area forecast discussion

416 am cdt Sat may 25 2019

Short term
No appreciable changes in the ongoing fcast this morning. Stacked
ridging will give way a bit as the front currently located over
the central CONUS gets a bit of a push to make its way to near our
area by mid to late next week, obviously a very slow process. This
will weaken the ridge but there looks to be enough mid layer
subsidence provided by the high to keep thunderstorm numbers
lower than what we currently see with this front. As we get into
the middle of next week there will be a better idea of the type of
activity that will be associated with this front. Eventhough the
front stalls over northern la ms, there could be just enough
destabilizing effects to get enough cloud cover and sh TS to
develop farther south of the front. At the moment, this looks like
a simple isolated downburst type pattern with the dry air layers
provided by the ridging that is still holding just east and
southeast of the area. This is still a ways out especially for
fcasting even isolated to scattered thunderstorms.

Aviation
As has been the case the last few nights, brief flight restrictions
can be expected this morning at several terminals. So far this
morning, the restrictions have been at khum and kasd. Kasd has been
down to ifr, with khum at MVFR. Can't rule out other locations
seeing similar conditions. Any restrictions should improve toVFR
around 14z. The remainder of the daytime hours will beVFR. Again
overnight, primarily in the 07-14z Sunday window, brief flight
restrictions will again be possible. 35

Marine
Upper ridging over the southeastern us will keep a persistent wind
flow in the east to south quadrant through the forecast period. Do
not expect winds to get much above 15 knots through the forecast
period, and do not anticipate any lengthy periods of exercise
caution conditions, if they occur at all. 35

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.
