18z tafs - front will continue to lift north this afternoon
causing the rest of the winds across N ok to shift towards the se.

Showers and thunderstorms will be possible this afternoon into
early Friday with the highest chances across portions of northern
and western ok. However, chances are too low in several places for
a mention in TAF at this time. Strong, variable winds could be
possible near any thunderstorms. Lower ceilings are expected to
improve some this afternoon with MVFRVFR ceilings currently
expected tonight.

update...

a frontal boundary across northern portions of the fa is expected
to lift north. Rain clouds cooler air north of the front could
slow the northward progress today. Its movement northward is
already slower than many of the models. With this in mind, slowed
the front in the forecast. As moisture continues to advect
northward, showers storms are expected along and north of the
front. A cap over the warm sector will make it hard for anything
to develop today, except for maybe a few elevated showers storms
into early afternoon. However, if more sfc heating occurs than
currently forecasted or some sort of subtle lift, then a few
storms may develop, but for now that does not look likely.

Storms are expected to continue to develop west of the area
today tonight and move across western northern portions of the fa
this afternoon and tonight. Some of these storms could become
severe. Heavy rain flooding will also be a big concern in
western northwest portions of the fa, especially with potential
training storms. Flood watch remains in effect with no changes
made at this time.

a stationary front across northern oklahoma will become a warm
front later today, and move north into kansas. Low clouds will be
common through the day, with ceilings lowering this morning, then
rising slowly through the day. Thunderstorms are expected to form
late this morning, but will likely be fairly scattered. More
organized storms are expected later this afternoon through
overnight, mainly over western and northern oklahoma.

discussion...

additional moisture return is expected to continue through Thursday,
as the moisture boundary that promoted the severe weather on
Wednesday moves further northwest. Similar to yesterday, this
boundary will be the focal point of the formation of storms and
precipitation for Thursday afternoon into Friday morning. As the
dryline sets up in the texas panhandle, severe storms will develop
and move into western oklahoma. Based on the model soundings in the
afternoon, these severe storms are expected to be supercellular
with hazards that include large hail, damaging winds, and the
possibility of tornadoes in western and northwestern parts of
oklahoma.

One major concern as events unfold tomorrow evening into
Friday will be the potential for flooding and flash flooding as
multiple waves of storms train over the region in western and
northern oklahoma. A flood watch has been issued due to this
concern.

Due to upper-level ridging in the southeastern united states, the
next upper level cyclone moving through the southwest and the
rockies will be forced to move north through the high plains. This
results in the precipitation pattern and chances maintaining itself
into and throughout the weekend. The ridge is expected to constrain
the precipitation chances to north and western oklahoma, leaving
southeastern oklahoma and western north texas relatively dry. Day to
day movement of the surface moisture boundary will dictate where
precipitation will likely occur.

Early next week, another upper level cyclone will move through the
rockies and bring a chance of widespread precipitation across
oklahoma and western north texas. The strength and trajectory of the
low is uncertain as models diverge with both as the cyclone
approaches. Regardless, the consistent signal with the approaching
cyclone is precipitation chances next week with the possibility of
severe storms as well as possible flooding.

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.
