-- Changed Discussion --
A COLD FRONT WAS PUSHING THROUGH CENTRAL AL/GA AT 18Z. LOCAL RADARS SHOW SHOWERS AND A FEW THUNDERSTORMS DEVELOPING OVER INTERIOR PORTIONS OF THE FLORIDA PANHANDLE AND THE SOUTHWEST CORNER OF GEORGIA. SPC CONTINUES TO HIGHLIGHT A MARGINAL RISK FOR ISOLATED STRONG TO SEVERE STORMS THROUGH THIS EVENING FOR SOUTHWEST GEORGIA, SOUTHEAST ALABAMA AND THE WESTERN PANHANDLE. THE GREATEST THREAT WITH THESE STORMS WILL BE STRONG WIND GUSTS AND HAIL POSSIBLY REACHING SEVERE LIMITS. THE COLD FRONT WILL CONTINUE TO PRESS SOUTHWARD AND INTO OUR CWA OVERNIGHT. MOST CONVECTION SHOULD DIMINISH BY LATE THIS EVENING. WILL KEEP A SLIGHT POP FROM 00Z TO 06Z ALONG AND SOUTH OF A LINE FROM NEAR DOTHAN TO VALDOSTA. LOWS WILL RANGE FROM THE LOWER 50S NORTHERNMOST ZONES TO LOWER 60S ALONG THE COAST. .SHORT TERM [TUESDAY THROUGH WEDNESDAY NIGHT]... ANOTHER SHORTWAVE WILL MOVE THROUGH THE REGION ON TUESDAY, BRINGING SCATTERED THUNDERSTORMS TO THE AREA. MODEL SOUNDINGS INDICATE THE POTENTIAL FOR CAPE OVER 2000 J/KG IN THE AFTERNOON, HOWEVER FORECAST SHEAR VALUES ARE NOT IMPRESSIVE AT THIS TIME. SPC HAS ISSUED A MARGINAL SEVERE THREAT FOR TOMORROW, WITH WIND AND HAIL BEING THE GREATEST CONCERNS. EXPECT HIGH TEMPERATURES TOMORROW IN THE UPPER 70S TO LOW 80S. CLOUD COVER AND SLIGHT RAIN CHANCES OVER MOST INLAND AREAS WILL CARRY OVER INTO WEDNESDAY AS A BACK DOOR COLD FRONT APPROACHES FROM THE NORTHEAST. WEDNESDAY`S TEMPERATURES WILL START OUT IN THE LOW 60S AND ARE EXPECTED TO REACH THE LOW 80S DURING THE AFTERNOON. THE CHANCE OF RAIN WILL DIMINISH AFTER SUNSET. .LONG TERM [THURSDAY THROUGH MONDAY]... AT THE START OF THE PERIOD, SOUTHERLY FLOW ON THE WESTERN EDGE OF THE SUBTROPICAL RIDGE WILL PREVAIL ACROSS THE REGION. BY FRIDAY, A STORM SYSTEM WILL BEGIN TO TAKE SHAPE ACROSS THE MID MISSISSIPPI RIVER VALLEY AS A NORTHERN STREAM SHORTWAVE DROPS OUT OF CANADA. THIS SYSTEM WILL PUSH A COLD FRONT INTO THE SOUTHEAST ON FRIDAY AFTERNOON AND MOVE INTO OUR REGION ON SATURDAY. THE BULK OF THE DYNAMICS SHOULD REMAIN TO THE NORTH OF OUR REGION ON SATURDAY AS THE COLD FRONT MOVES THROUGH, SUGGESTING ONLY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WITH THE FRONT. THEREAFTER, HIGH PRESSURE BUILDING OVER EASTERN NORTH CAROLINA WILL PROVIDE FOR A SLIGHTLY COOLER AND SOMEWHAT DRIER AIRMASS ACROSS THE REGION INTO THE FIRST OF THE WEEK. AS THIS HIGH SHIFTS INTO THE WESTERN ATLANTIC MONDAY AFTERNOON, WARMER AND MORE MOIST CONDITIONS WILL RETURN. TEMPERATURES THROUGHOUT THE LONG TERM PERIOD SHOULD BE ABOVE NORMAL, WITH A BRIEF PERIOD OF NEAR NORMAL TEMPERATURES ON SATURDAY AND SUNDAY BEHIND THE COLD FRONT.
