Cool now, summer later: Memorial Day warmth on the way

Monthly Recap:

May has delivered a mixed bag in the Stateline so far, with a noticeable tug-of-war between spring chill and early-summer warmth. Out of the first 20 days of the month, we've logged only 4 days stuck in the 50s and five days stick in the 60s, highlighting some of those cooler, cloudier stretches. But warmer air has made its presence known - 11 days have climbed above the 70-degree mark, giving the month a mild and at times summer-like feel despite those dips. 

Cooler Stretch Continues:

Looking ahead, it looks like those occasional dips will win out prior to Memorial Day as cloud cover works its way back into the Stateline. We'll especially notice that on Friday with thicker clouds limiting sunshine and keeping temperatures in check. Afternoon highs will hold in the low to mid 60s. Winds will also have a say as they will be out of the east-northeast today, then out of the east on Friday. 

Holiday Weekend Surge:

Fortunately, a much warmer pattern sets up for the holiday weekend. Temperatures will surge thanks to a strengthening ridge of high pressure building in aloft in the atmosphere. This displaces the jet stream far to the north, placing it across southern Canada. 

This type of setup will promote more sunshine as well as a steady warm-up, allowing afternoon highs to climb back into the 70s this weekend, and even the low 80s for Memorial Day and next week. Along with this ridge comes limited rain chances and extremely low severe weather potential.
