.DISCUSSION...
Issued at 132 PM CDT Sat Sep 27 2025
A fairly stagnant pattern prevails through the weekend resulting in
multiple days without significant changes. Broad mid to upper level
ridging remains the dominant weather feature over our area with a
closed upper low remaining over Baja California. At the surface, we
are currently in a pressure col as a weak cold front approaches our
northwestern doorstep. Today, highs will range in the low to mid 80s
with areas farther north on the lower end of that range. Late
tonight into Sunday, the weak cold front is anticipated to begin
moving through the northern half of our CWA before stalling out
somewhere north of I-70 late tomorrow morning as it becomes more
diffuse. Due to its limited strength and being so distanced from the
parent low, it is not expected to have much impact on the area.
Going into Sunday afternoon, the whole pattern shifts slightly to
the east with a stout mid to upper trough over the Pacific Coast
helping move things along. As the mid to upper level ridge axis
moves through the area, expect Sunday highs to be slightly warmer
than today. Highs for Sunday are anticipated to range in the mid to
upper 80s which happens to be 8-12 degrees above normal. There is
some uncertainty with temperatures as the stalled cold front could
keep areas north of I-70 in the low to mid 80s.
For the start of next week, the mid to upper level trough over the
Pacific Coast pushes the closed low over Baja California back into
the flow as it weakens. It is anticipated to track to the
north/northeast staying well to the west of our area, staving off
any chances for precip through the start of next week. This trough
over the Pacific Coast also amplifies the ridge helping it maintain
its influence over our area. As a result, highs for most of next
week stay above normal ranging in the low to mid 80s. Late next week
as the trough over the Pacific Coast makes landfall in the northwest
U.S., models begin to diverge on solutions. For now, it seems precip
chances return sometime late next week with the approaching mid to
upper level trough moving through the Great Plains.
