Severe storms moved through parts of the Ozarks Sunday night prompting the National Weather Service to issue tornado warnings.

There were reports by spotters of tornadoes on the ground near Marionville, Aurora and Diggins.  And the NWS was able to confirm one of those.

"We did find a very brief touchdown just south of Diggins yesterday," said NWS Meteorologist Drew Albert.  "We did have time to send a survey crew out, and they did find I think a very very small area of damage--damage to limbs and one uprooted tree--with that, so it was rated an EF0."

The heat continues today, and for some counties in the KSMU listening area, an excessive heat warning is in effect.

Barton, Cedar, Dade, Dallas, Jasper and Polk Counties are included in that warning from 11 a.m. to 8 p.m. today.  A heat advisory continues for all of southern and central Missouri through Saturday evening. 

In the areas under an excessive heat warning, temperatures will be in the mid to upper 90s with heat index values of 105 to 110.  Other areas are expected to see temperatures in the mid 90s with a heat index around 105.

It may be spring on the calendar, but it won't feel  like it outdoors tonight.  Temperatures will drop into the upper teens to low 20's:  21 is the expected low in Springfield. 

National Weather Service meteorologist, Eric Wise, said the cause is a Canadian air mass that will dip into Missouri.

The cold temperatures will take a toll on plants.  "Any vegetation, especially that's already blooming and sensitive to early spring freezes, will likely be damaged or killed with these temperatures tonight," Wise said.

The Springfield area started out at 66 degrees Tuesday morning, but by late afternoon, temperatures will be in the low 40's.  

A flood watch is in effect through late tonight, and some areas, including Springfield, are under a winter weather advisory from 6 tonight until 10 tomorrow morning.
