Issued at 224 AM MST Wed Feb 15 2017

Mild and dry weather will continue through the end of the week
into the weekend. Upper ridging will continue through the
weekend...however with the main axis pushing east of the region,
southwesterly flow aloft will develop. Despite this more active
flow...models continue to show agreement on a drier solution
toward the start of the work week with split flow developing, so
have dropped pops to slight chance. Above average temps are also
expected to continue through early next week.
