Hampton Roads has been dealing with the rain since last Friday night, so I know a lot of folks are tired of the rain. We saw widespread rain this morning during the commute. A thunderstorm developed over Virginia Beach for a short period of time. We usually do not get thunderstorms with temperatures in the 40s, but this storm system is very dynamic. Plus it has cold air in the mid to upper levels of the atmosphere. Many locations have already picked up 0.5″-0.75″ of an inch of rain so far and we are not done just yet!
The band of rain over Richmond and Raleigh now will continue to push northeast and impact most of the region over the next few hours. So if you are seeing breaks in the rain now, don’t expect that to last. As this last round of rain moves in this afternoon, colder air will be moving in from the north. There is a slight chance we could see the rain changeover to a sleet/snow mix across the Northern Neck, Middle Peninsula and Eastern Shore (mainly Accomack County).
The changeover will be brief and could happen anytime between 12-4 PM. Here is the latest thinking.
Little to no accumulation expected across the Middle Peninsula and the Eastern Shore. The ground will be wet from all of the rain this morning, plus temperatures should be above freezing. A winter weather advisory is in effect for Northumberland County across the Northern Neck. This is the only area in our viewing area that could see the snow accumulate on grassy areas and decks. Keep in mind that this could change if the cold air doesn’t move in fast enough. Typically we see the colder air move in after the precipitation ends, which is one of the reasons why there is snow to our north and not here.
Snow totals will go up the farther north you go. Winter Storm Warnings are in effect for northern Virginia, Maryland, northern Delaware and Philadelphia. These areas could pick up an additional 3-6 inches of snow on top of what they got on Sunday.
Speaking of snow, check out this map of the U.S. It shows which parts of the nation have snow on the ground. About 2/3 of the country is snow covered as of today! Places in Texas still have snow from this past weekend’s storm. That is impressive.
Rain will come to an end before the evening commute. Cold night ahead as temperatures drop into the upper 20s. Any standing water may freeze overnight, so there may be some slick spots Wednesday morning.
Chance for a snow/sleet mix north is looking less likely this afternoon. Drier air is moving in and temperatures are still in the upper 30s. Can’t rule out a snowflake or sleet pellet, but that is about it.
