NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jul 8, 2:55 PM EST, 24 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Grand Rapids MI 355 PM EDT Mon Jul 8 2024 .KEY MESSAGES... - Thunderstorms this Evening, with isolated hail/wind threat - High confidence in heavy rain, medium confidence in location for late Tuesday night into Wednesday - Warmer with a chance of weekend showers && .DISCUSSION... Issued at 355 PM EDT Mon Jul 8 2024 - Thunderstorms this Evening, with isolated hail/wind threat Surface trough combined with late afternoon/early evening max in diurnal instability is resulting in some updrafts current going up across the southwest forecast area and conditions seem favorable for this activity to spread east into this evening with some potential for isolated cores capable of producing downbursts and hail. The storms should diminish with decreasing sfc-based instability later this evening. - High confidence in heavy rain, medium confidence in location for late Tuesday night into Wednesday The slug of tropical moisture associated with the remnants of Beryl will be making its presence felt in at least the southern half of Lower Michigan by late Tuesday night and continuing into Wednesday afternoon. We are concerned with the potential for high rainfall rates as baroclinic processes associated with a tropical cyclone transitioning to extratropical have been known to result in extreme rain rates/amounts. The good news here is that the storm will not be slow moving. Even so, a wide swath of 2 to 3 inches of rain with locally 4 to 5 inches is squarely in the forecast envelope of QPF amounts. See the Hydro section of this discussion for details on possible impacts. Forecast uncertainty on where the northern edge of the heavy rain axis continues to be high, and it is possible the I-96 corridor gets into the 2 inch plus amounts. The higher confidence for those amounts remains further south, along the I-94 corridor. - Warmer with a chance of weekend showers The modified tropical low will be east of the cwa by Wednesday night. High pressure will begin to build in to the region at the surface, but an upper trough will remain overhead. Thus we'll likely see some diurnal cu as lapse rates will steepen with the cooler air aloft. Isolated showers will be possible too both Thursday afternoon and Friday afternoon. However, a stronger short wave is progd to rotate through the trough over the weekend and that will boost our rainfall chances to 40-50 percent. A cold front may try to make a run at Lower Michigan next Monday which would also enhance our chances for storms. It's going to feel steamy again as the temperatures will slowly climb from around 80 Thursday to near 90 by Monday. Concurrently, dewpoints will rise through the 60s to around 70 and so humidity levels will feel very high. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 129 PM EDT Mon Jul 8 2024 Showers have developed along a diurnal heating gradient from near LAN to southwest of AZO. We'll keep a VCSH comment in the TAFs for this. VFR expected through the period. However at MKG/AZO some shallow fog is possible near sunrise due to recent rainfall. && .MARINE... Issued at 355 PM EDT Mon Jul 8 2024 Winds and waves are expected to remain relatively light through Tuesday then offshore winds could pick up on Tuesday night and Wednesday as low pressure, the former Hurricane Beryl, move through. A blend of the NBM and NAM12 was used which keeps winds below SCA, but this will have to be looked at for trends in wind the next couple days. && .HYDROLOGY... Issued at 355 PM EDT Mon Jul 8 2024 The remnants of the hurricane are "Berylling" towards southern Lower Michigan and the current forecast brings a swath of 2 to 3 inches of rain across part of the St. Joe, Kalamazoo and Grand river basins by Wednesday afternoon. Coordination with the NCRFC on the effects of the current QPF amounts for flood potential considering antecedent conditions, which are close to normal for this time of year, suggests that minor river flooding is likely, but major flooding is unlikely. We will continue to look at contingencies should there be significant changes in future QPF. Local flooding of tributary creeks and streams and urban/poor drainage areas seems likely as well, and we may issue an areal flood watch once the details in the location of the heavy rain is better determined. && .GRR WATCHES/WARNINGS/ADVISORIES...
