Regional Impacts
Slight risk of a thunderstorm this afternoon across central NL.
Slight risk of a afternoon thunderstorm for SE LAB Monday afternoon.
Convective Discussion
An upper trough will cross NL today giving the chance for an isolated thunderstorm. The 12Z tephi out of YJT has a pretty good warm nose at 700 mb, but steep lapse rates below that layer so, if there is ample surface heating, the cap could be breached and an isolated CB could develop this afternoon. There is a fairly strong jet of 30-35 knots in the lower levels so gusty surface winds are possible (even in areas of TCU). PWATs are low so rainfall is not a concern.
There will be a slight chance of an afternoon thunderstorm in SE LAB on Monday in association with a short wave trough.
OTWZ nil sig wx is xpctd.
