Today's Weather Disscusion





Very quiet today except for in the Mid-Atlantic and Southeast, where a cut off low is producing a lot of rain and some severe weather in North Carolina and Virginia. There is plenty of heat and humidity and CAPE, and there is actually a moderate amount of wind shear. This is allowing a lot of strong storms to develop and produce large hail and strong winds. The shear is also allowing a few storms to rotate and prompt tornado warnings this afternoon. Due to the lack of heat and humidity north of Virginia the severe threat will not creep north into the Mid-Atlantic. But, a steady flow off the Atlantic Ocean is pumping moisture into the Mid Atlantic, and those areas are seeing a lot of rain. Some flooding problems are expected. Outside of those areas, things remain very quiet across the US. A system will work across the US this week with rain and storms but not much severe weather. More on this system this evening.
