349 pm cst Mon dec 11 2017

Near term now through Tuesday Upper air analysis shows a
highly amplified pattern with an upper ridge over the western us
and downstream, long wave trof over the eastern half of the us.

West of the parent trof axis, a vigorous upper level impulse over
the upper mid-west and northern high plains drops rapidly
southeast over the mississippi river valley tonight. This feature
causes a cold front to sweep southward over the central gulf coast
by daybreak Tuesday. Deep layer moisture is very limited ahead of
the front, so expect front to make passage dry. Maybe a mix of
sun and clouds during the day Tuesday with the passage of the low
level h85 front. Outside of this, with the passage of the upper
trof axis to the east of the local area Tuesday, a reinforcing,
dry deep layer northwest flow sets up. May be a bit breezy as well
Tuesday, especially over the southern zones, where northwest
winds may gust to around 25 mph at times as the result of a strong
surface high building eastward out of texas. 10

Short term Tuesday night through Thursday night The deep
upper level trough will gradually shift eastward across the
eastern seaboard and adjacent western atlantic ocean Tuesday night
into Wednesday. Dry northwest flow aloft will continue across our
forecast area during this time frame, transitioning more zonal
Wednesday night into Thursday. A deep dry airmass will hold in
place over our area late Tuesday into Wednesday, resulting in
continue mostly clear and dry conditions. A cool surface ridge of
high pressure will continue to build eastward across the gulf of
mexico through Wednesday, keeping temperatures below normal across
our region into midweek. Another light freeze looks probable
across much of our interior again late Tuesday night and early
Wednesday morning, but temperatures should moderate back into the
mid to upper 50s by Wednesday afternoon.

Another shortwave trough will translate southeastward from the
northern plains to the mid-mississippi valley Thursday into
Thursday night. An associated cold front will sweep from northwest
to southeast across our area Thursday night. We trended temperatures
closer to the warmer MOS numbers vs. Blended guidance during the
day Thursday given low level west to southwest flow and low level
thermal ridging along the pre-frontal surface trough. Deep layer
moisture and ascent should be focused mainly near the southeastern
zones coastal areas and offshore ahead of the approaching front,
so will keep low pops confined to these areas Thursday night into
early Friday. 21

Long term Friday through Monday A deep dry northwest flow
aloft returns in the wake of the upper trough passage Friday, with
dry zonal flow by Saturday. The next upper trough and associated
front may bring another chance of rain Sunday into Sunday night,
but confidence on timing of and moisture availability ahead of
these features remains low. For now will keep pops in low end
chance range across the region (~30%). Temperatures will average
below normal Friday and Friday night as another surface ridge of
high pressure builds across our region. Temperatures should
moderate this weekend as the surface ridge pushes east and warmer
low level southerly flow returns. 21

Marine With the passage of the cold front late tonight, a
strengthening offshore flow brings a build in seas. Due to the
northerly fetch, the highest seas look to be confined to the 20 to
60 nautical mile zones thru Tuesday. Small craft advisories over
the open gulf waters remain unchanged on this package. Next in a
series of cold fronts makes passage early Friday morning bringing
a strengthening offshore flow and a build in seas yet again.

Similar to Tuesday, the offshore fetch causes the higher seas to
be more focused well offshore Friday and Friday night. 10

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
