KEY MESSAGES
- Limited chance of showers today through Monday afternoon
- Medium/High Confidence in evolution of upper troughing this week
UPDATE
Issued at 1026 AM EDT Sun Jun 2 2024
Latest visible loop shows clearing moving south across the northwest cwa. Eventually we'll see the clearing make it south into Mid Michigan too, but probably not before mid afternoon.
Where the stratus is eroding, cumulus is quickly filling in.
Skies will become partly sunny this afternoon from north to south.
A couple of the CAMs continue to hint out a shower or two possible over the southeast cwa late this afternoon so we'll continue with a very low PoP there.
DISCUSSION

- Limited chance of showers today through Monday afternoon
Weak surface low pressure over central lower Michigan early this morning will shuffle east today. Moisture and clouds in the mid to upper levels will depart but remain in the low levels for some portion of the day. Areas of light drizzle may linger this morning over the middle of lower Michigan. Question will be how quickly does the low stratus mix and scatter into diurnal cumulus. Latest guidance more aggressive with sunshine this afternoon near/west of US-131, while some models including the HRRR leave areas near I-69 relatively gloomy where low level wind convergence and troughing hangs around a little longer on the backside of the low. Will keep about a 10 percent chance of measurable rainfall there this afternoon.
Near-normal temperatures today trend seasonably warm on Monday, while humidity will be a little more noticeable (dew points near 60). Upper level flow over the northern CONUS through Monday is fairly zonal but weak, with the next shortwave trough of note approaching Michigan late Monday. Cirro/alto clouds will be streaming in on Monday from upstream thunderstorms. The chance of showers and thunderstorms appears low until late in the day when better 850 mb moisture streams in and instability increases.
- Medium/High Confidence in evolution of upper troughing this week
Shortwave ridging early this week gives way to height falls by Tuesday as a closed upper low approaches from the northwest. This low figures in the evolution of persistent troughing across the Great Lakes by the end of the week with lower 500 mb heights and low level northwest flow indicating cooler than normal temperatures into next weekend.
As far as rain chances, they persist from Monday night through Wednesday in most southerly flow ahead of the upper low and should peak on Monday night as a shortwave trough minors out and again Tuesday night into Wednesday as a cold front will focus rain and embedded thunderstorms. Showery and cool under the upper low for late week and the weekend.
AVIATION /18Z TAFS THROUGH 18Z MONDAY/
Issued at 1230 PM EDT Sun Jun 2 2024
Conditions ranging from IFR to VFR will slowly improve to VFR at all the terminals this afternoon as cigs gradually improve. VFR conditions are then expected through the evening. Patchy fog will develop early Monday morning and bring potential for MVFR/IFR conditions at times. Any fog will dissipate by mid to late morning with VFR conditions expected at all the terminals from late Monday morning into the afternoon.
MARINE
Issued at 312 AM EDT Sun Jun 2 2024
Limited potential for hazardous conditions in the nearshore Lake Michigan waters today and during the day Monday. Some patches of fog may be present this morning. Winds will be from the northwest and light today, and a little breezier from the south on Monday.
Thunderstorms may occur over the water between Monday evening and Wednesday.
