Alaska Extended Forecast Discussion NWS Weather Prediction Center College Park MD 717 PM EDT Thu Jun 02 2022 Valid 12Z Mon Jun 06 2022 - 12Z Fri Jun 10 2022 ...Overview and Weather and Hazard Highlights.. A mean trough will be in place over the Gulf of Alaska/North Pacific through the extended period. In this flow, a lead/lingering closed low and effects will slowly weaken well offshore over the southern/southeastern Gulf of Alaska which will provide focus for some convection for the Interior. Scattered convection is expected to develop across the Southwest and South-central Mainland, waffling eastward toward East/Southeast Alaska and back through the course of this forecast. Some periodic chance for light to locally moderate precipitation over the Panhandle as a series of easterly waves ride underneath the mean ridge. Temperatures will moderate and trend warmer with time. ...Guidance/Predictability Assessment... For days the models have struggled with small-scale variances that within the synoptic pattern beyond the day 4/5 period, particularly with the location of the two trough near the North Slope and Arctic region. Additionally, it has maintained the idea of a mean trough with multiple lows cycling though and slowing near the eastern Gulf of Alaska. The stance has been starting off with a general model blend and then transitioning to mostly means by middle and all means by the end of the extended period and that was the approach taken once again given not much has changed since the last cycle.
