Discussion
Through tonight: dry and mainly quiet conditions will prevail over
the next 24 hours. A low stratus deck is spreading across much of ms
this morning, and it will persist at least through the first half of
the day as cyclonic low level flow provides continued convergence.

Clouds should begin to break up by the afternoon and mixing
increases and flow becomes more divergent. With CAA persisting
through the day, high temps will be slightly below normal. Tonight,
with a mostly clear sky anticipated and winds slackening especially
in sheltered areas, radiational cooling should be strong enough to
allow temps to fall into the 30s across much of the area, including
some middle 30s in the cool valleys of north central ms. Dl
Wednesday through Monday: Wednesday morning is still expected to be
the coldest morning of the period with a warming trend and dry
weather lasting into Friday. A surface high will continue ridging
into the CWA from the northwest Wednesday morning while mid level
ridging shifts east over our region. This will result in a light
wind profile across our region and near full insolation of our dry
airmass. Afternoon highs will top out closer to normal, from the
upper 60s northwest to the mid 70s southeast. Another decent night
of radiational cooling is expected Wednesday night which will allow
temperatures to bottom out cooler than normal in the mid 40s at most
locations. Ridging surface and aloft will shift slowly east through
Friday but remain dominant over our CWA until late Friday afternoon
when a few showers will be possible in the west. Return flow will
increase Friday ahead of a low pressure system dropping over the
central plains. This will lead to pwats increasing back to near an
inch in the west to support the shower development. There will
remain low chances of rain in the west Friday night but, the
remainder of our CWA will remain dry until Saturday. Models continue
to differ with rain chances through the weekend and Monday for our
region. Split flow regime will continue with a northern stream
trough trying to drive a cold front through our CWA Saturday while a
closed low develops over the four corners region. Model consensus
suggests a cold front will move through our CWA Saturday afternoon
into Saturday evening with mostly anafrontal precipitation. The
precipitation looks to taper off Sunday morning followed by cooler
and drier conditions through Monday. The closed low is expected to
open up and weaken as it moves across our CWA Monday night. If the
gfs verifies, a continuation of wet weather Sunday night through
Monday would occur as a closed low moves across the the region.

Aviation
06z TAF discussion:
a deck of MVFR stratus clouds is moving across northeast ms this
early morning and will spread southward, impacting terminals
across central and east ms through the morning hours. Ceilings are
expected to lift with clouds clearing out by the afternoon hours.

Otherwise,VFR conditions will prevail through the TAF period. Nnw
winds will be gusty at times during the daytime hours today, with
a few gusts over 20 kt possible. Dl

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.
