It has been over two-years since Reagan National Airport has picked up over two-inches of snow. A strong storm may change that.

An area of high pressure will briefly build overhead as temperatures fall into the 20s to lower 30s. Although highs will still be below average for this time of year on Monday, sunshine should make for a pretty nice day, or as some would say: "the calm before the storm."

Now for the exciting and challenging part of the forecast. By know, you have probably heard some chatter about the potential for a significant mid-Atlantic storm. Clouds will start to increase Tuesday. Rain, possibly mixed with snow will develop by evening overspreading the region from southwest to northeast. Depending on temperature and elevation, rain will mix and change over to snow late Tuesday night and extending into Wednesday. Chances are better for heavier snow west of Interstate 95, but accumulating snow is also likely east of Interstate 95. In other words, within a relatively small geographical area, expect a wide spread in terms of final snow totals.

The storm will jet out to sea by Wednesday night. Whatever snow actually sticks won't last long, a strong March sun angle will help with the melting process.

Spring can't be far away, Daylight Saving Time begins next weekend.
