the region will move into a split-flow regime with the northern
branch jet moving across the northern plains and the southern branch
jet moving over the southeast and combining with the northern branch
jet over the east coast. Locally, this provides the area with
quiet and warm weather as shortwave ridging builds east. The
normal high for the kansas city area is about 40 degree right now.

Highs Saturday may be near 60 degrees. Gusty southwesterly winds
are also expected and this may result in an elevated fire danger
across the area as afternoon humidity values fall into the 30 to
40 percent range.

By Sunday morning a weak upper shortwave trough will lift northeast
into the region. This will bring us our best chance for
precipitation in the next week as widespread light rainfall spreads
northward throughout the forecast area Sunday morning. Rainfall
amounts look fairly light with this wave with about a quarter inch
of rain expected in our south. In northern missouri, only a few
hundredths of an inch of rain is expected. It's possible, though i
think unlikely, that some wintry mix develops in far northwestern
mo Sunday morning. It really will be a timing game between
overnight low temperatures and how quickly precipitation makes it
that far north. I think that it's more likely that temperatures
will be at or above freezing by the time precipitation starts and
should be just a cold rain in that part of the forecast area.

Through the middle of the week, upper level ridging will spread
across the area. This will result in continued warm and dry
conditions through Wednesday night. This may even persist into
Thursday but it will depend on the timing of a very strong cold
front that will plow through the region some time between Thursday
afternoon and Friday. A slower arrival of the front would result in
warmer temperatures Thursday and likely another dry day. After the
front passes through, Friday looks much cooler. Highs right now are
forecast to be in the low to mid 30s. But that will likely be colder
as timing in the front becomes clearer. It's very possible highs
next Friday won't make it out of the 20s. There remains a chance for
wintry weather to occur in the forecast area with this system. But
while models have decent agreement on the timing of the front, there
is much variability with the placement and amount of precipitation
as well as the track of the surface and upper level features. In
short, much can and will change.

Aviation (for the 18z tafs through 18z Saturday afternoon)
issued at 1120 am cst Fri dec 15 2017
vfr conditions are expected through the forecast with only high
level clouds moving across eastern ks and western mo. Westerly
winds this afternoon will decrease and back to the southwest
overnight. Strong winds aloft, between 1000 and 2000 feet agl,
will develop overnight. These winds will generally be from the
west. With surface winds from the southwest and a gradual increase
into these strong winds aloft, the threat of low level wind shear
looks low.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
