Get ready, Pittsburgh, it's time to crank up the AC and brace for a heatwave. The latest from the National Weather Service outlines an incoming hot and humid trajectory through the weekend. Today, you can expect clear skies with dry conditions, setting the stage for a gradual climb in both mercury levels and sweat beads.
Witness the southward shift, as the winds influence our weather narrative, driving up temperatures and nudging dew points to follow suit, as reported by the National Weather Service. They're predicting, everyone, whether you live south of I-80 or you're navigating the urban heat islands, to get their fair share of upper 80 to 90 degrees Fahrenheit fun.
By Thursday, thermometers are expected to remain stubbornly in the lower 90s for most areas, except those fortunate enough to reside at higher altitudes. This heat rage comes courtesy of a 500mb ridge and southerly winds determined to reinforce the summer sizzle, so mid to upper 90s heat index values are on the menu, and yes, some spots are gunning for the century mark. Friday ushers in a shift, with showers and thunderstorms potentially gatecrashing our sweat party, as noted in the NWS bulletin, which forecasts increasing clouds and possibly severe weather, although shear will be "marginal."
Into the weekend, the odds for periods of rain and thunderstorms remain as high as the humidity levels, stretching until Tuesday with brief respites possibly on Monday. As the surface boundary stubbornly persists, the NWS advises that we could witness a rinse-and-repeat pattern of afternoon and evening showers and thunderstorms. Daytime heat relief may seem as fleeting as the reprieve between cloud bursts.
Aviators can take solace, according to the NWS discussion, with clear VFR conditions anticipated through early Thursday, allowing those airplanes to taxi unfazed by the weather below. However, from Friday to Sunday, as the forecast indicates grey skies and potential visibility challenges, pilots should remain vigilant for rain and possible restrictions.
