FORECAST ANALYSIS AND DISCUSSION
Tonight through Wednesday.
A decaying wave, with an associated occluded low located over the Bering Sea, is continue to fill and move towards the southeast into the Gulf of Alaska by later this evening. This will continue to weaken, while another area of low pressure ejects up into the north of the Chukchi Sea. Additionally, there are still some of the displaced energy within the deformation zone of the low well off to the southeast over Juneau's area, which has provided some on and off snow for portions of the eastern mainland, mainly along the Alcan border, from Northway to Eagle. This snow will continue to taper off going into tomorrow as the major shortwave progresses further eastward and away from the region. An area of high pressure building over the Beaufort Sea is going to allow for much colder air advection from the north and establish across the region. This will allow for much of the Interior, Brooks Range, and Arctic Plains, to experience sub-zero temperatures beginning tomorrow, and then further dropping off throughout the week. An overall drier pattern will occur as this also allows for further clearing of skies to aid in temperatures dropping even further.

Coastal Hazard Potential Days 1 and 2...Elevated water levels above the normal high tide line possible across the West Coast, highest around the YK Delta around 1-3 feet, are expected through tomorrow.
A Special Weather Statement has been issued for the YK Delta to highlight this.

.EXTENDED FORECAST DAYS 4-7...Wednesday through next Saturday night.
By Wednesday, most of the region will be dominated by high pressure conditions, with mostly clear skies and much colder temperatures.
Ensembles have continued to reveal increasing PWAT values going into the latter part of the week and through the weekend as the region may be influenced more by a stronger area of low pressure moving into the Bering Sea, which may help to draw up more moisture ahead of it over the YK Delta and allow for a better chance of snow for some portions of the West Coast and western Interior, while most of the remaining CWA remains colder and drier.

Coastal Hazard Potential Days 3 and 4...None
