The brief period of warmth is being driven by low pressure systems moving in from the Atlantic. While Tuesday will see these elevated temperatures, the outlook shifts toward wetter and windier weather by late Tuesday and into Wednesday.

While many regions will remain dry with clear spells, northern areas are expected to turn chilly. Meanwhile, the far southeast faces an initial risk of heavy rainfall as the weather pattern transitions.
