Area Forecast Discussion
National Weather Service Hastings NE
1234 AM CDT Tue Jul 25 2017

.SHORT TERM...(This evening through Tuesday)
Issued at 403 PM CDT Mon Jul 24 2017

An upper level ridge remains in place across the area today with
dry conditions expected for the next 24 hours. Highs should top
out in the 90s.

Tomorrow looks to be the warmest day of the week with highs in
the mid to upper 90s across the area. Heat indices could reach
into the 100s, although currently have them just below heat
advisory criteria. Winds will be quite gusty out of the south
tomorrow ahead of the advancing cold front which could hopefully
help mitigate some of the heat.

.LONG TERM...(Tuesday night through Monday)
Issued at 403 PM CDT Mon Jul 24 2017

The biggest forecast concern in the extended is the potential for
severe weather and precipitation Tuesday night through Wednesday.
A shortwave trough and a southeastward moving cold front will
push through the area Tuesday night with showers and thunderstorms
possible along it. Although much of this activity will likely
remain below severe limits overnight, a strong to marginally
severe storm is not out of the question.

Heading into Wednesday afternoon, models overall are not
consistent with how fast the system moves out of the area. Current
thinking is that thunderstorms will redevelop in the afternoon
and evening and track across the area.

Once this system moves into Friday a cooler airmass will prevail
as the upper level ridge axis shifts back to the west.
Temperatures will be at or just below normal through the rest of
the extended with highs in the mid to upper 80s. Scattered
thunderstorms are also possible Friday night through Sunday but
most places will likely remain dry.
