AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1030 PM PDT MON APR 27 2026
KEY MESSAGES
* LIGHT SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE TODAY ACROSS THE
SOUTHERN GREAT BASIN WITH BREEZY SOUTHWEST WINDS ELSEWHERE.
* WARMING TREND EXPECTED THROUGH THE WEEK WITH A SLIGHT CHANCE OF
LIGHT SHOWERS WEDNESDAY NIGHT INTO THURSDAY AND AGAIN ON SUNDAY.
DISCUSSION
TODAY THROUGH MONDAY.
THE SOUTHERN GREAT BASIN EXPERIENCED LIGHT-TO-MODERATE RAIN SHOWERS
YESTERDAY AFTERNOON, WITH RAIN GAUGES MEASURING 0.25 TO 0.50 ACROSS
ESMERALDA, SOUTHERN NYE, AND LINCOLN COUNTIES. A FEW EMBEDDED
THUNDERSTORMS ALLOWED FOR OCCASIONALLY HIGHER RAINFALL AMOUNTS. A
SIMILAR STORY CAN BE EXPECTED ACROSS THE SOUTHERN GREAT BASIN THIS
AFTERNOON AS ANOTHER BURST OF ENERGY PUSHES THROUGH THE FORECAST
AREA ALONG THE UPPER-LEVEL FLOW. OTHERWISE, EXPECT BREEZY SOUTHWEST
WINDS ACROSS THE REGION WITH GUST SPEEDS GENERALLY BETWEEN 20 AND 30
MPH.
RIDGING SETS UP OVER THE SOUTHWESTERN CONUS HERE FORWARD, WHICH WILL
ALLOW TEMPERATURES TO CLIMB TO 6-8 DEGREES ABOVE SEASONAL NORMALS BY
THE END OF THE WORK WEEK. WE HAVE BEEN MONITORING THE POTENTIAL FOR
UNSETTLED WEATHER RETURNING TO THE REGION THANKS TO A CLOSED LOW
PRESSURE SYSTEM MOVING INTO BAJA CALIFORNIA WEDNESDAY NIGHT INTO
THURSDAY. ENSEMBLE MEANS SHOW THIS INCOMING WEATHER SYSTEM TRENDING
WEAKER AND FURTHER SOUTH, WITH NOW NEGLIGIBLE CHANCES OF
PRECIPITATION ACROSS THE BULK OF OUR FORECAST AREA. SLIGHT (10-20
PERCENT) POPS PERSIST FOR FAR SOUTHERN MOJAVE COUNTY, BUT WITH PWATS
GENERALLY LESS THAN 0.40", MUCH IN THE WAY OF MEASURABLE
PRECIPITATION IS UNLIKELY. HEADING INTO THE WEEKEND, TEMPERATURES
WILL CONTINUE TO INCREASE UNDER MOSTLY CLEAR SKIES. THE NEXT
POTENTIAL WEATHER SYSTEM TO IMPACT OUR FORECAST AREA WILL DROP DOWN
THE CALIFORNIA COAST LATE-WEEKEND INTO EARLY NEXT WEEK.
AVIATION...FOR HARRY REID...FOR THE 06Z FORECAST PACKAGE
IN THE
WAKE OF AN OUTFLOW BOUNDARY, ELEVATED NORTHWESTERLY WINDS BETWEEN

PERIOD BEFORE BACKING TO THE SOUTHWEST AND DECREASING TO AROUND

DIRECTIONAL PATTERNS THEREAFTER. WIND SPEEDS WILL REMAIN UNDER 8KT
TUESDAY MORNING ONWARD, WITH PASSING BANDS OF MID- LEVEL AND HIGH

FOR THE REST OF SOUTHERN NEVADA, NORTHWEST ARIZONA AND SOUTHEAST
CALIFORNIA...FOR THE 06Z FORECAST PACKAGE...LINGERING OUTFLOW
BOUNDARIES ACROSS MAINLY SOUTHERN NEVADA HAVE RESULTED IN

AREAWIDE SETTLE OUT OF TYPICAL DAILY DIRECTIONAL PATTERNS, WITH
WIND SPEEDS DROPPING TO AROUND 5-10KT. THE EXCEPTION TO THIS WILL
BE ACROSS THE WESTERN MOJAVE DESERT/KDAG, WHERE ELEVATED WESTERLY
WINDS BETWEEN 12-15KT ARE EXPECTED TO CONTINUE THROUGH MID-
MORNING, WITH GUSTY SOUTHWESTERLY WINDS RETURNING DURING THE MID
TO LATE AFTERNOON. ADDITIONALLY, KBIH IN THE NORTHERN OWENS VALLEY
COULD HAVE A PERIOD OF INTERMITTENTLY GUSTY UP-VALLEY WINDS
DURING THE AFTERNOON, BEFORE WINDS SHIFT TO THE NORTH AFTER
