... KEY MESSAGE 1...Mainly dry but a few showers will be possible through tonight.
Mainly dry weather will continue ahead of a sharp cold front approaching the Lower Lakes today, although a few showers can`t be ruled out. It will be a bit warmer as southerly flow helps to nudge temperatures up into the 60s for most locales.
