A new HQ for BBQ: Weber moving but staying in Palatine. Weber-Stephen Products, maker of the Weber grill, is moving to new corporate headquarters in Palatine, about 4 miles from its current location, the company announced Wednesday. The new office, on 38 acres on Roselle Road in Palatine, is the former headquarters of Schneider Electric, which moved to Massachusetts last year.
Throughout most of the U.S., the temperature of the ground below the frost line (about 3 to 5 feet below the surface) remains at a nearly constant temperature, generally in the 45 Â° -50 Â° F range in northern latitudes, and in the 50 Â° -70 Â° F range in the south.hroughout most of the U.S., the temperature of the ground below the frost line (about 3 to 5 feet below the surface) remains at a nearly constant temperature, generally in the 45 Â° -50 Â° F range in northern latitudes, and in the 50 Â° -70 Â° F range in the south.
But, a light frost can form with an average air temperature somewhere between 33 and about 37/38. Some surfaces radiate heat better than others, which is why you will get frost at times on elevated surfaces such as car windshields, blades of grass, roofs, or mulch when nothing else is frosty. hard or killing frost is when it gets below 29 or sub-freezing temps are prolonged (more than 24 hours). Plants are much better able to survive a light frost. Once you get below 28 degrees and beyond 6 hours below freezing, plants are much more susceptible to damage.
