CURRENTLY ANOTHER WARM DAY WITH HIGHS EXPECTED TO CLIMB INTO THE
80'S AND 90'S FOR MOST PEOPLE IN THE VALLEY. A VERY WEAK BOUNDARY IS
PUSHING THORUGH THE REGION, BUT THAT'S MORE OF A TECHNICAL TERM AS
OPPOSED TO A CHANGE IN WEATHER. IT WILL HAVE LITTLE IMPACT ON OUR
SENSIBLE WEATHER, AS WARM TEMPERATURES WILL PERSIST BEHIND IT FOR
THE NEXT FEW DAYS DUE TO A LARGE MID/UPPER RIDGE ACROSS THE REGION.
GUIDANCE HAS COME IN A COUPLE OF DEGREES LOWER ON THE DEW POINTS FOR
THE UPCOMING WEEK. SO AT THIS TIME IT LOOKS LIKE WE'LL REMAIN JUST A
FEW DEGREES BELOW HEAT ADVISORY CRITERIA (105) FOR THE WEEK IF THE
FORECAST VERIFIES. BUT IT FOR SURE WILL BE A VERY HOT AND MUGGY WEEK
WITH HIGHS EXPECTED TO BE IN THE 90 AND 80'S EVERY DAY AND DEW
POINTS RIGHT AROUND THE 70 DEGREE MARK. VERY LITTLE CHANCES OF RAIN
EVEN WITH THESE WARMER TEMPERATURES AS THE RIDGE REMAINS OVERHEAD
AND SQUASHES PRETTY MUCH ANYTHING THAT LOOKS TO TRY AND DEVELOP.
LONGER RANGE MODELS ARE SHOWING A POSSIBLE BREAKDOWN OF THE RIDGE IN
THE WEEKEND OR EARLY NEXT WEEK AS A COUPLE OF SYSTEMS TRY AND MOVE
THROUGH THE UNITED STATES FIGHTING AGAINST THE RIDGE.
