Spring Temps Today; A Soaker Monday/Tuesday

March 12, 2017

10pm Sunday…

That forecast from last Thursday was pretty good.  Friday and Sunday turned out just spectacular with dry weather, abundant sunshine and the first lower 60s in the metro area so far this spring.  Here are the numbers today…

By the way, today was the first day in a month that we stayed completely dry.  Not even a trace of rain for the first time since February 13th.  Of course there have been several days with a trace.  Take a look at the number of dry days each of the past few months of March:

The average number of days we would expect to see dry weather is 13.  Remember 2013 & 2015?  Just a few wet days here and there otherwise plenty of dry weather to kick off spring.

Tomorrow through Wednesday morning we’ll have a stationary front sitting overhead since we’ll be boxed in between a warm upper-level ridge to the east and a cold trough to the west.  A mild southwesterly jet will be parked overhead as well.  This means two solid days of gloomy skies and abundant rain.  The cold front comes through Wednesday and at that point we’ll transition to scattered showers.  The main story:  Monday & Tuesday will be “indoor days” as we say.  With such a warm flow of air the snow level will be way up around 9,000’…think April or early May with this airmass, so at least down here in the lowlands it’ll be a “warm” rain.  How much rain?

I think 1.50-2.50″ is a good number for the next 3 days in the western lowlands of Oregon and SW Washington.  More is likely in the mountains.  Some spots in the Coast Range and west slopes of the Cascades could see 6-8″.  That’s pretty heavy for March; it’s rare to see any sort of flooding this month.

Looking farther ahead, it appears the next chance for a dry day is Thursday, and maybe Sunday/Monday next week.

To help you relax, check out this really neat pic of clouds over Yachats Saturday morning.  Ken Gagne posted this pic of “Undulatus asperatus” on our Facebook page.  The best part is that the pic shows waves not only in the ocean but waves in the sky too.  Nice photobomb by a seagull too.
