000 FXUS62 KRAH 231417 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 1015 AM EDT Sat Sep 23 2017 .SYNOPSIS... High pressure centered over the Great Lakes and northeast states will extend south into our region through early next week. && .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
As of 1015 AM Saturday... A weak broad upper trough over the SE US will drift west today and tonight with central NC becoming under the increasing influence of the stacked anticyclone expanding eastward into the Mid-Atlantic Region. This will allow for dry conditions and a nearly cloud free sky, aside from some very thin patchy cirrus clouds. With no change in airmass, temps today and again on Sunday will follow a persistence forecast, with afternoon highs 85 to 90, perhaps a degree cooler than yesterday with sfc winds expected to maintain a more northerly/northeasterly component. Some patchy fog will again be possible with overnight lows generally in the lower to mid 60s, with even a few upper 50s in the cold rural areas.

&& .SHORT TERM /SUNDAY AND SUNDAY NIGHT/... As of 210 AM Saturday... Another high pressure will extend south through the area Sunday and Sunday night. Expect sunny and warm conditions Sunday with Highs 83- 88. Clear skies are forecast Sunday night with lows in the 60s. && .LONG TERM /MONDAY THROUGH FRIDAY/... As of 210 AM Saturday... The main weather story continues to be the subtle westward shift in the operational models and official NHC track regarding TC Maria for the middle of next week. Despite this subtle westward shift, the system is still forecast to be far enough to our east to preclude any significant impacts on our sensible weather other than a possible increase in the low level NE flow, mainly down east mid- week. Late week, a strong cold front and mid/upper trough is forecast to drive SE - pushing the TC threat quickly away from the eastern U.S. Overall, we have high odds of no precipitation for the next 7 days. Temperatures will remain warm until late week, when the pattern changes and the NW flow begins. Highs Friday should fall back 5-8 degrees from the mid to upper 80s expected most of the week. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...

Patchy MVFR ground fog is possible at all terminals tonight, with some periods of IFR/LIFR at KRWI. Outlook: Generally VFR conditions are expected through mid-week The approach of Hurricane Maria towards the NC coast will result in breezy conditions by Wednesday with northerly wind gusts as high as 25 to 35 kts, strongest at eastern terminals. .
