KEY MESSAGE 1: HOTTEST TEMPERATURES OF THE YEAR SO FAR FORECAST
EARLY NEXT WEEK
AN ANOMALOUS UPPER RIDGE BUILDING OVER THE EAST-CENTRAL U.S.
WILL DELIVER SUMMERLIKE CONDITIONS OVER THE WEEKEND THROUGH THE
FIRST PART OF NEXT WEEK. MAX TEMPS ARE ON TRACK TO PEAK IN THE
MID 80S TO LOWER 90S MONDAY AND TUESDAY AND COULD CHALLENGE
DAILY RECORDS IN SOME LOCATIONS. MANUAL ADJUSTMENTS WERE MADE
TO LOWER NBM MAXT BY A FEW DEGREES DUE TO A KNOWN SYSTEMATIC
BIAS CORRECTION ISSUE IDENTIFIED DURING THE SHOULDER SEASONS.
THIS SHOULD ALSO KEEP MAX HEAT INDICES UNDER 100F FOR THE MOST
PART. HOWEVER, HEAT RISK IMPACTS WILL CONTINUE TO BE MONITORED
GIVEN THE QUICK RAMP-UP IN HEAT AND LIMITED ACCLIMATION TIME.
A COLD FRONT ACCOMPANIED BY SHOWERS/T-STORMS BRINGS RELIEF NEXT
WEDNESDAY INTO THURSDAY. TEMPERATURES ARE FORECAST TO COOL DOWN
BACK TO HISTORICAL/CLIMO AVERAGES FOR LATE MAY FOR THE END OF
NEXT WEEK.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
VFR CONDITIONS EXPECTED TONIGHT WITH DECREASING CLOUDS AND
WIND. VFR CONTINUES FOR MOST OF SATURDAY WITH SCT SHOWERS OR AN
ISOLATED T-STORM POSSIBLE MAINLY OVER THE WESTERN AIRFIELDS FROM
