Pretty much all the models show warmth until the last week of the month unless the CAD is stronger. Its a bit weird for the cold to be coming from the NE this time of year. We used to get strong fronts from the great lakes/Midwest sweeping across the lower 48. None of that really showing up for the next couple weeks at a minimum.
Further SW is really going to be above average the next few weeks. Places like Mississippi could be 90s for multiple days.
