.SHORT TERM...(Today and tonight)
Issued at 510 AM MDT Sun Jun 25 2017

Currently...

Quite a bit of mid cloudiness was located east of the contdvd this
morning. These clouds are associated with persistent modest upslope
flow combined with weak short waves in the  mid level northwest flow
aloft. Clusters of showers and isold tsra were noted mainly north,
east and south of the fcst area, although a few showers were noted
in the KTAD region. Temps were mild at 3 am, with 50s and 60s in the
valleys and plains, and 30s and 40s in the mtns. Dewpts were
relatively high with 40s in the valleys and 50s most of the plains.

Today...

Short range hires guidance has been having problems this morning as
it has been over forecasting  precip over the plains during the last
several hours. Given latest trends, believe best chance of precip
over the fcst area will be over the far eastern plains and along the
CO/NM border, and this is where I painted the highest pops for this
morning. By this afternoon, as another weak short wave moves towards
the region, showers should initiate over the S mtns and move
southeast later this afternoon. Some shear and CAPE are present, so
a few stonger cells will be possible, mainly along the greater I-25
corridor from Pueblo south to the NM border. Max temps today over
the plains should be about 2-4F warmer than yesterdays highs.

Plains will likely see quite a bit of mid lvl cloudiness today.

Any precip over the higher terrain (w of the s mtns) will be
isolated.

Tonight...

With weak waves continuing to move southeast in the NW flow
aloft, showers and tsra will be possible this evening and
continuing into the early morning hours. The best overall coverage
will be this evening. Mountains for the most part will remain
dry, especially west of the s mtns. \/Hodanish

.LONG TERM...(Monday through Saturday)
Issued at 510 AM MDT Sun Jun 25 2017

Main longer term meteorological issues continue to be relatively
active conditions in combination with generally near to below
seasonal temperatures into Monday night as a passing upper
disturbance interacts with the daily heating cycle and adequate
atmospheric moisture/surface boundaries.

The highest potential for strong to marginally severe thunderstorms
as well as cells containing locally heavy rain should noted along
and near the I-25 corridor from Monday into Monday night(which
matches well with the Storm Prediction Center's latest Day 2
Severe Outlook).

Overall, it still appears that return to drier(although isolated
storms will be possible at times) and warmer conditions should be
noted from Tuesday night into late week as varying degrees of
eastern Colorado lee-side surface troughing tends to dry the
airmass over the majority of the forecast district.

Also, a brief-lived northerly-northeasterly surface surge is
projected to move across eastern sections of the forecast district
Thursday night, allowing for cooler maximum temperatures on
Friday in combination with somewhat enhanced precipitation
potential from Thursday evening into Friday night.

Coolest temperatures during the longer term over the forecast
district are anticipated Monday and then again on Friday with
warmest conditions expected Tuesday and Wednesday and then again
on Saturday with maximum temperatures nearing or exceeding the 90F
threshold over eastern portions each of these days.
