I didn’t know whether to cry or laugh looking at the models tonight. We have a very wet 3 days on the way, especially Thursday and Friday. Just when we get a totally dry day, hopes rise and we make plans to get some yardwork done or something planted in the garden. Then our La Nina Spring slams us upside the head with another soaking. Yuck…I think my fruit trees at home and native broadleaf trees are about 3 weeks behind normal right now.
The image above is from our 00z RPM model, showing the 72 hour precipitation forecast. Note the precipitation falls as mainly snow in the Cascades…maybe 15-20 inches at the higher resorts by Saturday morning.
There does appear to be a break in the steady rainfall beginning this weekend. Upper level heights rise (slightly), and no significant systems move through our area. This would be more typical April weather rain-wise. However the upper level flow is still from the northwest, so a cool airmass remains. More frost in the outlying areas is definitely possible Sunday-Monday.
