18Z NAM even slower with the system moving through on Tuesday morning. That's 3 runs in a row that have trended slower. Tonight's model runs with the new data ingested should paint a much clearer picture for the Metroplex.

Wasn't (at least part of) the issue that the energy was going to beat the cold air here?
If the front is already in the Dallas, would that increase the odds of frozen precip farther south?
