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.

A warm and humid air mass remains in place across the mid-
atlantic states today on continued south flow. The next cold
front will arrive late tonight and exit the region by Saturday
morning. High pressure builds in for Saturday night through
early next week.
Near term until 8 pm this evening
Initial showers that developed early this morning are
dissipating quickly and the low stratus deck that has been
in place for most areas except along coastal areas of the
tidewater and NE nc is quickly dissipating too. As a result the
sun will be coming out and temperatures will quickly jump into
the upper 80s and continue up into the low 90s for most areas.
Ahead of the cold front, seeing lots of clear sky across WRN va
so warming should continue through the afternoon hours. With
dewpoints in the mid 70s to around 80 will see heat indices from
around 100 to 109 across the area. The highest values will be
across SE along the ches bay from the middle peninsula southward
into NE nc. So have issued a heat advisory for that area for the
rest of the afternoon.
Still looks like afternoon convection will form this afternoon
across WRN va and then head ese across the region. The 12z nam
is more enhanced with the convection so will need to monitor for
possible severe as CAPE is now forecast to between 3000 - 4000
j kg. The winds aloft are not extremely strong and the direction
shear is minimal. The mostly likely threat would be wind damage
Short term 8 pm this evening through Sunday
The front slowly pushes southeast early Saturday, and models
have once again trended a bit faster with the frontal passage,
allowing for a quicker end to showers Sat morning.
A strong shortwave trough sweeps across the mid-atlantic states
Saturday night, but it remains north of the area and with the
low level moisture gone, not anticipating much except some mid
level clouds. By Sunday, high pressure will be over the region
with dry and seasonable weather in place.
For temperatures, will continue to see near normal weather with
highs in the upper 80s to around 90 each day and lows in the low
to mid 70s each night except for Saturday night when the drier
air will allow temps to drop into the upper 60s to low 70s.
Long term Sunday night through Thursday
Sfc high pressure builds north of the area with stacked high
pressure residing off the southeast coast through Mon night.
A thermal trough develops in the lee of the appalachians for
tue Tue night, and then a cold front is expected to track
through the area on wed... Exiting the coast late Wed night.
Conditions will become increasingly more humid with each
passing day. Sfc features rather diffuse for mon, however
seabreeze boundaries with the presence of ample moisture will|
keep a slight chance for showers storms in the forecast...
primarily for the aftn early evening. Thunderstorm activity
expected to become widely scattered Tue as convection develops
invof lee trough. The frontal passage Wed wed night will
provide a better focus for more organized thunderstorms to
occur. Highs mon-wed generally upper 80s to lower 90s;
low-mid 80s beaches. Lows sun-tue nights generally 70-75f.
Lows Wed night mid-upper 60s NW to 70-75f se.
Aviation 16z Friday through Tuesday
Low stratus across terminals this morning with ifr MVFR CIGS at
ric sby phf orf. Expect stratus to slowly scour out through
13-14z, with an improvement toVFR at all sites by 15-16z.
A cold front approaches the region today, with showers and
thunderstorms developing and becoming more widespread by this
evening into Saturday morning. This will bring another chance
for sub-vfr conditions late in heavier showers, mainly
ric sby phf. Confident enough to throw showers and vicinity
thunder wording in at ric sby, but will keep thunder mention
out for now at orf phf.
Outlook:VFR conditions returns later Sat through the weekend as
high pressure builds back into the region. Some early morning
fog possible both Sunday and Monday mornings.
Latest sfc analysis shows weak high pressure offshore with a cold
front over the oh valley. This front will track east towards the mid
atlc today, with southerly flow increasing ahead of the front as the
pressure gradient increases. By this aftn eveng before the fropa
conditions will be close to SCA criteria over bay due to ~15 kt
sustained winds and northern cstl wtrs due to 4 ft seas. Not
confident enough that SCA conditions will occur to issue headlines
attm. The cold front drops into the wtrs tonight, with shras tstms
psbl and winds waves seas decreasing thereafter. For sat, with the
front weakening in the vicinity, expect winds AOB 10 kt by the aftn
with 1-2 ft waves over the bay and 2-3 ft seas over cstl wtrs.
Similar conditions into Sun with little change in the overall
pattern. Sub-sca conditions will continue into early next week with
weak sfc high pressure in the area.

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.
