Regional Impacts
Today: Embedded convection with the influential coastal troughing across NS – specifically the South Shore. Only hazards forecast are potentially high rainfall rates and lightning.
Tonight: Offshore deep convection continues, but slowly pulling away.
Wednesday: Pop-up shower risk in extreme western Labrador and northern NB. A few of these could be TCUs tall enough to create a few lightning flashes.
Convective Discussion
Pwats remain high this morning and early this afternoon across parts of NS, particularly the SW. Organized convection could bring locally very heavy rainfall. YQI sounding this AM is basically wet adiabatic from 900mb to the stratosphere. Caribou is much drier above 600mb as it is out of the tropical airmass. The depth of moisture is being closely monitored today and alerts will be issued if a storm back-builds or stalls over a particular region. The special weather statement continues to highlight the potential. The tropical dynamics pull off land this evening, but remain over the marine district tonight. Tomorrow is much quieter with minimal cape to work with, and a return to seasonal temperatures and humidity.
