Short term
The short term hi res and global models have continued the trend
since yesterday morning of slightly higher QPF late this afternoon
and evening. Indeed the precip band has held together well on
radar today as it has moved south across la and ms. A quick couple
reasons..The SW winds just above the arctic airmass at the
surface on the 18z sounding implies more effective isentropic lift
than a more westerly wind would. Very strong frontogenetic
forcing is supplying lift and the base of this accompanying 500 mb
shortwave is swinging through the region a little further south
than anticipated.

Despite this event still having overall very light precipitation,
there is increasing concern for a light glaze of ice this evening
across the new orleans metro, northshore, and coastal mississippi.

Model soundings support freezing rain or sleet across southern areas
early this evening, transitioning to just light snow on the back
side. It only takes a minimal amount of ice accumulation on roadways
to make travel hazardous. Primary concern is light ice and snow
accumulation on the bridges and elevated roadways region wide.

Temperatures are dropping quickly across northern areas due to
strong cold air advection. As the precip ends around midnight bitter
cold becomes primary concern, which will freeze up any remaining
moisture on roadways. By 12z Wednesday the 1045 mb surface high will
be centered over eastern oklahoma. This is very close to the gulf
coast for a true arctic high and as such we will be experiencing
near record cold temperatures. Low temperatures early Wednesday
morning will be in the upper teens across inland northern areas and
low 20s near the coast. Winds at this time will still be blowing
from the north at 10 to 15 mph and gusting to 25 mph south of the
tidal lakes. This will result in dangerous single digit wind chill
values. Temperatures will only recover into the mid 30s Wednesday
afternoon. Expect Wednesday night to Thursday morning to be just
about as cold with hard freeze conditions.

Long term
The gradual warm up into the weekend begins Friday as the surface
high pressure drifts east and the airmass finally modifies. Lows
Friday night will remain above freezing across all areas. Daytime
highs near 70 Saturday and Sunday. A 500 mb trough passes north of
the region late Sunday into Monday, which will bring another cold
front across the central gulf coast. This one looks much warmer with
rain and maybe some thunderstorms. Only a slightly cooler airmass
will build in behind with temperatures close to climatology.

Krautmann

Aviation
Main issue with terminals are going to be ifr to MVFR
cigs, MVFR vsbys, and winter precip. All terminals will see frozen
precip at some point from now till 9z. Btr and mcb are already
dealing with ip and sn and these should start to come to an end
between 0-3z tonight. As for the rest of the terminals -ra and -fzra
will start between 22 and 02z (beginning from west to east). Msy
will likely begin to see pl and sn mix in around 0-02z. Again
precip should begin to taper off from west to east around 4z
through 9z with the last gasps over coastal ms and gpt. Other
issue will be strong winds in the ll. Not expecting any
significant llws but winds could increase about 15-20kts in the
first 500-1k feet. Cab

Marine
Strong offshore winds are developing in the wake of the
strong arctic cold front which moved through this morning. Small
craft advisory conditions are developing across all of the coastal
waters. See no reason to make adjustment to this and will keep
headlines as is. Still looks like sustained winds should be in the
mid to upper portion of advisory criteria and could see a few gale
force gusts. Winds will remain elevated into Wednesday night before
easing on Thursday as strong high pressure builds into the region.

The high will shift to the east by the end of the week as the next
system begins to approach the area from the western gulf.

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.
