.DISCUSSION...
Upper lvl ridge which has brought mid 90 temps across the area,
will continue to do so as this ridge gradually expands eastward,
protected by zonal flow aloft further to the north across
midsection of country. Dewpoints not expect to mix out quite as
much today, and some temps may nudge into the upper 90s. Today may
see heat index values reach 105 across the area. The trend for
persistent temps to continue into Thursday, and even less dewpoint
mixing out expected, with dewpoints likely remaining in mid 70s
durg both the daytime and overnight hours. Therefore, have issued
heat advisory areawide for today through Thursday. Friday will see
more clouds from the north and possibly a few showers and storms
entering the picture Friday aftn, so will remain to be seen where
heat advisory criteria will be needed for southern portions of
area Friday aftn. As the upper ridge retreats westward with nw
flow aloft taking over, a weak cool front will continue to push
into the area on Sat and provide some relief to the mid and upper
90s for the past few days, and also possibly some welcome relief
in the form of convective rains./07/.
