Area forecast discussion...updated 
National Weather Service Albuquerque nm
650 PM MDT Thursday Jul 24 2014

decreased probability of precipitation and skycover in many locations based on recent
satellite and radar trends. Dry air wrapping into a strong upper
high from the NE will limit convection.



Previous discussion...545 PM MDT Thursday Jul 24 2014...
this evening/S thunderstorms and rain coverage among the lowest of the monsoon
season thus far. The focus for a few rain showers/thunderstorms and rain through 05z-06z
limited to The Four Corners and near and just west of the
northern Sacramento Mountains. Storm motions toward the NE at
around 10 kts in The Four Corners...and generally toward the west
over the SC mountains. Will include brief temperature at kfmn for early
to middle evening...with vc placeholder at kgup. No mention of thunderstorms and rain
at other taf sites this period. Outside the very limited thunderstorms and rain
activity...VFR conditions to prevail tonight through Friday. High
pressure aloft elongated east-west over the state will continue to limit
thunderstorms and rain activity Friday PM but overall coverage should trend upward
for the northwest/NC mountains Friday PM. Kj


high aloft now centered over nm and looks to stay over or extremely
close to the state through at least Sunday or Monday. Also its
axis will stretch more from west to east by Friday which will limit
very much moisture from seeping into the state from the south.
Steering flow will become generally west to east over the north
quarter or perhaps third of the state allowing at least a few
storms to impact the northern tier of nm by the afternoon as southern
edge of what is left of the monsoon plume skirts the north.
Expecting no or just a very few storms elsewhere. Had to back off
and shrink back probability of precipitation additional to some degree for tonight into
Sat based both on how little activity has developed through 3 PM
in the state and what the latest forecast model runs are implying.
Temperatures will likely rise a few more degrees at least across central...
south and eastern areas Friday and or Sat with this reorienting of
the upper high. In fact Sat will likely feature triple digit high
temperatures over a good portion of the eastern tier of the state with
mostly low to moderate storm chances across generally the north
and west...less so elsewhere. Between late Sat and sun a back door
front is expected to make some inroads into nm with more forecast
models than not making the case for deeper penetration of said
front...or a reinforcement...late sun into Monday. Behind this front
will be significantly higher dewpoints...cape...and directional
wind shear. Kept probability of precipitation up mostly as previous to reflect this...
meaning a significant if not dramatic increase in rain coverage .

Yet another back door boundary looks like a pretty good
possibility later Tuesday or Tuesday night providing another incentive for
increased showers and storms for midweek. There is still some
uncertainty as to how much real estate in the state any of these
fronts will be able to manage but at least 1 or 2 should at least
breach the Central Mountain chain...if not make it all the way into
west nm.



Fire weather...
no significant changes made to the gridded forecast. Humidity values
fell today due to a more stable and drier airmass over the forecast
area. The main monsoonal moisture plume will remain across the far
west or northwest through at least Friday. Best chance of wetting
rain would be found over that area although the footprint would be
small. Lowest relative humidity values areawide will most likely be Friday. A
little bit of some moisture seepage Saturday. Gustier southwest
breezes across the northeast and east Central Plains this afternoon
will lower early this evening. Cant rule out isolated red flag
conditions through the remainder of the afternoon but localized. The
affected area has also received some Greenup due to previous wetting
rains. Less wind for Friday and Saturday due to weaker Lee side
troughing. Outflow wind would remain the biggest concern but short
lived. Temperatures will remain above normal...both day and night
through Saturday.

High confidence for a prolific moisture push Sunday via a back door
cold front. Cooling from east to west Sunday through the earlier
half of next week. This means near normal temperatures...if not below
normal during the afternoons for a few days. Humidity values and cloud
cover would certainly increase during this period. Reinforcing back
door cold front is expected by midweek. Wetting rain chances will
increase substantially Sunday through Wednesday and favor the north
central mountains. Secondary area could be the Continental Divide
but will depend on where the main monsoonal plume ends up. The upper
high is still expected to shift north and westward next week but
would be gradual. When this occurs....eastern half to two thirds of
the forecast area will be favored for daily rounds of wetting
storms. Confidence is pretty good for the pattern change by next



18z taf cycle
less storm coverage during afternoon/evening compared to
yesterday. Direct impacts of sh/ts are most likely at fmn where
monsoon plume would be. A good chance of impacts at gup and little
to no chance at the other terminal sites. Gusty outflow winds to
30kt and even higher biggest threat across the west/north due to
ts/sh. Perhaps some brief mountain top obscured across the far northwest.
Lessening activity after midnight although cant rule out some
impacts past midnight across far northwest due to monsoon plume
