WINNIPEG – WEATHER – As Winnipeggers stir to start their day on March 13, 2024, they find themselves enveloped in a dense fog that has prompted an advisory from local weather authorities.

The current conditions, observed at Winnipeg Richardson International Airport at 5:43 AM CDT, highlight a freezing fog with temperatures at -3.3°C and visibility drastically reduced to just 0.6 km.

Here’s an in-depth look at the weather scenario unfolding in Winnipeg and the precautions to take.

Today’s Weather Overview

Current Conditions

With the temperature just below freezing and humidity at a full 100%, the conditions are ripe for the freezing fog that blankets the city. The east-northeast wind is gentle at 6 km/h, but the wind chill factor brings a perceived cold of -6. The atmospheric pressure stands at 101.5 kPa, indicating a rising trend that may bring changes as the day unfolds. The fog, coupled with the risk of freezing drizzle this morning, poses significant challenges for early commuters.

Fog Advisory

The fog advisory in effect underscores the potential hazards associated with near-zero visibility. Residents are advised to exercise extreme caution if travel is necessary, especially during the morning hours when visibility is most compromised. Slowing down, maintaining a safe distance from other vehicles, and being prepared for sudden stops are critical measures under these conditions.

Expected Conditions

As the day progresses, the fog patches are expected to dissipate, giving way to mainly cloudy skies with a slight risk of freezing drizzle in the morning. The temperature is set to climb to a more comfortable high of 3°C, although the morning wind chill will linger at -6. The UV index remains low at 2.

Tonight, the clouds persist, and there’s a 30% chance of light snow overnight, with fog patches likely redeveloping. The low temperature will hover around -2°C, with similar wind chill values to the daytime.

Tomorrow’s Forecast

Thursday promises more cloud cover, with a 30% chance of light snow in the morning and fog patches clearing as the day warms slightly to a high of 2°C. The wind will pick up, coming from the north at 20 km/h, contributing to a cooler wind chill of -7 in the morning. The skies are expected to clear by nighttime, setting the stage for a colder low of -7°C.

Looking ahead to Friday, the forecast indicates increasing cloudiness with a high of 5°C, followed by cloudy periods and windy conditions overnight, with temperatures dipping to -2°C.

Wardrobe Recommendations

Given the fluctuating visibility and temperatures, Winnipeggers should dress in layers to adapt to the changing conditions. Warm, reflective clothing is advisable for those who must travel in the fog, enhancing visibility to others. Additionally, a waterproof layer could be beneficial against the freezing drizzle and light snow.

Weather Trivia

The phenomenon of freezing fog, which occurs when the water droplets in fog freeze upon contact with surfaces in subzero temperatures, is not uncommon in Winnipeg’s climate. It creates a picturesque but hazardous landscape, especially when coupled with the city’s fluctuating March weather.
