Meteorologist David Martin said it appears the storm will be fast-moving, but could drop several inches of snow, sleet and freezing rain between Monday night and Tuesday. Little or no snow and sleet accumulation expected.
The second storm is expected to arrive Friday night into Saturday and bring possible record-setting snowfall totals and icy conditions. The daytime high will be about 31 degrees.
In addition to the freezing rain, it will be windy on Saturday with NE winds at 10 to 20 and higher gusts.
There's quite a few deliveries that will be happening for Valentine's Day and the good news is that the snow will not pile up.
The entire area is game for a major ice event on Monday. High temperatures will struggle to reach the low 40s.
Freezing rain or sleet is most likely along the Coast Range, in the central Willamette Valley and in the southern portions of the metro area. Chance of precipitation is 30%.
This is when the combination of the storm track, moisture and cold air can work together to produce as much as 6 inches in the Seattle metro and an additional 4 inches in the Portland metro, which is about what those cities average in a year. The heaviest freezing rain is probably south and east of the Beltway. Easterly winds may gust as high as 40 to 50 miles per hour overnight, especially in the West Hills and eastern portions of the metro area.
Temperatures as low as minus 45 degrees Fahrenheit (minus 43 Celsius) gripped Montana and Minnesota as cities such as Bismarck, North Dakota, shivered at minus 26 F (minus 32 C).
Weather service models are not in full agreement how much of the precipitation will fall as rain, freezing rain or snow and in what locations. Benavides said anywhere between 1-1.5 inches of snow may be seen in San Marcos on Monday morning. Forecasters aren't expecting much more than an inch or 2 across interior MA, with mainly an inch or less predicted elsewhere.
A daily assessment of the potential for at least 1 inch of snow in the next week, on a 0-10 scale.
A chance of snow and freezing rain is possible until 8 a.m. Sunday, forecasters said.
