As Pittsburgh eases into November with a touch of autumn's capriciousness, the National Weather Service Pittsburgh PA has issued a weekend weather synopsis indicating mostly dry conditions with a slight chance for light showers. According to their forecast, weak ridging and high pressure will keep the steel city mostly shielded from the rain, leaving just a 20-30 percent likelihood for those living north of I-80 to see lake-effect showers before evening.
The storyline changes slightly tonight, where an upper low brings a promise, albeit a slender one, of a few light showers to those dwelling south of Pittsburgh. The National Weather Service detailed the discussion notes a 10-20% chance of measurable precipitation, particularly around the West Virginia ridges, whilst acknowledging the possibility of increased cloudiness. This could lead to slightly warmer overnight lows.
Moving into Sunday and Monday, things are expected to stay relatively calm. A slight chance for showers persists to the south of Pittsburgh on Sunday, and to the north on Monday, as disturbances skirt by the region. The forecast discussion anticipates the reappearance of dry weather across the board as lake-effect showers recede and the passing upper low moves out.
Looking ahead into the week, a semblance of routine emerges with periodic precipitation chances and seasonably average temperatures. Another upper shortwave trough making its way across the region could spell brief rain showers from Wednesday into Thursday, particularly northeast of Pittsburgh. Despite these transient disturbances, temperature readings are predicted to hover near or a tad above the seasonal average, as none of the weather systems in play are of significant strength to cause any drastic fluctuations.
In terms of aviation weather, VFR conditions are highly probable during the TAF period, offering clear skies for takeoffs and landings. Pilots, however, should be aware of gusty winds through the afternoon, which are expected to subside come nighttime. Subsequent weather patterns involving shortwave troughs on Monday and Tuesday might create low probabilities for rain, but VFR will likely be restored shortly thereafter.
No watches, warnings, or advisories are currently in effect, allowing Pittsburgh to enjoy a relatively undisturbed seasonal serenade before winter begins its annual, more assertive composition.
