Update
Morning update.

Synopsis
Goes-r mid level water vapor channel imagery along with global
models are in agreement in zonal flow aloft over the state this
morning while a shortwave trough was present extending from
central tennessee southwest over north mississippi and into north
louisiana along with eastern texas. Elevated moisture aloft was
increasing over the southern third of mississippi and into nearly
the southern half of alabama this this hour per water vapor
imagery. Skies remained clear across our forecast area but surface
obs in western and portions of central mississippi were observing
ceilings between 5kft and 6kft with this development sliding to
the northeast with time.

The 19 12z kbmx sounding features a stout dry layer from just off
of the surface to 500mb with a fairly dry environment present
further aloft. General unidirectional zonal flow was observed
through the vertical profile with winds gradually increasing with
height from about 20 kts around 900mb to about 30 kts around 650mb
and further increases to just over 50 kts around 320mb.

At the surface a 1029mb surface high was recently analyzed across
interior far southeast mississippi with generally light northwest
winds observed at a few sites in our county warning area.

Short term
Today and tonight.

Amplified flow aloft over the lower mississippi river valley
region will become further pronounced as the shortwave trough
slowly advances eastward. Upper level moisture will continue to
increase with some increase in clouds expected this afternoon and
evening. The lower levels will remain too dry to support any pop's
so a dry forecast will prevail through the short term period.

A southerly wind is expected to develop toward the end of the
short term period as the surface ridge slides to the east of the
state while. The combination of a southerly flow along with a few
clouds tonight will help keep temperatures in the 20's to the 30's
with warmest locations west and southwest overnight.

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.

12z TAF discussion.

Vfr tafs are forecasted for the next 24 hours. Surface ridge
overhead is in control of the weather pattern with little in the
way of clouds expected except for a few mid high clouds possibly
moving in late from the west with a weak upper shortwave. Winds
will be relatively light from the west southwest if any around the
ridge that will be slowly nudging to the east through tonight.

08

Fire weather
Rh values will fall to around 25 percent for a couple hours this
afternoon. However, winds will be light, thus critical fire
weather conditions are not expected. Moisture will increase over
the weekend.

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.
