What's New / NOTES 6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. 5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Fxak68 pafc 241259 afdafc southcentral and southwest alaska forecast discussion national weather service anchorage ak 459 am akdt Sun sep 24 2017 Analysis and upper levels A low pressure system is currently located over southwest alaska and contains two distinct low centers. The first low is located just east of kodiak island at 993 mb while the other low is located over bethel at 994 mb. An occluded front has formed on the north side of the low and is draped along the north gulf coast down to the eastern kenai peninsula, bringing heavy rain to locations along the coast. Southeasterly cross-barrier flow is leading to downsloping across the anchorage bowl and the northwestern kenai peninsula, limiting precipitation in those areas. Precipitation is also wrapping around the low over southwest alaska bringing rain and showers from the west coast east into the lower kuskokwim river valley. Further west, a ridge of high pressure is located to the southwest of the western aleutians and nudging east into the bering. Model discussion Models are in relatively good agreement through the first 48 hours showing the progression and dissipation of the two surface lows in the gulf and bristol bay. By Monday night, all models depict a low moving up into the gulf from the north pacific. Numerical guidance begins to differ at this point with the ec being the outlier as it moves the low center up towards kodiak by Tuesday morning while the nam, gfs, and canadian models were a bit slower and further south by Wednesday. Therefore, forecasts leaned heavily on the GFS nam guidance over the ec. Aviation Panc... Patchy low stratus and fog will be present in the anchorage bowl through the morning hours due to weakening southeasterly flow over the chugach and abundant moisture in the boundary layer from the previous day's rain. Fog was present as far south as merill field overnight before retreating back north and slowly diminishing, keeping the anchorage terminalVFR.VFR countdowns will prevail through the day as weak southeasterly flow continues to keep most of the precipitation over the mountains. Fog and low stratus may develop again tomorrow night as the flow switches to up inlet. Short term forecast southcentral alaska (days 1 and 2) The weakening low over the western gulf will continue to bring rainfall to much of the gulf coast, but with a weakening barrier jet no significant winds are expected. Rainfall over southcentral is expected to redevelop one last time from this morning as the upper level shortwave passes overhead with weakening downsloping. One concern ahead of this shortwave will be with patchy fog that developed throughout the anchorage bowl late Saturday night. This fog will likely be the most dense and widespread along knik arm glenn highway, with patchy coverage expected elsewhere, but with some mixing from incoming rainfall widespread dense fog is however not expected. Rain and fog is then expected to break up by this afternoon as the upper level trough lifts to the north, leaving cloudy skies and the chance of a passing shower by this evening. Weak cyclonic flow aloft will keep generally cloudy skies throughout the area into Monday, however most of the shower activity should be confined to the gulf coast. There is the good possibility that fog stratus will redevelop throughout upper cook inlet tonight, especially as flow shifts to light southwesterly. The good news is that persistent upper level cloudcover should limit any significant or widespread development, though patchy areas should be expected again tonight into the Monday morning commute.

Short term forecast southwest alaska (days 1 and 2) A wet pattern persists through the beginning of the next work week as a low over the southwest lifts to the north and another low slides south across the eastern bering. Patchy morning fog develops during the mornings across inland areas as weak temperature inversions set up at night. Winds across the kuskokwim delta are expected to prevail out of the north with winds along the valley and bristol bay shifting from the south becoming east to northeast Monday night as a north pacific low moves closer to kodiak island. Short term forecast bering sea aleutians (days 1 and 2) A wetter regime ensues across the eastern bering and alaska peninsula as a low pressure system moves south along the eastern waters. This slow moving system is expected to cross over the peninsula by Tuesday morning on its track to the north pacific. A ridge holds across the western bering through early week advecting a cooler air mass along northerly flow. The central bering and eastern aleutians will see influences from both systems as low pressure across the eastern bering takes a slight westward shift... Primarily the pattern stays on the drier side for this area with increasing chances for rain as the low nears the peninsula. Long term forecast (days 3 through 7) Confidence continues to increase in regards to an area of low pressure quickly moving into the gulf of alaska from the north pacific on Tuesday. The ECMWF is the fast outlier currently but it now looks like gale force gusts could be expected near kodiak island and the northern gulf Tuesday afternoon through Wednesday afternoon as a front associated with the low pressure quickly moves through the region. Rainfall with this system will upslope along the coastal mountains but there is bigger question for interior locations and it really depends on the low track. Currently it looks like inland areas like anchorage and palmer may miss out on much of the precip on Wednesday. Looking at the big picture from late next week through the weekend, it appears the wet pattern across southwest and southcentral alaska will remain the norm. A jet streak on the backside of an upper level low over southwest alaska on Tuesday will help amplify the longwave trough across the state of alaska. This will keep cyclonic flow across the region with colder air being advected south which should keep increase instability and keep rain showers in the forecast for much of the state. There could be a few breaks with some shortwave ridging across southwest alaska over the weekend but zonal flow will return to the state by late Sunday and allow for another unstable pattern to develop across the state. Afternoon high temperatures look to remain below normal with low temperatures across the region remaining near normal. The majority of the bering sea will be under the influence of high pressure come Tuesday with low stratus and fog. By late Friday, a strong low will push off of russia and into the bering sea which will force the high south into the north pacific and a rather wet and windy period will be observed across the bering through the weekend.

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.
