348 pm cdt Fri sep 22 2017

Short term
A few showers and storms have developed this afternoon. These
storms should diminish over the next few hours as we lose daytime
heating. Expect more of the same for Saturday as an upper ridging
keeps convection at ease. We should expect seabreeze showers and
thunderstorms to develop Saturday. Temperatures will remain above
normal tomorrow. Going into Sunday, an upper level low is
expected to move into the area. This should increase vertical
motion in the atmosphere and showers and storm development and
coverage should be enhanced. Will maintain the 40 to 50 percent
pops for this timeframe the increase in cloud cover and
convection should allow temperatures to fall back to more normal
levels of late september in the middle to upper 80s.

Long term
On Monday expect the upper low to still have some influence over
the weather. Will continue to carry higher pops on Monday.

However, by Tuesday upper level ridging should effectively cap
the atmosphere through next Thursday. Strong convective
inhibition will be in place, and do not expect to see even much in
the way of cloud development. With a sinking airmass in place,
temperatures will easily climb well above normal in the lower 90s
both Tuesday and Wednesday afternoons. At night, the dry air in
place should allow temperatures to fall into the middle to upper
60s at most spots. The weak boundary layer winds and still
relatively high dewpoints in the low levels should allow for some
fog formation Tuesday through Thursday nights.

Aviation
ExpectVFR conditions to prevail through the period with generally
light winds. Isolated to scattered showers and storms may result
in brief restrictions at some terminals. Probability at any given
location is too low to include in the tafs at this time.

Marine
A large ridge of high pressure covering most of the eastern u.S. Is
expected to persist through early next week. A weak pressure
gradient with mostly light winds of 5 to 10 knots. The pressure
gradient increases some this weekend as a wave moves into the
area. Winds will increase into the 10 to 15 knot range late
Saturday into Sunday. Waves will increase to around 3 feet. High
pressure will then build back into the region next week with a
return to light winds and calmer seas.

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.
