During the early hours, light freezing rain is also likely in several areas of central Washington.
Weather patterns that are dryer will be in place throughout the weekend and into next week.
Even though precipitation possibilities are expected to return to certain places early next week, there will be no significant winter storm systems to worry about this year.
Temperatures are Dropping
Today through Saturday night: A well-defined low-pressure system off the coast of southern Washington and northern Oregon will march eastward this morning.
They are almost unanimous in their forecasts for today's low-pressure system, which will weaken as it tracks through Southwest Washington late this morning and then take a southeast turn as it goes towards Northeast Oregon late this afternoon.
Because of the weakening nature of the low and the southerly move in the track, the bulk of North Central, Eastern Washington, and North Idaho should remain dry for the time being.
Models predict that a band of light precipitation will pass across the Wenatchee and Moses Lake regions somewhere between mid-morning and late afternoon.
The possibility of freezing rain cannot be ruled out at temperatures around freezing, but with POP levels of about 20-30 percent, no adverse effects are envisaged.
Tonight, the low-pressure system will move out of the region, and an upper ridge will pass over the area.
There is significant agreement amongst models of stratus spreading over the area.
Models indicate this wet boundary layer extending through Saturday with continuous low clouds forecast as a flat higher ridge impacts the region.
Fluctuating Temperatures During the Day
It is expected that the temperature will fluctuate very little during the day, with lows mostly in the upper 20s to low 30s and highs generally in the mid-30s.
During the day on Saturday and into Saturday night, a weak wave is expected to pass over the ridge, bringing very light snow or flurries to parts of NE Washington and the Idaho Panhandle.
Dense Fog Advisory Canceled
There is no longer a Dense Fog Advisory in effect for sections of Northeast Washington and the North Idaho Panhandle, which was in effect until 5 a.m. today morning in those areas.
Since midnight, visibility has been steadily increasing, with webcams in various locations indicating improvement in a variety of locations.
