Area Forecast Discussion
National Weather Service Newport/Morehead City NC
340 AM EST Sat Feb 16 2019

.SYNOPSIS...
A cold front will move south through the area today and an area
of low pressure will pass by to the south. High pressure will
temporarily build in from the north tonight. Several frontal
boundaries and areas of low pressure will affect the region
much of next week.

&&

.NEAR TERM /THROUGH TODAY/...
As of 340 am Sat...Latest run of GFS/ECMWF show good agreement
between the two, and match up well with current conditions
around the region. Rain shield is just to the west and will
overspread the forecast area through the remainder of the
overnight/early morning hours. Expect widespread coverage this
morning, with strong lift/convergence along boundary sinkinig
south through the forecast area with low pressure passing just
to the south this morning. Categorical PoPs this morning taper
back to chance by later this afternoon as the front sinks
further to the south and the low moves out to sea. Highs temps
will range from the upper 40s to lower 50s along the northern
tier, to the mid/upper 50s across the far south.

&&

.SHORT TERM /TONIGHT/...
As of 340 am Sat...High pressure will wedge in from the north
tonight, allowing for drier and cooler air to filter into the
area. Precip will taper off quickly from northwest to southeast
this evening, with dry conditions after 03Z. Lows will drop into
the 30s inland and upper 30s to lower 40s along the beaches.


&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
As of 340 AM Saturday... Unsettled weather expected through the
period, as numerous frontal systems and shortwaves impact the
region.

Sunday through Monday...A significant positively-tilted upper level
trough will dig into the SW US, allowing for SW flow aloft and
increased moisture over the Southeast and Mid-Atlantic regions
through early next week. Rain chances will increase Sunday afternoon
as the frontal boundary that`s to the of the area, lifts back up as
a warm front with an area of low pressure developing along the
boundary combined with shortwave energy aloft. The best chances for
precip is Sun night through mid-day Monday. Will continue likely
Pops Sun night, then tapering off Mon afternoon/evening as a cold
front pushes through the area. Expect highs in the in the 50s Sunday
and into the mid 50s to lower 60s Monday.

Tuesday through Friday...The 00z model suite have become into better
agreement compared to past model runs, but uncertainty remains with
timing. Overall, weather conditions will remain unsettled with
additional rain and clouds. The area will be under the influence of
high pressure extending down from the north, but this will be short
lived as an areas of low pressure starts to develop over the Gulf
states Tuesday night, and lifts into the TN/OH Valley Wed while
secondary low develops along the NC coast. As the low lifts towards
the New England coast the associated cold will push through the
area, but timing is uncertain. The latest ECMWF pushes the front
through the area late Thu, while the GFS has the front pushing
through Thursday night into early Friday, but keeps the boundary
stalled near the area and deep moisture in place. Will continue high
chance to likely PoPs through Friday, as fronts and areas of low
pressure linger over the area, combined with shortwave energy. Temps
look mild with highs in the 50s to 60s and overnight lows in the 40s
and 50s.
