Pittsburgh residents can expect a reprieve from gusty winds this morning and a return to seasonable autumn temperatures. According to an early forecast by the National Weather Service in Pittsburgh, the Wind Advisory that was in place for eastern Tucker County, WV has expired as of 8 am. The region, recovering from the rains brought on by a cold front, saw rainfall rates of 0.10 to 0.15 inches per hour, with additional rainfall of up to 0.40 inches expected.
In the wake of the front, Pittsburghers will experience cooler air, with today's temperatures trending slightly below average. Winds were reaching 25 to 30mph in lower areas, and even 40-50mph along the ridges, but they will ease as the morning progresses. Wind gusts are expected to ease by mid-morning as the pressure gradient weakens with the departure of the low-pressure system, reported the National Weather Service. As the day unfolds, the likelihood of showers decreases, and a ridge building to the west should bring about clearer skies.
Looking ahead, the forecast for Monday evening is promising a calm and clear night. Overnight low temperatures could dip into the mid-30s, though no frost advisories have been issued due to higher dew points lingering in the mid to upper 30s. Tuesday might see an increase in light rain chances with the passage of a warm front, but any showers are expected to be brief and yield less than a quarter-inch of rain.
From Tuesday night through the week's end, shortwave troughs moving through areas around the Great Lakes are likely to cause isolated to scattered showers, with the potential for gusty downdrafts. High-resolution guidance indicates that a shortwave embedded within a broader Great Lakes trough will bring another round of showers late Tuesday evening into early Wednesday, the Weather Service noted. Temperatures during this time frame are predicted to trend below average by about 10 degrees, and late in the week, residents could be looking at frost or freeze conditions once again.
For aviators, VFR conditions are expected throughout the area by late morning thanks to a shift in low-level flow and increasing drier air. Winds will continue to gust between 20 to 25 knots throughout the day, diminishing in the evening. The high-pressure system moving through should maintain stable conditions through Tuesday, with possible weather-induced restrictions arising mid-week as the forecasted troughs make their way across Pittsburgh.
