Our forecasters noticed that MESH was running around 1.5″ while hail from the storm was around 2.5″. This is probably due to the strong rotation in the storm per anecdotal evidence from SHAVE.

Our forecasters have issued a Tornado warning for the storm in Custer County. This was based on highly deviant motion and increased rotational characteristics with convergent signatures. This based on 88D and PAR data. PAR scanning stragety is sufficient to monitor storm.

Our forecasters have issued a severe thunderstorm warning for storms in Western Oklahoma (Custer county). Reasoning for the warning was storm structure and organization as revealed through the phased array radar. The scan strategy implemented by the PAR (thunderstorm far with adaptive scanning) was found to be superior to the current strategy implement in KTLX; the superiority was found in the selection of PRT which helped minimize dealising problems.

Getting a late start as the cap has held and lack of upper air features to develop storms. However, storms may be forming in west Oklahoma. Our forecasters are looking are PAR data and WSR-88D data from KTLX.
