Week of 9/27 - nice temps initially, then a likely cool down

[MWmetalhead]

Next chance of widespread rain appears to be Thursday or Friday for much of lower Michigan, although northern lower Michigan could see rainfall as soon as Wednesday. Let's hope any gloomy weather gets the heck out of here before next weekend. A replay of this weekend's sensational weather appears unlikely.

My forecasted high temps for Detroit and for Grand Rapids:

9/27: 75, 72
9/28 75, 74
9/29: 75, 75
9/30: 75, 75
10/1: 80, 70 (high temp for GR occurs early in the day)
10/2: 64, 64
10/3: 64, 64
10/4: 65, 66


GFS model run from 8AM this morning; first number is projected 5PM temp for Detroit and second number is projected 5PM temp for Grand Rapids:

9/27: 75, 76
9/28 75, 77
9/29: 77, 77
9/30: 78, 83 (wow!)
10/1: 80. 65 (cold front clears Grand Rapids and is on top of Metro Detroit)
10/2: 64, 63 (strong wave of low pressure across the Ohio Valley into western PA and most of New York; this model also projects 100 degree heat for southern California including LA and San Diego).
10/3: 62, 64 (with temps only in the low 50s for much of the Carolinas; this solution seems very questionable).
10/4: 61, 65 (record cold or near record cold temps across a good chunk of the southeastern U.S.)

Euro-AIFS (Artificial Intelligence Forecasting System) model run from 2AM this morning; first number is projected 2PM temp for Detroit and second number is projected 2PM temp for Grand Rapids (I was unable to obtain 5PM data from this source):

9/27: 75, 72
9/28 75, 74
9/29: 72, 74
9/30: 73, 69 (cold front is positioned across central or northern IL, IN, and OH)
10/1: 80. 67 (frontal boundary lifts northward the preceding evening, clearing SE Michigan before sliding back through as a cold front late in the day)
10/2: 66, 66 (near normal temps)
10/3: 62, 63 (summer like weather across South Carolina and temps in the 60s for much of North Carolina)
10/4: 64, 67 (big cool down across the mid-Atlantic with 50s to low 60s but deeper portions of the SE stay warm)
