Active Week With Heavy Rains and Possible Flooding

An active week is in store with two systems bringing the opportunity for heavy rains and flooding, and there may even be a chance for wintry weather for parts of the Carolinas

Clouds are increasing across the Carolinas as an upper level trough continues to dive into the center of the country, bringing moisture northward from the Gulf of Mexico and allowing an area of low pressure to organize. 

The system will rapidly strengthen and will bring periods of very heavy rains to the Carolinas. Flash flooding may become an issue, especially overnight Monday into Tuesday. 1-3 inches of rain is likely across the entire Carolinas through Tuesday evening.

The good news is the severe weather threat will remain low with the expected storm track. The bad news is temperatures will remain cool with a northeasterly wind bringing cooler air from the Atlantic. 

The images below shows the storm progression from the National Weather Service.

As the system is pulling away Tuesday evening, snow showers are possible across the mountains. Minor accumulations are possible in areas above 4000 feet.

If that was not enough rain for you, a second system will round the base of the upper level low and will bring another chance of rain to the Carolinas for Thursday into Friday morning. There is still some uncertainty with the exact evolution of this second system, but models are all showing another chance of very heavy rain. This second round of rain could bring an additional 1-2 inches of rain.

Portions of the Carolinas may see a little bit of wintry weather Thursday morning briefly with temperatures hovering around freezing. Mountains, foothills, and western piedmont locations should be around freezing on Thursday morning, and with light rain possible, there may be a little bit of freezing rain. The event, if it occurs, would be very short lived.

The weather prediction center is showing very heavy rain throughout the entire southeast through the next five days. Most areas are expected to see 2-4 inches of rain, with isolated higher amounts. Flooding may become an issue; however, the good news is the rain should not fall all at one time.

I will continue to monitor the situation and will keep you updated.
