OVERALL, WEATHER CONDITIONS WILL BE TYPICAL OF THOSE EXPECTED IN
EARLY SEPTEMBER THIS WEEK WITH VERY WARM DAYTIME TEMPERATURES AND
MILD OVERNIGHT LOWS ALONG CHANCES FOR LIGHT RAINFALL. THE
ADVERTISED COOL-DOWN FOR LATE IN THE FORECAST PERIOD HAS BEEN
DELAYED EVEN MORE AND NOW LOOKS MORE LIKELY TO HOLD OFF UNTIL NEXT
WEEKEND.
THE FLOW ALOFT SHOULD AMPLIFY QUICKLY AS AN UPPER-LEVEL RIDGE
OVER THE ROCKIES ELONGATES AND DEEP TROUGHING DIGS OVER THE
EASTERN HALF OF THE CONUS. UPPER-LEVEL HEIGHTS IN THE CORE OF THIS
TROUGH WILL BE ABOUT 2-4 STANDARD DEVIATIONS BELOW NORMAL FOR
THIS TIME OF YEAR - KEEPING TEMPS FROM REBOUNDING TO STRONGLY.
EARLIER GUIDANCE FOR BELOW NORMAL TEMPERATURES HAS BACKED OFF WITH
COOLER SURFACE AIR WAITING LARGELY UNTIL NEXT WEEKEND.
THE BROAD TROUGH AXIS OVER THE EASTERN HALF OF THE COUNTRY STILL
MEANS DISTURBANCES COULD BRING SOME CHANCE FOR SHOWERS OR STORMS
TO THE REGION, AND TUESDAY INTO WEDNESDAY CURRENTLY LOOKS TO BE
THE BEST TIME RANGE FOR THAT TO OCCUR WITH A PASSING SHORTWAVE
THROUGH WITHIN THE BROADER LONGWAVE TROUGH. TIMING AND STRENGTH
OF THE WAVE DETAILS COULD ADJUST THIS WINDOW FOR RAINFALL. /NF/EC/
