Discussion
Issued at 309 am cdt Wed oct 18 2017
very little change to the forecast this morning issuance as the
pattern continues to remain consistent. The warm fall weather
looks to remain in place through the remainder of the week. One
more day of northwest flow aloft before the upper pattern evolves
to southwesterly as ridging takes shape over the plains in advance
of highly amplified trough moving across the western conus. With
the northwest flow and upper ridging, expect dry weather to
persist through the end of the work week. H85 thermal axis slides
across the forecast area today in advance of a weak upper wave,
and helping yield afternoon temperatures a few degrees warmer than
yesterday. The warming trend should continue into Thursday as the
upper ridge axis moves overhead, with some locations flirting
near 80 degrees. For comparison, our average high today is 66
degrees, so readings will be a solid 10-15 degrees above normal
during the remainder of the work week.

A strong pressure gradient will develop across the plains states on
Friday with surface high pressure anchored over the appalachians and
a lee trough forming over the high plains. This will bring some
breezy conditions on Friday and Saturday, along with an increase in
moisture with dewpoints returning to the 60s by Saturday. Scattered
showers and isolated thunderstorms will be possible by Friday night
into Saturday morning as a 50 kt, h85 low-level jet and insentropic
ascent materialize over the forecast area. A cold front will sweep
through the area Saturday afternoon and evening, and with continued
moistening and increasing large scale ascent with the approach of
the upper trough, widespread showers and thunderstorms are likely.

While overall instability is projected to be relatively modest,
the strong wind fields would support organized convection, so will
need to closely monitor stability of the warm sector as event
nears.

The cold front will push through the CWA Saturday night, with
lingering post-frontal precipitation during the overnight hours.

Still, the progressive nature of the system should clear rain out
of the area before or shortly after sunrise Sunday, with clouds
clearing and a return of the Sun by midday Sunday. Cooler and
drier air will advect into the region, bringing back high
temperatures to seasonal averages in the 60s and dry weather for
early next week.

winds today will remain from the south Thursday, though speeds
will be lower and not and gusty.

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.
