Area forecast discussion, Mar 21, 5:56 AM AKDT, 9 hours 21 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 556 AM AKDT Sat Mar 21 2020 .ANALYSIS AND UPPER LEVELS... The upper level weather pattern consists of ridging over the western Bering, a trough over the eastern Bering from the Pribilofs north and east, so the Pribilofs are at the base of the trough. A northwest to southeast oriented 115 kt jet streak extends north and west of the Pribilofs. A ridge is over Southcentral. The ridge axis is along the Alaska/Yukon border. A second southwest to northeast oriented 130 kt jet streak lies from Unimak Island to Denali. Snow is ongoing across nearly all of Southwest Alaska this morning, with rain falling from King Salmon south. With full cloud cover in place across all of Southern Alaska, temperatures are largely homogeneous as well, nearly everywhere away from the coast in the 25 to 32 degree range. From King Salmon south, temperatures are between 35 and 40, with any precipitation remaining all rain. && .MODEL DISCUSSION... The models are in very good agreement on the synoptic scale through this weekend's forecast, including timing and precipitation amounts. The main forecast challenge will be temperatures and precipitation type. With temperatures hovering right around freezing, even a degree or two will be the difference between rain and snow and accumulating snow. Thus, while forecast confidence is high regarding that there will be widespread precipitation today, there is low confidence on the precipitation type, snowfall accumulations, and temperatures. && .AVIATION... PANC...VFR conditions will become MVFR early this morning as snow begins, then IFR for the late morning and early afternoon hours. By late afternoon the snow will diminish from west to east, resulting in VFR conditions returning. VFR conditions will persist through Sunday and into the early workweek. Light winds are expected during the snow, which will become northerly with occasional gusts will develop tonight. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... A front is moving through Southcentral Alaska today bringing a mix of precipitation types to the region. Figuring out where the rain-snow line will be is the biggest challenge to the forecast package. Snow should be the rule from Kenai northward but high temperatures in the mid to upper 30s will help keep accumulations lower due to a much lower snow ratios and compaction of the heavy wet snow. In the city of Homer it should get warm enough to mix with rain or turn to all rain. However the Homer Bluff and East End Road are more likely to see all snow. Considered a Winter Weather Advisory for snow for those areas, but decided to keep amounts less than the 6 inches necessary for the advisory due to the amount of compaction of the snow. The Copper River Basin is also interesting as southeast winds should downslope out the precipitation for most of the morning near Glennallen. However, these winds should diminish in the afternoon which will allow temperatures to drop again (they could approach 40 degrees in the southeast winds). That will bring a period of snow to the area, but not nearly as much as there would have been without the winds. This front will move through rather quickly, allowing northerly outflow winds to develop again tomorrow allowing skies to begin to clear again over the region. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)... (Today through Sunday evening) The main focus in the short term is the snow currently moving through the region. It has already ended near the Kuskokwim coast. Further south, the snow extends further back into Bristol Bay, as this region has better jet support aloft leading to increased ascent and higher precipitation intensities. While both areas will gradually see the snow end from west to east as we head through the day, earlier thinking of 1 to 2 inches (maybe 3) for the Kuskokwim Valley (lower and upper) and a more general 2 to 4 inches for Bristol Bay eastwards towards Iliamna seems on track. A brief burst of cold advection will follow the precipitation shield, with clearing skies in its wake. This will lead to substantially colder temperatures observed by this time Sunday morning. Given the clearing skies and fresh snowfall, some patchy fog may also develop. Temperatures will begin their rebound on Sunday as warm advection aloft begins to move back into the region. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)... (Today through Sunday evening) High pressure currently over the western Bering and Aleutians will rapidly build eastward through the day, reaching the Alaska Peninsula by this evening. This will allow for only scattered cloud cover in most locations, with perhaps some patchy fog developing, especially across the western half of the region as warm advection aloft commences. Otherwise, look for dry conditions to prevail until Sunday afternoon/evening, when an approaching front brings a return to wet weather for the western and west central Aleutians. && .MARINE (Days 3 through 5)... No gales are expected in the Gulf in days 3 through 5. Gales are possible on Thursday across the Western Aleutians with the approach of a low. Elsewhere across the Bering, no gales or high seas are expected. && .LONG TERM FORECAST (Days 3 through 7)... There remains strong confidence that a strong upper level ridge will be in place over the southern half of the state early next week. An upper level low is expected to move north towards the central Aleutians from the North Pacific weakening as it does so. This upper level low will eventually force the ridge to weaken and move southward by midweek, opening up a zonal flow pattern aloft. By the end of the week, models continue to suggest a strong low will approach the Bering from the west with a track just west of the Aleutian Chain. There still remains uncertainty with the exact placement of the low but models continue to show better agreement on this feature leading to moderate confidence in the forecast. Further east across Southcentral and Southwest Alaska, models are in disagreement on what the upper level pattern may look like across the mainland. Some guidance shows an upper level trough diving southward while other guidance shows an upper level ridge leading to a tough temperature forecast. Also of note, each model differs on the strength of this upper level trough leading to low confidence in the long term. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...NONE.
