DISCUSSION
THROUGH THURSDAY
WELL ABOVE NORMAL TEMPERATURES CONTINUE ACROSS THE REGION TODAY.
BASED ON THIS MORNING'S 12Z SOUNDING AT LAS, THE ATMOSPHERE HAS
COOLED SLIGHTLY COMPARED TO YESTERDAY. THUS, EXPECT HIGH
TEMPERATURES TODAY TO BE A FEW DEGREES LOWER THAN THE PAST FEW DAYS.
EVEN WITH THIS "COOL DOWN", TEMPERATURES WILL STILL BE 15-20 DEGREES
ABOVE NORMAL AND EVERY CLIMATE SITE HAS THE POTENTIAL TO BREAK
RECORD HIGH TEMPERATURES. THE PATTERN REMAIN IN PLACE THROUGH THE
WEEKEND WITH HIGH TEMPERATURES REMAINING NEARLY THE SAME AS TODAY
EACH DAY. SEE THE CLIMATE SECTION FOR MORE DETAILS ON RECORDS AS
TEMPERATURES REMAIN WELL ABOVE NORMAL. OTHERWISE, EXPECT DRY
CONDITIONS WITH HIGH LEVEL CLOUDS STREAMING IN AT TIMES THROUGH THE
WEEKEND. BREEZY SOUTHWEST WINDS WILL DEVELOP SATURDAY AND SUNDAY
AFTERNOONS AS A WEAK DISTURBANCE MOVES THROUGH THE MEAN FLOW, EXPECT
GUSTS 15-25 MPH EACH DAY BUT IMPACTFUL WINDS ARE NOT LIKELY THIS
WEEKEND AT THIS TIME.
WE START TO SEE A PATTERN CHANGE NEXT WEEK AS A WEST COAST TROUGH
KNOCKS DOWN THE "HEAT DOME" RIDGE THAT HAS BEEN OVERHEAD FOR THE
PAST FEW WEEKS. CLUSTERS ALL SHOW THIS GENERAL IDEA OF TROUGHING
REPLACING RIDGING, HOWEVER THEY VARY ON TIMING AND STRENGTH OF THIS
TROUGH. DESPITE THE DIFFERENCE, HIGH CONFIDENCE THAT A COOLING TREND
WILL OCCUR THROUGH NEXT WEEK. ABOVE NORMAL TEMPERATURES ON MONDAY
WILL TRANSITION TO NEAR NORMAL BY WEDNESDAY OR THURSDAY, WHICH MAY
FEEL MUCH COOLER AS THIS WILL BE ABOUT 20 DEGREES COOLER THAN TODAY'S
TEMPERATURES. IN ADDITION TO COOLER, WINDS WILL INCREASE IN RESPONSE
TO THE INCOMING SYSTEM. PROBABILITIES OVER 50% FOR WIND GUSTS OVER
40 MPH EXIST AT TIMES EACH DAY NEXT WEEK, BUT WITH UNCERTAINTY IN
THE OVERALL SYNOPTIC SET UP IT'S HARD TO PIN POINT EXACT IMPACTS AND
TIMING. FINALLY, WE WILL ALSO SEE A MOISTURE INCREASE AHEAD OF THIS
SYSTEM. GFS AND ECMWF HAVE VERY DIFFERENT IDEAS OF HOW AN IVT PLUME
WILL SET UP AHEAD OF THE TROUGH, WHICH WILL PLAY A SIGNIFICANT ROLE
IN WHERE/IF PRECIPITATION WILL DEVELOP MIDDLE TO LATE NEXT WEEK-
STAY TUNED!
