Short term (through late Friday afternoon)
issued at 257 pm cdt Thu mar 21 2019
high pressure over the center part of the us will continue to move
south and draw in the last remnants of cold air behind a cold front
that passed through the region earlier this morning. Diurnal clouds
and gusty wind this afternoon will give way to clear skies and light
wind tonight. Temperatures will be at or above freezing overnight.

Friday will be mostly sunny and a tad warmer, although we are still
on the east side of the high pressure centered over southwest
missouri, some warming will occur but with a north wind, Friday will
only be a few degrees warmer than today.

Long term (Friday night through next Thursday)
issued at 257 pm cdt Thu mar 21 2019
next chance of precipitation will be on Saturday afternoon in our
far western cwa. Troughing just west of the rockies on Friday night
begins to deepen and nudge the ridge east. Ahead of this, strong
moisture return straight from the gulf of mexico will bring in
clouds and a chance of rain spreading west to east across missouri.

At this time rain looks scattered so the entire day will not be a
wash out.

By Sunday, the upper level low and associated surface low will have
moved to southeast nebraska, with strong warm air and moisture
advection ahead of it resulting in rain continuing into Sunday. Rain
will be more widespread by this time but amounts will be light. The
attendant cold front associated with the surface low, will pass
through our area overnight Sunday night into Monday morning. There
may be some lingering light rain into Monday, but most will remain
under cloudy skies.

Behind the cold front, cold air will lag a bit behind, allowing
temps to reach the low 50's on Monday, but Monday night into Tuesday
morning, cold air finds its way here, along with clearing skies will
result in temperatures at or around 5 degrees below freezing on
Tuesday morning. After that, high temps on Tuesday will rebound into
the 50's with 60's for highs on Wednesday.

a surface ridge over western mo will move southeastward, while
another surface high centered over the northern plains moves
eastward into the great lakes region Friday afternoon and
evening. Surface winds will be weak late tonight, mainly west-
northwesterly, then north-northwesterly Friday, and veering around
to a northeast direction Friday evening. Little if any cloudiness
is expected through the forecast period, except may be few
diurnal cumulus clouds late Friday morning and afternoon.

Specifics for kstl: a surface ridge over western mo will move

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
