    Nice to get back into the summer afternoon shires.

    Interesting in that the storms that come through BR on Friday went from NW to SE.

    The showers that came through on Saturday went from SE to NW.

      That storm over Baker/Zachary might be causing some road flooding issues.  It hasn’t really moved in the last couple of hours.

      MESOSCALE PRECIPITATION DISCUSSION 0182
      NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
      158 PM EDT TUE MAY 22 2018
      
      AREAS AFFECTED...ALABAMA...WRN GEORGIA...FLORIDA PANHANDLE
      
      CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE
      
      VALID 221757Z - 222300Z
      
      SUMMARY...SHOWERS AND THUNDERSTORMS WILL MOVE SLOWLY IN THE
      VICINITY OF A WEAK LOW IN CENTRAL ALABAMA...AND MAY PRODUCE
      LOCALLY HEAVY RAINFALL AND FLASH FLOODING. RAIN RATES COULD
      APPROACH 2 IN/HR.
      
      DISCUSSION...ALTHOUGH THE SURFACE WIND FIELD AND PRESSURE PATTERN
      ACROSS THE SOUTHEAST IS VERY WEAK...A BROAD CIRCULATION AND
      RELATIVE MINIMUM IN PRESSURE APPEARED TO BE CENTERED NEAR
      BIRMINGHAM. ANALYSIS OF THE LOW-LEVEL CLOUD BANDS WOULD ALSO PLACE
      A CIRCULATION CENTER NEAR BHM...AND THUS IT IS LIKELY THAT A WEAK
      LOW IS SITUATED OVER CENTRAL ALABAMA. SCATTERED CONVECTION HAD
      DEVELOPED AS OF 1730Z AND WAS BECOMING MORE
      NUMEROUS...PARTICULARLY TO THE SOUTH OF THE LOW WHERE LESS MORNING
      CLOUD COVER HAD LIKELY CONTRIBUTED TO GREATER INSTABILITY.
      ALTHOUGH THE CONVECTION WAS GENERALLY CELLULAR AND SCATTERED...A
      COUPLE MESOSCALE BOUNDARIES MAY BE PROVIDING A BIT MORE
      ORGANIZATION. THE FIRST WOULD BE THE SEA BREEZE...AND
      THUNDERSTORMS WERE MORE NUMEROUS IN THE FLORIDA PANHANDLE ALONG
      THIS BOUNDARY. THESE STORMS WERE SLOWLY LIFTING INLAND (TO THE
      NORTH) AND MAY EVENTUALLY MAKE PROGRESS INTO SOUTHERN ALABAMA AND
      SOUTHWEST GEORGIA. THERE ALSO APPEARED TO BE A WEAK SURFACE TROUGH
      OR CONFLUENCE ZONE ARCING TO THE SOUTHWEST OF THE LOW NEAR THE
      I-65 CORRIDOR. A MORE DEVELOPED BAND OF CLOUDS WAS SITUATED IN
      THIS AREA AND SURFACE PRESSURES WERE SLIGHTLY LOWER THAN
      SURROUNDING OBSERVATIONS.
      
      AS THE LOW MOVES SLOWLY NORTH AND EAST...THE TROUGH TO ITS
      SOUTHWEST MAY BEGIN TO PUSH INTO SOUTHEAST ALABAMA AND CONVERGE
      WITH THE SEA BREEZE (OR THE COMPOSITE OUTFLOW BOUNDARY FROM
      ASSOCIATED CONVECTION). THIS COULD PROVIDE A TEMPORARY 1-3 HR
      FOCUS FOR GREATER CONVECTION IN SOUTHEAST ALABAMA AND SURROUNDING
      AREAS. PARTS OF SOUTHEAST ALABAMA HAVE ALREADY EXPERIENCED HEAVY
      RAINFALL IN THE PAST 24 HOURS...WITH RADAR ESTIMATES OF OVER 2
      INCHES. THIS WOULD BE A POTENTIALLY FAVORED AREA FOR FLASH
      FLOODING.
      
      OVER MUCH OF THE OUTLINED AREA NEAR THE WEAK LOW IN CENTRAL
      ALABAMA...THE LOW-MID LEVEL FLOW IS ALSO VERY WEAK AND RAP
      ANALYSIS PLACES THE 850-300MB WIND SPEEDS LESS THAN 10 KNOTS. THIS
      SHOULD ALLOW CONVECTION TO DRIFT SLOWLY. MANY AREA SHOULD CONTINUE
      TO SEE A SCATTERING OF CONVECTION...WHICH WOULD NOT TEND TO FAVOR
      FLASH FLOODING GIVEN THE LIMITED DURATION OF ASSOCIATED RAINFALL
      AT ANY SPECIFIC LOCATION. HOWEVER...BROADLY CONFLUENT FLOW AROUND
      THE LOW AND THE POSSIBILITY OF COLLIDING MESOSCALE BOUNDARIES MAY
      PROMOTE SOME CELL MERGERS AND SUFFICIENT FOCUS TO PRODUCE A FEW
      INCHES OF RAIN IN AN HOUR OR TWO. THIS COULD PRODUCE FLASH
      FLOODING... ESPECIALLY IF IT WAS ALIGNED WITH AREAS THAT HAVE SEEN
      HEAVY RAINFALL IN RECENT DAYS.
