High pressure is sliding to the east, with a milder southerly flow keeping readings in the mid-40s to low 50s overnight, after a Saturday morning frost/freeze.
Clouds will thicken in advance of a weak cold front that is moisture-starved, so only an isolated shower is possible early Sunday.
The weather for the 40th Nationwide Children’s Hospital Columbus Marathon and 1/2 Marathon will be mainly cloudy, with a light southeast breeze, and perhaps a passing shower when the race begins at 7:30 a.m. The clouds will break by afternoon and temperature will rise into the pleasant low 70s in the return flow around high pressure.
The next opportunity for widespread rain will come from a frontal system over the Midwest that will bring showers and scattered storms Monday afternoon, ending early Tuesday. A few storms could be strong with ample wind shear and modest instability in the evening.
Seasonably cool and dry weather will prevail behind the system Tuesday through Thursday. Another cold front will bring a chance for rain on Friday.
Post-Tropical Storm Nestor made landfall on St. Vincent Island, Florida, earlier, and will track northeast as a windy rainstorm across the Southeast, and off the Mid-Atlantic coast Sunday.
