ABUNDANT MID AND UPPER LEVEL MOISTURE ASSOCIATED WITH TROPICAL STORM LIDIA WILL COMBINE WITH RICH LOW LEVEL GULF MOISTURE AND A STRONG UPPER LEVEL STORM MOVING OUT OF THE SOUTHERN ROCKIES TO PRODUCE SOME HEAVY RAINS OVER EASTERN OKLAHOMA THROUGH TUESDAY MORNING. A STRONG COLD FRONT WILL MOVE INTO NORTHEAST OKLAHOMA LATE TONIGHT AND INTO SOUTHEAST OKLAHOMA TUESDAY AND BRING MUCH COOLER AIR INTO THE AREA.
