.KEY MESSAGES...

- Dense fog will affect portions of the area this morning,
  mainly in northwest Kansas. This includes the Interstate 70
  corridor between Kanorado and Oakley. Dense fog may be
  intermittent in nature. Fog will lift and dissipate after
  sunrise.

- Severe thunderstorms are possible this afternoon and evening,
  mainly along and south of a line from Yuma County to Gove
  County between 3-10 PM MDT. Large hail and damaging winds
  appear to be the primary threats. A brief, isolated tornado is
  possible. Locations south of Highway 40 are most at-risk.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 150 AM MDT Fri Jun 6 2025

Through Sunrise: Fog has developed over much of northwest
Kansas this morning. As of 07 UTC, dense fog has been observed
at several ASOS/AWOS sites (Wray, Goodland, St. Francis, Colby).
Regional satellite, radar and observational data indicate that
upstream cloud cover (mid-upper level ceilings in Colorado) and
patchy sprinkles will progress eastward over northwest Kansas
this morning.. lending considerable uncertainty to dense fog
coverage and duration. With this in mind.. have opted to message
fog via social media / weather story and hazardous weather
outlook (in lieu of a Dense Fog Advisory).

Today-Tonight: A WSW flow aloft regime will persist over the
region. In contrast to yesterday, a southwest to northeast
oriented shear axis -- extending southwestward from Manitoba to
Montana and Idaho at 07 UTC this morning -- will slowly progress
east toward the Northern Plains late this afternoon and evening.
While upper level forcing directly associated with this feature
will remain well upstream of the Goodland county warning area
during peak heating, upstream convective development associated
with this feature.. and/or small amplitude waves rounding it`s
eastern periphery (amidst strengthening WSW flow aloft in the
lee of the central Rockies).. could certainly influence
convective development/evolution in the Goodland CWA. Morning
fog and lingering stratus over northwest Kansas are likely to
influence environmental conditions this afternoon.. lending
additional uncertainty to convective development and evolution
this aft-eve. Severe thunderstorms are possible, mainly along
and south of a line from Yuma County to Gove County between
21-04 UTC (3-10 PM MDT). Isolated supercells are possible..
mainly south of I-70. Large hail and damaging winds appear to be
the primary threats. While a brief, isolated tornado is a
possibility with any discrete supercells.. weak low-level flow
may mitigate tornado potential in the Goodland CWA. Locations
south of Highway 40 are most at-risk.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 1223 PM MDT Thu Jun 5 2025

Saturday, ridging begins to develop across the western CONUS
which will be the start of a warming trend for the area as high
temperatures are currently forecast to rebound in to the mid 80s
across the area. The forecast for the most part is dry for
Saturday but there is a 10-20% chance Norton and Graham county
may get skirted with a passing shower as a weak disturbance
moves across north central Kansas.

Sunday at this time appears to be a bit more active as a low
pressure system develops across the northern Plains which moves
a cold front back through the area. Showers and storms are
currently forecast to develop along the front with severe
weather possible during the afternoon and evening hours. There
does remain some discrepancies with the overall placement of the
low and timing of the front. A slower cold frontal passage
would support an increased severe weather potential for the
area.

Into the start of the next week, we remain in the NW flow
pattern but not seeing any indications at this time of any
disturbances in the flow so the forecast will remain dry for
now. High temperatures are forecast to remain in the upper 70s
to low 80s across much of the area. Troughing then does look to
return towards the middle portion of the week with the potential
for our active pattern to continue with severe weather chances
possible.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1200 AM MDT Fri Jun 6 2025

IFR to VLIFR conditions associated with low stratus and/or
dense fog will prevail through sunrise this morning. Expect
conditions to improve to MVFR (GLD) or VFR (MCK) during the late
morning and early afternoon. While showers and thunderstorms
are possible at both terminals during the late afternoon and
evening.. the GLD terminal is more likely to be affected.
