Muggy Sunday, with storms holding off until tonight and Monday

Weather

The weather feels more like June this weekend, with temperatures reaching 81 in Columbus Sunday–warmest of the season so far–and moderate humidity, this less than a week after it seemed like we were back in March, dealing with cold winds and snow/graupel.

A warm front lifting north will bring a southerly flow of increasingly warm and humid air. Low pressure developing in the upper Mississippi Valley will drag a cold front into the state late tonight and Monday, accompanied by occasional showers and storms, some with the potential for heavy rain and gusty winds.

A flash flood watch has been issued for Monday/Tuesday for central and western Ohio, with locally 1 to 3 inches of rain possible over the next 48 hours.

Low pressure will track across northern Illinois and then sag southeast beneath a closed off, meandering upper low that will spin over the Ohio Valley for much of the week, keeping the weather unsettled and damp, along with cooler temperatures.

The heaviest rain will arrive around midday on Monday ahead of a cold front, with lighter showers and falling temperatures later in the day, after a lunchtime high in the mid-70s. Much cooler air will follow behind the system, with below-normal highs in the low 60 for a few days.
