...FLASH FLOOD THREAT INCREASING AGAIN FOR THIS AFTERNOON AND
EVENING...

12Z Denver sounding showed Precipitable Water (PW) had risen to
1.20 inches, although there was some drying between 3,000 and
7,000 feet AGL due to a light westerly downslope component, likely
the result of the passing of the Mesoscale Convective Vortex (MCV)
into northeast Colorado. This feature continues to move slowly
northeast, and thus the westerly component (and even weak
subsidence) should begin to weaken over the next few hours with a
subsequent moistening and nearly moist adiabatic profile through
this afternoon. In fact, KFTG wind profile shows a slow transition
to a deep north/northeast flow up to 7,000 ft (12K MSL). This
will be the trend through the afternoon hours.

We're already seeing cumulus develop with limited breaks in the
clouds and solar insolation. Forecast soundings suggest lower 70s
will be sufficient to get deep convection going again, and it
won't take much in this warm/moist environment to produce heavy
rainfall. Skinny CAPE profile, a deep warm cloud depth of
7000-8000 ft, high PW (near 99th percentile), and slow storm
motion once again. In this environment, stronger storms will be
capable of producing 1.5 to 2.5 inches of rain in less than an
hour, and there are threat of repeating showers/storms as well for
locally heavy rain. Per latest short range data and the expected
weak northeasterly push, expect the showers/storms to focus
in/near the Front Range Mountains and Foothills, and Palmer
Divide. That's where the highest threat of flash flooding will
occur today. Areas east and northeast of Denver will have a lower,
but non zero threat, with a slightly more stable environment
potentially capping things off.

&&

.SHORT TERM...(Today and tonight)
Issued at 402 AM MDT Sat Jul 31 2021

Today and tonight, another round of thunderstorms producing heavy
rainfall and flash flooding is expected from the urban corridor
westward into the Front Range, and likely impacting the burn scars
once again.  This morning has remained fairly active.  An MCV did
develop last evening, and helped fire off some very strong
thunderstorms with heavy rain north and northeast of Denver
overnight.  Strong thunderstorms continue over Sedgwick and Phillips
counties at this time. SPC mesoanalysis still shows MUCAPE values
up to 1000 j/kg at this hour in the northeast corner. Models
still show showers and thunderstorms redeveloping late this
morning along especially along the Palmer Divide and Front Range
this afternoon and evening. Very high PWAT values 1-1.3 inches and
slow storm motions will continue to elevate the flash flood
threat. A cold front will help focus the convergence along
foothills and Palmer Divide this afternoon. The coverage will be
highest from the urban corridor westward. Strong outflow wind
gusts 40-50 mph also possible with the storms. High temperatures
this afternoon will be nearly 15 degrees cooler than yesterday.
Tonight the showers and storms should wrap up sooner, with much of
the activity ending or shifting south of the forecast area by
late this evening.

.LONG TERM...(Sunday through Friday)
Issued at 402 AM MDT Sat Jul 31 2021

The main concern for the period is the continued threat for heavy
rain through early next week. Above average moisture coupled with
weak flow aloft support the potential for slow moving thunderstorms
capable of localized heavy rainfall. Main threat will remain over
the higher elevations, especially over the already sensitive burn
areas. The overall threat decreases starting mid-week, as ensemble
guidance indicates a slight drying trend.

Sunday...

Some hi-res guidance indicates the potential for lingering
showers into Sunday morning, mostly over the southern portion of
the mountains/foothills. Moisture remaining in the region should
support that. Ensemble guidance indicates a gradual decrease in
above normal precipitable water values throughout the day Sunday.
However, these values are still in favorable ranges to support
shower/thunderstorms likely with lower coverage than the previous
few days. The better chances being more south and over the higher
elevations where the more favorable moisture and sufficient
instability is. The uncertainty lies in the amount of instability
that will exist over the region. The environment may be cooler and
more stable which would inhibit convection. Overall, given the
higher precipitable water values and weak winds aloft, heavy
localized rainfall is still a concern.

Monday through Wednesday...

On Monday, there is a signal for above normal moisture to stay in
the region resulting in potential for heavy rainfall. The upper
level ridge axis stays to the west with a shortwave trough
approaching from the west. Precipitable water values remain above
average; however, there's a bit more of a spread among guidance in
regards to if there will be enough instability. Higher chances will
likely be over the higher elevations where there is better moisture
and instability. Similar potential for showers and storms with heavy
rainfall exists for Tuesday as weak winds aloft may promote slow
storm motions. Ensemble guidance hints at the passage of a shortwave
trough which may allow for some additional forcing for scattered showers
and thunderstorms. Specific humidities ranging from 4-6 g/kg with
precipitable water values up to 1.0" which are in sufficient
ranges to support storms capable of localized heavy rainfall.

Wednesday through Friday...

A warming trend in temperatures is expected starting mid-week.
Temperatures will approach values in the 90s by the end of the work
week. The upper level ridge axis remains to the west of Colorado
Wednesday and Thursday. With ensemble guidance indicating some
residual moisture through the week, there are chances for
afternoon showers and thunderstorms; however, they will be less
coverage. The signal for moisture under the ridge isn't strong enough
to consider heavy rain potential at this point.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1014 AM MDT Sat Jul 31 2021

Showers and thunderstorms will develop in the area by 18Z and
become more numerous this afternoon. The most likely time for
these affecting the Front Range airports including KDEN would be
20Z-02Z. Some visibility and ceiling restriction expected with
locally heavy rainfall, so if a stronger storm moves over an
airport potential for visibility to briefly drop to 1SM with
ceilings around a thousand feet, along with gusty variable winds
to around 30 knots. Showers and storms expected to diminish/end by
or shortly after 02Z, with partial clearing. However, still some
potential for an MVFR stratus deck to develop at times through the
night. Light north/northeast winds expected to hold outside of
showers/storms today, then light southerly flow expected to return
toward 02Z-04Z.

&&

.HYDROLOGY...
Issued at 1014 AM MDT Sat Jul 31 2021

The threat of flash flooding will return by late morning/early
afternoon and then continue through at least early evening. The
Flash Flood Watch remains in effect through 9 pm. Storm coverage
will remain high with increasing moisture, and intensity of the
storms will be strong with increasing rainfall efficiency,
especially from the I-25 corridor west into the high country.
Rainfall rates of 1.5 to 2.5 inches in less than one hour can
again be expected with the stronger storms. Repeated rounds could
provide additional rain and heavier storm totals. Deepening
upslope following a weak northeasterly push is also expected which
would help increase precipitation production and anchor the
storms that develop near the Front Range and Palmer Divide.

For Sunday, precipitable water values will remain above normal
coupled with sufficient instability over the higher elevations. This
should be enough to support showers and thunderstorms but with
less coverage than the previous few days. Flow aloft will be weak
promoting slow storm motions, so heavy rain across the burn areas
from a passing storm remains a threat. The environment could
potentially be too stable to support thunderstorms which decreases
confidence in the flash flood threat Sunday.

Moisture will be in above average values for Monday indicating
another day with possibly higher coverage showers and thunderstorms.
Similar conditions continue into Tuesday. Slow storm motions and
high moisture keep the flash flooding threat a possibility both
days. Even with less rainfall, it may not take as much to impact the
burn areas given increased sensitivity from likely saturated
soils. Precipitable water values subtly decrease through the
remainder of the weak resulting in lower coverage thunderstorms in
the afternoon. This will reduce the flash flood threat Wednesday
through the end of the week.
