Pinpoint Weather: Dangerous heat and humidity expected, Tropical Storm Danny makes landfall in South Carolina

Weather Blog

The air has a good deal of moisture in it and the temperatures will be in the low to middle 90s which will allow the feels like temperatures to approach 100° at times on Tuesday and Wednesday afternoons.   There will be the potential for storms to pop up in the afternoon as the region as well as the hot air with all that moisture in it rises into the sky.  Our main concern needs to be our ability to stay cool and safe.  Here are some safety tips to keep in mind.

High pressure overhead will be in control and should help to keep a lid on the developing or towering cumulus clouds that may develop into strong storms Tuesday and Wednesday…but if they do evolve in the heat of the day, expect some brief rounds of heavy rain and some minor flooding. Temperatures will be in the middle to upper 80s on Thursday as the region begins a rather rainy period.

There is also a tropical disturbance that will be making landfall in South Carolina today or tonight. At 3 pm today this disturbance became our fourth named storm of the Atlantic Season, Danny. This feature will not directly impact the Commonwealth as the general track will bring the cyclone inland near Charleston SC then into northern Georgia and SE Tennessee, but there may be some moisture cast in our direction that will aid in the development of some storms.  High pressure in place should direct most of the moisture away, but we may get some, so that needs to be addressed.  Officailly Danny made landfall just north of Hilton Head on Pritchards Island around 8 pm. Sustained winds at 40 mph. Moving inland at 16 mph.

There will be a cold front that arrives by the weekend, ahead of it will be the possibility for some rainy weather starting Thursday.  The rain will be likely, and will persist into the weekend. The actual front will help corral the moisture from the south and west and our mountains and heat will do the rest.  Rain should be heavy at times and there will be a chance for some localized flooding early with more widespread rain and possible flooding over the holiday weekend.  Since it is only Monday and there is a tropical system to our south, the models will be switching up a good deal. Right now, it would be wise to get ready for some rain starting Thursday and lingering into the weekend.

Tomorrow, the 29th of June, marks the 9th anniversary of the Derecho that devastated the region.  Strong, straight line winds pushed through the Commonwealth starting at around 8pm on June 29th 2012. Thousands lost power for days amid one of the hottest periods in our region’s history.
