Sunday, March 7th, 4:00 A.M.
A line of moderate rain showers is developing along a cold front early this A.M., moving eastward over the I-5 corridor as I write this discussion (around 4:00 A.M.). Steady rain will continue to move eastward this morning, leaving partly cloudy skies and scattered showers over northwest Oregon and southwest Washington. There will be some decent dry time this morning in between a few showers, but expect daytime heating to help fuel more shower activity this afternoon. If we get enough surface heating, some of the showers will turn heavier, and could even develop into isolated thunderstorms. In most cases, we’ll just see more intense showers with some small hail. Don’t be surprised though if you hear a rumble of thunder from the northern Willamette Valley to interior southwest Washington. High temps will end up in the low to mid 50s. Showers will dwindle this evening and tonight.
It looks like our Monday morning commute will be a dry one, but don’t expect the whole day to be dry. Showers are likely to move in from the south during the afternoon, and will drift north into the metro area and southwest Washington by the evening. A few leftover showers will also be possible Tuesday before conditions dry out. Expect highs to range between the low to mid 50s both Monday and Tuesday.
Beyond Tuesday, computer models are in agreement that high pressure will dry conditions out and bring us a bit of a warming trend. Highs will climb into the mid to upper 50s Wednesday and Thursday, and should be in the low to mid 60s by Friday. Our next chance for rain could arrive by Saturday.
Have a great Sunday!
