Temperature controls the Midwest

This year has brought some crazy weather to Wichita, KS so far. Will sub-zero temperatures stall regular trucking operations? It certainly has!

This winter could be one of the coldest yet. It’s taking many people by surprise, because January started out with warmer weather in many parts of the country. Then temperatures suddenly plunged into the single digits and below in much of the Midwest, including sub-zero temps in Chicago and Minneapolis.

The U.S. has been under severe weather during the first quarter, impacting freight movements. The National Weather Service advises people to stay indoors and keep talking at a minimum while outdoors.

Freight industry concerns

When temperatures drop below freezing and winter storms cover highways with large snowfalls, it affects truckload demand in three ways:

Ice and precipitation slow down trucking operations, which has the effect of reducing capacity.
Businesses may have trouble staffing at full levels as employees stay home or struggle to get to work.
Consumers tend to stay home, cutting purchases at stores and restaurants.

The impact on trucking operations can drive rates up, but slow down business and consumer activity. So every winter event has a rate impact that can really fluctuate depending on timing and severity.

Snowball effect on schedules

Extreme cold can put trucking operations at risk. Trucks may not be able to start, or they may not run reliably. Therefore, fuel lines freeze and schedules slip. Cargo can also be damaged by the cold. If freight needs protection from freezing, the shipper may need to change routing instructions. If there are delays, or the truck is stranded on the highway, the cargo could be ruined.

Most freezables, including water-based products, paints and chemicals, are fine as long as the truck is moving and the weather is just a little below freezing. Some commodities cannot be moved at all until temperatures are more moderate.

When temperatures drop into single digits or below, all bets are off. Most LTL (light truck load) operations will not even pick up freezables. Snowball effecting shippers who may be forced to ship products on temperature-controlled trailers that can provide heat. In some cases, insulated equipment and thermal blankets are enough protection on long hauls.

Unless you are trying to find a reefer in Chicago this week, good luck with that! Especially when the thermometer drops to minus-20.

This winter, we are facing the start of a new polar vortex event, as a cold air mass has been forced over much of the central U.S. CNN reports that “75% of the U.S. population will suffer below-freezing temps this week.” That means dangerous driving conditions. If you are driving, or dispatching drivers, into that mess, make sure to keep an emergency kit and plenty of warm clothing in the truck.

Any and all of these factors have the potential to shift winter shipping patterns. Keep one eye on the Weather Channel and the other on DAT Hot Market Maps, to stay ahead of the news.

Above all, keep warm and stay safe.
