Update
For fire weather.

Synopsis
A positively tilted shortwave trough was analyzed across east
texas early this afternoon and extended northeast into the mid
south region. Toward the surface, a sprawling 1029mb high
pressure area was analyzed over interior southwest alabama just
west of evergreen. Satellite imagery continued to show clouds
over much of mississippi that were slowly drifting eastward and
were affecting our far western counties with cloud bases between
4kft and 6kft.

05

Short term
Today and tonight.

The shortwave trough over east texas will continue to move east
along the northern gulf of mexico this evening and into Saturday
while surface high pressure over southwest alabama will slide
further east tonight into south-central georgia.

A gradual increase in clouds are expected across our western
counties through this evening and into the overnight hours further
eastward into our central counties. As surface high pressure moves
eastward expect a light southerly flow to develop in the lower
levels late this afternoon and through the overnight hours.

The combination of gradual increasing clouds from west to east
along with weak warm air advection will help keep overnight lows
much warmer from previous nights with readings ranging from the
upper 20's northeast to near the freezing mark southwest. Adhered
to the cooler side of guidance overnight due to the continued
trend of temperatures averaging cooler at night warmer during the
day as has been observed the past few days. Recent snow cover
impacted surface temperatures across much of our area but that
effect has diminished substantially with snowmelt the past few
days. The higher than usual temperature swings could be attributed
to some influence by the persistently dry surface soil conditions
as depicted in recent drought monitor outlooks.

Dry conditions will persist through the short-term period as
despite increased amounts of moisture aloft the lower levels
remain too dry to support any precipitation.

05

Long term
Saturday through Thursday.

Clouds may increase on Saturday as a shortwave moves across the
region. Westerly flow around 850mb will be responsible for warm
advection and potential cloudiness, which may keep temperatures
from getting as warm as some models indicate. Our forecast is a
bit of a hedge between the cloudy and cooler NAM vs the warmer
ecmwf gfs. In the midst of a progressive pattern, the shortwave
should move eastward on Sunday and take the clouds along with it.

Meanwhile, a deep-layer ridge will shift eastward across the
region in advance of a strong plains trough. Temperatures on
Sunday afternoon could approach 70f in the south with mainly mid
60s elsewhere.

Height falls are expected on Monday with the approaching trough,
and moisture return should be sufficient for widespread shower
activity along a cold front. This system should move through
rather quickly with dry and relatively mild weather returning for
Tuesday through Thursday.

18z TAF discussion.

Vfr conditions will prevail through this forecast cycle.

Expect a few more clouds this afternoon and evening from the
southwest as upper level moisture levels increase but no impact to
categories for visibilities or ceilings. Low level winds from the
south will develop this afternoon and evening as surface high
pressure slides east of the area while aloft a shortwave trough
slides east along the northern gulf of mexico. Due to ample dry
air in the lower levels, no precipitation is expected through this
period.

05

Fire weather
Rh values will slowly increase through the weekend with values
remaining above critical levels. Light southerly winds are
forecast through the short term period and critical fire weather
conditions are not expected.

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.
