Our low-level flow has started to turn out of the south, allowing for warmth and moisture to begin advecting into the region. In addition, a weak perturbation in the mid-level flow will pass by and allow for high clouds to stream in overnight, preventing optimal radiational cooling and holding temps a few degrees above average.
Unsettled conditions begin to take shape by Wednesday afternoon as a deep upper level low pressure system and its associated surface front continue to track east from the Plains and Great Lakes. A surface warm front will edge northward Wednesday afternoon and bring a spotty light shower or two but I think most spots will remain dry. Thursday will then be the warmest day of the forecast period as temps climb well into the 60s!
