.DISCUSSION /Through Thursday/...
Issued at 1117 PM MST Thu Nov 5 2026

Lows tonight are forecast to be similar to the last few nights with
temperatures around freezing for the plains and in the upper teens
to 20s for the high country. The weak trough of interest for
Friday`s weather is over the western US at this hour and moving
towards Colorado, but it is forecast to split into two. Each
successive suite of model runs has trended the trough that is moving
closer to Colorado weaker and to the north of our area.
Consequently, the 18z and 00z short-term models have trended even
drier for our area. For our high country, the HRRR shows almost no
precipitation with the RRFS showing very light snow showers and
isolated coverage at best. Thus, light snow chances remain low (10-
20%) for locations above 8,500 feet on Friday afternoon and evening.
Any snow accumulation is forecast to be 1 inch or less with the vast
majority (> 80%) of the high country not seeing any accumulation.
Any precipitation will quickly end on Friday evening. Highs for the
plains on Friday afternoon are forecast to be near seasonal averages-
in the mid to upper 50s. Some light northeast winds and increased
cloud cover could lower temperatures a few degrees from the current
forecast.

For Saturday through at least the end of the forecast period,
ridging aloft builds in taking firm control of our weather. Above
average temperatures (but below records), mostly sunny skies, and
precipitation chances near zero continue to be expected for the week
ahead. The mid-level ridge looks strongest for our area on Sunday
and Monday with temperatures pushing 7 to 8 C at 700 mb. As noted
over the last few days, ensemble guidance shows high temperatures in
the mid to upper 60s for the urban corridor and highs approaching 70
F on the far eastern plains for those days. The other days this week
do still look to remain above average with highs generally in the
low to mid 60s on Saturday as well as Tuesday through at least
Thursday for the plains. The ridge could break down by the end of
next week into next weekend, but there is poor agreement on when
exactly this will take place at this time.

.AVIATION /06Z TAFS through 06Z Saturday/...
Issued at 1040 PM MST Thu Nov 5 2026

No aviation concerns, with only BKN high clouds above 12,000-15,000
ft AGL at the Denver area TAF sites. Light and fairly normal
diurnal wind patterns will persist with speeds generally 10 kts or
less. At KDEN, this means S-SW winds will prevail through about
16Z, then becoming light and variable 16Z-19Z. Winds then
attempt to turn light N-NE (60-70% chance) 19Z-00Z. Then expect a
return to light SE-S winds by 03Z Saturday.
