Update
For 12z aviation.

Short term
Today and tonight.

The coldest air mass of the season has settled over alabama.

Temperatures have fallen below freezing across much of central
alabama this morning, with some locations across the northwest
counties reporting middle 20s. A surface high over the southeast
states will slide east of alabama this afternoon and low level winds
will become southeast. This will produce slightly warmer afternoon
temperatures today with highs in the upper 50s to lower 60s.

Increasing southerly flow overnight will also result in much warmer
temperatures with most locations staying above the freezing mark.

Cirrus will stream across the area today, with an increase in lower
clouds across much of georgia and far eastern alabama after
midnight.

Long term
Tuesday through Monday.

Overall, the synoptic pattern doesn't chance much through the
extended forecast. We're under a highly amplified pattern with
ridging across the western us and a trough over the eastern us. On
Tuesday, our winds do shift to a more southerly flow as the surface
high pressure is pushed out into the atlantic. This could allow for
some very modest moisture return during the day ahead of a weak
shortwave impulse that moves through the base of the deeper trough
over the gulf states. As this shortwave moves through, I can't rule
out some light shower activity, so have kept mention for a slight
chance to chance pops generally south and east of the i-85 corridor
Tuesday and Tuesday night. At the very least, expect increased
cloud cover. The rest of central al should remain dry. By
Wednesday, the axis of the main trough has moved over alabama,
which will mark a shift in the winds back to a northerly flow for
the rest of the week as the trough axis slides east of our area.

So, even with models coming into better agreement with another
shortwave moving through the base of the trough Wednesday into
Thursday, it looks like central al will be cut-off from any
meaningful moisture return, limiting our chances of rainfall. A
weak cold front associated with the shortwave could lead to
slightly below average temperatures for thanksgiving. Central al
remains cut-off from any moisture return through the weekend, so i
have removed any pops in the forecast Wednesday through Monday.

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.
