Area Forecast Discussion
National Weather Service Raleigh NC
213 AM EDT Sat Sep 23 2017

.SYNOPSIS...
High pressure centered over the Great Lakes and northern Middle
Atlantic states will extend south into our region through early next
week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 210 AM Saturday...

Patchy fog will again be possible this morning during the pre-dawn
hours in fog prone areas, with generally clear skies and calm winds.
Otherwise, quite weather is expected today, as surface high pressure
extends southward into our area from the Great Lakes and Northern
Mid Atlantic states. High temps will again be in the mid to upper
80s, with a few locations touching 90.

Dry weather is expected to continue tonight with surface high
pressure continuing to extend into our area. 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 /06Z SATURDAY THROUGH WEDNESDAY/...
As of 135 AM Saturday...

24 Hour TAF Period: Surface high pressure will extend southward into
NC today, generally resulting in VFR conditions. However, patchy sub-
VFR visbys will be possible this morning, mainly during the pre-dawn
hours. Confidence is not high enough to include in the TAF though,
except at fog prone KRWI, where MVFR-LIFR visbys are expected.

Outlook: There is a chance of sub-VFR conditions mainly at eastern
TAF sites early to mid next week, when moist northerly flow on the
west side of Tropical Cyclone Maria will likely overspread ern NC.

&&

.RAH WATCHES/WARNINGS/ADVISORIES...
None.
