12z GEFS model 7.22.2018
Temperature Anomaly Forecast valid through August 7, 2018.
The trend into early August is for temperatures to remain below average throughout the upper Midwest and western Great Lakes (Blue colors on map) The darker blue colors represent a greater departure from normal compared to the lighter blue colors. Should also be noted that will probably have a least a couple of days mixed in through early August that have above normal temperatures, but overall the trend is for cooler than normal temps to linger for the next 2 weeks or so.

Weather Synopsis
Upper level low covered the Ohio Valley and eastern Great Lakes this afternoon with high pressure of 1024mb over Ontario Province. Mostly cloudy skies across the Northland this morning gave way to clearing skies this afternoon. Highs today were in the 70s with upper 60s near Lake Superior.
Clear to partly cloudy skies this evening with partly to mostly cloudy skies overnight — A few showers or thunderstorms could move into western portions of the area late tonight, otherwise dry. Lows tonight in the lower 50s to lower 60s.
Partly to mostly cloudy skies on Monday with highs in the 70s to lower 80s. A warm front and cold front will move through the area Monday but there isn’t a whole lot of forcing with this system, most of that will move into central Canada tonight. Could see a few showers or isolated thunderstorms develop at times in our area on Monday but I don’t think this will be a real big deal. It will be a little on the muggy side on Monday with dew points ahead of the cold front reaching the low to possibly mid 60s.
Tuesday looks like a nice summer day with some sun and highs in the 70s to around 80 degrees.
A better opportunity for some rain showers comes sometime Wednesday and could linger into Thursday as a stronger system moves through the upper Midwest while an upper level low will be located off to our north. Scattered showers and possibly a few thunderstorms are expected in our area Wednesday and perhaps on Thursday too.
