DISCUSSION
THROUGH THURSDAY
HEAT REMAINS THE PRIMARY FORECAST CONCERN AS HIGH PRESSURE CONTINUES
TO DOMINATE THE SOUTHWESTERN UNITED STATES. DAILY HIGH TEMPERATURE
RECORDS WERE BROKEN AT SIX OUT OF THE SEVEN CLIMATE SITES IN THE
FORECAST AREA YESTERDAY. HIGH TEMPERATURES WILL REMAIN 15 TO 20
DEGREES ABOVE NORMAL THROUGH SUNDAY AND NUMEROUS DAILY MAXIMUM AND
WARM MINIMUM TEMPERATURE RECORDS REMAIN IN JEOPARDY AREAWIDE. SEE
THE CLIMATE SECTION BELOW FOR MORE DETAILS. WEAK DISTURBANCES RIDE
ALONG THE RIDGING PATTERN THIS WEEKEND, BRINGING A MODEST INCREASE
IN SOUTHWESTERLY WINDS. GUSTS PEAK BETWEEN 15 AND 25 MPH EACH
AFTERNOON.
A PATTERN SHIFT OCCURS NEXT WEEK AS A TROUGH MOVES INTO THE PACIFIC
COAST AND THE RIDGE SUBSIDES. MODELS ARE COMING INTO BETTER
AGREEMENT OF TEMPERATURES RETURNING TO SEASONAL NORMALS BY THE
MIDDLE OF THE WEEK. HIGHS DECREASE 15 TO 20 DEGREES BETWEEN SUNDAY
AND WEDNESDAY, AND FOR LAS VEGAS, THIS MEANS TEMPERATURES RETURNING
TO THE UPPER 70S. SOUTHWESTERLY WINDS WILL ALSO INCREASE ACROSS THE
MOJAVE DESERT AS THE TROUGH MOVES INLAND, WITH A 50 PERCENT OR
GREATER PROBABILITY OF WINDS REACHING 40 MPH EACH DAY MONDAY THROUGH
THURSDAY. LASTLY, THE TROUGH WILL ADVECT MOISTURE INTO THE REGION,
BUT THERE REMAINS WIDE DISCREPANCY BETWEEN MODELS IN MOISTURE
AMOUNTS. EVEN IF THE GREATER MOISTURE SCENARIO PLAYS OUT, MOST OF
THE MOISTURE SHOULD REMAIN TO THE SOUTH OF THE AREA IN CENTRAL AND
SOUTHERN ARIZONA. THIS IS AN IMPORTANT FACTOR IN HOW MUCH
PRECIPITATION WILL MATERIALIZE, IF ANY. CONTINUE TO MONITOR UPCOMING
FORECASTS FOR UPDATES.
