SOUTHEASTERN RIO ARRIBA COUNTY...

AT 235 PM MDT...LOCAL LAW ENFORCEMENT REPORTED FLASH FLOODING IN FAR
SOUTHEASTERN RIO ARRIBA COUNTY...NAMELY BETWEEN
CHILI...CHAMITA...AND ALCALDE WHERE MULTIPLE VEHICLES HAVE BEEN
STALLED OR OVERTURNED DUE TO FLASH FLOODING. RADAR ESTMATES TWO TO
THREE INCHES OF RAIN HAVE ALREADY FALLEN WITH ADDITIONAL STORMS
REDEVELOPING OVER THE WARNED AREA. .

LOCATIONS IMPACTED INCLUDE...
ESPANOLA...VELARDE...OHKAY OWINGEH PUEBLO...LYDEN...HERNANDEZ...LA
VILLITA...CHILI...CHAMITA AND ALCALDE.

ADDITIONAL RAINFALL AMOUNTS OF ONE HALF TO AN INCH ARE POSSIBLE IN

PRECAUTIONARY/PREPAREDNESS ACTIONS...

STAY AWAY OR BE SWEPT AWAY. RIVER BANKS AND CULVERTS CAN BECOME
UNSTABLE AND UNSAFE. DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE
WATER COVERS THE ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW
YOUR CAR TO CROSS SAFELY.

TURN AROUND...DONT DROWN WHEN ENCOUNTERING FLOODED ROADS. MOST FLASH

Area Forecast Discussion...UPDATED
National Weather Service Albuquerque NM
1146 AM MDT MON AUG 22 2016

.AVIATION...
18Z TAF CYCLE
Moist/unstable atmosphere to support another round of SCT to
NMRS SHRA/TSRA with localized MT top obscurations and MVFR/IFR
conditions. Early Cb development over the higher terrain underway
and convective temps are a few degrees lower as compared to 24
hours ago. As a result, expect potential impacts to develop more
abruptly as surface heating increases next several hours. Storm
motions will be a little faster and broadly SW to NE as compared
to Sunday. Shifted the start time for VCTS placeholders at
central/western TAF sites an hour earlier and maintained tempo
SHRA for now. Overall, impacts at FMN, GUP, SAF, LVS, and ABQ
appear to be more focused during the 20z-01z window with less
organized convective activity in the evening central and west.
Will watch for convective lines across east-central and southeast
areas after 01z. 41/34

.PREV DISCUSSION...351 AM MDT MON AUG 22 2016...
.SYNOPSIS...
A continued moderately to very active weather work week is ahead
with shower and storm coverage varying from fair to very good with
Thursday arguably the greatest coverage day and the least coverage
day on average areawide being somewhat less apparent. With the
exception of a good portion of the east on Tuesday, below normal
afternoon temperatures will be the rule. Multiple weak to moderate
strength troughs or even weak closed low pressure circulations
aloft will rather slowly approach and move across the state
through Thursday, while yet another cold front will push from
northeast to southwest across the state between Wednesday and
Thursday. The latter feature will introduce additional low level
moisture to help encourage Thursday's expected peak rain coverage.

&&

.DISCUSSION...
Weak low pressure will gradually open up into a trough and
continue its slow approach toward NM through this evening and,
most fcst models agree, will be trailed by another one even more
slowly approaching the state for the Wed to Thu period. Satellite
loops still show some drying aloft entering far sw NM and that,
along with the slow approach of the aforementioned initial weak
low is generating some pre dawn light to moderate showers in and
near the Gila region. It appears that the most active portion of
the state today should be the northern mtns and perhaps southward
across and just east of the higher terrain and into the south
central mtns. Decided at the last minute to tone down PoPs and QPF
somewhat across and immediately adjacent to the Gila region this
aftn to account for a little more drying introduced at the base
of the trough into that area, tho still retaining some healthy
PoPs.

The trailing mid-level trough which may even approach as a weak
closed low for the Wed to Thu period still may actually
temporarily stall over the state for later Wed/Thu or even drift
somewhat to the south as it enters the state. Both the 00z GFS and
ECMWF are indicating that scenario to a fair degree. That and the
back door front should encourage and even more active period.

Extended models for the most part still indicating some decent
drying as the weekend and early next week come to pass, but latest
ECMWF is much slower with the high building in from the west and
thus keeps much more precip in, espec east and south.

&&

.FIRE WEATHER...
Weather pattern appears to be consistent with a gradual downtrend in
the wetting rain footprints next couple days. Then a trend upwards
late Wed into Thur thanks to a back door cold front. Moisture would
begin to recycle back out Fri into the weekend although this could be
a slow process depending on the upper low to the west. A quick peak
into next week suggests a drying/warming trend based on the upper
high position. Confidence is low to moderate that far out at this
time for next week.

Despite a gradual lowering trend in RH the next couple of
days...humidity values will be on the higher side. Perhaps more
seasonable levels on Tue. Wind speeds look to be unusually strong
this afternoon across the NE third and went a little higher compared
to previous gridded forecasts. Lee side surface low looks to be
quite strong for this time of year and will be supported by a
strengthening flow aloft due to the ejection of a weak shortwave
trough. Storm movement will be quicker the next couple of days thus
leading to lessening wetting rainfall footprints overall. Gusty
breezes will remain Tue afternoon although appear to be less
compared to this afternoon. As a result of the higher transport wind
speeds...vent rates appear to be on the higher side Mon-Tue.

Back door cold front is still projected to impact portions of the
eastern plains Wed into Wed night. Storms will fire up along this
boundary push. The parent and stronger shortwave trough will also
approach the forecast area from the west at the same time the cold
front pushes into the east. The combination of these two entities
will increase wetting rain potential later Wed into Thursday.
Humidity values will tend to rise...especially on Thur. Went a
little above model guidance for gridded dewpoints thus higher
humidity due to confidence considerations. Vent rates will lower due
to the frontal influence with more poor values showing up Wed/Thu.

The main shortwave trough should be out of the area on Friday which
means residual higher moisture should recycle out in the form of
scattered wetting thunderstorms favoring the mountains. This trend
would last into the weekend as storm coverage decreases a little
each day. Humidity values should also gradually lower while
temperatures rise some. The ECMWF appears to be a little bit more
bullish in hold over wetting moisture compared to the GFS but the
overall pattern is pretty similar.

As mentioned above...building upper level ridge being depicted by
both the operational GFS/ECMWF models for next week. Suspect the
ridge building will take its time and a back door cold frontal
intrusion could delay the onset of the more significant drying. Stay
tuned.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTH AND CENTRAL
NEW MEXICO.

.DAY ONE...TODAY AND TONIGHT

SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED MAINLY THIS
AFTERNOON INTO THE EVENING HOURS. RAINFALL MAY STILL BE LOCALLY
HEAVY WITH SOME STORMS...MAINLY ACROSS THE WESTERN TWO THIRDS OF
NEW MEXICO...BUT THE CHANCE OF HEAVY ENOUGH RAIN TO CAUSE FLASH
FLOODING OR HIGH AND FAST FLOWS IN ARROYOS AND SMALL STREAMS IS A
LITTLE LESS THAN WAS THE CASE SUNDAY. BURN SCARS AND LOCALES
IMMEDIATELY BELOW THEM WILL REMAIN THE MOST AT RISK FOR VERY
LOCALIZED FLOODING. A FEW STORMS MAY ALSO PRODUCE SMALL HAIL AND
WIND GUSTS TO 50 MPH.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

WHILE COVERAGE OF THUNDERSTORMS SHOULD BE SLIGHTLY TO MODERATELY
LESS TUESDAY INTO WEDNESDAY MIDDAY...LATE WEDNESDAY THROUGH FRIDAY
MAY BRING ANOTHER SIGNIFICANT INCREASE IN SHOWERS AND STORMS
ACROSS MUCH OF THE FORECAST AREA. STORM MOTIONS MAY WELL BE SLOW
ONCE AGAIN AND RAINFALL COULD BECOME HEAVY. THIS MAY LEAD TO
LOCALIZED AREAS OF FLASH FLOODING...ESPECIALLY OVER AND NEAR
RECENT AND OLDER BURN SCARS. ISOLATED LOCATIONS MAY RECEIVE UP TO
2 INCHES OF RAINFALL. A FEW STORMS MAY ALSO PRODUCE SMALL HAIL AND
WIND GUSTS TO 50 MPH.

SPOTTERS ARE ENCOURAGED TO REPORT RAINFALL AMOUNTS AND ANY FLOODING
THROUGH THE NATIONAL WEATHER SERVICE ALBUQUERQUE WEB SITE AT
