DISCUSSION
ISSUED AT 247 AM MDT MON MAY 5 2025
LARGE OMEGA HIGH PRESSURE PATTERN DEVELOPING OVER THE LAST COUPLE
OF DAYS IS WELL ENTRENCHED OVER MUCH OF THE NATION. UPSTREAM
ANCHOR LOW OVER ARIZONA WILL SLOWLY LIFT NORTHEAST THROUGH
TUESDAY AS OMEGA PATTERN BREAKS DOWN. THIS SLOW LIFTING OUT OF THE
LOW WILL CONTINUE TO PROVIDE MODEST LARGE SCALE LIFTING BOTH TODAY
AND TUESDAY. MEANWHILE AT THE SURFACE, DEWPOINTS HAVE DROPPED
ABOUT 20 DEG MOST AREAS EXCEPT THE FAR EAST. DESPITE THIS SOME
MARGINAL INSTABILITY WILL PERSIST BOTH TODAY AND TUESDAY. THUS
WILL KEEP ISOLATED SHOWERS/THUNDERSTORMS IN BOTH DAYS; AS USUAL
FAVORING THE MOUNTAINS A BIT. DEWPOINT DEPRESSIONS TODAY OVER THE
MOUNTAINS WILL APPROACH 40 DEG, THUS CAN'T RULE OUT A DRY
LIGHTNING STRIKE OR TWO. POPS SOMEWHAT HIGHER ON TUESDAY AS
DEWPOINTS INCREASE SOME. ALSO, CAN'T FORGET, SNOW LEVELS WILL FALL
TO AROUND 7500-8000 FT TONIGHT SO A DUSTING OF SNOW IS POSSIBLE AT
THOSE HIGHER ELEVATIONS.
WEDNESDAY AND THURSDAY...ANCHOR LOW LIFTS OUT OF AREA AS OMEGA
PATTERN HAS COMPLETELY BROKEN DOWN. HOWEVER ALL THREE OF
GFS/NAM12/ECMWF SHOWING SECONDARY LOW DEVELOPING OVER THE GREAT
BASIN AND MOVING DOWN OVER ARIZONA WEDNESDAY. LOW THEN LIFTS OUT
NORTHEAST OVER NEW MEXICO WEDNESDAY NIGHT AND THURSDAY. THUS, WILL
HAVE TO KEEP LOWER POPS IN BOTH DAYS, MAINLY OVER THE MOUNTAINS
WITH MARGINAL INSTABILITY CONTINUING. A WEAK BACK DOOR FRONT DOES
MOVE INTO THE EASTERN CWA THURSDAY MORNING, BUT WITH VERY
LITTLE/NO COOL ADVECTION.
FRIDAY INTO SUNDAY...STRONGER EAST SURGE DOES PUSH MORE MOISTURE
(LIKELY WITH DRY-LINE) INTO THE AREA THROUGH THIS PERIOD.
DEWPOINTS RISE BACK UP INTO THE 40S AND PWS CLIMB BACK TO AROUND
.60-.80 INCHES. INSTABILITY WILL INCH BACK UP, BUT LARGER SCALE
LIFT LOOKS TO BE ABSENT AS WEAK RIDGING DEVELOPS ALOFT. STILL,
LOOKS TO BE A SLIGHTLY BETTER CHANCE OF SHOWERS/THUNDERSTORMS AREA
WIDE. SEASONABLY COOL TEMPERATURES LEADING INTO THIS PERIOD WILL
WARM BACK ABOVE NORMAL TO END THE WEEKEND.
AVIATION
(12Z TAFS)
ISSUED AT 535 AM MDT MON MAY 5 2025
GENERALLY VFR CONDITIONS THROUGH THE PERIOD. SKC-SCT250 THIS
MORNING. FROM DEMING-T OR C WEST...INCREASING SCT-BKN080 BKN200
WITH ISOLATED BKN050 -SHRA DEVELOPING AFTER 15Z. AFTER 18Z FEW
BKN050CB -TSRA POSSIBLE, MAINLY OVER THE GILA/BLACK RANGE. THESE
CONDITIONS SPREADING FURTHER EAST ACROSS SIERRA AND NORTHERN
OTERO/SACRAMENTO MTNS AFTER 20Z. SURFACE WINDS INCREASING TO
SOUTHWEST 15-20G30 KNOTS AFTER 15Z. WINDS DIMINISHING TO WEST 7-10
KNOTS AFTER 03Z.
FIRE WEATHER
ISSUED AT 247 AM MDT MON MAY 5 2025
FIRE CONDITIONS MOSTLY REMAINING ELEVATED DUE TO LOW FUEL MOISTURE
AND BREEZY AFTERNOON. THE RISK OF THUNDERSTORMS WILL EXIST MOST OF
THIS PERIOD THROUGH SUNDAY WITH CHANCES INCREASING FOR THE
WEEKEND. SOMEWHAT LARGE DEWPOINT DEPRESSIONS TODAY COULD LEAD TO
DRY LIGHTNING STRIKE OR TWO. AND OF COURSE ERRATIC WIND GUSTS ARE
ALSO LIKELY NEAR STORMS. SIGNIFICANT WIND SHIFT BACK TO
EAST/SOUTHEAST THURSDAY THROUGH SUNDAY WILL ALSO INCREASE LOW
LEVEL MOISTURE AND HENCE, THE INCREASING CHANCES OF RAIN.
MIN RH: LOWLANDS 13-18% TODAY INCREASING TO 20-30% TUESDAY, THEN
13-20% WEDNESDAY THROUGH SUNDAY. MOUNTAINS 20-30% TODAY INCREASING
TO 30-40% TUESDAY, THEN 18-25% GILA WEDNESDAY THROUGH SUNDAY; AND
30-45% SACRAMENTO MTNS WEDNESDAY THROUGH SUNDAY. VENT RATES VERY
GOOD-EXCELLENT ALL DAYS EXCEPT THURSDAY WHICH IS FAIR-GOOD.
