The Meteorological Service is issuing a winter storm watch due to heavy snow in County Clark

After days of uncertainty, forecasters have done everything they can to forecast winter weather at the end of the week, with forecasts of up to 6 inches of snow and possible frosty rain expected.

The National Meteorological Service’s Portland office issued winter storm surveillance from Thursday afternoon to Friday morning, forecasting heavy snowfall with 1-6 inches of accumulation and occasional light frosty or tinny rains west and south of the subway area.

“Plan snowy roads,” he said to the storm.

The storm also predicts that the wind will explode at up to 45 mph, with the strongest wind pointing east of the interstate 205 in the gorge of the Columbia River.

Precipitation is expected to decline later on Thursday night, but cold temperatures in the 1920s and east winds cause low wind chills throughout the region.

It is expected to rain before 10 a.m. Thursday morning, which will become a mixture of rain and snow by 1 p.m., and then after 13 p.m., total snow as snow levels fall from 2,000 feet to 200 feet.

Snow is expected to be expected on Friday, snow is expected on Saturday, and the snow will turn back on Sunday and then turn to rain on Sunday evening.
