Heavy Precipitation Outlook
Flash Flood Prediction Program
-------------------------
HOT WITH A CHANCE FOR HIGH-BASED AFTERNOON/EVE RAIN SHOWERS/ISOLATED
THUNDERSTORMS
-
High-pressure still dominates over the region today leading to
another hot day as high temperatures reach the low 90's this
afternoon. A weak disturbance will move through today bringing a
slight chance for a few high-based rain showers/isolated
thunderstorms. Some of these showers/thunderstorms already present
over NE portions of the state, and should stay east of the District
through the rest of the morning.
-
Additional storms will likely initiate between 1-3pm this afternoon
as the disturbance moves into the region. Typical storm movements will
be from NW to SE between 10-15mph helping limit point rainfall
amounts, however, a gust front could initiate additional, stationary
storms which could potentially increase chances for moderate to brief
heavy rainfall today. Storm chances will continue through 8pm before
skies start to clear through the rest of the evening.
-
Mild and dry conditions are expected through the overnight as lows
drop into the upper 50's to low 60's across the plains with low to mid
50's along the foothills.
STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers/isolated
thunderstorms will produce a trace to 0.1" in 10-30 minutes. A
moderate rain showers/isolated thunderstorm could produce 0.1-0.3" in
10-30 minutes.
WORST CASE SCENARIO: An anchored rain shower/thunderstorm, or training
of thunderstorm cells has the potential to produce 0.3-1.2" in 45-75
minutes.
A LOOK AHEAD: High-pressure holds through the rest of the week leading
to mostly hot and dry conditions into the weekend. A very slight
chance Thursday for another round of high-based shower activity,
mainly along the foothills and Palmer Divide at this time. Friday
remain hot and dry with highs in the 90's. Similar conditions both
Saturday and Sunday with highs in the 90's along with continued dry
conditions.

Heavy Precipitation Outlook
Flash Flood Prediction Program
-------------------------
WARM TODAY WITH MOSLTY DRY CONDITIONS LIKELY THROUGHOUT THE DAY
-
High-pressure will start to build over the region today leading to
mostly sunny skies, with mild and mostly dry conditions throughout the
day today.
-
High temperatures will be slightly above average in the upper 80's
to low 90's on the plains with low to mid 80's along the foothills.
Clouds will likely increase over the higher terrain this afternoon
with a very slight chance for a few scattered rain showers/isolated
thunderstorms along the Continental and Palmer Divide, however most
areas in and around the District will remain dry. Best chance for any
shower activity will be from 1-6pm with skies clearing into the
evening.
-
Mild conditions are expected to continue this evening with overnight
lows dropping into the upper 50's to low 60's on the plains with low
to mid 50's along the foothills.
STORM RAINFALL POTENTIAL AND DURATION: Typical high terrain rain
showers will produce a TR-0.1" in 10-30 minutes. a moderate rain
showers/isolated thunderstorm could produce 0.1-0.3" in 10-30 minutes.
WORST CASE SCENARIO: A stronger storm is able to develop along the
higher terrain and has the potential to produce 0.3-0.8" in 45-60
minutes.
A LOOK AHEAD: A slight uptick in mid to upper-level moisture, combined
with a weak disturbance tomorrow will bring a slightly better chance
for scattered rain showers/thunderstorms tomorrow, however, most will
likely be high-based which will bring minimal rainfall chances across
the District. Conditions dry out Thursday with highs continuing in the
90's. Another slight chance for scattered high-based storms Friday
afternoon and early evening, however the heavy rainfall threat will
remain minimal at this time.

WARM AND DRY WITH PLENTY OF SUNSHINE
-
A weak cold front has moved through this morning and will lower
temperatures a few degrees today with afternoon highs reaching the mid
to upper 80's over the plains with a few areas possibly touching 90
briefly. Foothills will remain in the 70's and lower 80's for highs.
-
There will be a few fair weather cumulus clouds that develop this
afternoon but no shower or thunderstorm activity will develop due to a
warm layer of air aloft capping cloud growth. Sunny skies this morning
will become mostly sunny to partly cloudy this afternoon.
-
Winds will be light, varying from N/NW to E/NE in the 5-15mph range.
STORM RAINFALL POTENTIAL AND DURATION: No precipitation expected today
or tonight.
A LOOK AHEAD: We will tack on a few degrees for highs on Tuesday with
readings in the upper 80's to lower 90's over the plains with more
comfortable 70's and 80's in the Front Range foothills. Dry conditions
are expected to persist over the lower elevations with possibly a very
isolated afternoon thunderstorm over the mountains and higher
foothills.

ISOLATED/HIGH-BASED AFTERNOON THUNDERSTORMS
-
Temperatures will continue to run above seasonal averages for the
date with afternoon highs topping out in the upper 80's to lower 90's
over the plains with 70's and 80's in the Front Range foothills.
Normal high for Denver today is 86 degrees. Surface moisture is
lacking but there is enough mid and high level moisture to result in a
build-up of clouds this afternoon and isolated thunderstorm activity.
-
Isolated thunderstorms will develop over the higher terrain between
1-2pm and then spread out onto the plains after 2pm with chances
through about sunset. After sunset dry conditions will develop and
continue through the remainder of the evening and overnight period.
-
Showers and weak thunderstorms will be high-based producing minimal
rainfall and gusty winds. Winds may gust up to 30-40mph or more
briefly in and near active storms. Typical storms will produce mainly
just some sprinkles but a few areas will likely pick up measurable
rain. There is no threat for heavy rainfall. Storms will move from W
to E at around 15mph.
STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak
thunderstorms will produce a trace to 0.2" of rain.
A LOOK AHEAD: Temperatures will continue to run in the upper 80's to
lower 90's for highs over the plains on Monday with dry conditions
over the District.

-------------------------
GENERALLY DRY WITH SLIGHTLY ABOVE NORMAL TEMPERATURES
-
Conditions will be generally dry District wide today with
temperatures running slightly above seasonal averages. Highs this
afternoon will top out in the upper 80's to lower 90's over the plains
with 70's and 80's in the Front Range foothills. Normal high for
Denver today is 86 degrees.
-
Sunny skies this morning will give way to partly cloudy skies this
afternoon as clouds build over the mountains and push eastward over
the I-25 corridor. No meaningful precipitation is expected but there
could be a few isolated sprinkles over the foothills and adjacent
plains but most areas will be completely dry today.
-
Surface winds will vary from SW to NW in the 5-15mph range with
occasional higher gusts.
STORM RAINFALL POTENTIAL AND DURATION: No meaningful precipitation
expected, mainly just a trace in areas that experience a light rain
shower or sprinkle.
A LOOK AHEAD: Temperatures will continue in the upper 80's to lower
90's for highs over the plains on Sunday. There will be a build up of
clouds during the afternoon and an isolated rain shower or weak
thunderstorm cannot be ruled out, favoring the foothills and Palmer
Divide. Ay storms that do manage to develop will produce minimal
moisture.

SEASONAL TEMPERATURES WITH WIDELY SCATTERED AFTERNOON THUNDERSTORMS
-
Trough of low pressure overhead will sag southward during the day
and result in widely scattered afternoon thunderstorms over the
District. Temperatures will warm into the mid and upper 80's over the
plains with 70's in the Front Range foothills. Normal high for Denver
today is 86 degrees.
-
Showers and weak to moderate thunderstorms will develop over the
foothills by early afternoon then spread out onto the plains between
1-3pm. Generally one round of showers/thunderstorms is expected over
the plains with conditions drying out between 6-8pm. Thunderstorms
will likely be more numerous W of I-25 and S of I-70. Storm motions
will be from W to E at around 15mph.
-
Thunderstorms are expected to be weak to moderate in intensity
producing mainly light to brief moderate rain. A stronger storm cannot
be completely ruled out and will have the potential for brief heavy
rainfall. After sunset conditions will dry out and remain dry for the
remainder of the evening and overnight period.
STORM RAINFALL POTENTIAL AND DURATION: Rain showers and weak
thunderstorms will produce a trace to 0.2" of rain. A moderate
thunderstorm will have the potential to produce rainfall rates of
0.2-0.5" in 10-30 minutes.
WORST CASE SCENARIO: A slow moving strong thunderstorm is able to
develop with the potential to produce rainfall amounts of 0.4-0.9" in
10-30 minutes.
A LOOK AHEAD: Drier air will move into the District on Saturday and
result in generally dry conditions over the plains with a few isolated
storms possible over the foothills and Palmer Divide. Temperatures
will tack on a degree or two with highs over the plains in the upper
80's to around 90 degrees.

Heavy Precipitation Outlook
Flash Flood Prediction Program
-------------------------
MOSTLY SUNNY WITH A CHANCE FOR AFTERNOON SHOWERS/THUNDERSTORMS
-
Warm conditions continue as an upper-level disturbance over the
Pacific Northwest transports a plume of moisture into the region,
supporting increased thunderstorm activity today with highs reaching
the upper 80âs to low 90âs this afternoon.
-
Initial storm development will occur along the higher terrain
towards the west between noon and 2pm. These storms will likely move
into the District between 1-3pm with the best chance for storm
activity through 9pm. Current dew points in the mid 40's to around 50
should mix out during the morning into the low to mid 40's effectively
limiting the amount of available, however, models suggest an uptick in
surface moisture this afternoon resulting in a LOW chance for Message
1 issuance this afternoon.
-
Storm motions will generally be from the NNW to ESE between 10-15mph
helping limit point rainfall amounts, however, additional storm
development along outflow boundaries has the potential to produce
slower moving, if not stationary storms at times. Storms today will
also likely be very pulse like with generally a trace to 0.2" of
rainfall, however a LOW threat today will see a storm produce a quick
0.5" in 10-15 minutes. Isolated higher amounts cannot be completely
ruled out at this time if stronger storms are able to develop,
although the threat will remain minimal today.
STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers/isolated
thunderstorms will produce a trace to 0.2" of rainfall in 10-30
minutes. A moderate to strong rain showers/isolated thunderstorm could
produce 0.2-0.5" in 10-30 minutes.
WORST CASE SCENARIO: A slow-moving or anchored rain shower/isolated
thunderstorm will have the potential to produce 0.5-1.5" in 45-75
minutes.
A LOOK AHEAD: With the weekend on the horizon, the District will once
again be in the cross hairs for an active weather pattern with storms
chances likely Friday, Saturday and Sunday. Tomorrow will likely be
the most active day with a good chance for afternoon and evening storm
activity with at least a moderate chance for heavy rainfall at this
time. Storm chances taper off slightly both Saturday and Sunday,
although a LOW threat will likely remain for moderate to heavy
afternoon rain showers/thunderstorms.

MOSTLY SUNNY WITH A MINIMAL CHANCE FOR ISOLATED SHOWERS AND
THUNDERSTORMS
-
Northwesterly upper-level flow aloft will continue today, creating
warm conditions with highs in the mid to upper 80's, dew points in the
low to mid 40's, by this afternoon. Water vapor satellite reveals a
dry airmass settled across the District today, limiting chances for
shower and thunderstorm activity.
-
Like yesterday, storm motions will be slow; between 5-10mph from the
NW to SE. PW values are expected to range from 0.6-0.7 inches with
shower and thunderstorm activity mostly limited to complex terrain.
However, a small chance remains for a few rain showers/isolated
thunderstorms across the District between 1PM-7PM.
-
Overnight, skies will gradually clear with mild conditions expected.
Lows will drop into the upper 50's to low 60's.
STORM RAINFALL POTENTIAL AND DURATION: Rain showers today will produce
a trace to 0.3 inches of rainfall in 10 to 30 minutes.
WORST CASE SCENARIO: A slow-moving or anchored rain
shower/thunderstorm will have the potential to produce 0.3-0.6 inches
in 10 to 30 minutes.
A LOOK AHEAD: On Thursday, an upper-level disturbance over the Pacific
Northwest will transport a plume of moisture into the region,
supporting increased thunderstorm activity. High temperatures will
reach the upper 80s to around 90 degrees. On Friday, scattered showers
and thunderstorms are likely during the afternoon and evening hours as
temperatures reach the upper 80s. Saturday will be similar with highs
in the upper 80s and a chance for isolated to widely scattered
thunderstorms.

MOSTLY SUNNY WITH A SLIGHT CHANCE FOR ISOLATED SHOWERS AND
THUNDERSTORMS
-
Northwesterly upper-level flow aloft will continue today, creating
warm conditions with highs in the mid to upper 80's, dew points in the
mid to upper 40's, by this afternoon. A dryer airmass is moving over
the District today, limiting chances for shower and thunderstorm
activity.
-
PW values are expected to range from 0.5 to 0.7 inches, with most
shower and thunderstorm activity expected across complex terrain.
However, a small chance remains for a few rain showers/isolated
thunderstorms across the District between 1PM-7PM. Like yesterday,
storm motions will be slow, between 5-10mph from the NW to SE.
-
Overnight, skies will gradually clear with mild conditions expected.
Lows will drop into the upper 50's to low 60's.
STORM RAINFALL POTENTIAL AND DURATION: Rain showers today will produce
a trace to 0.5 inches of rainfall in 10 to 30 minutes.
WORST CASE SCENARIO: A slow-moving or anchored rain
shower/thunderstorm will have the potential to produce 0.5-0.8 inches
in 10 to 30 minutes.
A LOOK AHEAD: High pressure ridging over the intermountain west will
create warm conditions across the Front Range Urban Corridor
throughout the week. Tomorrow will be similar to conditions today with
highs in the mid 80s to around 90 degrees and a slight chance for
isolated thunderstorm activity. By the end of the week, an upper-level
disturbance over the Pacific Northwest will transport a plume of
moisture into the region, supporting increased thunderstorm activity.
On Thursday and Friday, scattered showers and thunderstorms are likely
as temperatures reach the mid 80s.
