THROUGH MID NEXT WEEK...
MUCH OF THE PREVIOUS FORECAST STILL APPLIES, AS WE ARE STILL UNDER A
TYPICAL SUMMER PATTERN. THE MAIN THING WILL BE A STEADY INCREASE IN
HEAT AS TEMPERATURES RISE TO THE MID 90S BEGINNING THIS WEEKEND.
TEMPERATURES MAY EVEN CRACK THE UPPER 90S TO NEAR 100 BY MID NEXT
WEEK AS WNW LOW LEVEL TRAJECTORIES PROMOTE DEEPER MIXING. RESULTING
HEAT INDICES WILL BE IN THE 105-110 RANGE, THOUGH SPOTS OF 110+
CANNOT BE RULED OUT. WILL CONTINUE TO CARRY A LIMITED/ELEVATED HEAT
MESSAGING FOR THIS WEEKEND INTO NEXT WEEK. THERE IS POTENTIAL FOR A
TARGETED UPGRADE TO SIGNIFICANT IF TRENDS HOLD. THAT SAID, MOISTURE
REMAINS SUFFICIENT TO SUPPORT THE PERSISTENCE OF DIURNALLY DRIVEN
THUNDERSTORMS. THE MAIN QUESTION IS THE TIMING OF THOSE STORMS, AS
AN EARLIER ONSET COULD LIMIT HEAT RISK A BIT. NOTABLY, LOWER POPS IN
THE WEST INCREASES CONFIDENCE FOR HEAT IN THESE AREAS. GIVEN THE HOT
AND HUMID CONDITIONS, WILL HAVE TO MONITOR FOR MICROBURST POTENTIAL
