Update on Monday storm

ATLANTIC PROVINCES STORM MOVG INTO ATLC EARLY IN PD AND NEXT SYSTEM DEPENING OFF CAPE COD.. MDL HAD A GOOD HANDLE ON THAT FIRST SYSTEM AND IS EXPECTED TO CONTINUE AS SHOWN BY LATEST 06H QPF VERIF VLD 18Z. COLD AIR INVADING THE GULF OF ST LAWRENCE LIKELY TO GIVE SNOWSQUALLS OVR PRONED AREAS. WRF-NAM IS AN OUTLIER WITH NEXT SYSTEM DEVELOPING OFF ERN SEABORD BEING TOO SLOW. POSITION WISE GEM REG, GLB AND ECMWF ARE IN GOOD AGREEMENT WITH LOW S OF CAPE COD BY 48H. UKMET IS A BIT FARTHER EAST. GEM REG IS THE MOST INTENSE WITH THAT SYSTEM WITH LOW AT 1001MB BY 48H. GLB AT 1005 MB AND GFS NAM AND ECMWF AT 1008 MB ARE WEAKER. THERE ARE POTENTIAL FOR DEVELOPMENT WITH NEGATIVELY TILTED UPR TROF AND CAA BUT GEM REG COULD BE IN THE DEEP SIDE WRT INTENSITY. DIONYSOS SHOWING A LOT OF LATENTE HEAT RELEASE BY END OF PD WITH THAT SYSTEM AND GEM REG COULB BE A CARRY AWAY WITH DEVELOPMENT. WILL GO MORE WITH CONSENSUS AROUND 1005-1008 MB ATM. POSITIONWISE THO GEM REG LOOKS REASONABLE. STAY TUNED FOR TONIGHT FCST.
