LATEST UPDATE . Synopsis/Discussion/Marine

SYNOPSIS. Issued at 330 PM EDT Sun Apr 18 2021

-Cold front comes through Monday, chance of rain

-Accumulating snow threat Tuesday night trending south/lower

-Hard freeze risk Wednesday and Thursday mornings

DISCUSSION. (This evening through next Sunday) Issued at 330 PM EDT Sun Apr 18 2021

--Cold front comes through Monday, chance of rain--

Model guidance has been trending toward an earlier cold frontal passage on Monday, with chilly temps and rain chances developing sooner. Warmest high temps of 55-60 Monday will be south and east of GRR, occurring in the early afternoon will a cooling trend and chance of rain following after that.

Meanwhile places north and west of GRR will probably be stuck in the 40s all day as considerable low cloudiness and areas of light rain come in behind the front that passes through quite early in the day.

The chance of light rain on Monday night becomes limited to areas south of a Holland to Lansing line and mainly in the evening, as the front continues to sag south. The rain could mix with or change to light snow after dark but sfc temps too warm for any impacts.

--Accumulating snow threat Tuesday night trending south/lower--

Over the last couple model cycles there has been a southward shift to the swath of accumulating snow Tuesday night in both deterministic and ensemble guidance. This aligns with the quicker cold frontal passage Monday which subsequently settles farther south before the wave moves northeast along it.

The 12Z NAM solution is the farthest north and most aggressive, and is now an outlier with most other guidance. It is suggesting 6+ inches south of a Holland to St Johns line, whereas most other guidance has lighter accumulations, and mainly only south of a BTL to LAN line. The UKMet model actually misses the GRR CWFA completely with snow on Tuesday night.

The jet energy which helps to dig/carve out the longwave trough on Monday and Tuesday - and ultimately develop the sfc wave on the front Tuesday night - is still way up in British Columbia. So suspect we will continue to see some adjustments/wobbles in the low and snow track going forward. This is definitely still a "stay tuned" type of event for srn Lwr MI.

--Hard freeze risk Wednesday and Thursday mornings--

Regardless of what occurs on Tuesday night with the potential snow, confidence is high that a widespread hard freeze occurs on both Tuesday night and Wednesday nights. This is when the deep upper trough is overhead and strong cold advection is impacting the area.

Expected lows in the mid 20s are critical temps for causing damage to budding fruit trees, but the northwest flow off Lk MI could lead to less severe conditions in the wrn lwr MI fruit belt. The winds actually look rather strong/blustery on Wednesday, with some gusts of 30-35 mph.

Temps return back to near normal for the end of next week and next weekend after the upper tough lifts out. The retuning warm air may generate some rain chances next weekend.

AVIATION. (For the 18Z TAFS through 18Z Monday afternoon) Issued at 123 PM EDT Sun Apr 18 2021

Fair weather will continue this evening before mid clouds advect into the state. A cold front will drop south Monday morning bringing some rain or mixed rain/snow with it. Soundings near the sfc will be above freezing but fall below 0c above 950 mb.

MARINE. Issued at 330 PM EDT Sun Apr 18 2021

Increasing southwest flow tonight ahead of approaching cold front, followed by west-northwest flow behind the front on Monday, will build waves 2 to 4 feet. Winds will be mostly offshore/northeast on Tuesday, but will increase dramatically out of the northwest on Wednesday when Small Craft Advisory will likely be needed. Winds could even flirt with gale force on Wed.
