Marine Weather and Tides
Apex, NC

Version 3.4
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.

535 pm edt Sat jun 23 2018

A weak surface trough will linger over central nc this weekend. A
weak cold front will cross the region Sunday night through early
Monday. This will be followed by a ridge of high pressure which will
extend across the region through midweek.

Near term through tonight
As of 535 pm Saturday...

we cancelled the severe thunderstorm watch early.

Most of the organized convection has been NE of our region. There
were still a few storms that extended from near krwi to scotland
neck that are in a favorable region for upscale growth. Otherwise,
only isolated activity is expected. We did drop pop from likely to
low chance (70 to 30) due to lack of activity.

Short term Sunday and Sunday night
As of 300 pm Saturday...

h5 heights and low level thicknesses rebound across the area on
Sunday in the near-zonal flow aloft, reinforcing the lee trof over
the area. Temps will be in the low to mid 90s, and the far southern
tier counties could reach upper 90s. Low level forcing will be
meager, basically convergence east of the lee trof, but soaring
instability as we heat up would be conducive to convection given
weak disturbances riding the westerly flow across the mountains.

Timing and strength of these disturbances is low confidence at this
point , but we could see some modest increase in convective coverage
late Sunday into Sunday night. Lows Sunday night will be persistence
again, 70 to 75.

Tns in the zonal flow aloft coupled with the passage of a
weak surface front trough from the NW could result in an uptick in
pops late Sunday and into Sunday night. For now will carry low
chance pops into Sunday night, but later forecast updates may need
increase pops. Overnight lows 70 to 75.

Long term Monday through Saturday
As of 325 pm Saturday...

a backdoor front will slide southward toward and into the region
Monday through Tuesday. There is still some uncertainty with the
progression of the front and how long it will linger over portions
of central nc. Those factors will obviously impact temperatures and
precipitation chances through Thursday. The piedmont trough will
once again set up Thursday and Friday as the high moves well off to
the northeast over the atlantic. Aloft, central nc will be situated
in the base of an eastward progressing, slightly amplified trough on
Monday, with high pressure over the gulf coast and another
developing low over the northern high plains. As the trough shifts
offshore Monday night, high pressure will ridge northward into the
region through Tuesday night. Meanwhile, the aforementioned
developing low will move east into the great lakes region. Although
the trough will deamplify some as it moves through the great lakes
toward new england, it will still extend southward into the
carolinas as the high shifts westward, resulting in a deeper
southerly flow advecting warm moist air into the region. As a
result, expect the usual diurnal convection chances through mid-
week, especially along and south of the front, with increasing rain
chances toward the end of the week as the front lifts through the
area and the upper trough swings through.

Temperatures: a bit of a roller coaster ride for highs, decreasing
from upper 80s mid 90s on Monday to mid to upper 80s on Tuesday then
increasing again into the low to mid 90s by the end of the week.

Lows will follow the same pattern, dropping into the mid to upper
60s by Tuesday night before increasing again into the mid 70s.

Aviation 18z Saturday through Wednesday
As of 300 pm Friday...

24 hour TAF period:VFR conditions are expected, with scattered late
afternoon evening convection in the northeast ending after 00z.

Southwest winds gusting to 15kts this evening will likewise diminish
to 6kts or less overnight. Widely scattered convection is expected
again Sunday afternoon, predominantly after 18z.

Outlook: mainly diurnal convection and related sub-vfr conditions
are expected Monday. A cooler and more stable airmass will build in
behind a front pushing through late Monday. This will limit
convection to only isolated late day activity Tuesday through

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.
