Following the Arctic front`s quick passage and weather event late yesterday afternoon, there will be some remaining breezy winds in areas such as the Columbia Basin, Okanogan Valley, Purcell Trench, and Eastern Cascades. However, these breezy conditions will be slowly calming throughout the day.
Today will mark the beginning of a dry and calm weather trend ahead as an upper level ridge establishes itself in the Northwest. Temperatures will remain much colder than seasonal norms with today`s high temperatures under sunny skies the coolest of the week with most readings in the 30s to near 40 for high temperatures and tonight`s lows dropping into the single digits and upper teens throughout the Inland Northwest.
However, tomorrow begins the week`s slow warming trend, Wenatchee Valley weather calling for sunny skies with afternoon highs in the upper 30’s to near 40 degrees. Partly cloudy skies expected for Thursday with calm wind and afternoon high temperatures in the mid 40’s. Stagnant air conditions will be the main focus for the end of the week.
Thursday, Friday and Saturday look to be the days for our strongest inversions due to the cold nights. It`s likely that we will see pollutants build up near the surface through the night and into the morning hours with little mixing and relief in the afternoon.
For Friday and right through the upcoming weekend and into Monday, expect mostly sunny skies each day with afternoon high temperatures in the lower 50’s Friday, mid 50’s Saturday and into the upper 50’s for highs on Sunday and Monday which will be above normal for this time of year.
