.DISCUSSION...(Today through Tuesday)
Issued at 341 AM CDT WED AUG 20 2014

Main weather story will be the developing heat wave across the
region as H50 ridge builds northward from the Gulf Coast region.
As this ridge expands and temps aloft warm, the daily chances for
convection will lower to isolated at best. Based on local criteria
of 100 to 105 heat indices for 4 or more consecutive days, will go
ahead and pop a heat advisory area wide with this package. Will
run it for this afternoon through Saturday afternoon. However,
will likely continue beyond Sat, as that blocking upper ridge will
be in no hurry to break down. Welcome to Summer`s first extended
heat wave.

Other than patchy late night/early morning MVFR/IFR fog, expect
high pressure to bring VFR conditions to all sites during this TAF
period.
