As the Southwest cools off (relatively speaking) from a weeklong string of record-breaking heat, the Northwest will be scorched next.
A strong ridge of high pressure will build over the region the rest of the week, making way for abundant sunshine and suppressed rain chances. High temperatures will be about 15 to 25 degrees above normal, likely reaching record territory for many areas.
The heat will gradually start to build Wednesday through Friday, continuing this weekend and possibly lasting into next week. Highs will soar into the 90s and triple digits from far northern California to Oregon, Washington and Idaho, as well as far northwestern sections of Montana and Nevada. This includes Redding, California; Salem, Pendleton and Portland, Oregon; Seattle and Spokane, Washington; Boise, Coeur d’ Alene and Lewiston, Idaho; Libby and Thompson Falls, Montana; as well as Black Rock Desert, Nevada.
National Weather Service (NWS) forecasters began issuing excessive heat watches Tuesday evening for these areas and may post watches in additional areas over the next day or two.
Some of the hottest weather will be west of the Cascades, eastern Washington and northern Idaho, where highs could exceed 105 degrees this weekend.
Impact on freight
Demand for freight out of the Seattle market (in the Northwest region) has been increasing recently, so drivers may be heading there as the heat wave spreads. This is reflected in the rising value of the Outbound Tender Volume Index (OTVI.SEA) in FreightWaves SONAR (blue line in the chart below). OTVI is a moving index that represents electronically tendered loads offered by shippers to carriers.
The green line is the Outbound Tender Rejection Index (OTRI.SEA) for Seattle, which represents loads that carriers are refusing to accept for various reasons. Rising OTRI values indicate tightening capacity and often mean shippers will end up paying higher rates on the spot market as opposed to lower contract rates.
