.DISCUSSION...(This evening through Sunday)
Issued at 412 PM CDT Sun Jul 10 2022

The main concerns for this afternoon and evening are temperatures in
the triple digits in areas, near-critical to critical fire weather
conditions in the southwestern part of the area, and the potential
for a few strong to severe thunderstorms.

Conditions remain hot to the south with temperatures currently in
the 90s and 100s.  Heat index values of 100-110 degrees remain
possible for the next few hours.  A Heat Advisory remains in effect
until 8PM this evening.

Near-critical fire weather conditions remain possible for a few
more hours across Furnas, Harlan, Phillips and Rooks counties.
Minimum relative humidity values may approach 20 percent with wind
gusts nearing 25 mph for a brief period of time.

Scattered thunderstorms are expected to develop this afternoon along
and north of a weak frontal boundary.  Strong to severe storms will
be possible this afternoon and evening with the main hazard being
strong to severe wind gusts, although some small hail cannot be
entirely ruled out.  Later in the night, another round of showers
and thunderstorms may be possible, moving in from the north.  These
storms may also bring some wind and isolated hail.  As far as
rainfall, this afternoon/evening/overnight appears to be the best
chance for precipitation for the next several days.

Monday, a cold front will move through the region during the day.
Isolated thunderstorms will be possible along the front late in the
day.  Right now the best chance for storms appears to be in North
Central Kansas.

An upper ridge builds over the western CONUS through mid-week,
shifting to the east, over the Central Plains.  After a break from
the heat on Monday and Tuesday, temperatures begin on a gradual
warming trend through the end of the week.  High temperatures will
once again reach the upper 90s and into the low 100s by Thursday and
Friday.  Precipitation chances will be minimal through this
timeframe.

Looking at the extended temperature and precipitation outlook for 6-
10 days out, temperatures are expected to remain above normal.
Precipitation chances are expected to be below normal.

.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Tuesday)
Issued at 556 PM CDT Sun Jul 10 2022

The winds will start off southerly and look to become northerly
tomorrow morning as a cold front will move through the TAF sites.
Looking at latest model runs along with current radar trends will
keep a mention of VCTS in the TAFs this evening. Currently have
VFR in the TAFs, but if a TSRA moves over the sites sites could go
down to IFR briefly.

...STRONG WINDS POSSIBLE FROM HEAT BURSTS OVER BUFFALO AND
KEARNEY COUNTIES...

At 917 PM, strong winds and a rapid but brief warming spike in
temperatures occurred near Kearney in Buffalo County. This rare
weather phenomenon called a heat burst will remain possible over
parts of both Buffalo and Kearney Counties through 1030 PM.

Heat bursts are caused by decaying thunderstorms and only develop
in an extremely unique environment. The rare setup for a heat
burst is dry air directly beneath a weakening elevated
thunderstorm. When a thunderstorm is weakening, air within the
thunderstorms begins to sink. If this sinking air is very dry and
high enough, it will begin to accelerate toward the ground since it
is more dense. Any remaining precipitation will fall through this
dry air and quickly evaporate. As the air continues downward, it
warms rapidly due to compression.
