This hazardous weather outlook is for northwest...north central and
west central Missouri...as well as extreme eastern Kansas.
.DAY ONE...Through tonight.
Please go to https://weather.gov/media/eax/DssPacket.pdf for more information on
potential weather hazards.
.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.
The probability for widespread hazardous weather is low.
.KEY MESSAGES...
- Showers and embedded thunderstorms continue through the
morning hours. More sparse coverage has overall lowered
flooding concerns; however, isolated flooding remains possible
from heavy downpours.
- Warmer air lifts northward through the day. Areas where it
rains after sunrise range from the mid 70s to mid 80s while
places south of the boundary reach the low to upper 90s with
heat index values of 100-105F.
- The overall weather pattern from the past 2-3 days is expected
to continue with the potential for another prolonged rain
event over the weekend into next week. Then the pattern looks
to become a little more progressive.
