It says a mix of wintry precipitation is expected, followed by rain and mild temperatures.
“Most of Newfoundland can expect a mixed bag of precipitation tonight and Saturday as a warm front crosses the island.”
Snow and ice pellets will develop in the southwest this evening and spread northeastward through the night. Snowfall amounts are expected to range from a trace to 5 cm, except in the north where 5 to 10 cm are expected.
The precipitation will transition through freezing rain to rain overnight in the south and west, and Saturday morning elsewhere. Environment Canada says the potential exists for a three-to-six-hour period of freezing rain, but this could vary within each forecast region as temperatures hover around 0 C before rising rapidly behind the warm front. Along the south coast, heavy rain is expected and rainfall warnings have been issued, with 20 to 45 mm expected. The highest rainfall amounts are expected along the coast, with lesser amounts inland although the freezing rain may persist longer inland.
Environment Canada says with the rain and mild temperatures forecast for Saturday, significant snowmelt can be expected right across the island. Localized flooding in low-lying areas is possible.
High winds are also expected with this system, 70 to 100 km/h in most areas and up to 120 km/h in the Wreckhouse area on the province’s west coast, beginning tonight and continuing until near dawn Saturday.
The weather office cautions motorists to be prepared to adjust their driving with changing road conditions and high winds.
