message of the day: isolated to scattered storms are expected this
afternoon and evening with storms becoming more widespread
overnight. Isolated strong winds and hail are possible
today tonight, but heavy rain is the main concern. Up to 3 inches of
rain is expected for parts of the area with locally higher amounts
possible. Therefore, a flash flood watch has been issued from 7 pm
tonight until 10 am tomorrow along and south of the mo river.

The storm activity took a brief late this morning, but with some
clearing in the clouds, the advancing cold front, and effective
boundary leftover from this mornings convection, we are seeing new
storm development in our western counties and out in central ks.

This activity should be isolated to scattered in nature for the
afternoon and early evening. Isolated strong to severe storms are
possible anywhere across our area, with CAPE between 1500-2500
j kg and deep layer shear generally around 35 kts with some
pockets up to 45 kts. Winds up to 60 mph and hail up to 1 inch are
the main concerns. As we head into the overnight hours, severe
weather potential will decrease, as the flash flooding threat
increases. Pwats are expected to exceed 2 inches which is well
above normal for this time of year. Additionally, the west to east
oriented frontal boundary will stall near the ks mo ok ar border
as a southwest to northeast oriented LLJ strengthens. This will
enhance ongoing convection and increase coverage across the area.

The orientation of these features will promote training storms and
with fairly weak upper level flow, the system as a whole should
take its time moving south and east. As a result, excessive
rainfall is expected tonight, mainly along and south of the mo
river. Up to 3 inches of rain is expected with locally higher
amounts possible. As a result, a flash flood watch is in effect
from 7 pm tonight until 10 am tomorrow for counties southwest of a
line from atchison county ks to howard county mo. For the most
part, storms are expected to diminish exit the area in the late
morning as the LLJ weakens and high pressure starts moving in from
the north.

Storm chances will linger Thursday for those south of the mo river,
however most should be dry Thursday afternoon and evening with drier
air advecting in from the northeast. A somewhat messy upper level
pattern looks to take shape for the weekend, allowing for a few
chances for storms Friday and Saturday but that will be
counteracting the surface high pressure nosing into the area, so
right now it looks like most will by dry for the weekend.

Temperature- wise upper 70s to low 80s are forecast starting
tomorrow through the weekend. Not bad for the end of august.

starting to think the bulk of the heavy rain will move south of the
terminal tonight. Thunderstorm complex line in eastern kansas diving
se leads me to believe the better focus for evening overnight
thunderstorms will reside south of i-70. Certainly not implying a
dry forecast for tonight at kmci, but successive hi- res
simulated reflectivity also support better chances for heavy rain
well south of kmci. Have throttled back a bit on the
aggressiveness of the precipitation forecast, but kept a mention
of off-and-on showers through the next several hours. Used the
21z 22z hrrr to take a stab at cutting off precipitation
Thursday morning. Thereafter with cool and dry air moving in,
could see some low level stratus in the MVFR ifr domain for a few
hours before gradually clearing Thursday afternoon.

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.
