EUGENE, Ore. -- Friday morning we are tracking a weak frontal system that is bringing clouds and some spotty showers to the region.
These showers will be light and will not result in significant rainfall. Clouds will stick with us throughout much of the day Friday, but we could see some sunbreaks starting Friday evening as high pressure builds into the region.
Friday: Mostly cloudy w/ spotty shower. Highs in low 70s
Saturday: Mostly sunny. Highs in low to mid 70s
Sunday: Showers and thunderstorms. Highs in upper 60s
First Day of Fall: Mostly sunny w/ am fog. Highs in upper 60s
Tuesday: Mostly sunny. Highs in low 70s
Wednesday: Mostly sunny. Highs in low 70s
Thursday: Mostly sunny w/ slight chance of showers. Highs in low 70s
Higher pressure will decrease any shower chances Friday night; however, valley fog will be around Saturday morning as ground moisture remains above seasonable highs from recent rainfall. The fog will lift Saturday in the late morning, giving way to sunshine and allowing temperatures to rise into the mid-70s.
Higher clouds will build from the north and west on Saturday night ahead of a cold front that will bring rain and possible thunderstorms to the region on Sunday. Rain will spread onshore before dawn on Sunday, and will move inland throughout the day. Rainfall will be modest compared to the last two storms we had this past week. This is because the majority of the energy from the jet stream will be behind the front, instead of ahead of it, like we saw this past week. Still, postal-frontal showers will likely be strong and could produce some thunder and lightning.
Northerly winds will increase Sunday night as high pressure builds into the region. This will result in some clearing overnight, which will allow for temperatures to fall into the 40s in the inland valleys. This will likely be the coolest night we have seen this season. Additionally, fog will be likely seen on Monday morning. Once the fog clears, there will be plenty of sunshine Monday afternoon with highs near 70.
Additional frontal systems may bring more wet weather later in the week, as well as some cooler temperatures. How much rainfall we will see is still up in the air and we won’t likely get a better idea until after the weekend.
