Comfortable “Fall-like” conditions will continue for Muncie through Friday afternoon with high temperatures in the mid-70’s and sunny, clear skies because of a high pressure building in over the central Plains region. This will be a beautiful stretch of weather to get outside and enjoy the sunshine.
To accompany the surface high pressure, an upper level trough has moved into the Great Lakes and the eastern US that is responsible for delivering the drier weather and cooler temperatures.
Looking toward the weekend a shortwave trough will move through Minnesota and into the Upper Peninsula of Michigan by Friday night. 850mb flow will begin to shift to a southerly flow as the shortwave continues to move towards the East Coast on Saturday increasing warm air and moisture advection into the region. As a result temperatures and dew points will rise throughout the weekend for a quick return to muggy summer conditions!
Friday night has a slight chance of thunderstorms and showers. Saturday and Sunday are expected to warm up quickly as ridging at 500mb builds in from the east. Pop-up thunderstorms (30 % chance) are possible as the exiting shortwave interacts with the unstable environment in place over much of the Ohio River Valley. Saturday and Sunday are expected to return to summer-like conditions with high temperatures in the mid-80’s and dew points returning into the upper-60s and low-70s.
Get out and enjoy the end of your first week back at Ball State!
