Area Forecast Discussion
National Weather Service Pueblo CO
1013 AM MST Sun Nov 12 2017

.SHORT TERM...(Today and tonight)
Issued at 402 AM MST Sun Nov 12 2017


Some patchy low clouds and fog were noted here and there across the
cwa this morning. Most persistent fog was noted over the far eastern
plains vcnty Lamar although some lighter fog was note over the Pueblo
region. Otherwise skies were clear over the region. Temps over the
plains were generally in the 30s with 20s in the valleys and teens
in the mtns.


A cooler air mass is over the plains today while an above seasonable
airmass is over the mtns and valleys. Temps on the plains today will
be about 5F below normal while in the valleys it will be about 10F
above normal. Expect highs in the 50s across the plains and valleys

Pockets of morning fog and low clouds will give way to mostly sunny
skies later this morning, but increasing high clouds will move
across the region later today.


quite a bit of generally thin high cloudiness will be over the
region tonight, although some patch fog will be possible once again
mainly over the  far eastern sections. Lows will fall into the 30-
35F range on the plains with 20s valleys. Breezy conditions will be
possible later tonight over the far se plains, while the mtn tops
winds will also be on the increase. The remainder of the region will
see light winds.

.LONG TERM...(Monday through Saturday)
Issued at 402 AM MST Sun Nov 12 2017

Monday and Tuesday...Westerly zonal flow is forecast across the
state for both Monday and Tuesday, providing for dry and warm
conditions for the forecast area. Expect highs in the 60s for the
high valleys, and 70s across the plains. an upper shortwave will
cross the northern Rockies Tue, pushing a cold front south into
Colorado during the evening.

Wednesday...A much cooler day on tap for the state in the wake of
the cold front Tue night. Northerly sfc winds overnight will become
easterly upslope through the morning, but will swing around to the
south in the afternoon as the next system approaches. Expect highs
in the 50s to around 60F, which will be a 15 to as much as a 20
degree drop in temps from the previous day.

Thursday through Saturday...A stronger upper level system crosses
the Pacific NW Thursday, shifting the flow aloft across the Four
Corners region to a more southwest direction. This will draw some
moisture up into western Colorado Thursday morning, then as the
system crosses the Great Basin and northern Rockies Thu night
through Friday, another cold front is forced south into Colorado.
Therefore...look for snow showers along the Continental Divide
Thursday morning through Friday morning, then tapering off Fri
afternoon across the central mts as the system passes and continues
to the east. The upper ridge builds back in on Saturday, with cool
northwest flow continuing across the forecast area. Another concern
will be the strong gusty winds expected across the area Thu aftn
through Fri, and these developing conditions will have to be
monitored. As for temps, look for highs in the 50s to around 60F for
the high valleys and 60s for the plains on Thu, then for Fri and Sat
50s to near 60F for all areas. Moore
