AREA FORECAST DISCUSSION
National Weather Service Hastings NE
139 AM CDT Mon May 3 2021

...Aviation Update...

.DISCUSSION...(This evening through Sunday)
Issued at 325 PM CDT Sun May 2 2021

Focus is on thunderstorms/severe weather late this evening/tonight...

The pattern aloft featured west/southwest flow ahead of a couple
shortwave troughs translating through the northern/central Rockies
towards the plains. At the surface, low pressure was centered in
southeast CO with a dry line extending to the south, and a cold
front was oriented to the north into far southwest Neb on into
central South Dakota. Moisture advected north into our region in
southerly flow ahead of the front and dps have risen into the upper
50s/around 60F across much of our cwa. The morning low cloud cover
has become more scattered this aftn, allowing for increasing
insolation and destabilization. The latest SPC meso page shows
instability around 1500 j/kg already and models prog instability
around 2000 j/kg by evening before the cold front arrives.

The progressing cold frontal boundary will provide the focus/lift
for showers/thunderstorms as we head through the evening/overnight
hours with latest CAMs showing initial storm development as early as
5 PM but more so 7-8 PM or after. Storms are expected to align
along the boundary while western convection along the front
range/high plains rolls eastward...with a complex of storms
impacting our region into tonight. Conditions will be favorable
for strong to severe storms...bringing a primary damaging wind
threat with 70 mph winds possible along a line of storms...and
storms will also be capable of producing large hail around the
size of ping pong balls. The latest SPC Day 1 outlook has upgraded
portions of north central KS to an enhanced severe weather risk
and the slight risk extends into southwest Neb.

Heavy rainfall is also a concern from the storms given the moisture
availability with dps around 60F and precipitable water values
ranging from 0.75" to 1.25" (which average 1-2 standard deviations
above normal for this time of year). Our current QPF ranges from
roughly a third of an inch on the low end to around 2" on the high
end and as is the nature of convection...there will be winners and
losers on rainfall with some locations seeing little rain and other
areas could exceed the 2" amount. There is still some uncertainty on
where the axis of heavy rain will align and overall trends have
shifted a little farther to the south/southwest.

Also tonight, the cold frontal passage will be a noticeable one.
Aside from the storms, the front will bring an abrupt wind shift to
the north and wind speeds will ramp up behind the boundary. Wind
gusts of 35-40 mph are expected to be common and would not be
surprised if a few locations see gusts near 50 mph.

For the most part, the convection is expected to depart by daybreak
Monday with perhaps some lingering showers/storms in our eastern or
far southern zones. Monday's weather is not looking overly nice with
noticeably cooler temps, strong/gusty north winds and clouds around.

Towards Monday night, an upper trough moving out of the Central
Rockies is expected to bring another round of precip to portions of
the Southern and Central Plains region, mainly to our south across
KS and have carried buffer pops. Temperaturewise, our northwest
zones are forecast to see some chilly overnight low temps Monday
night/Tuesday morning with readings in the low/mid 30s and some
frost development is possible.

Our region generally stays in a cooler pattern under the influence
of an upper trough for much of the upcoming week, with several days
of highs in the 60s and lows in the 30s/40s. Small chances for
precip return around the middle of the workweek and and return again
intermittently for next weekend. Temps looks to moderate to some
degree late in the week/next weekend with high temps closer to the
70 degree mark.

.AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Tuesday)
Issued at 138 AM CDT Mon May 3 2021

General overview:
We are down to the last 1-4 hours few hours of steady, lingering
light rain (lasting longer at KGRI than KEAR), with dry conditions
then likely through the remainder of the period. The lingering
rain is light enough that VFR visibility will likely prevail from
here on out. Ceilings are a major question mark, as the overall
likelihood/duration of MVFR ceiling appears to have backed off
versus expectations from the 00Z TAF issuance. As a result, have
now confined the window of opportunity for MVFR to the 12-20Z time
frame (and even then suspect it may not be solidly last that
entire time before lifting to at least low-end VFR and/or
scattering out). As for winds, the ongoing convection has actually
kept winds a bit lighter/more variable in direction the past
several hours, but based on upstream obs a steadier/gusty north
wind is not far away, and expect much of especially the 12-00Z
time frame to feature sustained speeds commonly around 20KT/gusts
to around 30KT. Winds will start dropping off again Monday
evening, with speeds by around sunset/especially after easing down
to around 10KT.

Webster-Nuckolls-Thayer-
1221 AM CDT Mon May 3 2021

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

.DAY ONE...Overnight.

Although the threat for severe thunderstorms has ended for the
night, general, non-severe storms capable of producing brief
heavy rain, small hail and wind gusts up to around 45 MPH will
remain possible through around 3 AM in far southeast portions of
the outlook area, particularly within Thayer, Nuckolls and
Fillmore counties.

Due to small corridors of very heavy rain that fell Sunday
afternoon and evening, various Flash Flood Warnings, Flood
Advisories and a Flood Warning remain in effect early this
morning, affecting portions of the following counties: Hamilton,
Adams, Kearney, Phelps, Gosper, Polk, York and Rooks. Please refer
to the Warning and Advisory statements for more details.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Thunderstorm chances exist for various portions of the outlook
area Wednesday afternoon and evening, and then Friday night into
Saturday night. At this time, the threat for severe storms appears
low for Wednesday, but it is too early to confidently assess the
severe storm potential Friday night into Saturday.

Early Tuesday morning, it could get just cold enough to allow
some frost to develop, mainly for locations west of a line from
Cambridge to Loup City to Greeley. However, sub-freezing
temperatures are not anticipated.

.SPOTTER INFORMATION STATEMENT...

Spotters are encouraged to report any flooding impacts,
particularly any possible water covering roads.
