TONIGHT: Isolated to scattered storms along and south of the I-70 corridor likely just before midnight through daybreak. Brief heavy downpours possible with lightning, but severe weather isn't expected. Lows around 60 degrees.
TOMORROW: Rain exits southeast early leaving us with partial cloud cover. Slightly cooler with highs in the lower 80s.
EXTENDED: A weak front is moving into Mid-Missouri this afternoon, and as the low level jet stream ramps up tonight, moisture will stream along that boundary and enhance storm development. Isolated to scattered storms are expected to erupt shortly before midnight and continue through the overnight hours along and south of I-70. Some storms could have brief heavy downpours and lightning but severe weather potential is limited. Showers are expected to be to our southeast by mid-morning, leaving us with scattered clouds and highs in the lower 80s by late afternoon. The front looks to linger across southern Missouri into Thursday, keeping a few clouds in the area. Otherwise, the upper pattern remains locked in with low pressure to our west and across the East Coast, keeping high pressure over the region. This means temperatures will remain above average in the mid-upper 80s through the weekend into next week, with no major pattern shift or rain chances until at least the middle of next week.
