DISCUSSION
TODAY THROUGH NEXT WEEKEND.
SEASONABLY WARM CONDITIONS CONTINUE TODAY AS WEAK SURFACE HIGH
PRESSURE REMAINS ACROSS THE REGION ALONG WITH SLIGHTLY ABOVE NORMAL
HEIGHTS. THIS WILL ALLOW TEMPERATURES TO TOP OUT 3 TO 6 DEGREES
ABOVE NORMAL EACH DAY THROUGH MEMORIAL DAY WEEKEND WITH DAILY
AFTERNOON BREEZES. SOME MODEST MID-LEVEL MOISTURE REMAINS ACROSS THE
SOUTHERN GREAT BASIN AND MAY ALLOW FOR SOME VERY LIGHT SHOWER
ACTIVITY TO DEVELOP IN THE AFTERNOON HOURS, ACROSS MAINLY THE SIERRA
AND ESMERALDA COUNTY TODAY AND SUNDAY. DRY CONDITIONS WILL PREVAIL
ELSEWHERE AND ACROSS THE MOJAVE DESERT.
A CHANGE IN THE WEATHER PATTERN IS STILL ANTICIPATED NEXT WEEK AS A
FAIRLY DEEP TROUGH OVER THE PACIFIC NORTHWEST DROPS SOUTHWARD INTO
THE GREAT BASIN ON TUESDAY. THIS LOW WILL THEN MEANDER ACROSS THE
CA/NV REGION WHILE SLOWLY WEAKENING THROUGH THE REMAINDER OF THE
WEEK. THIS PATTERN SHIFT WILL BRING WIDESPREAD GUSTY WINDS TO THE
REGION TUESDAY AND WEDNESDAY, ALONG WITH COOLING TEMPERATURES
MIDWEEK AND BEYOND. THIS LOW WILL ALSO BRING SOME ELEVATED
PRECIPITATION CHANCES TO THE SIERRA AND THE SOUTHERN GREAT BASIN
WEDNESDAY AND THURSDAY, THOUGH ANY PRECIPITATION TOTALS WILL
GENERALLY REMAIN LIGHT. IMPROVING CONDITIONS ARE EXPECTED LATE IN
THE WEEK AND OVER THE WEEKEND AS HEIGHTS RISE AND DRY CONDITIONS
RESUME AREAWIDE.
