The weather this week is going to be all over the place. Overnight night lows early in the week will be in the upper teens and 20s, and by the weekend, daytime highs will be near 80°. Definitely a roller coaster ride.
A strong ( and cold ) upper-level low is situated well to our north over the Great Lakes. This low will continue to pump cold, dry air right into the Ozarks. We will be flirting with record lows Tuesday morning, and I think we will easily set record lows on Wednesday morning. A FREEZE WARNING is in effect Tuesday morning. This hard freeze will mark the end of the growing season across the Ozarks.
If you feel like this is early, you are correct! Our average first hard freeze (less than or equal to 28°) doesn’t happen typically until early November. And, this level of cold will not only set new daily record lows but will also challenge the lowest lows ever recorded in October.
We will slowly warm back to seasonal temperatures on Thursday, and then surpass that on Friday and Saturday. An Indian summer is defined as a warm period after a hard freeze. The weekend will qualify as an Indian summer across the Ozarks.
This week does appear to be very dry across the Ozarks. Next week does look to bring a better chance of (much-needed) rain our way!
