.SHORT TERM...(Tonight through Wednesday night)
Issued at 259 PM CDT Mon Jul 15 2019

The remnants of Barry will continue to move northeast tonight as the
subtropical low becomes absorbed in the upper flow Tuesday and
begins to depart the region to our east Tuesday night and Wednesday.
In the meantime, given the healthy vertical wind profiles, the
limited instability could yield some strong to possibly severe
storms, including a small chance of a weak tornado or two. The most
favorable time would be late this afternoon/evening and again
Tuesday (some increase in instability over today) per the SPC Day 1
and Day 2 outlooks of a Marginal Risk of severe thunderstorms.

Regarding the heavy rain and flooding threat, rainfall amounts have
been mostly in the 1 to 3 inch range (just thus far have been over 3
inches reported at Poplar Bluff ASOS) within the Flash Flood Watch
area. While there was a general lull in rainfall this afternoon,
given the saturated ground and forecast for more rainfall
- albeit fairly modest (1 to 1.75 inches) - will maintain the Flash
Flood Watch for now.

Winds should continue to decline as Barry weakens further, however,
we could still see some gusts Tuesday AOA 20 mph, mainly E of the
Mississippi River. Also, will decrease POPs from west to east
steadily tomorrow night and Wednesday, although we may see a slight
diurnal increase in convection with daytime heating Wednesday.

.LONG TERM (Thursday through Monday)...
Issued at 259 PM CDT Mon Jul 15 2019

The medium range models/ensemble means were in good agreement that
an expansive, capping mid/upper level ridge will be in place over
the southern half of the CONUS in the extended period, with active
weather limited to the northern CONUS. Southwesterly low level flow
most of the time will tend to maintain oppressive conditions for the
PAH forecast area, with heat indices reaching 105 degrees every
afternoon from Thu through the weekend, at least. Highs are expected
to be generally in the lower half of the 90s, and the moisture in
the air will tend to slow the overnight cooling process, yielding
lows (and dewpoints) generally in the middle 70s. Heat headlines
will be needed.

There are some model (deterministic, ensemble means) indications
that the southern mid/upper level ridge will be suppressed somewhat
east of the MS River by northern stream shortwave energy by the end
of the extended period. This may change the temp profile enough to
allow widely scattered showers and tstms to develop across parts of
the region as early as Sun afternoon, but the probability of pcpn
should be slightly greater on Mon with the possible approach of a
surface cold front.
