000 FXUS62 KRAH 160544 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 145 AM EDT Sat Sep 16 2017 .SYNOPSIS... Weak high pressure over the region will remain in place through the weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 1021 PM Friday... Weak surface high pressure (1022 mb) extended from NY/PA down the Appalachians this evening. A weak trough was over central NC. The latest data indicated only patchy mid level clouds remained over our region. Otherwise, the skies were generally clear. Temperatures were already 63-69 north and west, 70-75 south and east. Some patchy ground fog was developing over the Coastal Plain. For the overnight, conditions appear favorable for generally patchy ground fog. Lows expected to be in the upper 50s to lower 60s north, ranging into the upper 60s SE. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... As of 130 PM Friday... A lee trough within a very weak surface pattern east of the Appalachians will get overwhelmed by both high pressure over the central Appalachians and the cyclonic flow around Jose. A light northerly low level flow and generally dry and warm conditions will result on Saturday. There is a slight chance of a shower over the Coastal Plain in the afternoon, capped by an inversion around 10K feet. && .LONG TERM /SUNDAY THROUGH FRIDAY/... As of 1155 AM Friday... Cloudiness will increase early in the extended, especially from the Coastal Plain eastward, given the offshore track of Jose, which is progged to lift north up the mid-Atlantic early next week. We could see a few showers develop in the resulting moist northerly flow east of I95 on Sunday and Monday. Tuesday through Friday look to remain generally dry and continued warm and relatively humid as a subtropical ridge sets up west of the area. Highs will be consistently in the low and mid 80s through Tuesday, warming to mid and upper 80s Wednesday through Friday. Morning mins will be in the low to mid 60s. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...

As of 145 AM Saturday... A weak area of high pressure will maintain VFR conditions across central NC through early next week. The exception will be during the early morning hours when areas of fog will reduce the visibility into the MVFR range, and briefly into the IFR category at a few spots. Any fog the develops will lift/dissipate by 14Z each morning. Sfc winds today will be light (less than 10 kts). The sfc winds should become a bit breezy Sunday, primarily east of highway 1, where a nly sustained wind around 10 kts probable and some gusts in the 15-20kt range.
