Area Forecast Discussion

.DISCUSSION...
Wx today looks like a repeat of yesterday with highs 95-100. Heat
indices should peak in the 103-107 range, with the possibility of
slightly higher readings near the coast/bays for an hour or two 
as the seabreeze pushes in. Most locations will remain dry, but 
like the past few days, cannot rule out an isolated cell or two 
developing across southern parts of the area.

Convection currently extending thru the Plains into the Tx Panhandle
should trek e-ene thru the day and tonight. Think precip will 
remain north of the CWA thru tonight, but will keep an eye on any 
outflows, etc that could sneak in serve as a focus on Mon.

Upper trof will make its way into the Mississippi Valley late Mon
and it's associated diffuse & decaying frontal boundary will sag 
into parts of the region Tue. Moisture pooling ahead of the 
boundary combined w/ daytime heating and possibly seabreeze 
interaction/collisions should allow for some sct showers and 
thunderstorms to develop.

GFS has decided to join the previous ECMWF runs and start building
the upper level ridge back in from the west. So, unfortunately,
have pulled mentionable POPs out of the fcst for most of the
region Wed-Fri. Maybe some slightly higher possibilities next
weekend dependent on the eventual ridge positioning.  47

.MARINE... 
S/SW winds have picked up a bit across the coastal waters this morn- 
ing...and have issued SCE Caution flags for the offshore waters for 
today/tonight. This could be expanded to the nearshore waters later 
this morning/afternoon as the pressure gradient tightens further in 
response to the surface low deepening over Central TX. The strength- 
ening onshore flow will also help with increased shower development 
over the coastal waters this morning (and again Mon morning). Winds 
should be decreasing Mon night/Tues as a weak cold front moves into 
SE TX. Still not a lot of consensus on whether or not this boundary 
actually makes it into the nearshore waters at this time, but light 
and variable winds will likely prevail Tues night thru Weds night.
As high pressure (associated with this front) finally scoots off to 
the east...southerly winds are expected to return by Thurs and then 
slowly strengthen the rest of the week. 41

.AVIATION...
Will be keeping with the mention of brief MVFR VIS/CIGS and VCSH for 
a few of the TAF sites this morning given the trends of late. Slight-
ly stronger onshore winds/deeper moisture from the Gulf will help to 
increase SHRAs coverage along the coast this morning. While activity 
will be possible over inland locations this afternoon, confidence re-
mains low for the mention of VCSH/VCTS for sites north of HOU at the 
time. 41
