A thermal low pressure trough over the Alaska Range will move north

lower 60s with RH falling to 20-30 percent along this feature today.



A strong low in the Southern Bering Sea will move to the southeast 

Bering Sea tonight, into Bristol Bay on Sat and into the Gulf of 

Alaska on Sun. This will cause southerly Chinook winds develop

then decrease Sat night.  This will bringing dry, windy and warm

conditions to the Tanana Valley this evening through Sat night.
