continues to move north. Model consensus of location and intensity still undetermined at this point, but confidence is still high for a chinook event beginning Saturday evening and lasting into early Monday morning. North slope and brooks range... snow currently falling at point lay and wainwright, with dense fog from utqiagvik and east to deadhorse this morning. The surface low pressure northwest of wainwright will track east today, bringing isolated chances for rain and snow from point lay and east to utqiagvik. Weak high pressure builds in along the north slope Saturday afternoon, bringing partly to mostly cloudy skies with intermittent fog and low ceilings along the north slope through the weekend. West coast and western interior... dense fog occurring along the west coast and into kotzebue sound this morning. High pressure builds into norton sound today, with clearing skies throughout today and tonight. A strong low pressure from the south will break down the high pressure in place over norton sound beginning this evening. As this low continues to track north, models are in good agreement with the next chance for precipitation expected for the west coast and western interior by Saturday evening.

Central and eastern interior... a thermal trough is currently centered over chalkyitsik and southeast to eagle. Scattered thunderstorms expected in the eastern yukon flats today with frequent lightning, small hail, and gusty winds. As the trough moves northeast and dissipates this evening, thunderstorm chances in the interior diminish significantly into early next week. The approaching low into bristol bay this weekend will bring southerly flow to the mountains. Chinook gap winds expected to develop Saturday afternoon and last through Monday afternoon. Maximum winds expected to be occur Sunday morning and into the afternoon hours. Drier conditions in the interior expected tomorrow as the chinook gap winds begin to develop tomorrow. Coastal hazard potential days 3 and 4... None. Fire weather Thermal trough setup is centered around chalkyitsik and stretches southeast to eagle today. This trough will allow for isolated thunderstorms this afternoon from eagle to fort yukon. Scattered thunderstorms expected from chalkyitsik and east to the canadian border with frequent lightning, small hail, and gusty winds. The thermal trough is expected to dissipate for the weekend, with only isolated chances for thunderstorms around eagle on Saturday. Winds up to 15 mph sustained from indian mountain to fort yukon and north to the brooks range expected this afternoon, coincident with the thermal trough and maximum daytime heating. Chinook winds through the gaps will develop beginning Saturday afternoon and reach its peak early Sunday morning. High confidence on gap flow occuring but modest confidence on peak winds through isabel and windy passes as model spread is still large on the low pressure location and intensity in the eastern bering sea by early Sunday morning. Rh will remain above 30 percent today. A warming trend is expected over the weekend, leading to lower minimum rh values for Saturday, reaching below 25 percent in scattered locations in the central and eastern interior. Sunday is forecasted to be the warmest day in the interior for the near future. Minimum rh still hovering around 25 percent in most areas of the interior for Sunday. Hydrology Flood warning for rapid snowmelt continues for the koyukuk river at allakaket. Minor flooding of roads and outbuildings have been observed as of 8 am yesterday. The river is expected to crest over the weekend, with a slow retreat next week. Flood advisory remains in effect for rapid snowmelt along the koyukuk river downstream of allakaket to hughes. The river was observed to be rising and overbank at one end of the airport runway in hughes yesterday afternoon. High water and erosion expected to occur as the high water crests at huslia towards the middle of next week. Afg watches warnings advisories Brisk wind for pk240 and pk245. May 19

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.
