High pressure will bring dry and seasonably hot weather to the
region for the start of the work week. A strong cold front will bring
increasing rain chances for the middle of the week, then move
east and off the coast by Friday, with cooler drier weather in its

Near term through tonight

anchored by a 594dm upper-level anticyclone, central nc will sit
under the influence of deep layer ridging on Monday, which is a good
thing in terms of limited cloud cover across central nc as the solar
eclipse viewing party commences this afternoon.

The lack of forcing along with warm dry aloft will continue to limit
rain chances, with the better chances on our eastern and western
flanks, in vicinity of the sea breeze near the coast and along the
terrain induced differential heating over the mtns fthls.

Highs in the lower 90s. Lows 70 to 75.

Short term Tuesday and Tuesday night
As of 230 am Monday...

heights aloft fall slightly on Tuesday with the approach of the
northern stream trough and attendant cold front into the ohio and tn
valleys late Tuesday Tuesday night. While we do see the development
of pre-frontal sfc trough in the lee of the mountains Tuesday
afternoon, central nc remains in a void of appreciable synoptic
scale lift. And as such, convective rain chances should remain
rather low and generally confined across the far SE zones in the
vicinity of the sea breeze and across the western part of the state
along the pre-frontal trough. One minor caveat that needs to be
mentioned is a sheared vorticity centered that's currently off the
se coast.

If this feature can hold together as it moves westward over the se
states, where it will encounter the upper level anticyclone, dpva
from this feature could serve to support slightly higher better rain
chances across the southern zones. Will continue monitor will only
slight chance pops for now.

Loss of daytime heating should Tuesday evening should lead to dry
conditions overnight as the cold front doesn't't arrive from the nw
until late Wednesday afternoon.

Highs in the lower 90s with lows in the lower to mid 70s.

Long term Wednesday through Sunday
As of 315 am Monday...

a rather strong cold front will progress slowly southeast and across
central nc Wednesday through Thursday night, perhaps stalling along
the coast as high pressure builds south down the atlantic coast
behind the front. Convection will be on the increase by Wednesday
afternoon in the northwest as the front pulls out of the mountains,
with highest probabilities for precipitation (60%-ish) from
Wednesday evening in the west through Thursday morning east of i95.

At this early juncture, seeing mixed signals in the potential for
severe convection. The strongest low level forcing looks to lag the
best diurnal instability, and while there will be good directional
shear in the low level winds, it will be offset by weak wind speeds
(i.E. ~20kt at h85). Meanwhile, upper diffluence will be fairly
strong, as the entrance region of an 80kt upper jet pulls off the
mid atlantic coast. Highs Wednesday will have time to reach the
lower 90s in the south, while cloudiness and pm cool air advection
will halt the diurnal cycle in the upper 80s across the north and
northwest. Will have only slight chances lingering in the west
Thursday morning, with pops in the east tapering off to slight
chance early Thursday night. Thursday's highs will cooler with lower
humidity as high pressure builds in from the north... Mostly lower
80s. Friday through the weekend will be below normal and dry, with
highs from around 80 across the north to mid 80s across the far

Aviation 12z Monday through Friday
As of 730 am Monday...

fog stratus at krwi and kfay will lift between 12 to 15z, with
generally dryVFR conditions for the afternoon and evening. Will
follow persistence in terms fog and stratus for tonight Tuesday
morning, with lifr to MVFR conditions at krwi and kfay.

Outlook: isolated to scattered diurnal showers and thunderstorms are
expected on Tuesday. A cold front will move through the area
Wednesday and settle near the coast on Thursday providing an
opportunity for adverse conditions during this time period before
returning toVFR for the end of the week and into the weekend.

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.
