Area Forecast Discussion
National Weather Service Goodland KS
447 PM MDT Fri May 14 2021

.MESOSCALE DISCUSSION...
Issued at 409 PM MDT Fri May 14 2021

Key Message:
Storms developing over the favored higher terrain area of the
Palmer Divide will be moving eastward into the forecast over the
next hour and will continue into early this evening. Storms are
expected to become more numerous and increase in strength with
some storms becoming severe as they move across the forecast area
through the evening, before weakening and moving out of the area
around midnight Mountain time.

A frontal boundary extends from central Colorado into south
central Nebraska.  Moist upslope easterly flow on the north side
of the front is transporting 50-55 degree dewpoint air westward
into far eastern Colorado and northwest Kansas with dewpoints
over central Kansas on the other side of the front in the upper
50s. Storms moving east over the plains will encounter greater
instability where temperatures and dewpoints are higher mainly
south of the boundary, and higher shear in the vicinity of the
frontal boundary, which would initially coincide with the area
mainly along and south of Interstate 70. That favored instability
and shear area will transition eastward through the evening along
with the frontal boundary as an upper level short wave trough
moves eastward across the forecast area through the evening. That
short wave and frontal boundary will move east of the forecast
area after 06Z with instability and shear weakening overnight and
moving east of the forecast area after 06Z.

&&

.SHORT TERM...(This evening through Saturday night)
Issued at 243 PM MDT Fri May 14 2021

Satellite and 500 mb RAP analysis showed northwest flow over the
region early this afternoon, with a shortwave moving into Colorado.
Weak ridging was observed from the Four Corners region up towards
the Great Basin. Mid to high level clouds developed off the Rockies
as the shortwave approached, gradually pushing into the region while
storms form along the Front Range. At 2 PM MT, northeast winds were
observed at 10 to 15 mph with temperatures in the upper 60s to low
70s.

A few thunderstorms are expected to move into eastern Colorado
during the mid to late afternoon hours. Storms are expected to
increase in coverage (likely becoming a cluster or two) as they
progress east into northwest Kansas and extreme southwest Nebraska
during the evening hours and the shortwave kicks through the area.
Shear near 40 knots (increasing to near 60 knots in the evening),
CAPE of 1000 to 2000 J/kg, and steep lapse rates will support severe
thunderstorms this afternoon and evening. The main hazards initially
appear to be large hail and damaging winds. Although a tornado
cannot be ruled out, dry air at the surface and high LCLs will
really limit tornado development for this event. As storms
transition to a complex tonight, concern turns more towards a
damaging wind and heavy rainfall threat. PWATs nearing 1 inch
(with 1.25" not out of the question for eastern portions of the
area), suggest that locally heavy rainfall will need to be
monitored. Thunderstorm activity slowly exits the region to the
east/southeast overnight into early Saturday as temperatures fall
into the mid 40s to mid 50s.

Another point to quickly mention...There appears to be a signal
for fog returning to the region late tonight into early Saturday,
although it looks more widespread than previous nights. The fog
and stratus are forecast to set in after midnight. Reduced
visibilities could cause hazardous travel for the morning commute.
However, locations that will be most impacted is uncertain at
this time.

For Saturday, some guidance shows showers and storms lingering along
the Nebraska border and eastern part of the area into the morning
hours. There should be a lull midday before another round of
thunderstorms develops in the afternoon. The setup will be similar
to today. Looks like a few storms will initiate along a surface
trough in eastern/central Colorado during the afternoon before
pushing east and forming a cluster once again. While shear appears
to be lower, steep lapse rates and good instability indicate that
large hail and damaging winds are potential hazards. Otherwise,
expect highs in the upper 60s to low 70s tomorrow, and lows in the
50s Saturday night.

.LONG TERM...(Sunday through Friday)
Issued at 155 PM MDT Fri May 14 2021

The long term period is looking unsettled with near constant chances
for rain through the week. Temperatures look to be near average with
highs around 70.

Sunday starts with slight ridging aloft at 500mb that will
transition to more of a laminar flow out in front of an advancing
cut-off low. The cut-off low will then slowly move towards and into
the area during the early week before diffusing out into the larger
flow. The end of the week looks to have the ridge set up over the
Eastern CONUS while a trough moves into the Western CONUS. This
pattern may provide some slight synoptic support for storms but
looks to be relatively weak in flow and potentially even split the
flow.

Near the surface, the Tri-State area appears to be between two
larger areas of high and low pressure with higher pressure to the
east under the upper ridge and lower pressure to the south and west
as the cut-off low moves closer to the area. With lower pressure to
the south, moisture is forecasted to be pulled from the Gulf of
Mexico north into the area. The question becomes how much of this
moisture will be realized and actually pulled into the area.
Guidance has been shifting the lower pressure further south in more
recent runs and the precip appears to be shifting south with it.
Also making things more interesting is a nearby cold front that
passes through Sunday and cools temperatures slightly going forward.

What all of this means is that the current forecast calls for rain
and storms for most of the week with the greater rain chances and
amounts currently arriving on Sunday after the front. The rest of
the week may have similarly high chances, but confidence in
coverage and higher rain amounts is low due to the general
shifting of the lower pressure south. Without the support for lift
and if cloud cover from the system in the area limits daytime
heating, storms will likely be lesser in coverage and intensity.
Temperatures are expected to be relatively steady until the end of
the week with highs forecasted in the 60's and 70's. There could
be some variations due to cloud cover or lack there of in certain
locales but this will be clearer as each day gets closer. While
severe threat currently looks to be low for much of the week,
there could still be a chance if clouds break for daytime heating.
There also could be a chance next weekend as a similar setup to
recent days is appearing in guidance with a Front Range low and
southerly flow bringing moisture north. Still plenty of
uncertainty with that solution.

&&

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1146 AM MDT Fri May 14 2021

Vfr conditions are anticipated through the afternoon hours at both
KGLD and KMCK terminals. Thunderstorms look to move into the
region from eastern Colorado during the late afternoon and
evening, prompting a mention of VCTS for KGLD (00 to 03z) and
KMCK (02 to 05z). If any storms come near either terminal, reduced
visibilities from precipitation along with gusty winds could
occur. Behind the storm activity, deteriorating conditions are
forecast as lowered ceilings and fog develop overnight into
Saturday morning. Otherwise, east to northeast winds prevail with
winds around 10 knots or less.
