Good Morning,

Tuesday’s afternoon high of 8° in Lafayette marked our coldest day in nearly two weeks; temperatures this afternoon ranged between 20° and 25° below the day’s average high. While yesterday’s passing low unleashed the cold air across Greater Lafayette, a potent core of high pressure situated over the Greater Plains continues to pump the Canadian air southeastward towards the region.

Fortunately for us, that very same high is expected to drive temperatures gradually higher for Central Indiana over the next five to six days. Current model data indicates that the core of higher pressure will take up residence over the southeastern United States and remain there into the weekend, all-the-while pumping southerly winds into the region.

It won’t be an immediate turnaround; overnight lows may fall below 0° in some spots and wind chills may linger near -10°. Even tomorrow’s temperatures will remain nearly 15° below average. Thursday, on the other hand, will allow temperatures to approach the freezing mark for the first time in a week; we’ll hit 31° that afternoon!

Afternoon high temperatures are expected to jump between 5° and 12° from each afternoon to the next during the next five days! The latest projections have us reaching the low 50s as early as Sunday afternoon! Even with rainfall, that 51° high will feel like a heat wave after what we’ve dealt with these last few days.
