It was hot couple of days in Western Wisconsin. That came to a crashing end today as a cold front pushed through Western Wisconsin. More on that in a bit. Let's first talk about our first 90s of the season!
Our summer preview began on Friday with Eau Claire topping out at 91 degrees for the first 90 degree day since September 1st. La Crosse was just shy of 90 degrees, but the next day both Eau Claire and La Crosse hit 91 degrees.
On average, the first 90 degree of the season occurs on June 11th in La Crosse. We were well ahead of schedule in both Eau Claire and La Crosse. The earliest 90 in was April 6th in 1991. Last year La Crosse topped out in the 90s on June 3rd, which was still ahead of schedule.
We are done with the 90s for now though. Earlier today Eau Claire was in the mid 70s and La Crosse was in the low 80s ahead of the cold front. Didn't see much in the way of shower activity this morning and with some peaks of sun we were able to warm up quickly. However, once the front past and winds switched out of the west and eventually northwest our temperatures started dropping. Here's a look how temperatures dropped along with wind speed and direction in Eau Claire this afternoon...
11 AM : 76, SW 15 mph
Noon: 73, W 13 mph
1 PM: 65, W 21 mph
2PM: 60, W 16 mph
3PM: 58, W 14 mph
4PM: 56, NW 13 mph
Usually our warmest temperatures of the day are occurring between 4 and 5pm. Not today...at least here in Western Wisconsin. Here's a look at the surface map as of about 4:23pm. Notice the big spread in temperatures across the state. Out head of the cold front where those wind barbs are out of the south. Highs in the 80s to near 90. Where winds have turned out of the W and NW we have temperatures falling quickly through the 60s and 50s.
Overnight, temperatures will fall into the low 40s as skies clear this evening. We start warming things back up pretty quick to begin this final full week of May. Also, 90s may be back in the 40s towards the end of Memorial Day Weekend.
