FORECAST ANALYSIS AND DISCUSSION
For Tuesday through Friday.
At the start of the forecast period Tuesday a shortwave low around 521 decameters pulls cold air from the north against the Brooks Range and weak ridging shifts from the eastern Bering Sea into the Gulf of Alaska. A low in the Bering Sea stalls west of the ridge and is prevented from riding over the top of the ridge by a strong 545 decameter upper level high in northeastern Siberia. This low, while stuck, is still able to send a front up the coast late Tuesday which itself stalls against the colder, Arctic airmass Wednesday. This stalled front brings periods of light snow and some rain to the West Coast, Western Interior, and portions of the Central and Eastern Interior through Thursday.
Snow will be the most prevalent p-type, but periods of rain are possible in the warmer valleys during the afternoons and evenings.

Thursday into Friday the next low in our pattern approaches the Bering Sea. This low forces an area of weak high pressure to move east as well, which in turn forces the stalled Bering Sea low east into mainland Alaska. The low loses its organization and pushes into the West Coast and Interior creating more widespread, although still light, rain and snow showers late Thursday into Friday. All the while colder air continues to sit over the North Slope keeping that region cold and then Interior and Coast cool.

.EXTENDED FORECAST DAYS 4-7...
For late Friday through next Tuesday.
At the start of the extended forecast period late Friday showery conditions continue across the Interior as another, much stronger, low enters the western Bering Sea. Around this same time a strong upper level low moves south from near the north pole towards the North Slope further reinforcing the cold air in that region. The stronger low in the Bering Sea and the large region of Arctic air will push against each other in unpredictable ways. There is currently a large amount of uncertainty with the position and strength of this low and even less certainty for how it interacts.
This uncertainty means that there is extremely low confidence for the exact impacts from the Bering Sea low as it tries to approach the West Coast.

Additional precipitation is most likely from the Seward Peninsula south, but a more northerly track could bring additional snow and rain deep into the Interior. Winds will generally be north to northeasterly, but the speed will depend on exactly how strong and close the low gets. We will continue to monitor this storm through the end of the week.

Coastal Hazard Potential Days 3 and 4...None
