Some of us measured as much as 1” of snowfall accumulation earlier Monday morning; that’s certainly never something you want to start your week out with, let alone one in April. Fortunately, I almost can’t believe I’m typing this, there is a significant warmup on the way that’s expected to usher temperatures to their highest heights since October!
The core of high pressure responsible for today’s accumulating snowfall, northerly winds and sub-average temperatures will have the inverse effect on the region over the coming days; it’s just a matter of location. Currently the high is located to our west northwest, supplying the viewing area with a weak northerly wind flow. Over the next 36 hours the High is expected to meander its way towards Oklahoma, make a turn towards Arkansas and eventually head towards Tennessee and the Carolinas. It’s the second half of that trip that will make all of the difference for Greater Lafayette.
By Wednesday evening, the complex of higher pressure will have relocated to the southeastern corner of the country, pumping southerly winds in across Greater Lafayette and helping to drive temperatures at home into the upper 50s and low 60s earlier that afternoon. The warmer weather doesn’t stop there.
The introduction and intensification of an inbound core of low pressure will further facilitate our warmup by teaming up with the complex of lower pressure on Thursday and Friday to create a channel of strong southerly surface winds (gusting as high as 35 mph) to help drive temperatures up to and even above the 70° mark for the first time in Lafayette since October 22, 2017!
I’m going to watch that low very closely as its associated cold front looks quite prominent and could, under the right circumstances, produce potentially severe storms either Friday night or Saturday. In the meantime, let’s focus on that warmth! There are more than enough 60s and 70s on that extended forecast to make up for Monday’s snowfall!
Unfortunately, it does appear as though once that cold front passes on through over the weekend, the cooler-than-average conditions will hold on for a little longer. The Climate Prediction Center is indicating that temperatures look to remain below normal heights during the period of April 15th through the 23rd. Average high temperatures for that week range between 63° and 65°. We’re not quite done with this “winter” yet.
