COOL AND CLOUDY TODAY WITH A SLIGHT CHANCE FOR ISOALTED LIGHT RAIN
SHOWERS
-
Cooler today as fall weather has settled over the region leading to
mostly cloudy skies this morning. High temperatures today will only
reach the upper 50's to low 60's on the plains with low to mid 50's
along the foothills.
-
A few lingering light showers this morning will continue off and on
through the day. A few light showers cannot be completely ruled out
along I-25 through this afternoon with skies gradually clearing
through this evening and overnight and into Friday. Overnight lows
will drop into the 40's along the plain with mid to upper 30's along
the foothills.
-
Today will officially conclude the 2021 Flash Flood Prediction
Program. Any questions or comments should be directed to Kevin Stewart
at 303-455-6277 or kstewart(a)mhfd.org. Thank you, from Skyview Weather!
With a chance for another day or two of unsettled weather, Skyview
Weather will provide complimentary service on Friday Oct 1st and
Saturday Oct 2nd, and will issue an HPO each day (and additional
products if warranted).
STORM RAINFALL POTENTIAL AND DURATION: Typical light rain showers will
produce a TR-0.1" in 10-30 minutes. A moderate rain showers could
produce 0.1-0.2" in 10-30 minutes.
WORST CASE SCENARIO: A stronger rain showers, or training of rain
showers has the potential to produce 0.2-0.6" in 60-90 minutes.
A LOOK AHEAD: An unsettled pattern will remain over the region both
Friday and Saturday resulting in a chance for rain showers/isolated
thunderstorms starting Friday afternoon. A chance for lingering
showers late Friday evening with off and on showers possible into
Saturday morning. Saturday will start to warm back into the 70's with
a slight chance for afternoon rain showers/isolated thunderstorms.

COOLER TODAY WITH A GOOD CHANCE FOR AFTERNOON/EVENING RAIN
SHOWERS/ISOLATED THUNDERSTORMS
-
Cooler today behind a cold front that moved through the region
yesterday. Today's high temperatures will only reach the mid 60's to
around 70 on the plains with low 60's along the foothills. A good
chance this afternoon for widespread rain showers with isolated
thunderstorms possible as well if temperatures are able to warm enough
this afternoon.
-
Best chance for rain showers activity today will be from 2-8pm with
lingering rain showers possible late into the evening with off and on
light rain showers possible through the overnight and into early
Thursday morning. Best chance for rainfall today will be along the
foothills where anchored rain showers will likely produce the most
rainfall.
-
Overnight temperatures will drop into the 40's along the plains with
mid to upper 30's along the foothills resulting in a chance for snow
this evening and overnight for areas above 9,000ft.
STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will
produce TR-0.2" in 10-30 minutes. A moderate rain showers or isolated
thunderstorm could produce 0.2-0.4" in 10-30 minutes.
WORST CASE SCENARIO: A strong thunderstorm, an anchored rain shower or
training or rain showers will have the potential to produce 0.8" of
rainfall in under 60 minutes.
A LOOK AHEAD: Another cold front will move through late this evening
effectively dropping tomorrow high temperatures into the upper 50's to
low 60's across the plains. A chance remains tomorrow afternoon and
evening for scattered rain showers. A slight warm up Friday as highs
reach the mid 60's to around 70 degrees with another good chance for
widespread rains showers/isolated thunderstorms. similar conditions
both Saturday and Sunday with chances for rain showers/isolated
thunderstorms in the afternoon and early evening.

-------------------------
Heavy Precipitation Outlook
Flash Flood Prediction Program
-------------------------
ISOLATED AFTERNOON TO EVENING SHOWERS/THUNDERSTORMS AHEAD OF COLD
FRONT TONIGHT
-
Today will be relatively warm with cloud cover increasing throughout
the day. Temperatures will reach the upper 70s to low 80s across The
District with dew points in upper 30s to around 40 degrees this
afternoon and early evening.
-
There is a small chance for isolated showers and thunderstorms this
afternoon to evening as moisture increases across the plains ahead of
tonight's cold front. Best chance for rain shower and isolated
thunderstorm activity will be between 1-9pm with off and on showers
possible through the overnight and into Wednesday morning. Storm
motions today will also be fairly brisk from the S/SW to N/NE between
10-20mph which will also help limit point rainfall amounts.
-
Showers and thunderstorms are expected to linger in the area through
this evening and will primarily affect the west slopes. Can't rule out
a stray shower or two along the foothills or Palmer Divide late
tonight and into tomorrow morning. Overnight lows will drop into the
upper 40's to low 50's for the plains with low to mid 40's along the
foothills.
STORM RAINFALL POTENTIAL AND DURATION: Typical rain showers will
produce a trace to 0.1" of precipitation in 10-30 minutes. A moderate
rain showers or isolated thunderstorm could produce 0.1-0.3" in 10-30
minutes.
WORST CASE SCENARIO: A stronger thunderstorm, or training of
thunderstorm cells has the potential to produce 0.3-0.8" in 60-90
minutes.
A LOOK AHEAD: An upper-level disturbance is positioned over Colorado
today and is on track to bring widespread showers across the foothills
and adjacent plains through the end of this week. This pattern is also
expected to bring a wave of fall temperatures to the high plains, and
snow to higher elevations along the western slope.

WARM, SUNNY, AND DRY AHEAD OF NEW WEATHER SYSTEM TOMORROW
-
Today will be warm, sunny, and dry with above average temperatures
across The District. Temperatures will reach the upper 80's to low
90's with afternoon dew points as low as 25 degrees.
-
The warming trend continues along the plains through today as an
upper level ridging begins moving east. Haze will be minimal as
westerly flow aloft transports a light smoke plume from West Coast
wild fires into The District.
-
Conditions will remain calm under mostly clear skies tonight with
overnight lows reaching the mid 50's.
STORM RAINFALL POTENTIAL AND DURATION: No precipitation is expected
today or this evening.
A LOOK AHEAD: The upper-level ridge which brought unseasonably warm
weather this weekend is beginning to move east as a new system
develops over the intermountain west. A disturbance moving north from
the Desert Southwest, coupled with the next wave moving southeast from
the Pacific Northwest, will bring unsettled weather to Colorado
beginning tomorrow. This system will pass over Colorado early on
Tuesday, increasing chances for isolated thunderstorms and widespread
showers across the foothills and adjacent plains through the end of
this week. The new pattern is also expected to bring the first wave of
fall temperatures to the high plains.
