Hail in Colorado, July 4, 2019

Area Forecast Discussion
National Weather Service Pueblo CO
318 PM MDT Thu Jul 4 2019

.SHORT TERM...(This evening through Friday)
Issued at 317 PM MDT Thu Jul 4 2019

Currently...

Quite a bit of low level moisture was noted over most of the plains
at 2 pm as dewpts generally east of a line from Monument to Kim were
in the 50s and L60 while west of this line they were in the 20s.
Associated CAPE over the area was 1000 to 2500 J/KG where the low
level moisture was present while it was near zero in the drier
air. Shear was modest with values of 20 to 30 knts mainly N of US
50.

Radar as sat pix was showing convection trying to form over El Paso
county and over the far southeast plains.

Rest of today and tonight...

Main concern will be the chance of a severe storm or two over parts
of the region. The overall best chance will be over mainly N El Paso
county this afternoon, with more isolated storms possible over the
far southeast plains. Any storm that can sustain itself will be
capable of producing large hail and damaging wind gusts.
Convection, if it gets initiated, should end over El Paso county
by early evening. COnvection over the far southeast plains will
last well into the evening.

Over the rest of the region mainly clear skies are anticipated. Lows
tonight should fall in the U50s to 60s across the plains with 40s
and 30s over the higher terrain.

Tomorrow...

Thunderstorms will be possible over the mountains and far eastern
plains by mid to late afternoon. SPC has most of the plains in a
marginal risk as the moisture should spread all the way into the
mtns/plains interface. Likewise, bur scar flooding may be an issue
tomorrow. A few of the storms tomorrow on the plains will likely
produce some marginal severe hail and wind gusts.

temps tomorrow will be a bit cooler than today with readings mainly
in the upper 80s to lower 90s.

.LONG TERM...(Friday night through Thursday)
Issued at 317 PM MDT Thu Jul 4 2019

Friday night through Sunday...The axis of a relatively flat upper
ridge will be located over OK and TX over the weekend. The passage
of a cold front early Fri will set up a dynamic situation for the
eastern mts and plains through Sun evening as increased llvl
moisture will provide ample fuel for thunderstorms. Easterly surface
winds Fri evening, and southeast winds through Sat, will force this
moisture up against the eastern slopes of the southern Front Range,
and the focus area for numerous slow-moving thunderstorms will be
along the eastern mts and I-25 corridor. The eastern plains will see
plenty of convection as well, but again the eastern slopes will be
the focal areas and burn scars will need to be monitored closely.
The activity will carry over into Sun, but the forecast surface
winds will be out of the south so llvl moisture will be slightly
lower through the day, and storms that do develop will be less
likely to remain training over a specific location. Expect lows
around 50F for the high valleys, and mid 50s to lower 60s for the
plains. High temps on Sat should be a bit cooler due to increased
cloud cover and pcpn chances, with highs in the 70s for the high
valleys, and mid 70s to lower 80s for the plains. Sun will begin to
warm back up, with max temps in the 70s to near 80F for the high
valleys, and 80s to near 90F for the plains.

Monday and Tuesday...Warming temps and diurnal mt convection for all
of the higher terrain is expected for the start of the work week, as
the flat upper ridge remains in place. There is a disturbance
passing well to the north of the state on Mon, but it should not
affect sensible weather across the forecast area. Expect scattered
convection over the mts and isolated activity elsewhere on Mon, then
much more isolated activity for all areas on Tue. Look for highs in
the 70s for the high valleys and mid 80s to around 90F for the
plains on Mon, then on Tue temps will warm to around 80F for the
high valleys, and upper 80s to mid 90s for the plains.

Wednesday and Thursday...The upper ridge slides back to the west
across CO and NM, and moisture trapped under the high will be
recirculated for isolated to scattered diurnal mt convection each
aftn and eve. Max temps will climb into the 80s for the high
valleys, and upper 80s to mid 90s for the plains. Moore

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 317 PM MDT Thu Jul 4 2019

Some convection will be possible in the vicinity of KCOS this
afternoon and early evening, and tomorrow afternoon and early
evening. I cannot rule out some low cigs tonight at KCOS if enough
low level moisture makes it back to the mtns.

KPUB and KALS should be VFR the rest of today and into tomorrow
afternoon. A thunderstorms will be possible over KPUB late tomorrow
afternoon and evening.

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

.DAY ONE...This Afternoon and Tonight

A few thunderstorms will be possible this afternoon and early
evening generally east of a line from Monument to Truckton to La
Junta to Kim. One or two of these storms could become severe, with
hail the size of quarters and wind gusts around 60 mph. The best
chance for severe storms will be northern El Paso county and the
far eastern plains of southeast Colorado.

All thunderstorms will contain deadly cloud to ground lightning.
Several people have already been injured by lightning in Colorado
this year. Please seek safe shelter if storms are nearby. When
Thunder Roars...Go Indoors!

High river flows from snow melt runoff will continue today, with
portions of the Arkansas River and the Rio Grande running high. Some
minor flooding is possible in the lower Arkansas River Valley near
Avondale.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Scattered thunderstorms will develop over the mountains and will
propagate over the lower elevations during Friday afternoon. Some
of the storms may become severe, with the main risks being half
dollar sized hail, 60 mph winds, and cloud to ground lighting.
Flash flooding is possible over the Spring, Junkins, and Hayden
Pass burn scars from locally heavy rainfall.

There will be daily thunderstorm chances Saturday through
Wednesday. Mountain thunderstorms are anticipated to form during
the early afternoon hours, then will develop over the mountain
valleys and over the plains. Gusty thunderstorm outflow winds,
nickel sized hail, and cloud to ground lightning are possible.
Daily thunderstorms over the mountains mean that there is a daily
chance of flash flooding over the burn scars from locally heavy
rainfall.

Rivers and streams will continue to flow high due to snow melt run
off through the next several days.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this afternoon and early this evening over northern El
Paso county and the far eastern plains of southeast Colorado
