What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Short term (through late Tuesday afternoon)
issued at 249 pm cst Mon jan 22 2018
the sfc occluded front continues to move east thru the CWA this
afternoon. Ahead of this front, temps have climbed into the upper
50s and 60s with clouds behind the front. The cold front is
currently just beginning to enter the WRN portions of mo. The sfc
low is expected to pull newd out of the region tonight into tues
morning. As it does, areas of precip will also move NE thru the
region.

This precip will be the focus for tonight. There is a fair amount of
uncertainty regarding precip coverage and intensity thru tonight. At
least some of the precip across central and WRN portions of mo is
convectively driven and is expected to diminish somewhat with
sunset. While the going forecast mentions showers, it is possible at
least a portion of this will be more drizzle than showers. Precip
will begin as rain as it enters the CWA this afternoon. As the cold
air filters into the region, this rain shud gradually mix with, then
change to snow. Have kept out mention of fzra fzdz as currently
expect precip to end as ice crystals are lost and due to forecast
soundings that are cold enuf to support cloud ice, albeit on the
warm side of that threshold. Still not expecting much in the way of
accumulation with light precip expected. What does accumulate shud
remain a half inch or less.

Clouds are expected to linger thru much of the day tues due to
cyclonic curvature across the region. These clouds are also expected
to be somewhat low, around 2000 ft or so. While some breaks are
possible, with CAA across the region, have trended twd the cooler
guidance.

Long term (Tuesday night through next Monday)
issued at 249 pm cst Mon jan 22 2018
a northwest flow shortwave will move through our area late Tuesday
night and Wednesday morning. Ahead of this feature there will be
mid level cloudiness, but it appears that low level moisture will be
too limited for any precipitation. Could not rule out a few
flurries, but will leave the forecast dry for now as the models have
none or very little spotty qpf. Temperatures Tuesday night through
Wednesday night will be close to seasonal normals for late january
with a surface ridge moving from the plains southeastward into the
gulf coast states. Warmer temperatures can be expected on Thursday
as an upper level ridge moves eastward into the central us, and
surface winds become southerly as the surface ridge shifts well
southeast of our region. Highs on Thursday should be around 15 to
20 degrees above normal. The chance of rain will return Friday
afternoon and night as an upper level trough and associated cold
front approaches, while low-mid level moisture increases over our
area. There were significant differences between the operational gfs
and ECMWF model for Friday night through the weekend. The ecmwf
model phases both the northern and southern stream, developing a
deep slow moving upper level trough, and keeping the chance of
precipitation going for parts of our forecast area until late
Saturday night. The GFS does not phase the northern and southern
stream energy, and hence is much weaker and more progressive with
the northern stream upper level trough, and weaker with the surface
reflection. For now will lean more toward the stronger and slower
solution of the ECMWF model, and keep the chance of precipitation
going until late Saturday night. It appears that the precipitation
type should be all liquid rain, with a small chance the rain could
change over to light snow just before ending Saturday night if the
precipitation duration lasts this long. Colder temperatures can be
expected Saturday night and Sunday after passage of the cold front,
albeit still a little above seasonal normals.

Aviation (for the 00z tafs through 00z Tuesday evening)
issued at 604 pm cst Mon jan 22 2018
wrap around sc continues to slide east through forecast area. Cigs
will lower to MVFR from west to east this evening and remain that
way through most of forecast period. With kuin closer to surface
low, will see CIGS dip down to ifr between 04z and 10z Tuesday,
before lifting back up to MVFR. Otherwise, main issue is the
winds and scattered precip. Gusty south winds to veer to the
southwest then west and eventually to the northwest as secondary
cold front moves through. Light rain will switch over to a mix of
rain and snow and possibly all snow before ending towards daybreak
on Tuesday.

Specifics for kstl:
wrap around sc continues to slide east through forecast area. Cigs
will lower to MVFR by 04z Tuesday, then back toVFR by Tuesday
afternoon. Otherwise, main issue is the winds and scattered
precip. Gusty southwest winds to veer to the west and eventually
to the northwest as secondary cold front moves through. Coverage
of precipitation will be widely scattered, so for now just have
vicinity shower mention between 04z and 10z Tuesday.

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.
