.DISCUSSION...(This Evening Through Saturday)
Issued at 146 PM MDT Sat Sep 6 2025
Current Water Vapor and upper air models show northwest flow over
the FA, with upper ridge situated over the Rockies. Surface
analysis depicts high pressure over the Dakotas. Winds are
relatively light and variable across the region this afternoon,
with clear skies and temperatures in the upper 60s and 70s. Cool
conditions continue tonight, with lows expected in the upper 30s
to mid 40s.
Upper ridge slides eastward over the northern and central planes
the remainder of the weekend. This will result in a warming trend
through monday, with highs climbing back into widespread 80s by
Monday. Daytime mixing will result in breezy southeast winds Sunday
afternoon, however gusts will only be in the 20 to 30 mph range. Expect
mostly sunny to partly cloudy skies through middle of next week
with dry conditions as ridge dominates the area. Temperatures
turn more seasonal and chances for precipitation increase towards
the end of next week, as upper low digs into the western CONUS,
pushing the upper ridge east of the forecast area.
