LATEST FORECAST DISCUSSION
Meteorologist: Drew Williams
*NEAR RECORD HEAT PLUS SUNSHINE TO START OFF THE MEMORIAL DAY WEEKEND.*
After hitting 90 on Thursday for the first time this year in Eau Claire, we'll see more summer-like heat for the beginning of Memorial Day weekend. (The typically first 90 degree day in Eau Claire is June 8, so it's safe to say we're ahead of schedule.) Today will feature sunshine with just a few clouds helping to warm things up. The jet stream will remain well to the north in Canada, with upper level ridging over the area. A very warm air mass will arrive from the southwest and with plenty of sunshine we are likely to see another afternoon with highs in the low to mid 90's across Western Wisconsin. In fact, we could be very close to records this weekend. The record today is 93, set in 1914 and 91 on Sunday, set in 1969. I have a forecast high of 92 this afternoon, so we'll be really close to that record high today. Probably a better chance to break the record on Sunday. Though it will be hot, humidity is forecast to be a bit lower and with the upper level ridge, conditions will not be that favorable for storm development. But a pop up shower is possible later today. For the most part we will remain dry today and Sunday.
Memorial Day will also be hot, and with a surface high sliding to our east, we will start to see an increase in humidity again. This could lead to a stray afternoon or evening storm, but it still looks like most places will remain dry. Highs will again be near 90. The upper level ridge will slowly start to weaken next week, allowing temperatures to slowly drop into the middle of next week.
The next front will also be moving from the Plains to the east, leading to an increasing chance for showers and storms again by later next Tuesday and Wednesday. A break from the wet weather Thursday and Friday, highs will remain above average, in the 80's.
