Discussion
A quasi-zonal flow remains over the region early this morning with
ridging to our west. At the surface, high pressure is centered to our
northwest, with a low-level northwest flow in place across the local
area. For today, the ridge aloft will build over the region, with
dry weather and temperatures a couple of degrees warmer. The ridge
will continue to shift west of the area through Wednesday as a
deepening trough moves into the central u.S. The surface reflection
associated with this feature will form along the northern gulf
coast southern plains area with a warm front, along with increasing
moisture spreading eastward, leading to showers and thunderstorms for
Wednesday afternoon across mainly the southern half of the forecast
area. Overall, Wednesday will see increasing clouds with temperatures
continuing to warm up by a couple of degrees.

For Wednesday night through Thursday, the surface low will move
through the southeast, with the warm front shifting north of the
area and the cold front passing late Thursday into Thursday night.

Widespread rainfall is likely, with some localized flooding
possible. In addition, we continue to see signals in the models
highlighting the possibility of some severe weather with the squall
line that comes through on Thursday. In particular, the NAM earlier
this afternoon was showing about an 80-knot low-level jet moving
into the region, and the 00z run really has not changed all that
much. The GFS does not show quite as strong of a jet, but still
shows increasing shear over the area, similar to the nam. We still
have some time to watch this, but models have been fairly consistent
over the past couple of days in showing the possibility of some
severe weather and, indeed, the storm prediction center is already
showing a 15 percent chance for severe storms for day 4 (Thursday).

Winds will shift to the west Thursday night into Friday, likely
increasing to gale force. Take this increase in winds plus the
increased wave action into account and we have a very good setup for
some coastal flooding. We will also likely keep clouds and some
shower activity around through Friday before high pressure and drier
air finally moves in for the weekend.

Aviation
Vfr conditions are expected through the forecast period. Light and
variable winds this morning will become west to northwest this
afternoon.

Marine
Light winds and seas will remain over the waters through Wednesday,
with no headlines expected. The next complex storm system will move
into the region Thursday, with showers and thunderstorms and overall
hazardous conditions. Winds are forecast to increase near gale force
Thursday night into Friday, with seas increasing up to around 14
feet or higher as well. Winds will start to diminish Saturday, and
will fall even more for Sunday, but waves will be slower to
decrease.

Fire weather
No fire weather concerns over the next several days as relative
humidity values will remain above critical levels. Some patchy,
shallow ground fog will be possible over the next few nights, mainly
over inland areas, but no widespread fog is anticipated.

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.
