Southwestern Saskatchewan is bracing for another blast of messy spring weather, with heavy rain and the possibility of snow prompting a special weather statement across the region. A low-pressure system is expected to move through the southwest, with rainfall beginning Saturday night and continuing into Sunday. Heavy rain is possible at times. Southwest could see significant precipitation totals Environment and Climate Change Canada says precipitation totals could range between 25 and 50 millimetres by Monday morning. “The exact location of the heaviest rain is still uncertain,” Environment Canada said in the special weather statement. Cooler temperatures Sunday afternoon and overnight could also lead to snowfall across parts of the region, although current forecasts suggest any snow would melt on contact. “Should temperatures fall a little more than currently expected, snow may accumulate,” Environment Canada said. “In fact, some model solutions indicate pockets of significant snow are possible.” Related Stories: Frost risk, rain and possible snow on tap for long weekend in southwest Southwest hit with 100 km/h-plus winds and heavy rainfall Power restored to Eastend after 30 hours
