Center of mid level ridging currently situated over the lower Mississippi River Valley will expand east and northeast as we head into early next week. We'll still be under its influence thru most of the weekend, so anticipate weather to be about status quo to what we've seen the past few days. There are some higher PW's pooled southwest of the Matagorda Bay area as seen on the GOES Total PW product and is contributing to some iso/scattered precipitation activity there at the current time. We've also seen more late afternoon shra/thunderstorms between IAH-Huntsville the past two late afternoons than what NBM suggests so tweaked POPs up just a touch today & Sunday to mostly match what we've been seeing as of late.

Things are still looking progressively wetter as we head thru the work week when the ridging is far enough to our east/northeast and is less of a limiting factor for diurnally driven convection. Intermittent impulses rotating on the ridge periphery, higher moisture availability and daytime heating should all contribute to a fairly routine precipitation pattern this time of year...likely just more overall coverage on a daily basis. For the most part, I'd look for expanding shra/tstm coverage in the Gulf and near the coast during the overnight hours, then spreading inland during the day complements of heating. Look for breaks in the mid to late evening hours across most of the area...then repeat the above cycle for most of the work week if not longer. High temps should trend back down closer to normal with the clouds and precipitation around (and maybe slightly lower than average readings for days when rain starts earlier). 4 7

Those headed to the beach this weekend should be aware of moderate to maybe high risks of rip currents. We'll coordinate with the beach patrol in the mornings and may issue some rip statements if need be. Otherwise, look for Southeast winds in the 10 to 15 knot range and 3 to 5 foot seas for the next several days. Isolated showers and thunderstorms remain a daily possibility through the weekend followed by increasing rain chances next week. 47
