Area Forecast Discussion
National Weather Service Raleigh NC
648 PM EDT Sat May 12 2018

.SYNOPSIS...
A persistent Bermuda high pressure system will extend into the
southeastern U.S. through the weekend while a stationary front
lingers to the north. A low pressure system will develop over
the Gulf of Mexico on Sunday and drift slowly north early next
week.
&&

.NEAR TERM /THROUGH TONIGHT/...
As of 648 PM Saturday...

The extension of the Bermuda high into the SE US, coupled with the
expansive upper level ridge axis that extends across much of the
southern CONUS, will result in hot and mostly dry conditions today.

While it took a little longer than originally expected, we are now
seeing a few storms going up over the Sandhills, in proximity to the
sheared remnants of a shortwave impulse that crossed the southern
Appalachians last night. While both shear and forcing are weak, if
one of the updrafts can develop a tall enough core, DCAPE values of
1000 to 1100 Joules/Kg could support isolated downburst/thunderstorm
wind damage.

Afternoon convection will die off quickly after sunset with mostly
clear skies tonight. Lows in the mid 60s.

&&

.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
As of 303 PM Saturday...

Sandwiched between a cold front progged to stall near the Washington
metropolitan area and a developing upper low invof of the eastern
Gulf Mexico, strong mid/upper level anticyclone centered over the
south-central CONUS will continue to extend east across the
Carolinas, keeping it mostly dry on Sunday. The exception could be
across the southern Coastal Plain counties, where hi-res CAMs show a
little seabreeze activity trying to move inland into the far SE
zones. Otherwise, continued southerly flow around the Bermuda high
pressure cell will support highs of 90 to 95, the warmest Mother's
Day we've seen in over 75 years(see NWS Raleigh Facebook and Twitter
social media pages for additional Mother's Day climatology). Mild
overnight lows in the mid 60s.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
As of 245 PM Saturday...

...Unsettled Weather with Above Normal Precipitation Chances
Expected during the Middle and End of the Upcoming Work Week...

The upper-air pattern at the beginning of the long term period on
Monday will feature an upper-level low over the northeastern G Gulf
of Mexico and an elongated upper level ridge axis from the sub-
tropical Atlantic into the Tennessee Valley with the main westerlies
moving across the Ohio Valley and Mid-Atlantic. NWP guidance
generally shows the upper low shifting slowly northwesterly with
time, reaching the lower Mississippi Valley on Wednesday and then
opening up into a trough across the Ohio and Tennessee Valleys on
Friday before shearing out on Saturday.
During this period, a subtropical high will become established
across the western Atlantic which combined with the upper low/trough
to the west, will result in a deep southerly flow across the
Southeast. The plume of moisture with origins in the Carribean will
interject precipitable water values of 1.75 to 2.0 inches across
central NC for most of the long term which is between 2 and 3
standard deviations from normal. This will result in unsettled
conditions with periods of showers and thunderstorms with locally
heavy rain in a pattern that raises concern for flash flooding,
especially in urban areas. Will need some time to refine the
corridor of heaviest rain across the Southeast, but it needs to be
watched.

In terms of sensible weather, Monday will likely be the hottest
and driest weather of the long term period with just isolated
thunderstorms and highs in the lower 90s. The threat of showers
and storms increases on Tuesday and likely peaks on Wednesday
and Thursday, nearly supporting likely PoPs. Highs will range in
the lower to mid 80s with lows in the 60s. Increasing
uncertainty with how the pattern will evolve supports lower PoPs
for Friday and Saturday and near to just above seasonable
temperatures. -Blaes

&&

.AVIATION /23Z SATURDAY THROUGH THURSDAY/...
As of 648 PM Saturday...

Isolated convection across the NC Sandhills may briefly impact KFAY
through 02z, before dissipating. Otherwise, aside from some patchy
fog around daybreak, expect predominately VFR conditions through 00Z
Monday.

Outlook VFR conditions are expected to persist into Monday. Deep
southerly flow between an upper level low that will move slowly
north through the Deep South and Bermuda high pressure over the
western Atlantic, will draw tropical moisture into the region
Tuesday through Friday. This will result in numerous to widespread
shower and storms and associated sub-VFR CIGS and VSBYS restrictions
each day through the period.
