sw`erly to w`erly flow aloft and embedded shortwave troughs
affect our region through memorial day. at the surface, a
primary low should wobble ne`ward from northeastern ar late this
afternoon to near central in by daybreak saturday before
wobbling farther ne`ward to near central lake huron by daybreak
sunday. the low should then wobble e`ward to near the gulf of
maine by memorial day. this low track should allow a surface
warm front to drift ne`ward through our region during the
daylight hours of saturday through saturday night, while a weak
cold front should sweep generally se`ward through our region
late saturday afternoon through sunday night. behind the cold
front, a weak surface ridge should build from the northern and
central great lakes through memorial day.
periods of rain, steady to heavy at times, continue to overspread
our region slowly and generally from the south the rest of this
afternoon through tonight as isentropic ascent occurs along the
upper-reaches of the warm front and taps into rich low-level
moisture originating over the southern gulf stream and gulf.
occasional and isolated thunderstorms are possible as the
isentropic ascent releases weak instability. on saturday through
sunday night, additional periods of rain, steady to heavy at
times, are expected due to the following: moist isentropic
ascent along the upper-reaches of the warm front and ahead of
shortwave trough axes aloft; low-level convergence/moist ascent
along the surface warm and cold fronts. these lifting mechanisms
may release weak, yet sufficient instability to trigger
additional isolated thunderstorms. widespread rainfall totals of
1 to 2 inches are expected today through sunday night. as
rainwater runoff enters area creeks and rivers, some waterways
(e.g. killbuck creek in holmes county) should rise to minor
flood stage this weekend. minor flooding is possible in poor
drainage and/or low-lying areas as well. forecast confidence
regarding widespread minor flooding remains low, which has
precluded the issuance of a flood watch for any part of our cwa.
on memorial day, current odds favor dry weather as stabilizing
subsidence accompanies the aforementioned surface ridge.
however, isolated showers and thunderstorms associated with the
upper-reaches of the departing cold front may impact roughly the
southeastern-third of our cwa.
overnight lows should reach the upper 40`s to lower 50`s in nw
pa and the 50`s in northern oh around daybreak saturday as
abundant cloud cover associated with the aforementioned low
pressure system and net low-level waa ahead of the surface warm
front contribute to limited nocturnal cooling. given the
projected evolution of the surface warm and cold fronts, daytime
highs on saturday should reach only the mid 50`s to mid 60`s in
nw pa and the 60`s to lower 70`s in northern oh. overnight lows
should then reach the upper 40`s to upper 50`s around daybreak
sunday. on sunday, peeks of sunshine and some daytime heating
should allow daytime highs to reach mainly the upper 60`s to
upper 70`s. weak and net low-level caa behind the cold front
should be accompanied by lows reaching mainly the 50`s around
daybreak monday. on memorial day, the aforementioned building
surface ridge will be accompanied by stabilizing subsidence and
clearing sky. despite the expectation for our area to be
located in the cool sector, sufficient sunshine and daytime
heating should allow highs to reach the mid 60`s to upper 70`s.
note: the coolest highs on sunday and monday are expected over
and within several miles of ~57f lake erie due to lake breeze
development during the late morning through early evening hours
of both days.
key message 2...
current odds favor drier and warmer weather this upcoming monday
night through friday since our region should become located
downstream of a pseudo rex block aloft that should become
focused over the central united states and vicinity. as a
result, the aforementioned surface ridge should continue to
affect our region and be accompanied by stabilizing subsidence
that strengthens with time, promoting clearer sky and greater
daytime heating. daily lows should reach mainly the 50`s or 60`s
around daybreak on tuesday through friday, while daily
afternoon highs should reach mainly the 70`s or 80`s.

expect deteriorating flight conditions over the next few hours
down into the ifr range as a shield of rain spreads northward
due to an area of low pressure moving into the region. the bulk
of the forecast is for both ceiling and visibility ifr in
prolonged, or at least periodic rain for the area. winds become
southeast over the forecast period gusting 20-30kts. these
winds should keep ceilings from reaching lifr as the lowest
levels of the atmosphere remain stirred up.
outlook...non-vfr expected into late saturday evening, and then
again late sunday into early monday.

.marine...
small craft advisory continues for the lake through late evening,
and then for the western basin through saturday morning as easterly
winds 20-30kts persist with wave heights generally 3-5ft. winds
continue out of the southeast saturday at 20-25kts, and wave heights
1-2ft in the nearshore zones, and 2-5ft in the open waters away from
shore. low pressure moves through, quickly followed by high
pressure, and winds become light and variable for sunday through
tuesday with wave heights less than a foot.

- rain overspreads the area from south to north tonight, then
tapers off from west to east on saturday. locally heavy
rainfall (1" plus), mainly for portions of northwest ohio.
- another system moves through on sunday with a chance for
showers (50-70%) and isolated storms
- warmer and mainly dry next week.

a period of enhanced moisture transport/convergence associated with
a northward advancing shortwave and weak sfc reflection will allow
rain to spread north over the area tonight into early saturday
morning. greatest chances (>60% per href) for locally heavier
rainfall totals in excess of an inch clip portions of northwest oh
where a strengthening low level jet draws in deeper moisture. up to
around a half inch expected elsewhere, save for far western in and
southwest mi where lighter rainfall is anticipated.
coverage of rain showers will diminish on saturday from west to
east, though some renewed development and perhaps a few storms will
be possible east of the interstate 69 corridor with the diurnal
cycle as some very weak destabilization occurs in the vicinity of a
trailing surface trough.
another shortwave and sfc trough looks to traverse the area on
sunday with renewed chances for showers and isolated storms, best
chances (50-70%) during the afternoon. coverage and rain amounts
should be more limited this go around however due to more nebulous
forcing.
a trend toward warmer, above normal, temperatures become the primary
story next week on the southeastern fringe of a developing upper
level ridge centered over the north-central us and south-central
canada. this should keep more humid conditions and better rain
chances locked up just south of the area near a stalled out
boundary. however, cannot rule out a few showers mid-late week as a
backdoor cold front potentially drops through (low confidence).

moisture continues to stream northward in conjunction with an area
of vorticity that passes overhead early saturday morning and moves
out of the area by saturday evening. rain is expected to pass
through the area as well with the heaviest rain moving through south
of us-24. lowered ceilings and times of lowered visibility will also
be possible as some of the lower levels of the atmosphere become
saturated with mvfr and ifr and possibly airport minimum conditions
on tap. as this area of forcing moves through, still expect
prevailing east winds until later tonight when winds gain a
northerly component. sustained winds between 10 and 20 kts will be
common with gusts between 20 and 30 kts. as the vorticity center
pulls away saturday, expect winds to begin to decrease as the
gradient decreases.

upper ridging and western extension of the canadian surface high
pressure will maintain dry conditions through remainder of the today
period. soundings showing some mixing into 25-30 knots within the
easterly low level flow through the afternoon, which should keep
gust potential to around 25 knots. increasing gradient flow into
this evening will allow for winds to remain elevated into tonight.
increasing gradient will be associated with a southern stream wave
and low pressure system lifting towards the ohio river valley out of
the ark-la-tex. this system is expected to bring the next round of
likely rainfall to southeast michigan ramping up towards midnight
and beyond with increasing isentropic ascent ahead of the surface
low. lack of instability and steep lapse rates will preclude mention
of thunderstorms for most of the area aside from the port huron to
monroe corridor. a favorable zone of 850-700mb fgen lifts across the
area tonight through tomorrow morning with pwats climbing to near or
around 1.50 inches. this will support a swath of higher localized
rainfall amounts exceeding an inch by the end of tomorrow, which is
also tied to the area of low thunder potential. there remains some
solutions with this higher swath holding just to the east in canada.
still a high chance for average amounts of 0.25 to 0.75 inches
across the cwa. the general track of the low targets still targets
the port huron to monroe corridor with higher end potential.
the surface low passes right through southeast michigan tomorrow
afternoon and evening. rainfall chances will gradually decrease with
its progression later in the day as best forcing is drawn northward.
winds will remain elevated through tomorrow afternoon until weaker
winds prevail and flow flips westerly in the wake of the low by
tomorrow night. there will a brief break in precipitation sunday
morning before rain chances increase again sunday afternoon as a
secondary wave and front move through. nbm temps on sunday likely
too high and probably more towards more normal values around 70
degrees given the rain chances, cloud cover, and weaker thermal
advection.
high pressure spreads across the region bringing a period of drier
weather early to mid week with a better signal for above normal
temperatures with upper 70s to low-mid 80s. troughing across eastern
canada during this time does offer some glancing shortwaves that
could produce some chances for rain. at this time, chances will be
low until there is higher confidence in timing and occurrence.

strong high pressure is building over eastern canada this evening as
low pressure lifts up from the ohio valley tonight. this will
further increase the easterly pressure gradient, allowing winds to
gust to 25 to 30 knots into saturday. small craft advisories are in
effect for all nearshore waters.
the low pressure system will also bring widespread rain showers and
a chance of thunderstorms to the central great lakes tonight and
saturday. the low will weaken and dissipate late saturday into
saturday night over lake huron, leading to lighter winds for the
second half of the weekend. however, another upper-level disturbance
will bring a good chance of showers and isolated thunderstorms over
lake erie and lake st. clair on sunday.
high pressure returns monday and slips east into the mid-atlantic
states on tuesday, maintaining generally light winds.
&&
.hydrology...
a round of steady soaking rainfall is forecast to spread across
southeast mi from south to north tomorrow morning as low pressure
lifts across the ohio valley and eventually through southeast
michigan. forecast rainfall totals range generally between a quarter
inch and three quarter inch during this event. locally higher
rainfall totals of an inch or greater are possible from monroe to
port huron. hourly rainfall rates on the order of a tenth to one
quarter of an inch per hour are expected. overall dry conditions for
much of the area over the past 30 days suggests the potential for
flooding is low, aside from typical isolated flood prone locations
in the urban areas.

area of low pressure lifting north through the ohio valley this
evening, will pass over the detroit area on saturday. this will lead
to deteriorating conditions tonight through saturday as the low
ushers a moist airmass into the region. vfr cigs today will fall to
mvfr tonight and ifr by morning. with the center of the low passing
through the first half of the day, low vsbys and cigs will linger
through the afternoon. showers will also accompany the low lifting
north through the area slowly overnight. a period of moderate rain
will be possible during the morning hours.
d21/dtw convection...no thunderstorms anticipated for the current
forecast period.
