751 pm edt Sun sep 15 2019

Warm high pressure will linger near the region through Tuesday
before a cool front moves through on Wednesday. Dry high pressure
then returns for the latter half of the week.

Near term through Monday
As of 745 pm edt Sunday... Forecast is still on track. Updated fog
mention for overnight for the 00z tafs. Guidance is trending a
little less foggy, due to more dry air over the mountain valleys.

But still expect some fog after midnight, burning off Monday morning.

Quiet weather expected over the next 24 hours as humberto spins off
the southeast coast and an upper anticyclone ridge builds to our
west, supporting sfc high pressure centered over the SRN central
appalachians. Expect to see another round of mtn valley fog early
Monday morning, with some of it locally dense. Low temps will
be mild. After the fog burns off in the mid-morning, the rest of
Monday will be fair and seasonally warm with high temps getting
back up to the lower 90s east of the mtns.

Short term Monday night through Wednesday
As of 130 pm edt Sunday: by Monday night TC humberto will still be
wobbling off the carolina coast as an upper ridge builds across the
eastern 2 3 of the conus. This will result in a hot start to the
short term forecast - MAX and min temps area expected to be at least
5 degrees above average Tuesday. Surface high pressure will be in
the process of wedging down the eastern appalachians Tuesday and
into Wednesday, and late Tuesday night a weak back door front (i
hesitate to even use "cold front" considering it's more of a just a
moisture gradient). Moisture with this boundary will be anemic at
best, though with the isentropic forcing of the developing wedge of
high pressure, we may be able to wring out some showers Tuesday
night and Wednesday. With a decent amount of cloud cover and the
advancing front expected Wednesday, highs will drop back down close
to normal.

Long term Wednesday night through Sunday
As of 145 pm edt Sunday: a very pleasant start to the extended
period is expected Wednesday night, with the weak back-door front
expected to have pushed through the area and much drier air
filtering in. A wedge of cool and dry high pressure will remain
along the eastern side of the southern appalachians, and with no
moisture return expected, Thursday and Friday should be dry. Upper
ridging will take back over the eastern CONUS over the weekend, with
temperatures expected to climb quickly back above average by the end
of the medium range.

Aviation 00z Monday through Friday
At kclt and elsewhere:VFR through the period, with the exception of
kavl. Dry high pressure continues to build in from the north, which
may limit fog a little from what we saw last night. Still expect
another round of mtn valley fog low stratus again after 06z tonight.

The latest guidance (especially the lamp) is a lot more optimistic
at kavl. So trended a little less pessimistic with the 00z taf. The
fog will slowly burn off again on Monday morning. May see some
stratus develop east of clt overnight, with a light E NE flow trying
to advect some of the moisture by daybreak Monday. Will introduce a
few025 mention to show the trend, but confidence on any low
restrictions is still low. Apart from that, light variable wind
overnight, and then light NE again on Monday. Could see a few
stratocu again with some heating Monday afternoon.

Outlook: fairly quiet weather is expected this week withVFR
prevailing. The mountain valleys will be the exception in the early
morning hours, with low stratus and fog a strong possibility around
daybreak each day. A back door cold front will push thru late
Tuesday, which may bring a chance of some more widespread stratus
for early Wednesday across the piedmont.

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.
