UNGER

PREV DISCUSSION... /ISSUED 242 AM CST FRI MAR 6 2015/

DISCUSSION...SURFACE HIGH IS MOVING INTO MIDDLE TENNESSEE THIS
MORNING WITH PRESSURE GRADIENT WEAKENING AND TEMPERATURES
BOTTOMING OUT DUE TO RADIATIONAL COOLING AND THICK SNOW COVER,
ESPECIALLY IN AREAS TO THE NORTH AND WEST OF NASHVILLE.
TEMPERATURES THIS MORNING AND TOMORROW MORNING WILL BE
SIGNIFICANTLY COLDER IN THESE AREAS, PRODUCING A STRONG THERMAL
GRADIENT ACROSS NW MIDDLE TENNESSEE. LOOK FOR WINDS TO SWITCH
AROUND TO THE SOUTH LATER THIS AFTERNOON AND TONIGHT AS THE
SURFACE RIDGES SHIFTS TO OUR EAST, WHILE AN UPPER RIDGE CONTINUES
TO BUILD TO OUR WEST. SO LOOK FOR TEMPERATURES TO WARM
SIGNIFICANTLY THIS WEEKEND. NEXT ACTIVE WEATHER SYSTEM WILL COME
OUT OF THE GULF SUNDAY NIGHT OR MONDAY, WITH THE DEEPEST MOISTURE
STAYING TO OUR SOUTH AND EAST. THE ECMWF MORE OR LESS STALLS THIS
WAVE OVER THE SOUTHEAST U.S. NEXT WEEK, KEEPING US IN A WET
PATTERN EVEN THROUGH HOUR 240, SO WILL KEEP POP`S IN THROUGH DAY
7. NOT EXPECTING ANY THUNDER EVEN AS TEMPERATURES WARM INTO THE
60`S LATER IN THE WEEK.
