Another quick update this evening as little has changed from last evening. Temps warm up into Thursday when heavy rain of 1-3″ arrives. Temps then slowly slide back towards freezing through the weekend before possibly warming back up for more rain early next week.
Here’s a quick glance at the upper level setup Thursday afternoon. Notice the negatively tilted trough digging to our west with strong S/SE flow ahead of it. This storm will be tapping moisture directly from the tropics. A secondary disturbance is forecast to drop into the trough over the weekend forming an ocean low that could bring snow to the area (especially eastern areas) by Saturday into Sunday.
I just wanted to go over Thursday a little more as it looks to be a fairly dreary storm. It starts as snow for inland areas Wednesday night but will quickly go over to heavy rain by early Thursday morning. Heavy rain is likely through Thursday evening and 1-3″ is expected with the higher amounts over the SE facing terrain where a little upslope boost is expected. Winds will pick up as well as heavy showers tap into strong winds aloft. Gusts to 40 mph are likely.
Here’s the upcoming week at a glance. No signs of a sustained spring until likely the last week of April. Despite that, cold like we’ve had the last few days is likely banished to the north until fall.
