...UPDATE TO AVIATION...

.SHORT TERM...(This afternoon through Monday night)
Issued at 1150 AM CDT Sun May 2 2021

Instability was beginning to build as of midday, with dewpoints
well into the 50s for most zones, and lower 60s across eastern
areas. NAM continues to project 2000-2500 J/kg CAPE east of the
dryline by late afternoon, as strong low pressure deepens near
Dalhart, Texas (987 mb on HRRR, 984 mb on NAM). Convection through 7
pm will be limited, but there will probably be some convection near
the southwest zones by evening, in the convergence zone northeast of
the strong surface low. In this drier air, some outflow winds are
possible from this activity, but coverage and impacts are expected
to be limited.

Much higher confidence of a strong thunderstorm complex
organizing over NE Colorado/NW Kansas by 7-8 pm this evening.
Various CAMs, HRRR and 12z NAM all agree impacts from this
MCS will be greatest along and especially north of K-96 this
evening. Given the linear nature of the upscale growth expected
along the surging cold front (and the impressive bowing on the
CAMs) severe/damaging wind gusts will be the primary threat this
evening. Wind gusts of 60-70 mph are probable, and coordinated
with SPC about upgrading severe wind probabilities (30%/enhanced).
Per SPC's 1630z outlook, wind gusts of 70-80 mph are possible
from the organized bow echo along the I-70 corridor. Best guess is
the tail end of this line will track in proximity to US 50 this
evening, but isolated storms are possible south of US 50 as well.
Strong outflow from the complex will propel an already strong cold
front, surging it south through SW KS around midnight. Pressure
gradients immediately behind the MCS and north of the strong
surface cyclone in the Texas panhandle will be intense for a few
hours tonight, and will need to monitor for high wind/convective
wind products. Followed the stronger MAV guidance overnight, which
focuses the strongest winds/gusts along the preferred US 83
corridor. Increased pops to the definite category for the northern
zones tonight, and included damaging winds in the grids for areas
north of K-96.

A sharp change on tap for Monday in the post cold front
environment. Clouds and intense north winds will continue during
the daytime hours, and temperatures will consequently struggle.
12z NAM/GFS both cool 850 mb temperatures to near 4C at Dodge City
by late afternoon, keeping many locations in the lower to mid 50s.
MOS guidance continues to trend down, and followed that trend.
North 850 mb winds are sustained at about 40 mph all day long, so
gusts of that magnitude are expected. Finally, 12z NAM has come into
alignment with what ECMWF runs have been showing for days, with
widespread rain Monday afternoon. Increased pops to the 90% range
across the preferred southern and western zones, where rainfall
amounts near/over 0.50 inch look probable. Extended HRRR also shows
numerous rain showers blossoming Monday afternoon. CAPE appears to
be completely eliminated Monday, so took out any mention of thunder.

Rain will persist across primarily the southeast zones for much of
Monday night, as north winds gradually relax. Although clouds are
expected to hold in place through sunrise Tuesday, lowered minimum
temperatures to the upper 30s for many zones Tuesday morning.

.LONG TERM...(Tuesday through Sunday)
Issued at 210 PM CDT Sun May 2 2021

Quiet weather will prevail Tuesday through at least Friday, with
few if any impacts. Given this, and the complexity of the short
term, NBM guidance was generally accepted for the long term with
no modifications.

Much improved weather is expected Tuesday, as sunshine and much
lighter winds return. With light easterly boundary layer flow,
afternoon temperatures will still be about 10 degrees below
normal, in the 60s. Still a pleasant spring day, especially
compared to Monday.

A weak shortwave embedded in the NW flow aloft will zip through on
Wednesday. Moisture and instability will be limited, and model QPF
is also limited, so just accepted NBM's minimal pops across the
northern zones for now. Rainfall will be limited.

Dry weather and a warming trend are expected Thursday and Friday,
as a midlevel ridge axis slowly expands eastward from the Great
Basin to the Rockies to the high plains. Strong south winds and
afternoon temperatures in the 80s will return by Friday as lee
troughing reorganizes.

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1043 PM CDT Sun May 2 2021

Low level stratus is expected to develop along and behind a cold
front pushing southeast across western/central Kansas overnight,
resulting in primarily MVFR cigs developing in vicinity of all TAF
sites generally after 08-10Z. Brief periods of IFR cigs will also
be possible through daybreak. North winds 20 to 30kt with gusts
up to 35kt will develop west to east behind the aforementioned
cold front as it moves southeast into northern Oklahoma by daybreak.
Gusty winds may subside somewhat but are expected to persist through
Monday afternoon.
