Area Forecast Discussion
National Weather Service Goodland KS
539 AM MDT Wed May 26 2021

.SHORT TERM...(Today and Friday night)
Issued at 311 AM MDT Wed May 26 2021

A few showers have developed in Eastern Colorado this morning. These
showers are expected to lift to the north and out of the area
through the morning.  Southwest flow aloft will be in place over the
Central High Plains for much of the day with an upper low to the
northwest of the area.  Through the day, a mid-level, shortwave
trough will move into Central and Eastern Colorado and a dryline
will be situated to the south of the area over portions of Texas.  A
boundary will be set up over the Tri-State area this afternoon and
the overall environment will become more unstable through the
afternoon.

There is still some uncertainty as to the timing of the onset of
showers and storms this afternoon, although the best chance appears
to be after 21Z.  All modes of severe weather are expected this
afternoon and into tonight as storms move across the region.  Due to
recent rainfall within the forecast area, precipitable water values
of over 1 inch and moisture advecting into the region, there remains
concern that any storms producing heavy rainfall could cause some
issues with flash flooding.

Cooler temperatures and quieter conditions are expected Thursday as
the trough moves out of the region and a cold front moves through.
High temperatures will range from the low 70s in the northeastern
part of the area to the upper 70s/low 80s in the southeastern part
of the area.  Lows Thursday night will be primarily in the mid-40s.

Friday, a disturbance moves through to the south of the area. Most
of the precipitation should stay to the south and west of the area,
although the southwestern part of the CWA may get clipped with a few
showers.  Temperatures will be in the 70s for highs and range from
the upper 40s to low 50s for lows.

.LONG TERM...(Saturday through Wednesday)
Issued at 305 AM MDT Wed May 26 2021

The holiday weekend and the extended forecast looks active and
wet across the Tri- State Region. Models have several upper level
shortwaves moving across the region over the weekend into early
next week. By 12Z Wednesday/21st an upper trough is across the
Plains with an upper level ridge is across the west.

At the surface...On Saturday a cold front is projected to be
across ND southwest to western Nebraska and into northern
Colorado. A surface low will be across northeast NM with a surface
trough across eastern Colorado and a dry line across eastern
NM/west TX region. On Sunday...the cold front is across NW MN
southwest to central SD. It becomes stationary from central SD
southwest into northern Colorado and southwest to southern NV. A
surface low is across southern CO with dry line across eastern
NM/west TX region. A surface trough is across eastern CO. On
Monday a stationary boundary is projected to be across Central
Nebraska southwest to central CO. A surface low across eastern CO
with a warm front across western KS southeast to Central OK. By
Tuesday a stationary boundary is projected to be across se
Nebraska southwest to TX Panhandle region.

Expect afternoon high temperatures to be below normal in the
extended forecast due to the clouds and precipitation forecasted.
Afternoon high temperatures in the lower 70s to lower 80s on
Saturday. By Sunday afternoon high temperatures only projected to
be in the middle 60s to middle 70s by Sunday and through Tuesday.
By Wednesday expect temperatures to be a little warmer but mainly
in the 70s.

Again the extended looks active and wet and maintained plenty of
precipitation chances. Concerned we may see more flooding
potential across parts of the CWA.

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 536 AM MDT Wed May 26 2021

VFR conditions are expected at KGLD and KMCK terminals through
much of the forecast period. A few ongoing thunderstorms this
morning may move into the vicinity of KGLD but omitted the mention
for now due to low confidence. Strong to severe thunderstorms are
expected to impact both terminals between 21Z and 05Z.
