DISCUSSION
KEY MESSAGE 1...ABOVE NORMAL TEMPERATURES ARE EXPECTED THROUGH
THIS WEEKEND WITH SHOWER CHANCES RETURNING LATER WEDNESDAY INTO
THURSDAY.
KEY MESSAGE 1 DESCRIPTION...
A BROAD UPPER LEVEL RIDGE IS EXPECTED TO REMAIN IN PLACE ACROSS
THE HUDSON BAY INTO EASTERN CANADA AND THE NORTHEAST US THIS
WEEK, LEADING TO PERSISTENT ABOVE NORMAL TEMPERATURES WITH
DAYTIME HIGHS GENERALLY IN THE UPPER 70S TO WELL INTO THE 80S
THROUGH THIS WEEKEND. DEW POINTS WILL GENERALLY REMAIN
COMFORTABLE IN THE 50S, LESSENING HEAT RELATED IMPACTS. HEAT
RISK IS GENERALLY IN THE MINOR CATEGORY, SUGGESTING ANY HEAT
RELATED ISSUES WILL BE MOSTLY CONFINED TO VULNERABLE
POPULATIONS. THE WARMEST DAY CLOSER TO THE DOWNEAST COAST WILL
BE TODAY BEFORE WINDS BECOME LIGHTER AND OUT OF THE SOUTH WITH
THE DAILY SEA BREEZE ON WEDNESDAY AND BEYOND.
A WEAK DISTURBANCE CUTTING UNDERNEATH THE RIDGE NEAR THE US-
CANADA BORDER WILL PROVIDE MOISTURE FOR CLOUD COVER AND SHOWERS
LATE WEDNESDAY INTO EARLY THURSDAY. THE GREATEST CHANCES WILL BE
ACROSS WESTERN AREAS, WHERE A RUMBLE OF THUNDER IS POSSIBLE BUT
CONFIDENCE IS LOW. THE COMBINATION OF POOR MID LEVEL LAPSE
RATES AND MINIMAL INSTABILITY WITH MLCAPES LESS THAN 500 J/KG
WILL PRECLUDE MUCH OF A THUNDER RISK IN THE CWA. A FEW MORE
CHANCES OF THUNDERSTORMS LATE WEEK INTO NEXT WEEKEND.
