Weather 10-20-20


LOWLAND SNOW POSSIBLE FRIDAY NIGHT INTO SATURDAY MORNING FOLLOWED BY UNSEASONABLY COLD TEMPERATURES THIS WEEKEND. The Inland Northwest will experience a relatively quiet weather day today with a mix of sun and clouds and near average temperatures with afternoon around 60 degrees.

On Wednesday, Northcentral Washington can expect mostly sunny skies, northwest winds 5-15 mph with high temperatures in the upper 50’s. Also, by tomorrow afternoon, north winds will channel down the Okanogan Valley, the Waterville Plateau, and the Columbia Basin with sustained winds of 15 to 20 mph with gusts up to 30 mph as chilly Canadian air spills into the region.

Look for another relatively quiet weather day on Thursday, but it will be quite a bit cooler with increasing clouds throughout the day and afternoon high temperatures in the upper 40’s to lower 50’s.

On Friday, expect big weather changes coming to the Inland northwest. Weather models are continuing to track a potentially significant late October winter storm. National Blend of Models has increased precipitation chances across much of the Inland Northwest for Friday into Friday night. Model solutions are coming into better agreement with the timing of the low-pressure system and trough from the north with the bulk of the precipitation coming Friday afternoon into Friday evening. Cold Canadian air is already going to be in place from the cold front passage on Wednesday, so the set up will be favorable for mostly snow as the dominant precipitation type.

Wenatchee Valley weather for Friday calling for a 70% chance of rain mixed with snow and MUCH cooler with afternoon high temperatures only around 40 degrees.

Some snow could linger into Saturday morning with partly cloudy skies by afternoon with highs in the upper 30’s to lower 40’s. That surge of cold air will make it feel quite brisk on Saturday.

The weather model consensus is for high pressure ridging to build in on Sunday as the large storm system moves away. This will result in a drier period with a gradual warming trend for late next week. However, before we do warm up. it`s possible that we will see some record low temperatures for both Sunday and Monday mornings.

Weather forecast for Sunday and Monday will be sunny and unseasonably cold with afternoon high temperatures only around 40 on Sunday and the lower 40’s on Tuesday.
