Showers at times for Tuesday

Looking at a few models here.... our showery weather will continue into tomorrow, but should be to a lesser extent. Current inferred satellite image still shows plenty of showery cumulus streaming toward us, however showers should be more confined to the Olympics/Cascades with the lowlands seeing more in the way of sun breaks tomorrow. And as mentioned, the showers should be even more scattered as our cool/cold 500mb trough moves out of our region.(see 50mb chart for Tue afternoon) Also should be a bit warmer, perhaps lower 50`s as temps near the surface rise a few degrees above freezing and also rising thicknesses/heights. But could still see few showers during the afternoon due to daytime heating.

Moving onward to mid-week. I have been asked if I see another 'wind storm' for the Wed/Thurs period. Right now the answer is no. However, it does still appear that a strong cold front will be sliding through on near westerly flow aloft for LATE Wed into during the day Thursday and may not move out of Western Wa till about Friday. So on tonights models, surface and 850mb winds seem fairly light.

Alas, it appears the GEM/MRF/EURO/GFS models all show some sort of deep trough coming through for the upcoming weekend for more cool and unsettled conditions.
