One More Relatively Mild Day…A southwesterly air flow will combine with just enough early sun to help boost temperatures into the 40s for one more day. Enjoy as colder air arrives to close the week!
A cold front will pass through the state tonight. A broken band of showers will accompany the frontal passage later this evening. Light will be the key word (0.10″ or less). As colder air filters into central Indiana, scattered snow showers will develop by Friday morning.
Things begin to turn more interesting Friday afternoon as the upper level low pressure system drops south and individual spokes of energy ride into central Indiana. As this takes place, the combination of very cold air aloft and just enough instability (byproduct of daytime heating- yes even this time of year) will warrant conditions that should help heavier and more intense snow bursts (or squalls) develop. While we’re not talking about widespread heavy snow accumulation, these squalls will be intense enough to impact travel throughout the region when encountered. Please plan accordingly and give yourself extra drive time tomorrow afternoon/ evening if you have travel plans. Once the sun sets, the snow squall activity will quickly diminish in coverage and intensity.
Additional periods of light snow can be expected throughout the weekend as individual upper level disturbances cross through the area. At this time, Sunday appears to offer up the best chance of more widespread, organized light snow. We’ll also need to keep an eye to our northwest for one more trailing feature Monday PM into Tuesday (the “caboose,” if you will, in the seemingly unending weekend train of upper level disturbances).
By the middle part of next week, we’ll be able to catch our breath and await the potential of a bigger, moisture-laden storm system impacting the area late next week…
Make it a great Thursday! We’ll be back later this evening with an updated video discussion focused on the long range…
