Texas is in for another winter shake-up — and San Antonio is right in the middle of it. The calendar says December, which means we’ve stepped into what meteorologists officially call Meteorological Winter — the three-month stretch from December through February used for climate studies. It lines up perfectly with how the weather’s been behaving. After all, Monday’s chill probably had you humming the holiday classic that reminds us that sometimes “the weather outside is frightful.”
Only days ago, the state went from balmy weekend warmth to the season’s coldest plunge. And here’s the kicker — forecasters say it’s just the beginning of a busy December ahead. According to the latest long-range forecast from the Climate Prediction Center, Texas can expect conditions to be slightly warmer and wetter than average this month. That might sound pleasant, but it also sets the stage for some unpredictable twists in the weeks ahead.
On Tuesday morning, San Antonio will start the day under mostly clear skies, waking up to brisk mid-30s temperatures — a solid 5 to 10 degrees below the city’s usual highs and lows of 67 and 45 degrees. A ridge of high pressure will dominate, keeping skies bright with gentle north winds and crisp winter sunshine.
But don’t pack away that jacket just yet. Tuesday night will stay chilly, although shifting winds from the south will slowly introduce a touch of warmth. Overnight lows will hold steady between 37 and 42 degrees. By Wednesday, the city should feel a bit more comfortable as highs climb back into the mid- to upper-60s, making it the warmest day of the workweek.
Then comes the next twist. A new storm system will sweep across South Texas midweek, ramping up rain chances from Wednesday through Friday. This front might not have the same bite as last weekend’s, but it will help lock in that classic fall-like coolness while delivering a dose of much-needed rain. Bexar County remains under severe to extreme drought conditions, trailing about four inches below normal rainfall for the year — so even a few steady showers could make a real difference.
Here’s where it gets tricky — and where meteorologists tend to disagree. The storm system’s path and rainfall potential depend on several moving parts. If the front speeds up, rain may taper off quickly. But if a lingering low-pressure area over the Pacific gets pulled into the system, the region could experience longer-lasting, heavier rainfall. Essentially, it’s a timing game that could swing either way.
For now, forecasters are cautiously optimistic, calling for moderate rain chances — roughly 30 to 60 percent — across South-Central Texas on Thursday and Friday, with higher odds closer to the coast. Totals by Saturday morning could reach about half an inch along the I-35 corridor, while coastal areas might soak up four or more inches.
But here’s where opinions may split: Is a warmer and wetter December really good news for drought recovery, or could it signal more unpredictable winter weather ahead? San Antonio residents have seen their fair share of wild swings this year — from heat waves to flash floods — so it’s worth asking: would you rather have a mild, soggy winter or a cold, dry one? Drop your thoughts below — this winter forecast might spark more debate than you think.
