GREENVILLE, N.C. (WITN) - The rise in heat will start to become more noticeable as we wrap up the weekend, with highs on Sunday reaching the mid 80s. Starting off the day under mostly sunny skies will definitely help the heating process along, but we’ll also get the heating benefits of an incoming cold front compressing the air mass (and thereby heating it up) to our west. Heat driven showers and storms will try to develop in the afternoon, so the warmer we get, the better chance we have of seeing our summer time pattern of rain set up.

The cold front will move in late Monday night, again leading to relatively hot weather to start the work week. The front’s late arrival and weak state upon arrival time will pay big dividends, limiting our chances of seeing severe weather. Thunderstorms are still expected along the frontal boundary, but because those storms won’t show up until well after sunset, they won’t be able to feed off the peak heat of the day. Highs Monday will reach the upper 80s with dew points in the mid 60s making it feel more like the low 90s. Winds out of the southwest will blow in at 7 to 12 mph with gusts reaching up to 15 to 20 mph. Once the front clears our coast (expected to happen in the predawn hours of Tuesday morning) our skies will turn mostly sunny for the next several days, ushering in the upper 80s with dew points pushing the “feels like” temperature into the 90s. Heat driven storms will become more common by Thursday and Friday
