.SHORT TERM...(This evening through Tuesday)
Issued at 302 PM MDT Mon Jun 19 2017

A west-northwest flow aloft will prevail around a strong upper
level ridge over the Desert Southwest through Tuesday. Somewhat
cooler air at the surface is producing highs in the lower to mid
80s today. The warm air aloft is capping convection this
afternoon. The airmass warms Tuesday with highs in the mid 90s
across northeast Colorado. May be enough moisture and instability
for a few weak showers and storms over the higher terrain. Low
levels remain dry over the Front Range and eastern plains, so just
expected mid and high cloud off the higher terrain.


.LONG TERM...(Tuesday night through Monday)
Issued at 302 PM MDT Mon Jun 19 2017

Broad high pressure aloft will be over Arizona and New Mexico on
Wednesday and Thursday with a light west to northwest flow aloft.
Temperatures will climb into the lower to mid 90s across lower
elevations on Wednesday. A weak front on Thursday may cool us off
a few degrees with some shallow upslope flow this in the
afternoon with a slightly better chance for showers and
thunderstorms.  A stronger cold front expected to move over
Eastern Colorado on Friday with much cooler temperatures. This
cooler air would also bring a more stable airmass so any showers
or storms would be confined to the mountains and higher terrain.
Colorado will be under a stronger northwest flow pattern through
the weekend with continue temperatures below normal and slight
chances of afternoon/evening thunderstorms.

20 knots.
