High pressure ridge will build southwest across the carolinas
today then move off the east coast Thursday. Moisture will
return Thursday with a chance of showers, especially in the
csra. A warm front will move through the area early Friday
followed by a cold front late. Numerous showers and
thunderstorms are expected Friday. It will be slightly cooler
Thursday and Friday with unsettled conditions but warmer and
drier over the weekend.
Near term /until 6 pm this evening/
Early this morning... A weak cold front has pushed south through
the area and will stall near the csra. Mostly clear skies will
continue overnight with light winds. Low temperatures are on
track to drop into the middle 50s.
Today... Ridging aloft and at the surface will dominate the
pattern today providing dry weather with mostly sunny skies.
Despite northeasterly low level winds, the airmass will
moderate quickly behind the frontal boundary. Subsidence
combined with nearly full insolation will promote above normal
temperatures, in the lower 80s.
Short term /6 pm this evening through Thursday night/
Frontal boundary will remain just off to the south of the
forecast area tonight, then will begin to move northward as a
warm/moist front Thursday. Clouds will begin to increase through
the night tonight as moisture begins to lift over the old front.
Weak isentropic lift and low-level moisture flux increases more
on Thursday, and rain chances will be on the increase from south
to north as the day progresses. Moisture will ride over a weak
surface wedge north of the front, which will be retreating through
the day. With the expected clouds and rain, it's possible it
may be cooler during the afternoon in the csra than pee dee or|
east midlands. Stayed close to current temperature forecast.
Warm front will lift further north during the evening and
overnight hours Thursday night. There remains some potential
for a few thunderstorms late Thursday night.
Long term /Friday through Tuesday/
Models have the main cold front and upper level trough moving
through the area on Friday. Timing of the front may not coincide
with peak heating, especially over the western counties. Better
chance for strong thunderstorms will exist in the early
afternoon across the east. By late afternoon, moisture and
instability will be moving out of the area as the front pushes
through. SPC has region in an enhanced risk of severe
thunderstorms for Friday. Behind the front, dry conditions will
move in for the weekend as ridge builds over the area. Another
system will approach from the west on Monday, which will help to
bring another chance for showers and thunderstorms to the
region. Temperatures remain above normal.
Aviation /08z Wednesday through Sunday/
High confidence inVFR conditions throughout the 24-hr taf
The weak frontal boundary has slipped south of the area with
surface winds becoming north-northeasterly. Skies will remain
mostly clear overnight. Fog potential is low given drier airmass
and 20 knot low level jet. Ridging will dominate the area today
promoting dry weather. Clouds and moisture will increase late
tonight ahead of the next approaching system.
Extended aviation outlook... Restrictions likely in showers and
thunderstorms Thursday through Friday night as an cold front
crosses the region.

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 L-36.com. 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 L-36.com 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.
