A strong cold front in September will exit Canada earlier this week, making its presence known from the Dakotas to Texas by Wednesday.
This will skyrocket much of the country dramatically as many deal with record breaking triple digit heat on Labor Day weekend.
Nowhere is this temperature roller coaster as pronounced as in Denver, where the city’s high temperature is expected to drop by 60 degrees from 99 to 37 degrees in just 48 hours from Sunday to Tuesday.
Such a front will bring a rare measurable snow to the Rocky Mountains. In fact, the higher elevations of the Rocky Mountains could hold more than eight inches of snow.
This would be one of the earliest first measurable snowfalls in the area, with powder typically not building up until October.
Frost warnings and frost warnings are also possible when temperatures in the Rockies, the plains, the Midwest and even parts of the South are around 40 degrees below normal.
Meanwhile, excessive heat continues to plague the east and west coasts this week, with little delay expected over the next seven days.
Outlook for September
Next week’s pattern reflects what September could bring.
One of the main indicators of the continued heat in the west is the continuation of the weak monsoons this summer, according to the CPC. The heat and arid conditions will only exacerbate the drought in the area.
September often brings a variety of weather conditions, including tropical activities that peak on September 10th.
