00z TAF period begins withVFR conditions persisting through the
remainder of the evening. As high pressure settles over the
region, light and variable winds may lead to patchy MVFR fog
development at several TAF sites by early morning. Diurnal cu,
along with isolated showers and thunderstorm will be possible
during the afternoon hours. PrevailingVFR conditions are
expected at all terminals on Thursday. Winds will be out of the
south at around 5 to 10 knots.

short term forecast... Tonight through Friday...

it's a similar afternoon to what we've seen the past several days
with isolated showers and thunderstorms popping up across the
northern and western regions of the state. Likewise, this evening
we should see the precipitation decrease, with calm conditions
once again returning overnight.

The high pressure over the area will continue to build eastward
towards the east coast. Embedded disturbances should move through
the state along the periphery of the high pressure, and when coupled
with diurnal processes in the afternoon, will keep rain chances in
the forecast through Thursday. Additionally, an approaching cold
front will increase rain chances on Friday, especially in the late
morning and afternoon hours.

High temperatures will continue to be hot, with highs in the 90s.

However, on Friday we could see some cooler temperatures due to the
rainfall and cloud cover with the approaching front. Lows will
continue to be in the lower to mid 70s.

Extended term... Friday night thru Wednesday night...

models are starting to come around on a solution regarding the cold
front that will be approaching the state at the beginning of the
term. ECMWF and canadian models bring the front down about half way
into ar by Saturday night, and the GFS is a bit more aggressive,
bringing the front pretty much through the entire state.

For the moment I will go with a blend of the 3, which brings it
about 2 3 of the way thru the state, bringing significantly cooler
temperatures to those areas of the state. Some of the higher
elevations in the ozarks will probably struggle to make it out of
the 60's on Sunday.

The shortwave moving across the area, in conjunction with the front,
should fire off several rounds of thunderstorms through the first
half of the extended term. I went ahead and kept pops fairly high in
the initial period, and tapered them off toward the latter portions.

Lzk watches warnings advisories None.

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.
