More showers and scattered afternoon thunderstorms will occur around Northcentral Washington today and tomorrow. Low pressure churning off the coast of Washington will move little today and tonight sending shortwaves of moisture our direction. Expect partly to mostly cloudy skies today with a 20% chance of isolated showers or t-storms, along with a west breeze, afternoon high temperatures today in the upper 60’s to near 70 degrees.

Our rain chances will further increase Thursday as our area of low pressure off- shore kicks inland. With a bit more upper level support and cooler temperatures aloft, thunderstorms Thursday afternoon and evening may be capable of pea hail and wind gusts to 35 mph. Both today and Thursday, we will have to keep a close eye on the radar. Downpours could be problematic for flood prone spots like urban areas or burn scars that have lost their snowpack. The Wenatchee Valley and Columbia Basin will see cloudy skies tomorrow with a 70% chance of showers and thunderstorms with cooler afternoon highs down into the mid 60’s.

Friday will be an in-between storms day with mostly sunny skies, dry weather with afternoon highs in the lower 70’s.

After a brief lull, the weather turns wetter late Saturday as the next storm system moves in. Northcentral Washington can expect mostly skies Saturday with increasing clouds late in the day with afternoon high temperatures near 70 degrees. By Saturday night, the large trough of low pressure moves our way bringing a 70% chance of overnight rain showers.

On Sunday, precipitation becomes likely all across the Inland Northwest with a cold front/upper trough moving inland where some locations could pick up between .75”-1.00” of moisture, highs near 70 degrees. This system will also be accompanied by increased instability and a threat of thunderstorms in the afternoon.

Our weather picture will remain active Sunday night into Monday with a 50% chance of showers and thunderstorms with afternoon highs in the upper 60’s to near 70.

By Tuesday, the upper level area of low pressure will move away leaving behind mostly sunny skies and warmer temperatures with afternoon highs in the lower 70’s.
