AS A SECOND LOW PRESSURE SYSTEM WELL SOUTH OF THE REGION MOVES AWAY TO THE EAST WINDS WILL SHIFT TO WESTERLY AND LEAD TO A GENERALLY QUIET PERIOD WITH ISOLATED DAY TIME SHOWERS AND THUNDERSHOWERS. LONG RANGE MODELS ARE HINTING AT ANOTHER COMPLEX INTERACTION BETWEEN A TROUGH MOVING IN FROM THE WEST AND A MORE INTENSE LOW SOUTH OF NOVA SCOTIA NEAR THE END OF THE WEEK. THERE IS CURRENTLY LITTLE CONSENSUS WITH REGARDS TO TIMING AND POTENTIAL AMOUNTS OVER THE BASIN, IF ANY. THE FORECASTER MAY BE CONTACTED AT 1-902-426-4813 OR AT WEATHERASPC(a)EC.GC.CA END/ASPC
