DISCUSSION
 
INCREASINGLY MOIST AIR WILL CONTINUE TO SPREAD NORTH OVER  
THE REGION THROUGH WEDNESDAY, AS A COLD FRONT BECOMES NEARLY STATIONARY  
AND WAVES OF LOW PRESSURE MOVE NORTHEAST ALONG THE FRONT. SCATTERED TO  
NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE A CONCERN, WITH  
THE POTENTIAL FOR VERY HEAVY RAIN AND FLOODING PROBLEMS.  
 
THE PRESSURE GRADIENT WILL SUPPORT POOR DISPERSION THIS EVENING THROUGH  
EARLY TUESDAY MORNING. RAIN-INDUCED FOG WILL BE POSSIBLE DUE TO ABUNDANT  
LOW-LEVEL MOISTURE.

AFTER DAYBREAK, AND BECOME SOUTHWEST AT 5 TO 10 MPH BY AFTERNOON.  
TRANSPORT WINDS WILL BECOME SOUTHWEST AND INCREASE TO 10 TO 15 MPH.
