RALEIGH, N.C. (WTVD) -- Short range modeling has increased storm coverage slightly as we head into the afternoon. Storm chances will be highest just to the south and east, and may become more widespread there.
Nevertheless, with very strong instability and lowering 500 mb heights throughout this period, any storms will be capable of heavy downpours, frequent lightning, and a strong wind gust. Any storms depart late evening, leaving behind mostly clear skies and seasonable lows in the lower 70s.
Another weakening front will push southward through the mid-Atlantic tomorrow. However, modeling keeps the strongest energy associated with this to our north and leaves us dry with just some clouds around at times. Nevertheless, a hot and humid day is in store; dew points should remain in the low to mid 70s, with highs reaching the low to mid 90s.
A dry evening will be in store, though overnight lows will struggle to dip below the upper 70s.
Yet another frontal boundary should push southward on Friday, this time reaching the Triangle. With humid air in place and plentiful forcing along the front, showers and thunderstorms will return during the afternoon and evening hours. A strong to severe storm or two cannot be ruled out, with torrential downpours and strong wind gusts being the main threats. Behind the front, a brief but refreshing decrease in humidity will be in store, with dew points in the mid 50s not out of the question. Temperatures will cool slightly as well, with highs in the upper 80s.
Unfortunately, this break is likely to be short-lived as the potential is there for a low pressure system to spin up along the boundary on Sunday as it stalls to our south, with additional energy aloft coming southeastward toward the Carolinas. Where any potential low ends up will dictate how wet it may be, and how much sun we can manage to see. Overall it looks like another generally unsettled day with higher humidity back in place.
The front lingers nearby into Monday; the European has it just to our south while the American model is close enough to keep the rain chance going. Additional energy coming into the Tennessee Valley by the end of the day tracks eastward along the boundary into Tuesday, keeping rain chances elevated.
Have a great evening!
Tomorrow will be hottest day of the year
