Mild pattern remains, rain and snow arrive Wednesday
The mild weekend has given us a taste of spring but as often is the case this time of year, wide swings in the weather are expected. This will be the weather patterns this week as rain and snow arrive on Wednesday morning. The precipitation will mainly be rain from about mid-morning on, but may start out as a mix of rain and snow. We are going to be watching out for some icy conditions early in the day as well, but currently it is not in the forecast package.
A Winter Weather Advisory has been issued by the NWS starting Wednesday afternoon and lasts until Thursday night. Issued for the mountains, but lower elevations will see periods of rain and snow along with some icy roads.
The rain will be steady most of the day Wednesday and the mountains will be in line for more snow, albeit wet snow. The rainy and wintry mix conditions will be off and on through the rest of the week and I expect to see some patchy ice on Thursday morning.
Thursday will see an end to the widespread rain and mountain snow, but not before a transition to snow overnight from Wednesday. There may be some sunshine from time to time Thursday but the overall wet pattern is not going to change until next week.
Friday will see another day of snow and rain changing to rain as temperatures will be in the upper 40s, but start out in the middle 20s. Icy mornings will be a concern most of the week.
Saturday continues the theme of rain and snow over the high desert with temperatures dipping slightly below freezing to start the day, then warming to the 40s by noon. Sunday may be the day with the most precipitation, and the concern for flooding is now on the table as the snow and rain start to become a bit overwhelming for the small streams and creeks.
The temperatures over the Cascades seem to indicate that the snow is not going to be melting significantly this week, so the flooding concerns are mainly due to the persistence of the rain at lower elevations.
