Tuesday, October 26th 2021, 4:56 am - Rain will linger into Tuesday for southern Ontario as the unsettled trend sticks around for one more day before improving conditions for mid-week.
The final week of October is off to a wet, windy and chilly start in southern Ontario after a bout of heavy rainfall on Monday. The rain prompted special weather statements and rainfall warnings. The unsettled weather continues Tuesday with more precipitation, but the rainfall won't be nearly as heavy, with another system moving in. However, winds will remain quite breezy, with gusts of 40-60 km/h expected across the region. The good news is that there will be a brief break from the rain Wednesday, with fair weather and milder temperatures expected. More on what's left of the rain and wind Tuesday, plus a look at a quick bounce back for the middle of the week, below.

TUESDAY: RAINFALL, GUSTY WINDS LINGER WITH ANOTHER SYSTEM
After a soaker on Monday, Tuesday won't fare much better in southern Ontario. A trough associated with the system will continue to bring rain to eastern sections of the Greater Toronto Area (GTA) and eastern Ontario through Tuesday before subsiding in the late-evening hours.
While most of the heaviest rains will have passed, some moderate amounts are still to come through Tuesday in portions of the province. Between 20-30 mm is expected across the hardest hit areas, with 15-25 mm anticipated for the southwest and into Ottawa and Cornwall in eastern sections, too.
"Wet conditions and reduced visibilities from rain may make travelling difficult," Environment and Climate Change Canada (ECCC) warns.
Conditions will remain quite breezy on Tuesday, as well, with winds picking up in the morning. Gusts will reach 40-60 km/h through the afternoon and diminishing in the evening.
Temperatures will take another plunge Tuesday, dropping down to the single digits for most areas across southern Ontario. Windsor may be the exception, with a forecast high of 11°C.

LOOK AHEAD: SHORT-LIVED IMPROVEMENT BEFORE NEXT SWATH OF RAIN
Southern Ontario will then get a brief break with fair weather and milder temperatures expected on Wednesday. Thursday will also bring a mix of sun and clouds, with pleasant temperatures overall for late October.
The wet conditions will then develop again Friday, with a slow-moving system bringing periods of rain, windy conditions, and milder temperatures through the end of the week. Showers will linger into Saturday, though the day will not be a washout.
Temperatures look to be a few degrees above seasonal for Halloween, but then turning much colder for the start of November. Forecasters are watching for the potential for more widespread flurries and even some bands of lake-effect snow.
