Rain pattern expected Thursday through Sunday

Bend, Ore (KTVZ) – A complex weather pattern is developing across the Pacific Northwest as two low pressure systems will impact the region. The end result will be scattered showers Thursday and Friday with more widespread rain over the weekend.

Thursday will be a transition day with some spotty showers developing from and area of low pressure to our south and west. The low will stay off the coast until it begins to deteriorate Friday and dissipate before getting onshore in Northern California. This feature will spread rain north into Oregon, but we should only see scattered or spotty showers. There is a low but not zero chance that we may hear the rumble of thunder across the region, but few and far between.

After this low, we will call it low number one, dissipates the remaining moisture will continue to linger over the region. The rain chances increase slightly Friday and the chance for some thunderstorms becomes a bit more likely. Still a low chance, but not zero. Keep the rain gear handy.

Saturday is when the second low arrives from the Gulf of Alaska and cools us down and churns up the rain again. Expect temperature readings in the upper 50s as the rain cools the region. The threat of thunderstorm is likely to diminish in the cooler air mass, but a rogue strike is not impossible  The mountains will see a mix of rain and snow as the snow level is still will above 5500 feet.

Sunday will also be rainy and chilly as highs will top out in the low 50s. Chilly rain is the best way to define the day as we continue to deal with cloudy and wet weather. The snow level will drop slightly, but not enough for the high desert to see any frozen precipitation. Mountains may get a few inches of snow, but the mountain passes will be below the snow level.

Monday morning should start out with mostly cloudy skies, but lingering rain is possible. Sunriver, La Pine and Sisters may be the only locations that will see a wintry mix before sunrise, so if you are traveling in those areas, stay alert for slick roads.

Late Monday and through the middle of the week Central Oregon will stay dry. Highs return to the upper 50s and low 60s most of the week.

Here is what it looked like this morning at Mount Bachelor.
