Pittsburgh residents can look forward to putting away their umbrellas this weekend, as the latest forecast predicts a break from the recent stretch of rain. According to the National Weather Service in Pittsburgh, PA, the city is expected to experience "scattered showers continue on Wednesday before drier air works in for the weekend and into next week," suggesting that as we head towards the weekend, the weather will be on an upturn, with temperatures warming up to above the norm.
Today, we will see the departure of an upper atmospheric trough to the southeast. As surface high-pressure inches from the west, we're looking at a break in the rain soon after sunset and a likely cold night with "another night of frost/freeze concerns Wednesday night," as cited in the National Weather Service discussion. Despite the chill, those bundling up today can look forward to a dry and warmer trend kicking off tomorrow; however, continue exercising caution as temperatures are set to drop again Thursday night, potentially leading to the coldest evening yet this week, with high probabilities for sub-freezing conditions extending through the rural expanses.
Moving into the short term, a distinct warming pattern is set to phase in, coupled with dry conditions making a comeback, while frost advisories may extend into Thursday night. The gradual warming trend with a sunny disposition is forecasted to bring a pleasing change by week's end. The National Weather Service speculates that residents can expect a "return to the mid 60s come Friday under high pressure as the upper ridge axis establishes overhead," indicating that those weekend plans could include enjoyable outdoor activities under the sun.
The long-term outlook remains favorable, with dry skies and temperatures on the favorable side of chilly expected to persist. High pressure is projected to prop up, cultivating a scenario optimal for outdoor ventures and keeping precipitation at bay well into the following week. However, in a testament to the fluctuating nature of fall weather, ensemble solutions show a split on how a moving wave across the country might affect our temperatures midweek.
