Area Forecast Discussion
National Weather Service Albuquerque NM
353 PM MST Sat Feb 18 2017

.SYNOPSIS...
Precipitation will increase across western areas tonight into Sunday
as the upper level low inches toward the state. Look for snow showers
above 8000 feet with rain showers below 7000 feet. A drier, warmer
pattern will return Monday as upper level ridging takes fold
allowing the return of above normal temperatures through midweek.
Conditions will turn windier and cooler toward the end of the week
as a cooler upper level system crosses the Rockies.

.DISCUSSION...
Rich moisture advection will continue surging northward as the upper
level low, currently over the Baja Peninsula inches closer to the
state. Wetting precipitation will develop across western areas this
evening with snow showers beginning across the SW mtns. Advisory
level snow showers will focus across the SW and San Juan Mtns late
tonight through Sun evening. Snow fall accumulations above 7000
feet will range from 5 to 8 inches with higher amounts near mtn
peaks as snow levels lower to 6500 to 7000 ft overnight. By Sun
morning, snow showers will develop across portions of the northern
mtns favoring the San Juans. Meanwhile, lower elevation rain showers
will favor much of western and central NM through late Sun. I still
mentioned thunder chances in the wx grids for areas along and west
of the central mtn chain Sunday aftn because of the NAM12 displaying
some areas of instability. Meanwhile, temperatures will trend below
normal central and west Sun before rebounding Mon.

By Mon, an upper level ridge axis will center over the state allowing
drier and warmer conditions to return. Temperatures will rebound
quickly Mon and Tues to above normal readings. Of course warmer
readings will be felt across the eastern plains with aid from some
lee side troughing. Westerly winds will increase Wed as upper level
flow becomes stronger and zonal which could increase fire weather
concerns across the eastern plains Wed aftn but some mid level
moisture creeping in from the west...increasing high clouds could
hinder fire development. The next incoming system will be cooler and
windier as it crosses the Colorado Rockies. We could definitely
expect an active wind event Thurs aftn across much of the state.
Temperatures will cool below normal as the system departs Friday but
they look to warm back above normal by the following weekend.

.FIRE WEATHER...
Moisture advection is underway as an upper low over the northern
Baja approaches. Chances for wetting precipitation will ramp-up
tonight and continue into Sunday night, favoring the western higher
terrain. Moderate snow accumulation is likely above 8000ft, with
wet/melting snow below and mostly rain below 7000ft. QPF has trended
down from yesterday, so the extent of this wetting event has been
scaled-back somewhat.

A ridge builds-in quickly Monday behind the departing trough and
begins a new warming/drying trend that will last into mid week.
Daytime temperatures will be back above normal areawide by Tuesday.
Vent rates will trend down under the ridge, but have trended up from
previous forecast cycles. Vent rates will be good to excellent most
areas by Wednesday as the ridge shifts east and the westerlies
increase with a deepening lee side trough. Elevated fire weather
conditions are looking more likely Wednesday afternoon across
portions of the Eastern Plains with Haines values of 5 and critical
to near critical humidity. However, moisture advection in the mid
levels of the atmosphere Wednesday will create a thickening cloud
layer and would potentially limit fire behavior. Still looking like
a solid wind event Thursday with potential for critical fire weather
conditions, but cold air advection and clouds may limit fire
behavior everywhere except the Lower Rio Grande Valley and East
Central Plains.

A bit of a cool-down in the wake of the departing system Friday,
followed by a warm-up next weekend in advance of another upper
low/trough. Both the 12z ECMWF and GFS show limited wetting
potential with that system as they both open-up a deep low over
Southern California and swing in quickly eastward late Sunday into
the following Monday.

.AVIATION...
18Z TAF CYCLE
VFR conditions prevail, with lowering VFR cigs forecast then
deteriorating conditions overnight. MVFR cigs will develop tonight
across western New Mexico with the onset of precipitation and may
briefly lower to IFR at KFMN/KGUP early Sunday morning. Brief MVFR
cigs in rain also possible Sunday morning at KABQ, KAEG and KSAF.
Mountain obscurations will develop late today and become widespread
overnight into early Sunday.
