EUGENE, Ore. -- The cold upper-level low that has been overhead over the last few days will slowly move southeast across the Pacific Northwest and out of the region tonight. It will trigger showers, some small hail, lower snow levels, and the chance of an isolated thunderstorm. That said, showers will not be as widespread as Tuesday, more sun breaks are expected on Wednesday.
Wednesday: Partly sunny w/ isolated showers. Snow level 2,000 feet. Highs near 50.
Thursday: Morning fog, partly sunny. Highs near 50.
Friday: Rain likely. Snow level 2,500 feet, rising to 4,000 feet. Highs in the low 50s.
Saturday: Showers. Snow level 3,500 feet. Highs in the middle 50s.
Sunday: Mostly cloudy w/ showers. Snow level 4,000 feet. Highs in the middle 50s.
Monday: Rain likely. Snow level 4,000 feet. Highs in the upper 50s and low 60s
Tuesday: Mostly cloudy w/ showers. Snow level 3,500 feet, rising to 5,000 feet. Highs in the upper 50s and low 60s
Fog will develop Wednesday night in the interior valleys into Thursday morning. The combination of radiation cooling dropping temperatures to the dew point, light winds, and lingering surface moisture will trigger fog for most of the area. That fog will give way to partly sunny skies.
The next system will arrive on Thursday night into Friday, but the with bulk the energy remaining offshore, rainfall is not expected to be particularly heavy.
Models continue to show several waves of energy moving through the Pacific Northwest over the weekend. There will be plenty of moisture for these systems to tap into as tropical moisture from the central Pacific spills in through Saturday. This will keep rain chances elevated through the weekend.
Another low pressure system will drop into the region on Monday and Tuesday, continuing rain chances into early next week. Models also suggest drier, milder weather returning for the middle of next week.
This wet pattern will help put a dent into our overall dry March. The rainfall deficit for the month it sitting between -1.42 inches in Roseburg to as much as -4.17 inches at the coast in North Bend. The snowpack is also down, with Willamette Basin at 85% of normal and the Rogue/Umpqua Basin at 70% of normal.
