Area Forecast Discussion
National Weather Service Albuquerque NM
310 PM MDT Thu Aug 10 2017

.SYNOPSIS...
Showers and thunderstorms will become more widespread and active
Friday and through the weekend before some drying pushes into west
central and northwest New Mexico early to mid next week. A few
strong to severe storms with large hail and damaging wind gusts are
most likely late this afternoon and evening over portions of
northeast New Mexico. Locally heavy rain on Friday, which could
result in flash flooding, may be most likely along portions of the
central mountain chain, Northeast and Central Highlands and the East
Central Plains. High temperatures for the next several days will be
near to below average while overnight lows will be near to above
average.

&&

.DISCUSSION...
Sure doesn't seem like the monsoon season with the recent bouts of
severe weather and the ongoing SPC outlook, which still has the
marginal/slight risk area painted over Union, and the majority of
Catron and Harding counties through this evening. Sfc front/outflow
boundary forecast to surge into the northeast, but latest HRRR has
delayed it until 00Z or after. This seems reasonable as convective
development just starting to get frisky over ne NM and over se CO.
Given the placement of forecast rainfall and surface gradient, not
suspecting there will be much of an east wind, if any, into the
middle/lower RGV tonight. May have to watch the southeast tonight,
if the boundary is driven farther south because the inherited
minimal to nil pops were left in that region.

The upslope flow associated with the boundary sets the stage for a
more active Friday/Friday night, and potential for heavy rain over
portions of the central mt chain, Northeast and Central Highlands
and East Central Plains, where theta-e values increase significantly.
Severe storms are not in the outlook though. Did up pops to match
the guidance consensus. The far southeast and far northwest may be
the areas which are least likely to receive decent rainfall. Lowered
high temperatures Friday for parts of the northeast, although did
not go as cool as the MET guidance.

Saturday and Sunday look active also with a rather flat H5 ridge in
place. Another front may impact the northeast Sunday night and again
Monday night. Some drier air may push into west central and
northwest New Mexico next Tuesday/Wednesday to trim rain chances
there. High temperatures the next 7 days will be near to below
average, with lows near to above average.

&&

.FIRE WEATHER...
The mid-level high pressure system will migrate southeastward over
south TX today, allowing a more traditional flow of monsoon moisture
to stream north and northeastward over the forecast area. A couple
of moist back door cold fronts area also expected to dive south
southwestward through the eastern plains: one tonight and the other
Sunday night. An uptick in the coverage and wetness of showers and
thunderstorms is expected to begin Friday, with scattered to
numerous showers and thunderstorms expected each afternoon and
evening through Monday. With PWATs in the 1-1.6 inch range on
Friday, that day should be the wettest day overall, and Monday looks
to be a close second if Sunday night's front comes in wet enough.
With all the moisture and some cool air advection with the fronts,
high temperatures will vary from near normal to several degrees
below normal Friday through Monday. Haines will vary around 3
through this period.  There will also be areas of poor ventilation
Friday and Saturday, but probably some improvement Sunday before
vent rates fall again on Monday.

An upper level trough approaching from the west will steer drier air
into the state from the west and southwest Tuesday through the
middle of the coming work week. The coverage and wetness of
convection will decrease with each day, and there will be a
resulting increase in high temperatures. Ventilation will probably
also improve, though some stubborn pockets of poor may linger over
southwest areas. Haines around 5 are expected across northern areas
Tuesday and Wednesday.

&&

.AVIATION...
18Z TAF CYCLE
The mid-level high pressure system will begin to shift SE of NM today
allowing better moisture and a more traditional monsoon flow to
develop. SCT to ISOLD storms will generally move toward the northeast
around 10-20 mph, except for NMRS cells over the southwest mountains,
and also across the NE corner (where cells should move more toward
the E or SE). Storms across the NE will be capable of large hail and
damaging winds with an ISOLD tornado threat. Cells will probably
cluster this aftn and evening, and an organized line will be possible
across the NE. A back door cold front will push southwestward
through the E plains tonight into Friday morning, allowing low clouds
with IFR and MVFR conditions into the NE quarter of the state.
Greatest confidence in TAF site flight category restriction is at
LVS Friday morning, with less confidence at TCC. Storms will increase
in coverage on Friday with locally heavy rain and wet microbursts
likely.

This hazardous weather outlook is for portions of north and central
New Mexico.

.DAY ONE...Today and Tonight

There is a marginal risk for severe thunderstorms over the northeast
plains, including Union county. Storms will be capable of producing
large hail, strong downburst winds, frequent lightning, and locally
heavy rainfall. There is a slight risk for flash flooding over north-
eastern New Mexico where locally heavy rainfall is possible.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

There is a slight risk for flash flooding over portions of north-
central and western NM Friday, including the Sangre de Cristo's,
middle Rio Grande Valley, and the SW mountains. Long duration of
locally heavy rainfall in these areas will be able to produce
localized flash flooding.

A significant moisture surge will produce a large coverage of storms
over NM Friday and through the weekend. This pattern will enhance the
possibility for locally heavy rainfall and the risk for flash
flooding.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated.
