Southerly winds will send warm air into Missouri Monday and Tuesday causing temperatures to climb into the low-to-mid 80s during the day with overnight lows near 60. The 30 year average high this time of year is 70 in Columbia. Although it will be very warm, we are unlikely to break the record highs which are 91 set in 1910 for the 29th and 90 set in 1942 on the 30th.
