Rollercoaster weather continues in the region with a projected high of 40 Tuesday followed by a drop to 15 degrees overnight with snow showers and about an inch of snow, depending on where the line breaks between a little of the white stuff and a lot.

Weather guru Kevin Myatt of The Roanoke Times, the weather prognosticator we trust to predict what may or may not happen with unpredictable Mother Nature, reports:

The difficulty with snow forecasts for Tuesday night and Wednesday is that there will be two different waves of it, neither of which are overly compelling for our backyard, but neither of which can be entirely dismissed, given that even a small amount of snow could cause big issues on the roadways.

Wednesday could be our last day of a high below freezing for the next couple of weeks. Forecasts call for a high of just 21 degrees Wednesday with snow tapering off and sunshine in the afternoon.

Thursday’s forecast calls for a high of 39 and a lot of 22 with sun and no precipitation, 49 degrees on Friday and 52 on Saturday with sun and improving conditions.

Sunday’s forecast predicts a high of 57, followed by 50 degrees on Monday with rain, then sunny on Tuesday, rain showers on Wednesday, then cloudy Thursday and rain and snow showers on Friday of next week.

If forecasts hold, the final full week of January could bring rain and snow showers with highs in the 40s and overnight lows in the mid 20s.

All of this, of course, is subject to change in what has become the winter of temperature extremes and varying forecasts by the National Weather Service.
