Area Forecast Discussion
National Weather Service Pueblo CO
307 PM MDT Thu Jul 25 2019

.SHORT TERM...(This evening through Friday)
Issued at 306 PM MDT Thu Jul 25 2019

Currently...A ridge of high pressure remains over the Four Corners
region, recycling trapped moisture for convection over the higher
terrain and adjacent plains. Numerous showers and short-lived
thunderstorms have developed as of 3 pm, but so far none have
posed a threat for area burn scars. Temps have warmed into the 70s
and 80s for the high valleys, and mid 80s to mid 90s for the
plains.

Tonight...Ongoing convective activity will continue and spread
across the adjacent plains through the evening, with hi-res models
indicating activity lingering until around midnight. Since the winds
aloft are very weak, area burn scars are still under the threat of
flash flooding if any stronger storms develop and slowly move across
them. Therefore, the Flash Flood Watch will remain in effect until
midnight tonight. Further east, the main threat from storms will be
gusty erratic winds with gusts up to 50 mph and cloud to ground
lightning. One or two of the storms may become strong enough to
produce hail up to one half inch in diameter, but reports have
indicated a lot of rain with these storms this afternoon and no
hail. Expect overnight low temps in the upper 40s to lower 50s for
the high valleys, and mid 50s to mid 60s for the plains.

Tomorrow...It looks like a very similar day for Friday, though the
center of the upper high shifts slightly to the southwest, settling
over southern AZ. This will mean a shift in the focus areas for the
heavier rain areas. Models are indicating a similar initiation time
for convection over the higher terrain, between 10 and 11 am, but
are showing very little movement off of the mts. Therefore, the I-25
corridor may see a few storms try to threaten in the afternoon and
early evening, but those storms may not get too far east. In
addition, the focus area for the heavier rain looks like it will be
over the southern Sangres and the Raton Mesa, which would still keep
the Spring burn scar under the threat of flash flooding. Plan on
high temps around 80F for the high valleys, and mid 80s to mid 90s
for the plains. Moore

.LONG TERM...(Friday night through Thursday)
Issued at 306 PM MDT Thu Jul 25 2019

Saturday and Sunday...

An upper-level trough of low pressure begins to move in from the
Pacific Northwest on Saturday, riding along the northern extent of
the Desert Southwest ridge. This trough is expected to bring
increased chances of precipitation to the area, especially for the
mountains. However, latest model runs continue to differ on the
amount and extent of precipitation. The NAM continues to be the
wettest of the models, showing that the precipitation will extend to
the plains Saturday night. The GFS also shows this, but with less
areal extent, while the Euro is indicating that the precipitation
will remain over the mountains. With precipitable water values being
on the higher end, there will be an enhanced burn scar flash flood
threat Saturday afternoon and evening.

The trough is expected to continue progressing eastward Saturday
night into Sunday, dropping a cold front southward through the area.
The cold front should bring another chance for afternoon showers and
thunderstorms to the mountains and possibly the southeastern plains,
depending on where the front is located during the evening hours.
The GFS locates the front farther southeast in the OK and TX
panhandles, while the Euro has it clipping the southeast corner of
CO. Highs are expected to be near average in the 90s across the
plains, and upper 70s to 80s in the mountain valleys, with Sunday
being the slightly cooler day of the two.

Monday through the work week...

The Desert Southwest ridge slides back to the east on Monday, and
generally remains over the Four Corners region. Enough monsoonal
moisture is expected to be transported into the region to bring
daily afternoon shower and thunderstorm chances over the mountains.
Thunderstorm coverage should be isolated to scattered early in the
week, then becoming more widespread later in the week. Highs during
the week are expected to be in the mid to upper 90s, with a few
locations possibly hitting 100 midweek, across the plains, and low
to mid 80s in the mountain valleys.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 306 PM MDT Thu Jul 25 2019

Thunderstorms will gradually move across the adjacent plains
through the evening, and will likely linger until around midnight.
A repeat pattern is forecast for Friday, though activity will
likely be more tied to the higher terrain with a focus on the
southern Sangres and Raton Mesa.

KALS: VCTS until around 01z with potentially gusty erratic winds
to 50 kts. Otherwise VFR conditions overnight until 18z Fri.

KCOS and KPUB: VCTS until 07z with gusty erratic wind gusts to 50
kts and intermittent MVFR visibilities due to brief heavy rain.
Otherwise VFR conditions will prevail until 21z Friday.

1109 AM MDT Thu Jul 25 2019

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This Afternoon and Tonight

Widespread thunderstorms will develop over the mountains this
afternoon, increasing the risk for flash flooding over the
Spring, Junkins, and Hayden Pass burn scars. There may be one or
two strong thunderstorms over the plains this afternoon, with the
main risks being wind gusts up to 40 mph, nickel sized hail, and
cloud to ground lightning with the strongest storms.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Scattered to numerous showers and thunderstorms will be possible
across the mountains Friday through Sunday with the best chance for
thunderstorms across the plains on Saturday night and Sunday.
Locally heavy rainfall and lightning will be the primary storm
threats. However, brief small hail and wind gusts up to 45 mph
will also be possible with the stronger storms. The risk for flash
flooding on burn scars will remain elevated through this period.

Drier and hotter weather will spread in for Monday and Tuesday with
isolated to scattered thunderstorms across the mountains each day.
Gusty erratic outflow winds, brief moderate to heavy rainfall, and
lightning will be the primary storm threats.

Thunderstorm chances will increase again for mid to late week.
This will bring back the risk for locally heavy rainfall and the
potential for flash flooding of burn scars, as monsoon moisture
returns to the region.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible across the mountains and the eastern plains this afternoon
and evening.
