Weather 4-9-19


We are starting out our weather day with a trof of low pressure overhead containing a cold conditionally unstable air mass. Mostly cloudy skies this morning in the Wenatchee Valley with sunny skies expected by this afternoon. We will also see windy conditions out of the northwest this afternoon as high pressure butting up against low pressure will kick up 15-25 mph winds with gusts up to 30 mph, highs in the upper 50’s. The shortwave ridging is short-lived however as it gets replaced with a northwest flow more cluttered with moisture and small scale disturbances running through it which allows for a reintroduction of showery weather conditions.

For Wednesday, expect increasing clouds with a 20% chance of scattered showers, windy with highs in the upper 50’s.

By Thursday, a progressive, wet and unsettled weather pattern will be over the region with once again, a 20% chance of scattered showers with afternoon highs in the upper 50’s. This weather pattern will repeat a couple more times as high pressure rebuilds into the region during the day Friday bringing mostly skies to our area and warmer temperatures with highs in the lower to mid-60’s.

The ridge will be short lived as another Pacific disturbance moves into the region Saturday afternoon. This will keep the weather cool and showery the remainder of the weekend with valley rain and mountain snow. Expect mostly cloudy skies on Saturday, a 40% chance of showers with highs near 60 degrees.

Sunday we will see partly to mostly cloudy skies, a 30% of scattered showers with afternoon high temperatures in the upper 50’s. We should see somewhat of a break from the wet weather Sunday night and early Monday before yet another wave will move into the region Monday night and Tuesday for more showers. Temperatures will be in the upper 50’s to lower 60s with a 40% chance of showers each day.
