KEY MESSAGES

- Mostly sunny and mild today/Monday

- Risk for Thunderstorms Remains Late Tuesday into Wednesday

- Turning Cooler Late Next Week



DISCUSSION
Issued at 314 AM EDT Sun Apr 14 2024

Discussion reissued with corrected content below...

- Mostly sunny and mild today/Monday

Interesting little system moving across northern Wisconsin/northern Lower early this morning. A strong surge of warm air aloft coupled with robust mid level lapse rates is helping to produce showers/storms over northern Wisconsin/northern Lower. Present indications are such that almost all of the rain will remain north of the cwa, but it's possible that the northern row of counties could get clipped with a few showers.

We'll be solidly in the warm sector today and temperatures will respond by climbing into the lower to mid 70s before the trailing cold front moves through later this afternoon.

High pressure will build into the region Monday rendering clear skies and slightly cooler temperatures compared today. However, highs in the upper 60s will still be 10 degrees or so above normal.

- Risk for Thunderstorms Remains Late Tuesday into Wednesday

An upper jet at 250 mb is currently digging into CA/NV and will move east over the coming days, strengthening as it does so. By Late Tuesday into Wednesday, Lower Michigan is likely to be positioned in the left exit region of this upper jet, with upper divergence present overhead. At 500 mb, models continue to forecast upper low development over the Rockies and central Plains by late Monday into Tuesday with a low level jet developing as well as surface cyclogenesis. Surface low occlusion is forecast to quickly take place shortly thereafter across the Midwest by Tuesday night. This low is expected to track over Lower Michigan Wednesday. The GEFS/CMC/ECE probabilities for measurable rainfall during this period from Tuesday night into Wednesday is 90%-100% region-wide.

During the day Tuesday, not much may be happening as we await warm air advection aloft and a rise in low level moisture. This may be delayed until late in the day. Areas south of I-96 are most at risk for some showers primarily after 18z Tuesday. Model trends seem to be delaying this threat a touch so in a reality much of the region may stay dry for a good portion of the day before a surface warm front is slated to arrive Tuesday night. It is during the 00z-06z Wednesday time frame that the environment may start to be conducive to some showers and elevated thunderstorms.

Showers and some thunderstorms are likely to be ongoing at the start of Wednesday morning. The ECMWF and GEM have slightly slowed the arrival of a surface cold front across the region Wednesday afternoon, which may give areas especially near and south of I-96 a chance to build some surface based instability depending on what happens with the morning activity. Numerous ensemble members as well as the deterministic runs of the GFS and GEM show the potential for 1000+ J/kg of SBCAPE to develop. Tough to say at this point whether this will be reality, but the risk is certainly there. Fairly strong winds aloft at 850 mb (40 kts) and 500 mb (40-50 kts) could be tapped with any convection that develops, though deep layer shear does not look overly impressive at 30-35 kts. Still, thunderstorms with strong wind gusts look to be the main hazard on Wednesday. With a warm front lifting at least as far north as I-96, we'll also have to watch for potential for any surface based storms that can tap into extra low level shear and storm relative helicity along that boundary.

- Turning Cooler Late Next Week

GEFS mean 500 mb heights indicate troughing will be dominant across the Great Lakes late in the week and weekend. Cold air advection at 850 mb looks to be slow but steady from Thursday into the weekend.
Declining temperatures at the surface can be expected during this time as highs retreat into the 50s Thursday and Friday, then possibly 40s for Saturday. Periodic rain showers are possible during this time. Depending on cloud cover over the weekend, frost/freeze conditions may develop.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/
Issued at 122 AM EDT Sun Apr 14 2024

LLWS is well underway overnight as a 55 kt low level jet spreads over the region, in the midst of weaker surface level flow. Wind shear of 45-50 kts at 2000 ft can continue to be expected. This threat will diminish in the 12z-14z time frame. Shower and thunderstorm activity across NE Wisconsin and NW Lower Michigan should stay north of all terminals overnight, but will maintain a weather watch over Lake Michigan to see if any rogue showers or storms develop south of that cluster of storms. Current odds are low.

MARINE
Issued at 302 AM EDT Sun Apr 14 2024

Waves will continue to diminish this morning...but may start off in the 3-4 foot range from St Joe to Holland before decreasing to 1 to 3 feet.

Winds will increase again ahead of a strong low Tuesday and a Small Craft Advisory and potentially a Gale Warning may be needed Tuesday through Thursday.

GRR WATCHES/WARNINGS/ADVISORIES
MI...None.
