Springfield Local Forecast
SUMMER STORMS AND EXTREME HEAT RETURN
SPRINGFIELD (WICS) - After a brief reprieve from the sweltering heat and humidity, temperatures will be on the rise after some shower and storm chances kick-off the work week.
An upper level low will spin into the Great Lakes the next couple of days with thunderstorm activity rolling into central Illinois as early as late Monday afternoon, but better chances will pick up Monday night and continue into Tuesday. There's even a SLIGHT RISK of strong to severe storms late Tuesday afternoon and early evening as the low pulls a cold front through the area. The strongest storms will be capable of some gusty winds and hail, along with locally heavy downpours. The latest forecast models indicate the potential of at least a half-inch to as much as an inch of total rainfall between late Monday afternoon and Tuesday night.
Once the storm chances clear out, a dome of heat begins building into the Midwest with temperatures climbing back into the low 90s by Thursday and mid 90s into the weekend. Tropical-like humidity will combine with the heat to once again produce heat indices -- the "feels like" temperatures -- in excess of 100 degrees, resulting in Heat Advisories likely being issued later in the week.
THE 7-DAY TEMPERATURE OUTLOOK: Look for highs in the mid 80s Monday through Wednesday; and, low to mid 90s Thursday through Sunday. Overnight lows will fall to the low 70s Monday and Tuesday night; and, mid 70s Wednesday through Saturday night.
