***Pleasantly cool over the Upper Midwest and Great Lakes***
***Scattered showers and thunderstorms for New England***
***Stormy weather for the Central Plains and parts of the Rockies***
With the large scale upper level trough over the Eastern United States,
typical summer-time heat and humidity is much less than usual.
This is forecast to continue through the next two days, and this especially holds true for the Great Lakes region and into the Upper Midwest where a big upper level low resides. The quality air mass will also spread into the Ohio Valley and Mid-Atlantic region for the start of the work week, with mostly sunny skies, mild temperatures, and lower humidity.
Farther east along the immediate East Coast, a slow moving cold front will allow for the development of more showers and storms for the coastal areas of the Southeast, and also eastern New England for Sunday night and Monday morning.
Elsewhere, numerous showers and storms are likely over parts of Kansas, Oklahoma, and Nebraska as a result of a stationary frontal boundary in that region along with shortwave energy aloft. This will also be the area with the best chance of severe thunderstorms and heavy rainfall.
Over the Central and Southern Rockies, diurnally driven thunderstorms can be expected with moisture from the monsoon.
And for the Pacific Northwest, a cold front moving southward will bring drier and cooler conditions for the beginning of the work week.
