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. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxak68 pafc 231253 afdafc southcentral and southwest alaska forecast discussion national weather service anchorage ak 453 am akdt Fri jun 23 2017 Analysis and upper levels The semi-blocked pattern continues this morning as the upper level dirty ridge slides toward the canadian yukon. A couple shortwave troughs in the northern stream are facilitating this move as the approach the southwestern mainland. The ridge is also getting squeezed from the south as another shortwave rolls up on the east side of a long wave trough. General high pressure sits over most of the mainland at the surface with light winds. Convection over the copper river basin and canadian yukon keeps plentiful cloud cover under the ridge, while up-inlet flow has brought low-level clouds and even a little drizzle from kenai northward up into the susitna valley. Model discussion The general synoptics of the upper pattern are well agreed upon. However the evolution of the upper trough over the gulf, and the incoming shortwave have introduced some differences among guidance. The ooz and 06z runs have come into better agreement with this feature but it will have big ramifications on convection in the copper river basin on Saturday. Aviation Panc... Marine layer stratus will linger around the cook inlet region and slowly lift through the day. There is a chance for lower ifr conditions to exist this morning, but they should be transient and not widespread. Short term forecast southcentral alaska (days 1 and 2) With the upper level ridge beginning to retreat to the east and a low moving northward toward the gulf of alaska, the pattern is beginning to slowly change. This should mean that today will be the last for the persistent low stratus in the upper cook inlet region with a possibility of marked improvement as early as this evening. This will allow temperatures to rise back toward normal for Saturday and above normal for Sunday when there will be a break between systems. There remains the possibility for a few thunderstorms over the talkeetna mountains and into the copper river basin this afternoon and evening as well as tomorrow, but there should not be anything widespread. Short term forecast southwest alaska (days 1 and 2 Fri and sat)... the convergence zone hung up along the kuskokwim mountains lived up to its billing. Light rain with some embedded convection was apparent across the area through the night. It has also seemed to cause just enough mixing to keep the dense fog from forming in the delta and bristol bay as it did Thu morning. We are still expecting some patchy fog marine stratus to move inland along the coast, but it should not be nearly as dense as yesterday. That boundary will not move much through the day, and in fact, it will help to serve to focus some more isolated thunderstorms in the region late this afternoon through the evening. Further to the east, weak ridging will give way to more influence from a strong |
low in the gulf of ak later today into sat. But first, another round of isolated thunderstorms are expected along the northern portion of the ak range this afternoon-evening. These storms should move to the west and could work in tandem with the aforementioned boundary to make for a bit more widespread convection over the lower kuskokwim valley. As the low in the gulf works northward into sat, it will allow flow to switch to more northeasterly across bristol bay and the lower kuskokwim valley. This will result in warming temperatures with more sunshine (after the patchy fog burns off) for these areas. However, with the thermal trough still present, another round of thunderstorms along the terrain is expected. Meanwhile, across the delta, onshore flow will persist and could lead to another morning of marine stratus and fog, especially along the coast. While skies should clear during the day with ridging building in, temperatures will remain quite a bit cooler than the rest of the SW mainland. Short term forecast bering sea aleutians (days 1 and 2 Fri and sat)... a broad area of low pressure will dominate the bering as it pushes weak high pressure to the east into the weekend. High pressure is trying to hold on over the eastern bering for the next 48 hours. Under it, there is fairly widespread marine stratus patchy fog with very light winds. But the big weather maker will be the low currently near shemya. This low will hold right on the northern edge of the sub-tropical jet for the next several days. So as pieces of energy ebb and flow along the jet axis, the low will constantly undergo modifications to strength and location. But overall, it will drift to the east. As it does so, it will bring steady rain and sustained small craft winds to the central aleutians. Conditions will be a bit more showery and gusty for the far western aleutians as some cool air starts to wrap in behind it by late Saturday. Long term forecast (days 3 through 7) An amplifying longwave pattern looks to bring and end to the period of nice weather over much of southern alaska early next week. By Tuesday, the upper level trough over the bering sea will dig southward and begin tapping into some moist subtropical air while advecting that air northward into the gulf of alaska. This looks to set up a rather wet period for much of southern alaska Tuesday through Friday of next week as a series of systems move into the gulf of alaska and north toward the gulf coast. There is pretty remarkable model agreement with this change in weather pattern so confidence continues to rise. However, it is to be expected that there could be some breaks in the rain and clouds but overall, wet and cloudy will be the theme for much of next week. Afc watches warnings advisories Public...
