.SHORT TERM /THROUGH MONDAY NIGHT/...
Issued at 259 PM MDT Sun May 5 2024

Visible satellite imagery shows cloud cover continues over most of
the Goodland CWA this afternoon.  There is some clearing occurring
in the far western portions of Kit Carson and Cheyenne counties in
Colorado.  Expect at least partial cloud cover to continue for most
locations for the rest of this afternoon and into tonight.

Heading into Monday, a boundary will move across the region during
the morning hours.  There is concern that thunderstorms will
initiate along the boundary around mid-morning, moving to the east
through early afternoon.  A few strong to severe thunderstorms will
be possible with large hail and damaging wind being the main
concerns with any storms.  An isolated tornado cannot be entirely
ruled out.  For most areas, storms should be out of the area by
around 12pm MDT.  A few lingering showers/storms may be possible
into the early afternoon for areas along and east of a line from
McCook to Morland.

Gusty winds and low relative humidity values will be a concern from
mid-morning Monday through Monday evening.  Southeasterly winds will
shift to the west behind the boundary, with winds gusting as high as
45 MPH.  Minimum relative humidity values may fall as low as 10
percent in the afternoon.  A Fire Weather Watch has been issued for
Kit Carson and Cheyenne counties in Colorado, and Wallace, Greeley,
Wichita, and Logan counties in Kansas for Monday.  Fire weather
concerns will lessen as RH values improve around sunset.  Although
limited, a little bit of blowing dust may also be possible.

.LONG TERM /TUESDAY THROUGH SUNDAY/...
Issued at 259 PM MDT Sun May 5 2024

Tuesday, the closed low that brought the boundary through the Tri-
State area, will move up into the Dakotas and eastern Montana. Winds
will remain fairly gusty.  Fire weather concerns will once again be
something to watch out for heading into the afternoon hours.
Afternoon highs will be primarily in the 70s, with a few 60s in
eastern Colorado.

Wednesday and Thursday, models show the low moving to the southeast,
back into Nebraska.  During this time, a few isolated showers or
thunderstorms may move through the northern portions of the area.
Additionally, there will be the potential for a few areas where
elevated to near-critical fire weather conditions may be possible.

Friday, flow transitions to northerly to northwesterly.  The pattern
is looking a little more active as a disturbance is expected to move
into the area over the weekend, bringing a chance for some rain.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1137 AM MDT Sun May 5 2024

MVFR conditions are expected for much of the afternoon and
evening timeframe at both terminals. Clouds continue to move
through the region today and into tomorrow as our next system
moves through. Breezy conditions will continue, with winds
increasing out of the south to southwest through the rest of
today. A boundary will move through the region tomorrow morning,
shifting winds to the west at KGLD by 16Z and KMCK by 18Z. A few
showers and isolated thunderstorms will be possible as the front
moves in. Due to uncertainty in initiation location of
showers/storms, have omitted a mention of these from prevailing
conditions for the time being.
