112 PM CDT Fri Mar 31 2023

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

.DAY ONE...Today and Tonight.

Weather hazards expected...

  Elevated tornado risk.
  Limited hail risk.
  Limited thunderstorm wind damage risk.
  Elevated lightning risk.
  Elevated excessive rainfall risk
  Extreme non thunderstorm wind risk.
  Extreme fire weather risk.

DISCUSSION...

Scattered severe thunderstorms will continue to develop and
rapidly track northeast across the Missouri Ozarks into early this
evening. Storms will exit the eastern Ozarks by 8 PM.

There is an Enhanced Risk for severe storms east of the Highway
65 corridor with a Slight Risk for severe storms extending as far
west as the Interstate 49 corridor.

The primary potential hazards from these storms will be hail to 2
inches in diameter, damaging wind gusts to 70 mph, and tornadoes.
A few strong tornadoes are possible generally near and east of the
Highway 63 corridor.

Outside of thunderstorms, strong and gusty south to southwest
winds will persist today. Gusts of 45 to 60 mph will occur at
times, with the strongest gusts occurring this afternoon near and
west of the Interstate 49 corridor.

The combination of the strong winds and rapidly falling humidity
will lead to critical fire weather conditions across southeast
Kansas and western Missouri this afternoon and evening,
especially in grassy areas. Fires in these conditions will
rapidly grow and spread.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.

There will be the potential for frost development across portions
of the eastern Missouri Ozarks Saturday night into Sunday
morning.

Another strong low pressure system will bring showers and storms
back to the region along with the potential for severe storms and
flooding next Tuesday into Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed into early this evening east of
Interstate 49.
