This Hazardous Weather Outlook is for south central Nebraska and
portions of north central Kansas.
.DAY ONE...Today and Tonight.
A few non-severe thunderstorms will be possible across areas
mainly west of Highway 281 through around 10 AM this morning.
Later this afternoon, daytime heating may induce a couple
thunderstorms just about anywhere across the local area, although
coverage should be very limited.
For tonight, an approaching disturbance will bring a better chance
for more widespread shower and thunderstorm activity across the
area. A few of these storms could be on the strong to marginally
severe side, with hail to the size of quarters and 60 MPH wind
gusts possible with the strongest storms.
Finally, with temperatures forecast to climb into the 90s along
with dewpoints in the 70s, heat index values this afternoon will
likely top 100 degrees in spots. While this will be slightly
cooler than the last couple of afternoons, it will still be
uncomfortably hot for many.
.DAYS TWO THROUGH SEVEN...Monday through Saturday.
Heat index values will again climb to near 100 degrees during the
afternoon hours both Monday and Tuesday.
There will be a chance for Thunderstorms across the area both
Monday and Tuesday, focused mainly during the evening and
overnight hours each day. A few of these storms will be on the
strong to marginally severe side, with hail to the size of
quarters and 60 MPH wind gusts possible with the strongest storms.
Additional thunderstorm chances are anticipated with a cold front
on Friday. At this point, it remains too early to accurately
assess the severe weather potential late in the week.
