Area Forecast Discussion
National Weather Service Pueblo CO
616 PM MDT Sun May 3 2020

.SHORT TERM...(This evening through Monday)
Issued at 329 PM MDT Sun May 3 2020

Currently...Skies mostly sunny across the region. A dryline surge
was starting to push east from the mtns at K4VI and KTAD are gusting
from the SW while areas on the plains farther east and north still
have S to SE sfc winds. RH values were also starting to drop behind
the dryline. In the SLV, Red Flag conditions were occurring due to
the gusty winds and very low humidity values.

Just north of the CWA, TSRA were  noted forming over the Palmer
Divide. A few Q were also noted along the dryline.

Rest of Today into Tonight...

Main concern will be isolated TSRA potential over N El Paso and N
Kiowa counties late this afternoon and evening. Guidance has been
hinting on and off that we may see some isolated thunder these
regions during this time period. HRRR has also, on occasion, shown
an isolate storm over the far eastern plains, and given the bulge
pushing out. this cant be ruled out. Otherwise, the fcst area will
see mostly clear skies tonight. The only exception to this may be
the far eastern plains where some low clouds may build back west
later tonight.

Per SPC mesoanalysis page, mixed CAPE values pushing  500 J/Kg and 30-
40 knts of shear was noted, and even the Supercell Composite index
was showing some low numbers out east, so cant rule out an isolated
marginally svr storm during the next several hours.

As for the Red Flag, the San Luis Valley (SLV), southern mtns and
southern I-25 corridor will see critical fire weather conditions
into the evening hours due to the gusty SW winds and low RH values.

A rather strong cool front will push south across the Palmer Divide
around midnight, and across the rest of the plains during the early
morning hours of Monday. Gustiest winds will likely remain north of
and along US-50 during the nighttime hours.

Tomorrow...

Breezy conditions likely tomorrow in the morning most over the
plains, with winds slackening up over the I-25 corridor by later in
the afternoon, but will keep up over the far eastern plains.
Critical fire weather conditions are not expected tomorrow over the
plains as the combination of RH and winds should not exceed critical
values. However, it will be windy over the far eastern plains (but
RH values should be above 15%) while over the I-25 corridor RH
values will be critical, but winds should be relatively weak.

Over the mtns, a few areas, especially the northern SLV, will reach
critical values, but this is over a relatively small area, so no
fire weather highlights have been issued for tomorrow.

Cant rule out an isolated tsra over the Pikes Peak region tomorrow
and possibly down across the Wet Mtns, however nearly all areas will
remain dry with temps about 3-5F cooler than todays max temps.

.LONG TERM...(Monday night through Sunday)
Issued at 329 PM MDT Sun May 3 2020

Monday night-Tuesday night...Moderate westerly flow aloft continues
across the region with another embedded short wave translating across
the Rockies Monday night. The passing wave is progged to send another
cold front across the eastern plains Monday night, with the front
banked up across the lower slopes of the southeast mountains by
early Tuesday morning. With moisture pooling along and behind this
front, can't totally rule out a few possible showers across the
southeast plains Monday night and early Tuesday morning. With that
said, it seems the latest NAM nam solution is overdone with its
convection and have cut back on NBM pops and qpf across the plains
through Thursday morning. At any rate, Tuesday looks to start out
cloudy across the plains, with isolated to scattered showers and
a few possible storms, developing over and near the higher terrain
west of the I-25 Corridor Tuesday afternoon and early evening.
High temperatures across the plains on Tuesday will be cooler than
Monday, though will still be around seasonal levels, in the 60s
to lower 70s. Highs further west will be near Monday's readings,
in the mid 60s to lower 70s across the high mountain valleys, with
mainly 50s and 60s across the higher terrain. While there will
continue to be a few areas of critical fire weather conditions
across the high mountain valleys through this period, current
forecast does not indicate widespread enough conditions to issue
any fire weather highlights at this time.

Wednesday-Thursday...Short wave upper level ridging is progged across
the area Wednesday, with more energy progged to dig down the back side
of the ridge across the Plains on Thursday. This keeps warm and mainly
dry conditions across the area through this period, with a stronger
cold front progged to dive across the eastern Plains Thursday afternoon
and evening, bringing chances of precipitation across the plains
Thursday night. Temperatures warm back to above seasonal levels
areawide, with the potential for more widespread critical fire weather
conditions on Thursday.

Friday-Sunday...Moderate northwest flow aloft continues to be progged
across the region, as a broad upper trough carves out across the
central Conus and upper level ridging redevelops across the Desert
Southwest through the Intermountain West. Latest models continue to
differ on timing and location of minor embedded waves translating
across the region through the weekend, and again stayed with current
NBM pops, which brings chances for showers over and near the higher
terrain each afternoon. Temperatures through the period look to cool to
near seasonal levels, most notably across the plains.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 606 PM MDT Sun May 3 2020

VFR and dry conditions across the TAF sites this period. Latest
radar imagery is depicting some isolated shower and thunderstorm
development just to the north of COS at this time, however, this
development is expected to stay to the north. There could be a
stray shower that moves around COS early this evening, but impacts
are not expected and have left out any mention of precip. Winds
will generally be from the southwest to west this period across
ALS, but for COS and PUB expect some varying wind direction
beginning as soon as this early. Surface trough/front expected to
swing through and allow current south southeast winds to quickly
shift to a northerly direction while remaining gusty. There is
some potential for winds/gusts to diminish later tonight into
early Monday morning, but it is appearing more probable for
another increase in speeds and have trended the forecast this way.

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

.DAY ONE...This Afternoon and Tonight

High fire danger is expected this afternoon and evening in the San
Luis Valley, over the southern I-25 corridor and in the Sangre de
Cristo and Wet mountains. These areas will have gusty winds, low
humidity, and dry vegetation, which will create conditions
favorable for rapid rates of fire growth and spread.

Isolated thunderstorms will be possible late this afternoon and this
evening in Teller and El Paso Counties, and in Kiowa County this
evening.  The main storm risks will be wind gusts up to 45 mph, and
cloud to ground lightning.  However, it is possible that one or two
storms in El Paso County could produce hail up to the size of
pennies.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Elevated fire weather conditions are possible Monday afternoon
over portions of the San Luis Valley and Fremont County due to
breezy conditions and low humidity values.

A few thunderstorms are possible on the Eastern Plains on Tuesday
afternoon.

High fire danger is once again expected Wednesday over the San
Luis Valley. These conditions will spread eastward into the
Interstate 25 corridor on Thursday.

Periods of showers and thunderstorms will be possible across the
region Friday into Sunday.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this evening in El Paso County.
