.DISCUSSION...
Issued at 130 AM MDT Mon Sep 23 2024

The first full day of fall will see pleasant weather across the
Cowboy State. Temperatures are forecast to be just around seasonable
values today. Highs across areas east of the Divide will be in the
low to mid 70s while west of the Divide sees values in the upper
60s. A weak cold front will push through the region as a shortwave
moves over parts of Montana. The front looks dry with the only
impact being a period of breezy winds during the afternoon.
Winds will gust around 15 to 25 mph at times as the front moves
through during the afternoon/evening, by sunset winds will
diminish becoming light through the overnight.

Quiet weather is expected to prevail throughout the remainder of the
week as an area of ridging builds across much of the Western CONUS.
Temperatures are forecast to warm up with above normal values
expected for the second half of the week. Some models are showing
high temperatures Wednesday-Friday reaching the mid to even upper
80s east of the Divide and upper 70s west of the Divide. Based off
current forecasted highs some locations may be within a few degrees
of record high values. Ridging looks to persist across the region
well into next weekend keeping any disturbances well to the north of
the area. Unless models begin to shift, conditions are looking warm
and dry as we near the end of September.
