September 2019 Observations and Discussion

[Hawkeye]

Northeast Iowa is cranking, but the central Iowa line along the front is struggling.

[Andie]

Its a heatwave up here, if those temps were to occur.

Actually it felt pretty good today by comparison with the 100* weeks. Humidity not too bad.

Still I’m ready for the 80* days.

[Hawkeye]

It's looking pretty feeble for Cedar Rapids.  There are better cells to the south.  What a disappointment.

[Hawkeye]

Dubuque is getting a nice storm, again.  It has been a nice couple days for them.

[james1976]

Beautiful rainbow looking east from my yard! Front just blew through. Picked up another 0.55" today and now it's clearing off with a nice refreshing NW breeze.

[Hawkeye]

Two straight evenings with training storms over Dubuque, and EastDubzz is missing it.

[james1976]

DMX going with "fall-like" for tomorrow. I love that.

In wake of the cool front this evening temperatures and dewpoints

will fall overnight into tomorrow. As the parent cyclone moves

slowly over the northern Great Lakes region on Friday it will

spread a stratocumulus shield across a fairly large area on the

back side, with the periphery reaching our northeastern counties

and resulting in mostly cloudy skies there at times. Otherwise

Friday will be mostly sunny with comfortable temperatures, but

strong breezes developing for much of the day. This will

primarily be due to the pressure gradient influence of the

departing but deepening cyclone, and also aided by efficient low-

level mixing and weak cold air advection. Speeds and gusts are not

expected to reach advisory criteria, but it will likely be the

breeziest day our area has seen in a while, and our first taste of

a fall-like frontal system. The winds should die off quickly

around sunset Friday evening, however, as the mixing fades out and

a surface high pressure ridge builds in, rapidly deflating the

pressure gradient.

[East Dubzz]

Two straight evenings with training storms over Dubuque, and EastDubzz is missing it.

Having an absolute blast on the honeymoon, but have been checking on the weather from time to time and have to say I’m quite jealous...

 

My parents weather station has picked up 6.50” of rain this week. 2.25” today.

[Bryan1117]

South Dakota was hit hard again last night, this time with flooding. A large area of 4-7" of rain fell in southeast South Dakota. I have relatives and friends in Mitchell(where the Corn Palace is located), and my uncle and a cousin said they had 3 feet of water in their basements.

Here's a link to some drone footage of flooding in the town of Madison, SD

https://www.keloland.com/news/local-news/drone-video-flooding-in-madison/

It has been a very rough last few days and nights in South Dakota for sure. I went up to Sioux Falls on Wednesday morning for work, as I had a meeting with an account there that was unaffected by the three tornadoes on Tuesday night. There was a good amount of tree damage across the whole city, however the 41st Street corridor (near the Western Mall) was very hard hit. I stayed away from the hardest hit areas as I didn't want to get caught up in the traffic congestion and hinder recovery efforts. 

 

Most of the locals seemed pretty shell shocked that the city actually got hit, many of the long-time residents in Sioux Falls had never seen a storm like this, or remembered the last time a tornado hit the city. The positive thing is that there were no deaths or serious injuries. For three tornadoes (two EF-2 ones to boot) to hit a medium sized city like Sioux Falls at 11:30pm and there not be any fatalities is pretty amazing. I am sure the city will recover quickly as South Dakotan's are a very resilient bunch of people. 

 

Last night I stayed in Sioux Falls before heading back to Omaha this afternoon, and thankfully most of the severe thunderstorms stayed west and north of the city overnight last night. However the local news reports this morning from Mitchell, Parkston, and Madison were showing tremendous, if not record flooding going on in these areas. Hopefully everyone up there manages to stay safe. 

[Iowawx]

Disappointed that Cedar Rapids didn't get much from the evening storms, but there was a strong storm that moved through around 4:40pm that had winds around 40mph and heavy rain. 

 

It looks like southeast Minnesota got some really heavy rain today. I just looked at the hydrograph for the Cedar River at Charles City, IA and it is forecast to rise from 2.8 feet to 17.8 feet. That is a rise of 15 feet! 

[Tom]

Got woken up around 3:00am from loud thunder and torrential rains.  The lightning has been electric.  It's been pouring since then in waves from training storms.  Local reports of 1.5" of rain has fallen with more to go.  While I do enjoy storms at night, it's much more enjoyable before you go to bed!

[Stormy]

Didn't have time to post last eve so will now. Last evening's storms here were kind of lackluster even though it looked good on the COD radar and the widest part came across my area. Still had a brief downpour with top wind gust to 41 mph. and some lightning. Much of the rain fell only moderately heavy and ended up with just 0.42" which is good enough. The tree line 1.5 miles south of me wasn't visible for quite awhile so I'm expecting it rained more nearby and I got in somewhat of a hole.That was the only cell that hit here yesterday.

[Tom]

Over the last couple days, N IL has been ground zero for storms and tropical rainfalls.  This is just from last night....

 

[Andie]

Not again.

 

95L is tracking similarly to Dorian. The Bahamas are in its direct path.

They don't need more wind and rain, but here it comes.

Attm its cloudy and a temp of 68F. More severe weather coming today.

Tbh, I enjoy severe weather during the daytime where I can see the action occurring. Its much more enjoyable. Lightning though is a different story. I prefer lightning at night. I guess it gives a betta show.

"The lightning has been electric.." 

 

Borrowing lines from the late great Yogi Berra I see    To quote Curly Joe "noice!" 

[CentralNebWeather]

What a night and day so far.  Looks like we dropped down to either 50 or 51 degrees early this morning.  Right now sitting at 72 degrees with a dew in the upper 40's with about a 5 MPH wind.  This would be considered chamber of commerce weather.  We have a home high school football game this evening and the weather looks amazing.  No stops for water breaks like we had the first 2 Fridays with the high dews.  

[Minny_Weather]

Under a slight risk & severe t-storm watch now. Wind is the primary threat.

Holy Macro...I am actually in the "Slight Risk Zone."

Man, its gross outside. Temp at 81/75 and RF at 87F. Though, excellent ingredients for severe weather, that's for sure.

[Minny_Weather]

I believe the front arrived about 20 minutes ago as that's when the wind drastically picked up. The line of thunderstorms is now knocking on my doorstep

[Minny_Weather]

Warning over my balcony right now. Looks like a tropical storm outside. Probably the most thrilling storm I've had here since I moved.

Tom, where did you get that map from? Is it from a weather website? I really like those detailed precipitation maps.

I borrowed it off of BAMWx's twitter page...they use some neat weather maps if you ever want to consider subscribing to their company site.

After the morning storms yesterday, the CF swept thru amid gusty westerly winds which felt quite nice all day long.  Temps held in the mid/upper 70's while DP's fell throughout the day and by evening there was a "chill" in the air.  A "Stunning Saturday" is on tap for today with abundant sunshine and highs in the upper 70's.  In fact, after tomorrow's rain chances, the next week is going to be Top Notch all the way through as a finger HP will linger across the GL's and northeast allowing for pleasant weather.  My goodness, just checked my grid forecast and highs will be near 80F with sunshine all across the board next week!  #winningforecast

Can't help but think how similar that map is to last winter's snowstorm jack-zone NW of Chicago and Cook Cnty riding the serious cut-off line. Has anything really changed, yet??

End of summer brilliance! Always found this month to present some of the best beach weather in far SWMI. Too bad most peeps had shelved boat-n-beach mode due to school season starting up. I remember a similar week of 80-ish and sunny maybe 2 or 3 yrs back. 

[Hawkeye]

The NWS is talking about heavy rain tonight.  The WPC has a big area of 1" over Iowa.  However, the HRRR and NAM are saying, "What rain?"  They have all the storms in southern WI and northern IL again.

 

Of course, the CAMs are certainly capable of missing storms.  They did not see the robust complex over the Missouri river valley this morning.

[Niko]

Brilliant sunshine outside w much drier conditions. Temp currently at 63F. Some Autumn-like clouds in the far distance making this a "Perfect Fall Day."

[Niko]

Had some severe weather yesterday afternoon. North of my area, were a lot of uprooted trees and possibly a confirmed weak tornado. Here IMBY, just very hvy rainfall.

[Bryan1117]

Nice band of strong thunderstorms developed just to the north of Omaha this morning... once again not a drop of rain in my backyard. And the beat goes on... 

[westMJim]

Yesterday at Grand Rapids the H/L was 79/61. At this time the departure for September 2019 is 0 so GR is now right at the average for September. For today the average H/L is 74/53. The record high is 95 set in 1939 (so yes it still can get hot) the record low is 31 set in 1899. The warmest minimum is 73 set in 1939 and the coldest maximum is 54 set in 1996. Last year the H/L was 83/57

Here in the west side of the state after the cold front went thur yesterday it became windy and the clouds looked just like fall over here. At this time it is sunny and a cool 66 here at my house.

[CentralNebWeather]

Heat and humidity back for the foreseeable future. One day break and now dews are creeping towards 70 again. 90’s through at least Wednesday with overnight lows close to 70. We are in mid September for crying out loud. Average temps should be about 75 for a high and around 50 for a low this time of year. Close to 20 degrees above average.

I feel for you guys out west.  Holy cow, I don't know how you can cope with the duration of the heat and humidity for that long.  We've been lucky to get breaks from the warmth/humidity over the last few weeks.  It would drive me a little crazy to have to deal with that much heat.

[Niko]

Luckily, TS Humberto will be far enough east, which means impact on the Bahamas will be minuscule. Latest models are pulling this thing away. Good news there for the Bahamians as they are still recovering from this past massive CAT5 Hurricane that devastated the area.
