000 FXUS62 KRAH 241720 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 120 PM EDT WED AUG 24 2016 .SYNOPSIS... High pressure will extend across the region through the week. Temperatures and humidities will gradually rise through late week. && .NEAR TERM /THROUGH TONIGHT/... As of 1045 AM Wednesday... Little change required to the near term forecast. An area of high pressure extending across central NC will result in hot and dry conditions this afternoon. A thin layer of moisture trapped below a mid level subsidence inversion will result in patches of mid level cloudiness at times. Subsidence and a relatively dry air mass aloft will inhibit convective development across most of the area. The exception will be in vicinity of the Yadkin River valley where a stray shower or storm may develop in a narrow zone of low level moisture convergence. Afternoon temps in the upper 80s to around 90 appear on track. Tonight, overnight temps will cool back into the 60s under mostly clear/partly cloudy skies as the area of high pressure maintains control of our weather. && .SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/... As of 145 AM Wednesday... The surface ridge axis will push offshore leading to a WSW flow aiding warming as the mid level ridging strengthens over the southern Appalachians. Continued mainly sunny, dry, and becoming hot Thursday. Highs in the upper 80s to mid 90s N to S. Lows in the upper 60s to lower 70s. && .LONG TERM /FRIDAY THROUGH TUESDAY/... As of 245 AM Wednesday... Chances of rain remain minuscule in the extended period. A weak and moisture-starved surface front edges southeast and into NC on Friday and progresses south of the area by later Saturday. Concurrently, a strong upper ridge builds north and parks directly overhead through the weekend. High temps on Friday will max out in the low to mid 90s, and very modest post-frontal cool air advection in easterly flow over the weekend will be offset by the building ridge aloft to allow highs to reach 90 to 95 Sat and Sun. The upper ridge slowly deamplifies, but maintains its dominance through midweek, with dry and slightly above normal temperatures - within a couple degrees north or south of 90 - lingering through mid week. && .AVIATION /18Z WEDNESDAY THROUGH THURSDAY/...

As of 120 PM Wednesday... There is a high probability that VFR conditions will persist across central NC through Thursday night. The exception will be pockets of MVFR/IFR visibility between 09Z-12Z, mainly in the sandhills and coastal plain. This possibility appears highest in vicinity of KRWI. Otherwise, an area of high pressure will maintain dry weather with light wind conditions. This area of high pressure is expected to maintain its influence over our region through early next week. This suggest an extended period of VFR conditions, aside from patchy early morning MVFR/IFR fog or low clouds.
