Issued at 1043 am cdt Fri jun 23 2017
cold front has moved southeast through about halfway across the
cwa late this morning. The heaviest showers and isolated
thunderstorms associated with the remnants of cindy are just south
of the CWA over far southeast missouri into southern illinois.
Will keep with a chance of showers and a few thunderstorms ahead
of the front the rest of the morning into the early afternoon.
The chance will diminish over the southeast missouri and southwest
illinois counties by late afternoon as front pushes south of the
area. The clouds will also show some slow clearing as upper clouds
pushes off to the east and drier air moves in behind the cold
front. Going highs still look good for today.
Short term (through late tonight)
issued at 330 am cdt Fri jun 23 2017
cold front extending from east central ia southwestward to
northwestern mo to sink slowly to the southeast today. In the
meantime, tropical depression cindy, which is over central arkansas,
will lift northeastward into far southern portions of mo bootheel
late this morning, then track eastward along tn ky border. So
dealing with two areas of activity, showers and storms along cold
front that will continue to track southeast into northeast mo west
central il by 4-5 am timeframe and isolated scattered storms over
remainder of forecast area due to t.D. Cindy. Coverage of activity
from both systems hard to pin down, but best chances will be over
east central and southeast mo, as well as southern il through
midday, then taper off quickly during the afternoon hours as cold
front exits region. Because of clouds and precipitation, highs today
will be a bit below normal, in the low to mid 80s.
Dry and less humid air to make it's way into region behind cold
front as skies clear out. So lows tonight will be in the mid 50s to
Long term (Saturday through Thursday)

main focus thru the forecast period will be temps.
The cdfnt, currently approaching the CWA from the north, will be
south of the area by 12z sat. With a deep upper trof settling across
the eastern two-thirds of the u.S. With NW flow across the region,
expect mostly dry conditions with well below seasonal average temps.
A reinforcing cdfnt will bring another shot of cooler temps on sat.
However, this fnt will linger across SRN portions of the cwa. A S w
dropping into the region late Sun night into Mon will generate shra
along this fnt.
As the upper trof digs into the region, another reinforcing cdfnt
will drop thru the area. As the sfc ridge builds into the region,
expect Mon to be the coolest day of the forecast period. Temps shud
begin to rebound by tues as sfc winds become sly and the thermal
ridge begins to build into the area. However, still expecting below
seasonal average temps thru at least mid week.
As sly flow returns, the chance for tsra increases, mainly late in
the week. However, timing remains uncertain and have kept pops
fairly low attm.

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.
