Pittsburgh residents can look forward to a break in wet weather and enjoy warmer temperatures as high pressure takes the lead in the weather narrative for the next couple of days, a bonus of calm before the return of rain midweek. The National Weather Service in Pittsburgh reports a dry and warmer day is on tap today with clear conditions anticipated this afternoon following a cloudy start, and these pleasant conditions are expected to persist through Tuesday.
Tuesday might not just be mild but could potentially rewrite the history books, with near-record temperatures predicted to lay challenge old high temperature marks in several areas including Zanesville, OH, New Philadelphia, OH, and Pittsburgh, PA; Zanesville set their previous record at 79°F in 2022, and 79°F for New Philadelphia and 80°F for Pittsburgh as far back as 1948. The forecast indicates anywhere between a 40-60% chance of the thermometer cresting 80 degrees, particularly south of I-70 as the high-pressure system continues its easterly march, which would result, and with more sun, wind gusts might ramp up with probabilities for gusts hitting over 30 miles per hour are 50-95%.
Weather shifts are on the horizon, however, with the National Weather Service anticipating a weak cold front moving through on Wednesday. Rainfall, needed in many areas, looks to be light and uncertain, dependent heavily on the play between systems over the Central United States, the intensity of Central CONUS ridging, versus an easterly wave that could potentially bolster precipitation totals. There is still considerable uncertainty in the forecast, making it unclear whether more significant rainfall or merely a light moistening is due.
In terms of aviation, pilots can expect generally favorable conditions at least over the next 24 hours courtesy of the high-pressure dominance, yet winds may pick up by late morning expecting to reach speeds of 7-12 knots with higher gusts up to 15-20 knots. Pilots should also be aware of low-level wind shear that may develop later tonight, affecting several airports during the overnight hours into early morning.The National Weather Service forecasts "low-level wind shear around 2000 feet with southwesterly wind around 35-40 knots" as high pressure continues its gentle path eastward.
No advisories are currently in place for Pennsylvania, Ohio, or West Virginia, maintaining the all-clear status for residents and travelers in these regions to enjoy unencumbered by immediate weather concerns, but as always, staying tuned to the latest forecasts is recommended as late-week conditions remain malleable and subject to change.
