.DISCUSSION /Through Sunday/...
Issued at 200 PM MDT Sun Jun 8 2025

In the near term, stratus was gradually beginning to thin out from
Denver southward but will holding steady in the nrn foothills and
nrn portions of the I-25 Corridor.  As a result, best heating has
been across the srn foothills and over the higher terrain.  Still
expect sct showers and storms in these areas with reduced coverage
where less heating has occurred.  Over the plains, expect little
activity into the evening hours except possibly over the Palmer
Divide.

On Mon, drier air will spread across most of the area in NNW flow
aloft.  There will be enough lingering moisture along and south of
the I-70 mountain corridor into South Park to allow for a chc of
aftn showers/storms.  Elsewhere expect dry conditions.  Highs on Mon
will be warmer with readings in the upper 70s to lower 80s across
the plains.

For Tue thru Wed the flow aloft will weaken and become light
westerly.  Overall, don`t see much moisture on Tue with a slight
increase on Wed.  Tstm activity will be rather isold and confined to
the higher terrain on Tue with a slight increase expected on Wed.
Temps will continue to rise with readings in the upper 80s to lower
90s over nern CO.

Looking ahead to Thu and Fri, the flow aloft will still be rather
weak with some moisture embedded in the flow.  Thus will keep in a
chc of showers and storms over the higher terrain with a slight chc
across the plains.  Highs will remain above normal with readings in
the upper 80s to lower 90s across the plains.

.AVIATION /00Z TAFS through 00Z Tuesday/...
Issued at 708 PM MDT Sun Jun 8 2025

There is some weak convection around, but I will just keep VCSH
going at DIA through 03Z. There could still be a SCT-BKN050-070
cloud deck through mid/late evening, otherwise no ceiling issues.
Wind directions will be a bit squirrelly until the convection
ends. Will go weak normal drainage patterns overnight.
