345 pm cdt Fri aug 17 2018

Short term
Latest surface analysis showed a ridge of high pressure along the
florida georgia atlantic coast to northeast gulf to northwest
gulf. Surface dewpoint readings were 70 to 75 degrees across
louisiana and mississippi this afternoon. Wind were southerly 5 to
13 knots across the forecast area. Upper air analysis showed a
broad trough from the great lakes to lower mississippi valley. The
trough axis over the forecast area will allow surface heat to
ascent. Precipitable water values have increased up to 2.2 inches
this morning and these values will remain elevated through the
weekend. Storms that form will yield rainfall rates up to 2 inches
an hour. However, there is no sharp upper level trough axis and
no surface boundary to form widespread coverage at one time but
most areas will receive rain over the weekend. Will maintain
likely rain chances from late morning through the afternoon each
day through Monday. In addition, have lowered afternoon highs
around 90 through Monday.

Long term
Going into next mid week, a cold front is forecast move into the
lower mississippi valley late Tuesday into Wednesday. GFS and
ecmwf continue to show frontal passage Wednesday day period into
the forecast area. Have maintained morning lows around 70 across
the north half latter part of next week and decrease rain chances.

Aviation
Radar trends show that convection is becoming more scattered
compared to numerous showers and thunderstorms earlier today.

Vcts should cover most terminals as tempo seems too high for
the amount of storms out there. If a storm does pass overhead,
short term vlifr conditions with gusts to 25kts are possible.

Otherwise, MVFR toVFR conditions will prevail this evening and
overnight as showers and storms dissipate after sunset. Similar
weather pattern is likely tomorrow with TAF sites south of a kbtr
to khdc like seeing convection beginning to develop as early as
10z.

Meffer

Marine
Ridge of high pressure will remain anchored across the florida
peninsula to northwest gulf through early next week. As a result,
a prevailing onshore flow of 5 to 10 knots is expected across
most of the coastal waters through the period. The only exception
will be over the nearshore waters off the mississippi coast where
a seabreeze is expected to develop each day. This could induce
some stronger onshore winds of 10 to 15 knots for a few hours each
afternoon across the mississippi and chandeleur sounds.

Seas will range from 1 to 2 feet through the entire period across
all of the waters. Medium range models continue to show a brief
period of northerly winds late Wednesday after a cold frontal
passage, but no strong winds indicated with this frontal passage
outside of convection. 18

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.
