Thunderstorms have shifted east of northwest arkansas late this
evening with cold front. Additional showers will be possible
behind departing system late tonight into the day Thursday across
far NE ok/nw ar. MVFR conditions will be likely across these same
areas through mid/late afternoon.

instability has remained somewhat limited through the evening,
and as such, organized sustained updrafts have been hard to come
by. Over the past hour, scattered convection has developed ahead
of the cold front, which as of 930 pm had pushed a little east of
i49. Severe weather threat is very limited with this activity as
it shifts east of the forecast area over the next hour or so. Most
of the tornado watch was cleared earlier, and expect last
remaining counties to be removed by 11pm. Some wrap around showers
associated with upper low moving across eastern ks could affect
parts of northeast ok later tonight, with breezy w-sw winds
persisting through the night in many areas. Updated products have
already been sent.

concerning TAF sites ktul/krvs/kbvo/kmlc/kxna/kfyv/kfsm/krog.

MVFR ceilings will develop late tonight and early Thursday and
will persist through the day Thursday. A few patches of light
rain may occur Thursday in northeast oklahoma and northwest
arkansas, but the chances are too low at any one site to include
in the taf. West winds will occasionally gust over 20 knots during
the day Thursday.

surface low near the oklahoma/kansas border southwest of wichita
will move northeast overnight. Weak dryline/cold front is moving
across northeast oklahoma at this time, and the potential still
exists for a few strong to severe storms east of this boundary
over the next few hours. However, the greatest coverage of severe
storms will likely be east of our forecast area.

Thursday will be a cloudy, raw day, with the possibility of a few
showers across northeast oklahoma and northwest arkansas.

Temperatures will struggle to warm much at all during the day,
with some places likely not even reaching 50 degrees.

A rapid warmup begins Friday and continues Saturday ahead of the
next storm system that will result in another round of showers and
thunderstorms late Saturday into Monday. This system will take a
southerly track, so the severe weather risk in our area will be
quite low. Locally heavy rain will be possible however.

Another upper system will follow quickly on the heels of this one
Tuesday and Wednesday. Moisture return will be limited, but the
strength of the system dictates at least a mention of showers and
thunderstorms around Tuesday night of next week.

Stayed close to guidance temperatures the next couple days, with
the much colder NAM and ECMWF mos numbers preferred for high
temperatures Thursday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
