Spring weather is going into the cold case file. Hard to believe we just missed a record high from 1998. Mild temperatures of 70-degrees from Wednesday will be gone until next year. A monster winter storm with arctic air in tow will bring snow, sleet, and ice...tonight through Friday evening.
Today's rain will slowly change to sleet and freezing rain tonight…and then change to all snow on Friday. Snow accumulation of 3 to 6 inches by Friday evening.
When constructing a winter mix forecast, I like to monitor aviation forecasts and models...to see what pilots are dealing with. You can see...what a mess. Any drizzle or rain which is encountered at temperatures of freezing or below is likely to generate significant ice accretion in a very short period of time.
Snow in itself does not present an icing threat, since the water is already frozen. However, snow can be mixed with rain...water, which can contribute to the accumulation of hazardous frozen deposits. No...it will not be the ice storm of 2009 but ice accumulation at the surface is a threat.
Models indicating rain, freezing rain, sleet and snow.
At 10:00 p.m. rain will be changing to freezing rain and sleet.
Overnight through 7:00 a.m. on Friday...snow starts northwest of Interstate 64. If temps sink into the upper 20s...freezing rain and ice accumulation could be a hazard for commuters. Hopefully, temps will stay near freezing so we can get over to snow after some sleet.
At 2:00 p.m. snow starts to ramp up and move through the area. Most of the snow should end early in the evening. However, 3 to 6 inches of accumulation with isolated higher amouts.
