a very busy next 24 hours as four hazards are currently in effect
for this period. The first of these of these hazards is ongoing this
morning in the form of a dense fog advisory. This advisory is
covering areas south of the missouri river as warm air is advecting
into the area over a snowpack. Visibilities will occasionally
improve in areas of showers however visibilities will mainly be
reduced to a quarter mile or less in these locations. Further north,
fog will be lighter where areas of showers and isolated thunderstorms
are more likely to persist. There may be a break in shower this
morning however drizzle will persist before a second round of
showers and some scattered thunderstorms moves into the area late
this morning into the afternoon.

The rest of our hazards will occur this evening through tonight as
a strong surface low moves through northwest missouri into central
iowa. As it does it will drag a strong cold front through the area.

Very strong CAA behind the front will quickly usher in cooler
temperatures and cause precipitation to transition to sleet and over
to snow. Accumulations of 1 to 4 inches will be possible across far
northwestern missouri where a winter weather advisory is in place.

In addition to the snow, there will also, be very strong northwest
winds sustained between 25 to 35 mph with gusts to 45 mph. The
strong winds coupled with the snow will cause issues with visibility
due to blowing snow and as such a blizzard warning has be issued for
atchison county in missouri. Areas in the surrounding advisory may
need to be upgraded to a blizzard warning as they will experience
the strong winds as well however, at this time accumulations are
expected to be too minimal to cause visibility issues. Although only
few will see accumulating snow, the entire CWA will experience the
aforementioned strong winds and as such a wind advisory has been
issued for the entire cwa. Snow will exit the area overnight tonight
with winds subsiding below advisory criteria by sunrise on Sunday.

Sunday through Tuesday will look to be much more tranquil but still
cool with below normal temperatures. Continued CAA on the back side
of the storm system on Sunday will keep highs in the upper 20s to
the lower 40s south. High pressure will move into the area on Monday
providing copious sunshine but weak mixing. Consequently,
temperatures will remain cool with highs in the upper 20s north to
the upper 40s south. Tuesday there will be the slight chance for a
passing shot of light snow across northern missouri with highs again
in the upper 20s north to upper 40s south.

Wednesday and Thursday there will be chances for light snow as
models advertise quick moving disturbance moving through the region
on zonal flow aloft. The main limiting factor will be the lack of
moisture for these disturbances to work with. Friday, model
solutions are much different with the ec showing another weak
shortwave moving through the region on continued quasi-zonal flow
aloft while the GFS shows a much strong upper level trough moving
through the central plains. As such, forecast confidence is low
beyond Thursday.

Aviation (for the 18z tafs through 18z Sunday afternoon)
issued at 1157 am cst Sat feb 23 2019
the strong low pressure system approaching the area has brought
and will continue to bring a variety of concerns for this taf
period. Low visibilities are being observed across the area, but
they are trending to improve and should continue doing so,
slowly, throughout the afternoon and evening. The exception is
from about stj northwest and along the mo ia border. Strong winds
and falling snow will likely keep visibility low through much of
the overnight hours. Ceilings will fluctuate a little between
MVFR ifr lifr this evening but should improve after midnight
rather quickly from west to east. Scattered rain showers with
isolated to scattered storms should continue this afternoon. Then
this evening, the low pressure system will begin exiting the area.

Rain chances will continue, with a change over to snow in far nw
mo and a wintry mix in adjacent counties. The wintry mix is
expected to reach as far south as the kc metro tonight, before the
system completely exits the area. Once it does exit, conditions
should improve rapidly. The center of the surface low should move
northeast from south-central ks through stj up into southeastern
ia. This will shift winds to the northwest and also create very
windy conditions behind the cold front. Sustained northwest winds
between 20-25 kts with gusts up to 45 kts are expected. The peak
winds will move from west to east between 04z-12z. Winds should
gradually decrease throughout the day Sunday.

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.
