Pittsburgh gets one more warm, mostly cloudy day Thursday before a stormy Friday ushers in a sharp cooldown. Morning temperatures are in the mid-50s, with the thermometer expected to reach about 72 degrees by afternoon. East winds around 6 mph should keep conditions fairly quiet through most of the day.
Showers Arrive Late Thursday
Most of Thursday should stay dry, but the rain chances rise after 10 p.m. Isolated showers could develop first, followed by scattered showers and thunderstorms between roughly 11 p.m. and 4 a.m. Friday, according to the National Weather Service.
Thursday night will remain mostly cloudy, with a low near 64 degrees and temperatures potentially climbing toward 70 overnight as warmer air moves in. South winds of 5 to 14 mph could gust as high as 26 mph.
Friday Brings Storms And A Sharp Cooldown
Friday is the roughest day in the forecast, with showers and thunderstorms likely and a 90% chance of precipitation. The high may reach 74 degrees early, but temperatures are expected to fall toward 61 by afternoon as west winds increase to 14 to 21 mph, with gusts up to 31 mph.
The weather service says parts of the region east of I-79 face a marginal risk for damaging wind gusts Friday. Severe weather potential appears limited overall, but stronger storms could still produce brief heavy rain and gusty winds.
Frost Follows The Weekend Cooldown
Showers remain likely Friday night as temperatures drop to around 42 degrees, with northwest gusts up to 26 mph. Saturday brings a much cooler high near 52, a slight chance of an early rain shower and mostly sunny skies later in the day.
Frost is possible after 2 a.m. Saturday night, when lows could fall to about 35 degrees. Sunday morning may start with more frost before sunshine takes over and temperatures rebound to around 60.
Sunny And Warmer Next Week
High pressure should bring a stretch of dry weather from Sunday through Wednesday. Afternoon highs are expected to climb from the upper 50s and low 60s Sunday and Monday to the mid-60s Tuesday and Wednesday.
For outdoor plans, Thursday afternoon offers the calmest window before the late-night rain arrives. Friday will call for extra caution around loose outdoor items and exposed areas, while the weekend will be better suited to jackets, warm drinks and frost-sensitive plants brought indoors.
