HOT SUMMERTIME CONDITIONS WITH ISOLATED AFTERNOON THUNDERSTORMS
Today will be mostly sunny with afternoon temperatures in the mid
80s, dew points in the low 50s, and a chance for isolated showers and
thunderstorms. Like yesterday, the best time for storms today will be
during the late afternoon hours with storms moving from the northwest
to southeast between 25 and 35 MPH, which will help limit point
rainfall amounts. However, a gust front from a stronger storm could
potentially cause slow storm movement, leading to isolated brief heavy
rainfall. Thunderstorm activity is expected to subside across the
Front Range Urban Corridor by mid-evening. Skies will clear overnight
with lows falling into the low 60s.
STORM RAINFALL POTENTIAL AND DURATION: Typical thunderstorms will
produce moderate rainfall of up to 0.25” in 10-30 minutes. Strong
thunderstorms have the potential to produce heavy rainfall up to
0.75” in 10-30 minutes.
WORST CASE SCENARIO: Anchored thunderstorms have the potential to
produce 0.75” to 1.50” in 60 minutes.
A LOOK AHEAD: Warmer and drier weather will build into the region
beginning Sunday as a strong heat wave expands across the
intermountain west. Afternoon temperatures will climb into the upper
80s to low 90s under clear and sunny skies. Heat will intensify Monday
with temperatures about 10 degrees above normal. Very dry conditions
will be more widespread as afternoon temperatures are expected to
reach or exceed 100°F on the plains.

MESSAGE 1'S HAVE BEEN RESCNIDED/MESSAGE 4'S (ALL CLEAR) ISSUED
Message 1’s have been rescinded and Message 4's (All Clear) has
been issued as the threat for heavy rainfall has ended for the day.
The late evening round of thunderstorm activity that impacted isolated
areas of the District has pushed to the east and weakened. The
boundary that spawned the storms has also washed out and in tandem
with cooling temperatures a more stable air mass is now in place.
Dry conditions are expected for the remainder of the evening and
overnight period.
STORM RAINFALL POTENTIAL AND DURATION: No precipitation is expected
for the remainder of the overnight period.

-------------------------
MESSAGE 1'S ISSUED FOR THE ENTIRE DISTRICT
Message 1’s have been issued for the entire District and will be
valid until 1:00 AM Saturday.
A boundary has moved in from the N/NE and has sparked late evening
thunderstorms which may become more numerous over the next few hours.
Relatively fast storm motions will help to reduce point rainfall
amounts from a single storm with training of thunderstorm cells
possibly producing periods of heavy rainfall that may result in
excessive runoff.
Thunderstorms will generally move from WNW to ESE at 20-25mph with
stronger storms potentially moving more slowly. Strong thunderstorms
may also contain hail, gusty winds as well as brief heavy rainfall.
Best chances for storms will be over the next 2-3 hours, most likely
favoring areas along and E of I-25.
STORM RAINFALL POTENTIAL AND DURATION: Moderate to strong
thunderstorms will have the potential to produce rainfall rates of
0.5-1.2” in 10-30 minutes.
WORST CASE SCENARIO: Training of thunderstorm cells may produce heavy
rainfall of up to 2.0” in 60-75 minutes.

HOT, BREEZY AND DRY
Strong westerly flow aloft will bring breezy and dry conditions
across the District today and this evening. Winds will pick up from
the west this afternoon with gusts up to 25mph.
Full summer sun will bring the hottest day of the year with highs in
the mid 90’s this afternoon. Overnight lows will drop into the low
to mid 60’s on the plains with upper 50’s to around 60 degrees
along the foothills.
STORM RAINFALL POTENTIAL AND DURATION: No precipitation is expected
today or this evening.
A LOOK AHEAD: Similar high temperatures tomorrow as highs reach the
low to mid 90’s with mild and dry conditions. Not much change to
start the day Thursday, with high temperatures once again reaching the
90’s. A slight chance Thursday afternoon for a round of high-based
showers/isolated thunderstorms with minimal impacts for the District.

EVEN WARMER TODAY WITH A FEW HIGH-BASED AFTERNOON SHOWERS/ISOLATED
THUNDERSTORMS
High-pressure starts to build over the region today leading to more
seasonable high temperatures this afternoon with highs reaching the
low 90’s in some spots.
A chance for showers/isolated thunderstorms this afternoon, with prime
time between 1-7pm. Storm motions should be relatively quick, between
10-20mph which will help limit point rainfall amounts if good
showers/thunderstorms are able to develop. Generally, storms will be
high-based today, bringing minimal rainfall. However, if surface dew
points stay elevated through the afternoon there will be a slightly
better chance for storm development, especially areas east of I-25.
Skies will clear this evening with mild conditions through the
overnight. Overnight lows will drop into the low 60’s on the plains
with mid to upper 50’s along the foothills.
STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will
produce a TR-0.10” total, in 10-30 minutes. A weak thunderstorm
could produce 0.10-0.30” total in 10-30 minutes.
WORST CASE SCENARIO: A moderate to strong thunderstorm is able to
develop, will have the potential to produce up to 0.6” in under 60
minutes.
A LOOK AHEAD: High-pressure really takes hold tomorrow, bringing mild
and dry conditions throughout the day. High temperatures will reach
the low to mid 90’s in the afternoon tomorrow. Similar conditions
Wednesday with highs in the low 90’s with continued mild and dry
conditions. Not much change to start the day Thursday, with high
temperatures once again reaching the 90’s. A slight chance Thursday
afternoon for another round of high-based showers/isolated
thunderstorms with minimal impacts for the District.

WARMER, MILD AND GENERALLY DRY
Westerly upper-level flow aloft will turn northwesterly throughout
the day today. This will likely result in dry conditions across the
District today, this afternoon and through this evening.
A slight chance for a few high-based showers/isolated thunderstorms
along the higher terrain and Palmer Divide. A very slight chance any
of these showers will move into the District this afternoon and
evening. If any shower activity does move into the District, minimal
rainfall will reach the surface as most rain showers mix out as they
move off the higher terrain.
High temperatures today will reach the 80’s under mostly sunny
skies. Overnight lows will drop into the upper 50’s to around 60 on
the plains with low to mid 50’s along the foothills.
STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will
produce a TR-0.10” total, in 10-30 minutes. A weak thunderstorm
could produce 0.10-0.30” total in 10-30 minutes.
WORST CASE SCENARIO: A stronger thunderstorm is able to develop will
have the potential to produce up to 0.6” total, in under 60 minutes.
A LOOK AHEAD: High-pressure continues to build through the week
resulting in mostly dry conditions for the District. A slight chance
will continue through the week for high-based showers/isolated
thunderstorms, however, shower activity should remain along the higher
elevations, with minimal, if any, precipitation for the District
through the week.

MESSAGE 1’S WILL BE ALLOWED TO EXPIRE AT 10:00 PM
Message 1’s will be allowed to expire at 10:00PM as the threat of
heavy rain has come to an end.
A few showers and a weak thunderstorm or two will be possible over the
next few hours as the tail end of today’s disturbance continues
eastward. If any storms develop, they are expected to favor eastern
portions of the District through 2:00AM. Quick storm motions from
northwest to southeast, between 25-35 mph will limit any point
rainfall amounts.
Overnight lows will remain in the mid to upper 50’s across most of
the District. Warmer daytime temperatures are expected tomorrow as
high pressure ridging expands across the Desert Southwest with only a
slight chance for showers and thunderstorms Sunday.
STORM RAINFALL POTENTIAL AND DURATION: Typical showers will produce a
trace to 0.20” total, in 10-30 minutes. A weak thunderstorm could
produce 0.20-0.40” total, in 10-30 minutes.
WORST CASE SCENARIO: A moderate to strong thunderstorm has the
potential to produce up to 0.80” total, in 45-60 minutes.
