.DISCUSSION /Through Thursday/...
Issued at 220 PM MDT Thu Jun 26 2025
Water vapor satellite shows dry air over Colorado with southwest
flow aloft. There is some weak subsidence that is limiting
convection this afternoon. However, a few stray storms are forming
over the Palmer Divide and east to northern Lincoln County. High
resolution models are also starting to come into better agreement
that showers will form over the foothills late this afternoon and
into the evening and these showers will move over the I-25
corridor this evening. Brief moderate rain with gusty winds will
be possible with these showers. PoPs were increased to get a
mention of showers in the forecast this evening.
Temperatures aloft will increase on Friday as light zonal flow
aloft will be in place. This will allow high temperatures to the
reach the low 90s across the I-25 corridor and plains. Model
guidance also suggests a weak low level convergent boundary will
form generally from Deer Trail to Julesburg. Isolated storms will
form along this boundary by the late afternoon. Soundings show a
large boundary layer up to around 600 mb with dry adiabatic lapse
rates. This suggests strong wind gusts up to 60 mph will be
possible with the strongest storms especially north and east of
Akron. Elsewhere, a few light showers and weak storms could form
over the higher terrain and move onto the adjacent plains.
Saturday will be very similar to Friday as hot temperatures and
isolated storms will again be possible. Gusty winds will be the
main threat from these storms.
A cold front seems likely to move through the northeast plains on
Sunday bringing northeast winds. The majority of guidance
indicates dew points may be in the 60s and upper 50s behind this
front. Given the upslope winds and moderate instability, it is
expected that storm coverage will increase with 30-40% coverage.
An upper level jet will pass to the north of Colorado on Sunday
and may help to increase the deep layer shear close to the WY/CO
and NE/CO borders. Some storms may be strong to severe in far
northern Colorado with large hail and damaging wind gusts the
primary threat.
Monday will have east-southeast winds across the plains with
healthy dew points. Moderate instability will be under a strong
cap due to a ridge and warm temperatures aloft. The upslope flow
may help to generate storms in the foothills but it is uncertain
if the storms will be able to survive on the plains. Monday will
be the coolest day of the 7 day forecast.
A ridge aloft will strengthen on Tuesday and Wednesday and highs
will increase to normal. Isolated storms will likely develop over
the higher terrain each day.

.AVIATION /00Z TAFS through 00Z Saturday/...
Issued at 534 PM MDT Thu Jun 26 2025
VFR conditions expected through the TAF period. Southeasterly
winds will gradually turn to southerly drainage through the
evening, generally remaining near or below 10 kts. There`s a small
chance (~20%) of isolated high-based showers developing over the
Denver metro mid-evening. Confidence is not high enough to include
more than VCSH in the TAFs at this time. Any convection would
likely be on the weaker side. Light winds will prevail tomorrow
morning with prevailing flow becoming southeasterly entering the
afternoon. Weak high-based convection could occur after ~22Z Fri
but coverage is likely to be spotty and intensity very weak.
