The last couple HRRR runs it has backed away with the idea of super cells ahead of main line which has it arriving SW LA before midnight, instead it has the super cells developing over SE LA before sunrise ahead of it.
What does the possibility of hail look like for the BR metro area? Is it increasing or staying the same?

Mesoscale Discussion 1601 NWS Storm Prediction Center Norman OK 0214 PM CDT Wed Oct 31 2018
Areas affected...parts of east to eastern Texas and far western Louisiana
Concerning...Severe potential...Watch possible
Valid 311914Z - 312145Z
Probability of Watch Issuance...60 percent
SUMMARY...Storms are likely to increase in coverage and intensity by late afternoon across central into east-central Texas, continuing into western Louisiana after 9-10 pm. Damaging winds will be possible initially, with a couple tornadoes increasingly possible through the night.
DISCUSSION...An axis of substantial moisture and instability currently stretches from Deep South TX northward to an approaching cold front. Lift is increasing across the region in association with a leading shortwave trough, with an abrupt wind shift noted above the surface at the DFX VWP. Lift is strongest where this feature intersects the surface front, currently over central TX where a cluster of elevated storms exists.
With time, storms should increase in intensity as they translate southeastward. Severe wind is possible as storms become more linear in a few hours. Veering winds above the surface will mitigate SRH and tornado threat for western parts of the discussion area. However, a tornado threat may eventually materialized over eastern areas.
For southeastern TX into LA, early-day convection has left relatively cool air across the Houston area where showers persist. Area VWPs show marginally favorable wind profiles for supercells, which should get better with time as both the low-level jet and winds aloft increase. Here, effective SRH around 200-300 should develop this evening. As a result, a few storms near the upper TX coast toward southwest LA may become supercells, and a tornado cannot be ruled out. In addition, a burst of new development may occur immediately ahead of any approaching squall line from the west, with tornado threat.

PUBLIC SEVERE WEATHER OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 0310 PM CDT WED OCT 31 2018
...Severe thunderstorms expected over parts of the lower Mississippi Valley this evening and overnight...
* LOCATIONS... Louisiana Southern and Central Mississippi East Texas
* HAZARDS... A few intense tornadoes Scattered damaging winds Isolated large hail
* SUMMARY... The greatest risk for severe thunderstorms, capable of producing damaging winds, hail, and tornadoes, exists from southeast Texas to the lower Mississippi Valley through tonight.
Tornadoes at night can be particularly dangerous because they are usually fast-moving and difficult to see. Stay tuned to NOAA Weather Radio, weather.gov, or other media for watches and warnings. A tornado watch means that conditions are favorable for tornadoes to form during the next several hours. If a tornado warning is issued for your area, move to a place of safety, ideally in a basement or interior room on the lowest floor of a sturdy building.
