SYNOPSIS. Pre-frontal rain showers are expected later this afternoon. High pressure will keep the region dry during the late week. Rain will likely return this weekend.

NEAR TERM /THROUGH TONIGHT/. A shortwave with coincident surface low pressure is traversing the upper Great Lakes and will drag a cold front across the Ohio Valley late this afternoon. Most attendant forcing is displaced to the north in accordance with the shortwave, so main focus for rain showers will be coincident with forcing as a result of frontogenesis.

Some DCAPE is noted in western Ohio with the front. Warm and moist advection has occurred all morning so far, and may allow for lapse rates in the low levels to reach 6.5 C/KM. Rain showers will be progressive, but may be accompanied by gusty winds at times as a result of this instability and potential for winds to translate to the surface with proper mixing.

With any lingering showers over the WV Ridges, a transition to snow may be possible with frontal passage. Once the cold front passes late tonight, much colder temperature will be observed area-wide.

SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/. Seasonable temperature is expected Thursday, with building high pressure throughout the column. With passing upper level vorticity advection, clouds are likely to remain.

LONG TERM /FRIDAY THROUGH WEDNESDAY/. Warm and moist advection will return this weekend as another shortwave traverses the Great Lakes. This will bring the chance for above seasonable temperature, and precipitation in the form of rain.

AVIATION /18Z WEDNESDAY THROUGH MONDAY/. Expect cloud cover to be on the increase as a cold front approaches the region. Until then, expect VFR conditions to persist at least through 22Z in some places. Winds have mixed to the surface with the LLWS threat ending. Still, southwest winds will gust up to 25 knots through the afternoon and some isolated spots even higher. This will be followed by showers developing into the area with MVFR and even some IFR cigs developing later this evening. Behind the front, a layer of stratocumulus will create some cigs tonight last through the bulk of the TAF period. Expect winds to decouple by midnight if not a couple of hours earlier.

Outlook. VFR conditions will return on Thursday with building high pressure.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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.
