Humidity, storms will return on Sunday

It has been quite a stretch of pleasant weather. In fact, stretches of low humidity weather with sunshine and warm temperatures like we just experienced are quite uncommon during this time of year. The good news? This stretch isn’t quite over yet. The pleasant and low humidity weather will continue through Friday evening and into Saturday, as high pressure remains in control. Mid level temperatures, however, will slowly warm up over the next few days.

By Sunday, the atmosphere will become increasingly perturbed. By Sunday afternoon, instability will begin to build as a weak trough and disturbance approach the area. And with that, will come a break in the stretch of pleasant and dry weather. Although shear remains weak for storm organization, pulse thunderstorms, some strong, appear likely on Sunday afternoon. Some of these could contain heavy rain and frequent lightning.

By early next week, the pattern will be undergoing more typical summer-like changes. Showers and thunderstorms, some strong, will be possible each day. And each day, the ridge will build toward our area as it collapses over the Central United States and shifts northeast. Mid level temperatures will warm up dramatically by Tuesday, Wednesday, and Thursday.

In fact, by Thursday, many forecast models indicate the potential for one of the hottest days of the season thus far. 850mb temperatures over 20 C would support mid to upper 90 degree temperatures if the sun can stay out during the majority of the day. This hot weather will, of course, be followed by a continued chance for showers and storms.

For now, however, enjoy the pleasant and wildly comfortable weather — with cool temperatures at night and just-perfectly-warm temperatures during the day.
