WHILE A NEARLY ZONAL FLOW PATTERN WILL BE THE MAIN INFLUENCE FOR
THE EARLY PART OF THE FORECAST PERIOD. AN MID-LEVEL RIDGE IS
EXPECTED TO MOVE INTO THE REGION THAT WILL RESULT IN MORE EARLY
SUMMER TIME LIKE PATTERN. AS SUCH, THE HIGH TEMPERATURES SHOULD BE
IN THE RANGE OF UPPER 90S TO THE TRIPLE DIGITS. THIS WILL RESULT
IN A MINOR (LEVEL 1 OF 4) TO MODERATE (LEVEL 2 OF 4) HEAT RISK FOR
THE MAJORITY OF THE FORECAST PERIOD. IN ADDITION, THERE IS A
MAJOR (LEVEL 3 OF 4) HEAT RISK FOR MONDAY THROUGH WEDNESDAY. THUS
IT WILL BE IMPORTANT TO PRACTICE HEAT SAFETY NEXT WEEK BY LIMITING
TIME OUTDOORS AND MAKING SURE TO DRINK PLENTY OF WATER TO STAY
HYDRATED.
OUTSIDE OF THE HEAT CONCERNS, SURFACE WINDS SHOULD BE MOSTLY OUT
OF THE SOUTHEAST FOR THE PERIOD WITH GUSTIER WINDS ALONG THE COAST
