What’s in store for trick-or-treaters this year? Should they pack on the layers or can parents give in to begging children that a coat under their costume will ruin the look?
In Collingwood and The Blue Mountains, Halloween plans may be dampened with some showers on Saturday afternoon and evening. Temperatures will remain cool at 7 degrees. It will be advisable for those going door-to-door to wear a jacket to keep warm and dry. Sorry kiddies.

Environment Canada is warning of “significant” rainfall this weekend for most of southern Ontario. In a lot of areas, including the Collingwood and Blue Mountains area, the rain will continue through Sunday afternoon and may be heavy at times.
A low pressure system arriving Saturday from the American Midwest will spread rain across Southern Ontario from west to east through the day. In many areas the rain will continue through Sunday afternoon and may be heavy at times. An isolated thunderstorm may accompany the rain on Saturday over Southwestern Ontario.
This unseasonably strong low pressure is expected to track just south of the Lower Great Lakes into the Northeastern United States by Sunday. This is a track that is quite uncommon during the summer.
Regions from Windsor to the Golden Horseshoe will likely receive copious amounts of rain totalling 30 to 60 millimetres. Rainfall warnings may be required. Lesser amounts, in the 20 to 40 millimetre range, are expected over Central and Eastern Ontario. Areas farther north, to the northeast of Georgian Bay, should receive even less with the rain arriving Saturday night.
Additionally, strong northeasterly winds are expected to develop Saturday with gusts generally in the 50 to 70 km/h range with the strongest winds along the Lower Great Lakes.
Yesterday was the first time since the end of June that the temperature in the region reached a daytime high above 30. The humidity was a key ingredient in the thunderstorm risk across the region, which was in the path of a cold front passing through. That prompted severe thunderstorm watches to be issued all across southern Ontario, but atmospheric conditions prevented the formation of major storms in the southwest. Temperatures have returned to more seasonal values for the remainder of this week.
Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain.
A few thunderstorms are expected to affect portions of the above regions this afternoon and early evening. Some of these thunderstorms will be capable of producing damaging winds, torrential downpours, and large hail. These thunderstorms will be quite isolated. However, any storms that do develop could be severe.
Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Remember, severe thunderstorms can produce tornadoes. Be prepared for severe weather. Take cover immediately, if threatening weather approaches. In Canada, lightning kills up to 10 people every year. Remember, when thunder roars, go indoors.
Emergency Management Ontario recommends that you take cover immediately, if threatening weather approaches. Environment Canada meteorologists will update alerts as required, so stay tuned to your local media or Weatheradio. Email reports of severe weather to [email protected] or tweet with the hashtag #ONStorm.
For more information:
A hot and humid airmass will affect portions of southwestern Ontario and the Golden Horseshoe today. Humidex values near 40 are forecast for this afternoon and high temperatures of 30 degrees Celcius are expected. A cold front will sweep across the regions this evening bringing a return to near seasonal temperature values for the remainder of the week.
While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for
- older adults
- infants and young children
- people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses
- people who work in the heat
- people who exercise in the heat
- people without access to air conditioning and
- homeless people.
Watch for symptoms of heat illness, which include
- dizziness or fainting, nausea or vomiting
- rapid breathing and heartbeat
- extreme thirst and
- decreased urination with unusually dark yellow urine.
If you experience any of these symptoms during extreme heat, immediately move to a cool place and drink liquids. Water is best.
Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.

A heavy snowfall expected tonight.
It may be the first full day of spring, but it’s no surprise that mother nature is still in a wintery mood. A potent disturbance currently over Minnesota is expected to carve a path across Southern Ontario tonight with the centre of low pressure likely to cross the Toronto area after midnight.
A period of heavy snow is expected beginning late this evening near Lake Huron reaching the Blue Mountains and Collingwood area shortly after midnight. The snow is expected to be very heavy at times with snowfall rates of more than 3 centimetres per hour. Although the duration of snow is not expected to be significant, the accumulation of heavy snow will likely exceed 15 centimetres before it tapers off later tonight near Lake Huron and over Eastern Ontario Saturday morning.
Travellers are urged to use caution tonight into Saturday morning due to visibilities of 200 metres or less in heavy snow as well as significant and rapid accumulation on untreated roads.
Wind chills in the minus 30s are expected overnight Sunday and Monday morning. Temperatures are forecast to drop into the minus 20s overnight and early Monday morning. Light to moderate winds will combine with these cold temperatures to give wind chill values into the minus 30s.
Frostbite (damage, sometimes permanent, to skin and body tissue due to freezing) and hypothermia (a life threatening drop in body temperature) will occur if adequate precautions are not taken when outdoors. These can occur within minutes.
If you are looking for a new activity to try this Family Day weekend, February 15-17 consider ice fishing. Ontario residents can fish this weekend without purchasing a licence.
Or for some fun on the trails, the OFSC is offering the “Try Our Trails” permit to encourage more people to get outdoors and enjoy winter by going snowmobiling on OFSC trails. The permit is available without payment for those who pre-register online and is valid from 12:01 a.m. February 15 until 11:59 p.m. February 17.
Reduced visibilities in local blowing today and possibly Tuesday.
A weather system that passed over Southern Ontario last night and this morning resulted in about 10 cm of fluffy snow in most locales.
Strong west to northwest winds in the wake of this system have developed and are thus resulting in localized blowing snow and associated poor visibilities. North south routes in exposed areas will be most susceptible to poor travel conditions.
The winds are expected to abate somewhat tonight, however may remain strong enough for local blowing snow to persist into Tuesday in some areas.
Dangerous blizzard continues today. Extreme wind chills from minus 30 to minus 40 today and tonight.
Very strong westerly winds continue to blast in bitterly cold Arctic air. Frequent intense snow squalls. Local snowfall amounts of 15 to 20 cm are quite likely in some of the snow squalls by tonight. A combination of the dangerous snow squalls with extreme wind chills of minus 35 to minus 40 continue to produce frequent blizzard conditions today. Frequent to widespread very low to nil visibilities with whiteout conditions are expected especially in exposed areas.
The combination of a fresh heavy snowfall from the recent snowstorm with intense snow squalls and bitter wind chills poses a life-threatening risk for anyone outside for any duration, or stranded in vehicles if roads become snow-blocked. Travellers need to ensure they have an adequate car emergency kit and ample fuel if travelling any distance.
Please note that the City of Barrie will remain to the south of the strongest snow squalls through Wednesday. However, blowing snow can still be expected there.
The blizzard conditions will slowly ease somewhat tonight although the snow squalls and blowing snow are likely to continue in many areas.
Wind Chill Warning Continues
Extreme wind chills from minus 30 to minus 40 today and tonight.
Frigid and strong westerly winds are producing widespread dangerous wind chills of minus 30 to minus 40 today and tonight.
Extreme caution is advised for people heading outdoors. Exposed skin may freeze in less than 5 minutes.
Moreover, it is also suggested to help prevent freezing of pipes in buildings, one could turn on the lowest tap in the house and let it run as a pencil-thin stream or fast drip while keeping indoor temperatures a little warmer at night.
Wind chills will improve slowly on Wednesday as temperatures rise slowly and winds finally begin to ease.
