.DISCUSSION...
Issued at 240 PM EST Tue Mar 4 2025

- Rain Moves Back in Tonight; Isolated Storm Possible Wednesday

The short break in rain is coming to a close and more rain will
move in this evening as well as tomorrow. A deepening area of low
pressure moves overhead by tomorrow with minimum central pressure
possibly getting down into the upper 970s mb, which is quite low.
Given the track of this system, we will be solidly in the warm
sector through Wednesday afternoon with highs expected to reach
the 50s. The 12z HREF shows surface based CAPE building after 15z
Wednesday with 100-200 J/kg. 12z HRRR soundings reveal that while
we're in the warm sector, a few hundred J/kg of SBCAPE are
possible as a few low topped thunderstorms may develop in the
midst of no convective inhibition, at least from what the HRRR is
indicating. As such, we are adding a slight chance for
thunderstorms to the forecast for Wednesday (SPC already has us in
the General Thunderstorm outlook). Other than some lightning, any
storms that develop are not expected to be significantly
impactful.

We continue to expect area rivers and streams will be able to absorb
the anticipated rainfall amounts of 0.75"-1.25" with little to no
issue, though rises will occur. Some of the snowpack across the
Muskegon River basin will melt off into the rivers and add to the
amount of water going into the overall basin, while some may still
remain and take in the rain more like a sponge. Either way, the most
likely scenario is that we hold all rivers below flood stage through
this event.

- Windy and Colder with Some Light Snow Wednesday PM, Thursday AM

Temperatures fall from the 50s Wednesday afternoon down into the mid
to upper 20s Wednesday night with rain changing to snow. The snow
won't last long enough to accumulate more than an inch or so, but
given the abruptly falling temperatures there could be some icy
spots on roads for the Thursday morning commute as leftover
puddles may freeze and a light coating of snow could cause some
slippery conditions especially on less traveled roads.

The pressure gradient on the back side of the departing low will
crank up winds as cold advection gets underway. Both CAMs and medium
range guidance all agree on excellent potential for 40+ mph gusts
area wide after dark Wednesday night and continuing into Thursday.
The highest gust potential of 45-50 mph looks to occur across our
lakeshore region during this time. These gusts could cause some
small branches to come down leading to a few power outages.

- Snow Showers Possible Friday, Mainly South of I-96

Ensemble and deterministic guidance is split on the outcome for
Friday as an upper wave exiting the Rockies moves east and tries to
phase with upper troughing across the Great Lakes region. A surface
low underneath this feature is likely to move east in a weakening
fashion and upper heights may be amplified enough to shunt this
feature south of our region. Nevertheless, there is enough ensemble
support (mainly from the GEFS) to include a risk for snow showers
primarily south of I-96 Friday. If the northern solution of the GEFS
verifies, an inch or two of snow could occur (probabilities for 1"
or more are shown to be 60-70% from the GEFS). The ENS shows this
outcome is less likely, with a 20-30% probability.

- Warming Temperatures Early Next Week

Rising upper heights and 850 mb temperatures increasing into the +5
to +10 C range could help boost surface temperatures into the 50s or
even 60s by next Tuesday and Wednesday. The majority of ECE members
currently have highs reaching the 60s during this time frame.
Ensemble guidance does suggest an upper wave could move through as
this early spring warmth makes an appearance, and this could bring
about an increase in rain chances by the middle of next week, with
some thunderstorms not out of the question.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 106 AM EST Wed Mar 5 2025

MVFR conditions prevailing overnight as widespread rain moves
through, with areas of IFR also possible after 09Z as a warm
front approaches from the south. Showers becoming scattered after
12-13Z once the warm lifts through and the cyclone dry slot
arrives.

Showers increasing again this afternoon and conditions remaining
mostly MVFR as the upper level low arrives. Will have to monitor
thunder potential for this afternoon as any sunshine could lead to
a few CBs but left that threat out of the TAFs for now. Cold
front arrives after 00Z tonight, with rain showers becoming mixed
with or changing to snow by Midnight.

LLWS continuing until 12-13Z with southeast winds to 50 kts at 2K
ft, ending with the passage of the warm front. Sfc winds becoming
gusty to 25 kt out of the south on Wednesday before shifting
northwest and increasing further Wednesday night with some gusts
to 35 kts possible by Midnight. Strongest winds at MKG.

.MARINE...
Issued at 228 PM EST Tue Mar 4 2025

A Gale Warning is being issued to handle the increased winds
expected on the back side of the departing storm system tomorrow
afternoon into Thursday morning. Northwest gales could approach
45 kts at times and help generate very large wave activity of 15
to 19 feet during this period. Hazardous winds and waves are still
expected Thursday afternoon which would impact small craft.
