Canadian Cool Blast Brings Autumn To US

Strong Cool Blast To Provide Comfortable Temperatures To Much of US

 

A strong Canadian weather system will sweep through the central and eastern US over the coming days and bring widespread below normal temperatures as well as showers and thunderstorms along the cold front.  This will provide many regions of the US with very comfortable conditions and lead to lower than normal cooling demand.  In fact, there could even be some localized heating demand over the north-central US as overnight lows drop briefly into the upper 40s and 50s the next few morning.  The far southern and western US will remain hot and drive strong cooling demand, but it will not be near strong enough to counter the much cooler than normal conditions that will be occurring over many high population regions of the central and eastern US.  With production proving to be very strong along with comfortable temperatures expected over many regions this week, another much bigger than normal weekly build should be forthcoming with next week’s EIA release.  In fact, it very well could be the largest weekly gain on deficits so far this season.  That of course will follow this week’s report which will also show a much bigger than normal build.   Weather patterns and builds have been bearish and they will remain so for a little while longer.  Hotter US temperatures will surge into the Midwest and Northeast this weekend and into next week, but how long it lasts is suspect.

1) The center circulation associated with the Canadian cool blast sweeping through the US is labelled as “1”. This is where the core of the coldest temperatures will occur as it tracks through the Midwest and drops overnight lows into the 40s with localized heating demand.

 

2) High pressure remains over the southern US with a weak circulation near Texas, which will help enhance afternoon showers and thunderstorms.
3) The northeastern US is still out ahead of the Canadian cold front and will be quite warm until it tracks through.
4) An upper level circulation off the California coast is helping draw monsoon moisture into California and the interior West with increasing coverage of afternoon and evening showers and thunderstorms.

 

5) The Pacific Northwest received some relief from hot temperatures as a weather system tracked through overnight with showers and thunderstorms.

 

 

Temperature anomalies Wednesday will be much cooler than nomal over a majority of the central and eastern US due to an impressive cool Canadian blast sweping through.  The West will remain hot with temperatuers in the mid 90s and 100s.
