Update
For 12z aviation.

Short term
Today and tonight.

Cold front with associated surface low is currently working through
central alabama. As of 3 am the surface low is beginning to slide in
the northwest and will continue to slide eastward through the
morning. Looks like the cold front is now right along the i-65
corridor and the rain associated with the front will continue to
push east through the morning. By sunrise the rain and the front
should be to our east, with juts the low pressure system and its
light rain left over in the northeast. Look for that to exit by 10
am at the latest. Clouds will eventually give way to sunshine in the
north this afternoon, with highs in the 50s north to 60s and
possibly a few 70s south. Clear skies tonight with another chilly
night night. Thinking that the winds stay up just enough tonight to
keep any areas or widespread frost from forming, but a few isolated,
protected areas may see some patchy frost. Lows will be in the 30s
and 40s.

Long term
Friday through Thursday.

A highly amplified synoptic pattern persists on Friday with a deep
trough over the east coast with a ridge in the central plains, and
another trough in the great basin. This will lead to mostly clear
skies for central al Friday and Saturday as the ridge slowly moves
eastward. The pattern begins for flatten slightly on Sunday morning
as the upper trough swings through the central plains and the ridge
moves off the east coast. This will shift our winds more southerly,
allowing for warm air advection across our area. High temperatures
on Sunday afternoon could be in the low to mid 70s for most of
central al, with some locations in the far south reaching the upper
70s.

A surface low lifts northeastward along the ohio river valley Sunday
evening through Monday as the main trough becomes more positively
tilted. A cold front is pushed through the region during the day on
Monday, but much of the synoptic forcing is well north of our area.

Instability is able to work in ahead of the front, so I have
continued to mention chance for thunderstorms in the forecast. At
this time, severe potential remains low due to the weaker forcing
and veered surface winds. The trough axis pushes through by Monday
evening night, decreasing rain chances for central al. Some guidance
still tries to bring another upper level impulse through the base of
the trough Tuesday morning, but even if this happens, moisture
return right behind the departing front is unlikely, so any
secondary front that pushes through should remain dry.

High pressure builds in Wednesday and Thursday, and a cold air
damming pattern sets up on the leeward side of the appalachians.

This will cause a backdoor cold front to move from east to west
across central al on Wednesday, which will help keep temperatures on
the milder side (highs in the mid to upper 60s, lows in the low
40s). We should remain dry through Thursday.

Aviation
12z TAF discussion.

A few lower MVFR CIGS may develop with or shortly after the
showers for a few hours this morning. Winds will increase as the
boundary moves through to the northwest and may be gusty during
the day. Skies clear and winds become light for Thursday evening.

Fire weather
Clearing skies today with a few drier days ahead. Min rhs don't
drop quite as bit as the past few days, but remain in the 30-40%
range. No fire weather concerns are expected at this time.

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.
