An active night ahead...

Will tonight be a quiet night across the Kawarthas? Not likely. Some active weather is a probability tonight and there is the risk of severe weather. Let's take a look at the latest forecast model run below...





Now I've drawn in the fronts so that this image makes more sense. The first frontal passage will be early this evening as a warm front moves across the region. Rain and some mild (non-severe) activity is possible with this frontal passage but the potential for real active weather will be with the passage of the cold front late this evening. Between 10pm and 12am tonight that cold front looks to push in from the northwest and, after a very warm and humid day, that cold front could trigger some severe weather. Keep in mind that this is only a possibility as no watches or warnings have been issued at the time I write this blog...but there is a very good chance. Cloud heights to the west are in excess of 50 thousand feet which could mean hail and likely very heavy rain. Tornadoes are also possible although I think southwestern Ontario has a better chance of seeing a twister than here in Peterborough...but I'll keep you posted on CHEX and via Twitter if any warnings do pop up. Even though there is just a chance for severe weather it's best to be prepared and cover up the tender vegetation and secure loose patio furniture. Also bring the pets in tonight just in case. I'll have more details for you tonight on Newswatch at 6pm.
