Is this finally the one that breaks through? All the usual caveats about suppression but we are fighting with two arms behind our back until we get colder air near us.
The low placement struggle/dual areas of Lowest pressure have been a problem on several suits for over 24 hours now. It does mess up the ground result in a big way as you suggested.
HRRR show a dual barrel area of lowest pressure with one SLP into SW PA at 28 and another in NC at 29. It is the model reflecting around to the location of the lowest pressure. But 850's are initially lost in SW PA due to it.
