.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 210 PM MDT Tue Jun 18 2024
Tonight...showers and thunderstorms will gradually increase in
coverage as they spread northwestward with the highest pops (50%-80%
generally across all but Yuma and Dundy counties. NAM 250mb jet
divergence favors areas generally south of I-70 for higher rainfall
totals after midnight which is also where PWAT values are highest,
around 1.4-1.6 inches and closer to the stalled frontal boundary.
The inherited Flood Watch looks good. Not sure (based on DESI) that
a few locations could see 4 inches of rain but general 1 to 2 with
localized 3 inch amounts are reasonable. Low temperatures are
forecast to be in the lower 50s to near 60.
Wednesday-Wednesday night...widespread low cloud cover will be over
the area through the period. Morning rain showers should become less
likely through the day as dry air aloft moves in from the
south/southwest and moisture below 700mb moves toward the north.
Presently, 30%-70% pops in the morning decrease to around 30% in the
afternoon and that could be generous. Overnight, it appears another
weather system moves through from south to north, supporting 50%-60%
pops. Overall qpf values are pretty low with a few hundredths to
tenth of an inch possible.
With the widespread cloud cover and wedge of cooler air aloft, have
lower high temperatures into the upper 50s to lower 60s in far
eastern Colorado with lower to upper 60s elsewhere. Further
adjustments will likely be needed, possibly lowering highs if the
NAM verifies which is quite possible. Low temperatures are forecast
to be in the lower 50s to lower 60s.
Thursday-Thursday night...drier air in the 850-500mb layer quickly
overtakes the area by mid to late morning, ending any precipitation
chances (currently at 20% in the morning). Generally dry conditions
continue overnight. Southerly winds strengthen during the day with
gusts of 25 to 40 mph, highest west of Highway 27. Breezy to windy
southerly winds continue overnight, mainly west of Highway 27. High
temperatures rise back into the middle 80s with low temperatures in
the lower to upper 60s.
Friday-Friday night...a monsoonal type pattern sets up with an upper
trough to our west and ridge centered over the southeast states.
This pattern funnels moisture into the area from the south.
Presently, there are varying solutions as to just how much moisture
reaches the area with the NAM more optimistic compared to the GFS
and ECMWF. As a result, the forecast is generally dry for now. High
temperatures are currently forecast to be in the middle 80s to lower
90s with low temperatures in the lower 60s to middle 70s. It will
continue to be windy with southerly winds gusting to 45 mph during
the day, slowly decreasing overnight.

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Issued at 105 PM MDT Tue Jun 18 2024
Into the weekend, flow aloft veers towards the west-northwest as
troughing slides east and high pressure stretches across the
southern CONUS. Weak waves moving through the flow will allow for
slight chance (generally around 15-20%) afternoon-evening
showers/storms each day.
For temperatures, the gradual warming trend continues with low-mid
90s over the weekend followed by possible return of triple digit
heat by the start of the work week. Low temperatures are forecast to
be generally in the 60s to perhaps a few low 70s east.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1100 AM MDT Tue Jun 18 2024
KGLD...VFR conditions are expected from taf issuance through
about 08z. Northerly winds gusting to 30kts at taf issuance will
continue this afternoon before veering to the northeast around

expected as stratus expands across the area. Rain showers and
perhaps a few thunderstorms will be possible along with some
light reductions in visibility due to mist (BR). Winds will
remain from the northeast around 15kts with perhaps some higher
gusts.
KMCK...VFR conditions are expected from taf issuance through
about 11z. Northerly winds gusting to 30kts at taf issuance will
continue this afternoon before veering to the northeast around

stratus expands across the area. Rain showers and perhaps a few
thunderstorms will be possible along with some light reductions
in visibility due to mist (BR). Winds will remain from the

Generally, 1 to 2 inches of rainfall is expected with localized amounts perhaps up to 3 inches. As a result, a Flood Watch for flash flooding has been issued through Wednesday morning. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY...

...A STRONG THUNDERSTORM WILL IMPACT SOUTHEASTERN GRAHAM COUNTY
THROUGH 300 PM CDT...
At 224 PM CDT, Doppler radar was tracking a strong thunderstorm
capable of producing a landspout over Palco, or 16 miles southeast of
Hill City, moving northeast at 60 mph.
HAZARD...Landspout tornadoes, wind gusts up to 40 mph, and half inch
hail.
SOURCE...Radar indicated.
IMPACT...Minor damage to outdoor objects is possible. Gusty winds
could knock down tree limbs and blow around unsecured
objects.
This storm will remain over mainly rural areas of southeastern Graham
County.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
If outdoors, consider seeking shelter inside a building.
Landspout tornadoes can form with a developing thunderstorm before
rain, hail, and even thunder is observed. Landspout tornadoes are not
usually associated with a wall cloud and are often difficult to
detect with weather radar.
