THE STRENGTH OF AN H5 RIDGE OF HIGH PRESSURE THAT RUNS 592-596
DM THRU MUCH OF THE WEEK PUTS US IN THE E-SAT 30 YR RETURN
INTERVAL FOR SUCH A STRONG, SEASON OPENING PATTERN. THUS THE
WEEKEND HIGHS IN THE LOW-MID 90S WITH DEW POINTS IN THE LOW-MID
70S JUST REALLY LOOK LIKE THERE IS NOT A LOT OF DIURNAL
VARIATION THRU THE COURSE OF THE WEEK. THE ONLY POTENTIAL RELIEF
WILL BE IN THE FORM OF ISOLATED TO SCATTERED SHOWERS OR STORMS
THAT MIGHT DEVELOP DURING THE MAX HEATING HOURS OF THE DAY, BUT
EVEN IF SO, THAT PROVIDES ONLY BRIEF AND TEMPORARY RELIEF. WITH
HEAT INDICES SOUNDLY REACHING TRIPLE DIGITS DAILY, WE EXTENDED
THE ADVISORY TO COVER THE ENTIRETY OF THE WORK WEEK. THIS
PROLONGED NATURE OF EXTREME HEAT WILL ONLY HEIGHTEN THE RISK OF
HEAT- RELATED HEALTH IMPACTS. THERE IS SOME EXTENDED MODEL RANGE
INDICATION THAT A FRONT MIGHT DROP INTO THE PICTURE TO COOL
TEMPERATURES A LITTLE BY AIR MASS OR HIGHER CHANCE OF
CLOUDS/PCPN NEXT WEEKEND, SO WE REFRAINED FROM EXTENDING THE
HEADLINE FURTHER FOR NOW.
