Marine Weather and Tides Clark's Point, AK Version 3.4

What's New / NOTES 5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Fxak68 pafc 200053 afdafc southcentral and southwest alaska forecast discussion national weather service anchorage ak 453 pm akdt Tue jun 19 2018 Analysis and upper levels The upper level pattern has changed very little from yesterday with the large upper level low in the eastern bering sea. The 250 mb jet stream remains well south of the aleutians and then turns due south-to- north through the gulf of alaska and then to the alcan border. What has changed is the surface low is now nearly vertically stacked under the upper level low and has weakened considerably. What remains of the front with this low stretches to near the bering strait and then toward the brooks range. This has allowed the pressure gradient over southern alaska to ease and reduced the winds. The atmosphere in southwest alaska is a little more unstable today being close to the cold core of the upper level low center. This is allowing some showers to pop-up this afternoon as well. Model discussion Models remain overall good agreement the next few days. The wave that will develop in the gulf of alaska and move onshore Wednesday evening through Thursday is farther west on the NAM and GFS than canadian and ec models. The more open-wave structure of the nam GFS seems more reasonable and was used for guidance in the gulf and southcentral areas. Both GFS and NAM are indicating an uptick in instability tomorrow for the kuskokwim delta and far north copper river basin as compared to previous runs. Aviation Panc...VFR conditions will persist. Some southeast winds may move over the terminal this evening into the overnight hours, but should be much less than past days with winds being only being in the 10 to 15 kt range. Short term forecast southcentral alaska Moist southerly flow aloft will continue through Thursday as the synoptic pattern of an upper level low over the eastern bering and ridging east of southcentral alaska remains in place. This pattern will bring showery conditions to southcentral alaska that will be amplified as various shortwaves move through the upper level flow. One shortwave is pushing through the kodiak island area bringing rain to the island that will last into Wednesday. Another will push in over the kenai peninsula late Wednesday bringing more rain to the area. It will then track north spreading rain to areas from the susitna valley through prince william sound Wednesday night into Thursday. Showers will then diminish moving into Friday. Short term forecast southwest alaska (days 1 through 3) With the upper low persistently centered offshore of southwest alaska, southeasterly flow at the surface and southerly flow aloft will continue to stream moisture up into southwest alaska, with small troughs rotating around the main low further enhancing precipitation. The next of these shortwaves will lift north across the western capes and kuskokwim delta this afternoon and

evening followed another trough further inland tracking the greater bristol bay and kuskokwim valley late tonight and Wednesday morning. By Wednesday afternoon afternoon and evening a broader trough rotating through and increasing general instability will support showers across all of southwest alaska. Additional troughs will continue spinning across the area through the end of the week before the entire pattern starts to shift north. Short term forecast bering sea aleutians (days 1 through 3) The upper level low centered over the eastern bering, alaska peninsula and bristol bay area will remain in that general location through Thursday before beginning to drift north Thursday night and Friday. Troughs rotating south around the backside of the low will move through the pribilof islands and eastern aleutians while further west the general flow remains diffuse and out of the west northwest through Thursday. On Friday, a frontal system will approach the western aleutians. Long term forecast (days 4 through 7) The long term forecast begins Friday night with the persistent long-wave trough anchored over the eastern bering western alaska. Upstream, an elongated ridge extends across the canadian rockies north into the yukon and eastern alaska. Between the two, an upper-level shortwave is moving northward through the gulf of alaska. A more potent upper-level disturbance and surface low in the northeast pacific is continuing toward the alaska peninsula. Models are in fairly good agreement with the track of the low moving toward the alaska panhandle for the weekend. As it does, a surface ridge will lift northward across the gulf and into southern and southwest alaska for Saturday, reducing any residual onshore flow and producing a warming trend for the weekend. However, the aforementioned shortwave will also move across the region, providing enough instability to generate clouds and showers. Scattered clouds and showers continue into Sunday as a second, weaker shortwave moves through the interior of southern alaska. The overall pattern becomes more progressive by the end of the weekend with a zonal jet stream south of the state bringing two lows across the aleutians toward the northern gulf. The first will slide from the western aleutians Saturday to the gulf by Monday evening. The second will approach the central aleutians by Tuesday afternoon. Although it is still a long way out and there is significant model divergence by early next week, there is some indication that the development toward a more progressive pattern by the end of the weekend could shift the longwave pattern and kick the persistent upper-level low over the bering to the east.

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.
