What's New / NOTES
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.

20 12z issuance... PrimaryVFR conditions will prevail for the
next 24 hours, except for MVFR and brief ifr conditions in and
near scattered showers and thunderstorms from late morning through
the afternoon hours. Light winds expected to continue through the
period. 12 ds

Prev discussion issued 432 am cdt Wed sep 20 2017
near term now through Wednesday night ... The near zonal upper
flow becomes more amplified today as a series of shortwaves move
west to east across the southeast states. At the surface, a high
pressure ridge will continue to ridge from northeast to southwest
across the forecast area, with a small center of high pressure
over the gulf just to the south of the area today and tonight. The
position of this surface high will continue to result in a
general, light westerly low level flow over the area today and
tonight, with some diurnal effects as the flow will be more
northwesterly late night and early morning hours, then become more
southwesterly during the afternoon and early evening hours.

Pwat's today ranging from 1.60 inches northern zones to around
1.80 inches southern zones. This combined with daytime heating and
instability, the shortwave dynamics aloft, and sea breeze
interactions near the coast, will result in scattered showers and
a few thunderstorms across the region again today. Tonight, with
the slight northwesterly flow and loss of daytime heating and
instability, expect any lingering convection to end by early
evening. Some patchy light, late night fog will again be possible
tonight, especially for those areas that receive rainfall today.

Highs today ranging from the upper 80s to near 90 over interior
counties to the middle 80s near and along the coast. Lows tonight
expected to range from the lower 70s over most inland areas to the
mid 70s at the coast. 12 ds
short term Thursday through Friday night ... High amplitude mid
to upper ridge of high pressure that stretches from the eastern
and central gulf lakes region to the lower ms river valley and
north central gulf states will begin to shift west in response to
a broad upper low forming over the mid atlantic region west of
jose progged to shift southwest towards the southeast and
north central gulf states through Friday night. At the surface a
broad surface ridge of high pressure stretches from the northeast
conus to the southeast and north central gulf states is progged
to remain mostly intact or stationary through Fri night. With this
pattern increased moisture depth generally from the east and
southeast north of maria will continue to advect over the forecast
area through Friday night resulting in better coverage of showers
and thunderstorms for most locations, especially Fri and fri
night, with the best coverage occurring over northern and eastern
sections of the forecast area during the day on Fri then shifting
south over the lower parts of the forecast area including the
marine area Fri night. Model soundings support this reasoning
with pwats rebounding to 1.6 to 1.8 inches late Thu through fri
night with better lapse rates in the mid to upper levels of the
boundary layer also noted due to the cooler air aloft associated
with the upper low settling over the deep south. Better mid level
forcing will also be likley around the upper low as weak to
moderate impulses in the mid levels rotate around the center of
the low. As a result stronger thunderstorm development will be
possible Fri afternoon and early Fri night or mostly during max
heating with gusty straight line winds mostly 40 mph or
less... Frequent lightning and periods of very heavy rain being the
main concerns. Scattered showers and thunderstorms are also
expected on Thu forming mostly ahead and along a developing
seabreeze boundary shifting inland during the afternoon combined
with marginal instability and weak forcing aloft. As a result
thunderstorms will be more short lived and weaker in strength on
thu. Patchy early morning fog will also be possible each day in
the short term period. High temps will continue to be near
seasonal levels both Thu and Fri ranging from the upper 80s to
near 90 inland and the middle 80s near the immediate coast. Lows
both Thu and Fri nights will range from the upper 60s inland and
the lower 70s near the coast.

Long term Saturday through Tuesday ... The upper low over the
region will shift more to the west through the long term period
filling and become less organized Mon through tue. As a result
less coverage of showers and thunderstorms can be expected
beginning Sun continuing through tue. The threat for strong to
severe weather still remains low. Both high and low temperatures
will be been near seasonal levels with little change in the
humidity levels also expected. 32 ee
marine... High pressure centered over the marine area today
and tonight will break down by early Thursday, but a general ridge
of high pressure will continue to extend into the marine area from
the northeast through the remainder of the forecast period.

Initially light westerly winds today over the marine area will
become more light and variable tonight, before becoming primarily
light to moderate northeast to easterly Thursday through the end of
the period. Seas initially around 1 foot offshore with smooth
conditions on protected waters, increasing to 2, ocnly 3 feet,
offshore with a light chop on protected waters by the end of the
weekend. 12 ds

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.
