Sleet — Weather Glossary
Precipitation consisting of a mixture of rain and snow, or partially melted snowflakes. It occurs when snow falls through a layer of above-freezing air before reaching the surface. Sleet is common in the UK during marginal winter conditions when temperatures hover near 0°C. A UK meteorological reference entry designed for clear forecast interpretation.

Sleet — Definition
Precipitation consisting of a mixture of rain and snow, or partially melted snowflakes. It occurs when snow falls through a layer of above-freezing air before reaching the surface. Sleet is common in the UK during marginal winter conditions when temperatures hover near 0°C.
A Closer Look
A compact way to interpret Sleet is to ask three questions: what is driving it, where is it most relevant, and what changes when it appears in a forecast?
- Driver: pressure, airmass, stability or upper-level support.
- Location: exposed coasts/hills versus sheltered inland spots.
- Outcome: cloud/visibility changes, rainfall organisation, or wind shifts.
UK Context and Forecasting Usage
Day-to-day UK weather often hinges on transitions: a front clearing east, a trough sharpening, or a wind direction shifting. Sleet is part of the vocabulary that makes those transitions explainable without drifting into vague phrasing.
This definition reflects the meaning we use consistently across England, Scotland, Wales and Northern Ireland.
We keep glossary definitions consistent across our UK pages to support clear comparisons between England, Scotland, Wales and Northern Ireland.
Where You’ll See It in Forecast Text
This term is often deployed in a ‘cause → effect’ structure: 'because Sleet applies, you can expect…' That keeps the wording concise without becoming vague.
- Typically appears once per section rather than repeated.
- Often paired with another concept (front, inversion, airmass).
- Used to make uncertainty explicit when it matters.
Practical Takeaways
This is the kind of term that becomes more useful once you connect it to a small habit: always check what else is mentioned with it.
- Pressure pattern explains a lot about wind and rain distribution.
- Wind direction often hints at the airmass source.
- Cloud type and visibility are often tied to low-level moisture and stability.
Clarifying Common Confusions
- Forecast language is designed to be consistent, not dramatic; the tone is intentional.
- A definition explains usage; it does not replace the day-specific forecast page.
- Two nearby places can legitimately see different outcomes under the same broad pattern.
Impact Awareness
This term can be linked to practical impacts, but the impact level depends on exposure and timing. In the UK, disruption often comes from short-lived peaks: stronger gusts near fronts, brief heavy downpours, or sudden visibility reductions.
Use the forecast page for day-specific detail; this note is here to keep interpretation grounded.
- In wind: gustiness matters most for travel and coastal exposure.
- In heavy showers: brief intensity can matter more than totals.
- In winter: marginal setups can vary sharply by elevation and time of day.
- In visibility: local fog can be highly variable under light winds.
