- Quiet Weather Through Monday Night

- Risk for Thunderstorms Remains Late Tuesday into Wednesday

Issued at 311 PM EDT Sun Apr 14 2024

- Quiet Weather Through Monday Night

A cold front will continue to press off to the south and east of the forecast area tonight. At 19Z it was situated from portions of Southeast Lower Michigan southwestward into Northern Indiana. Dew points have fallen into the 30s in our northern CWA across Central Lower Michigan behind the front. The drier air will set the stage for temperatures to fall to near seasonal normals in the upper 30s to middle 40s tonight. Certainly a chance to drop below those forecast values and we will be watching conditions this evening.

High pressure will drift from west to east across the area Monday and Monday night which will allow a warm front to approach from the southwest heading into Tuesday morning. We will remain dry though through Monday night. Mainly 60s for highs on Monday.

- Risk for Thunderstorms Remains Late Tuesday into Wednesday

There continues to be good agreement amongst the models and ensemble members that rain chances will increase quickly later Tuesday and Tuesday night. This means that there will be a decent period of dry and mild weather before the rain moves in.

The main focus of the rain will be a 50+ knot low level jet that will nose over the area beginning later Tuesday afternoon. Right now, it just looks to be mainly rain showers with a small chance of thunder. Convective instability is shown to be fairly weak to nil with this leading edge of rain. The rain showers and isolated thunder should taper off late Tuesday night/Wednesday morning.

We are likely to be in a relative lull for the first half of the day on Wednesday, before additional showers and a better chance of storms move in Wednesday afternoon and evening. The way that the sfc front moves in, and then how another short wave aloft rotates around the bottom of the long wave trough/low, another wave of showers/ storms will likely develop to our WSW and move in. There is a bit better instability expected to move in ahead of the next wave as the cold pool aloft and short wave move in. Right now, it looks like a lot of residual cloud cover will hold in, limiting the amount of diurnal heating that can take place.

There is still some concern that some severe weather will be possible with this Wednesday afternoon wave. That is because it appears based on sfc instability and temp progs that a triple point may traverse the southern portion of the area. There looks to be a low level jet associated with this wave that will nose up to the I- 94 corridor. Deep layer shear will be plentiful with stronger upper level winds. Still quite a bit of uncertainty with the exact track as it could nudge north or south. Definitely bears watching.

- Turning Cooler Late Next Week

We will definitely see this system create a pattern change to the mild weather this weekend and expected early in the coming week. The active southern branch of the jet sinks well south of the area. This will lock up the good warmth and unstable conditions. We will end up with long wave upper troughing settling in over the area from Thursday though most of next weekend.

Rain chances are not that impressive for Thursday and beyond, but unsettled and cool weather can be expected. The cooler air aloft and weak impulses in the trough could bring some lower chances of a few showers at various times. Most of the time though it will just be cool and dry. Details are way too tough to try and pinpoint at this juncture.

Issued at 730 PM EDT Sun Apr 14 2024

Very high confidence in VFR conditions throughout the TAF period as SKC is expected at all TAF sites for the next 24 hours, except for a few passing mid-level clouds that may briefly clip terminals overnight. West- northwest winds of 10-15 knots become north winds at or below 5 knots overnight before becoming westerly around 8-13 knots Monday afternoon.

Issued at 311 PM EDT Sun Apr 14 2024

We dropped the Small Craft Advisory at midday as winds and waves were in the process of falling below advisory criteria. All nearshore observations (wind) and buoys (Muskegon) are all showing conditions below criteria. Webcams also show waves have fallen considerably. The Muskegon buoy has waves down to 2.3 feet as of 1:40pm.

With surface high pressure in the area for the rest of this afternoon, tonight, Monday and into Monday night no headlines are planned through Monday evening.

The next time frame of concern on the big lake is Tuesday night through Wednesday night as low pressure approaches and moves through the area. Initially southeast winds will be in place shifting to the southwest and west with time. With offshore winds initially and then along shore, it will mainly be a wind issue as fetch will be limited. Waves come more into play Wednesday afternoon and night as the flow becomes more onshore.
