FIRST ALERT: One round of rain tonight, another round of rain and storm arrives Sunday

MYRTLE BEACH, S.C. (WMBF) - A round of showers and storms tonight will taper off early Friday followed by another round with potentially heavy rain on Sunday.

TONIGHT

A surge of moisture and warmth will arrive in the region overnight and will bring very mild temperatures and increasing rain and possibly thunderstorms. Rain will increase in coverage well after sunset with the best chance of showers and storms from midnight through sunrise Friday. A few heavy downpours and rumbles of thunder will be likely. Overnight temperatures remain very mild in the lower to middle 60s.

FRIDAY

Steady rain will quickly come to an end during the morning hours on Friday. From late morning through the afternoon, clouds will occasionally break with sunshine around at times. The sunshine could energize the atmosphere enough to spark off a few isolated afternoon storms. Rain chances will range from 60% around sunrise and then drop to just 20% from the mid morning through the late afternoon.

The peaks of sunshine will be enough to make for a warm day with temperatures in the middle to upper 70s at the beach and to near 80 inland.

The best rain chance will be early tomorrow. After the morning, we will see rain chances drop... — The best rain chance will be early tomorrow. After the morning, we will see rain chances drop down to 20-30%.(WMBF)

THIS WEEKEND

The weekend starts off mild and dry as the region will be between rain-makers on Saturday. The result will be a mix of sun and clouds with very warm temperatures ranging from near 80 at the beach to the lower to middle 80s inland.

The forecast will once again turn wet by the second half of the weekend. A second system will move into the Carolinas on Sunday, bringing back the potential for widespread showers and storms.

Off and on showers and storms will be likely through the day Sunday with some breaks in between. Some locally heavier downpours will be likely at times along with embedded thunderstorms.

The risk of severe storms remains uncertain at this point, but is something to keep an eye on. Low pressure will take a very favorable track for severe storms to develop and upper level winds will be strong. However, a lack of storm fuel may keep any risk very low. Nonetheless, a little bit of sunshine or warmer temperatures on Sunday could lead to an increased risk of severe storms.

Rainfall totals from Friday through Sunday night will likely average one to two inches across most of the region.
