It’s hard to even imagine a nicer day that today; we hit highs in the mid to low 70s with plenty of sunshine and a comfortable northerly breeze. Today’s high of 73° marks our 8th straight day of 70° or warmer here in Lafayette – our longest stretch of such since the first ten days of October.
Tomorrow appears as though it will be quite similar to day; expect plenty of sunshine and highs in the 70s. The single difference will be tomorrow’s southerly wind flow which will help drive temperatures back into the upper 70s and possibly even low 80s in a few spots. We’ll tip the scales at 77° in Lafayette Tuesday afternoon.
Unfortunately, all good things must come to an end; an inbound core of low pressure paired with a cold front will certainly see to that come Wednesday. We’ll see two rounds of shower and thunderstorm activity that day; the first will reach Greater Lafayette during the late morning and early afternoon.
While the first line won’t amount to little more than your run-of-the-mill showers and thunderstorms, the secondary line of storms expected late that evening appears as though it could become more potent or even intensify surpassing the severe threshold that night.
Current model data suggests that a line of showers and storms will begin to develop across parts of Central Illinois by 7:00 P.M .ET Wednesday. The line will then progress eastward, reaching our westernmost counties by 8:00 P.M. ET that evening. The last of the storms should exit east of the viewing area just after midnight Thursday morning.
Some of the cells embedded within this line may generate damaging winds in excess of 60 mph and hail larger than an inch in diameter. As a result, the Storm Prediction Center of America has placed much of Greater Lafayette, including Tippecanoe County, under a Marginal Risk for Severe Weather for that evening. Weather Team 18 will have more information on the system over the next 48 hours.
