The low-pressure weather system that has been sitting near Portland the last day or so will weaken a bit and move inland across Central Washington this afternoon. This is the same weather system that brought flash flooding to the greater Wenatchee area yesterday. South Wenatchee rain gauges measured 6-tenths of an inch of moisture with higher totals in the mountains. This will bring another round of showers and thunderstorms to parts of Northcentral Washington today as well but on a much lesser scale. Expect increasing clouds today with a 30% chance of showers and thunderstorms with afternoon high temperatures in the mid 70’s. The two main areas of weather concern for later in the day are the Cascades east into the Waterville Plateau and Okanogan Valley and Highlands. The showers will begin to pop up before noon in the Cascades and as the day progresses the showers and developing thunderstorm threat will move into the Plateau and Okanogan areas. The main threat with these storms will be brief heavy rain and lightning.
On Saturday, another weak weather system will form just off the Washington/Oregon coast bringing partly cloudy skies and a 20% chance of very scattered afternoon showers, highs in the upper 70’s.
The weather Sunday and Monday should be mainly dry with mostly sunny skies Sunday with afternoon highs in the mid 80’s while a few more clouds roll in on Monday with warm afternoon high temperatures once again into the upper 80’s.
On Tuesday, expect mostly sunny skies, light winds and highs in the mid 80’s.
The weather forecast for the 3rd and 4th of July look pretty decent for outdoor activities. Temperatures look warm enough to spend time at the lake but not too hot for a game of golf, a hike, or barbecue. At this time, it looks like mostly sunny skies each day with highs in the 80s for the majority of the Inland Northwest.
