Area Forecast Discussion
National Weather Service Pueblo CO
408 AM MST Wed Nov 22 2017

.SHORT TERM...(Today and tonight)
Issued at 344 AM MST Wed Nov 22 2017

Quiet weather over the area today as western U.S upper ridge
translates eastward over the next 24 hours.  Aside from some high
level wave cloudiness at times the forecast for southern CO will
remain dry. Clouds should be thickest and most widespread this
morning...before thinning and clearing towards afternoon as drier
air spreads in. High temperatures today should rebound
nicely...though have some concerns that performance won`t be as
great as guidance is giving across the far eastern plains due to
lighter winds.  Have generally split the difference for now.

Another round of wave cloudiness and lee troffing should keep min
temps tonight on the warm side. -KT

.LONG TERM...(Thursday through Tuesday)
Issued at 344 AM MST Wed Nov 22 2017

...Prolonged period of dry/warm weather to continue...

Swrn U.S. upper ridge builds slightly N and E Thu, then is briefly
flattened by short wave energy racing eastward across the nrn
Rockies Thu night into Fri. Ridge then rebuilds over the weekend,
before fairly strong upper trough pushes across the wrn U.S and
into the central Rockies Mon/Tue. Combination of weak lee trough,
modest wly flow and warm mid level temps will lead to a very
warm Thanksgiving day across the region, and maxes will approach
record highs at Pueblo(record 73f in 1925, forecast 73f) and
Colorado Springs(record 69f in 1925, forecast 69f) by late day.
Thu night and early Fri look breezy to windy at times, before
surface cold front drops south through the plains Fri afternoon as
upper wave ejects into the nrn Hi Plains. Temps will likely remain
mild through Fri afternoon, and a few 70s look likely on the
plains ahead of the front. Sat maxes will run around 10f lower
than Fri across the eastern half of the area as cooler air
filters south, while mountains and valleys see little temp change.
Temps then rebound Sun/Mon ahead of strong trough digging into the
wrn U.S. though winds will likely become strong Mon as surface
pressure falls over the central Plains. As trough ejects late Mon
into Tue, a chance of snow will return to at least the Continental
Divide, with a few showers elsewhere over the high terrain as
system pushes into the central plains by mid-week
