the ongoing winter storm is beginning to wane as it quickly lifts
off to the northeast. Radar returns and surface observations show
light snowfall with periods of freezing drizzle along and north of a
line from mhk to stj to irk. South of that line, precipitation has
transitioned to a freezing drizzle with occasional snow flurries as
cloud ice has been lost due to arrival of a mid-level dry slot. The
remaining precipitation will gradually come to an end from southwest
to northeast during the mid to late morning hours, with most of the
forecast area free of wintry weather by lunchtime. That said,
hazardous travel from the existing snow and ice will continue
through the morning hours, especially on secondary roads and
untreated surfaces. Therefore will keep a winter weather advisory
for all areas through mid-morning to capture the remaining
precipitation and hazardous conditions.

The second half of today will be much more tranquil, and even the
sun could make an appearance by mid-afternoon across eastern kansas
and western missouri. With minimal cold air advection in the wake of
this system, highs are expected to be a few degrees warmer today,
even with snow cover, with most places reaching the 32-38 degree
range. The warming trend will continue Thursday into Saturday with
upper ridging building into the CONUS with highs pushing well into
the 40s - and perhaps some 50s by Saturday.

Model agreement continues to improve and tightly cluster on the
track of the weekend storm system - at 18z Saturday the gfs,
euro, and canadian have the h5 low within approximately 50 miles
of each other. The track continues to favor a rain scenario for
our area, with the potential for wrap around snowfall to clip
northwest missouri and northeast kansas as the system departs.

Cannot rule out minor snow accumulations in far NW mo.

Additionally, moisture and instability will be on the increase
ahead of the system, and a few thunderstorms are certainly
possible with the dynamics environment in place.

drizzle and freezing drizzle have moved north of the terminals
with MVFR CIGS beginning to scour out on the backside of the
system. Stiff south-southwesterly winds will decrease near sunset
becoming light and variable overnight as surface high pressure
builds into the region. Lowered visibilities at kstj will improve
through 19-20z as low cloud deck scours out.

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.
