900 pm edt Wed oct 17 2018

High pressure will build over nc tonight through Friday. Another
cold front will cross the area on Saturday, before much cooler and
drier air arrives on Sunday.

Near term through tonight ...

as of 900 pm Wednesday...

jet stream cirrus cirrostratus seen on the latest satellite data
extend from mo il east southern wva and va and nc. It appears that
some of this high level moisture will continue to extend eastward
across nc through the overnight hours. Otherwise, fair skies and
cooler tonight. Lows generally 40 to 45.

Short term Thursday and Thursday night
As of 235 pm Wednesday...

expect plenty of sunshine Thu followed by clear skies Thu night
within deep layer subsidence and dry near-surface air. A few high
clouds will streak across the region with still-swift mid level flow
between the departing trough off the canadian maritimes and the flat
ridge centered over fl. Cold air advection will persist but with
decreasing wind speeds as the surface ridge passes over the ohio
valley. The cool start to the day will offset the fair skies,
yielding highs about 7-10f below normal, from around 60 N to the
upper 60s s. The high will shift just to our north Thu night with
very light to calm winds and low dewpoints, the latter of which
should limit frost potential despite good radiational cooling. We
should see lows in the upper 30s N to lower 40s s, and some mid 30s
are possible in rural spots across the north. -gih

Long term Friday through Wednesday
As of 230 pm Wednesday...

Friday will begin with surface high pressure right on top of central
nc with a flat ridge aloft centered over the florida peninsula. As
the day progresses, the high will shift eastward and introduce some
clouds by Friday afternoon filling in from west to east. Dry weather
expected with high temps in the low 60s across the NW piedmont to
upper 60s in the southeast.

By Friday night a wave coming from the southwest will help fill in a
frontal zone with parent high over quebec. This front will then push
eastward into the state on Saturday with precipitation expected to
overspread the area by Saturday afternoon. With an upper level
trough over the great lakes rapidly digging south, the surface front
will pick up speed and become very progressive, pushing through the
state Saturday night and beginning to clear out by sunrise on
Sunday. With some warm air advection out ahead of the front highs on
Saturday will range from the mid 60s in the NW to lower 70s in the
southeast. By Saturday night the cold air will have begun to filter
in but expect a NW to SE gradient ranging from the mid 40s to near
50 degrees.

Thicknesses fall out and temperatures really begin to drop with the
airmass change on Sunday so we can expect a 10 degree drop in high
temperatures for Sunday only reaching the upper 50s in the triad and
va border counties to middle 60s in the southeast. Sunday night into
Monday there will be the potential for areas north and west of the
triangle to receive their first frost of the year as low
temperatures are expected to dive into the mid to upper 30s but with
nearly ideal radiational cooling and dewpoints only in the low 30s
those lows could drop even a couple degrees below that but will
likely stay above the freezing line.

Another continental high pressure will take over for early next
week, keeping conditions cool and dry. While temperatures will
remain cool, a decrease in cold air advection on the front side of
the high will stabilize overnight temperatures back into the low to
mid 40s and mitigating any further threat for frost. Daytime highs
generally in the 60s with 40s at night.

Aviation 00z Thursday through Monday
As of 720 pm Wednesday...

24 hour TAF period:VFR conditions are expected to continue through
the 24 hour TAF period as surface high pressure builds into the
area. This will continue to usher in dry air and quite weather,
resulting in skies becoming mostly clear overnight and continuing on
Thursday. A northerly component to the winds will continue through
the period, with wind speeds 10 kts or less (with more light and
variable to calm at times overnight).

Outlook:VFR conditions will persist into Fri evening as high
pressure dominates. There is a good chance for sub-vfr conditions
and increased rain chances areawide 06z Sat through 03z Sun (fri
night through Sat evening) with approach and passage of a cold front
from the west.VFR conditions are very likely to return late sat
night, holding through mon. A period of strong, gusty winds is
expected late Sat night through Sun morning.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
