Hey, I hate to bother y'all but I'll be traveling from SW of Houston on Monday (Wharton) I am kind of trying to decifer your data for tomorrow and Monday to travel to Patterson, La. It doesn't look like a huge window to get home. (The ONLY reason I'm asking is because I have my mom and her cousin with me and I'm about to leave them on the side of a higheay!) :-) Cat 5 relatives!!

Day 2 has an enhanced for southern and central Alabama, Florida panhandle, and central and northern Georgia. I'm on the very southwest edge of that area. Could be a worse forecast I guess. Hoping not anyway.
...SUMMARY... Numerous severe thunderstorms are forecast from parts of Texas eastward into the lower Mississippi Valley today and into tonight. A concentrated area of significant wind damage is likely near and north of the I-20 corridor in east Texas and Louisiana. The risk for tornadoes, a few of which may be strong/damaging, will probably maximize near and south of I-20 in Texas and Louisiana, along with the threat for hail.
...Synopsis... A closed mid-level low will evolve into an open wave and move from northern Mexico/Far West TX eastward to the ArkLaTex by early Monday morning. A broad area of surface low pressure over the Rio Grande Valley will consolidate and develop northeast across central TX during the day and be near the OK/AR border at the end of the period. A maritime warm front will advance northward across the northwest Gulf Coast region during the day as a cold front accelerates eastward across central TX during the afternoon and into LA during the overnight.
...Central TX eastward into the lower MS Valley... A multi-hazard, likely multi-scenario forecast with intrinsic complexity/uncertainty is seemingly evident for today into tonight. Late Saturday evening surface analysis and radar imagery show rich low-level moisture over the TX coast with a developing thunderstorm cluster in the middle Rio Grande Valley. Strong to severe thunderstorms will likely be ongoing over central TX. Severe gusts/wind damage appears to be the predominate threat with the early-day MCS. As the surface low deepens, a concurrent strong low-level mass response will occur and the development of a 50-kt LLJ by mid morning is expected. Strong low-level moist advection on the nose of the LLJ will be favorable for a continuation of early morning storms as the LLJ's terminus shifts eastward from east-central TX into the ArkLaTex by mid-late afternoon. A concentrated zone of higher probability wind potential may be realized with a potential bowing system as increasing buoyancy (1000-3000 J/kg MUCAPE) and strong shear lead to an intense bowing MCS moving from TX into the ArkLaTex.
Coincident with the diurnal heating cycle, free warm sector thunderstorm initiation is likely from east TX into LA on the northern rim of the elevated mixed layer's stronger capping inversion (north of Interstate 10). Persistent south-to-north oriented confluence zones in the warm sector will serve as the genesis areas with gradual thunderstorm/supercell development as stronger updrafts penetrate the LFC---beginning as early as the late morning and through the afternoon. A moderate to very unstable boundary layer (MLCAPE ranging from 2000-3000 J/kg) is forecast from eastern parts of TX into LA. Forecast soundings show large hodographs (200-400 m2/s2 0-1 km SRH) with strong effective shear of at least 50-kt. It seems plausible several supercells may evolve from this activity and pose a threat for tornadoes and large to very large hail. A couple of strong/damaging tornadoes are possible. The latest model guidance suggests thunderstorm coverage will be less generally south of Interstate 10. Nonetheless, models show isolated to widely scattered storms developing perhaps in conjunction with stronger deep forcing for ascent.
During the evening and overnight over the lower MS Valley, storms will likely spread into the region from the west. Increasing moisture/buoyancy as the maritime front advances northward will favor an organized severe storm risk continuing into the region. Thunderstorms within the strong flow fields will conditionally support the possibility for wind damage and tornadoes after dark.
COASTAL HAZARD MESSAGE NATIONAL WEATHER SERVICE NEW ORLEANS LA 441 AM CDT SUN APR 2 2017
.STRONG SOUTHEASTERLY WINDS WILL DEVELOP TODAY AND INCREASE SUBSTANTIALLY OVERNIGHT AS A SURFACE LOW DEEPENS OVER NORTHEAST TEXAS AND EASTERN OKLAHOMA. THE PRESSURE GRADIENT WILL BE SUCH THAT SOUTHEAST WINDS REACH 25 TO 30 KNOTS WITH HIGHER GUSTS. THIS WILL CAUSE TIDES TO INCREASE ON SOUTH TO SOUTHEAST FACING SHORES.

...COASTAL FLOOD ADVISORY IN EFFECT FROM 1 PM THIS AFTERNOON TO 7 PM CDT MONDAY...
THE NATIONAL WEATHER SERVICE IN NEW ORLEANS HAS ISSUED A COASTAL FLOOD ADVISORY, WHICH IS IN EFFECT FROM 1 PM THIS AFTERNOON TO 7 PM CDT MONDAY.
* COASTAL FLOODING...TIDES 1 TO 2 FEET ABOVE NORMAL.
* TIMING...PEAK TIDES WILL BE IN THE EARLY AFTERNOON HOURS TODAY AND TOMORROW.
* IMPACTS...MINOR FLOODING OF LOW LYING AREAS AND ACCESS ROADS NEAR TIDAL LAKES...BAYS AND INLETS AS WELL AS THE OPEN COAST OUTSIDE THE HURRICANE PROTECTION LEVEE SYSTEMS.
A COASTAL FLOOD ADVISORY INDICATES THAT ONSHORE WINDS AND TIDES WILL COMBINE TO GENERATE FLOODING OF LOW AREAS ALONG THE SHORE.
SKYSUMMIT: I'm thinking this hurricane season will keep us a little busy. Nothing scientific, but just the idea that it really hasn't been hyped that much.

coffeecups: That 'some rain on Friday' became a tornado about 3 miles away (as the crow flies). What a surprise! Glad I didn't have any flooding!

SKYSUMMIT: Yea, other than maybe some rain on Friday, we may be in a dry stretch.

May 1, 2017 21:22:36 GMT -6
SKYSUMMIT: Actually Coffee..I haven't been around that much either. At least not nearly as much as I used to. Work has been extremely busy! It's a busy busy time in real estate

coffeecups: Came home to Harvey from Slidell. Had a little rain here and there. There was no rain in Slidell when I left at 3:30pm. While in NO EAST, I saw where it looked like it was storming around Covington going towards Slidell. Wet but no rain when I got home
