DISCUSSION  
 
ISSUED AT 248 PM EST SUN DEC 15 2024  
 
UPPER-LEVEL RIDING REMAINS TO THE WEST AS A WEAK SURFACE HIGH IS IN  
PLACE AT THE SURFACE. THE OVERALL PATTERN ACROSS THE SE IS  
RELATIVELY FLAT, WITH SHORTWAVE ENERGY STAYING WELL TO THE NORTH,  
TRAVERSING THE HIGH PLAINS AND GREAT LAKES REGION. THIS SETUP  
MAINTAINS THE FAVORING OF THE STATUS QUO.  
 
A BREEZY ENE FLOW CONTINUES WITH A STRONGER GRADIENT IN PLACE. WITH  
A WARMER AND MORE HUMID AIRMASS CONTINUING TO ADVECT INTO THE  
REGION, DAYTIME INSTABILITY HAS CONTINUED TO FAVOR AN INCREASE IN  
CLOUDS, ALONG WITH SHOW QUICK-PASSING SPRINKLES AND SHOWERS. WHILE  
THE EXPECTATION IS FOR A POCKET OF DRIER AIR TO MOVE IN TONIGHT, THE  
GENERAL TREND IS FOR MOISTURE TO GRADUALLY INCREASE FOR THE NEXT  
COUPLE DAYS. WHILE A LOT OF GUIDANCE CONTINUES TO SUGGEST THAT THERE  
SHOULDN'T BE MUCH IN THE WAY OF CONVECTION, THE CLIMATOLOGICAL  
SIGNIFICANCE OF THE ABOVE NORMAL TEMPERATURES AND MOISTURE ARE  
HARD TO IGNORE. WHILE IMPACTS REMAIN LIMITED, HAVE INCREASED POPS  
TO AROUND 20% ACROSS THE MUCH OF THE AREA DURING THE AFTERNOON  
ESPECIALLY, WITH MENTION OF SPRINKLES IN THE MORNING AND ALONG THE  
COAST. THE SETUP REMAINS FAVORABLE, AND PERSISTENCE IS A USEFUL  
TOOL IN THIS SETUP.  
 
BY THE MIDDLE OF THE WEEK, THE NEXT FRONTAL BOUNDARY LOOKS TO  
ARRIVE. SCATTERED SHOWERS AND THUNDERSTORMS EVEN ARE FAVORED AS THIS  
FRONT APPROACHES WEDNESDAY AFTERNOON AND EVENING. A COOLER AND  
DRIER AIRMASS IS THEN FAVORED TO SETTLE IN BEHIND THE FRONT.  
ANOTHER SECONDARY FRONT THEN LOOKS TO ARRIVE OVER THE WEEKEND TO  
REINFORCE THE COOLER AND DRIER AIRMASS ON SATURDAY. WHILE COOLER,  
THE OVERALL SETUP LOOKS QUITE NICE LATE WEEK AND INTO THE WEEKEND.  
 
 
   
AVIATION  
 
(18Z TAFS)  
ISSUED AT 1251 PM EST SUN DEC 15 2024  
 
WITH AN ENE FLOW, LOW-LEVEL MOISTURE, AND WEAK SURFACE-BASED  
INSTABILITY, CLOUDS AND SOME LIGHT SHOWERS/SPRINKLES ARE POPPING  
ACROSS THE INTERIOR AND SWFL. THIS SHOULD CONTINUE THROUGH THE  
AFTERNOON WITH MINIMAL IMPACT. HOWEVER, THERE IS AROUND A 10%  
PROBABILITY FOR MVFR CIGS TO OCCUR WITH THESE QUICK PASSING SHOWERS  
IF THEY MOVE OVER A TERMINAL. WEATHER CONDITIONS SHOULD QUIET  
OVERNIGHT AS THE ATMOSPHERE STABILIZES AND SOME DRYING OCCURS.  
HOWEVER, MOISTURE REBOUNDS TOMORROW, SUGGESTING A SIMILAR SETUP  
COULD OCCUR AGAIN, AND LIKELY WILL CONTINUE THROUGH THE MIDDLE OF  
THE WEEK.  
 
 
   
MARINE  
 
ISSUED AT 248 PM EST SUN DEC 15 2024  
 
A BREEZY ENE FLOW REMAINS THROUGH THE MIDDLE OF THE WEEK, KEEPING A  
MODERATE TO CHOPPY SEA STATE WITH HAZARDOUS CONDITIONS FOR SMALL  
CRAFT ESPECIALLY OFFSHORE. BY MID-WEEK, RAIN CHANCES INCREASE OVER  
COASTAL WATERS AS WELL AS THE NEXT COLD FRONT APPROACHES. A BRIEF  
PERIOD OF HIGHER WINDS AND SEAS WILL BE FAVORED AS THE FRONT MOVES  
THROUGH.  
 
 
   
FIRE WEATHER  
 
ISSUED AT 248 PM EST SUN DEC 15 2024  
 
NO MAJOR CONCERNS WITH RH VALUES REMAINING WELL ABOVE CRITICAL  
THRESHOLDS THROUGH THE MIDDLE OF THE WEEK.
