NWS Detroit, MI wrote its last area forecast discussion before the first event at Jun 25, 6:32 PM EST, 28 minutes earlier.
Area Forecast Discussion National Weather Service Detroit/Pontiac MI 732 PM EDT Sun Jun 25 2023 .AVIATION... Area of showers and thunderstorms in advance of encroaching low pressure will shift to the east and northeast of the terminals early in the forecast. However, additional isolated to scattered activity will persist overnight with increased shower coverage on Monday as this low crosses the area. Will forgo thunder mention Monday as a majority of activity will remain showers. That said, isolated storms will be possible at times. VFR conditions will eventually lower to MVFR as increased moisture works into the area with this system. South to southwest flow will persist into Monday and veer to the west and northwest late in the forecast. For DTW...Area of rain/embedded thunderstorm will wind down and shift east 01z-02z with just isolated showers thereafter into the night. Predominant showers will return Monday along with MVFR cigs. DTW THRESHOLD PROBABILITIES... * Medium for ceilings aob 5kft tonight, high Monday. * Medium for thunder through 01z-02z. && .PREV DISCUSSION... Issued at 307 PM EDT Sun Jun 25 2023 DISCUSSION... Scattered convection has developed to our west this afternoon ahead of a strong mid-level shortwave dropping in from the Midwest. These storms have been able to take advantage of moderate mid-level lapse rates and high near-surface dew points producing a corridor of high MLCAPE to our west. Instability over the local area is ramping up as higher moisture advects in from the south and some cloud clearing aids in diabatic heating. This should be sufficient to sustain a severe threat through the evening hours as the storms continue to congeal into more of a linear mode. No significant changes to forecast rationale from this morning's update. Severe wind gusts to 60-70 mph will be the primary threat with large hail to golf ball size and a few weak tornadoes also possible. Heavy rainfall and frequent lightning will accompany the storms as well. The main threat window will be from 5pm to 10pm before storms move off to the east. The core of the 500mb low tracks directly over the region on Monday, stalling out as the synoptic pattern over the CONUS begins to slowly amplify. This will keep abundant cloud cover over the region and hold high temps in the lower to mid 70s. The slow approach of the vort max and deep cyclonic flow will maintain lift through the day, producing a flare-up of numerous showers as daytime heating provides a boost. Model soundings advertise a deep moist profile across the region and PWATs hovering in the 1.25 to 1.50 range, which along with relatively slow storm motion of around 25 mph may bring some localized heavier rainfall totals. There will be a chance for thunderstorms, but nearly moist adiabatic lapse rates will be a limiting factor for updraft intensity and severe weather is not likely tomorrow. Tuesday will be another showery, relatively cool day as the upper low continues to slowly pivot across the region. Similar moisture profiles and lapse rates will exist, so expect another day with scattered to numerous showers, a few thunderstorms, and potential for a heavy downpour at times. By the evening the 500mb closed low will open up to the broader scale troughing and begin to depart to the east with rain chances diminishing Tuesday night as upper geopotential heights begin to rebound. Surface high pressure builds into the area on Wednesday, promoting dry conditions and gradual clearing of any lingering cloud cover. A thermal trough may still be holding in the vicinity with 850mb temps around 10C to start the day, but highs should be able to reach the mid to upper 70s for most areas after a cooler start in the 50s. Higher forecast uncertainty arrives by Thursday into the late week as a strong ridge develops over the southern Mississippi Valley and directs a series of convectively enhanced shortwaves across the Midwest. With shortwave ridging residing somewhere near the Great Lakes, it's hard to say how far east these systems will progress before falling apart. Best chances for additional showers/storms in the extended forecast look to occur Saturday into Sunday as a more substantial upper trough swings across the region. MARINE... A strong low pressure system and attendant cold front and occluded fronts will approach the local waters from the upper Midwest into this evening. This system will bring widespread showers and a line of strong to severe thunderstorms to the local waters this afternoon and into early tonight. The main severe weather hazards will be wind gusts to or in excess of 50 knots, large hail in excess of 1 inch, and possibly a spin up waterspout. The best potential for severe thunderstorms will exist across the southern Lake Huron basin, including Saginaw Bay, as well as Lake St. Clair, and western Lake Erie. Outside of erratic winds and waves associated with thunderstorms, low waves will prevail into early next week. Moderate southeasterly winds will prevail through tonight with gusts generally under 20 knots. Unsettled weather will then prevail through early next week as the low pressure system slowly meanders across the region with winds gradually backing more northerly with time. HYDROLOGY... Numerous to widespread showers and thunderstorms will track eastward across the state late this afternoon and evening. The main line of storms will move out by around 10pm, but additional scattered showers are likely to continue overnight. High environmental moisture content will enable thunderstorms to produce heavy rainfall rates, though storm motion of 35 to 45 mph should prevent prolonged heavy rain at a given location. Storm total rainfall amounts through tonight are forecast to range from 0.75 to 1.25 inches with localized totals in excess of 1.50 inches possible. The potential for widespread flooding is limited by the rapid motion of the storms combined with the recent dry pattern over the area during the past couple months. However minor urban flooding and flooding of smaller streams will be possible. The low pressure system stalls over the central Great Lakes Monday and Tuesday leading to additional widespread showers with a chance for non-severe thunderstorms each day. Additional rainfall amounts of 0.25 to 0.75 inches are possible during this phase of the event. Dry weather returns by Wednesday and holds through Thursday. && .DTX WATCHES/WARNINGS/ADVISORIES...
