overall MVFR flight conditions will be seen, with patchy ifr with
heavier convection or fog development, while someVFR ceilings in
spots outside of rain and convection. The area of rain, showers and
thunderstorms will continue to gradually move across ar this
evening, affecting central and southeastern TAF sites. The
convection was ahead of a cold front which will also gradually move
east across ar this evening through tonight. Winds will be south at
5 to 15 mph with some gusts to around 20 mph ahead of the cold
front, while behind it, west to northwest 5 to 15 mph. Patchy low
level wind shear may be seen at times along the front as it moves
across ar. (59)

short term... Tonight through Sunday night
convection has contd to expand in coverage and intensity acrs WRN ar
this aftn. The activity has been evolving into a qlcs and expect it
to race acrs the rest of the fa thru early this evening. 24 20z
special sounding here at klzk conts to show robust instability south
of a warm fnt ovr far NRN ar. Low lvl SRH values of 460 m2 s2 (0-
1km) and 525 m2 s2 (0-3km). SBCAPE value has climbed to arnd 2200
j kg. One interesting point is the lack of cg lightning assocd with
this line of storms.

Damaging winds wl cont to the primary concern thru this evening.

However, as the activity works E of the hwy 67 i-30 corridor, would
not be surprised to see isolated spin-ups along and just ahead of
the line, possibly producing some brief tornadoes. The potential for
flash flooding also exists, even though the line of storms is moving
quite rapidly to the e. Thus, wl keep the flood watch in place thru
the late evening hrs.

Rain wl cont to end fm the E this evening, with just some lingering
chances ovr the far SE arnd midnight. The aforementioned cdfnt wl
stall to the S of ar on sun. A weak impulse tracking along the fnt
wl bring small rain chances to SE ar later Sun sun night. Otherwise,
a welcomed short period of dry wx is expected heading into early
next week.

Long term... Thursday through Monday
some timing differences continue to be evident between the long
range models and a blend of forecast solutions seems prudent this
afternoon.

Period initiates with high pressure over the region which will be
sliding off to the east during the day and be located over the ohio
valley by early Tuesday. Zonal flow at the start of the period will
turn more southwest with time as another upper low trough drops into
the desert southwest. In response to the increasing southwest flow,
moisture levels will begin to increase along with a corresponding
increase in temperatures.

A warm front is expected to move to the north into the state with
precipitation chances increasing once again. Low pressure expected
to develop on the front somewhere over the southern plains and move
off to the northeast dragging a cold front through the region.

Rain and thunderstorms are likely ahead of this front, with severe
weather a possibility once again, this time concentrated over the
southern half of the state. Additionally, heavy rain can not be
discounted once again. High pressure returns in the wake of this
system. Temperatures will average above normal through the period.

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.
