.aviation /06z sunday through thursday/...
fairly widespread mvfr ceilings are observed across the region
with a few pockets of vfr for the southwestern terminals and
ifr/lifr to the east behind the departing rain showers. ceilings
are expected to become mainly ifr to the west and mvfr to the
east over the next few hours behind the front. there are
signals of lowered visibility across the western terminals west
of i-77 this morning due to patchy fog with ceilings of less
than 1kft. conditions will improved slightly by 12-15z this
morning, but will still remain at least mvfr. rain showers will
move into the region this afternoon, though still anticipate
mvfr ceilings with isolated reduced visibility.

winds across the region are around 5 knots out of the south at
most locations, with keri seeing around 20 knots sustained with
gusts up to 30 knots due to downsloping. winds will shift around
from the south to the southeast with the rain showers, then
become westerly behind, still light at less than 10 knots.

outlook...non-vfr possible with lingering rain showers and lower
ceilings sunday night into monday morning. non-vfr possible
with rain showers on wednesday.

winds have subsided across the eastern basin of lake erie down to 5-
10 knots out of the south to southeast. today, a cold front will
pass across lake erie and winds will shift to be out of the north at
5-10 knots. light winds, at less than 10 knots, with waves 1 foot or
less are expected across the lake through wednesday evening as high
pressure builds into the region.

overnight with the low level moisture (dew points in the mid
50s) have seen some patchy ground fog and mist develop with
several reported automated visibilities dropping to 2 to 3
miles. with the incoming disturbance moving eastward still over
il as seen on regional radar mosaic, anticipate an uptick in
moisture advecting from the south ahead of the system. this
could cause an increase in the mist and fog as this happens.
will continue to monitor conditions this morning. the almost
calm winds so far has mitigated the fog coverage and thickness
with lack of mixing.

this system will increase chances for rain showers and embedded
thunderstorms as the disturbance moves into the cwa this
morning. severe thunderstorms are not expected with these storms
with the very limited shear/forcing. there is a bit of
disagreement among guidance with how fast this disturbance moves
through and begins to clear out but the western portions of the
area should see the rain showers coming to an end after 2-3 pm
edt and areas further east would be several hours later. highs
today will top out in the 70s across the area.

with ridging pushing in behind today`s disturbance, memorial
day holiday is setting up to be a fairly decent day weather wise
with warmer temperatures (highs in the low 80s) and clearing
skies. may be a bit sticky for some as dew points will remain in
the 50s.tuesday looks to be in similar shape with just a few
degrees warmer for high temperatures and becoming slightly more
humid by tuesday afternoon (td`s in the low 60s) with moisture
pushing northward once again with a boundary set up just to the
south of the cwa gets displaced northward with a building
bermuda high. wednesday we see chances for showers/t-storms
across the area increase with this intrusion. a passing longwave trough
over eastern canada and the northeast does push back on this
moist airmass back to the south. a high amplitude ridge looks to
set up over the central conus and gets well up into central
canada by thursday. this will set up our area for a return to
dry conditions with high temperatures above to slightly above
normal into next weekend as this pattern is shaping up to be a
bit of an omega blocking set-up which will slow down the
progressive pattern.

mvfr to ifr conditions expected at the taf sites this period,
with lifr possible this morning as moisture increases/advects
northward ahead of the incoming disturbance pushing eastward
into the region. cigs/vsbys drop with mist and ground fog
development. rain chances increase once again with the
approaching disturbance and also an increase in thunderstorm
potential after 12z for ksbn and after 15z at kfwa. winds shift
behind the system to the west- northwest, with ceilings lifting
towards mvfr/vfr in the later afternoon/evening. however, some
uncertainty with guidance disagreement in how fast the
improvements will arrive.

saturated near surface conditions will maintain ifr to mvfr cigs
through the morning hours prior to daybreak. ceiling heights improve
after sunrise and through the early afternoon. passage of a cold
front to then bring a broken line of showers with possible embedded
thunderstorms from west to east, with timing ranging from around 18z
to 23z. wind direction veers northwest in the wake of the front
along with clearing trends as mid-level clouds advect east. timing
of the clearing along with how well the line of showers holds up as
it traverses se mi this afternoon will dictate fog chances
overnight, along with the degree of visibility restrictions.

d21/dtw convection...a line of showers and thunderstorms will be
possible between 20-23z sunday. no severe weather is expected.

.dtw threshold probabilities...

* high for ceilings at or below 5000ft this morning.

* medium for thunderstorms sunday afternoon.

cool, cloudy start to the day following the slow departure of
friday`s low. active pattern set to continue today as midwestern
troughing is quick to flow, lifting a warm front into se mi this
morning. the fairly diffuse accompanying gradient keeps
southwesterly winds on the lighter side however, limiting the
magnitude of warm advection and moisture transport into the area.
this is looking to result in both warmer temperatures (around 70)
and higher dewpoints (lower 60s) only able to reach up around the m-
59 corridor before the arrival of upstream convection early this
afternoon. several hundred j/kg of sbcape are progged to be in place
over these southern areas offering scattered thunderstorm chances
within the broader shower activity. given bulk wind shear values
creeping into the lower 30kt range, can`t completely rule out an
isolated strong cell however the marginal instability and weak lapse
rates (<6.5 c/km) will act to keep convection in check. for areas
north of m-59, sufficient instability will be difficult to come by
as dewpoints are favored to remain in the 50s with temperatures in
the mid 60s. this has been picked up on in the latest cam guidance
with a trend towards decaying showers on the northern flank.
lingering rain ends around 00-01z as the attendant weak cold front
clears the region.

high pressure rapidly builds over southern lower mi tonight
supporting clearing skies going into memorial day. high center
drifts over toledo to lake erie over the course of monday ushering
in light southwesterly return flow. in combination with sunnier
skies, highs return back to the upper 70s to mid 80s- warmest in the
tri-cities where the strongest waa is focused. an isolated pop-up
(thunder)shower is possible over the saginaw valley late afternoon-
evening as several hundred j/kg of mlcape develop. otherwise, dry
weather holds across the area through tuesday due to the influence
of high pressure. next chances for some scattered showers and
isolated thunderstorms arrive daytime wednesday as a backdoor cold
front sweeps out of lake huron through se mi. high pressure then
builds back in to close out the work week.

marine...

the low that passed over the region on saturday will pull away to
the east today but a mid level system will drive another front
through the region today resulting in a chance of afternoon showers
and thunderstorms for a few hours. winds will become southerly by
morning and southwesterly this afternoon behind the warm front.
gradient is weak thus winds are expected to hold at 10 knots or
less. high pressure then starts building into the region tonight
which will slowly pass eastward monday and tuesday keeping the
weather quiet with light winds and waves. the high will reach the
mid-atlantic coast by wednesday with the great lakes then residing
just north of a low over the ohio valley. a cold front will dropping
southward through the region late wednesday which could result in
some showers.

hydrology...

a cluster of showers and thunderstorms is forecast to track west to
east across the area this afternoon. most areas will receive under a
quarter inch of rainfall, but there will be the potential for some
areas to see up to 1 inch dependent on thunderstorms. this would be
most likely to occur south of m-59. overall dry conditions over the
past 30 days suggests the potential for flooding is low, aside from
typical isolated flood prone locations in urban areas.
