What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Surface high pressure over the mid-atlantic will extend across
the region into the weekend. A cold front will approach the
area from the west early next week.

Near term through tonight
As of 245 pm Thursday...

a minor S W traversing sewd across central nc this afternoon will
exit our region prior to sunset. Rising heights aloft in the wake of
this feature will strengthen the low level ridge over our area
tonight. Thus, expect another starry night with temperatures falling
through the 50s this evening, and into the 40s overnight.

Short term Friday through Friday night
As of 245 pm Thursday...

the strengthening high aloft and associated subsidence coupled with
the sfc ridge will maintain a dry atmosphere across central nc
Friday and Friday night. This dry air will support diurnal
temperature swings of 30-35 degrees. The warming aloft in
conjunction with the ridge at the surface will translate to mild
afternoon temperatures in the mid-upper 70s, with a few locations
across the far south possibly reaching 80 degrees.

While temperatures will be in the 70s late Friday afternoon, the dry
air in place will permit temperatures to cool into the 60s early
Friday evening, and solidly in the 50s by midnight. Minimum
temperatures in the upper 40s to around 50 should be common.

Long term Saturday through Thursday
As of 255 pm Thursday...

mid-upper ridging now over the western gulf will continue to amplify
as it builds up and east across the atlantic seaboard, to finally
move off the coast late this weekend. Meanwhile, downstream lies a
strong trof which is forecast to deepen as it moves east across the
plains, and we still have the potential for a cutoff low to separate
from the trof over the tennessee or the lower mississippi valley
Sunday night. If this low does indeed cut off (basically the gfs's
solution), it would enhance the chance for stronger, perhaps severe,
convection in the Monday night early Tuesday time frame.

At the surface, high pressure over the mid-atlantic states will
gradually shift offshore, with return flow producing moisture
advection and increasing cloudiness ahead of an approaching cold
front Sunday night in the west, and spreading over central nc on
Monday. Showers will become likely by late day Monday in the west,
with likely pops spreading to the eastern piedmont and coastal plain
Monday night. Most of the convective activity will end by later
Tuesday, with potential for some lingering instability showers in
the cold air advection behind the front Tuesday night. Dry and
cooler air will settle into place for midweek.

Temperatures this weekend will be glorious for attending outdoor
activities, with plenty of Sun to accompany highs in the mid and
upper 70s. Hihgs should also reach mostly mid to upper 70s on Monday
with warm southerly flow to offset the lack of sun. Highs Tuesday
should reach upper 60s to lower 70s, with the cooler airmass
stalling highs in the 60s on Wednesday and Thursday. Morning mins
will be in the low and mid 50s through Tuesday morning, with mins in
the 40s on tap for Wednesday and Thursday.

Aviation 18z Thursday through Tuesday
As of 135 pm Thursday...

there is a high probability ofVFR conditions to persist across
central nc through 00z Saturday as high pressure at the surface and
aloft controls the weather across central nc.

The sfc high will drift offshore Saturday. The return low level flow
Saturday night will moisten the low level air mass, leading to the
potential for patchy fog with MVFR ifr visibilities, primarily
between 09z-13z Sunday.

The approach and passage of a cold front Sunday night through
Tuesday will enhance the probability of subVFR parameters,
primarily lower ceilings. The probability for scattered convection
will also increase late Monday into Tuesday.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. 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.
