.PREV DISCUSSION... /issued 407 PM CDT Tue Jul 25 2017/

DISCUSSION...
The heat has returned in earnest today as temperatures surged into
the lower to mid 90s this afternoon. Fortunately, drier air aloft
was able to mix down significantly today which lowered dew points
and consequently resulted in heat index readings only a few
degrees warmer than ambient temperatures. However, this is not
expected to be the case over the next few days which is why heat
advisory headlines have already been posted for much of the region
on Wednesday with additional advisories possible later in the
week. The intense heat is being driven by the upper level ridge
which will be edging closer to the region through mid week so look
for mid and possibly upper 90s for highs through the end of the
week.

The silver lining in the forecast is the heat wave will be brief
as the upper ridge retreats back out west this weekend. This will
allow a cold front to drop south into the region Friday night into
early Saturday, aided by the long wave trough which will carve out
across much of the eastern U.S. through early next week. Scattered
showers and thunderstorms will accompany the front as it traverses
the region early in the weekend. Much more pleasant temperatures
will arrive behind the front for the weekend and through at least
the first half of next week as the upper level pattern keeps the
ridge well out west while the long wave trough remains in place
over the eastern half of the country.

Thanks for the coordination today FWD...TSA..LZK...LCH.
