.DISCUSSION...
As expected have seen showers and a few thunderstorms develop
again today. On radar see multiple outflow boundaries pushing out
from these pulse storms. Given fairly limited instability and very
weak shear not expecting anything severe from these...and should
see them dissipate with loss of daytime heating this evening. Most
of these are just showers...very limited lightning. Like last
night cant rule out a couple of showers streaming in off the Gulf
overnight...but nothing more than that once these showers
dissipate this evening.

On Tuesday think will see fairly similar day as today. At upper
levels do have some weak ridging as heights rise and upper high
shifts s...but model soundings still show instability with only
weak mid level warming...so showers and few thunderstorms will be
scattered around once again especially afternoon and evening.

Wednesday and most of Thursday...upper high builds in with
ridging at surface and aloft. Model soundings suggest little if
any instability so think should be hot and humid...but generally
free of rain. Upper high flattens out for late Thursday and Friday
with soundings again showing instability. In addition models
suggest an upper disturbance will move in from the East on
southern flank of upper High. As a result will bring rain chances
back on for Friday...and possibly Thursday afternoon and evening
for coastal zones. Unsettled weather continues into the
weekend...basically summer like with hot humid conditions and
scattered showers and thunderstorms. 18
