This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.

The high pressure ridge that has been over the area is slowly weakening.   Today through Wednesday the north state will be mostly sunny with a few mid and high clouds.  Winds will be light.

The change in the weather pattern is beginning.   The high pressure ridge that has been over the west is weakening as low pressure trough develops in the Gulf of Alaska.  Today we have mostly sunny skies with temperatures slightly above normal.   Thursday the first low pressure trough and frontal system will be approaching the coast.  Clouds will increase during the day with light rain over the north coast and northern mountains by evening.  

Friday all of the north state will see light to moderate rain as the trough moves through.  Snow levels will start out high but will drop to 4000 to 5000 feet by late Friday.  Gusty south winds will precede the storm.  Saturday the trough will be moving east and the precipitation will turn to showers and by late morning will be confined to the higher elevations with the valley partly to mostly sunny.

Sunday another low pressure trough will move through (see map below).  This system will bring light rain to our area with snow levels 3500 feet north and 5000 feet south.  

Monday will be partly cloudy with showers over the mountains.   A stronger wetter storm system will move into the area late Tuesday and Wednesday.
