Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 507 AM AKDT Fri Sep 15 2023 .ANALYSIS AND UPPER LEVELS... The overall pattern continues to be mostly dictated by a large, complex upper low that just does not want to budge from its current location over the far northern Bering Sea. A number of shortwaves embedded in cyclonic flow in place across much of the outlook area are continuing to rotate mostly east on the south side of the broad upper low. Most notably, a pair of stronger troughs are now passing near and to the south of the AKPen and Kodiak Island. An attendant surface low is now approaching the west side of Kodiak Island as it deepens, producing areas of light rain across the AKPen and much of Kodiak Island, as well as winds up to small craft range in the western Gulf. Southerly and onshore flow continues to stream into Southcentral out ahead of the approaching Gulf low. Southcentral is now seeing a break in between systems and a resulting lack in upper level forcing over the region. Thus, rainfall is now limited to areas where upslope enhancement is favored in this regime, including most of the north Gulf Coast and Prince William Sound. Out in the west, strong zonal flow continues to push over the southern Bering Sea as a 160 kt upper jet streak moves near the crest of a flat, transient ridge centered over the Aleutian Chain. Farther upstream and even farther west, the next more potent low is just starting to come into the picture, with the center now moving quickly eastwards a ways off to the south of the western Aleutians. && .MODEL DISCUSSION... Model agreement is beginning to improve for the pair of strong lows expected to eventually merge into one distinct center later this weekend over the Gulf. However, there are still some slight timing discrepancies for both systems at this juncture. For the first low expected to move over the Gulf through Saturday, the ECMWF and Canadian models have generally depicted the low rapidly weakening and arcing northeast towards the Kenai Peninsula and Prince William Sound faster than the NAM and especially the GFS through Saturday afternoon. There is a similar split for the low skirting right along the Aleutians and AKPen today and tonight, with the GFS and NAM taking the low east slightly faster and farther to the south than the Canadian and ECMWF models. This spread persists as the low enters the Gulf and merges with the remnants of the first system through Saturday night. Overall, confidence is improving for the active low track persisting into the weekend, but there are still some details to iron out. && .AVIATION... PANC...Periods of rain will continue as a series of short-waves transit the region. Persistent low level southeasterly flow should be enough to maintain VFR conditions through the TAF period. The low level flow will begin to weaken and back toward the northeast Saturday morning as the weakening low pushes onshore along the north Gulf coast. This may allow ceilings to lower to MVFR sometime Saturday morning, with steady rain developing. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Today through Sunday night)... Key messages: *Wet weather will continue across the region through Saturday, with some areas drying out on Sunday. *A storm will strengthen over the Gulf today through tonight, then be replaced by a larger and stronger storm Saturday through Sunday. This will bring gale to storm force winds to much of the Gulf waters along with building seas. A couple of out of phase short-wave troughs digging southeastward from the Alaska Peninsula into the southern Gulf of Alaska and northeast Pacific will lead to development and strengthening of a surface low in the southern Gulf today. Ridging out ahead of this system will aid in creating a strong frontal boundary across the northern to eastern Gulf waters, with gale to storm force winds expected this afternoon through tonight. This system will lift northward toward Southcentral Saturday morning as a deepening low tracking eastward along the Aleutian chain moves into the Gulf. This second system will be more potent and impacts more widespread. While the low center will head quickly for the eastern Gulf, a high amplitude ridge upstream in the Bering Sea combined with cold air advection and unstable air behind the Gulf low will lead to strong northwesterly winds across the western to central Gulf (and Kodiak Island) Saturday night through Sunday. Rain will be continuous along the coast and Kodiak Island through Saturday. Interior areas of Southcentral will see some occasional breaks in the rain. While multiple inches of rain will fall along the coast (and certainly in the mountains), rain rates do not look heavy enough to pose a big threat for flooding. As the low heads for Southeast Alaska on Sunday, rain will diminish across Southcentral. Persistent cloud cover and rain will maintain cool temperatures along with a narrow range between daytime highs and nighttime lows. && .SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3: Today through Monday morning)... The status-quo of the active and progressive pattern looks to continue through the short-term period. A broad trough stretching from Siberia to southwest Alaska will maintain its position. This configuration will keep most of mainland southwest in a showery regime through at least Saturday before a shortwave ridge works in for Sunday. This could bring a little reprieve from precipitation before showers return Monday for coastal locations and the Alaska Peninsula (AKPEN). Further out west, the parade of low pressure systems will continue for the Bering Sea/Aleutian Chain. This first system arrives this morning for the western Chain and tracks in close proximity to the Chain to the southern AKPEN while deepening/strengthening. This system is expected to bring widespread sustained gale-force winds along the North Pacific side of the Aleutians, with pockets of storm-force winds along its track. The other story with this system is the moderate to heavy rain. Albeit a relatively quick moving system, 1.5 to 2 inches of rain are expected from the western to central Aleutians this morning through Saturday morning. Lesser amounts closer to an inch of rain are expected along the southern AKPEN. As the system exits to the Gulf Saturday afternoon, a ridge builds in behind for much of the Chain on Saturday, yielding a brief break from the rain and strong winds. The next systems enter both the western Bering Sea with a separate one tracking in close proximity to the Aleutian Chain on the North Pacific side on Sunday. Both of these systems do not look quite as strong as the system slated for today. Nonetheless, rain looks likely, along with at least small-craft winds, across the Bering and Aleutians for Sunday into Monday. && .LONG TERM FORECAST (Days 4 through 7: Monday through Thursday)... The latest long term forecast has a low moving through the Gulf of Alaska and a second low moving into the Bering on Monday. Surprise! Unsettled conditions with continued rain chances look to continue for the foreseeable future. Yesterday there was mention of Invest 93W, currently located in the West Pacific. Models have struggled with whether this low will be picked up by an earlier trough or get missed initially and lifted into the Aleutians over the weekend. We will lean with the latter scenario and Monday's Gulf low should possess a fair amount of moisture associated with it. Thus, the Gulf will remain quite showery with potential for heavy rain lifting into eastern portions of Prince William Sound and Southeast Alaska. Additionally, a threat for high winds may develop within barrier jet flow from Yakutat to Icy Bay as the low finally moves into the eastern Bering. To the west, the low moving through the Bering on Monday is expected to be much broader in size, but also less intense, as it moves across the Aleutian Chain through the middle of next week. Showery conditions will plague both the Aleutians and the Bering through Wednesday. The same low expands into Southcentral Wednesday into Thursday. Thus, precipitation chances, initially low for Southwest, will increase significantly by late Tuesday through Wednesday. Southcentral may see a brief break from precipitation on Tuesday before precipitation becomes more substantial and widespread across Southcentral Tuesday night into Wednesday. && SYNOPSIS AND MODEL DISCUSSION...AS SOUTHCENTRAL ALASKA...SB SOUTHWEST ALASKA/BERING SEA/ALEUTIANS...DN LONG TERM...BL
