DISCUSSION
ISSUED AT 1233 PM MDT WED APR 16 2025
CLEAR SKIES WITH PATCHY BLOWING DUST HAVE DEVELOPED ACROSS
SOUTHERN AND SOUTHWESTERN NM THIS AFTERNOON. WILL CONTINUE TO
MONITOR FOR THE NEED OF ANY BLOWING DUST ADVISORIES AND/OR DUST
STORM WARNINGS THROUGH THIS EVENING.
THE PATTERN WILL CONTINUE TO BE ACTIVE THROUGH THIS WEEKEND.
SOUTHWEST FLOW ALOFT WILL INCREASE TODAY THROUGH FRIDAY. THIS WILL
BE IN RESPONSE TO AN UPPER LEVEL LOW OFF THE SOUTHERN COAST OF
CALIFORNIA INITIALLY MOVING SLOWLY EAST BEFORE MERGING WITH A FAST
MOVING UPPER LOW FROM THE GREAT BASIN AREA BY THURSDAY NIGHT. THE
MERGED UPPER TROUGH WILL THEN MAKE ITS WAY THROUGH NEW MEXICO
FROM FRIDAY THROUGH SATURDAY. IN RESPONSE TO THE APPROACH OF THIS
SYSTEM, A STRONG SURFACE LOW IS EXPECTED TO DEVELOP IN EASTERN CO
AND WESTERN KS TOMORROW. THE INCREASED SURFACE PRESSURE GRADIENT
COMBINED WITH GOOD MIXING INTO THE MID LEVELS WILL ALLOW FOR WINDS
TO INCREASE INTO THE 25 TO 35 MPH RANGE, WITH GUSTS OVER 50 MPH
FOR THE LOWLAND AREAS, AND AS HIGH AS 30 TO 40 MPH, WITH GUSTS
APPROACHING 65 MPH FOR THE HIGHER TERRAIN AREAS OF THE BLACK/GILA,
AND SAN ANDRES/SACRAMENTO RANGES. THUS, THE WIND ADVISORIES AND
HIGH WIND WARNINGS ALREADY ISSUED FOR TOMORROW WILL REMAIN IN
PLACE. IN ADDITION TO THE WINDS, WE WILL ALSO HAVE WIDESPREAD
BLOWING DUST, SO THE BLOWING DUST ADVISORY WILL BE MAINTAINED AS
WELL. SOME OF THE VISIBILITIES WITH THE DUST COULD BE REDUCED TO
LESS THAN A HALF MILE AT TIMES, SO DUST STORM WARNINGS MAY BE
NEEDED. IN ADDITION TO THE WINDY CONDITIONS, WE WILL SEE A COOLING
TREND IN TEMPERATURES THROUGH THE END OF THE WEEK AS THE UPPER
TROUGH AND LOWER HEIGHTS APPROACH.
ALTHOUGH THERE WON'T BE AS STRONG OF A SURFACE PRESSURE GRADIENT
TO WORK WITH ON FRIDAY, AMPLE MIXING WILL ALLOW FOR ANOTHER WINDY
DAY ACROSS SOUTHERN NEW MEXICO AND FAR WEST TEXAS. SOUTHWEST WINDS
IN THE 25 TO 35 MPH RANGE WITH HIGHER GUSTS ARE EXPECTED,
RESULTING IN ANOTHER ROUND OF BLOWING DUST AS WELL, WITH BLOWING
DUST ADVISORIES POSSIBLY NEEDED FRIDAY AS WELL.
AS THE UPPER TROUGH MAKES ITS WAY THROUGH THE AREA FRIDAY NIGHT
INTO SATURDAY, THERE WILL BE A CHANCE FOR PRECIPITATION, MAINLY
FOR THE NORTHERN HALF OF THE AREA. THERE WILL EVEN BE A CHANCE FOR
SOME MIXED PHASES OF PRECIPITATION IN THE HIGHEST ELEVATIONS
WHERE SOME SLEET AND/OR SNOW COULD MIX IN WITH ANY RAIN THAT DOES
DEVELOP. THE MOST LIKELY TIMEFRAME FOR ANY PRECIPITATION WILL BE
DURING THE DAY SATURDAY. TEMPERATURES WILL ALSO BE SIGNIFICANTLY
COOLER SATURDAY WITH HIGHS RANGING FROM AROUND 40 IN THE HIGHEST
ELEVATIONS TO THE MID/UPPER 70S ALONG THE RIO GRANDE IN TEXAS.
FOLLOWING THE PASSAGE OF THE UPPER LEVEL TROUGH, ZONAL FLOW OR
WEAK RIDGING IS EXPECTED TO DEVELOP ALOFT OVER THE REGION. THIS IS
EXPECTED TO YIELD GENERALLY QUIETER WEATHER, WITH WINDS IN THE 10
TO 20 MPH RANGE, AND A WARMING TREND IN TEMPERATURES. HIGHS BY
THE MIDDLE OF NEXT WEEK SHOULD RANGE FROM THE MID 60S IN THE
HIGHER ELEVATIONS TO UPPER 80S ALONG THE RIO GRANDE IN TEXAS.
