Next 7 days of rain are still a big item.
Rains his month have been OVER forecast by every model, for everytime frame and by every forecaster...........including me but this time they may be coming:

Total accumulation
believe when see it Mike. Been so dry here we almost got one out of the east last nite. Our local come on this am and says it raining in St Louis and soon will be here. Well one problem Mr Met, as anyone with a radar can tell the rain is heading west out of St Louis and last time I checked Indianapolis is way east of that location....the things you see on TV!
I'm in the wait and see camp. There has been consistent forecasts of rain here in NE Ohio over the last couple days, but I haven't seen it.
I agree with you guys. For the past month, every model, every forecast and forecasters has been MUCH too wet, including me.
We'll see what happens this time.
Severe storm risk the next few days:

Latest 12Z GFS operational model run has no heat ridge, in week 2, other than in the Southwest to the far S.Plains. In fact, its actually on the cool side in the East.
Keep in mind this is just one model run and pretty far out and contradicts most previous guidance(so it is probably wrong).
However, ng did take a small hit when it came out:
gfs_namer_360_200_wnd_ht | gfs_namer_360_500_vort_ht |
gfs_namer_360_1000_500_thick | gfs_namer_360_850_temp_ht |
Most of the rain that falls, is in the next 9 days on this GFS model.

The week 2 forecast guidance is getting interesting.
Note the heat ridge backing up a bit. The Southeast will shift to having a weak trough vs a heat ridge. This is very important.
A heat ridge in the Southeast, pumps in warm humid air into the Midwest and will be causing all the rain in the next week with jet stream and front dynamics interacting with the moisture in the midsection of the country.
However, take away the strength of that moisture pump with its southerly winds blowing deep moisture from the Gulf of Mexico well into the Midwest and replace it with a trough, that has the opposite effect............suppressing moisture/confining it to closer proximaty to the Gulf because winds on the back side of the trough will be towards the south, not from the south...........so air masses will be drier and of more of a continental origin as you get farther north from the GOM.
As a result, the 8-14 day forecast is dialing in some dryness now, with the heat centered a bit farther northwest than it has been:

The experimental week 3 and week 4 weather forecast continues the late week 2 pattern, backing the heat ridge farther west and having a weak upper level trough in the Southeast US:
