Thunderstorms through the Weekend

Meteorologist Melissa Frey’s Forecast Discussion:

The area of low pressure that was over Northern California is slowly making its way north. This storm is independent from the jet stream which means it has nothing to force it to move east. It will slowly move north over the weekend, eventually moving out into the pacific near the Columbia River Monday.  This means the thundershower threat will continue through the weekend.

We saw cloud cover and some light rain across western Oregon Friday morning from thunderstorms that developed across the Cascades Thursday night. These storm are pretty much wrapped up, but another round will fire up this afternoon.

Storms will begin around lunch time in the Cascades moving into Oregon in the late afternoon and into the valley late tonight. These storms are expected to bring not only lightning, but heavy rain to the east slopes of the Cascades. The National Weather Service has issued a Flash Flood Watch for the East Slopes of the Cascades, including Bend, La Pine and Sunriver. The Watch goes into effect at 11 a.m. Friday and continues through Sunday evening. Flooding is especially  likely in the areas of recent wildfires.

The best chances for seeing rain and potential lightning in the valley will be Friday night from 11 p.m. to 8 a.m. Saturday and again Saturday night and Sunday night.

Saturday will likely start with clouds and light rain, clear mid day, with thunderstorms developing in the evening. We’ll see this pattern, repeat on Sunday as well.

By Monday, we should be in the clear, returning to mostly sunny skies and highs in the low to mid 80s.

Have a great weekend!
