You've probably heard the jokes about Texas weather. If you don't like it, just wait five minutes, right? In Mount Pleasant, that’s not just a cliché; it’s a lifestyle. Located up in the piney woods of Northeast Texas, the weather mt pleasant tx 75455 can be a bit of a wildcard, and honestly, the generic forecast apps often miss the nuance of what it actually feels like on the ground here in Titus County.
Whether you're planning a trip to Lake Bob Sandlin or you just moved into a house near Dellwood Park, understanding the local atmosphere is key. It’s not just about the temperature. It’s about the humidity that sticks to your skin in August and the biting "blue northers" that can drop the mercury 30 degrees in a single afternoon.
The Reality of Winter in the 75455
Right now, as we move through January 2026, we’re seeing a classic East Texas winter. Today, January 12, started off with a low of 28°F, but it's aiming for a high of 60°F. That's a massive swing. You leave the house in a heavy parka and by lunch you're throwing it in the backseat of your truck.
Looking at the upcoming week, we’ve got highs reaching into the upper 60s tomorrow, followed by a sharp dip back to the 50s. Most people think "Texas" means "Hot," but Mount Pleasant gets cold. Real cold. The record low for the area is a bone-chilling -12°F. While that’s rare, seeing nights in the 20s is perfectly normal.
Does it actually snow here?
Sorta. We average about 1.9 inches of snow a year. It’s usually that wet, slushy stuff that disappears by noon, but every few years, we get a real "ice-pocalypse" that shuts down I-30. If you see a forecast for freezing rain, take it seriously. Titus County isn't exactly equipped with a fleet of snowplows, so the bridges become skating rinks pretty fast.

Spring: The Most Beautiful (and Dangerous) Season
Spring is arguably the best time to be in Mount Pleasant. The dogwoods start blooming, and the temperatures sit in that "sweet spot" of 65°F to 75°F. It's gorgeous. Honestly, there's nothing like it.

- Hail: Don't be surprised to see marble-sized (or larger) hail during a heavy cell.

- Monitor the Mount Pleasant Regional Airport (KOSA) Station: This is the most accurate data for the 75455 area. It provides real-time updates on wind gusts and dew points that generic "city-wide" forecasts might miss.
- Landscape for Drainage: Given the severe flood risk in certain parts of town, ensure your gutters are clear and your property drains away from the foundation before the spring rains hit in March.
