Weather 7-1-19


Our weather for today is showing an upper level area of low-pressure that remains positioned within close proximity of the Washington coast. The counterclockwise rotation around the low results in a flow of somewhat warm, moist, and unstable air into Eastern Washington and North Idaho. The Wenatchee Valley can expect increasing clouds throughout the day, west winds 10-20 mph and gusty with a 40% chance of showers by tonight, highs in the mid to upper 80’s.

For Tuesday and Tuesday night, weather model suggest a cold front drops down from the north and pushes the bobbling area of low pressure off the coast a bit to the south. The resulting convergence between the cold front moving southward and disturbances moving northward on the east side of the low, coupled with the moisture and instability should provide an atmosphere conducive to convection in the form of thunderstorms. Most of Northcentral Washington will see at least a 20-30% chance of thunderstorms tomorrow with cooler high temperatures down into the lower 80’s. There is some risk of flash flooding, especially on and near recent burn scars of the East Slopes of the North Cascades and Okanogan Highlands.

As the area of low pressure loses strength and moves away, we will still see some residual clouds on Wednesday with northwest wind 5-15 mph, afternoon highs will be in the lower 80’s.

For our Independence Day on Thursday, a warming trend begins as an upper level area of high pressure begins to dominate our weather with mostly sunny skies and afternoon high temperatures in the mid 80’s. The weather forecast for the fireworks show in Wenatchee Thursday night is calling for partly cloudy skies, light wind with temperatures around 9:00 p.m. in the lower to mid-70’s.

Our temperatures will warm  up even more on Friday, Saturday and Sunday with mostly sunny skies expected each day and afternoon high temperatures in the mid to upper 80’s.
