.SHORT TERM...(Today and tonight)
Issued at 426 AM MDT Fri Mar 27 2020

...High fire danger this afternoon...

Currently...satellite imagery indicates low stratus, stretching from
El Paso County, southeast into Kiowa County early this morning.
Moisture is pooling along a boundary, roughly along Highway 50.
Patchy fog may be possible north of this boundary this morning.
Winds are light northerly to easterly north of the boundary.  To the
south of Highway 50, southwesterly winds are gusting in places to
near 20 mph helping to keep temperatures on the warmer side, with
40s to lower 50s.  Humidity recoveries south of Highway 50 have been
poor.  This will help in the development of high fire danger for
this afternoon.

Today...an upper level storm system is forecast to begin moving
across Colorado by this afternoon.  Ahead of this storm, flow will
increase out of the southwest.  Temperatures are expected to rise
into the upper 60s to lower 70s across the Plains for this
afternoon.  Wind will also mix down to the surface, allowing for
gusty conditions and a drying of the lower levels.  This will lead
to very high fire danger this afternoon across the Plains, with
winds gusting in excess of 30 mph and widespread humidity values
under 15 percent.  Outdoor burning should be avoided.

Precipitation is forecast to move into the Continental Divide by
late morning.  Southwesterly flow will favor initial development
over the San Juan Range, spreading north into the Central Mountains
by the afternoon.   A few snow showers will likely move into the
Eastern Mountains late this afternoon, with  high resolution models
moving a few showers off the Ramparts into the Colorado Springs area
this afternoon.  Showers that do move off the Rampart Range will
likely produce light rainfall over El Paso County.

Tonight...the upper level storm system is forecast to wrap up over
the Eastern Plains and shift east into western Kansas by Saturday
morning.  Models in good agreement with a cold front dropping south
across the Plains by midnight.  High-resolution model data suggests
a few rain, mixed with snow showers will likely accompany the front
south.  Given the expected northwesterly flow behind the system, any
showers that do impact the Plains should remain north of Highway 50.
No snow accumulations are expected on the Plains.  As for the
Mountain areas, snow accumulations through Friday into Saturday
morning will likely be in the 2 to 5 inch range, with the highest
amounts forecast over the San Juan Range.  Areas over the Palmer
Divide may see 1 to 2 inches Friday night.  Mozley

.LONG TERM...(Saturday through Thursday)
Issued at 426 AM MDT Fri Mar 27 2020

.Saturday...Cyclone moves towards the northeast during the day.
Some light precipitation may linger in the far eastern counties
during the morning. Main effect on the weather will be gusty
northwest winds over the plains. Increased wind speed above the
NBM values to be closer to MOS guidance. There is not much cold
air behind this system so temperatures will be near seasonal
values.

.Sunday and Monday...Next system starts approaching Colorado
during the day on Sunday with precipitation moving into the
Continental Divide Region. QPF amounts will be light with
snowfall amounts of a few inches over and near the Continental
Divide through Monday. The trough passes over eastern Colorado
during the day Monday. The EC, GFS and ensembles show the system
being progressive across the state and cutting off over Kansas.
This solution would keep the moisture from wrapping westward into
Colorado. Operational GFS and EC suggest an inverted trough north
of the developing surface low, and my experience has been the
inverted trough keeps the moisture to the east of the region.
Current QPF grids have only some light amounts over the eastern
Mountains. System is relatively mild with near seasonal
temperatures.

.Tuesday through Thursday...Westerly flow aloft develops over the
state with mostly dry and mild weather. Weak cold front could move
over the region later in the period. --PGW--

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1159 AM MDT Fri Mar 27 2020

For KALS, Gusty southwest winds in excess of 35 knots at times
are expected into this afternoon, otherwise VFR conditions are
expected to prevail during the next 24 hours.

For KCOS and KPUB, VFR conditions are expected to continue this
afternoon, with gusty winds around 30 knots at times also
possible. Then, gusty northerly component winds are expected this
evening as front moves through, bringing increasing precipitation
chances tonight in advance of drier conditions returning Saturday.
