209 AM MDT Mon Jul 24 2017

.SHORT TERM...(This evening through Monday)
Issued at 142 PM MDT Sun Jul 23 2017

Latest upper air data shows the ridge over the Central Rockies.
Water vapor imagery shows a very dry environment between the I-80
and I-70 corridors from the Rockies east into Central Nebraska and
Central Kansas.  At the surface a high pressure was moving east out
of the Tri-State Area.

Tonight will be similar to last night, although lows will not be
quite as cool due to some warm air advection occurring with the
south winds.

Monday will continue to be dry as the ridge builds over the Central
Plains and an upper level short wave trough tracks over the Northern
Plains. Highs will be warmer than today by a few degrees. Winds will
be breezy in the afternoon as breezy 850mb winds mix to the ground.

.LONG TERM...(Tuesday through Sunday)
Issued at 208 AM MDT Mon Jul 24 2017

In the extended period the models are showing the upper level ridge
amplifying over the western U.S. This will produce an strong
northwesterly flow over the region. Towards the end of the period
the models differ significantly. With the ECNWF and NAVGEN maintain
the northwesterly flow while the GFS shows a sharper ridge axis
creating a north-northeasterly upper level flow over the region.

Regardless of how the upper level flow turns out towards the end of
the period, look for shortwave troughs to move within the flow
pattern and produce chance of showers and thunderstorms each

Temperatures look to be slightly below normal for the period.
