- Small chances of snow North today and Wednesday
The couple of chances of snow up North that we will see today, and then again Wednesday, will be associated with a couple of different short waves brushing the area. The circumstances will be far from ideal with each of the waves to bring much more than a couple of tenths of an inch across the North.
The first wave approaching the area today is coming in from the WNW.
The first thing going against much precipitation from this wave is it is expected to shear out as it drops through the area today. In addition, deep moisture is never really in place. We initially had some low level moisture that is making its way out currently. By the time the mid/upper level moisture lowers enough, there is no low level moisture to help it reach the ground. The best chance where these layers of moisture will overlap enough to get some snow at the sfc will be across the U.S.-10 corridor this morning.
The snow chances then end this afternoon as the wave and moisture moves by, leaving some short wave ridging in place. Then later tonight into Wednesday, we will see the next short wave approach the area from the NW. This wave will remain intact and even strengthen a bit as it approaches. The problem with this wave for precipitation chances is that the track of it just barely brushes our northern counties again. Moisture is once again limited for most of the area, with just a thin layer up around 4-5k ft, and no real depth in our area.
- Medium to High Confidence for Snow/Mix Late Week
Upper troughing will extend south into the Great Lakes from the polar vortex across Hudson Bay by Thursday. An area of snow blossoms in a baroclinic zone across the NW CONUS/SW Canada on Wednesday and moves southeast along the arctic front, arriving in Lower Michigan by late Thursday night into Friday. Models are converging on the evolution of a sfc wave forming along the front, leading to higher confidence in the chances for some measurable snow. The surface low is progged to shear out and weaken, becoming an open wave by Friday with snow and mixed precip diminishing, but it appears that the timing of the snow will impact travel for the morning commute.
- Low Confidence on Storminess early Next Week
Western CONUS troughing amplifies and goes negative tilt early next week and a surface cyclone will evolve over the Plains. Ensemble spread is significant on the details of how this evolves. The current forecast is most reflective of the GFS with a less highly amplified solution and snow arriving on Sunday, changing to rain on Monday. The more amplified, blocky solutions of the ECMWF and GEM would hold off precip until Monday or Tuesday.

Issued at 147 AM EDT Tue Mar 19 2024
VFR conditions will continue through Wednesday evening. Stratus deck will prevail with bases around 3500 to 5000 feet AGL this morning. West winds will gust over 20 kts this morning then go northwest in the afternoon.
MARINE
Issued at 338 AM EDT Tue Mar 19 2024
We will be holding on to the Small Craft Advisory, and extending it yet again through Wednesday night.
We did give some consideration to upgrading to a Gale for today, but ultimately decided that the it is a marginal situation for too short of a duration.
Winds will diminish slightly tonight as one core of wind moves out, and then another will move in on Wednesday. We could be flirting with Gales once again, but the situation looks even less favorable than the marginal scenario today. Winds will finally diminish Wednesday night, with waves falling below criteria by Thursday at 12z.
