A strengthening southerly flow will lead to an increase in rain chances early this week, especially in northern and central Florida. In north Florida, from Tallahassee to Gainesville, showers and a few thunderstorms will be possible each afternoon through Wednesday, ending most evenings by sundown.  A possible sea breeze collision will occur during the late afternoon hours for areas along and to the west of I-75 Monday, then near and east of I-75 on Tuesday.  In central Florida, a few morning showers will be possible near the Space and Treasure Coasts. Further inland, along the I-4 corridor, isolated showers and a few thunderstorms are also possible in the afternoon and early evening hours through Wednesday.  South of the I-4 corridor, skies will be partly sunny, temperatures slightly above average, with little or no rain this week.
