More rain and storms… Highs will warm into the upper 80s this afternoon but it will feel more like the mid 90s with the humidity. We will see a mix of partly to mostly cloudy skies today with scattered showers and storms as a warm front lingers to our north. Severe storms are not expected but thunderstorms and heavy downpours are possible.
A cold front will slowly push into the region over the next few days. Expect a mix of clouds with scattered showers and storms tomorrow and Wednesday. Highs will reach the mid to upper 80s, still above normal for this time of year.
Hurricane Florence will approach the Carolina coastline on Thursday. Based on the current forecast track, we will see widespread rain and very strong winds on Thursday and Friday. Significant flooding is expected with several inches of rainfall combined with coastal flooding and storm surge. We will be fine tuning the timing and impacts through the week.
Florence will weaken once over land but could linger into the weekend.
