.DISCUSSION /Through Saturday/...
Issued at 222 PM MDT Sat Jul 5 2025
Scattered storms have formed across our CWA this afternoon and
have been sub-severe so far. Instability is modest with surface-
based CAPE values around 1,000 j/kg. Deep layer shear is rather
low with values generally around 25 knots. The main concern with
storms that form this afternoon and evening will be strong wind
gusts due to steep lapse rates and large dew point depressions in
the boundary layer. However, DCAPE values are around 1,400 j/kg
which suggests most downdrafts will be capable of gusts up to 50
mph and not necessarily severe gusts of 60 mph. We have
collaborated with SPC and we are in agreement that no Severe
Thunderstorm Watch will be needed at the time of this writing. If
a more organized MCS were to form, then a watch may be needed.
On Sunday, there is a decent chance that an outflow boundary from
overnight convection in Nebraska will keep easterly winds over
northeast Colorado for much of the morning and afternoon. This
would advect much better dew points into our area which would
lead to higher instability. In addition, the low level easterly
winds would increase deep layer shear. All factors seem to be
pointing towards Sunday having a much better severe weather threat
than Saturday with large hail and damaging wind gusts expected out
of strong storms over the I-25 corridor and eastern plains.
On Monday, conditions will be very similar to Sunday. Healthy dew
points should stay in our area across northeast Colorado. If that
is the case, another day of strong to severe storms with large
hail and damaging wind gusts will occur.
We break the pattern of daily strong to severe storms on Tuesday
as ridging strengthens aloft with more capped conditions. We will
then begin talking about heat on Wednesday as a 597dm 500 mb high
will form over our forecast area. With strong subsidence and
little cloud cover, temperatures will have the chance to get to
the upper 90s and around 100 degrees across the plains. GFS MOS
has 101 for Denver and the ECMWF ensembles have roughly half the
members at 100 or above. If these warmer solutions appear more and
more likely in the coming days, a Heat Advisory may be needed.
There is a good deal of uncertainty with Thursday`s forecast as a
trough will be quickly approaching from the west. If the trough is
quicker to move through, cooler temperatures near seasonal normals
can be expected with scattered storms. However, if the trough is
slow to move through, another very hot day with temperatures near
100 degrees across the plains is possible.

.AVIATION /18Z TAFS through 18Z Sunday/...
Issued at 1136 AM MDT Sat Jul 5 2025
VFR conditions expected through the TAF period. The main concern
today will be strong outflow wind gusts from nearby storms. High
DCAPE values, steep lapse rates, and dry conditions near the
surface could lead to gusty winds developing. The wind gusts in
the PROB30 for this afternoon were increased to 35 knots and gusts
could potentially reach 40 knots. Otherwise, a direct impact from
a storm could lower ceilings down to 6,000 feet and could lower
visibility down to 3 miles in the worst case scenario.
Tonight, normal drainage winds are expected. Light northwest
winds will develop in the morning hours on Sunday at BJC and DEN.
Tomorrow will be a repeat of today in terms of thunderstorm risk
and potential impacts. The primary concern will be strong wind
gusts again.
