Warming weather is expected to develop this week across much of the Inland Northwest while a weak area of low pressure moves through tonight and tomorrow bringing a chance for showers. The atmosphere today will likely be a little more stable than yesterday and as a result we expect to see little of any chance of thunderstorms. Expect partly to mostly cloudy skies in our Monday forecast with a 20% chance of isolated showers with high temperatures this afternoon near 70 degrees.
By tonight, the aforementioned upper level low over Western Oregon is expected to slide into Central Oregon during the night and into Tuesday morning increasing our chance for showers as wrap-around moisture moves into Northcentral Washington from the south/southeast. The Wenatchee Valley can expect a 50% chance of showers tonight and a 50% chance of showers on Tuesday with highs tomorrow into the lower 70’s.
Wednesday and Thursday will both be quiet weather days and much warmer with partly cloudy skies, light winds and afternoon high temperatures in the upper 70’s to near 80 degrees.
On Friday, weak low pressure slides through bringing a 20% chance of showers with high temperatures in the mid to upper 70’s.
When looking at the upcoming weather weekend, it is still too early to see the progression of a low into the Pacific Northwest and its associated precipitation. Temperatures look like they will slightly warm each day, with highs above normal in the upper 70’s and lower 80’s and lows in the upper 40s to mid 50s.
