Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 437 PM AKDT Tue Jul 2 2024

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: This afternoon through Friday)...

For the rest of today and Wednesday, an upper-level low and attendant surface low will continue to linger near the western Gulf/North Pacific while a weak ridge of high pressure spans across Southcentral. A couple very weak waves are setting off areas of rain showers across the northeastern half of the Copper Basin today, which should mostly dissipate by this evening.

Despite the developing high pressure, low level flow will remain south to southwesterly (especially near the Cook Inlet), and this will tamp down highs in the low to mid 60s for much of the region this afternoon even with partial sun returning. Much of the same is expected for Wednesday as the narrow ridge remains mostly intact and the Gulf low moves even farther out into the Pacific.

On Thursday (July 4th), hints of a bigger pattern change will begin to be felt by some. A series of shortwaves interacting with a band of moisture streaming around the ridge from the Bering Sea into the Interior will begin to encroach from the north, with a stronger trough expected to approach the Alaska Range by the afternoon. The main change from the previous forecast package is that the onset of rain could happen earlier for areas farther south, such as the Anchorage and Matanuska Valley areas. There is greater likelihood for rain to being in the evening, however it is possible for it to start earlier in the afternoon. The greatest confidence remains or the northern Susitna Valley and northern Copper River Basin, where the greatest amounts of rain can be expected.

By Friday, a transient upper-level ridge tracks across Southcentral and brings a brief respite in rain for most of the region before an upper trough approaches from the west on Saturday.

.SHORT TERM FORECAST SOUTHWEST ALASKA, BERING SEA/ALEUTIANS (Days 1 through 3)...

A front extending off a Kamchatka low moves into the central Bering Sea this afternoon, bringing widespread rain showers to Central Aleutians. High pressure ridging over Southwest Alaska brings in some patchy fog and/or low ceilings to the Southwest coast and Alaska Peninsula. Shortwaves riding overtop the ridge will drop south into Southwest Alaska by Thursday morning. This will initiate a rainy pattern which first arrives at the Kuskokwim Delta then advances eastward across Southwest by Thursday afternoon.

.LONG TERM FORECAST (Days 4 through 7)...

The long range models are in more agreement today with the pattern change mentioned in previous discussions. The areas of high pressure that have been persistent over the Bering Sea and the Gulf of Alaska in the early part of the period will start to break down allowing a North Pacific low to track northward into the Gulf. This combined with troughs of low pressure transiting across the Bering Sea and Kuskokwim Delta will track eastward across the region through the end of the period. As a result, expect scattered precipitation and cooler temperatures across the much of the forecast area. Additionally, gusty winds and possible small craft conditions are expected in Cook Inlet and coastal regions of the Kenai Peninsula Saturday afternoon and into Sunday.
