Synopsis
A cold will bring rain to the area on Thursday and early Friday.

Cooler, drier air will then return for the weekend.

Near term until 6 am Thursday morning
A few showers have developed across the region with the presence
of some low to mid-level instability and passage of a weak, subtle
shortwave. Have backed off pops from the earlier forecast as the
stratodeck has kept heating to a minimum. This and substantial warm
air aloft, as observed in the 12z pbz and local amdar soundings,
will inhibit updraft growth.

The overnight period will be quiet in terms of weather. Any daytime
shower activity will diminish after sunset. With warm, humid air in
place and cloud cover, temperatures will remain warm. Lows will range
from the mid 60s to around 70.

Short term 6 am Thursday morning through Friday
Shortwaves rotating around a deep upper low over james bay will
result in a cold front dropping southward to near the erie lakeshore
by Thursday morning, where it will then become nearly stationary
under quasi-zonal flow.

Convection will develop south and in the vicinity of the cold front
on Thursday as mid-level impulses traverse the zonal-to-southwest
flow. Moderate instability (mlcape 500-1250 j kg) south of the i-80
corridor and modest 0-6km bulk shear may allow for a few organized
storm clusters, with greater potential farther south. Additionally,
warm cloud depths and mean cloud layer wind nearly parallel to the
frontal boundary may lead to a marginal flash flood threat in any
training convective segments.

The cold front will push southward through the CWA Thursday evening
and overnight, with showers ending from north to south overnight as
drier air filters in.

A few showers or possibly even a thunderstorm may initiate on
Friday, primarily south of the mason-dixon, in close proximity to
the mid-level frontal boundary. Temperatures will be near or just
below seasonal, with highs in the 70s on Friday.

Long term Friday night through Wednesday
Dry conditions with seasonal temperatures are expected to prevail
this weekend under northwest flow aloft. Highs over the weekend will
be in the 70s and lower 80s, with lows generally in the 50s.

Return flow will commence at the start of next work week as the
ridge axis slides eastward. This will bring a return of warmer, more
humid air into the region. Precipitation chances return as a low
moves up from the deep south.

Aviation 20z Wednesday through Monday
Cu CIGS will slowly lift through this afternoon due to diurnal
heating and lift provided by a 700mb shortwave trough. Iso sct
showers will develop with this increased lift given the moist
environment, but a strong cap of warm air at 550mb will limit
updraft heights into the hgz. This should squelch lightning
generation, meaning only showers will be possible thru this evening.

Showers will be brief, but may cause short periods of cig vis
restrictions.

MVFR ifr CIGS with patchy fog will develop overnight as boundary
layer moisture remains trapped underneath a low level inversion. A
storm complex will move up the oh river valley Thursday morning and
bring showers to the region, which will either enhance the low
stratus decks, or provide enough lift at least raise CIGS a category
or two. Confidence is low for this given the dependency on the
evolution of the storm complex.

Outlook
Periodic restrictions will continue through Friday morning until a
well-defined cold front moves through the region.VFR dry weather
conditions will return this weekend.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
