Sounding discussion
The upper air release this evening was routine with no problems
encountered. The 00z sounding indicated that the atmosphere was
dry and stable with a precipitable water value of 0.77 inch. A
strong inversion was present just above 800 mb. North to northwest
winds prevailed in the lowest levels with west-northwest to west
winds throughout the remainder of the sounding. 11

latest surface analysis showed a 1012mb low over western
tennessee with an occluded cold front to north georgia to florida
panhandle. Upper air analysis revealed a low on top of the
surface low and trough from montana to wyoming. West to northwest
winds were present across the forecast area this afternoon. With
the close proximity of the upper level low, wrap around moisture
and clouds were spreading across our northern zones, southwest
mississippi and northern parts of the florida parishes.


vertically stacked system will slowly progress east to the eastern
seaboard by Wednesday morning. While technically we had a cold
frontal passage, this feature did not usher in very dry air.

Surface pressure gradient will continue to relax tonight through
Wednesday. Temperatures overnight will fall and atmosphere at the
surface will become saturated tonight and Tuesday night, mainly
across the northern zones. Therefore, we maintain the patchy fog
wording across northern zones tonight and Tuesday night. Cloud
cover may hamper temperatures from falling in spots tonight. Fog
coverage is expected to develop earlier and slightly more
expansive across the north zones Tuesday night into Wednesday

The trough approaching the northern plains is expected to dive
southeast through this week and reach the lower mississippi valley
late Wednesday into Thursday. Precipitable water values will
increase up to 1.4 inches ahead of the trough Wednesday night into
Thursday. Southeast flow does not really develop ahead of the
trough and associated front and only marginal instability will be
in play. Will insert isolated thunder due to the frontal focus
late Wednesday night and Thursday. A secondary wave is expected
Friday afternoon and evening. Precipitable water values are
expected to fall to a half inch early Friday across the forecast
area and increase up to an inch along this second wave. Will
maintain isolated showers as no instability will be available. A
pleasant dry weekend is expected with temperatures below normals.


the pressure gradient has weakened slight more than expected.

Surface observations as a general do not support an exercise caution
headline. Thinking winds will more consistently fall in the 10 to 15
knot range rather than above that. Tuesday and Wednesday will see a
similar offshore wind regime as high pressure builds in from the
north. Actual wind direction will vary from northwest to northeast
as the ridge to the north slides east. A reinforcing front will
slide through Wednesday night as a weak upper trough tracks across
the southeast. A surge of drier air behind this front could push
winds back to around 15 knots Thursday morning. Winds should quickly
drop back to around 10 knots by the afternoon, and remain out of the
northwest around this speed through Friday. A third frontal passage
could once again push winds back to 15 to 20 knots over the open
gulf waters for Friday night and early Saturday.


visible satellite shows wide swath of cumulus clouds wrapping around
a low pressure centered near the mo ar tn ky intersection.

These clouds are bringing ceilings down into the MVFR range. These
conditions, borderingVFR and MVFR will persist through much of the
taf period until the low lifts north and east tonight.

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.
