As we still have an upper flow from the east north east, cool air is still getting into the upper levels over the Central and Northern parts of the province. The combination of the cool air aloft and the spin or vorticity will provide an environment where thunderstorms can develop.
As for any indication of summer like weather in the near future? Not really. In fact I had to go all the way to Tuesday June 4th to see when the next upper level ridge starts to build in.... in the meantime, continue to expect a few showers in the forecast with just limited breaks.
