Atlantic: Rounds of rain return ahead of weekend blast of heat

Tuesday, July 23rd 2019, 8:00 pm - Cooler than seasonal temperatures accompany the next round of rain in Atlantic Canada

The break between systems was a short one for Atlantic Canada as rain and possibly a rumble of thunder returned to the region on Tuesday. A muggy, southerly flow continues into late week, bringing several shots of rain to the region, including some from the remnants of Tropical Depression Three. More on this week's rain risk, plus a look at the warming trend on tap, below.

ROUNDS OF RAIN THROUGH WEDNESDAY MORNING

A low pressure system chugging up the Eastern Seaboard is bringing showers, and possibly a rumble of thunder, back to parts of the Maritimes. With the jet stream directing storm traffic just offshore, it's mainly eastern Atlantic Canada that stands to see showers from this system.

"The next pulse of moisture brings a widespread additional 5-15 mm through Wednesday morning," says Weather Network meteorologist Kevin MacKay, adding that 10-20 mm is likely across eastern Newfoundland by the time it tapers on Wednesday as well.

TROPICAL REMNANTS WORK THEIR WAY UP THE COAST

The next round of rain will follow hot on its heels, however, as the remnants of the once Tropical Depression Three work their way up the coast. The impacts from the leftovers of this storm -- which dissipated on Tuesday afternoon -- will be minimal, but eastern Atlantic Canada can expect some additional rainfall from it on Wednesday and Thursday.

COOLER THAN SEASONAL TEMPERATURES THROUGH MID-WEEK

Temperatures will continue to hover around the upper teens and low 20s through the mid-week mark, but with a warming trend set to return as we head into the weekend.

"A warmer summer pattern develops for late weekend and into next week as well, becoming quite humid across the Maritimes," says meteorologist Dr. Doug Gillham.

By Saturday, temperatures will rebound to near 30°C in northern and central New Brunswick and the mid-20s across P.E.I., Newfoundland and southern Nova Scotia.
