Suchan Says: June Heatwave Ahead

Wednesday will be the transition day into the first heatwave of the season which officially arrives Thursday.  It’s important to note the definition of a heatwave is rather loose.  For this particular heatwave, two main factors award it the label.

  1.  Early to mid June average temperatures are well below forecast values.  This same stretch of weather in late July would not qualify as a heatwave.
  2.  The first true hot stretch typically is a bit more difficult to adjust to for the body compared to later in the season.

Forecast highs ahead compared to average

There will not be much rain over the next 3 to 4 days either.  20% or less essentially will cover the period.  The chance of showers or thunderstorms will increase early next week as the next cold front approaches and moves through the area.  While this front brings much needed rain by this point in the forecast, it only offers a small break in the heat.  The air behind it does not have true Canadian origins.  So only slightly cooler with the front then heating back up in the 8 – 14 day forecast.

Not much of a cool down behind this cold front. Still, should be able to keep highs well below 90 for a day or two
