Today has us in the throes of the Easterlies. Well south-easterlies. This will deign to bring us more heat and humidity, but the light nature of these winds will mean any storms that form will stay put. In the upper atmosphere, the winds remain fairly strong from the east. This means the storms will be sheared and thus can become strong. There is enough instability in the atmosphere (in sfl, this means no subsidence or significant inversion exists), and PWATS hovers around 2″. This is a recipe for SB storms this afternoon which might start a bit earlier due to the light low level flow.
