Convective Outlook Valid for Today and Tomorrow

Thunderstorm Outlook for Day 1

 

Convective Discussion

There is a slight risk of thundershowers this afternoon and evening across SE NB, NRN/ERN NS, Cape Breton and PEI. There not a lot of support, but a fairly potent short wave trough will be moving through later today. An approaching 250 mb jet will place this areas near the left exit region which may support some development. CAPE values will be low, but there will be increasing shear as the day progresses (upwards of 40 knots). Freezing levels are quite low (6-7,000 feet) as well. Expect numerous TCUs to form (15,000-20,000 feet) with ISOL thundershowers as well. Given the low freezing levels, small hail/ice pellets is a possibility in some of the stronger echoes. Also gusty winds can be expected in some TCU/CBs. OTWZ nil sig weather is expected.

 

Regional Impacts

MRTMS: ISOL thundershowers possible this afternoon and evening.
