December 16th, 2012 at 9:13 pm by under Weather

December of 2012 has not only been warmer than normal, it has also been drier than normal too. As of Saturday, Dec, 15, the Norfolk Airport recorded 0.14 inches of rain for the month so far.

Dec 2012 – Drier than Normal

3.26 inches is the normal value for the ENTIRE month of December. This number is just a 30-year average of all the rain recorded each December. December 2012 has been much drier than normal, up until today. Many locations have already picked up 1/2 inch of rain throughout the day. 24-hour rainfall totals are pictured below.

I captured these graphics around 8:30 PM and the rain is still falling across much of Hampton Roads. Expect these numbers to continue to go up by tomorrow morning.

A very powerful storm system will be impacting Virginia and North Carolina Monday afternoon and Monday evening. A few showers and some patchy fog will be around tomorrow morning around 7am. You may want to give yourself a little bit of extra time to get to work Monday morning.

I think most of the region will get a break from the rain around midday. However, another round of showers and maybe even a few thunderstorms will move in Monday afternoon/Monday evening. All of this activity will develop out ahead of a cold front.

Future Trak Model – 5PM

With a warm front well to the north and a cold front to the west, Hampton Roads is going to be located in the warm sector. The warm sector is typically the most unstable, this is the area where we watch for developing thunderstorms. We will have plenty of warm and moist air to work with which is usually hard to come by in December. Instability should be limited due to the cloud cover and the rain Monday morning. But, we will have lots of wind shear (when winds change direction and/or speed with height inĀ  the atmosphere). These winds could support a few thunderstorms tomorrow afternoon/evening.

The cold front will move through Hampton Roads early Tuesday morning and dry us out. The weather pattern will remain very active this upcoming week. A stronger cold front will move in by the end of the week bringing us another chance for rain and a big cool down by next weekend.
