HEAT, STORM RISK TO CONTINUE SATURDAY

A second system, a cold front, will trek east across the Maritimes Saturday morning, bringing another threat for thunderstorms, mainly for New Brunswick. Again, they are expected to remain non-severe in nature. Showers will reach Newfoundland by Sunday morning.

The heat and humidity will continue to increase and move east Saturday. Temperatures in parts of New Brunswick and Nova Scotia will exceed the 30-degree mark. Humidex values will be in the low- to upper-30s across the Maritimes.

A slight drop in temperatures is expected for Sunday across Atlantic Canada, but things will remain on the hot and humid side in most of New Brunswick and southern areas of Nova Scotia and P.E.I. Humidex values will be in the low 30s for some parts of New Brunswick, P.E.I. and southern Nova Scotia.

COOLER TEMPS, MORE UNSETTLED WEATHER NEXT WEEK?

Looking ahead, there is the potential for a second system to track along the cold front, which will stall south of the region early next week. This will bring the threat for significant rain around Tuesday.

"Cooler weather for the middle and end of next week, but trending warmer for next weekend. Warmer than normal for the following week as we make the transition from July to August," said Weather Network meteorologist Dr. Doug Gillham.
