Showers for the weekend

Good afternoon to all.

Seeing the latest models here, it still appears a cold front will slide through here during the morning hours of tomorrow with scattered showers and a cooler air mass following behind it for the upcoming weekend. And as you can see, the cold front with associated area of low pressure is still aways off shore. That area of low pressure per the OPC(Oceanic Prediction center) shows the low to eventually weaken over next several days near the GOA while our cold front continues to swing through our region.

This cool showery air mass should also bring snow levels back down with more snow in the mountains as this trough looks to be over us for later part of the weekend. I wont say much, but WRF12z is showing a LITTLE spotty lowland snow for early hours of Monday morning. This also looks to be when another possible trough brushes us for the Mon/Tue period with continued cool conditions. In the slightly longer range, it appears the MRF/EURO/GEM model shows us briefly getting into light zonal flow with main zonal energy being just to our north. So rain and showers will continue to be in our forecast for at least first half of next week if not longer.

  1. Hey Andy. After looking at the extended gfs, it shows several inches of snow falling over southwest washington and the hood canal by Tuesday morning. How likely is this? Thanks.
