422 am MDT Tuesday Sep 27 2016

Short term...(today and tonight)
issued at 422 am MDT Tue Sep 27 2016

Upper ridge and light northerly flow aloft will keep dry weather
over the region again today. 700 mb temperatures rebound a few degrees
over yesterday which should net highs into the 80s across the plains
with a mix of 60s and 70s for the Mountain/Valley communities. Old
upper low begins to migrate northward into Southern California and southwest
Arizona tonight. Main influence will be for some high clouds to invade
southwest portions of the area. Otherwise...expect another cool
night with lows in the 40s...except 30s across the mountains and
valleys. -Kt

Long term...(wednesday through monday)
issued at 422 am MDT Tue Sep 27 2016

Wednesday...an upper low over Southern California will open up and migrate
across the Great Basin starting Wed, drawing moisture up across the
4 corners into western Colorado. The ridge of high pressure over the state
will slide to the east through the day, with the ridge axis reaching
the eastern border Wed night. Models indicate that some isolated
showers will move into the Continental Divide late Wed aftn, with lingering
isolated activity overnight. Look for Max temps in the 70s for the
high valleys, and in the 80s for the eastern plains.

Thursday through Saturday...an upper low off the coast of the
Pacific northwest will start to gather strength beginning Thu, with
increasing SW flow aloft streaming across the $ corners and Great
Basin into Colorado. Pcpn chances will persist all three days, first
across the higher terrain on Thu, then for all of the warning area
Fri and Sat. Temps should cool a degree or two due to increasing
cloud cover, with Max temps in the mid 60s to lower 70s for the high
valleys, and mid 70s to around 80 f for the plains.

Sunday and Monday...the next upper low pressure makes landfall over
the Pacific northwest on sun, with a tightening pressure gradient helping to
increase west-SW winds aloft across the western US. Expect isolated to
low-end scattered convection across the higher terrain and Palmer
dvd both days, and temps holding right at around seasonal norms.
