SYNOPSIS. High pressure will maintain dry weather for the area through tomorrow night with well-above average temperature. Rain chances return early Thursday morning as a low pressure systems tracks north.
NEAR TERM /THROUGH WEDNESDAY/.
High pressure will maintain dry, warm conditions overnight and into tomorrow. A slight chance of patchy fog may be observed early tomorrow morning in Garrett County as low temperatures approach the crossover temp. Otherwise, high and mid- level clouds will gradually build south to north as moisture associated with a tropical disturbance off the coast of the Carolinas tracks north.
SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/.
By Wednesday night, the disturbance mentioned above will become an open wave and continue its northward track into the Upper Ohio Valley. Light stratiform precipitation (perhaps initially broken as the mid- level dry air saturates) will overspread northern WV after midnight and slowly lift northward through the morning along the convergent axis on which it's centered.
A deepening trough over the Great Plains will help maintain quick northern progression of the wave through our region early Thursday morning, thus drier conditions in wake of this trough should be observed mid-afternoon and flooding concerns should be low. With models promoting strong ascent (850mb winds near 40kts) and PWATs near 1.80 to 1.90, a swath of 1.00 to 1.50 inches may accumulate in portions of our area.
Scattered, diurnally-driven showers or even a tstorm Thursday evening may develop despite lack of upper forcing or strong buoyancy in the mid- levels. Coverage will ultimately depend on how fast that trough and associated cloud cover move out. The quicker the sun returns, the more instability and shower/tstorm coverage we can achieve Conversely, if cloud cover lingers around longer. the latter half of Thursday may remain dry with slightly cooler temperature.
LONG TERM /FRIDAY THROUGH TUESDAY/. Pattern flip alert. By Friday morning, northern stream troughing will dig into the Great Lakes region and help kick the meandering aforementioned mid-south low eastward into the Atlantic. An attendant cold front will stretch from the surface low in the Ontario/Quebec region southwest into the Ohio Valley. While some precipitation may occur before the frontal rainband given the warm, moist air, the bulk of the precipitation on Friday will occur late afternoon and into the evening hours near/along the frontal zone itself as it moves across the forecast area. The strongest areas of synoptic lift will be displaced closer to the vort maxima of the northern and southern stream troughs, with Pittsburgh in between these. As a result, this front doesn't look to be a big rain-maker at this time. A marginally unstable environment may be just conducive enough for a couple embedded thunderstorms and heavier rain rates-- but nothing appears rather eye-catching at this time.
Precipitation should be clear of the forecast area by daybreak Saturday as comparatively cooler, drier air filters in behind the front.
Each day from Saturday through Tuesday appear to be either near or below-average as far as temperature-- or about 15(or more!) degrees cooler than what we've experience this week. No major precipitating-features seem to be present in the pattern, though cannot rule out some light showers in this stretch as any pronounced shortwave troughing rounding the base of the longwave trough could produce something light.
Confidence in this extended period is greater than usual given run- to-run consistency and agreement in the models.
AVIATION /02Z WEDNESDAY THROUGH SUNDAY/. VFR conditions to remain in place across the area through the TAF period as high pressure will remain the dominant weather feature.
Outlook. No widespread restrictions are expected until Thursday as the next frontal system approaches.

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.
