Although they lasted just a few minutes, we had some brief snow showers move through around 545 PM this evening.

We’re in for a change to winter-like temperatures by the end of the upcoming weekend. A wet and cool period is expected through Saturday. By Sunday night morning lows will drop below freezing with more sub freezing temperatures expected Monday night. Although a bit early to say…it does appear a warmup is in store for later next week.

We had our first frost overnight and early this morning. Not a hard frost, but more than just a few small patches. Last year our first frost occurred on Oct 28th.

The high temperature today reached 86°, which is about 20 degrees above the normal high for this time of year. A maximum of 86 would normally be expected in mid July.

We had a cold front move through early this morning. This is quite evident on the direction plot that shows wind direction over time. The dots in the center are oldest and ones near the outer edge are most recent. You can see the wind direction change from south to west after passage of the front. We also ended up with 0.86 inch of rain in the official manually read rain gauge compared with 0.75 in the automated gauge. The remainder of the week and into the weekend looks great with temperatures warming into the 70′s.
