AREA FORECAST DISCUSSION
National Weather Service Hastings NE
115 PM CDT Sat Jul 10 2021

...Aviation Update...

.DISCUSSION...(Today through Friday)
Issued at 524 AM CDT Sat Jul 10 2021

Busy shift overnight will make for a brief and later issued
discussion.

Main focus will be on chances of showers/thunderstorms
today/evening.

The last round of MCS activity is on its way out of the CWA early
this morning, with spotty shower/thunderstorm activity for a good
chunk of the early morning. Looks like we get a bit of a lull
toward late morning/early afternoon before a spoke of energy
rotates south and clips our CWA, focusing on our northeast. MLCAPE
increases to the 1000-1500 J/kg range for the most part, with
higher MLCAPE in our east/northeast. Deep layer shear is shunted
south quite quickly this morning, and will be highly lacking,
especially in areas where we have a highest POPs in the northeast
where we are carrying roughly 50 percent chances of precip in our
northeast. Cool mid-level temps indicate that we should have
little problem with producing pulsy thunderstorms that could give
us some marginally severe hail. Although deep layer shear is more
favorable in our south where we may hold on to 25-30 KTS of deep
layer shear this afternoon, MLCAPE in this area will peak in the
1000-1500 J/kg give or take away from the focus of the spoke of
energy mentioned earlier. Chances of thunderstorms diminish by
mid-evening as the mid to upper wave of energy continues to move
south and eventually away from the CWA. With generally low shear
and marginal instability, small to marginally severe hail will be
the primary threat to afternoon/evening storms that develop.
Severe threat diminishes after 9 pm, but some straggler t-storms
could stick around into the overnight. For temperatures, still
looks like we are headed toward near 80, or just under 80, perhaps
a tad warmer from the previous forecast, but still cool. Leftover
sky cover should help keep temps from getting too toasty and
cooler, drier air is moving in behind a cold front that has pushed
into Kansas.

We could have some stubborn stratus and sprinkles/showers hang
around during the early morning Sunday, but for the most part,
Sunday should be dry with subsidence occurring behind the passing
wave from the previous afternoon/night.

Monday and Tuesday remain dry and warmer with chances of t-storms
returning for mid-week with typical highs in the mid 80s to near
lower 90s for the most part.

.AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Sunday)
Issued at 115 PM CDT Sat Jul 10 2021

Ceiling/visibility/precipitation:
Main concerns are: 1) Decent chance of passing
showers/thunderstorms this afternoon-early evening (possibly
briefly strong to marginally-severe) and 2) increasing probability
of potentially several hours of MVFR ceiling late this evening
into late Sunday morning. Starting with the shorter term issue,
have kept a generic "vicinity thunderstorm" (VCTS) through 01Z,
with a TEMPO for -TSRA from 19-23Z to capture the main window of
opportunity for passing storms. Not expecting "high end severe" by
any means, but the most intense storms could contain hail up to
around quarter size/wind gusts 40-50KT. As for ceiling trends, a
lower-end VFR ceiling is certainly possible this afternoon-evening
(perhaps high-end MVFR under any storms), but overall VFR should
prevail until at least 04-06Z. Thereafter, have prevailing MVFR
kicking in through most of the remainder of the period, with
latest models looking more aggressive with lower ceiling
coverage/duration. Have both sites returning to low-end VFR by
15-16Z, but a ceiling could linger. Visibility-wise, cannot rule
out brief MVFR during any storms and perhaps also in light
fog/haze toward sunrise, but with VFR most likely to prevail the
vast majority of the time have kept it VFR for now.

Winds:
Aside from any possible convectively-enhanced winds this
afternoon/early evening, rather breezy north-northwest winds will
prevail through around sunset, with sustained speeds commonly
15-20KT/gusts to around 25KT. By around 03-04Z, a lighter
northerly wind generally around 10KT will be in place, with this
lighter regime prevailing through the remainder of the period.

Webster-Nuckolls-Thayer-
1039 AM CDT Sat Jul 10 2021

This Hazardous Weather Outlook is for south central Nebraska and
portions of north central Kansas.

.DAY ONE...This Afternoon and Tonight.

Anytime between mainly 1 and 8 PM, isolated to scattered
thunderstorm activity is possible almost anywhere in the outlook
area, but with the overall-highest chances favoring Nebraska counties
north of Interstate 80 and also counties along and east of Highway
281. Roughly the eastern half of the outlook area is under a
Marginal Risk for severe storms during this time, with the main
threats being hail up to around quarter size, and perhaps also
wind gusts up to around 60 MPH. However, even west of the official
Marginal Risk area, a few strong storms with small hail and gusty
winds cannot be ruled out.

After roughly 8 PM, any possible threat for strong to severe
thunderstorms will be on the decrease, but a few general, non-
severe storms could linger later into the night, particularly
within counties east of the Highway 281 corridor.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Our next, off-and-on chances for thunderstorms arrive between
Tuesday evening and Friday, with early indications suggesting
some of the most widespread coverage might favor the Tuesday
night through Wednesday night time frame. It is still too early to
confidently assess the potential for severe storms.

.SPOTTER INFORMATION STATEMENT...

Spotters are encouraged to report any hail and wind gusts over 50
MPH that might occur this afternoon into this evening.
