Forecasters were down on the Texas and Louisiana Gulf Coast today monitoring the severe weather. While there were ongoing storms, differences were noted between LightningCast V1 (ABI only) and LightningCast V2 (ABI+MRMS). Starting at around 1901 UTC, V1 had much broader probabilities over the thick anvil shield when compared to V2. V2, with the additional input of reflectivity at -10C, was able to provide better predictions over this region, helping forecasters not to erroneously tell DSS partners in the region of impending lightning. Towards the end of the time period, both versions showed higher probabilities as convection started to move into the area.
