Area Forecast Discussion
National Weather Service Hastings NE
648 PM CDT Mon Jul 24 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.


.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Tuesday)
Issued at 640 PM CDT Mon Jul 24 2017

VFR conditions are expected through the period with light
southerly winds expected overnight...increasing and becoming gusty
out of the south on Tuesday as the pressure gradient tightens
across the region ahead of an approaching cold front. Overnight
tonight...expect a modest LLJ to result in marginal wind
shear...and maintained this mention in the 00Z TAF through the
early morning hours Tuesday.
