Update
Updated for 06z aviation discussion

Aviation
06z TAF discussion:
vfr conditions will continue overnight as clear skies and light
northerly winds prevail. This should continue into tomorrow with
no aviation weather concerns expected. 28

Discussion
Evening update discussion:
subtle cold air advection continues this evening along the eastern
fringes of surface high pressure in the red river valley and
southern plains. Expect winds to be lighter from the northwest
than was the case last night, but generally there should be enough
gradient to prevent prime radiational cooling. Also, high clouds
(occasionally getting a little thick toward morning in the pine
belt) may also be a further slight hindrance to radiational
cooling. In the end, adjusted previous forecast to match current
cooler temperature trends but only very slightly lowered low
temperature expectations in most areas. Many areas north of the
highway 84 corridor will have a light freeze with confidence of a
few hours of sub freezing conditions increasing as you north. Bb
prior discussion below:

Tonight and Wednesday Surface high pressure ridging will continue
to prevail across the area this evening, with mainly partly cloudy
skies as some high clouds stream across the area. Low temperatures
will generally range from the low to mid 30s. Little will change on
Wednesday as the surface high continues to move eastward over the
region. Skies will be mostly sunny on Wednesday, with highs in
the mid to upper 50s and light winds. 15
Wednesday night through Monday: in this progressive pattern the
primary period of concern will be the weekend system as rain chances
return to the arklamiss. For late Wednesday upper ridging over the
rockies will bring dry northwest flow into the region. The upper
ridge axis will come over the mississippi valley on Thursday, this
will provide dry sensible weather to the region until Thursday
night. On Friday the upper flow will become west southwest as we get
some return gulf flow ahead of a developing upper trough pushing
into the plains. Moisture transport will bring in enough moisture
for some isolated showers across the far south and west during the
day. Rain chances will increase as we push into the weekend as
pwats increase to 1.3 inches. The models have some differences on
the amplitude of the upper trough. The euro and canadian were
deeper with this feature while the GFS had less amplitude. So with
the stronger solutions could get a surface low closer to the
coastal region for better rainfall amounts across our southern
counties of 1 to 2 inches. Will follow a blend of the two
solutions with the rains moving out by Sunday night as the cold
front exits the region. Will keep it all showers for now as
instability looks to be quite limited. High pressure will build in
from the west on Monday as the upper trough axis pushes to the
east.

As far temperatures are concern there is some potential for a light
freeze during the period with lows mainly in the 30s on the cooler
nights. Daily highs will be in the 50s and 60s. 17

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.
