SAVANNAH, GA (WTOC) - UPDATE - The vast majority of rain over the next three days will fall Monday. Monday remains a First Alert Weather Day. Tuesday is no longer a first alert weather day. Rain remains isolated the second day of the work-week and will have only a low impact on plans.
Summary; A significant rain-maker will produce widespread rain and, possibly, the heaviest rainfall totals so far this year.
Impact; Widespread steady rain, and a few heavy downpours, will slow Monday morning's commute and may have you altering Monday plans.
By sunrise Sunday morning, clouds will be thicker and an isolated shower or two is possible. Whatever rain develops Sunday is forecast to remain isolated, with the greatest chance of rain not arriving until early Monday morning.
Sunday begins with temperatures in the mid-50s to mid-60s; warmest at the beach. Afternoon temperatures reach highs in the lower to mid-70s in most areas.
An area of low pressure allows plentiful rain to develop to our west and southwest Sunday evening. Rain overspreads the Coastal Empire and Lowcountry early Monday.
Nearly everyone will see significant rain, and some will get soaked; accumulating more than two inches of rainfall between Monday and Tuesday mornings.
The severe weather threat remains very low. One or two storms may produce gusty winds to 40 MPH and occasional lightning, in addition to heavy rain.
I'll have updates on TV this evening, at wtoc.com and in the WTOC Weather App.
