This Hazardous Weather Outlook is for southwest Iowa, west central
Iowa, east central Nebraska, northeast Nebraska and southeast
Nebraska.
.DAY ONE...This afternoon and tonight.
Strong to severe thunderstorms are expected to develop after 4 PM,
initially across northeast Nebraska before spreading south and east.
Large hail (2+ inches), damaging wind gusts, and a few tornadoes
(possibly strong) are the expected hazards. Heavy rain due to
several storms moving over the same area may result in some concerns
for flash flooding. A Tornado Watch has been issued for the northern
portion of the outlook area through 10 PM.
.DAYS TWO THROUGH SEVEN...Monday through Saturday.
Additional strong to severe storms are forecast for Monday
afternoon, with an increased threat for large hail (2-4+ inches) and
strong tornadoes. Additional chances for heavy rainfall on top of
what has already fallen since Friday night will result in a potential
for flash flooding, particularly for portions of southeastern
Nebraska. Chances to see severe storm activity is maximized over
southeast Nebraska.
.SPOTTER INFORMATION STATEMENT...
Spotter activation may be needed. Any reports of hail, strong winds,
tornadoes, flooding or damage are greatly appreciated today and
Monday.

.DAY ONE...This Afternoon and Tonight
Gusty south winds from 20 to 30 mph with gusts up to 45 mph
through early evening.
Scattered severe storms are possible after 5 PM across north central
Kansas. These storms may form into a line as they move east southeast
this evening. Very large hail, damaging wind gusts, and a few
tornadoes are the main hazards. Localized flooding is also a
concern if storms train over areas that received heavy rain the
previous evening.
A Flood Watch remains in effect from 7 PM this evening through 7
AM Tuesday morning for areas along and north of I-70. Widespread
rainfall totals of 2-4 inches are expected with locally higher

afternoon with sustained winds of 20-30 mph and gusts upwards of
45 mph into the early evening. A Wind Advisory remains in effect
for Dickinson, Morris, Lyon, Geary and Wabaunsee counties from 9
AM to 9 PM Monday.
The greatest chance for severe weather is still shaping up to be
Monday afternoon and Monday night. There is good confidence in
storms developing over north central KS by the early evening and
move across all of northeast and east-central Kansas through the
night. Storms will be capable of producing tornadoes, very large
hail, damaging winds and flash flooding. People should be prepared
for thunderstorms impacting the area.
