Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 525 PM EDT Sat Jul 04 2020 Valid 12Z Wed Jul 08 2020 - 12Z Sun Jul 12 2020 ...Overview and Guidance/Predictability Assessment... Upper troughing will focus toward western/southwestern Alaska by the end of next week via the northwest and southwest. A cold front associated with the lead upper low near the Bering Strait on Wednesday will push through Southcentral and into the Gulf. Another system from the central North Pacific will eventually move toward Kodiak next weekend. A consensus blend served well to start the forecast, but then the 12Z ECMWF was preferred over the other guidance for Fri-Sun with the handling of the western system. The GFS seemed too quick overall with the pattern, though the trend was a bit quicker from 24 hrs ago out of the central North Pacific. ...Weather/Hazard Highlights... Troughing will promote generally cooler than average temperatures over most of the state next week into the weekend, perhaps by 10-15 degrees over the Brooks Range. Parts of the western coastal areas may see near to above average temperatures. Showers will be favored over the Alaska Range amid daytime heating and cooling mid-level temperatures. Showers and perhaps steadier rain are possible over the western Aleutians Wed-Fri as a dying warm front approaches from the south and a cold front approaches from the north. Showers may be enhanced over Southcentral as the upper trough and a weak surface low pass by the region. Rainfall is not expected to be heavy over a widespread area, but could be locally heavy.
