Convective Discussion
A cold front is basically stalled over southern NB but will drift across NS tonight. There is a lot of shear (40 to 60 knots and linear) and the cape is 500 J/kg or less. The shear is likely too strong for the cape but for areas near the front today (southern NB) some enhanced activity is possible. PWAT values of 25 mm will give downpours. Guidance is suggesting hail near 1 cm and low freezing levels near 9000 feet. Dry mid levels support the model guidance of wind gusts to 40 kts.
Garden variety pop-up thundershowers are possible on Monday for Nfld/Lab.
