This Hazardous Weather Outlook is for portions of the Missouri
Ozarks and extreme southeast Kansas.

.DAY ONE...Tonight.

Weather hazards expected...

  Limited hail risk.
  Elevated Limited thunderstorm wind damage risk.
  Elevated lightning risk.
  Limited excessive rainfall risk

DISCUSSION...

A line of strong to severe storms will move rapidly south through
much of the forecast area past midnight. Winds to 70 mph and
small hail will be likely. Additional strong storms will be
possible over central Missouri toward morning.

The greatest threat for damaging winds extends north of I-44 and
west of Highway 65.

In addition...these storms will produce very heavy
downpours. The threat for flooding will be limited however due to
the fast movement of the storms.

.DAYS TWO THROUGH SEVEN...Monday through Friday.

A Heat Advisory is in effect for locations along and west of a
Nevada to Stockton to Cassville Missouri line Monday.
Thunderstorms and cloud cover may slow the rise of temperatures
Monday morning but strong recovery is expected by the afternoon.

Hot conditions are expected to continue through the weekend into
next week with heat index values similar each day as they top out
in the upper 90s to 110 degree range. The hottest conditions will
occur across southeastern Kansas and southwestern Missouri.

Thunderstorm chances will continue over the eastern Ozarks on
Monday with some marginally severe storms. Damaging wind will be
the main risk, along with the chance for localized flooding.

The heat will continue to build back up this week with western
Missouri and southeast Kansas remaining the hottest with heat
index values from 105 to 110. This heat will spread to the entire
area by Wednesday and Thursday.

.SPOTTER INFORMATION STATEMENT...

 Spotter activation may be needed later this evening into tonight.
