Honestly, if you've ever spent a week in Shropshire, you know that a "weather forecast" is more of a polite suggestion than a rule of law. Shrewsbury is a bit of a weird one geographically. It’s tucked into a tight loop of the River Severn, which sounds romantic—and it is—until the sky turns that specific shade of bruised purple and the river starts eying the pavement.
Right now, it’s a standard January night. As of Sunday evening, it's about 40°F out there. Not freezing, but that damp, "gets-in-your-bones" kind of cold that 97% humidity provides. There’s a west wind, though it’s barely a breath at 0 mph. It’s cloudy, naturally. If you’re looking at the sky for a sign, don't bother; it's just a grey lid for the night.
The Microclimate Reality
Basically, Shrewsbury sits in a rain shadow. Because the Cambrian Mountains in Wales do the heavy lifting of soaking up the Atlantic's moisture, we often get a lighter version of the rain that hammers the coast. But there’s a trade-off.

The town is on a low-lying plain surrounded by hills. This creates a bit of a bowl effect. In the summer, it can turn into a heat trap—Shawbury, just up the road, has recorded temperatures hitting 34.9°C (roughly 95°F) in the past. In the winter? It turns into a frost pocket. The absolute minimum recorded in the area is a bone-chilling -25.2°C. That range is the largest of any individual station in the UK.
What to Expect This Week
You've probably noticed the light rain yesterday. That Sunday soak saw a high of 43°F and a low of 40°F. If you’re planning your week, here is the breakdown of what the weather forecast Shrewsbury UK is actually throwing at us.
Monday is looking mostly cloudy during the day, reaching a high of 46°F. Don't get too comfortable, though. By tonight, the chance of rain jumps to 65%.
Tuesday and Wednesday are where things get a bit messy. We’re looking at highs of 47°F both days, but the wind is going to pick up. Tuesday will see southeast gusts hitting 20 mph. It’s that annoying light rain that doesn't look like much on a radar but manages to soak through a "waterproof" jacket in ten minutes flat.
Thursday follows suit with more light rain and a slightly calmer 13 mph east wind. By Friday, the daytime stays around 46°F, but as the sun goes down, there's a 10% chance we might see a few flakes of snow as the temperature drops toward 39°F.
Why the Severn Matters
You can't talk about the weather here without talking about the river levels. The Welshbridge gauge is the one everyone watches. When the rain hits the Welsh mountains, it takes about 24 to 48 hours for that water to make its way down to us.
- Frankwell Car Park: Usually the first casualty. If the forecast says heavy rain in the Mid-Wales hills, move your car.
- The "Loop" Effect: Because the town is almost an island, once the Severn fills up, the Rea Brook (which meets it near English Bridge) often backs up too.
- Ground Saturation: With humidity sitting at 92% today, the ground is already like a sponge. Any extra rain this week isn't going to soak in; it’s going to run off.
The Long View: Heading Toward February
As we move into next week, things start to cool down. Sunday, January 25, will see highs of only 42°F. By Tuesday, January 27, the forecast is calling for snow showers during both the day and night.

Is it going to be a "Snowmageddon"? Kinda doubtful. The ground is too wet and the temperatures are hovering just above freezing at 33°F-40°F. It’ll likely be that slushy mess that makes the cobbles in the town centre a bit of a nightmare to walk on.
Honestly, the best way to handle Shrewsbury weather is layers. You’ve got to be prepared for it to be 47°F and windy one minute, then 40°F and drizzly the next.
If you're heading out, check the Environment Agency’s live river levels for Welshbridge. If the water is creeping toward the top of the "normal range" (which ends at 3.40m), it's time to start thinking about flood diversions.

Keep an eye on the wind direction too. That southeast wind coming in on Tuesday is going to make the 47°F feel a lot colder than it looks on paper. Grab the heavy coat, keep the boots by the door, and maybe skip the Frankwell car park for a few days.
