Short term
Rainfall rates with thunderstorms yesterday were quite efficient
and there is no reason to think this will not be the case today as
well. Pw values are again around 2.5" today and storm motion will
be slow as well but at least somewhat pulsing. Storm total
rainfall amounts should not get out of hand but that is not going
to be the issue with any isolated areas that get the most
rainfall. It will be the rainfall rates that would cause the
issues. Some of these could drop around 3" hr with the heaviest
producers. Those thunderstorms capable of staying over any one
area for that full hour or more will see some flooding of low
lying and poor drainage areas. Basically, the totals fcast will be
for 2 to 4" with localized higher amounts possible. This should
be mainly in and adjacent to the slight risk of excessive rainfall
area that wpc has introduced. Severe wx variables are again not
impressive so rainfall should be the biggest issue outside marsh
areas. This could be much the same for Tuesday as well. But some
slightly drier air could keep precip numbers a bit lower for wed
and at least Thu but moisture will be back by Fri and hold through
the weekend.

Aviation
CurrentlyVFR conditions, but could see some MVFR ceilings between
about 11z and 15z. Convective development likely to be similar to or
greater than what occurred on Sunday. Tsra may need to be addressed
as soon as the next hour or two at khum and kgpt if coverage
increases on radar, and probably at kasd, kmsy and knew as early as
15z or so. If convection directly affects a terminal, likely to
produce MVFR ceilings, ifr visibilities and wind gusts to 30 knots.

Most convection should weaken or dissipate prior to 00z Monday. 35

Marine
Outside of the threat of thunderstorms affecting the waters mainly
during the late overnight and early morning hours, a benign weather
regime will remain in place through the end of the week with the
usual evening maxima in wind speeds. Seas of 2-4 feet at most can
be expected outside of thunderstorm effects. 35

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.
