230 pm edt Thu sep 19 2019

Discussion
A mid level ridge centered near tn al builds in across the eastern
u.S. Through Fri night as surface high pressure... Anchored on the
mid-atlantic coast... Stretches down into the gulf of mexico.

A drier northeasterly 1000-700 mb flow continues overnight
then becomes more easterly and more moist fri. Model pwat values
around 1.2 inches through tonight increase to 1.2 to 1.5 inches
fri with the higher values across the south. However these amounts
are sufficient for isolated to scattered showers and a few storms
to tracks in from the east this afternoon and again fri
afternoon.

Sat-thu: mid level ridging dominating the eastern states begins to
flatten late Sun then slide west as a canadian mid level trough over
the upper midwest sweeps across new england then offshore by midweek.

Surface high pressure on the mid-atlantic coast extends across the
gulf region as a trough of low pressure tracks west along the
greater antilles until mon..With a tight pressure gradient across
the area. Then the high weakens as tropical cyclonic jerry tracks
toward bermuda... See national hurricane center advisories and
forecasts for details and updates. The ridging aloft and drier air
will for the most part suppress significant rainfall. However the
trough passing by to the south will provide sufficient moisture
for limited diurnal showers and storms... Mainly confined to
southern locations.

Aviation
19 18z issuance.VFR. Sct to ocnl bkn sc plus ci late in the period.

Prevailing NE winds... Gusty til 03z and becoming gusty again aft
20 14z.

Marine
High pressure on the eastern sea board maintains a tight pressure
gradient across the waters with robust northeast or east winds... At
caution or advisory speeds and seas into the weekend.

Fire weather
High pressure will continue to filter in drier air for the next
couple of days although no low rh concerns are expected. A tight
pressure gradient will support robust 20 foot and transports
winds... Creating some high dispersion values.

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.
