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. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxak68 pafc 240337 afdafc southcentral and southwest alaska forecast discussion national weather service anchorage ak 522 pm akdt Mon oct 23 2017 Analysis and upper levels An elongated upper level low centered along the kuskokwim delta has several short waves propagating about its center. One wave is currently moving north across the kenai with another downstream approximately 300 miles south of kodiak island. Another low is wrapping along the backside of this system diving south along the eastern bering. Ridging is separating this parent low from another parent system spinning along the kamchatka peninsula. At the surface, rain and snow is developing along a weak frontal boundary swinging north along the kenai. A few isolated thunderstorms developed along this front as is pushed north across the peninsula. This front produced a significant amount of snow as it moved along the aleutian range with 9" measured at iliamna airport. Offshore flow continues across southcentral with southeasterly flow returning along the eastern kenai. To the west, extratropical system lan is making its transition to the bering with heavy rain and gusty southeasterly flow gusting up to 60 mph at shemya this afternoon. Model discussion Models are generally in good agreement with the overall synoptic pattern, however they are struggling with handling the important weak dynamic features for evolving the precipitation forecast across southcentral heading into mid week. A blend was used from the operational models to update the afternoon package. Aviation Panc... A brief period of MVFR conditions is expected this evening as the front along the kenai moves north with snow along the boundary. Another front moves through on Tuesday, however kept low endVFR conditions at the end of the TAF package as the timing of this next system remains uncertain. Short term forecast southcentral alaska (days 1 and 2) An upper-level wave surface trough is progressing northeastward up cook inlet and the kenai peninsula this afternoon. The compact system will weaken as it moves to anchorage this evening, spreading some light snowfall over the anchorage and mat- su valleys area. Expect a quick shot of snow this evening that will taper off overnight. Attention then turns to the next upper-wave moving into kodiak island tonight. This feature will bring snow to the kenai peninsula by early Tuesday morning, moving north to the anchorage area late Tuesday morning early afternoon. At this point, there is quite a bit of uncertainty as to how much snow will make it into anchorage and the matanuska valley Tuesday. Recent model runs have shifted the track of the surface low further west, taking the low inland over the kenai peninsula or tracking it northeastward up cook inlet. This westward shift results in stronger southeasterly flow over the chugach mountains and turnagain arm, which would favor more of a downslope scenario over anchorage. The amount of snow that lower elevations of anchorage and the matanuska valley will see Tuesday is highly dependent on the timing and magnitude of these southeasterly winds. With the trend towards stronger southeasterly flow, keeping snowfall accumulations fairly low in lower elevations. The active pattern continues as a gale force front moves into the southwest gulf Tuesday night, then pushes to the central gulf and northern gulf coast by Wednesday afternoon. Behind this front, deep southwesterly flow will transport a significantly warmer moister airmass northeastward. Expect snowfall to transition to rain Wednesday morning over the bulk of southcentral, with high temperatures approaching the low 40s by Wednesday afternoon. Short term forecast southwest alaska (days 1 and 2) A weak upper level low to the north of SW ak will continue to pump moisture into the area leading to scattered snow showers along the bristol bay coast tonight. Accumulations will be no more than |
a few inches in most locations due to the spotty nature of the precipitation. Showers will gradually taper off late Tuesday morning before the next system moves in. A strong warm front associated with a deep low out in the bering will push ashore by early Tuesday evening brining copious amounts of moisture and much warmer air. Initially, precipitation will fall as snow but will quickly transition to rain along the coast before midnight. Warmer air will take a bit longer to reach inland locations leading to a more prolonged period of snowfall before changing over to rain by early Wednesday morning. Depending on the speed of the warm air moving in, there could be some noticeable snowfall accumulations along the upper kuskokwim river valley Tuesday night. Precipitation should taper off by Wednesday afternoon though persistent southerly flow behind the front will keep temperatures much warmer than what was seen across the area last week. Short term forecast bering sea aleutians (days 1 and 2) A very active weather pattern is in store for the bering and aleutians over the next couple of days. The remains of tropical cyclone lan over the kamchatka peninsula have combined with a strong north pacific jet to form the strongest low of season so far in the bering, with models deepening the central pressure to 935 mb as it approaches the western bering. Winds are already gusting to hurricane force at shemya and these winds are expected to spread east across the aleutians tonight and tomorrow. Though the low will be weakening as it traverses east, strong southerly winds associated with the warm front out ahead of the low will be channeled through terrain gaps, keeping the potential for hurricane force gusts along the northern side of the eastern aleutians and akpen. Thus, high wind warnings have been issued for the western aleutians through tomorrow morning and for the eastern aleutians akpen tomorrow morning through the evening. Winds will remain strong on the backside of the low as the system progresses east, though not as strong as with the warm frontal passage. Colder air aloft will keep the threat for rain snow showers over much of the bering through Wednesday. Long term forecast (days 3 through 7) The extended forecast begins Wednesday evening with the same longwave pattern in place. A cold upper trough sits over the bering sea with upper ridging to the east toward the panhandle. Between these two features lies a strong jet stream with a tropical connection, currently preciptable water is near 2.3 inches in the northwest pacific but will moderate as it moves east and north. As the associated front moves into the north gulf coast late Wednesday into Thursday, the surface pressure gradient will respond, making for potentially strong winds through portage valley turnagain arm and the upper elevations of the chugach. Warmer conditions will accompany the system as strong cross- barrier flow bring downslope conditions to the area. However, the strong moisture tap could lead to some rain making it through the dry low-levels. Strong winds will remain a threat through Thursday. Heading into the long-term, a sub-tropical system pushes up into the gulf, returning warmer temperatures and rain to much of the area on Friday. Into the weekend and beyond... Guidance really struggles with the evolution of these sub-tropical waves phasing into the longwave trough. Individual systems are not timed well or agreed upon in the surface pressure fields. Uncertainty remains high, but the active and warmer pattern will continue. Afc watches warnings advisories Public... High wind warning 181 185 187 191. High wind watch 195.

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. |
