Short term
Line of robust thunderstorms moving through the area should begin
to weaken as they approach coastal mississippi this morning. The
high pop numbers are only for the morning hours just after
sunrise. Once the line of sh TS moves through, pop numbers will
drop to near zero. These short wave features in northwest flow
patterns are often stronger than what models normally suggest and
this mornings activity is no exception to that rule. Dry air and
suppresion should keep any of this from becoming severe but a few
of these could be strong with winds of 30mph or better as they
move through.

The next short wave feature moves through Friday. Eventhough these
thunderstorms will be on the low end of scattered over the
area, they could contain hail. Limited moisture and low vertical
extend should keep hail from become large enough for severe. But
the possibility that one or two of these could become severe will
exist. Any thunderstorm activity will begin to decay during the
late afternoon into early evening.

A back door front will move to the area before stalling Sunday and
Monday. Some of the dry air will filter from east to west but this
will be short lived as moisture return will begin on southeast
winds by Tuesday. This will occur ahead of the next cold front
that should move into the area by the end of the week.

A fast moving cold front is pushing through the area brining showers
and a few thunderstorms across the area, especially north of the i-
12 corridor. Ceilings are beginning to lower in many locations along
with winds of 25-30 knots as the stronger line passes through.

Behind the rain and the front, conditions will improve for this

A cold front will slide through the coastal waters this morning
increasing winds slightly. Extended exercise caution headlines until
early this afternoon (18z) and will let the day shift monitor for
any further extension that might be needed. Progressive upper level
pattern will bring yet another frontal boundary through the coastal
waters tomorrow. This will push winds back to 15 knots over the open
gulf waters for Friday evening through early Saturday. Surface high
pressure will track from west to east across the southeastern conus
this weekend. This will cause winds to rotate around from NW to se.

Onshore flow regime will settle in for the first half of next week.

Wind speeds will gradually increase due to tightening pressure

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
