.DISCUSSION...Expect scattered showers and thunderstorms this
afternoon across the San Juan Mountains and along the central

lightning and gusty winds are the primary threats today. A dry 
airmass returns to the region tomorrow and on into the week with 
temperatures warming to 10-15 degrees above normal by Wednesday.
