WHAT HAS CHANGED

-Updated Beach Hazards Statement and Key Messages.

KEY MESSAGES

1) Near normal, to slightly above normal level, temperatures with lower humidity Sunday through early next week.

2) Increasing heat and humidity mid to late week with a return of daily shower and thunderstorm chances.

3) A Beach Hazards Statement was issued for Sunday for the dangers of cold water temperatures.

DISCUSSION

KEY MESSAGE 1...Near normal, to slightly above normal level, temperatures with lower humidity Sunday through early next week.

KEY MESSAGE 1 DESCRIPTION... High pressure will build across the region tonight through early next week. Temperatures will be at near normal, to slightly above normal, levels Sunday through early next week. Less humid conditions will also occur Sunday through early next week.

KEY MESSAGE 2...Increasing heat and humidity mid to late week with a return of daily shower and thunderstorm chances.

KEY MESSAGE 2 DESCRIPTION... Return flow starts to set up by later Wednesday into Thursday in response to ridging well offshore and an incoming mid/upper level trough swinging across Quebec. Precipitable Water Values start to increase Thursday ahead of the trough to over 1.5 inches per the Operational GFS, which may support some healthier rainfall totals. While some scattered showers and thunderstorms are possible Thursday, the better chance looks to be Thursday night into Friday night as the trough axis gets closer and better lift and upper support is around to increase the coverage and odds of shower and thunderstorm activity. Based on the latest timing of the Operational Models, things should dry out by next Saturday and grids reflect this.

KEY MESSAGE 3...A Beach Hazards Statement was issued for Sunday for the dangers of cold water temperatures.

KEY MESSAGE 3...With the Holiday Weekend and extra crowds at the coast, the threat of hypothermia due to cold water continues on Sunday. Even though air temperatures will not be as warm as the last few days, the potential will still be there given how cold the water is and the increased crowds. Remember to use a life jacket if on any watercraft!
