And the NWS right now has a chance of rain/snow mix Monday evening and Tuesday morning with a chance of just snow showers late Monday/early Tuesday, which would correlate with what the models show.<br /><br />I think it will all depend on exactly how the cold air and the brief showers behind the front will coincide. As you mentioned in your previous post with this setup there won't be very much moisture behind the front, but if the cold air (helped by NW or WNW flow) can move into the valleys and lowlands before all the moisture is gone then I think it is reasonable to expect maybe a little accumulation even at the lowest elevations.<br /><br />It is definitely not ideal, but I think its possible. My concern would be that things end up slightly different. Since we are now into March the air could stay too warm, the trough may not push as deep (mainly a concern for the Portland forecast I would think), etc.Anonymoushttps://www.blogger.com/profile/14468734038469683964noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-74081098829074412522012-03-04T13:16:40.975-08:002012-03-04T13:16:40.975-08:00What happened to all the great weather we were sup...What happened to all the great weather we were supposed to get today?Scotthttps://www.blogger.com/profile/01041902355794062651noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-71867113959449515622012-03-04T11:29:05.358-08:002012-03-04T11:29:05.358-08:00I wish you guys luck.

It looks chilly.<br /><br />But what about a sneaky convergence zone? Strong NW flow could set something more diagonal further S. I'll live vicariously thru Seattles weather tomorrow. Dry, cold, and wind at my locale.smokejumperhttps://www.blogger.com/profile/05358322512081660205noreply@blogger.com
