Discussion
Main forecast issue at this time appears to be the chances of
strong/severe convection to our NW actually making it to the
forecast area later tonight. Regional 88ds show scattered
supercells associated with advancing SRN plains shortwave and
increasing low level jetting across the red river valley... With a
few extending farther SW into cntl tx. Not seeing much in the
guidance that calls for this activity to actually make it to our
far nwrn zones prior to daybreak... But have updated pops to carry
slim chances to just outside our forecast area. Also threw in a
patchy fog mention over our far sern zones where winds will be a
little lighter overnight.

Update out shortly.

vfr and tempo MVFR conditions will continue across the area for
the next several hours before giving way to MVFR ceilings late
this evening. Southerly winds are expected to remain sustained
5-10 knots which should limit any fog development tonight. MVFR
conditions will continue through mid morning tomorrow before
giving way toVFR conditions.

wx map shows high pressure over the eastern gulf with low pressure
over the plains yielding southerly flow over the region. Goes-16
visible satellite imagery shows the scattered/broken layer of
clouds over most of the region. Temps this afternoon are near
80/lower 80s, likely to rise a couple more degrees the next 2
hours.

The forecast this week will continue above normal temperatures,
with 3 more disturbances to affect the region.

The next upper level disturbance affecting ok this afternoon will
move across the region Monday, with the best chance of showers
and thunderstorms across central louisiana and north of the
region. SPC has shifted marginal risk of severe thunderstorms
further north. For Tuesday, our region expected to remain precip
free.

By Wednesday and Thursday, the next upper level low will bring
increasing chances of showers and thunderstorms by late Wednesday
morning, with the best chances Wednesday night into Thursday
morning. Models are a bit quicker on ending the precipitation
Thursday afternoon. SPC has portions of the region in 15% chance
for severe thunderstorms, and as expected, will be finer tuned the
closer we get to the event.

Friday, our region expected to remain precip free. By Saturday,
the next disturbance is a little harder to pinpoint with
intensity/timing, as significant spread continues among the long
range guidance.

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.
