337 pm cdt Sat jul 22 2017

Discussion Rather active day today with scattered to possibly
even numerous thunderstorms at times. Storm motion was very slow and
multiple boundary collisions led to a few areas seeing storms
persist for a little while leading to decent rainfall.

Ridge that was over the area and is breaking down will continue to
do so as a strong S W works southeast through the great lakes
region. This in combination with the mid level low overhead will
lead to even better rain chances tomorrow for much of the area.

Moisture will continue to be at a surplus with pws expected above 2
inches again.

We will still have elevated rain chances to start the work week. The
combination of lowered hghts and a weak bndry trying to slide into
the area could provide a focus for at least mon. However by Tue the
deeper moisture could shift just to the north and east and while mid
lvl temps begin to rise. This will lead to slightly lower rain
chances on Tue but by mid week and through the remainder of the work
week the ridge should build back in enough overhead to provide near
normal to possibly even slightly below normal rain chances. With
that look for the heat to return Tue and through fri.

Aviation Biggest issue with respect to the tafs will be
convection. Convection will likely continue to impact much of the
terminals over sela along with mcb but looking at radar trends
coastal ms should be fine through at least the remainder of the
afternoon. However a few storms could still impact gpt this evening.

Better chance for coastal ms could be during the early morning
hours. Outside of convection most terminals will deal withVFR
conditions.

Marine Still looks like high pressure will build in from the east
across the northern gulf while a weak front tries to drop into the
area early in the work week. This should lead to a slightly tighter
gradient with winds out of the southwest. Winds may become more
westerly by mid late next week. Showers and thunderstorms will once
again be more prevalent during the early morning hours and of course
winds and seas will likely be higher near storms.

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.
