This Hazardous Weather Outlook is for south central Nebraska and
portions of north central Kansas.
.DAY ONE...Overnight.
Mainly between midnight and sunrise Monday, our entire forecast
area stands at least a slight chance of spotty thunderstorms, but
with the overall-highest chances and potentially most widespread
coverage favoring Nebraska counties along and north of Interstate
80.
Although most storms overnight should be fairly weak, a few could be
strong to marginally severe, with the main threats being 50 to 60
MPH winds, and perhaps hail up to around the size of quarters.
Any wind threat would be enhanced if storms are able to organize
into a larger scale line or complex, but it is unclear whether this
will occur.
.DAYS TWO THROUGH SEVEN...Monday through Saturday.
- Monday and Tuesday heat concerns:
On Monday afternoon and early evening, heat index values across
nearly our entire forecast area are forecast to reach at least 100
to 104 degrees, with some counties especially east of Highway 281
perhaps reaching 105 or slightly higher.
Tuesday should be slightly cooler, but still with above-average
heat, with limited areas mainly near and south of the Nebraska-
Kansas border perhaps reaching a 100 degree heat index.
- Monday severe thunderstorm potential:
Mainly Monday evening-overnight, there is a chance for at least
scattered thunderstorm across much of our forecast area. Some of
these storms could be severe, with the main threats being wind
gusts to around 60 MPH and hail up to around the size of quarters.
- Additional thunderstorm chances:
At least low-end chances for spotty storms exist Tuesday into
Tuesday night, with additional, intermittent and potentially more
widespread chances arriving between Thursday night and Saturday.
.SPOTTER INFORMATION STATEMENT...
Spotters are encouraged to report any hail, wind gusts of 50 MPH
or higher, or localized flooding that might occur overnight.
