What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure centered over the western atlantic will extend
westward across the carolinas today. The resulting wind flow from
the south, along with an upper trough approaching from the west,
will lead to increased cloud cover and unsettled weather over the
weekend.

Near term until 6 am Saturday morning
As of 1110 am Friday...

latest surface analysis shows surface high pressure centered
off the mid-atlantic coast with a weakening stationary from
extending across south carolina into georgia. Further aloft,
a ridge of high pressure extends from the subtropical atlantic
northwest across the carolinas into the southern appalachians.

An embedded shortwave in the ridge across western south carolina
this morning will slowly lift north across western nc this
afternoon and evening.

As a southerly flow continues to become established, low level
moisture and instability will increase especially across the
southern and western piedmont and the sandhills, with a more
stable air mass across the east and especially northeast. Widely
scattered showers and a few thunderstorms will develop early
this afternoon in an arc from the southern coastal plain
northwest to the triad with somewhat more numerous showers and
thunderstorms lifting north across the western piedmont later
this afternoon and evening. Convection allowing models highlight
the ongoing activity in south carolina well this morning and
support the evolution noted above.

Spc has central nc outlined in generally thunder for today and
don't expect any severe weather given weak instability and
light southeast to southwest flow with bulk shear values of
around 10kts. Locally heavy rain resulting will be a limited
threat. Highs today will range in the lower to mid 80s with lows
in the upper 60s to around 70. -blaes

Short term 6 am Saturday morning through Saturday night
As of 255 am Friday...

moisture will continue to deepen across W nc, as the influence of
both the surface and upper ridge axes across the area decrease. Deep
layer wind flow strengthens considerably from the sw, evident from
925 mb up through 700 mb and strongest over W nc, as broad troughing
aloft crosses the great lakes region and becomes loosely linked to
low pressure over the gulf. Shower and afternoon storm chances will
increase Sat morning across the NW half of the forecast area, and
while pops will be non-zero elsewhere (the SE half), the gulf low
may serve to build the ridge extending through nc Sat sat night,
resulting in a greater chance of neutral to sinking air through the
column. Highs from the lower 80s NW to the upper 80s over much of
the SE half of the forecast area, under partly (se) to mostly (nw)
cloudy skies. Shower storm chances will hold through the evening
mainly NW but will drop overnight as models indicate a band of lower
pw spreading northward through nc late. Expect considerable mid and
high clouds to persist, but will trend down to no pops late sat
night. Lows within a degree or two of 70 everywhere. -gih

Long term Sunday through Friday
As of 235 pm Friday...

latest longer range forecast generally on track.

Sunday will start out fairly dry for central nc as the area will be
between a frontal zone to the north and alberto to the south.

That frontal zone to the north will become more active with the
heating of the day and possibly impinge upon our northern and
western counties by late afternoon.

Overnight Sunday night into Monday morning the first wave
of tropical moisture will arrive from the south with some upper
level support and this could linger in the area through early
Tuesday morning. Periods of heavy rain can be expected during this
time, particularly across southern and eastern areas. This wave will
move out to sea on Tuesday morning with drier conditions later
Tuesday. The next wave of tropical moisture will enter the
region Wednesday into Thursday, but this will depend upon the
actual track of the remnants of alberto. Drier weather returns
Friday, but with more sunshine, temperatures will rise to
around 90f.

With deep tropical moisture in place from Sunday through
Thursday, torrential rainfall with any convection will have the
potential to produce flash flooding across central north
carolina. Urban and small stream flooding risk will be highest
early on with river flooding possibly becoming a problem later
in the period depending on actual rainfall totals.

Aviation 19z Friday through Wednesday
As of 230 pm Friday...

vfr conditions are noted across much of central nc this afternoon
with the exception of some MVFR CIGS across the triad and in a
few locations in the sandhills and southern coastal plain where
some scattered convection is ongoing. Scattered showers and an
isolated thunderstorm or two will develop in an arc from the
southern coastal plain west and northwest across the sandhills
into the western piedmont, potentially impacting the fay, gso
and int terminals with a much more limited threat at the rdu and
rwi terminals. Convective coverage will wane this evening with
a period ofVFR conditions expected to dominate late this
evening and overnight. However, sub-vfr conditions, mainly with
low CIGS are expected to return overnight after around 06z at
the fay terminal and a little later, maybe after 08z at the
other terminals with the greatest confidence of MVFR to ifr cigs
at int, gso and fay. Surface winds from 160 to 200 degrees at 5
to 10kts today will decrease to less than 5 kts overnight
before increasing to around 10 kts on Saturday with a few gusts
to near 15 kts possible during the afternoon.

Looking beyond 18z Saturday, low clouds and reduced CIGS will
lift giving way to a period ofVFR conditions before scattered
afternoon and evening storms develop. After a period of morning
stratus another round of scattered storms on Sunday. Widespread
adverse aviation conditions are expected Monday into Wednesday
as widespread showers and thunderstorms are expected. -blaes
