.DISCUSSION /Through Wednesday/...
Issued at 1120 PM MDT Wed May 6 2026

Back to our regularly scheduled programming. Sub-freezing
temperatures are anything but uniform currently and that`ll
continue to be the case through sunrise, especially for the I-25
corridor where fingers of downslope winds will persist. The
Freeze Warning will be maintained for now, as the majority of the
plains, and some patchy urban corridor locations will remain below
freezing through the early morning hours. Later today, rising
heights under northwest flow aloft will allow temperatures to
return to near seasonal averages. During the latter half of the
day, a subtle shortwave will zip over northeast Colorado, and
bring isolated to scattered high- based showers late afternoon
into the evening hours for the mountains and the northern plains.
Most other areas, including the urban corridor, will largely remain
dry.

The high country will warm farther into Friday, while temperatures
look to stabilize for the lower elevations. Moisture aloft will be
limited and thus all areas should remain dry.

Another shortwave is slated to traverse the region Saturday,
along with a weakening front and advection of higher dewpoints
into the plains in the late afternoon and evening. This will bring
a shot at scattered showers in the late afternoon and evening and
perhaps accompanied by a few thunderstorms with lingering marginal
ML CAPE. More notably, pre-frontal winds will be hefty in the high
country with gusts 35-50 mph, and breezy conditions will extend
into the lower elevations as well were gusts may approach 40 mph.

Our area will dry back out by Sunday as the warming trend is
reinforced and temperatures climb into the 70`s. Upper-level
ridging will inch closer next week and keep us in a dry and
subsident pattern, leading to considerably warmer temperatures (in
the 80`s) during the week. Monday looks warmest at this time, when
highs could approach 90F for the warmest plains and I-25 corridor
locations.

.AVIATION /06Z TAFS through 06Z Friday/...
Issued at 1120 PM MDT Wed May 6 2026

VFR conditions are expected to prevail for all terminals through
the TAF period, although FEW-SCT clouds with bases 040-060 do
appear possible later this evening behind a decaying frontal
boundary.

Current drainage winds will remain in the place through mid-
morning today (W for KBJC), rotating to the W then NW by 17Z. Come
early afternoon, breezier NW winds with gusts 20-25 kts look to
mix down, especially for KBJC/KDEN. The aforementioned boundary
will approach the Denver area mid evening, but will be washing out
as it does so. There`s around a 50/50 chance for a transition to
NE flow around 03Z with this boundary, particularly for KDEN/KBJC,
but if that occurs, speeds should be light. Given the uncertainty
in direction, VRB06KT is included in the TAFs.
