Synopsis
A backdoor cold front will move south across central nc this
afternoon and evening. Canadian high pressure will build down the
eastern seaboard into nc tonight through Friday bringing much cooler
and less humid conditions.

Near term today through tonight
As of 632 am Tuesday...

mostly sunny skies are expected this morning. The skies will
become partly cloudy as a cold front approaches from va this
afternoon in backdoor fashion, again.

The last couple of "backdoor" frontal passages have been dry with
little shower activity. We currently have some low chance pop for
the frontal passage this afternoon into the early evening. This is
most likely overdone. Essentially none of the guidance has much more
than a 20 percent chance pop for 0.01 at any one given spot. We plan
to carry that pop this afternoon n-e, then shifting s-w late
afternoon into the early evening. Models do agree in a post-frontal
period of stratocumulus overnight, with the highest signal in the
western piedmont. There may be some shower chances in the far
western piedmont, most likely west of the yadkin river due to the
upslope flow behind the front tonight. Highs today generally in the
mid 80s NE to around 90 south. Lows tonight 55-60 north and 60-65
south.

Short term Wednesday through Wednesday night
As of 128 am Tuesday...

the post-frontal stratocumulus stratus should be mostly confined to
the piedmont Wednesday morning, then skies are expected to become
partly to mostly sunny in all areas in the afternoon. A refreshing
ne breeze will advect in much drier and cooler air. Expect highs
only in the 70s, except a few lower 80s near the nc sc border area.

Then, mainly clear and cool Wednesday night. The most comfortable
night in recent memory. Lows in the 50s, with some upper 40s north-
central piedmont.

Long term Thursday through Monday
As of 355 am Tuesday...

surface high pressure will remain over the area late week into the
weekend, before slowly shifting offshore late weekend into early
next week. Meanwhile, mid upper level ridging will build over the
area late week and linger across the region during the weekend into
early next week. This will result in dry conditions with below
normal temps for late this week, with temps moderating to near to
slightly above normal for the weekend into early next week. Thus,
expect highs will generally be in the 70s for late week, with lows
in the the 50s. A few of the rural cold spots may see temps drop
into the upper 40s Friday mornings. Temps will moderate some this
weekend into early next week, with highs expected to climb back into
the 80s with lows around 60 lower to mid 60s.

Aviation 12z Tuesday through Saturday
As of 632 am Tuesday...

the fay TAF will be amd not sked until further notice. There has been
a failure of the ASOS with missing surface observational data.

GenerallyVFR conditions are forecast today. A backdoor front
will bring a 20 percent chance of an MVFR cig vsby shower this
afternoon and early evening; otherwise MVFR to ifr CIGS will develop
tonight. These CIGS will lift to MVFR thenVFR on Wednesday as the
dry and cool high pressure builds in from the north.

Outlook beyond 12z Wed VFR conditions expected Thursday
through Saturday.

Equipment
Unrelated to the helium shortage effecting the carolinas in nws
eastern region, an azimuth motor failure will result in missing
upper air observations at gso through 12z tue.

The fay ASOS has failed. Daily climate information will be estimated
until service is restored.

Rah watches warnings advisories
None.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
