.SHORT TERM...(This evening through Tuesday)
Issued at 241 PM MDT Mon Mar 19 2018

As expected, some instability showers have been occurring over and
close to the higher terrain, and this will continue into the early
evening hours, but then should end.  However, some light snow
showers could continue over the higher elevations of Lake county
thru the night, but shouldn`t really amount to anything.  Also,
gusty winds over the southeast plains will decrease this evening.

On Tue dry weather is expected along with lighter winds acrs the
southeast plains.  Temps are forecast to be a couple to a few
degrees warmer than today.

.LONG TERM...(Tuesday night through Monday)
Issued at 241 PM MDT Mon Mar 19 2018

Upper ridge migrates across the Rockies Wed/Thu, with generally
warm and dry weather over srn Colorado. While surface RH will drop
to near or below 15 percent over the eastern mountains and plains
both days, winds should stay generally below 25 mph, though a few
spots near the KS border could get close by Thu afternoon as lee
trough deepens. Max temps by Thu afternoon will climb back to well
above average levels, as 70s reappear along the I-25 corridor and
across the eastern plains. Upper trough then moves onshore along
the Pacific Coast Thu night with lead short wave pushing inland
through the Great Basin on Fri. Precip should develop by sunrise
Fri along the Continental Divide as upward motion increases, with
a mix of rain and snow showers spreading eastward across interior
valleys and and remainder of the mountains during the day. Could
see some brief bursts of heavier snow Fri afternoon along the
divide as wave moves across and convective instability peaks, then
precip fades away quickly Fri night as wave moves rapidly into
the ern plains. Eastern mountain slopes and far sern plains will
miss most precip Fri, as wly downslope winds increase, and with RH
falling below 15 percent, critical fire weather conditions look
likely for a large swath of the region from I-25 eastward. Max
temps will continue well above average Fri, with low to mid 80s on
the plains.

Next upper wave then moves quickly through the Central Rockies
over the weekend, keeping breezy to windy conditions in place
across srn CO both Sat and Sun. Most precip with this system will
remain across nrn CO, though a brief period of snow showers looks
possible along the Continental Divide late Sat as srn edge of the
wave brushes by. Max temps will gradually cool over the weekend as
heights fall and cold front eventually drops south through the
region on Sun, though readings will still be above average into
Sunday afternoon.


.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1102 PM MDT Mon Mar 19 2018

Drier and warmer northwesterly to zonal upper flow will
allow VFR conditions to develop over the KALS...KCOS
and KPUB taf sites during the next 24 hours.
