DISCUSSION
TODAY THROUGH NEXT WEEKEND.
A WEAK RIDGE OF HIGH PRESSURE WILL REMAIN IN PLACE ACROSS MUCH OF
THE REGION TODAY, KEEPING TEMPERATURES ABOVE NORMAL IN MANY
LOCATIONS. AFTERNOON HIGHS WILL TOP OUT 3 TO 7 DEGREES ABOVE
CLIMATOLOGICAL NORMALS THROUGH MEMORIAL DAY, WITH AFTERNOON BREEZES
DEVELOPING EACH DAY. MODEST MID-LEVEL MOISTURE REMAINS IN PLACE
ACROSS THE SOUTHERN GREAT BASIN, AND THIS, ALONG WITH STRONG
AFTERNOON HEATING, MAY SUPPORT ISOLATED TO SCATTERED HIGH-BASED
SHOWERS AND VIRGA OVER THE SIERRA AND PORTIONS OF INYO, ESMERALDA,
CENTRAL NYE, AND LINCOLN COUNTIES THIS AFTERNOON AND EVENING.
ELSEWHERE, DRY CONDITIONS WILL PERSIST THROUGH TOMORROW.
BY MID-WEEK, A CHANGE IN THE PATTERN IS EXPECTED AS A FAIRLY DEEP
TROUGH OF LOW PRESSURE OVER THE PACIFIC NORTHWEST DROPS SOUTH INTO
THE GREAT BASIN. THE LOW IS THEN EXPECTED TO SLOWLY MOVE ACROSS OUR
AREA DURING THE SECOND HALF OF THE WEEK WHILE GRADUALLY WEAKENING.
AS THIS SYSTEM DROPS SOUTH, GUSTY SOUTH TO WEST WINDS ARE EXPECTED
ACROSS MUCH OF THE AREA TUESDAY AND WEDNESDAY, WITH THE STRONGEST
WINDS LIKELY ACROSS OUR TYPICAL WIND PRONE AREAS OF THE WESTERN
MOJAVE DESERT, SOUTHERN NEVADA, AND CENTRAL AND NORTHERN MOHAVE
COUNTY IN ARIZONA. TEMPERATURES WILL ALSO COOL FROM WEDNESDAY
ONWARD, WITH READINGS FALLING TO A FEW DEGREES BELOW NORMAL IN MANY
AREAS. GIVEN ITS INLAND ORIGINS, MOISTURE WITH THIS SYSTEM WILL
REMAIN LIMITED, WITH ONLY THE SOUTHERN GREAT BASIN SEEING ANY
MEANINGFUL INCREASE IN POPS, AND EVEN THERE RAINFALL AMOUNTS WILL
REMAIN LIGHT. IMPROVING CONDITIONS ARE EXPECTED LATE IN THE WEEK AND
INTO NEXT WEEKEND AS HEIGHTS RISE AND TEMPERATURES RETURN TO NEAR
NORMAL LEVELS.
