This round of seasonably cool weather will be short-lived, as another surge of warmer air ushers back into the Carolinas overnight tonight into Monday as this area of high pressure traverses eastward over the Atlantic. This high will give way to an approaching cold front out of the west, setting up a breezy south-southwest wind as a result. Monday is still poised to remain dry throughout the day; however, an evening or overnight shower can pass through the region as this weakening cold front shifts across the Carolinas.
With the passage of another cold front early this week, Tuesday and Wednesday will return to colder weather as highs struggle to reach 50 for some. An upper-level trough digging eastward through the central United States and the Mississippi River Valley Tuesday into Wednesday will also spur the development of another storm system in the Southeast by the middle of the week. This system should have the best chance of producing measurable rainfall across the Triangle, perhaps even with some soaking downpours.
There is lower confidence for the forecast looking ahead to the late week. High pressure should have an opportunity to strengthen across the Northeast on Thursday, extending far enough southward to keep the viewing area dry, though another storm system could generate out of the lower Mississippi River Valley on Friday into Saturday, leaving the possibility for some passing showers late in the week on the table.
Enjoy the rest of the weekend!
