Convective Discussion.
There are a couple features worth noting today. First off there is some elevated convection associated with the thickness ridge near the Avalon this morning. This is lying along the 850 thermal ridge and very high PW. Heavy downpours to affect the SE Avalon over the next hour or so. The second feature is a cold front over western NL. Upper level analysis shows a very strong 250 jet (but not in a favorable position). There is plenty of shear (50+ knots), but the instabilities are not that strong. And sat pix shows a lot of cloud cover. If this does burn off allowing some partial clearing there could be a couple decent cells develop this afternoon (across WRN/CNTRL NL) that could give some strong wind gusts. Small hail is also a possibility.
Regional impacts.
Newfoundland: locally heavy downpours across the SE Avalon. SCT cells this afternoon for CNTRL/WRN areas giving some gusty winds.
Nova Scotia, New Brunswick, PEI and Labrador: nil.
