Convective Discussion:
MLCAPE near 500 J/Kg over central and northern NB is anticipated but no real triggering mechanism exists beyond daytime insolation. The shear is very low so if thunderstorms do develop they will be pulse type and very slow moving. Pwat values near 25 mm exist with this airmass. Dry mid layers would allow wind gusts to 60-70 km/h. For tonight and Wednesday embedded thunderstorms are expected associated with a low approaching from the southwest. Pwat values near 45 mm are expected so good downpours are likely with this system. Conditions have been quite dry in many areas of Atlantic Canada this summer so any rain will likely be welcome.
