Yesterday’s rain showers were confined to the north of Big Rapids and on the east coast of Wisconsin and around Chicago. Showers could develop along the lake breeze boundary this afternoon however chances are low (20 to 30%. ) Temperatures will once again be in the low 90s.

U.S.A and Global Events for June 1st:
1903: During the early afternoon, one of the most destructive tornadoes in the history of Georgia up to this time, struck the outskirts of Gainesville. The track of the storm was about four miles in length and varied between 100 to 200 feet in width. The tornado touched down about one-mile southwest of Gainesville, striking a large cotton mill at 12:45 pm, Eastern Time, just 10 minutes after 750 employees filed into the great structure from dinner. On the top floor of the mill were employed 250 children, and it was here that the greatest loss of life occurred. Click HERE for more information from the Monthly Weather Review.
1919: Snowfall of almost a half-inch fell at Denver, Colorado. This storm produced their greatest 24-hour snowfall recorded in June. Two temperature records were set: The low temperature of 32 degrees was a record low for the date, and the high of only 40 degrees was a record-low maximum. Cheyenne, Wyoming recorded 1.6 inches of snow, which is one of only six times that at least one inch of snow has fallen at Cheyenne in June.
1934: June started off on a warm note as high temperatures surpassed the century mark across parts of the Midwest. Several locations tied or set record high temperatures for June including Rockford, IL: 106°, Mather, WI: 105°, Hatfield, WI: 103°, Mondovi, WI: 102°, Chicago, IL: 102° and Grand Rapids, MI tied their June record high with 102°.
1999: A tornado with an intermittent damage path destroyed 200 homes, businesses, and other buildings in the southern portion of St. James, Missouri. Of these, 33 homes were destroyed along with the St. James Golf Course clubhouse and two Missouri Department of Transportation buildings. The tornado then moved east, south of the downtown St. James area and intensified. F2 to F3 damage occurred with a 200 to 300-yard damage path. Several homes and farm buildings were severely damaged or destroyed. Further north, severe thunderstorms produced many tornadoes around central Illinois. The most intense tornado touched down in Montgomery County south of Farmersville and moved into southwest Christian County. One person was killed when a semi-trailer overturned at a rest area on I-55. Across eastern parts of the state, high winds up to 70 mph caused damage to trees, power lines, and some buildings. The Mattoon area also reported flooding from these storms, producing $3 million dollars in damage.

.SHORT TERM...(Today through Friday) Issued at 328 AM EDT Thu Jun 1 2023 We are looking at somewhat of a repeat of the weather this afternoon as compared to yesterday afternoon in the form of a few showers and isolated storms mid afternoon-early evening. There will be a small difference in that the hi-res models are in good agreement that there will be development further south along the lake breeze compared to Wednesday. The interesting thing is that there are some moist dew points in place over the western half of the area. Then further east, dew points are dropping off pretty good with the easterly flow bringing the drier air in. Models indicate that up around 1,000 J/kg of ML CAPE is likely along the lake breeze boundary. The better instability is shown to be further south, thus the reason the better chance today of showers/storms south. Severe weather is once again not likely, but can not be ruled out like the stronger storm over Lake County on Wednesday. Some small hail and wind gusts to 40 mph are the most likely given the CAPE, decent mid level lapse rates, and an inverted V sounding giving the gust potential. Deep layer shear staying below 25 knots will keep the storms from becoming too organized, and more of the pulse type variety. The chance of rain then diminishes on Friday, even with warmer sfc temps. The 60F dew points will get pushed out of the area in favor of the 40s and 50s dew points moving overhead. The limited moisture will make it more difficult for the cumulus to grow vertically. .LONG TERM...(Friday night through Wednesday) Issued at 328 AM EDT Thu Jun 1 2023 Michigan will be between a retrograding upper level high situated over the upper mid west and a large upper level low moving southward along the east coast. The interaction between these systems will dominate our weather through the long term. As the large upper level low moves southward along the east coast it will bring several cold fronts through the Great Lakes and the mid Atlantic regions. The first cold front will trek through the area on Saturday. While the warm dry air mass that is entrenched over us will stifle any convection, there will be a slight chance for precipitation and potentially some thunderstorms, especially along the boundary created by the sfc easterly flow and the lake breeze.At the very least that cold front will drop the highs from 10 to 20 degrees above normal to 5 to 10 degrees above normal by Sunday. Another cold front will swing through Monday into Tuesday with the GEFS showing a slightly better chance for precipitation. The caveat to all of this is that the low level northeast flow should keep lower surface dewpoints with dry air dominating the pattern and making any precipitation difficult with the dry pattern expected to continue through next week. The second cold front should drop highs back down to normal and put an end to this heat wave, though high temperatures will still be in the upper 70s to low 80s through mid next week.
