FORECAST ANALYSIS AND DISCUSSION
Weak ridging over the area ends today as several upper level lows converge over Alaska and the Bering Sea creating a very broad trough of low pressure aloft. A strong Arctic high moves from the eastern Siberian Coast north and east into the high Arctic. These two features will create the stronger east and northeast winds that we'll be seeing during the latter half of the week. Model confidence is good on the overall pattern, but has moderate confidence in the smaller details. No particularly hazardous weather is anticipated however.

.EXTENDED FORECAST DAYS 4-7...
The broad troughing shifts further west into the Bering Sea as ridging attempts to reestablish itself over the Alaskan mainland early next week. This will bring slightly warmer temperatures to the Interior Sunday and Monday before the ridge breaks down again with additional rain showers next Tuesday.

Coastal Hazard Potential Days 3 and 4...None
