SHORT TERM /THROUGH TONIGHT/

Issued at 104 PM MDT Fri Jun 19 2026

Rest of today...

SPC continues marginal risk over region mainly over far eastern plains for hail and gusty winds. Cant rule out a non svr storm or two over the I-25 corridor region later this afternoon/early evening. Gusty winds and isold CGs main issue.

Tomorrow....

Significant severe weather is expected over the eastern plains tomorrow. SPC has area outlooked for large damaging hail, significant damaging wind gusts and a low end threat for tornado activity. Thunderstorm potential will be dependent on how far west the moisture can make it back towards the mtns. At this time the greatest threat for the strongest storms will be over the far eastern plains. A review of the HREF guidance shows quite a few rotating storms over the far eastern plains of Colorado with hodographs favoring supercell activity.

The other concern tomorrow will be the fire weather concern. Red Flag conditions will be prevalent over all of the mtns and valleys and the western 1/3rd of the plains. RH values will be in the single digits in the above mentioned locations and winds will be gusty 20 to 30 knts plains and 30 to 45 knts mtns and valleys. Strongest winds look to be over the San Luis Valley and the Sangre De Cristo mtns.

Otherwise, it will be hot again over the entire region. 100F values will occur along the lower ark rvr valleys from Pueblo east to the KS border. 90s elsewhere over the plains, and 80s to around 90F valleys.

LONG TERM /SATURDAY THROUGH FRIDAY/

Issued at 104 PM MDT Fri Jun 19 2026

Sunday will be mainly dry. Elevated fire weather concerns will cover most of the region again. Any thunderstorms will be mainly well north of US50 along the Palmer Divide. It will be hot once again, but not as hot as tomorrow.

From Monday into late week...

We could see several rounds of strong to severe storms over the plains during this period. A favorable upslope pattern will develop ans several mid level disturbances in the northwesterly flow aloft will move over the region. Shear and CAPE will be favorable for rotating storms, and expect we may see a few days of severe storms over the plains. With the NW flow, any supercells that develop will have a tendency to turn to the right of the mean flow and this may put the urban corridor cities under the gun for severe storms during this period.

Over the interior mtns and valleys, it will remain hot and dry. Winds will likely be strong enough to warrant red flag conditions and expect we may see several days of fire weather highlights over the higher terrain this upcoming week.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 607 PM MDT Fri Jun 19 2026

Convection this afternoon has been minimal north of the Highway 50 Corridor, with the best coverage south of Highway 50. Convection winds down through the rest of the evening, with VFR conditions expected at COS, PUB and ALS over the next 24 hours. Winds have been varying from the east to northeast at COS and PUB through the afternoon, and look to become generally light diurnal overnight, before becoming gusty south southwest aft 18Z tomorrow. Generally light winds at ALS into the overnight hours, with gusty southwest winds also developing aft 18Z Sat.

FIRE WEATHER

Issued at 104 PM MDT Fri Jun 19 2026

Tomorrow... Critical conditions become much more widespread as stronger west-southwest winds move in across the higher terrain. Temperatures will increase across the area, and RH values will dive into the single digits in the afternoon across portions of the mountains and high valleys. A RED FLAG WARNING has been issued including all of the higher terrain and valleys as well as portions of the plains due to gap flow and dry, downsloping winds.

Sunday Onwards: Dry, warm conditions will last throughout most of next week. Critical conditions are expected each day across the higher terrain, with low RH values and frequently gusty winds during the afternoons. At this time, no precipitation is expected over the mountains this week.
