Discussion... 
primarily showers with embedded storms along and east of the 
Interstate 45 corridor...or developing where the higher moisture 
resides. Southeastern Harris County convective outflow propagating 
northwestward over the County may provide better low level focus 
for more western-based late afternoon storms. If the region doesn't 
feel the downstream effects of the northern Texas short wave...then local 
mesoscale breezes...such as the sea (or bay) breeze...may also 
aid in providing that late day focus. With low 90f convective 
temperatures being met within a moist enough environment...any 
blossoming activity over the next 5 to 6 hours will likely occur 
along these residual outflow boundaries. 


Model ensemble in agreement of southwestern-based 500 mb ridging enveloping 
the state from tomorrow through the weekend. If this scenario does 
occur...then any rain/storm chances will be 30 percent or under 
and confined to only the local afternoon breeze behavior. Partially 
cloudy skies...only a degree or two variance with each of subsequent 
day's temperature extrema. The disclaimer will be for relatively cooler 
afternoon numbers over areas that experience late day (isolated) 
convection. As this ridge is forecast to overtake a good portion 
of the eastern u... weekend conditions should remain hot and 
dry. Modeling has backed off on the existence/strength of an slow 
approaching gom easterly wave. There is a hint of an inverted trough 
attempting to form underneath the ridge but...as of now...it appears 
that the ridge will win out. Nevertheless...with it being the 
first week of Summer...climatology standards for moisture values (pwats) 
peak out between 1.6 and 2.0 inches. Thus...hot and 'seasonably' 
humid late period conditions under an entrenched southerly flow. 
Fwiw...early day weak middle-level capping should erode each successive 
day as early PM temperatures exceed the lower 90s...allowing for the development 
of heat-of-the-day breeze-induced convection. 31

Marine... 
a diurnal pattern of slightly stronger winds overnight relaxing in the 
morning over the Gulf and generally lighter for the bays with the 
sea breeze circulation. Typical winds of 10-15 knots at night and 
near 10 knots during the day in the Gulf. 43
