EUGENE, Ore. -- With the luck of the Irish, we have another day of sunshine and mild temperatures in the middle to upper 50s. Clouds will begin to increase from west to east this afternoon/evening as an upper-level low develops over southeastern Oregon allowing for onshore flow and marine clouds to push inland overnight. Overnight clouds will keep temperatures in the upper 30s and lower 40s.
Saint Patrick’s Day: Morning sunshine followed by increasing clouds during afternoon. Highs in middle to upper 50s.
Wednesday: Patchy morning fog and drizzle, followed by decreasing clouds and party sunny. PM snow showers in Cascades above 4,000 feet. Highs in middle to upper 50s.
First Day of Spring: Patchy fog, mostly sunny. Highs near 60.
Friday: Patchy fog, partly sunny. Highs near 60.
Saturday: Patchy fog, partly sunny. Highs near 60.
Sunday: Mostly cloudy w/ showers late. Snow level 5,000 feet. Highs near 60.
Monday: Mostly cloudy w/ showers. Snow level 3,500 feet, rising to 4,500 feet. Highs in low 50s.
Additionally, onshore flow could trigger some light drizzle late Tuesday into early Wednesday morning. Clouds will slowly decrease Wednesday afternoon as high pressure builds into the region. Despite drying conditions, light rain and snow showers will likely spark up during the afternoon over the passes.
Sunshine and highs near 60 degrees will return on Thursday for the first day of spring. Side note, this is the earliest start of spring in more than 100 years due to leap years. Spring normally starts on either March 20 or March 21. Spring 2020 will officially start at 8:49 p.m.
On Friday a large, low-pressure system will settle off the coast of northern California and will persist through Sunday. Yesterday, models were inconsistent of whether this system will remain offshore or run the coastline. The trend is for it remain offshore, keeping us dry and mild through the weekend.
Models are in good consensus that our next weather maker will drop southward out of Canada Sunday night into Monday, bringing cooler temperatures and the chance of valley rains and mountain snow. The exact timing and details are still being worked out, but we could use the moisture. The current snowpack is 71 to 86% of normal thanks to last weekend’s storm.
