After intense winds brought extreme fire conditions to the Great Plains on Monday, dry and gusty conditions are expected to continue at times through Thursday. Offshore winds will increase the fire danger in the Southwest while also creating the potential for record breaking temperatures. Ongoing wildfires in the Plains may be difficult to contain.
A trough moving through the Central and Eastern United States will spur gusty conditions across the Plain and Midwest on Wednesday. Low relatively humidity will accompany these gusts with abundant dry fuels, like dead grass. On Thursday (image below) a new trough moving through the Rockies will help to continue gusty conditions near the border with Canada. At the same time, surface high pressure building in the Mississippi Valley will create a pressure gradient over the Southern Plains to create gusty conditions by the afternoon.
On Monday, a fire erupted just west of Rapid City that continues to threaten the city. Evacuations remain in place for certain neighborhoods.
In Keystone, SD another fire sparked which has prompted evacuations and closures around Mount Rushmore. Firefighters say good progress has been made to contain the blaze which has been determined to be human caused, though the exact cause is still under investigation.
