.DISCUSSION...
Issued at 522 PM MDT Sun Mar 15 2026

TODAY: Cooler and Windy

Northwest flow is ushering in a cooler airmass today in the
wake of last night`s cold front. Breezy conditons remain in
place until sunset this evening, but most locations will see
lighter winds compared to yesterday. The southern valleys are
the exception and will continue to see wind gusts up to 55 mph
in this post-frontal regime. Therefore, a Wind Advisory remains
in place until 8 PM this evening.

TONIGHT: Frost/Freeze for Lower Valleys

It`s still looking quite chilly tonight as very dry air settles
in over the area and winds begin to settle down with a relaxing
gradient aloft. Lows in the low 20s to low 30s are still the
highly probable (>70% chance) across the lower valleys, so
anyone with concerns of tender vegetation should take
precautions. Increasing cloud cover as the night wears on could
slow down radiational cooling and moderate temperatures some,
but it may be too little too late to prevent a hard freeze.

THIS WEEK: Hot and Dry

A sizable ridge builds over the western CONUS this week
resulting in a rapid return to unseasonably warm conditions.
Record-setting high temperatures are possible Wednesday through
next weekend with strong southwesterly flow keeping the region
warm and dry.

As we transition into this pattern over the next 48 hours,
light snow cannot be ruled out over the northern Divide
mountains. An inch or two may fall above timberline Monday
night, but impacts look minimal at this time.
