A spring-like week with storm chances, then turning cooler

Humidity and warmth could lead to storms this week

FORECAST HIGHLIGHTS

  • STRAY STORMS TUE/WED: Most will stay dry, but we’ll watch for a pop-up or two
  • BETTER STORM CHANCES BY FRI: Shower/storm chances increase
  • OAK SEASON IN FULL SWING: Expect numbers to stay high
  • COOLER: Mornings in the 40s and afternoons in the 60s Sunday through Tuesday

FORECAST

WEAK FRONT TODAY

The storm threat is done for the evening, and the rest of the night will be quiet with a clearing sky and temperature falling into the 60s by sunrise.

STRAY STORM TUESDAY AND WEDNESDAY

As humidity surges back into the area tomorrow, morning clouds will develop and likely hang around a while. A few very light showers or sprinkles may also show up. Should we get some sun in the afternoon, there’s a very small chance of a storm. A strong lid on the atmosphere likely keeps storms out of the picture, but it’s worth a mention, because any storm that does develop would become severe. This will also be the case on Wednesday.

BETTER ODDS FOR RAIN LATE IN THE WEEK/SATURDAY

The upper level pattern will become even more active by Thursday and more so Friday and Saturday. We’ll keep the ongoing morning clouds/afternoon sun forecast going. Then, Thursday afternoon, isolated storms will be possible. The odds of showers and storms increase late Friday into Saturday morning. Severe weather would be possible, if storms do indeed develop. This has the potential to affect Final Four weekend, so you’ll want to check back with us. A front arrives by Sunday, cooling us down and bringing an end to rain chances.

OAK SEASON RAMPING UP

Oak numbers have been increasing, as trees look primed to spread pollen. This will last for another month or so, with peak numbers likely showing up over the next few weeks. Your car may develop yellowish/greenish tint... at least for a while!
