SC

Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
317 AM EDT Tue Apr 3 2018

.DISCUSSION...

No fundamental changes to the forecast for today, the morning
package mainly reflecting refinements to precip coverage through
early afternoon and high temps based on expected northward progress
of the warm front. Thunderstorms are ongoing along a line from Saint
Louis to Louisville within the convergent corridor associated with
the surface warm front that extends east from a 989mb sfc low in SW
Kansas. This activity will remain well south of the CWA through most
or all of the day. Instead, theta-e advection up the warm frontal
slope will gradually result in elevated destabilization beginning
near the Ohio border at press time and extending toward the Thumb
and Saginaw Valley by early afternoon. Lack of organized forcing
through early/mid afternoon preclude categorical pops, though any
small scale forcing should have no issue triggering showers. Thus,
chc-likely pops are in place areawide from into early afternoon.
Confidence in at least some activity is increased by consensus
among the suite of hi-res guidance.

06z RAP indicates 60kt LLJ impinging on southern portions of the CWA
mainly after 21z. In addition to sharpening the mid-level front,
convergence along the nose of this jet will be impressive. With the
column destabilized by this point, and MU parcels featuring 500-1000
j/kg CAPE, confidence is high that widespread convection will
develop and track east across the area roughly 21-03z. PWATs
rounding out around 1 to 1.25" and progressive nature of forcing
suggest limited flooding potential as QPF will likely stay around an
inch or less in most areas. However, locally heavy downpours will
lead to ponding on flood prone roads. Deep layer isentropic ascent
within the resident right entrance region will ensure coverage
extends north regardless of where the strongest mid-level convergence
sets up. Categorical pops are therefore in place late this
aftn/evening. Clouds and precip will keep temps suppressed in the
30s and 40s. The surface warm front will encroach on the southern
tier of counties after sunset, leading to a low potential for a
short-lived late day run at 50 or even 60 before midnight for
Lenawee and Monroe Counties. Any such entrance into the warm sector
would present a marginal risk for surface-based tstorms to produce
wind gusts to 60 mph given the magnitude of wind through the column.

Cold advection will be underway as the dry slot fills in overhead in
the wake of the surface low. Periods of drizzle 03-09z will be
possible before cold sector moisture pivots into the area with
deformation associated with the mid-level wave squeezing out another
tenth or two of QPF. Cold sector precip will fall as snow, though a
very warm column will limit snow ratios to no better than 10:1,
falling to around 0 a couple hours after sunrise given low rates and
solar radiation. Expect no more than an inch or two, mainly north of
M46.

Hudson Bay vortex will hold firm for the remainder of the week
yielding below normal temperatures through the forecast period.
Occasional disturbances embedded within cyclonic northwesterlies
will bring occl ra/sn episodes, the next of which is modeled to
pivot through SE Michigan late Thursday/Thursday night.

&&

.MARINE...

Northeast winds strengthen today as low pressure encroaches from the
west. Winds will then back to the north and then northwest tonight
into Wednesday as this low passes through the southern Great Lakes.
The onshore flow will lead to elevated wave heights through the
nearshore waters of Lake Huron with small craft advisory conditions
expected from midday Tuesday into Wednesday. Gale force gusts will
also become more likely by tonight as the deepening low pressure
system passes through the area. Gale force gust potential will
persist into Wednesday as cold and unstable northwest flow surges
into the area in the wake of this low pressure. A Gale Warning has
been issued for parts of Lake Huron.

&&

.HYDROLOGY...

Rainfall potential increases through the daylight period, becoming
widespread from mid afternoon into the evening hours. While overall
rainfall averages should range generally between one half and three
quarters of an inch, a few thunderstorms will bring the potential
for locally higher amounts on the order of one inch this evening.
Aside from ponding of water within poorly drained areas, these
amounts will not be sufficient to produce any flooding.
Colder air filtering into the region may bring a transition to light
snow Tuesday night and early Wednesday before precipitation ends.

&&

.PREV DISCUSSION...
Issued at 1151 PM EDT Mon Apr 2 2018

AVIATION...

Deep baroclinic zone from 925-500mb will progress steadily northward
overnight lifting into the state during the latter half of the
night. Top down saturation will commence under deep isentropic lift.
Residual low level dry air will be slow to scour out initially, but
will finally give way to a moistening column by mid to late morning.
Rapid transition from MVFR to IFR is anticipated after daybreak
Tuesday. Bulk of the event will be a straight rain precipitation type
for most of the forecast area. A brief wintry mix of -fzdz/-fzra/-sn
will be possible at FNT and MBS at onset. One uncertain part of the
forecast is that snow my be hold as the predominate precipitation
type at MBS for a few hours into the morning Tuesday. Warm
temperatures will limit the impact. Elevated thunderstorms will be
possible over Southeast Michigan, particularly during the late
afternoon/early evening south of the I69 corridor. Confidence in
coverage and timing remains low and will keep the mention out of the
TAFs.

For DTW...Precipitation will advance within vicinity of the airspace
after 10z Tuesday. A very low chance exists for a brief mix of -sn/-
fzdz at precipitation onset. However, this chance remains very low
and predominate precipitation type will be rain. Most favorable time
period for Thunderstorms will be 22Z Tuesday - 02Z Wednesday.

/DTW THRESHOLD PROBABILITIES...

*  Low for ceilings aob 5000 this evening. Medium after midnight,
   high after 10z.

*  High for precipitation type to remain mainly rain Tuesday. Brief
   window for -sn/-fzdz at onset Tuesday morning.
