I hope all of you had an enjoyable and cool Memorial Day. I added “cool” to that well wish because today’s afternoon high temperature of 96° marked out hottest day in Lafayette in nearly five years! The last time we saw temperatures this warm was on September 11th, 2013 when we peaked at that same temperature of 96°. In fact, we even tied the day’s record high temperature of 96° set back in 1911. While it appears as though we’ll remain cooler tomorrow, don’t underestimate our Tuesday ahead; high temperatures will again surpass the 90° mark for many of us.
Believe it or not, Lafayette’s anticipated high of 89° isn’t the primary focus of our forecast going forward. We’re keeping a very close eye on a tropical system currently affecting the Gulf Coast and what possible affects it may have on the region over the coming days. The Natural Hurricane Center’s current projection places the remnants of Subtropical Strom Alberto directly over Greater Lafayette on Wednesday afternoon!
In the meantime Tuesday looks like it will be a primarily dry day with organized rain chances only reaching our southernmost counties late Tuesday and early Wednesday. However, as the tropical moisture picks up speed on its way towards Central Indiana will continue to drop heavy rainfall all along its northbound track. Current models suggest that parts of Northern Alabama, Tennessee, Kentucky Indiana and Michigan could receive more than 3” of total rainfall between now and Thursday evening.
It’s still a little early to say that Greater Lafayette is a shoe in for that much precipitation, but the potential certainly exists. As a result, this going to be a situation that we watch very closely over the next 72 hours as it unfolds. While we need the rainfall, that much potential precipitation for an area that has been as rain-starved as Greater Lafayette could lead to flooding concerns.
Once the rain chances subside latter this week, it looks like conditions will somewhat correct themselves; afternoon highs in the mid to low 80s, while still 3° to 7° above average, sound a heck of a lot better than the mid to low 90s like the last couple of days. We’ll have additional updates on our inbound tropical system as more information becomes available over the next few days.
