Increasing chance of rain until the weekend

MYRTLE BEACH, SC (WMBF) – High heat and humidity will lead to increasing rain chances through the end of the week and into the weekend. Locally heavy rains and some drought relief are likely. A weak cold front will move into the Carolinas and remain there from tonight through the end of the week. This front, combined with the brutal humidity, will produce intermittent showers and storms. There is a risk of intermittent locally heavy rains each day.

WEDNESDAY

We are under a different Heat warning for today, with the heat index expected to reach 105-110° this afternoon. The abundant humidity continues to create a muggy feeling when you step out the door this morning.

The probability of rain is higher today than in recent days. A cold front is approaching the Carolinas and will trigger some showers and thunderstorms in the morning.

We’re increasing the chance of rain to 40% today as highs rise to above 30 degrees on the beaches and below 35 degrees inland. While widespread rain is unlikely, some areas will see isolated heavy showers and frequent lightning today. Be sure to download the First Alert Weather app to check radar throughout the day.

POTENTIAL HELP WITH DROUGHT

The weak cold front responsible for today’s storm threat will linger over the region, leading to increasing chances of rain for the rest of the week.

The latest data this morning continues to suggest that the chance of precipitation is highest from Thursday to Saturday, with a 60 percent chance of showers and thunderstorms on each day.

Just like last week, it will be difficult to pinpoint the highest rainfall totals, but some areas will again see some beneficial rainfall. Although rain is not expected all day, showers and thunderstorms may develop at any time during the day, which could result in locally heavy rainfall and frequent lightning.

Severe to extreme drought continues to prevail in most parts of the region. Average rainfall amounts in the region could be between 5 and 10 centimeters through Sunday. While all areas are not guaranteed to receive that much rain, the likelihood of enough rain to at least partially alleviate the ongoing drought continues to rise.

Again, isolated, very heavy rainfall could cause short-term, small, local flooding every day.

As clouds increase and the probability of rain increases, temperatures begin to drop, with afternoon highs falling to 30 to 40 degrees Celsius.
