Area Forecast Discussion National Weather Service Grand Rapids MI 959 PM EDT Tue Jun 2 2020 LATEST UPDATE... Update .SYNOPSIS... Issued at 256 PM EDT Tue Jun 2 2020 - Chance of Severe Thunderstorms Late Tonight - Next Chance for Some Showers on Friday - Fair Weather For The Weekend && .UPDATE... Issued at 952 PM EDT Tue Jun 2 2020 Moved up the timing of the arrival of the storms based on trends upstream. Line in eastern WI is pivoting and becoming more perpendicular to the the deep layer flow. From SPC meso page MU CAPE up over 3000 j/kg over Lake MI...couple with Effective Deep Layer Shear up around 45 knots on the backside of the developing bow and stronger DCAPE suggest widespread strong winds as the line moves through along with an increased risk for damaging winds. From about 11 pm to 5 am we should see numerous showers and storms with gusty winds. && .DISCUSSION...(This evening through next Tuesday) Issued at 256 PM EDT Tue Jun 2 2020 - Chance of Severe Thunderstorms Late Tonight - A slow moving cold front will focus convective development across our fcst area mid to late this evening and overnight. Some severe storms are possible due to favorable kinematics for organized convection as deep layer shear will increase to 35-40 kts in conjunction with moderate to potentially strong instability out ahead of the front. Some of the latest CAMs and HREF also show potential for rather strong convection mainly across our central/northern fcst area from around 11 pm through 6 am. There are several mitigating factors to svr wx potential including unfavorable cold frontal timing with decreasing instability during the early morning hours Wednesday. Sfc based convection often diminishes crossing relatively cold Lake MI waters this time of year. On the other hand as alluded to previously a well organized MCS or convection that is or becomes elevated will likely not diminish. A consensus of latest spc sref svr wx parameters suggests decreasing svr wx potential during the early morning hours Wednesday. So all things considered - we expect convection overnight with a chance for some severe storms with damaging wind gusts/hail. The relatively best chance for severe wx will be near to mainly north of KGRR. On Wednesday we expect convective redevelopment to occur south of our fcst area across northern IN/OH. - Next Chance for Some Showers on Friday - A cold front and upper level disturbance will combine to bring some showers Friday. Convection is not anticipated with weak instability forecast. - Fair Weather For The Weekend - A high pressure ridge building in will bring fair and slightly cooler wx this weekend with high temps in the lower to middle 70's. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 803 PM EDT Tue Jun 2 2020 The area of storms developing in Western WI is forecast to track through the region tonight after midnight. Strong wind gusts look likely for KMKG...KGRR and KLAN...but stay tuned in the event the storms track further south. The timing could also change...seems like the storms are developing a little sooner. While a period of MVFR clouds are possible late tonight for the southern TAF sites KAZO to KBTL to KJXN...the storms could alter the location of the impactful clouds. VFR conditions are forecasted to arrive during the day on Wednesday. && .MARINE... Issued at 256 PM EDT Tue Jun 2 2020 Winds will increase a bit tonight but winds/waves will stay below sca criteria. Thunderstorms will pose a hazard to mariners late tonight. Fairly tranquil conditions are forecast on Lake MI tomorrow and Thursday. && .HYDROLOGY... Issued at 256 PM EDT Tue Jun 2 2020 A consensus of latest short range guidance and CAMs suggests rain and convection will develop late this evening and overnight. Some urban and small stream type flooding issues are possible overnight with strongest convection. However the convection will be moving through quickly helping to keep rainfall amounts down. In fact the majority of our area will receive a half an inch of rain or less overnight. Locally higher amounts to an inch or more are possible where heaviest convection moves through as suggested by the 12Z HREF ensemble lpmm. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...None.
