Synopsis
Issued at 333 am cdt Fri aug 23 2019
in contrast to nighttime periods of roughly the past week,
overnight convection has been fairly limited in the local area. A
stronger storm in south central nebraska appears to be being
enhanced by a modest weak upper wave under the mean upper ridge
between an upper trough over the northern rockies and another over
eastern canada. High cloud has been moving east to northeast
downstream of MCS activity in northwest kansas and northeast
oklahoma, and is making lower cloud coverage difficult to discern,
with the 0z top sounding showing a rather moist lower several
thousand feet and modest mid-level lapse rates.

Short term (today and tonight)
issued at 333 am cdt Fri aug 23 2019
expect the western kansas convection to struggle as it moves east
into weaker theta-e advection and a more stable environment, but
still have some concern for isolated afternoon convection to develop
locally today in weak ml CIN but also little in the way of forcing
for ascent. The weakening of the cap will depend on how much
insolation can develop, with confidence in low cloud trends not
high. Have kept slight chances in southern areas where the cap
looks to be weaker. Highs today should again be in the lower to
middle 80s. The rockies wave enters the high plains tonight and
should bring another round of convection to western and perhaps
central portions of the state. Instability aloft remains meager with
an easterly low-level flow continuing and have kept chances for
this activity reaching the local area small.

Long term (Saturday through Thursday)
issued at 333 am cdt Fri aug 23 2019
the upper wave continues slowly east Saturday into Sunday with
slowly increasing storm potential as precipitable water values
increase to around 1.8 inches and lapse rates steepen somewhat. With
the nocturnal low-level jet remaining less than 20 knots, convective
risks remain low however. The damp low to mid levels should keep
skies relatively cloudy through midday Sunday when the wave pushes
into missouri. A deepening upper trough passing through the northern
plains brings a cold front through the region Monday and Monday
night for more likely elevated convection potential. Model
differences remain in the character of the upper flow to the west
and northwest into the later portions of the week, with the more
zonal GFS bringing some potential for waa-induced elevated activity
in the mid-week. Have kept some mention of precipitation for much of
these periods but this could be overdone. Temperatures remain to be
somewhat below normal.

Aviation (for the 06z tafs through 06z Friday night)
issued at 1149 pm cdt Thu aug 22 2019
expect bkn ceilings with stratus of 3000 to 4000 feet through the
next 12 hours. If there are some breaks light fog may develop at
the terminals. Stratus ceilings may drop to 2500 feet at times
through the 14z fri.

Top 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.
