In the early overnight hours, the rain will begin to switch over to frozen precipitation. We will start to see a mixture of sleet and frozen precipitation enter the vicinity around 4 am. Surface temperatures hover right above the freezing mark. By 6 am a sleet and snow mixture will make its way into our region. It is expected that we could see up to 1/2 of an inch of frozen precipitation by 7am.

The next major precipitation switch over will occur around 8 am Thursday morning. Starting around 10 am, we will see the sleet mixture switch over to all snow along with surface temperatures dropping below 32 degrees Fahrenheit. Within this period, it is forecasted that we could potentially receive 1-2 inches of snow by 10 am.

By 1pm all falling precipitation will now be in the form of snow. Temperatures will have drop to the mid-high 20's. Take a look at the graphic to the left. As you can see there will be some stronger snow bands that will dump higher snowfall totals over those areas. Depending on the location of these bands, at this time there could be between 3-5 inches of snow on the ground.

Although Winter Storm Thor begins to move off to the east, snow bands continue to engulf the northern and central regions of Virginia. During this time, Thor will have dropped between a total of 5-7 inches of snow around our region. The surface temperatures will be in the lower 20's.

By 7 pm precipitation will flip over to all rain, however temperatures remain in the lower 20's. Snowfall totals at this time will be around 6-7 inches.
I hope this helps when deciding when to travel, or perhaps leaving for spring break. Stay safe and use good judgement when traveling during inclement weather! Stay with ForecastGMU for Winter Storm Thor updates!
