Marine Weather and Tides
Bayou Vista, LA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

discussion...

precipitation being observed on radar this morning is noticeably
more sparse in nature than it was this time yesterday. Still, with
deep tropical moisture in place (forecast pwat values of 2.2 to
2.3) the combination of the southward drifting tropical wave that
has brought the widespread rain over the past couple of days and
an eastward advancing upper trough over the central u.S. Will be
more than enough to initialize another day of numerous showers and
a few thunderstorms.

Went ahead and extended the flash flood watch until 00z this
evening for jefferson and orange counties and added southern
jasper and newton counties as well as calcasieu and western
cameron. Based this on the expected QPF totals through the day and
the rfc's flash flood guidance. The official forecast calls for 1
to 2 inches of rain across these areas, but with banding expected
to develop somewhere over this area again today, 3 to 4 inches
will certainly be possible in some spots. Meanwhile, taking the
previous rainfall into consideration, the rfc's flash flood
guidance is presently showing 6 hourly QPF thresholds of between
1 and 3 inches. As was mentioned in the watch product, the
addition of calcasieu parish was in order to include the western
half of the parish, including vinton, where significant rainfall
fell yesterday. 6 hourly QPF thresholds in this area are around 2
inches. The flash flood threat across the eastern half of the
parish is much lower with QPF thresholds in the 4+ inch range.

By tonight, the influence of systems over the region will shift
from the tropical wave drifting south into mexico to the
aforementioned upper trough deepening over the central u.S. The
end result will be about the same with this trough lifting the
continued deep layer moisture over the area to produce numerous
showers and thunderstorms again on Thursday. At this point it
appears that the axis of most widespread precipitation will shift
further east into southwest louisiana. The silver lining is that
as the trough slides east, it will take much of the mid and upper
level moisture with it bringing the precip to an abrupt end
Thursday evening.

The combination of drier air aloft and high pressure building in
across the eastern gulf will make for a dry end of the week and
weekend allowing some of the hardest hit areas to dry out. A more
typical summertime pattern will return by early next week with
scattered afternoon thunderstorms each day beginning Monday.
