Saturday Midnight Quick Post

11:45pm Saturday

The forecast from Thursday night still looks good!  Temperatures still have a ways to go before we can even think about sticking snow at the lower elevations.  11pm numbers:

Check the previous post for more detail, but here’s a fresh summary:

SUNDAY 6AM-10AM

– Snow showers in hills, could be a TRACE to 2″ anywhere at/above 1,000′  SOME SNOWY ROADS POSSIBLE UP THERE

– Snow showers in lowlands, but a few degrees above freezing.  So it will either be no sticking or a “barkdust/grass/cartop” sticking in spots.   WET ROADS

SUNDAY 10AM-6PM

– Light snow showers continue, lots of sunbreaks too.  In fact it may be just partly cloudy the entire 2nd half of the day for many of us.

– NEAR/ABOVE 1,000′  Some light accumulation at times since temps remain closer to freezing up there.  Slushy or wet roads by early afternoon up there

– LOWER ELEVATIONS  Wet or dry roads, snow in the air at times…we top out in the lower 40s

SUNDAY EVENING AFTER 6 PM

– Light snow showers may continue and then eventually end.  IF WE’RE GOING TO GET WIDESPREAD STICKING SNOW IN THE LOWLANDS THIS WILL BE THE TIME.  

TOTAL SNOW BY THE TIME IT DRIES OUT SUNDAY NIGHT?

  • NOTHING TO 1/2″ MOST LIKELY FOR THE LOWEST ELEVATIONS IN WESTERN OREGON. 
  • TRACE-1″ more likely Kalama to Longview (slightly “wetter” up there)
  • 1-3″ possible near/above 1,000′

 

MONDAY AM

– Dry skies, frozen ground/streets.  If no snow actually falls in lowlands Sunday evening/night, then it’ll just be scattered icy spots for AM commute.

REST OF MONDAY  Roads dry out, chilly and mainly sunny.

Models are converging on a possible 2nd snow event Tuesday night.  More on that tomorrow!  But the unusually cold weather plus more than one chance for lowland snow this upcoming week scared me enough to reschedule my vacation.  I’ll be taking a week off in spring instead of this coming week.  Seems more appropriate don’t you think?
