.DISCUSSION...

HIGH PRESSURE CURRENTLY CENTERED ACROSS THE CENTRAL PLAINS IS 
PUSHING INTO THE AREA BEHIND THE EXITING STORM SYSTEM FROM LAST 
NIGHT. SURFACE LOW IS NOW LOCATED OVER THE GREAT LAKES WITH A COLD 
FRONT STRETCHING DOWN THE ATLANTIC COASTLINE AND THROUGH NORTH 
CENTRAL FLORIDA. 

A TIGHTENED PRESSURE GRADIENT WILL KEEP WINDS UP OVERNIGHT...BUT NOT 
AS GUSTY AS EARLIER TODAY. ACTIVE PACIFIC MOISTURE STREAM WILL 
CONTINUE TO BRING HIGH CLOUDS TO THE AREA. GIVEN THE AMOUNT OF COLD 
AIR ADVECTING INTO THE AREA...THESE CLOUDS WILL ONLY HAVE A SMALL 
EFFECT ON OVERNIGHT LOWS. BASED ON HOURLY TRENDS AND LATEST GUIDANCE 
WILL INCREASE LOWS A COUPLE DEGREES...MAINLY ACROSS THE NORTH. 
HOWEVER...MID 20S CAN STILL BE EXPECTED IN THE NORTHWEST TO MID 30S 
IN THE SOUTHEAST.
