..NEW AVIATION
SYNOPSIS
ISSUED AT 213 AM MDT THU APR 25 2024
STRONG WINDS AND BLOWING DUST THIS AFTERNOON AS A PACIFIC MOVES
ACROSS THE SOUTHERN ROCKIES. THE STRONGEST WINDS WILL OCCUR
DURING THE AFTERNOON HOURS ACROSS PORTIONS OF SOUTH CENTRAL NEW
MEXICO. BREEZY TO WINDY CONDITIONS WILL CONTINUE THROUGH SATURDAY
BEFORE QUIET WEATHER RETURNS SUNDAY INTO NEXT WEEK.
DISCUSSION
ISSUED AT 213 AM MDT THU APR 25 2024
WINDY CONDITIONS AREA WIDE TODAY, WITH STRONG AFTERNOON GUSTS,
BLOWING DUST, AND HIGH FIRE DANGER BEING THE MAIN WEATHER HAZARDS.
RAPID INTENSIFICATION OF A 987MB SURFACE LOW IN EASTERN COLORADO
WILL BEGIN LATE THIS MORNING IN RESPONSE TO AN UPPER TROUGH
PROGRESSING OVER THE SOUTHERN ROCKIES. 500 MB JET STREAK AROUND 80
KNOTS WILL CROSS DIRECTLY OVER EL PASO MID-AFTERNOON, WITH DEEP
BOUNDARY LAYER MIXING TO 600 MB. TROUGH AXIS PASSAGE IS TIMED
WELL WITH PEAK MIXING, ESPECIALLY RIGHT UP THE US-54 CORRIDOR FROM
EL PASO UP TO NORTHEAST NEW MEXICO.
MODEL GUIDANCE HAS BEEN CONSISTENT WITH WINDS SPEEDS THE PAST FEW
RUNS AND ENSEMBLE PERFORMANCE OF THE JET STREAK TRACK AND TIMING
HAS BEEN VERY GOOD. WEST-SOUTHWEST WINDS WITH SUSTAINED SPEEDS OF
25 TO 35 MPH WITH PEAK GUSTS AROUND 50 MPH WILL BE MOST COMMON
ACROSS THE NEW MEXICO AND TEXAS LOWLANDS. MOUNTAIN RIDGES AND EAST
SLOPES WILL SEE SLIGHTLY HIGHER GUSTS, PERHAPS 60 MPH. THUS, WIND
ADVISORIES HAVE BEEN ISSUED FOR MUCH OF THE AREA EXCLUDING FAR
WESTERN NEW MEXICO (NEAR THE ARIZONA STATE LINE WHERE WINDS WILL
LIKELY BE WEAKER). HIGH WIND WARNINGS ARE OUT FOR THE SACRAMENTO
MTNS AND SAN ANDRES EAST SLOPE ZONES, INCLUDING CLOUDCROFT,
MAYHILL, AND WSMR. THESE ARE THE LOCATIONS MOST LIKELY TO SEE
GUSTS EXCEED 60 MPH, BETWEEN NOON AND 5PM TODAY.
BLOWING DUST AND EXTREME FIRE DANGER ARE ALSO CONSIDERATIONS FOR
THIS AFTERNOON. EXPECT A RESPONSE FROM DUST SOURCES IN NORTHERN
CHIHUAHUA ROUGHLY AROUND 11 AM TODAY. DUST MODELING SHOWS THE MAIN
PLUMES AFFECTING EL PASO AND HUDSPETH COUNTIES, WITH MORE PATCHY
AND LOCALIZED SOURCES CAUSING REDUCTIONS IN VISIBILITY TO SOUTHERN
NEW MEXICO. VISIBILITY MAY FALL TO 1 TO MILES IN PLACES THIS
AFTERNOON, IMPROVING AGAIN BY THE EVENING HOURS. WINDS WILL
DIMINISH AFTER SUNSET, WITH ONLY LINGERING GUSTS ALONG MOUNTAIN
EAST SLOPES.
FRIDAY LOOKS TO BE A LULL IN THE WINDS AS A JET STREAK EXITS AND
A DUEL-LOW TROUGH SETS UP. CONDITIONS WILL REMAIN BREEZY BUT
LIKELY NOT NEEDING ANY HEADLINES. SECONDARY LOBE WITHIN THE
PREVAILING TROUGH PATTERN ACROSS THE WESTERN US WILL REACH US ON
SATURDAY, LEADING TO MORE WINDY CONDITIONS AND POSSIBLE BLOWING
DUST DURING THE DAYTIME HOURS. WINDS EXPECTED TO FINALLY SETTLE
DOWN SUNDAY INTO NEXT WEEK AS THE POLAR JET STREAK SHIFTS
NORTHWARD.
NO MAJOR WEATHER CONCERNS EARLY NEXT WEEK. CONTINUED DRY
CONDITIONS WITH A WARMING TREND ALLOWING HIGHS TO REACH 90 DEGREES
IN EL PASO AGAIN BY NEXT TUESDAY. MODELS SUGGEST THE APPROACH OF
THE DRYLINE AGAIN MIDWEEK, AND LOW-END POPS EXIST ALONG THE
EASTERN FRINGES OF OTERO AND HUDSPETH COUNTIES. RIGHT NOW ANY
STORM CHANCES LOOK TO BE CONFINED TO THE EAST OF EL PASO WITH DRY
WEATHER PREVAILING ALONG THE RIO GRANDE CORRIDOR AND SOUTHWEST
NEW MEXICO AT LEAST INTO EARLY MAY.

TEXAS. ERCS SHOWING DRY AND PRIMED FUEL CONDITIONS ACROSS THE
LOWLANDS, WITH FUEL MOISTURE CLOSER TO NORMAL OVER THE HIGH
TERRAIN. RED FLAG CONDITIONS BEGINNING AROUND THE NOON TIME HOUR
