NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at May 31, 7:20 PM EST, 1 hour 20 minutes earlier.
Area Forecast Discussion National Weather Service Grand Rapids MI 820 PM EDT Fri May 31 2019 LATEST UPDATE... Aviation .SYNOPSIS... Issued at 318 PM EDT Fri May 31 2019 -Limited risk of thunderstorms and heavy rain along the U.S. 10 corridor after 8pm Friday -Severe threat limited to gusty winds and a potential for hail -Severe weather possible throughout the day Saturday as multiple bands of storms move through the area -Cold front makes way into the area Sunday bringing substantially cooler and dry air && .DISCUSSION...(This evening through next Friday) Issued at 318 PM EDT Fri May 31 2019 The primary focus is on chances for strong to severe thunderstorms tonight and Saturday. Overall, the threat for any severe weather is quite low tonight, but there is at least a small risk for gusty winds and hail mainly near U.S. 10 after 8pm. The threat for thunderstorms looks to be more of an issue for Saturday, unfortunately, and a few strong to locally severe thunderstorms are possible near and south of I-96. Based on the 12z CAM guidance, we are largely unimpressed with our chances for thunderstorms in general tonight, with the main threat being confined to the U.S. 10 corridor and lakeshore areas north of M-20. Any storms that do form in northeast Wisconsin and northern Lake Michigan may tend to migrate toward the better sfc based instability over east central Wisconsin. But a few storms may manage to impact particularly the western stretches of the U.S. 10 corridor and locations immediately SW of there. Since these storms may be rooted above the stable marine layer they can potentially survive the trip over the lake. Nevertheless we do not expect this to be a significant event tonight. Saturday looks to be more of an issue with thunderstorm coverage and perhaps intensity as well. SPC HREF guidance is indicating 1000-1500 J/kg south of I-96 while raw ECMWF and GEM guidance is suggesting 1500-2500 J/kg possible. Somewhat complicating matters is the threat for morning convection in the 12z-15z timeframe that could delay destabilization. Even so, the cold front is not poised to move through until the evening, so there is still time to destabilize. Bulk shear magnitudes will be borderline or even suboptimal for a severe event, suggesting multicellular storm mode and sufficient precipitation loading/downdrafts will be needed to produce severe wind gusts. CAPE in the hail growth region looks good so there is a risk for some large hail. PWAT values in the 1.2"-1.4" range, while not off the charts, are high enough to warrant a threat for some localized heavy rain in areas that get repeated rounds of storms. HREF 24hr localized probability matched mean precip amounts suggest there may be small pockets of 1"-2" of rain especially south of I-96. Localized ponding of water on roads may occur with these rain amounts. After FROPA Saturday evening, our temperatures will tumble quite a bit. We're looking at highs struggling to get into the low to mid 60s Sunday and Monday. In fact, interior central Lower MI may deal with a late-season frost Monday morning with temperatures dipping into the mid 30s potentially. The next risk for rain holds off until Tuesday night and Wednesday. && .AVIATION...(For the 00Z TAFS through 00Z Saturday evening) Issued at 821 PM EDT Fri May 31 2019 Three main aviation concerns the next 24 hours are, showers this evening (which may contain gusty winds), fog overnight and thunderstorms on Saturday. The showers would impact the TAF sites between 03z and 06z as they drift south through the area. There is the possibility of some gusty winds to in excess of 30 knots if they directly impact a TAF site. Given low confidence have VCSH wording in, but did not include the gusty winds. Low chance for a few storms tonight as well, but left this out of the TAFs. Fog is possible again late tonight as winds will be light and skies try to clear in the wake of the line of showers/storms. MVFR fog would be a good bet, with IFR possible. A couple of rounds of thunderstorms look possible on Saturday. The first one appears to be from mid morning through mid afternoon with another one possible towards evening. Included VCTS wording in the TAFs from midday through mid afternoon. && .MARINE... Issued at 318 PM EDT Fri May 31 2019 Aside from thunderstorm hazards to mariners Saturday, we'll be watching for enhanced wind and wave action for Sunday that should hold below SCA. High pressure moving in along with NW flow could boost waves especially near and south of Muskegon during the day Sunday. && .HYDROLOGY... Issued at 318 PM EDT Fri May 31 2019 The rivers near Vicksburg and Maple Rapids remain above bankfull, with only low lying areas near the river under any water. No significant river flooding is expected over the next several days. There are several rounds of thunderstorms likely to affect our area over the next day or two. These are expected to move through fairly quickly, but if multiple thunderstorms happen to track over the same areas repeatedly, bigger rainfall totals and local ponding of water on roads is possible. Always slow down and drive carefully during heavy rain, especially at night. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...None.
