Ridging of high pressure building in over the Inland Northwest will produce sunny skies and seasonably warm temperatures for all of Northcentral Washington. Many areas could see their last 80-degree day of the year come Saturday. Big weather pattern changes coming our way late in the day Sunday as a large area of low pressure moves down from the north bringing clouds, cooler temperatures and a good chance for rain that could continue through next week.

Northcentral Washington weather today will be sunny and warmer with afternoon high temperatures in the upper 70’s to near 80 degrees.

The ridge of high pressure moves well to the east Sunday night and as such, rain will begin to spread west to east Sunday into Monday. However, Sunday’s weather for the most part will still be nice with increasing clouds and highs in the upper 70’s. By Sunday night, we can expect a 50% chance of rain as the weather system moves in.

Monday looks to be a wet one with cloudy skies and a 60% chance of rain during the day and evening with afternoon high temperatures in the lower 70’s.

For Tuesday, the conditionally unstable airmass will move east allowing for a transition toward more showery conditions that linger on a bit into Tuesday morning. There is a 40% chance of morning showers Tuesday and much cooler temperatures with highs in the mid-60’s.

Increasing clouds in the forecast for Wednesday with a 40% chance of evening showers, high temperatures in the mid 60’s.

Yet another large area of low pressure moves our way Thursday bringing a 50% chance of rain with highs in the upper 60’s.
