This post distills the day-to-night weather forecast for New Castle, Pennsylvania (ZIP code 16105) into an accessible, science-informed summary.
Drawing on three decades of meteorological experience, I explain the expected cloud trends, temperature range, wind behavior, and precipitation probabilities. I offer practical advice for residents and planners who need to make decisions based on a forecast that includes some uncertainty.
Short-term outlook for New Castle, PA
The forecast through tonight calls for a transition from a partly sunny morning to mostly cloudy conditions by the afternoon. There is a modest chance of daytime showers.
This pattern is driven by a west-southwest flow bringing relatively mild air. A weak disturbance could trigger scattered rainfall.
Temperatures are expected to peak near 74°F in the afternoon. They will then fall to around 50°F overnight.
Wind shifts and cloud cover during the evening will influence how quickly temperatures drop. They will also affect where showers develop.
Key meteorological details
Below are the most relevant elements of the forecast presented in concise, actionable terms for residents, event planners, and local responders.
Interpreting the 40% chance of rain
A 40 percent probability does not mean it will rain for 40 percent of the time; it means there’s a 40 percent chance that measurable precipitation will occur at any given point in the forecast area.
For communities like New Castle, that equates to a realistic possibility of scattered showers, especially during the evening hours when atmospheric lifting and moisture converge.
Given the southeast-to-southwest wind pattern earlier in the day holding at around 10–15 mph, showers that form can move quickly and be transient.
Expect variable conditions rather than steady, prolonged rainfall.
Practical recommendations
For most residents, this is a moderate-impact forecast.
Here are simple steps to stay prepared and comfortable:
New Castle can expect a mild afternoon with increasing cloud cover. There is a modest chance of daytime showers and a greater likelihood of evening rain before clouds persist overnight.
