 Heavy Snow Now Likely for the Northern Counties!


Exclusive Inland Northwest Summary Issued: Tuesday * January 23, 2018 @ 5:35 AM  

(By Climatologist Bob Lutz)


Short-Term Weather Outlook
A much stronger and wetter storm will arrive today bringing with it a variety of weather conditions.  The precipitation will start as either wet snow or rain around and south of the I-90 corridor, and wet snow in the northern counties this afternoon.  As evening arrives, there will likely be a switchover to snow again in most locations, and that snow may be heavy at times tonight, especially in the northern zones.  Milder air will slowly move northward during the overnight hours as well; however, there is still quite a bit of model uncertainty as to how fast that milder air will arrive.  Obviously, a slower arrival would mean higher snow totals while a faster arrival would result in less snowfall.  For Wednesday, I suspect that the milder air will overtake many locations leading to a mixed bag of wet snow and rain, changing to all rain by afternoon from south to north.  Then by Wednesday night, we'll see any lingering rain changing back over to snow again as cooler air moves in on the backside of the storm.          

Extended Forecast

A series of fronts will keep temperatures on a roller-coaster ride, and the weather quite stormy at times throughout much of the extended period!  These fluctuating temperatures will continue to give us a wide variety of precipitation types as well.  In the wake of the midweek storm, temperatures will trend a bit cooler and with minor disturbances moving through, snow showers can be expected both Thursday and Friday.  A more significant winter-like storm will be arriving during the early portion of upcoming weekend, followed by another slug of milder air going into early next week.                       
Exclusive Snow Plower's Forecast

Today's system will bring the next best chance of measurable wet snow with the highest totals north of a line from Deer Park to Athol.  Most locations will see snow to start under a slightly cooler air mass, but the snow will change to rain from south to north as milder air moves in with the storm late tonight or early Weds morning, making for a sloppy mess!  The far northern counties will be slower to see the changeover to rain which will likely result in higher snowfall totals.  As has been the case most of this winter, forecasted snowfall totals are highly dependent on the timing of the milder air arrival. 
Potential Snowfall Totals:  Valid through Weds * Jan 24 , 2018
Spokane Basin - I-90 Corridor:   1-4"
