DISCUSSION
ISSUED AT 144 AM MDT TUE MAR 11 2025
AN ACTIVE WEATHER PATTERN IS SHAPING UP THROUGH MOST OF THE
FORECAST PERIOD. A SERIES OF PACIFIC STORM SYSTEMS WILL BRING
PERIODS OF BREEZY TO WINDY TO AT TIMES VERY WINDY CONDITIONS TO
THE BORDERLAND. AN ANALYSIS OF SATELLITE THIS MORNING SHOWS A
CLOSED UPPER LOW PRESSURE SYSTEM OFF THE SOUTHERN CALIFORNIA
COAST. BOTH THE DETERMINISTIC GFS/ECMWF SHOW THE CLOSED UPPER LOW
COMING ONSHORE IN SOUTHERN CALIFORNIA OR THE FAR NORTHERN BAJA
PENINSULA LATE TONIGHT INTO EARLY WEDNESDAY AND RETROGRADING INTO
AN OPEN TROUGH. THE TROUGH WILL QUICKLY MOVE EASTWARD ACROSS
CENTRAL ARIZONA TODAY AND THEN ACROSS CENTRAL NEW MEXICO ON
WEDNESDAY BRINGING A MODEST INCREASE IN WEST TO SOUTHWEST FLOW ON
WEDNESDAY ACROSS THE AREA. THERE IS SOME MODEST MOISTURE
ASSOCIATED WITH THIS STORM SYSTEM THAT WILL BRING SOME MOUNTAIN
SNOWFALL WEDNESDAY MORNING WITH AROUND AN INCH OF SNOW FALL OR
LESS WITH SHOWERS IN THE LOWLAND AREAS.
ATTENTION TURNS TO THE NEXT SYSTEM ON THURSDAY, AS THE NEXT
TROUGH MOVES ONSHORE LATE WEDNESDAY NIGHT ALONG THE US WEST
COAST. THE TROUGH WILL MOVE INTO THE SIERRA NEVADA REGION BY
THURSDAY AFTERNOON, ALLOWING SOUTHWEST FLOW OVER THE AREA TO
QUICKLY STRENGTHEN BRINGING WINDY TO VERY CONDITIONS AND AREAS OF
BLOWING DUST TO THE AREA THURSDAY AFTERNOON WITH THE LIKELIHOOD OF
SEEING SOME DUST STORM WARNINGS AS THE LEE SIDE LOW STRENGTHENS
OVER EASTERN COLORADO ON THURSDAY. MODELS THEN BRING THE TROUGH
ACROSS CENTRAL NEW MEXICO THURSDAY NIGHT INTO FRIDAY BRINGING
CHANCES FOR SNOWFALL IN THE MOUNTAINS WITH THE NBM MEAN FAVORING
AROUND 2 TO 4 INCHES IN THE GILA/BLACK RANGE WITH SHOWERS IN THE
LOWLANDS WITH PRECIP AMOUNTS IN THE TENTH TO TWO TENTHS RANGE.
A SHORTWAVE WITHIN NORTHWEST FLOW WILL DIVE SOUTHEAST TOWARD THE
AREA FROM NORTHERN CALIFORNIA ON FRIDAY NIGHT. THE SHORTWAVE WILL
BRING SOME MOISTURE AND DYNAMICS MAINLY TO THE NORTHERN HALF OF
THE AREA BRING CHANCES FOR RAIN/SNOW TO AREA ON SATURDAY. FOR
SUNDAY, THE SHORTWAVE WILL PUSH EASTWARD INTO CENTRAL TEXAS ON
TEXAS AS THE PARENT TROUGH PUSHES INTO THE SOUTHERN PLAINS WITH
BREEZY CONDITIONS MAINLY EAST OF THE RIO GRANDE ON SUNDAY AS AN
UPPER RIDGE BUILDS INTO THE BORDERLAND. FOR MONDAY, THE UPPER
RIDGE WILL SLIDE EASTWARD AS YET ANOTHER PACIFIC STORM SYSTEM
MAKES LANDFALL ALONG THE US WEST COAST MONDAY WITH SOUTH TO
SOUTHWEST FLOW AGAIN STRENGTHENING OVER THE BORDERLAND WITH BREEZY
CONDITIONS AND SOME AREAS OF BLOWING DUST ON MONDAY AFTERNOON.
AVIATION
(18Z TAFS)
ISSUED AT 1125 AM MDT TUE MAR 11 2025
WINDS WILL SHIFT TO THE WEST TO SOUTHWEST IN THE NEXT HOUR OR TWO
AND BEGIN INCREASING WELL AHEAD OF AN UPPER LEVEL DISTURBANCE
CURRENTLY OFF THE SOUTHERN CALIFORNIA COAST. PEAK WIND GUSTS OF 25
TO 30 KNOTS COULD LOFT SOME PATCHY DUST, MOST LIKELY AT DMN AND
LRU.
SCATTERED LOWLAND SHOWERS WILL MOSTLY DIMINISH AS THEY PUSH EAST
OF THE CONTINENTAL DIVIDE TONIGHT. BREEZY WSW WINDS ARE EXPECTED
TO RETURN ON WEDNESDAY AFTERNOON.
FIRE WEATHER
ISSUED AT 144 AM MDT TUE MAR 11 2025
CRITICAL FIRE WEATHER CONDITIONS WILL PERSIST ACROSS THE AREA
TODAY. THE COMBINATION OF GUSTY WINDS AND LOW HUMIDITY VALUES WILL
LEAD TO DANGEROUS FIRE CONDITIONS ACROSS A GOOD PORTION OF THE
BORDERLAND. A RED FLAG WARNING IS EFFECT TODAY FROM NOON TO 8PM
ACROSS MUCH OF THE LOWLANDS WEST OF THE RIO GRANDE AND UP TO THE
SACRAMENTO MOUNTAINS. MIN RH VALUES WILL BE IN THE SINGLE DIGITS
THROUGH MOST OF THE AREA WITH LOWER TEEN VALUES IN THE MOUNTAIN
AREAS. MIN RH VALUES FOR WEDNESDAY MODESTLY REBOUNDING INTO THE
LOWER 20S IN THE LOWLANDS AND LOWER 30S IN THE MOUNTAINS. FOR
THURSDAY, MIN RH VALUES WILL BE IN THE TEENS WITH HIGHER VALUES IN
THE MOUNTAINS, BUT WINDY TO VERY WINDY CONDITIONS WILL LEAD TO
ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS.
