A relentless heat wave continues to bake Burbank and the rest of the Southland. A hot air mass is hovering over the region. An excessive heat warning went into effect this morning through late evening for portions of the valleys and mountains in So Cal. Yesterday the high hit 100 again in B-town and we can expected it to be just as hot today. At 11 a.m., the temperature was already 90! So the heat is very much on in the Media City.
