KEY MESSAGES

BEFORE A SYSTEM BRINGS ANOTHER SHOT OF GUSTY WINDS AND COOLER
TEMPERATURES BY MID/LATE WEEK.
DISCUSSION
THROUGH FRIDAY.
THE N-S PRESSURE GRADIENT REMAINS FAIRLY STRONG TODAY, ESPECIALLY
LOOKING AT THE DIFFERENCE BETWEEN ELY AND NEEDLES. THIS GRADIENT IS
DRIVING THE GUSTY NORTH WINDS IN THE LOWER COLORADO RIVER VALLEY,
WITH GUSTS REMAINING 20-40 MPH THROUGH THE NIGHTTIME AND MORNING
HOURS. WINDS SHOULD SUBSIDE BY LATE AFTERNOON OR EARLY EVENING,
BRINGING AN END TO ANY IMPACTS. MAIN CONCERNS CONTINUE TO BE
HAZARDOUS BOATING CONDITIONS ON THE LOCAL LAKES.
ONCE THE WINDS SUBSIDE, IT LOOKS LIKE WE ARE IN FOR SEVERAL DAYS OF
WARMING AND MORE SETTLED WEATHER. THE WARMING TREND BEGINS TODAY AND
LASTS THROUGH TUESDAY AS TEMPERATURES REACH ~10 DEGREES ABOVE
NORMAL. BREEZES REMAIN LIGHT AND DRY CONDITIONS LARGELY PREVAIL. THE
ONLY MENTIONABLE POPS (~20%) DURING THIS TIME ARE CONFINED TO
EASTERN MOHAVE COUNTY MONDAY AFTERNOON AS A WEAK DISTURBANCE SNEAKS
UNDER THE RIDGE. CANNOT RULE OUT A THUNDERSTORM OR TWO IN THE AZ
STRIP. BY MID/LATE WEEK, FORECAST CONFIDENCE DECREASES AS WE WAIT
FOR GUIDANCE TO COME INTO BETTER AGREEMENT ON THE INTERACTION OF TWO
SYSTEMS. THE FIRST IS A CUTOFF LOW MEANDERING OVER THE NE PACIFIC
WHILE THE OTHER IS A MODELED SHORTWAVE MOVING SOUTHEAST THROUGH
WESTERN CANADA. THE KEY TO THE EXTENDED FORECAST SEEMS TO BE WHETHER
THESE SYSTEMS CAN PHASE OR NOT. IF THEY ARE ABLE TO PHASE, THE
COMBINED SYSTEM LOOKS TO ARRIVE LATE IN THE WORK WEEK. IF UNABLE,
THE NORTHERN SHORTWAVE MOVES THROUGH THE NORTHERN ROCKIES WHILE THE
CUTOFF LOW SLOWLY DRIFTS TO THE CA COAST BY THE WEEKEND. THE FORMER
SOLUTION WOULD FAVOR STRONGER WINDS AND PROBABLY KEEP THE BULK OF
PRECIPITATION CHANCES CONFINED TO THE HIGH TERRAIN AND SOUTHERN
GREAT BASIN. THE LATTER SHOULD FAVOR LIGHTER WINDS AND BETTER
PRECIPITATION CHANCES AREAWIDE. BOTH SCENARIOS FAVOR A COOLDOWN,
THOUGH TIMING VARIES BASED ON THE ARRIVAL OF THE SYSTEM.
