358 am cst Mon nov 20 2017

Short term
1020+mb surface high pressure is centered around the appalachian
mountains and extends south well into the gulf of mexico. It will
still be building into the CWA even into Tuesday mornings as it
shifts into the western atlantic ocean. Cold airmass within this
ridge will be realized with highs struggling to rise much above 60
degrees again today. Going into Tuesday morning, temperatures will
be slightly warming than this morning, but likely to fall decently
in SW ms and river drainages in sela and coastal ms. The fcst temps
are close to bias corrected MOS guidance for lows and blend of
models for highs.

Long term
Models show a broad trough moving into the middle of the country
from the canada us border to the gulf coast tonight. A split flow
pattern will begin developing by the Tuesday afternoon.

Amplification of both troughs will occur as a reinforcing cold front
passes across the CWA Tuesday night. This should occur before
moisture returns to the forecast area which means any rain chances
will just be for the coastal waters. This FROPA will take the little
warming that will occur on Tuesday and bring temps back down to a
good 5 to 10 degrees below normal for wed-fri.

The CWA will generally remain under troughing through the rest of
this week and through the weekend. This will be the case due to the
mid week trough's lack of progressiveness and a deep trough diving
out of canada into the eastern 1 4 of the CONUS this weekend. This
will keep rain chances out of the picture and temps at to slightly
below normal.

Meffer

Aviation
Mostly clear skies and excellent vsbys are expected through tonight,
except for some broken high level clouds late in the period.

Stronger north to northeast winds of 15 to 20 knots sustained at
knew and some 15 to 20 knot gusts at kmsy will start to ease by or
shortly after sunrise, then lighter winds will prevail the remainder
of the TAF forecast. 18

Marine
Surface high over ohio valley will retreat east today. Pressure
gradient will relax through Tuesday as the associated ridge axis
will remain north of the coastal waters. As a result, northeast
winds will ease and become more easterly today and Tuesday. A
surface low is expected to develop over the central gulf late
Tuesday and move east. Surface winds of coastal waters will become
northeast to north Tuesday night with wind speeds up to 15 to 20
knots.

A cold front will push through the area on Wednesday. The cold
frontal passage will increase north winds to small craft advisory
criteria Wednesday night through Thursday. High pressure will once
again build in over the area Friday and Saturday. 18

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.
