The snow that showed up on Sunday is going to get some additional inches according to the National Weather Service, coming up Thursday and even heavier Friday evening into Saturday.

The local supply of de-icer was quickly depleted in every store in the area and the snow and ice mean Metro will be on snow routes. Ride sharing services will be limited as will grocery delivery from Amazon and others as delivery slots are quickly filling up.

Bring sensitive flowers into shelter, make sure pipes in crawl spaces are insulated and be prepared for some indoor time. The 40 degree high on Thursday will give you a chance to get the things you need.

Here's the Wednesday forecast from the National Weather Service:

SHORT TERM /TODAY THROUGH SATURDAY/...A cold and dry pattern will remain in place today and Thursday.

Skies are generally clear this morning, other than a few locations with low fog - mostly in sheltered river valleys and over Lake Washington.

The clear skies definitely helped a overnight temperatures drop down into the teens at many locations with a few spots dipping down into the single digits. Sunny skies today, with below normal temperatures - albeit a bit warmer than yesterday - reaching into the mid to upper 30s. Expect cold overnight temps again tonight with low 20s and even a few spots dipping down into the teens again. The upper level ridge axis will shift to the southeast Thursday resulting in another dry day with temperatures a bit warmer - in the low 40s - possibly the warmest day of the week.

A cold storm system sliding south along British Columbia late Thursday night into Friday morning will bring the threat of another - potentially significant - winter storm to the area. Models remain in good agreement regarding the overall pattern with precipitation moving from the north Friday morning, drop southward across the area during the day. Temperatures through the northern third of the interior continue to look cold enough for precipitation to fall as snow. The remainder of the interior - especially south of Snohomish county may see more of a mix of precipitation types initially with flow remaining southerly into Friday evening before outflow from the Fraser works fully through the interior lowlands.

This should occur by Saturday as the low drops south off the Oregon coast and temperatures cool. Models differ on the amounts of precipitation associated with this system, and there continues to be a fair amount of uncertainty associated with the myriad details that can affect the amounts and locations of lowland snow in this kind of pattern. One thing to watch will be the potential for easterly flow developing which could help moderate temperatures east of the I-5 corridor mitigating snow fall.

This kind of pattern would conversely enhance snowfall through the hood canal area. With the colder temperatures Saturday, precipitation is expected to fall as snow with some models showing a deformation zone forming somewhere over the central Puget Sound. This feature could result in an area of enhanced snowfall. Perhaps just as significant as the potential for lowland snow is this system will bring another round of strong NE outflow winds from the Fraser River Valley late Friday night into Saturday.

The strongest winds are expected over the north interior with breezy conditions expected elsewhere. Things being to wind down Saturday night into early Sunday with precipitation ending from north to south. This system will potential result in widespread impacts from snow- covered roads, cold temperatures, and strong outflow winds up north. Please continue to monitor the forecast for the latest information. .

LONG TERM /SUNDAY THROUGH TUESDAY/...from previous discussion...Ridging attempts to briefly build in Sunday into early Monday in wake of departing system. A few snow showers could linger through Sunday morning before everywhere temporarily dries out. Depending on fresh snow cover, temperatures may struggle to reach the freezing mark Sunday afternoon with another chilly night into Monday morning. Cold, progressive pattern continues Monday into Tuesday as another system digs south from BC. Currently, this looks much weaker than Friday-Saturday system but model differences remain. Regardless, could see another round of lowland snow with compounding impacts from this week. But far too early to speculate on details. Let`s get through this Friday-Saturday system first.
