(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxak69 pafg 192355 afdafg northern alaska forecast discussion national weather service fairbanks ak 355 pm akdt Sat aug 19 2017 Discussion No major change to 19 12z 500 mb pattern with long wave troughing centered over mainland alaska, consisting mainly of a 533 dm low located around 50 miles west of kotzebue. Several short waves are embedded within this low. The first of which was seen rotating around the south periphery of the upper low moving across the gulf coast. A second low short wave with a 534 dm low center was located near the high arctic around 78n 150w, merging with another 535 dm low near 79n 174e that is moving east out of the siberian arctic. A 560 dm low was located south of the aleutians around 185 miles south of adak, and a 545 dm low was located on the boarder of alberta and the NW territories in canada. At the surface, the main weather pattern was dominated by broad low pressure remaining over mainland alaska, with several embedded weaker lows embedded in the long wave upper trough, including a 1000 mb double low located around 100 miles south of the eastern aleutians and a 995 mb low in the high arctic near 81n 153w. Weak 1016 mb ridge of high pressure was building over the bering sea and far east siberia extending north into the chukchi. The 12z deterministic models are in good agreement on the overall pattern through the remainder of this weekend into much of next week, although the guidance is trending slightly slower with the progression of the main features. Overall, the weather pattern will remain unsettled with periods of rain or showers, although there will be some dry breaks at times. Main upper low west of kotzebue will drop south across the west coast tonight, to be located over the alaska peninsula by Sunday evening, and into the gulf late Sunday night. The eastern upper low in the high arctic will eject to the north toward the north pole, as the other upper low moving out of the siberian arctic will take its place and remain nearly stationary through Monday to gradually drift north on Tuesday. A second short wave that will move out of the siberian arctic has sped up considerably with 12 18z guidance runs, now expected to move across wrangel island on Sunday evening, to cross the chukchi and move over the northwest coast by Monday evening, as short wave ridge builds over the southern bering at this time. North slope brooks range: no major concerns at this time. Scattered rain showers are expected for the brooks range tonight, greatly tapering off in coverage for Sunday as ridge over western alaska strengthens. Snow levels tonight and Sunday will range from around 2500 feet over the western brooks range to around 4500 feet for the eastern half of the range. A weak disturbance will move north from the east interior tonight, which will bring a round of rain the east brooks range from the dalton highway east to arctic village. Mainly snowfall is expected for atigun pass with minor accumulations expected by late Sunday night. Easterly flow with a weak ridge of high pressure over the eastern beaufort sea will promote periods of fog and stratus to persist through this weekend, and over the eastern arctic coast possibly through Monday. Ifr for and stratus will diminish as winds will shift offshore from west to east across the arctic coast beginning Sunday night, as a weak surface low will pass just south of wrangel island Sunday afternoon and move onto the western arctic coast somewhere between point hope and point lay by early Tuesday. |
A weather front will extend in front and to the south of this low, which will bring another round of rain to the western arctic coast and western brooks range Sunday night into Monday. The advancing front will bring a chance of rain Monday night into Tuesday for the eastern half of the north slope and brooks range. Showers will wrap around the low circulation over the western arctic coast and western brooks range on Tuesday, with snow levels falling to around 2500 feet. West coast west interior: the upper low will drift south as an upper level impulse rotates around the southern periphery of the low into the southwest interior. Periods of rain can be expected over the southwest interior late this afternoon into this evening, with lingering showers expected overnight. Scattered to isolated showers are expected for the remainder of the west coast, mostly from the seward peninsula south. Ridge of high pressure builds in the west coast late tonight and lasts through Sunday night. This will bring a brief period of rain-free conditions to most of the west coast and west interior Sunday. Short wave trough will quickly move out of east siberia Sunday morning, which will spin up a weak surface low to pass just south of wrangel island Sunday afternoon and move onto the western arctic coast somewhere between point hope and point lay by early Tuesday. A weather front will extend in front and to the south of this low, which will bring another round of rain to the chukchi sea Sunday night into Monday, and from the seward peninsula north on Monday. Lighter rain showers are expected south of the seward peninsula. Showers will wrap around the low circulation over the chuckchi sea coast and western brooks range on Tuesday, as the weather front advances bringing light rain to the west interior Monday night Tuesday. Central and east interior: scattered to numerous showers are expected for interior alaska through Monday. These showers will be diurnally enhanced, and isolated afternoon evening thunderstorms will be possible for the east interior through Sunday. A weak disturbance will move north from the east interior tonight, which will bring a round of rain to the southeast brooks from the dalton highway east to arctic village Sunday and Sunday night. Some locally heavy 24 hour totals up to 1 inch are a possibility, but it does not appear widespread enough to create major small stream flooding concerns. Some gusty winds will be possible through alaska range passes on Monday, but nothing significant with gusts expected to remain below advisory criteria. A weakening weather front moves into the central interior Tuesday, helping to refocus an area of light rain or showers here, to push into the east interior by Tuesday night. Coastal hazard potential days 3 and 4... A weather front will move through the chukchi sea on Monday. West northwest winds of around 20 knots behind the front will begin Monday evening to persist through at least Tuesday. The strength and fetch of the wind appears favorable enough for high surf and beach erosion in shishmaref during this timeframe, and trends will have to be watched closely for a possible advisory for this area. Fire weather No concerns at this time. Hydrology Flood advisory continues for the tetlin road, for the latest information go to |

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. |
