Not often do NWS offices like IWX mention Winter in their AFDs during the summer.
 

.LONG TERM...(Sunday Night through Saturday)
Issued at 324 PM EDT Sat Aug 5 2023

The forecast 500-mb chart for Monday looks out of place for early
August; rather fall or winter-like. The crawling MCV turned surface
low is finally absorbed by a stronger trough digging in over the
Illinois Sunday night. As a result, a sprawling upper-level low is
overhead on Monday offering the chance for passing showers and cool
conditions; highs in the mid-70s.

Broad troughing aloft will keep temperatures a touch below normal
through the week. A couple of disturbances bring the chance for
showers and thunderstorms late Wednesday and again near Friday
night. Early indications suggest we may be between systems next
weekend, thus perhaps leaning toward a dry forecast.

The upcoming week looks to be a wash.

That was entertaining. Usually getting tail end Charlie with a line of thunderstorms means Blustery conditions. Stayed calm here but boy did it rain. My tippy bucket is saying 1.46" with 1.40" of that happening in about 30 minutes. Was raining hard but straight down. Stood outside under an umbrella and watched the storm drains get backed up just from the volume of water coming down the street and the bank parking lot. The streets are semi-dry again but there for awhile the land-sharks were making wakes going to the grocery store.

Models sucked ass with this system.  Just 0.15" here.  Nice amount of rain in July so we don't need it that badly anyway at least.

Got nothing today. Ended up with the first completely dry weekend since the middle of June.

Feels like autumn today. Spitting rain showers spinning in from the southeast and temperatures in the upper 60s. I love it.

Tomorrow looks to be our turn. Expecting to suck being stuck in the low to mid-70s the entire day tomorrow.

The high yesterday was 65 at midnight. It stayed between 61 and 64 all day during daylight hours with a thick cloud deck pretty much at ground level, along with drizzle and showers.  Rained 0.6”.

Yes, they did.  It tracked pretty far south and it was not the widespread heavy rain event that was expected.  It did not help that there was no heat/instability in Iowa Sunday.

I actually finished with a solid 0.72", better than most spots around here.  It was a slow soak, too, so probably better than a quick 1+" from a thunderstorm.

Yeah the models definitely struggles with this system.  Once it became 2 distinct waves instead of 1 bigger one the models seemed to be playing a lot of catch up to reality.  Funny thing is the NAM the past 2 days seemed to perform the best for MBY.  :lmao:

 

I did okay with nearly an 1".    Like you say hawkeye it was a slow soak which is great for soil! :thumbsup:
