If that verifies, the band remains stationary and wind gusts are frequently over 35 mph a Blizzard Warning may eventually get posted for LaPorte and Berrien Counties. The current Winter Storm Watch wording includes wind gusts over 40 mph.

Not to complain but the 00z NAM takes the lake effect too far east now lolz (10:1 snowfall map attached) Edit: Taken verbatim of course. This run gets me back in the game for lake effect which is nice. Not seriously complaining. Hope it pans out.

If this were a bigger snow I’d consider chasing the snow band into LaPorte County but I’ll just enjoy the radar returns for this one. I’m too far east to be in the best stuff but hopefully the band will wobble overhead for a bit to get an inch or so.

That’s a rough look for mby. 6+ to my east and 8+ one county to my west. I’m off next week and may do some snow chasing...

Latest GFS clown map. Northern Ohio the bullseye again. At least the trend to continue east has stopped. Nice hit for most of the state (and SE MI).

Heaviest axis of snow trending east.

Euro/Canadian vs. GFS/UKMET? Good to see we're already in midseason form.

Woof. I at least had some hopes for lake effect before this run. Congrats North Carolina, I guess.

52 mph gust at South Bend. Lost power at work for a short time. Pretty good way to end the severe season.

First flakes of the season observed courtesy Lake Michigan. Only a day later than last year when the first snow was on Halloween.

Count me as one of those people. Back in my day you set the time once and you were done! I liked being on Central Time in the summer and Eastern Time in the winter. Okay, I'm not really mad...but still slightly annoyed. I've since come to embrace my 9:30 sunsets in the summer.

IWX put out a SWS ahead of the watches and warnings.

Seems like there will be a lot of reports out of Valpo. Personally, some sub severe winds with the gust front. Tried to get a picture of the shelf cloud but it kind of snuck up on me behind the trees. Lots of rain. Not a ton of lightning. Waiting to hear about potential damage in nearby areas.

Nice. Berrien Co MI and LaPorte Co IN lakeshore getting blasted. Nice cell over northern Lake Co IN too.

Everything in Chicagoland has that look to it. Heads up, Hoosier! I’m sure he’s well aware and of that cell coming in. Looks nasty right now.

Sitting here listening to the police scanner. Hearing sporadic reports of trees down around St. Joseph County IN. Nothing widespread. Sounds like singular trees that came down.

Hit 90 and KSBN. Dew of 68. Winds SE at 23 gusting to 36. Nice hot, humid, windy day in Northern Indiana.

If nothing else 90 degrees, humid and windy will make it feel like I’m in Key West for a day.

The wind was really howling as the shelf cloud moved overhead! I hung out in my car in an empty lot away from trees and power lines just in case.

Just had a nice cell move through South Bend about 40 minutes ago. Pretty shelf cloud followed by gusty winds, small hail and torrential rains.

Mesoscale Precipitation Discussion 0190 NWS Weather Prediction Center College Park MD 522 PM EDT Thu May 14 2020 Areas affected...Southern IA...far northern MO Concerning...Heavy rainfall...Flash flooding possible Valid 142120Z - 150200Z SUMMARY...Storms training over areas that received heavy rainfall earlier today could pose a flash flood threat through late this afternoon into early this evening. DISCUSSION...The GOES-16 visible loop showed a line of towering cumulus forming along and just north of a stationary boundary across portions of southern IA. The formation zone lies on the northern edge of the instability gradient, with SBCAPE over 3000 J/KG over northernmost MO into far southern IA. The storms are developing on the northern edge of the better moisture source, and the combination of moisture and instability allowed storms over Atlantic and Guthrie Center counties to produce hourly rainfall rates in excess of 2.25 inches (though the DMX HCA product does indicate the potential for hail contamination) within the last 90 minutes. The 850/300 mb mean wind is generally aligned with the propagation vectors across southern and central IA, which could foster an environment conducive to continued training. However, without a clear source of lift over the boundary, it is not clear just how extensive the convection becomes along and south of the boundary through 15/00z. Both the latest HRRR/parallel HRRR solutions do have a handle on the initial convective placement, but do not necessarily have a handle on the intensity of the rainfall with the storms themselves. Each model shows a general increase in coverage as higher instability is slowly advected along the front into southern IA. The best coverage (based on the simulated radar imagery from the HRRR/parallel HRRR is expected across southwest IA, where an area of 1.00/2.00 inches of rainfall occurred in earlier convection. Storms training over this area could produce an additional 1.00/2.00 inches or train, which pose a flash flood threat through late afternoon and early evening. Since the coverage of storms in the area that received heavy rainfall earlier today is still unclear, flash flooding is considered possible.

Pretty good bounded weak echo region now.

WPC expanded the excessive rainfall moderate risk into southeast Iowa and basically the northern half of IL. Good write-up below. Excessive Rainfall Discussion NWS Weather Prediction Center College Park MD 1223 PM EDT Thu May 14 2020 Day 1 Valid 12Z Thu May 14 2020 - 12Z Fri May 15 2020 ...THERE IS A MODERATE RISK OF EXCESSIVE RAINFALL FROM CHICAGOLAND TO NORTHERN MISSOURI... ...Moderate Risk Area... A northern stream system skirting across the Midwest, with a developing upper level jet streak during convective maximum, 21-06Z, will interact moderate instability along a slow moving frontal zone, to produce a multi-hour heavy rain event this afternoon/evening. Synoptic deep layer forcing becomes maximized along a zone from northern Missouri and southern Iowa toward northern Illinois and southwest lower Michigan. Many model QPFs align here, such as the NAM, NAM Nest, WRF-NMMB, and recent HRRR runs. The WRF-ARW is a bit of an outlier in how much southward propagation it produces, ending up considerably south of the rest... but the WRF-ARW2 perhaps represents a more resonable southward adjustment that may occur as a result of outflow from early-morning convection. Thus, there are still some placement challenges, especially toward Chicago where the lake breeze may also act to inhibit the northward rebound of instability later on today. Northern Illinois is, however, more hydrologically vulnerable - having received 0.50 to 1.50 inches of rain this morning. Parts of the Davenport area also received some local amounts up to two inches. Aside from the early-day event, much of the region has been running below normal on precipitation recently, with fairly dry soils. Thus a second challenge is whether the evening event is likely to produce impacts consistent with the Moderate Risk category. But there do appear to be enough overlapping factors to support Moderate Risk. Inflow of unstable low level air near and atop the effective surface front and other outflow boundaries will increase to 30-40 knots late this afternoon, with deep layer flow becoming quite parallel to the boundaries. We could see a several hour period of training, causing what is otherwise an average combination of PW and CAPE to produce a few spots of higher-end rainfall totals. The NMMB even signals a small 3-inch / 1-hour amount in Illinois, and the NAM Nest signals local 3 to 4 inch in 3 hour totals, indicative of what could occur. This may lead to numerous flash floods and isolated higher-end impacts. Thanks to the WFOs and RFCs for helping shape the updated Moderate Risk contour.

2.5” of cement so far. Absolutely gorgeous January morning. Nice fat flakes coming down.
