A temperature roller coaster is in store this week

FORECAST HIGHLIGHTS

  • COOL THROUGH TUESDAY: In the short-term, we’ll stay cloudy and relatively cool (50s and 60s)
  • HOT WEDNESDAY: Temps rebound in a big way on Wednesday (upper-70s)
  • COLD THURSDAY: A cold front will knock down temps yet again (40s and 50s)
  • ROUND TWO THIS WEEKEND: Cool Friday, noticeably warmer Saturday, then cool again Sunday

FORECAST

We’ll visit all four seasons this week! Depending on the day, we could see vastly different weather, so know that this forecast will keep you on your toes. Let’s start with today:

MONDAY (COOL)

Expect fairly steady temps today. We’ll stay in the mid-to-upper 50s for most of the day while clouds hold. You’ll want at least a light jacket and know that a few sprinkles or a stray shower will be possible.

TUESDAY (MILD)

Tuesday’s forecast is a bit more tricky, as it all hinges on the location of a warm front. In these situations, the cool air is often hard to dislodge, so for now, we are calling for another cool day. Highs will remain in the 50s and 60s, with overcast skies. Patchy morning fog is possible along with some spotty showers, but any rain found should be relatively light in nature. That could change for some of us Tuesday night where our best chance (40%) for showers and even a few storms resides.

WEDNESDAY (WARM)

As dry air and sunshine quickly return by Wednesday afternoon, temperatures are forecast to soar to near 80 degrees. This is likely one of the warmest days in our extended forecast. It’s short-lived, though, because a strong cold front will arrive Wednesday night.

THURSDAY (COLD)

That warmth described above will be quickly erased by the front. In fact, we’ll dip into the low-40s, with wind chill values in the 30s Thursday morning. Additionally, we’ll struggle to warm out of the 40s Thursday afternoon. Expect a mostly cloudy day.

VALETINE’S DAY (MILD)

After a cold start (mid-30s), temperatures on Friday will reach for the upper 50s and low 60s.

WEEKEND (WARM SATURDAY, CHILLY SUNDAY)

Another cold front will bring us more variable weather this weekend. Stay tuned for updates!
