Discussion See updated information for land areas and aviation
discussion below.

Update The severe weather threat has ended and tornado watch
427 has been cancelled. Zones and coastal products updated to
reflect changes. 10

Aviation
00z issuance...VFR MVFR ceilings over the area will gradually be
replaced overnight by lifr vlifr ceilings which spread into the
area from the west. Low ceilings prevail over the area through the
day on Tuesday. Showers with a few storms mainly over the western
half of the area currently move off to the east this evening, then
will be followed by rain spreading in from the west overnight.

Periods of rain are expected over the area Tuesday morning, then
diminish over the western portion of the area later on Tuesday. A
cold front currently moving through the area moves east of the
area overnight with a northerly wind prevailing in the wake of the
front through Tuesday. 29

Prev discussion issued 422 pm cst Mon nov 12 2018
near term now through Tuesday ... An inverted surface trough
currently bisects the forecast area from the southwest to
northeast. An associated cold front has moved east to the i-65
corridor, with temperatures in the mid 50s to lower 60s behind the
front. A warm front ahead of the surface trough has managed to
lift northward into extreme south central alabama by mid
afternoon, with temperatures currently in the upper 60s to mid 70s
residing in the warm sector. The tornado watch remains in effect
across our southern alabama zones and the western florida
panhandle until 7 pm, however updates to cancel portions of the
watch from west to east will likely occur before then.

The inverted surface trough and associated cold front will continue
to move east of the forecast area by late tonight, with temperatures
dropping into the mid 40s northwest zones to the mid 50s southeast
zones tonight. Brisk, cool northerly winds will occur throughout the
day Tuesday as high pressure builds in from the northwest with
temperatures remaining steady. Over-running in the post-frontal
stratiform rain will remain overnight and through much of Tuesday,
with widespread rainfall amounts ranging from 0.6 to 1.2 inches, and
localized higher amounts near two inches possible. 22
short term Tuesday night through Thursday night ... The global
spectral models are in excellent agreement on showing a sharp
positive tilt southern stream mid to upper level trof axis over
tx Tuesday night. Embedded in the trof axis, a nearly cutoff
upper low is to be positioned over the river valley of tx ok.

This favors a slow eastward translation of this weather feature thru
Wednesday. This maintains a potentially messy weather pattern
into the middle of the week as a series of mid level impulses
embedded in the southwest flow aloft will continue to make passage
and maintain upper level contribution to ascent over the area. At
same time, a steady stream of moisture will continue to flow from
the gulf, up across the southeast us. At the surface, strong cold
front will have surged into the southeast gulf Tuesday night with
a large dome of cold high pressure expanding in from the
northwest. Going into the day Wednesday, a wave of surface frontal
low pressure forms over the eastern gulf front and will be
lifting off to the northeast over the fl peninsula. To the
northwest of the poleward advancing frontal low, a surface trof
becomes aligned over alabama. Considering the high level flow,
moisture, and some enhancement in the surface focus with trof
near- by, will maintain an elevated chance of seeing stratiform
chilly rains. Highest over the southeast half of the local area
thru Wednesday evening.

The southern stream storm system, ejecting over the lower ms
river valley Thursday, begins to phase with the northern stream
and begins to deamplify and lift out and quickly off to the
northeast Thursday night. Drier air will begin to move in from the
west and rain chances decrease from west to east by Thursday.

Keep the coats handy as cold conditions continue into the day
Wednesday with cloud cover and rain making it raw. Highs looking
to only make it into the mid to upper 40s northwest of i-65 and
lower to mid 50s southeast of the interstate. May see freezing
temperatures over portions of the interior Wednesday night.

Continued cool on Thursday and cold Thursday night. 10
long term Friday through Monday ... Surface high pressure will be
the dominant weather feature during the medium range and brings
rain-free weather. Temperatures to remain well below seasonal
normals during the medium range. 10
marine... A strong cold front will move through the marine area
tonight, followed by a moderate to strong offshore flow through
Thursday. A light to moderate northerly wind will follow through the
remainder of the week. 22

It is not checked for accuracy either by anyone at L-36.com 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.
