...SIGNIFICANT HEATWAVE THROUGH THE WORK WEEK...

.SYNOPSIS...
A strong high pressure system will build back over New Mexico from
the west with a warming trend today through Thursday. Record and near
record high temperatures will initially favor central and western
areas, but will probably spread to include the southeast around mid
week. High temperatures will peak around 7 to 14 degrees above normal
Wednesday and Thursday. A string of days with triple-digit high
temperatures is expected over many lower elevation locations. The
length and intensity of this heatwave will pose a risk to public
health over central and western areas, and eventually also the
southeast. There will also be a chance for thunderstorms each
afternoon and evening through mid week with storms initially
developing over the high terrain before spreading south and
southeastward to adjacent lowlands. A broad upper level trough will
carve into the northern and central Rockies late in the week,
shifting the high pressure system south of New Mexico and sending a
moist back door cold front through the state with increased showers
and thunderstorms, and welcome relief from hazardous heat starting
Friday night.

&&

.DISCUSSION...
The center of the mid level high pressure looks to stay over central
AZ this week with a ridge axis extending eastward over east central
and southeast NM. This will allow a modest stream of low level
moisture to continue flowing into southern and eastern areas through
Wednesday with mainly isolated showers and thunderstorms over the
mountains and adjacent lowlands to the south and east. Northwest NM
will have a drier flow out of the northwest, so storms over the
northwest quarter of the state will be of the drier variety. Models
depict a series of shortwave troughs clipping northeast NM in NW flow
aloft each day today through Thursday with a few strong to severe
storms possible east of the Sangre de Cristo Mountains during the
afternoons and evenings.

The big weather story this week will continue to be the oppressive
heat, which is well underway around Glenwood, and will spread to much
more of central and western NM starting today. See the latest Heat
Advisory for more information. The heat should spread further over
southeast areas by Thursday and linger there into Friday. The mid
level high pressure center aloft now looks to sustain 594-597 DAM
through at least Thursday before weakening while shifting southward
Friday.

The aforementioned long wave trough will send a moist back door cold
front through the state from the northeast Friday. Models are in
better agreement now that the front will reach the east slopes of the
central mountain chain Friday afternoon and night. This should
produce an uptick in convection from the Sangres eastward as early as
Friday afternoon. The slower arrival of the front means the hazardous
heat will probably continue through Friday across central, western
and southeast areas.

The weekend ahead looks much cooler with a greater chance of showers
and thunderstorms pretty much areawide.

.FIRE WEATHER...
A stubborn dominant high pressure ridge will linger over western
NM/eastern AZ through the rest of the week before sliding south into
old Mexico this weekend. Remnant moisture from last weekend's
backdoor front will continue to recycle each afternoon with isolated
to scattered afternoon tstorm activity off the higher terrain.
Storms are expected to be dry over the SW with very localized rain
footprints. Gusty erratic winds and lightning will be the main
concern with any passing storm. Higher instability with Haines 6 and
drier air over western NM will be relegated to western NM today and
Wednesday before advancing over the eastern plains Thursday.

Afternoon storm activity Tuesday will once again be relegated to the
higher terrain of the central and SW mtns. High instability and high
DCAPE values over the NE plains off the Raton ridge to Clayton will
allow for the chance for severe downburst winds from the stronger
storms. Storm motion will generally be SE, with slower and more SW
motion over the Gila. Wednesday will see similar tstorm potential.
Rain chances fall to nil Thursday until a backdoor front Friday
night into Saturday morning slides through the eastern plains.

Overnight RH recoveries will be good each night until drier air
advances east Thursday. Dewpoints did trend up slightly Thursday
near the TX border...due to a potential Tropical Storm coming ashore
in SE Texas, helping to limit the advance of the dry air. Single
digit MinRHs will be relegated west of the central mtn chain until
Thursday where single digit RHs will be widespread over the state.
Vent rates will be mostly fair to good, with excellent vent rates
areawide by Thursday. Mixing hgts also rise each day to near or
above 500mb. While technically there will be no critical fire
weather conditions, it will be very dry and very hot for several
days in a row. Wind will be the one limiting factor for critical
conditions.

By the end of the week the ridge will begin to slip south into old
Mexico. Models continue to handle short-wave troughs passing through
zonal flow over the Canadian border differently, which in turn is
producing different timing for the next backdoor front. The GFS
continues to show a late Friday night arrival, with the ECM arriving
late Saturday night...making Saturday's forecast a bit problematic.
Hot and dry will hold on for one extra day on Saturday if the ECM is
correct. Either way, the front will bring relief to the oppressive
heat and increase sfc moisture to the continental divide. This will
once again allow for afternoon tstm activity over the higher terrain
early next week. Drier westerly flow could potentially push into the
state by mid next week.

&&

.AVIATION...
06Z TAF CYCLE
Lingering high cirrus from previous thunderstorm activity will clear
out tonight. Some low clouds are possible over the eastern high
plains Tuesday morning, but any MVFR/IFR ceilings will be isolated
and spotty at best, burning off after sunrise. VFR conditions are
expected areawide Tuesday with another round of isolated to scattered
showers and storms off the high terrain of the central and SW mtns.
A few storms over the NE plains could become severe where instability
will be the greatest.

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

.DAY ONE...Today and Tonight
Hazardous heat will spread to much of central and western portions of
the forecast area today as a strong high pressure system builds
overhead from the west causing a multi-day stretch of triple-digit
high temperatures. See the latest Heat Advisory for more information.

There is a marginal risk for isolated severe thunderstorms east of
the Sangre de Cristo Mountains this afternoon and evening, with large
hail and damaging wind being the main threats.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

The heatwave will continue across much of central and western New
Mexico for the remainder of the work week, and will likely spread to
the Roswell area Thursday and Friday. See the latest Heat Advisory
for more information. Temperatures will trend downward on Saturday,
as a broad upper level trough sinks southward over the northern and
central Rockies displacing the high pressure system south of New
Mexico. A moist back door cold front will also arrive late Friday
easing the excessive heat.

The marginal risk of severe thunderstorms will return east of the
Sangre de Cristo Mountains during the afternoon and evening
Wednesday and Thursday, when isolated severe thunderstorms could
again produce large hail and damaging winds.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be required east of the Sangre de Cristo
Mountains today through Thursday during the afternoon and evening if
severe storm coverage increases enough.
