DAY 3 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK  
0106 PM CST WED NOV 20 2024  
 
VALID 221200Z - 231200Z  
   
..NO SEVERE THUNDERSTORM AREAS FORECAST
 
 
   
..SUMMARY
 
 
ISOLATED TO SCATTERED THUNDERSTORMS ARE POSSIBLE ALONG THE PACIFIC  
NORTHWEST COAST ON FRIDAY.  
   
..SYNOPSIS
 
 
A LARGE UPPER LOW WILL START TO MOVE OFF THE EAST COAST ON FRIDAY.  
IN ITS WAKE, A DRY/COOL CONTINENTAL AIRMASS WILL OVERSPREAD THE  
EASTERN CONUS WHICH WILL RESULT IN NO THUNDERSTORM THREAT.  
   
..PACIFIC NORTHWEST COAST
 
 
COOLING AIR ALOFT ACROSS THE NORTHEAST PACIFIC, ASSOCIATED WITH THE  
APPROACHING MID-LEVEL TROUGH, WILL LEAD TO ENOUGH INSTABILITY OVER  
THE WATER TO SUPPORT SOME THUNDERSTORM ACTIVITY. SOME OF THESE  
THUNDERSTORMS MAY IMPACT COASTAL AREAS DURING THE DAY ON FRIDAY.  
VERY STRONG SYNOPTIC WINDS ARE LIKELY ALONG THE COAST AS A SUB-990MB  
LOW MOVES NORTH ALONG THE COAST. THUNDERSTORM ACTIVITY COULD ENHANCE  
SOME OF THESE WINDS AND LEAD TO INCREASED WIND DAMAGE THREAT, BUT  
INSTABILITY IS TOO LIMITED FOR A MARGINAL RISK AT THIS TIME.
