Synopsis
Issued at 238 am edt Mon aug 26 2019
- showers and a few thunderstorms today
- areas of heavier rain tonight

Discussion (today through next Sunday)
issued at 238 am edt Mon aug 26 2019
moisture returns today with showers moving in late this morning and
becoming more numerous this afternoon. Thunderstorm coverage and
intensity will be limited by marginal instability but heavy rain
potential exists overnight with p-wats around 2 inches as the cold
frontal rain bands move through,
mbe vectors look less conducive for flooding than 24 hours ago as
storm motions should remain greater than 10 knots during this
event but some minor flooding will be possible if any training
develops.

The rain moves off to the east Tuesday afternoon but isolated showers
may return Wednesday as upper trough axis moves through and lapse
rates are steep enough for diurnal enhancement of CU development.

Lack of deep moisture should limit coverage across all but the
northern zones where soundings show better potential.

Then mostly fair and cool for Thursday but scattered showers
return Friday as sfc cold front pushes through.

Aviation (for the 06z tafs through 06z Monday night)
issued at 1246 am edt Mon aug 26 2019
a strong surge of moisture will move over the TAF sites later
today ahead of a sfc low. Showers are expected to develop during
the day and CIGS vsbys will take a turn toward ifr MVFR. Limited
instability will likely keep the threat of thunderstorms on the
low side. However, high precipitable water values will result in
potentially heavy downpours that could negatively impact braking
action.

Marine
Issued at 238 am edt Mon aug 26 2019
winds and waves will result in hazardous conditions for small
craft and for swimmers today through Tuesday afternoon. There
will also be some hazardous conditions on Wednesday along with
coastal beach erosion in strong onshore winds.

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.
