in the very near term, a few flurries are possible this afternoon
across northeast ks and northwest mo where scattered to broken
cumulus has developed at temperatures supportive of dendritic
growth. These clouds should dissipate diurnally around 00z, so
have only accounted for a few hours of isolated flurries in those
areas.

For tonight, some model differences in the timing of increasing
low-level moisture, but have trended toward the rap NAM solutions
and cleared out most of the cloud cover for tonight. This, coupled
with extremely cold 925 hpa temperatures and snow cover will allow
temperatures to drop below zero despite persistent 10-12 kt winds
overnight. This combination of very cold temperatures and winds
will bring wind chills into the -15 to -30 degree range, and have
upgraded the wind chill advisory to a warning in portions of
northwest mo where wind chills should drop to or below -25 for
several hours early Tuesday morning.

After Tuesday, a dramatic warm-up will begin as a longwave trough
moves into the western conus. Snow cover will begin to diminish in
sunshine Wednesday and should be nearly eliminated Thursday,
leaving no appreciable impact on the remainder of the warm-up for
Friday and Saturday. The warmest day of the period will be
Saturday when temperatures may rise into the 50s even in spite of
increasing cloud cover, when southerly flow is enhanced by an
approaching system.

The upper trough over the rockies will push out into the plains
Saturday and Sunday, pushing lee-side low pressure out of the
southern high plains and into the region by Sunday afternoon.

Precipitation with this system is likely as timing and track have
been (relatively) consistent, but precipitation type remains a bit
in question. Currently, the track of the surface and 850 hpa low
are a bit too far north for a classic wintry system in the
forecast area, but ensemble height standard deviations are highest
on the southern side of the low and could support a southward
shift as the system approaches. Will continue to monitor, but it
appears initial precipitation in the warm sector will be rain, and
will have to watch for the development location of deformation
zone snowfall when models settle on a more specific path.

vfr conditions expected until mid morning on Tuesday when a thin
low level layer of clouds moves into the area, which may lead to a
period of MVFR CIGS for a few hours Tuesday late morning into the
evening. Clouds should scatter out around sunset, going back to
vfr for the remainder of the TAF period.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
