Here is what was promised: A January thaw is shaping up this week in the central and eastern states following the icy mess from Winter Storm Jupiter. Parts of the South and East experienced a brief warm-up last week prior to the storm, and several record highs were set in those regions. However, this week's thaw looks to be warmer, more widespread and longer lasting, with the entire eastern half of the Lower 48 experiencing temperatures 15 to 30 degrees above average, at times, for multiple (6) days."
