DISCUSSION
THROUGH THE WEEKEND.
LATEST SATELLITE IMAGERY SHOWS A CUTOFF LOW SPINNING OFF THE BAJA
PENINSULA. GUIDANCE HAS THIS LOW DRIFTING ENE TODAY, JUST CLOSE
ENOUGH TO BRING A ~20% CHANCE OF ISOLATED SHOWERS ACROSS
SOUTHEASTERN SAN BERNARDINO AND SOUTHERN MOHAVE COUNTIES, MAINLY
SOUTH OF I-40. CANNOT RULE OUT A RUMBLE OF THUNDER OR TWO (10%
CHANCE). GUSTY OUTFLOW WINDS OF 30-40 MPH ARE POSSIBLE (20%) NEAR
ANY PRECIPITATION ACTIVITY. ELSEWHERE, DRY CONDITIONS PREVAIL.
THE MAIN STORY THROUGHOUT THE FORECAST PERIOD IS THE SIGNIFICANT
WARMING TREND AS RIDGING BUILDS. HIGHS TODAY ARE FORECAST TO RANGE
FROM THE UPPER 60S TO LOW 80S. HOWEVER, BY SUNDAY, WE'RE LOOKING AT
HIGHS IN THE UPPER 70S TO MID 90S. FORECAST VALUES OVER THE WEEKEND
ARE 15-20 DEGREES ABOVE NORMAL, RESULTING IN WIDESPREAD MINOR
HEATRISK (MODERATE IN DEATH VALLEY). LOOKING AT LAS VEGAS
SPECIFICALLY, LATEST GUIDANCE INDICATES A 25-50% CHANCE OF REACHING
90 ON FRIDAY, WHICH WOULD TIE THE EARLIEST OCCURRENCE OF 90 ON
RECORD. CHANCES FOR 90+ JUMP TO OVER 75% ON SATURDAY. LOOKING AHEAD
TO NEXT WEEK, MODELS ARE IN GOOD AGREEMENT THAT HIGH PRESSURE WILL
CONTINUE TO BUILD. IN OTHER WORDS, THE WARMING TREND SHOWS NO SIGN
OF STOPPING THROUGH MID-MARCH. DAILY AND MONTHLY RECORDS ARE LIKELY
TO BE CHALLENGED.
