From OUN: A Tale of Two Hodographs: For whatever reason today, the environment just ahead of the dryline (currently shown on the FDR VAD) has shown a tendency toward veered near-surface winds, which is leading to a much less-favorable hodograph structure than further east in the warm sector (shown on the TLX VAD). This has likely tempered our tornado risk closer to the dryline throughout the day and explains why some of the more impactful tornadic circulations occurred well into the warm sector (what we saw in Garfield County, the tornado in WFO Tulsa's area a bit ago).
