Flash Flood Warning 53, NWS Albuquerque, NM

Area Forecast Discussion
National Weather Service Albuquerque NM
140 PM MDT Sat Jun 3 2023

...New SYNOPSIS, SHORT TERM, LONG TERM, FIRE WEATHER...

.SYNOPSIS...
Issued at 136 PM MDT Sat Jun 3 2023

While the threat of severe weather diminishes this weekend across
eastern NM, the threat of locally heavy rainfall producing flash
flooding increases. This will be especially true each afternoon
for recent burn scars along the central mountain chain. Steering
flow pushing storms will weaken allowing moderate to locally heavy
rainfall to stay over one location for a longer period of time.
Storm coverage also trends higher over western and central NM
through Tuesday, likely peaking in coverage Monday and Tuesday.
Thereafter, drier southwesterly to westerly winds being pushing
into western NM. Storm coverage trends down west to east across NM
Wednesday to Friday with dry, warm/hot, and breezy afternoons
favoring most areas by Friday.

.SHORT TERM...
(This evening through Sunday night)
Issued at 136 PM MDT Sat Jun 3 2023

First this is your daily reminder that no, this is not the NA
Monsoon starting early. We still have westerly flow aloft and have
not see a change in the upper level wind flow to signal the monsoon.
It is a continued wet/moist pattern that is very different from the
last few years.

Upper level pattern has weakened with an upper low over the Great
Basin and a shear axis stretching from the upper low into the
Plains. This leaves weak 10-20 kt mid level flow over New Mexico
from the west/northwest. Storm motions have greatly slowed down
compared to the last few days and the lack of deep layer shear will
limit thunderstorm organization and severe potential. SPC has a
marginal risk for much of E NM and based on there being some
instability remaining this afternoon. Convection initiated early
this afternoon over the higher terrain from the northern mountains,
Continental Divide, Gila Forest and Sacramento mountains. Burn scar
flash flooding will be closely monitored not only today and tomorrow
but also for much of next week. ML-CAPE today is only expected to be
1000-2000 J/Kg and that is looking pretty reasonable given storm
morphology so far with the limited shear. Storms remain quite pulse
like and become outflow dominated. These trends should continue the
rest of the afternoon. A storm could become severe briefly with
hail/damaging winds if it can fully take advantage of instability
and low level convergence.

Tonight the main concern in the forecast will be the potential for
any outflows to push from E NM back to the west through the central
mountains creating cap winds for the RGV. Right now models suggest
25-30kt wind gusts but confidence is low since it hinges on not only
just outflow developing but a strong enough cold pool to push the
gust front through the mountains.

Tomorrow conditions look very similar when compared to today except
for some subtle differences. Upper level flow becomes weaker still
as upper level ridging builds some over New Mexico. There will still
be some resemblance of NW flow aloft over the northern mountains so
convection over the HPCC burn area will be a concern.

&&

.LONG TERM...
(Monday through Friday)
Issued at 136 PM MDT Sat Jun 3 2023

Monday begins the long term period with continued daily rounds of
afternoon convection initiating over the high terrain of western
and central NM. Convective outflow from Sunday evening is still
being modeled to push moisture further west to or past the
Continental Divide. This will set the stage for scattered to even
numerous cells developing over the Gila NF and Continental Divide
up to Mt. Taylor Monday afternoon. The main focus will continue to
be storms initiating along the central mountain chain over recent
burn scars. With the axis of a upper level ridge of high pressure
aligned N-S over the Rio Grande Valley, storm motions will be a
bit slow. This will increase the risk of localized flash flooding,
especially over area burn scars early Monday afternoon. Steering
flow will be weak, but still present drifting storms east over the
eastern plains and highlands late day. Storm motions along and
west of the Rio Grande Valley will be more erratic with new cells
developing along colliding outflow boundaries. Storms slowly taper
off through Monday night with convective outflow pushing
increased low-level moisture further west to the AZ border by
Tuesday morning.

The recent 12Z model trend shows drier southwesterly winds
associated with a 566dm H5 upper low off the southern CA coastline
pushing into southwestern NM earlier than prior runs. Have trimmed
PoPs lower for that area of the forecast area Tuesday afternoon
and evening as a result. The overall forecast still features the
ridge of high pressure squarely over NM with afternoon storms
initiating over the central mountain chain with slow storm
motions. Another round of localized heavy rainfall producing flash
flooding, especially over recent burn scars, will result Tuesday
afternoon. The drier southwesterly flow pushes deeper into central
NM to the Rio Grande Valley by Wednesday and Thursday. Afternoon
thunderstorm activity trends down west to east each day as a
result. By Friday, nearly all of the forecast area except far
northeastern NM and the northern Sangre’s will favor dry and
breezy conditions.

.AVIATION...
(18Z TAFS)
Issued at 1119 AM MDT Sat Jun 3 2023

The upper level flow has weakened today compared to the last
couple of days now with an upper low over the Great Basin and a
shear zone stretching from it towards Colorado and then into the
plains. This still supports W/NW flow aloft and slow storm motions
to the E/SE. Convection has already initiated across the high
terrain of New Mexico so now it is just a matter of how it
evolves. CAMs show bulk of the activity over the northern
mountains into the Highlands/NE NM. KSAF/KLVS/KTCC/KROW all have
higher chances of storms this afternoon but KFMN/KGUP/KAEG/KABQ
all have a small chance at dry storms with weak downburst winds.
TAFs reflect these convective trends through this afternoon/evening.
After 06Z tonight convection should be done. Look for a repeat of
these conditions for Sunday.

&&

.FIRE WEATHER...
Issued at 136 PM MDT Sat Jun 3 2023

Increased thunderstorm activity through the middle of next week will
limit any elevated/critical fire weather conditions due to the
influx of moisture over much of New Mexico. Most storms should
provide wetting rains limiting the potential for dry lightning
strikes and fire starts. Looking at the RFTI data the only chance of
having anything close to elevated or critical conditions may be on
next Thursday and Friday in western/central New Mexico. That might
be the next time frame that dry air from the SW/W moves into New
Mexico behind a trough.

The other issue to have concern over will be gusty/erratic winds
from thunderstorm outflows each day. Wind gusts in the 30-40 mph
range may cause issues for any prescribed burns in the area. Since
storms have been initiating in the early afternoon or even late
morning, the time window for any burns will be small.
