.DISCUSSION...
Issued at 331 AM CDT Tue Jul 27 2021

Large scale pattern consisting of a dome of high pressure in control
across the central and western CONUS with decent moisture riding
over the top across the Pacific NW/northern Rockies. At the surface
an area of low pressure was centered over n-central SD. Meanwhile
stout environmental moisture was in place with dew points largely in
the mid 60s over the CWA.


Going forecast seems to be on track with the main focus the heat and
humidity thus no major changes planned. Along with daytime heating,
as dew points will crawl back into the low 70s, unpleasant sultry
conditions will ensue this afternoon. A repeat of excessive heat
and humidity is on tap Wednesday. Thus will maintain the heat
advisory for both days. On Thursday, a backdoor front associated
with a system dropping southward through the great lakes region
will push into the northern CWA by afternoon. This boundary is
progged to meander in the vicinity of the CWA all the way through
Saturday and be the focus for convective activity. Another benefit
will be a welcome reprieve from the heat and humidity.
