A fall cold front will sweep across the area tonight bringing widespread showers and thunderstorms and much cooler weather by tomorrow.
For tonight, we’re looking at a line of scattered showers and thunderstorms gradually sweeping south and southeast overnight. No severe storms are expected, but gusty winds will likely precede the storms. Frequent lightning and locally heavy rainfall will accompany some of the storms as well. Storms will spread into the Springfield area by midnight and to a line from Rolla southwest to Harrison by 2 am. Storms will spread east and southeast to an Eminence to Mtn. Home line by 4 am. Additional scattered showers and isolated thunderstorms will follow the line keeping the threat for rain around into Tuesday morning.
Rain amounts will be spotty, with most locations picking up under half an inch. Locally higher amounts over an inch are possible though.
Temperatures will be sharply cooler on Tuesday with morning lows in the upper 50s and low 60s.
Additional light showers or sprinkles will move across the area into Tuesday afternoon, especially along and south of the interstate, ending from west to east during the afternoon.
Some afternoon sunshine will push temperatures back up through the 60s with afternoon highs in the upper 60s and low 70s.
A chilly night will follow. In fact, it will be the first round of lows in the 40s for many locations and the coolest readings for many since late May.
A sunny, mild day will follow for the official arrival of fall Wednesday afternoon. Sunny skies will come with breezy north winds and highs near 70°.
Thursday morning will be even chillier with lows in the 40s across the Ozarks. Typically colder locations over Southwest Missouri might even dip close to 40°.
Another round of sunny and mild weather will follow the morning chill on Thursday. Afternoon highs will be in the mid-70s.
A pop in temperatures will come ahead of a cold front Friday with afternoon highs in the low 80s. Sunny and mild weather will follow on Saturday. Another pop in temperatures will come Sunday into Monday ahead of yet another cold front. Afternoon highs both Sunday and Monday will be in the 80s.
The pattern will make it very tough for fronts to squeeze out any rain and dry weather is expected into next week.
