DISCUSSION
ISSUED AT 1040 PM MDT THU AUG 28 2025
SEEING SOME ISOLATED TO WIDELY SCATTERED SHOWERS TRYING TO
PERCOLATE AGAIN IN SW NEW MEXICO, AND CAN'T RULE OUT ANOTHER
LITTLE TRAY MAKING IT IN CLOSE TO ELP AS OUTFLOW BOUNDARIES MOVE
IN FROM THE NORTH AND WEST IN THE NEXT FEW HOURS. BEST CHANCE FOR
MEASURABLE RAIN WILL BE IN AN ARC FROM THE BOOTHEEL UP INTO THE
GILA AND ACROSS SIERRA COUNTY.
HEADING INTO TOMORROW (FRI), THE SUBTROPICAL RIDGE WILL BE
CENTERED OVER SE NEW MEXICO, WITH DEEPER MID-LEVEL MOISTURE
GETTING PULLED UP IN SW NEW MEXICO ON SOUTHERLY FLOW. MID-LEVEL
TEMPERATURES LOOK TO COOL SLIGHTLY, TO AROUND -5 TO -6C. EXPECT
CONVECTION WILL BE MOSTLY BASED IN THE HIGHER TERRAIN IN THE
EARLY AFTERNOON, THEN SPREAD TO THE DESERT MOUNTAIN RANGES LATE IN
THE AFTERNOON. A SHORTWAVE TROUGH WILL GRAZE NORTHERN NEW MEXICO
IN THE EVENING HOURS, LOWLAND THUNDERSTORM CHANCES WILL RAMP UP,
AND LOOK TO PERSIST WELL INTO THE OVERNIGHT HOURS. THIS IS
SUPPORTED BY MOST HREF MEMBERS AND THE EXPERIMENTAL REFS.
LOCALIZED HEAVY DOWNPOURS WILL BE POSSIBLE.
BY SATURDAY, PWAT VALUES WILL RANGE FROM AROUND 1.25 TO 1.50
INCHES ACROSS THE AREA, AND THE RISK OF LOCALIZED FLASH FLOODING
WILL INCREASE, ESPECIALLY ACROSS THE SACRAMENTO MOUNTAINS AND GILA
REGION STARTING IN THE AFTERNOON. ONCE AGAIN LOWLAND PRECIP
CHANCES LOOK TO HANG ON INTO THE NIGHT ACROSS THE LOWLANDS
SATURDAY NIGHT, AIDED BY UPPER LEVEL DIFFLUENCE WEST OF THE
SUBTROPICAL RIDGE.
FOR SUNDAY, SOME DRIER AIR LOOKS TO SNEAK IN ACROSS THE NORTHERN
2/3RDS OF NEW MEXICO, WITH LOW LEVEL MOISTURE POOLING ACROSS
SOUTHERN PORTIONS AS LOW LEVEL EASTERLY FLOW PULLS IN A HIGHER
DEWPOINT AIR MASS. PRECIP CHANCES LOOK TO BE HIGHEST ACROSS
SOUTHERN PORTIONS, BUT A LOT WILL DEPEND ON HOW OVERNIGHT
CONVECTION EVOLVES SATURDAY NIGHT.
MONDAY INTO TUESDAY, THE SUBTROPICAL RIDGE WILL BE REDEVELOPING
OVER THE GREAT BASIN, WHILE COOLER AND DRIER AIR FLOWS DOWN THE
GREAT PLAINS ON THE BACKSIDE OF TROUGH OVER THE GREAT LAKES.
EXPECT A DOWNTURN IN CONVECTION DURING THIS TIME FRAME, WITH SOME
IMPROVEMENT POSSIBLE BY LATE IN THE WEEK.
AVIATION
(06Z TAFS)
ISSUED AT 1040 PM MDT THU AUG 28 2025
STRAY CONVECTIVE SHOWERS ARE STILL HOLDING ON, ESPECIALLY IN SW
NEW MEXICO, BUT PROBABILITIES OF IMPACTS AT TERMINALS ARE MINIMAL.
EXPECT THE USUAL DIURNAL THUNDERSTORM TRENDS ON FRIDAY, BUT AS AN
UPPER LEVEL DISTURBANCE GRAZES NORTHERN NEW MEXICO LATE IN THE DAY
AND INTO THE OVERNIGHT HOURS, LOWLAND SHOWERS AND THUNDERSTORMS
LOOK TO PERSIST WELL INTO THE EVENING.
FIRE WEATHER
ISSUED AT 1123 AM MDT THU AUG 28 2025
MOISTURE WILL BE ON THE INCREASE INTO THE WEEKEND WITH FAIRLY
WIDESPREAD PRECIPITATION EXPECTED. RAINFALL AMOUNTS OF SEVERAL
INCHES ARE POSSIBLE IN THE HIGHER TERRAIN, ESPECIALLY EASTERN
SLOPES OF THE SACRAMENTO MOUNTAINS. TEMPERATURES WILL BE WARMEST
FRIDAY WITH 90S WITH RH'S IN THE 20S OVER THE LOWLANDS, BUT BY
SUNDAY, ALL AREAS WILL COOL DOWN INTO THE 80S WITH MIN RH'S RISING
INTO THE 30S AND 40S. RAIN CHANCES DROP EARLY NEXT WEEK, BUT WILL
