Pennsylvania – Headlights cut through dense fog and mist this morning in Pittsburgh, where visibility drops near four miles and damp roads already slow early traffic.
According to the National Weather Service, clouds break through the morning, allowing temperatures to surge to near 63°F today, then spike to an unseasonably warm 78°F by Sunday afternoon. That rapid warm-up sets the stage for an active weather shift.
Showers develop after 2 p.m. Sunday, then intensify into the evening with a 60 to 90 percent chance of rain and thunderstorms. Rainfall totals could reach up to three-quarters of an inch, especially in heavier bursts. Roads like I-376, I-79, and Route 28 may become slick quickly. Plan extra travel time Sunday evening.
Meteorologists now tracking this system say conditions may deteriorate quickly after sunset, with steady rain and isolated thunder continuing into early Monday. Visibility may drop below a mile during heavier downpours.
By Monday morning, lingering showers taper off, but cooler air moves in fast. Highs fall to around 48°F, and skies begin to clear later in the day.
That cooldown sharpens by early Tuesday, with lows dipping to near 27°F. Any leftover moisture could refreeze, creating black ice on bridges and untreated roads. The morning commute Tuesday may be slick despite dry skies.
Sunshine returns Tuesday with highs near 54°F, followed by a gradual warming trend into midweek.
This pattern highlights a classic March swing—warmth, storms, then a quick return to cold.
