MONDAY: SOGGY WEATHER PERSISTS, TEMPERATURES WILL DIP

Temperatures will slightly drop on Monday by a few degrees and it will be cooler than the abnormal warmth that was experienced on Saturday.

By Tuesday morning, rainfall amounts in southern Ontario will be heaviest in parts of southwestern Ontario, near Lake Erie, where 15-30 mm is forecast. Potentially higher amounts could occur in localized areas due to embedded non-severe thunderstorms.

Many other areas in southern Ontario will see 10-20 mm of rain during the same time period. Lesser amounts in cottage country and near Lake Huron shores are possible.

LOOK AHEAD: SOME PLEASANT WEATHER THIS WEEK, UNCERTAIN THANKSGIVING FORECAST

While the week will begin on a showery note in southern Ontario, conditions will be mostly fair for a period from the middle of the week to the weekend. The above seasonal temperature trend will return with the help of a dominant upper ridge. Temperatures in the high teens or low 20s are expected, lingering through the Thanksgiving weekend.

Forecasters will be closely watching a hybrid system that is expected to develop off the U.S. East Coast mid or late week. The track and timing of this system are highly uncertain, but this could complicate the long weekend forecast with a threat of rain.

Above seasonal temperatures should dominate most of October, however.

"October will include some extended stretches of mild and dry weather, which will be ideal for enjoying the fall foliage -- running later than normal this year after a warm September," says Dr. Doug Gillam, a meteorologist at The Weather Network, in the monthly outlook.
