What's New / NOTES
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.

The remnants of cindy will fill and lift quickly up the middle
atlantic coast this morning. A trailing pre-frontal trough will
linger over the ERN carolinas today, ahead of a cold front that will
cross our region tonight. The front will stall along the southeast
u.S. Coast through Sunday, then drift offshore Sun night.

Near term through tonight
As of 430 am Saturday...

amidst a diurnally-heated and continued very moist boundary layer
characterized by surface dewpoints mostly in the lower 70s, and
beneath modest wswly flow aloft between a sub-tropical ridge off the
southeast u.S coast and a broad trough centered over ERN canada and
the great lakes, a couple of pre-frontal troughs will provide a
focus for scattered convection by early this afternoon. While shear
profiles in the lowest 3 km will be weak, as the remnants of cindy
continue to rapidly weaken and lift up the NRN middle atlantic
coast, modestly strong flow above 3 km, on the order of about 40 kts
at 500 mb, will support effective bulk shear values around 35-40 kts
and also relatively long and straight hodographs. The magnitude and
character of the shear may yield a few (supercell) storm splits,
particularly across SRN and ERN nc where surface dewpoints in the
70s will be maximized and consequently favor pockets of moderate
instability. Both hail and damaging wind gusts would be favored from
this convective mode, despite weak mid level lapse rates. Otherwise,
multi-cell clusters capable of precipitation-loaded strong to
marginally severe wind gusts will be favored through the evening

Meanwhile, a cold front analyzed from ERN ny swwd through WRN va and
central tn and ky will settle slowly sewd, and across central nc
overnight. A chance of showers and storms will consequently linger,
and only slowly collapse sewd with the slow passage of the front and
following cooler and drier air-- overnight. The front is likely to
stall over the ERN sandhills and SRN and central coastal plain by
12z sun.

Given little change in airmass until the the fropa, temperatures
today are expected to climb into the 86 to 93 degree range, with
lows tonight in the middle 60s over the WRN piedmont to middle 70s
east of i-95.

Short term Sunday through Sunday night
As of 340 am edt Saturday...

dry weather is generally expected for a large portion of the area
for Sunday, outside of a lingering chance of some isolated
showers storms across our far southeastern portions of our forecast
area, near the stalled frontal zone to the south and east of the
forecast area. However, with the main surge of cooler area still to
the north and west of the area expect high temps on Sunday will
generally be in the mid to upper 80s, with even a few 90s in the far
s se. Dry weather will continue into Sunday night Monday morning,
with low temps generally in the lower to mid 60s.

Long term Monday through Friday
As of 410 am edt Saturday...

a reinforcing dry cold front will move through the area late
Monday Monday night, ushering in even cooler air into the region.

Highs Monday in advance of the front are expected to be in the 80s,
with highs on Tuesday generally in the upper 70s to lower 80s with
dewpoints in the 50s. Lows Tuesday morning area expected to be in
the 60-65 degree range. A more pronounced mid upper level
disturbance is expected to move through the area on Tuesday Tuesday
evening. The GFS and ECMWF still differ on if any showers storms
will develop across the area with its passage. Given the expected
dry airmass in place in advance of the feature, will limit pops to a
slight chances and only mention showers for Tuesday. Lows Tuesday
night are expected to generally be in the mid to upper 50s.

Surface high pressure will move across the area midweek and set up
shop offshore by late week. This will yield a warming trend back to
seasonal norms by the end of the week, with chances for mainly
diurnal convection slowly increasing by the end of the period
(though most if not all of the area will remain dry from Tuesday
late evening onward).

Aviation 12z Saturday through Wednesday
As of 745 am Saturday...

a narrow east to west-oriented band of 1500-3000 ft stratus centered
from near clt to rwi to ecg will gradually lift and disperse through
15z, but not before resulting in a chance of MVFR ceilings at all
but int gso for the next few hours. A few lingering wind gusts to
around 20 kts will also remain possible, also mainly east of int gso
this morning, as the remnants of cindy move rapidly up the NRN mid-
atlantic coast.

Scattered to numerous showers and storms with associated sub-vfr
conditions are expected to develop with diurnal heating after 17z,
and some may congeal into multi-cell clusters and spread east across
central nc late this afternoon and evening, all in advance of a cold
front that will move slowly southeastward across the forecast area
overnight. A chance of showers and storms will consequently linger
at ERN sites, and especially fay overnight, as the front stalls over
sern nc. There will be a chance of low stratus or fog over ERN nc,
including at fay, ahead of the front where low level moisture
humidity levels will remain high, late tonight-sun morning.

Outlook: generallyVFR conditions are expected through the middle of
next week, aside from a chance of a shower or storm on tue,
especially at ERN taf sites.

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.
