Area forecast discussion, Jun 7, 3:37 PM MDT, 1 hour 56 minutes before

Area Forecast Discussion
National Weather Service Pueblo CO
337 PM MDT Thu Jun 7 2018

.SHORT TERM...(This evening through Friday)
Issued at 338 PM MDT Thu Jun 7 2018

.Currently...moisture has been slower to mix out on the plains
today.  Convection tried to fire over the southeast mountains, but
moisture was too shallow and air aloft was too dry to support deeper
convection.  Some weak storms are over Teller County and along the
Raton Ridge.

.Tonight...Fine resolution models continue to show some weak storms
moving eastward along the Palmer Divide and along the New Mexico
border during the evening.  ESRL experimental HRRR hints at strong
storms over Kiowa County later in the evening.  This is plausible as
moisture has been slow to mix out on the plains and southeast winds
will continue into the evening.  Deeper cloud have limited heating
over Baca County which should limit instability in the southeast
corner of the state. Any storms should move into Kansas by midnight.
Do not see a large MCS developing, like what developed last night,
to provide a strong westward push to the low level moisture.

.Friday...Dry southwest flow aloft continues.  Low levels on the
plains will be drier than Thursday.  Winds will stay below red flag
criteria, but humidities will mostly be below 15 percent.  There may
be enough low level moisture for some isolated stronger storms near
the Kansas border, and SPC has marginal risk for the Kansas border
region. Suspect main threats will be gusty winds with drier lower
levels.  A stray storm could develop over the eastern mountains, but
moisture will be limited. --PGW---

.LONG TERM...(Friday night through Thursday)
Issued at 338 PM MDT Thu Jun 7 2018

Chief longer term meteorological issues continue to be
temperatures, near critical to critical fire weather
conditions at times and pops.

Latest longer term PV/Precipitable water analysis, forecast
model soundings and computer simulations suggest that upper
ridging will remain anchored centered over/near New Mexico/west
Texas during the balance of the longer term with increasing
precipitation potential beginning Tuesday and continuing into
next week as deeper atmospheric moisture returns/develops over
the majority of the CWA.

From Friday evening into Monday, unseasonably warm temperatures in
combination with generally dry conditions(outside of isolated
thunderstorms) are are anticipated over the forecast district in
advance of the potential for cooler temperatures as well as
increased pops beginning Tuesday.

Gradient winds are still projected to increase from Sunday into
Monday evening, which will increase the fire weather threat
Sunday. In addition, elevated/localized fire weather conditions
will also be possible Saturday and Monday.

Finally, above to well-above seasonal early to mid-June
temperatures(as evidenced by predicted maximum temperatures
climbing into the 90s and even challenging the century mark at
times over select eastern locations) are expected to continue over
southern Colorado into Monday, in advance of somewhat cooler
temperatures developing by Tuesday and Wednesday.

&&

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 338 PM MDT Thu Jun 7 2018

VFR at all TAF sites.  Isolated storms north of KCOS could brief
produce gusty outflow winds at KCOS.  Chances for thunder and wind
gusts are too low to insert into TAF.

.PUB WATCHES/WARNINGS/ADVISORIES...

NONE.
