A frontal zone initially stalled to the south will return northward as a warm front later this evening into tonight. While mostly dry today, this boundary aids in the return of shower and thunderstorm chances. Additional storm chances are expected to return Wednesday through the weekend, possibly into early next week, as further disturbances pulse through. This comes with seasonably warm and humid conditions. Rain and thunderstorms will be locally heavy at times given the tropical air mass in place. $$
