.SYNOPSIS...
The area will remain on the warm side of a stalled front over the
central Great Lakes region through tonight. This front will get
pushed southeast on Tuesday and stall over the local area Tuesday
night into Wednesday. Low pressure will move northeast along this
front on Wednesday into Thursday and the front will exit east by
Friday.
&&
.NEAR TERM /THROUGH TUESDAY NIGHT/...
The main concern in the near term will be a line of showers with
some thunderstorms moving through the eastern half of the
forecast area. The air mass ahead of this line has been
marginally conducive for strengthening storms with ample
clearing across the region this afternoon, allowing for a
slightly more conditionally unstable air mass. In addition,
there is a slight increase in low- and mid-level winds with a
shortwave moving through the region, which has allowed for the
shear to increase. Will continue to monitor this line of
convection for stronger cores and cell mergers which could allow
for some strong to severe wind gusts or some marginal hail.
However, the remaining area that is vulnerable is shrinking
quickly with this line of convection overtaking the region.
Behind the main line of convection, light stratiform rain is
overtaking the region. The axis of this rain will slowly shift
east through the evening into tonight with the focus eventually
over the eastern portion of the forecast area. Northwest Ohio
has a chance to dry out late tonight into Tuesday; however,
ample low level moisture will allow for widespread low stratus
and fog to form, which may pose a hazard to the Tuesday morning
commute. For Tuesday, the main area of stratiform rain will push
east with the mid-level shortwave and the area will be south of
the upper low over the upper Great Lakes, which means that there
will be a minimum in forcing for additional rain. Cannot rule
out rain or even a storm lingering in the region or firing off
a lake boundary, but the trends in rain are down and have mostly
20-30% PoPs by afternoon.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
The short term forecast period will feature multiple additional
rounds of rainfall for the area, as a low pressure system lifts
northeast along the stalled frontal boundary with support from a
closed upper low over the Great Lakes region. Wednesday should
feature a widespread round of rainfall and some possible
embedded thunderstorms as a shortwave ripples around the upper
low and over the area. Total rainfall across the region on
Wednesday continues to trend higher with most areas likely
receiving 0.50-1.00" of rain with efficient rainfall. For
Thursday, the upper low over the Great Lakes will open up into a
trough and progress eastward through the eastern Lakes and Ohio
Valley. This trough will support pushing the front east as a
cold front and allow for another round of scattered showers and
some potential thunderstorms. Given coverage concerns, will have
PoPs slightly lower on Thursday, as compared to Wednesday, but
should still be in the likely category for the eastern half of
the area. Temperatures will be generally seasonable with highs in
the low-to-mid 70s although repeated rounds of precipitation may
keep the general flavor of temperatures in the 60s.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
For Friday, the upper trough axis will continue to swing through
the forecast area and may allow for some showers to still be in
the region until it exits. For the weekend into Monday, the
trend is dry with the next system missing the area to the north
and high pressure moving over the local area. Temperatures will
still be seasonable in the 70s with the air mass behind the
mid-week front and upper trough only marginally cooler and
quickly recovering for the weekend.
&&
.AVIATION /18Z Monday THROUGH Saturday/...
Widespread showers and thunderstorms are moving across the region
this afternoon into the evening. Generally, most terminals are still
VFR, though within the showers, visibilites and ceilings have been
dropping to MVFR/IFR. Confidence is low for thunderstorms over
terminals, but those with the best chances will be KMFD, KCAK, and
KYNG from now through 23Z, with some lingering thunder in the most
eastern portion. As showers move out to the east, fog potential will
increase into the morning hours tomorrow. Guidance has been
increasing in widespread fog, especially across the western
terminals from 05-14Z. To the east, with showers still continuing
into tomorrow morning, fog chances will be lower. Though,
visibilities and ceilings will still drop down to IFR conditions
with the lower levels being saturated. Visibilities should start to
increase after 14Z tomorrow, but there may still be some lingering
spots. Ceilings will be slower to rise, so expect non-VFR ceilings
through the morning tomorrow.
Winds will generally be out of the south at 5-10 knots through the
TAF period. Within showers and thunderstorms gusts around 20 knots
can be expected.
Outlook...Non-VFR conditions possible through Friday with
scattered showers and thunderstorms.
&&
.MARINE...
Conditions across Lake Erie will be fairly quiet through this week,
though showers and thunderstorms could be locally higher winds and
waves.
Winds will predominately out of the southwest at 10-15 knots today
and Tuesday then becoming southeasterly at 5-10 knots by late
Tuesday night. By late Wednesday night winds will shift to be more
easterly and increase to 10-15 knots across the lake. A low pressure
system will move across the region late Wednesday into early
Thursday and winds will shift to be out of the northwest throughout
the day Thursday behind the passing cold front. High pressure will
begin to build into the region moving into the weekend and winds
will become lighter, generally less than 10 knots and out of the
southwest.
