Area forecast discussion, Feb 18, 4:52 PM AKST, 10 hours 53 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 452 PM AKST Mon Feb 18 2019 .ANALYSIS AND UPPER LEVELS... A front associated with a weakening, vertically stacked low over Bristol Bay continues to rapidly push eastward towards the eastern Gulf and ALCAN border. An upper level trough over mainland Alaska is slowing moving eastward. Cold air wrapping around the backside of the low is causing some cumulus clouds over the Bering this afternoon. Southwest flow is moving into Bristol Bay and Southwest Alaska, as well as a few snow showers over the K-Delta. Light snow showers have also been observed across Southcentral, along with a mix of rain/snow along the coastal regions. One key weather feature to keep an eye on is quick moving low center developing in the North Pacific south of Adak. && .MODEL DISCUSSION (through Wednesday afternoon)... Numerical models are in very good synoptic agreement through Wednesday afternoon. All have similar handling of the outflow pattern across the North Gulf on Tuesday and the developing low and surface front moving into the eastern Bering Sea Wednesday. The GFS will be used overall in the western domain and the higher resolution NAMNEST in the east capture outflow winds. && .AVIATION... PANC... MVFR/IFR conditions possible in snow showers until after trough passage overnight. North winds should develop on Tuesday and bring drying and VFR conditions. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... (Mon night through Wed) The main items of interest in the short term are refreeze potential tonight as temperatures drop back into the upper teens to lower 20s for most locations across the Anchorage Bowl. Then, strong northerly winds will develop for Tuesday as an area of low pressure crosses southwest Alaska tonight and into the Gulf by morning, reaching the Yakutat area by Tuesday evening. As this occurs, a brief ridge of high pressure will build across Southcentral, with it being centered north of Broad Pass. This in turn helps promote a tight pressure gradient along the eastern slopes of the mountain ranges, with the winds increasing for the Prince William Sound region, Whittier, Thompson Pass/Keystone Canyon, and the Copper River Delta. For these locations look for peak wind gusts to top out in the 40 to 50 mph range. As such, we hoisted a Winter Weather Advisory for this section of the Richardson Highway for Tuesday morning through Wednesday morning. Visibilities could drop to a half mile or less in blowing/drifting snow through Thompson Pass. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3...Mon night through Thu)... Low pressure crossing over to the gulf tonight will bring snow along the Kuskokwim Valley and Bristol Bay areas east of Dillingham and then taper off toward Tuesday morning. A ridge builds across the Southwest in the wake of the front which supports fog development across the Alaska Peninsula and the Southwest as low level moisture is abundant and temperatures cool to dewpoint values overnight. The next front moves across the Alaska Peninsula Tuesday morning. Precipitation will likely start out as snow along the boundary, however the warm core system is expected to warm the column enough to change over to rain. The boundary pushes to the west coast during the afternoon, however the ridge just inland shunts its progression. Gusty southeasterly winds are expected to increase along the front with snow and blowing snow, especially further north, for Wednesday night. On Wednesday night into Thursday, a strong short wave develops along the base of the upper trough and swings north which brings another frontal push which is expected to bring widespread snow across the area. We will be monitoring this closely for potential advisory (6") level accumulations. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3...Mon night through Thu)... Low pressure keeps an unsettled pattern over the Bering through Thursday. While low pressure across the eastern waters exits tonight, another track north along the west Bering. The next North Pacific storm moves up to the Central Aleutians tonight and continues on a northward track. This system will bring rain and snow across the Aleutians tonight along with gusty easterly gales. The storm picks up northward momentum Tuesday morning which swings the front at a fast pace to the northern waters making blowing snow issues for Pribilof Islands fairly brief. The following system enters late Wednesday across the Western Bering...bringing blowing snow possibilities across the western Aleutian Chain as the cold core center passes close to Shemya. && .MARINE (Days 3 through 5...Thu through Sat)... A very active storm track continues across the Western Bering Thursday through Saturday. Models have come into agreement that a mid-960 mb low will move up the Western Bering on Thursday, bringing southerly gale force winds through most of the Bering Sea. Another low pressure system is expected to develop on its tail in the Northern Pacific, crossing the Aleutians and moving into the Bering on Friday afternoon. Winds with this next system are expected to remain near max gale force, but northwesterly winds on the western side of the system may increase to storms by Saturday. Of note in the Gulf of Alaska, high pressure will build in behind the low expected to move into Prince William Sound on Thursday. This has the potential to cause strong northwesterly outflow winds across the Western Gulf and through the Barren Islands Thursday afternoon. Right now winds are expected to peak below storm force but this bears watching as the two systems develop. && .LONG TERM FORECAST (Days 3 through 7...Thu through Mon)... The westerly storm track will continue across the mainland on Wednesday and Thursday before a ridge builds in over the eastern mainland on Friday. The ridge will shift the weekend's storms to a more south to north track through the Bering Sea. The storm that moves through the mainland on Weds and into the Prince William Sound on Thurs will bring snow across the region, with the potential for 6 inches or more through the Mat-Su Valley. By Friday, the ridge will be settling into place, which means that any weekend potential for precipitation will be kept from the Kuskokwim Mountains westward. Although there is certainty in the ridge building over the mainland through the weekend causing a change in the general storm track, some uncertainty still exists in the strength of the ridge. This could make the difference in whether some precipitation makes it further inland Saturday and Sunday, or whether it is mainly held to the coast. Regardless, it does look like an influx of warm air is likely, so precip type for the western mainland will likely be a forecast challenge as we move into early next week. && .AFC WATCHES/WARNINGS/ADVISORIES...
