Discussion
Regional radar imagery shows overnight convection has moved out
over the coastal waters with areas of light stratiform rain
remaining over southeast texas and southwest louisiana. These
areas of light rain are expected to diminish over the next few
hours. The cold pool from the overnight convection has introduced
some greater uncertainty to the forecast with regards to
additional precipitation developing later on today. Some of the
most recent cam guidance keeps much of the area dry through the
rest of the day with only widely scattered convection later this
afternoon. Meanwhile, global guidance continues to indicate more
widespread precipitation today albeit with lighter QPF amounts
than previous runs. Overall, the consensus is that showers and
thunderstorms will still develop later today but could be less
widespread than originally anticipated. Therefore, the pops for
today have been lowered slightly for today.

There is a greater model consensus for the development of
precipitation late tonight and through the day on Tuesday as the
stalled surface front continues to undergo frontolysis. Onshore
flow is expected to return late Tuesday into Wednesday and remain
in place for the rest of the week. A steady stream of moisture
from the gulf of mexico and caribbean sea will result in pwat
values ranging from +1 to +2 sigma over the region through the
weekend. Therefore, high rainfall chances will exist each day with
convection being driven by the seabreeze and mesoscale boundaries.

Current 7 day rainfall totals for the region look to be on
average 2-4 inches. However, given the prolonged period of above
normal moisture, higher local amounts will be possible.

Marine
Showers and thunderstorms are likely over the coastal waters today
and Tuesday with a stalled front nearby. Onshore flow will return
on Wednesday with increasing moisture resulting in chances for
showers and thunderstorms continuing into the weekend. The onshore
flow could also result in elevated seas, particularly over the
outer coastal waters, late Friday through Sunday.

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.
