Short term
Today and tonight.

Looking at radar to our west this morning, it is difficult to stick
with zero pops for the day across the south. However, that is
exactly the plan for the day. Yes that disturbance, short wave is
out there, but models and flow keep the bulk of the moisture to our
south, while disrupting the coverage as the system works into the
drier airmass in place. The only impact to our forecast area will be
in the south, where cloud cover will increase late morning and then
slide east through the afternoon, before clearing tonight. So
temperatures will be a touch cooler south today with the added cloud
cover, but still most of the area will see upper 50s to low 60s for
the day. Clouds will decrease after sunset, only to increase in the
southwest close to sunrise as the next system approaches.

Long term
Friday through Thursday.

We've got a couple of key synoptic features that will drive our
weather for Friday. First, high pressure slides off the carolina
coast and sets up a cold air damming pattern. This will create a
backdoor cold front that moves east to west across central al, which
will influence our sensible weather early Friday morning through the
afternoon hours. Expect noticeably cooler temperatures for afternoon
highs, especially in eastern portions of our area, and mostly dry
conditions due to the drier easterly flow. Second, a deepening
trough through the central plains will push a cold front through the
ms river valley Friday afternoon, approaching central al by the
evening. This will increase rain chances from west to east beginning
after sunset Friday, becoming more widespread just before midnight
and into the overnight hours. By Saturday morning, the front should
be moving through our eastern counties, ending rain chances from
west to east before clearing out of central al completely by
Saturday afternoon. Instability remains minimal with this system, so
i don't expect much in the way of thunderstorms. Temperatures remain
in the upper 40s to low 50s for much of time Friday night into
Saturday morning, so expect a cold rain for any outdoor plans Friday
night.

Low level ridging builds in across the area Saturday afternoon
through Sunday morning ahead of another deepening trough dipping
into the upper plains. Expect a slight warming trend Saturday into
Sunday with partly cloudy skies. Winds shift more southerly by
Sunday as the upper level low becomes closed and lifts a surface low
through the mid ms valley and into midwestern states. A cold front
stretches southward from the surface low and will push through
central al Sunday evening and into the overnight hours. Moisture
return ahead of this system is slow, so i'm not expecting widespread
rain with the Sunday night frontal passage; therefore, i've kept
pops in the 30-40% range.

The cold front is south and east of our area by Monday morning as
the colder and drier air mass sinks in across central al. The upper
level low deepens and becomes generally stationary over the great
lakes region Monday through Wednesday, providing a persistent
northwesterly flow pattern across central al for most of next week.

This will lead to an extended period of below-average temperatures
with low temps and high temps running 5-10 degrees below normal for
this time of year.

06z TAF discussion.

Surface high pressure will keepVFR categories dominant this
period. The atmosphere is rather dry and any moisture present is
right at the surface or up high. Many locations are approaching
zero dew point depressions already late this evening, but surface
moisture is ground based. Therefore, some localized ground fog is
possible and may be enhanced near water bodies. Left a short
duration mention of 5sm br for tcl eet mgm toward daybreak.

Otherwise, just cirrus across the skies. Radar shows some echoes
back across louisiana, but the atmosphere is too dry here and the
weak disturbance rides south of here. Winds light northerly to
calm overnight becoming easterly at 5-6kts Thursday afternoon.

Fire weather
A drier airmass has settled over the region, influenced by
surface high pressure. No rain is forecast through Friday morning,
though relative humidity values will remain above critical
thresholds. Rain returns to the area Friday afternoon and evening.

There are no fire weather concerns at this time.

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.
