AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
315 AM PDT THU MAR 12 2026
KEY MESSAGES
* A SIGNIFICANT WARMING TREND WILL CONTINUE THROUGH NEXT WEEK WITH
TEMPERATURES AROUND 20 DEGREES HOTTER THAN NORMAL RESULTING IN
MINOR-TO-MODERATE HEATRISK ACROSS THE AREA.
DISCUSSION
THROUGH NEXT THURSDAY.
HEAT REMAINS THE MAIN HAZARD IN THE FORECAST FOR THE NEXT WEEK OR
SO. HIGH PRESSURE BUILDING OVER THE AREA WILL ALLOW FOR TEMPERATURES
TO WARM TO AROUND 10 TO 15 DEGREES ABOVE NORMAL BY THE END OF THE
WEEK. THE WARMING TREND WILL BE BRIEFLY INTERRUPTED OVER THE WEEKEND
AS A TROUGH MOVES THROUGH THE NORTHERN PLAINS, RESULTING IN A SLIGHT
DECREASE IN 500 MB HEIGHTS FROM SATURDAY INTO SUNDAY. RIDGING WILL
QUICKLY REBOUND EARLY NEXT WEEK, SHIFTING DIRECTLY OVERHEAD BY THE
MIDDLE OF THE WEEK. THIS WILL ALLOW FOR TEMPERATURES TO TOP OUT
AROUND 20+ DEGREES HOTTER THAN NORMAL DURING THE SECOND HALF OF THE
WEEK. WHILE TEMPERATURES LIKE THIS ARE NOT UNUSUAL IN THE DESERT
SOUTHWEST IN THE SUMMER MONTHS, THEY ARE HIGHLY UNUSUAL THIS EARLY
IN THE SPRING. THESE ANOMALOUS TEMPERATURES WILL THREATEN RECORDS
AND BRING WIDESPREAD MINOR-TO-MODERATE HEATRISK (LEVELS 1 AND 2 OF
4) TO THE REGION. HEAT SENSITIVE INDIVIDUALS, PEOPLE WHO HAVE NOT
HAD THE CHANCE TO ACCLIMATE TO THE HEAT, AND THOSE WITHOUT ACCESS TO
ADEQUATE COOLING AND HYDRATION WILL BE AT THE GREATEST RISK FOR
ADVERSE HEAT RELATED IMPACTS. PEOPLE TRAVELING TO THE SOUTHWEST FOR
SPRING BREAK OR MAKING OUTDOOR RECREATION PLANS SHOULD MAKE SURE TO
TAKE PROPER PRECAUTIONS TO MITIGATE NEGATIVE HEAT IMPACTS BY WEARING
LIGHTWEIGHT AND LIGHT COLORED CLOTHING, TAKING EXTRA CARE TO REMAIN
HYDRATED, AND WEARING SUNSCREEN.
