As you have probably noticed we have milky skies above us off and on over the past few weeks which is caused by fires out west and in Canada. The jetstream has pulled in smoke from British Columbia, central and southern Canada last week which is a tinderbox as it is in the American west. 70% of these fires were caused by lightning – over 700,000 lightning strikes were recorded between June 30 to July 1st in British Columbia.
Seems there are active fires over a large area of Canada and the American NW due to extreme temps and dry conditions in the plains and large forested regions. Temps in Lyton BC have reached 121°F which is hot by Canadian standards (or in the U.S. for that matter). Below is a map of active wildfires in Canada alone (red Dots):
Luckily we have seen our conditions improve over the Great Lakes region over the past few weeks. This week will be comparatively dry with warm temps as it should be in the latter half of July. Today we will see mostly sunny skies with the haze once again overhead from smoke from the mentioned fires. The best rain chances this week will be Tuesday evening and Thursday night.
- Fairly Quiet Pattern This Week Synoptic pattern shows Western CONUS upper high with downstream trough axis across the Northeast prevailing this week. The central Great Lakes are in a northwest flow regime on the western edge of the trough with a series of frontal passages bringing the chance for showers and a few thunderstorms Tuesday evening and Thursday night. Severe weather threat is very low with both of these as moisture and instability is limited. Temperatures will be near seasonal averages through the week. - Stormy Weekend Possible Shortwave trough moving over the western ridging could bring a better chance of thunderstorms Saturday and or Sunday although at that time range ensemble spread makes any details lack confidence. Ingredients appear to be there for some storms with at least potential for heavy rain and maybe low end severe threat.
