Synopsis
Surface high pressure will remain over the region for the next
several days along with weak upper-level troughing. This will
support a slight chance of thunderstorms through Friday with
weak upper ridging strengthening Saturday and thunderstorm
chances diminishing.

Near term through tonight
Weak high pressure will remain over the area with upper level
troughing also across the region. Pwat values will be around 1.5
inches with instability moderate this afternoon and evening.

Issues surrounding convection will be westerly downsloping winds
working to dry the atmosphere and the lack of a strong trigger
mechanism or divergence aloft. As such will remain with slight
chance of thunderstorms from late morning through the evening
hours. With sunset and loss of heating potential for convection
will quickly diminish this evening with partly cloudy skies
overnight. Afternoon highs today will again be in low 90s with
lows tonight in the middle to upper 60s.

Short term Thursday through Friday night
Weak high pressure will remain over the forecast area with weak
troughing aloft. Tropical storm jose will remain southeast of
long island through the short term as hurricane maria moves
northwestward well off the southeast coast. This will result in
little change in the forecast area with moderate instability
and pwat values around 1.5 inches each day. With little support
aloft and lack of strong trigger mechanisms chances of
thunderstorms will remain low through Friday night. Best chance
of convection will be Friday as a series of short waves cross
the area. Temperatures through the short term will be in the
upper 80s to low 90s with overnight lows in the middle to upper
60s.

Long term Saturday through Tuesday
Few changes made through the long term as tropical storm jose
drifts off the new england coast and hurricane maria turns
northward. Hurricane maria is expected to remain well offshore
over the weekend then move northward away from the forecast area
early next week. Have remained with a dry forecast as hurricane
maria moves offshore of the area... However much will depend on
the exact track of maria and remaining moisture from jose. As
maria moves away from the region early next week upper level
ridging will move over the region and continue suppressing
convective potential. Temperatures through the long term will be
slightly above normal.

Aviation 15z Wednesday through Sunday
Vfr conditions expected outside of possible afternoon convection
and early morning fog Thursday.

An upper trough moving through the area will bring a slight
chance of afternoon showers and thunderstorms to the terminals
today. The chance is too low to include in current TAF issuance,
but will amend based on radar trends through the afternoon and
evening. The chance of showers and storms will diminish tonight
with the loss of heating. Models indicate potential for
fog stratus development late tonight into early Thursday
morning. Have continued to indicate MVFR ifr fog development at
fog prone ags ogb 09z through the end of the 24-hr TAF period.

Extended aviation outlook... Late night early morning
fog stratus possible each morning, mainly at ags and ogb.

Scattered diurnal convection possible Thursday and Friday.

Cae watches warnings advisories
Ga... None.

Sc... None.

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.
