The upper level ridge of high pressure that’s brought us the beautiful warm, sunny weather will hang around for one more day with partly cloudy skies today and high temperatures near 60 degrees. Below this ridge is an upper level low that is pinching off from a larger weather system out in the Pacific. That low will bring us a 30% chance of light rain showers by tonight with less than a tenth of an inch of moisture expected.

The last feature in these first few days of the forecast is the next upper wave that will move across the region Saturday night. Northcentral Washington can expect partly cloudy skies for Saturday and cooler with highs dropping down into the mid-50’s. We will see partly cloudy skies on Sunday and a brief break from the wet weather with afternoon high temperatures in the mid-50’s.

Low pressure residing off the Washington Coast will send a series of shortwave storm systems into the Pacific Northwest bringing several rounds of showers our way next week and a transition toward cooler, near normal temperatures. Expect cloudy skies on Monday with a 30% chance of rain during the day with highs only in the lower 50’s. Monday night, a wetter weather system moves into Northcentral Washington with a 90% chance of rain with a quarter of an inch of precipitation possible. Snow levels Monday night will drop to 3000 feet. Tuesday will be a mostly sunny day with highs in the mid-50’s. On both Wednesday and Thursday next week, another weak storm system moves in bringing with it a 30% chance of rain both days and afternoon high temperatures in the low to mid-50’s. The air mass however looks to remain seasonably cool keeping additional contributions of snow- melt and flooding possibilities in check.
