Flooding Rains & Record Warmth
More Rain & Record Warmth Tonight
***5:50 PM Tuesday Update -- A few showers this evening, but mostly rain-free and very warm! Temperatures will hold steady in the low to mid teens through the evening and overnight. Periods of rain will redevelop overnight and continue into Wednesday morning. Flooding continues to be a serious concern, especially across the northern half of the Golden Horseshoe as the rain will be heaviest across this region and the ground is still mostly frozen. Rainfall totals will reach 40-70+ mm by Wednesday morning.
Turning Colder Wednesday
More temperature records will be set during the pre-dawn hours on Wednesday across the region. The current record at Pearson for February 21st is 12.9°C and that record is in jeopardy with overnight temperatures in the lower teens.
However, a cold front will cross the region early Wednesday morning and colder weather will spread back into the region through the day with temperatures dropping to near freezing by late afternoon. Thursday will be the coldest day of the week, but it won't be truly cold for late February with highs near seasonal (0 °C).
Active Pattern Continues Late Week & Weekend
Two more system will impact the Golden Horseshoe late week and weekend. The first system will bring a period of rain and milder temperatures for Friday afternoon. We should see have a break with dry weather for Saturday but rain will redevelop Saturday night and continue into Sunday morning. We are watching the threat for a brief period of freezing rain for northern parts of the Golden Horseshoe, but rain will once again be the dominant precipitation type.
While we are seeing a spring-like ending to February there is an abundance of Arctic air and wintry weather across western Canada and eventually we expect a return to a more wintry pattern for Southern Ontario. While the exact timing is still uncertain, we expect this transition will be during the first week of March. Winter is not over just yet and March will likely still bring some significant winter weather (as it often does).
