Short term tonight through Tuesday
A cold front currently analyzed across northwest arkansas into
southeast oklahoma and north central texas will continue moving
south and east into the four state region this evening into the
overnight hours. Temperatures have warmed well into the 70s
areawide this afternoon and with post frontal conditions expected
overnight, there should be sufficient mixing to allow for another
cool night tonight but perhaps not as cold as if we had ideal
radiational cooling conditions expected as has been the case the
last several nights. Still, undercut MOS temperatures a few
degrees in a few locations to account for the dry airmass in place
as guidance has been running too warm with overnight low
temperatures lately
stayed near to slightly warmer than MOS temperatures concerning
daytime highs on Tuesday as well. Northwest winds on Tuesday near 10
to 15 mph with some higher gusts in the morning from a tight
pressure gradient. 13

Long-term Tuesday night through Monday
Colder air behind Tuesday's cold front will push overnight lows back
into freezing territory for Wednesday morning. Winds will quickly
veer back SW during the day Wednesday and allow for a modest warm-up
as highs warm back into the lower to mid 60s. Another dry cold front
will arrive on Thursday with simply no moisture available with such
a brief period of return flow between fronts. Cooler temperatures on
Friday will be short-lived as southerly winds return in time for the
weekend. Increasing SW flow at the sfc and aloft by late Saturday
will present our best chance for rain during this forecast period.

This will be occurring ahead of another cold front shifting through
the plains, tapping into pacific moisture associated with an upper
disturbance near baja. SW flow will help usher in more of this mid
and upper level moisture ahead of the cold front with the best rain
chances across the SE half of the region but have at least included
slight chance pops even over our NW zones. Rain chances will wrap up
from the NW to SE with frontal passage on Sunday through the evening
hours. A dry and mild forecast will prevail behind the front for the
new work week with temperatures running near to just slightly above
normal. 19

aviation...

all is quiet on the aviation front this morning. Southwest winds
near 10kts or so today will eventually become northwesterly this
evening into the overnight hours in the wake of a frontal boundary
which will be moving into our airspace from the northwest. Post
frontal boundary winds will likely be near 6-12kts and beyond
12 15z, expect the possibility of some gusts upwards of 18kts or
so in a few locations. OtherwiseVFR conditional are expected to
continue through the next 24 hours. 13

It is not checked for accuracy either by anyone at L-36.com 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.
