607 am edt Mon mar 18 2019

Aviation
Dry low level environment within light northwest flow will ensure
vfr conditions through the TAF period. Window of clear sky this
morning, before a sct bkn coverage of late day diurnal CU emerges as
lapse rates increase within this cooler march environment. This
cloud deck fades with loss of heating, but pattern remains favorable
for additional higher based cloud to lift into the area overnight.

For dtw... Late day diurnal stratocu will carry CIGS within the 5000
to 6000 ft level.

Dtw threshold probabilities
* medium for ceiling AOB 5000 ft this afternoon and evening.

discussion...

near term today through tonight
as of 320 am edt... Generally quiet conditions continue across
southeast michigan early this morning outside of a few isolated snow
showers that will continue to diminish over the next few hours. This
activity will have negligible impacts with just a dusting at best
expected.

Latest water vapor satellite imagery continues to indicate broad
longwave troughing over the eastern conus, with multiple, largely
disorganized pieces of embedded shortwave energy moving through the
longwave pattern currently across the great lakes. The exception
will be a remnant northern stream jet streak that will dive
southeast towards the region for this afternoon and evening, and
will provide just enough of a lifting mechanism coupled with daytime
heating to promote widely scattered rain snow showers roughly 4pm-
10pm. As with activity early this morning, these showers will
largely be inconsequential and may even resemble more in the way of
sprinkles as they fall out of a broken stratocu deck expected to
develop this afternoon. A well-mixed boundary layer extending up to
5-6 kft coupled with march Sun will likely aid in slightly
overperforming temperatures today, with lower 40s possible across
most areas outside of the thumb.

Remnant isolated shower activity will hang on in the eastern thumb
through late evening, and transition over to snow showers as
temperatures fall back through the 30s. Loss of daytime heating will
offer the opportunity for skies to clear out around midnight, before
some high clouds associated with a piece of shearing vorticity
swings through towards daybreak Tuesday. Strengthening surface high
pressure over the ohio valley coupled with developing confluent
northwest flow aloft will result in increasingly stable conditions
for much of the night. Low temperatures will be limited to an extent
by a light southwesterly flow, settling in the 20s.

Short term Tuesday through Wednesday night
confluent northwest flow aloft persists through Tuesday with dry and
quiet conditions across the region. The surface high will slide east
towards the mid-atlantic region allowing for southwesterly return
flow to increase slightly (although still remaining light), and
despite another round of bubbling boundary layer stratocu during the
afternoon hours, high temperatures should be a few degrees warmer
than today and warm well into the 40s for most areas. Mid high
clouds will then be on the increase Tuesday night ahead of a surge
of northern stream PV racing south from hudson bay and limit low
temperatures closer to freezing.

As the ribbon of northern stream PV races south Tuesday night,
shearing energy exiting east from the central plains will interact
and help spawn a weak clipper-type low at the surface for the day
Wednesday that will track northeast of the region. An associated
frontal boundary will track southeast across lower michigan, and
enough moisture will be present to result in at least chance wording
for pops. Increasing pressure gradient ahead of the frontal boundary
will result in a breezy day Wednesday, with 20-30 mph gusts common.

These southwesterly winds will help temperatures push 50 resulting
in precipitation falling as rain. Depending on the timing of the
frontal passage, which currently looks to hold off until late
Wednesday night, lingering showers may transition to a mix of
rain snow with no accumulation. Low temperatures Wednesday night
will settle in the low to mid 30s.

Long term Thursday through Sunday
the long term portion of the forecast will be characterized by
highly amplified flow across north america, with a quasi rex block
pattern setting up over the western CONUS heading into the weekend.

Southeast michigan will be on the eastern side of strong upper-level
ridging resulting in a extended period of dry weather beginning
Thursday and continuing through the weekend. The first day of spring
is Wednesday march 20th, and the weekend will shape up to be an
excellent start with abundant sunshine and temperatures in the 50s.

Marine...

high pressure will remain over the region today and Tuesday. This
will maintain a stretch of quiet weather with light winds and
limited wave action in ice free areas. Southwest winds will
strengthen Tuesday night into Wednesday as the pressure gradient
increases in advance of a cold front. Gusts to 25 knots during this
time. Winds shift to northwesterly and diminish with the frontal
passage Wednesday night. Moderate northwest winds will prevail
through Thursday.
