Spring arrives, but snow shows up in 7-day forecast
We're just over an hour into the astronomical start of spring, and right on cue sunshine and near normal temperatures are in play this afternoon. Though no severe weather around there will be a second statewide tornado drill this evening between 7:30-7:45pm.
We encourage you to discuss your severe weather safety plan with your family, or create a plan if you haven't already. Do you have a way to get severe weather warnings? DO NOT rely on OUTDOOR warning sirens… it's outdated technology that serves a limited purpose. We strongly recommend purchasing a weather radio and download the WTHR news or weather app to stay updated and ahead of severe weather. Don't wait until it's too late. You can also sign up for our daily Skytrak13 Personal Forecast that provides forecast updates multiple times a day. Now I will hop down off the soap box.
It will be a pleasant afternoon with highs in the 50s and a much lighter breeze today. Clouds will increase later this evening and a narrow of showers will likely develop along a warm front after midnight.
This precipitation will quickly shut down and push eastward as the warm front lifts north-northeast of Central Indiana. South of this boundary will be our warmest air we'll enjoy for several days. Highs Friday jump into the middle and upper 60s… likely triggering a case of Spring Fever!
Though much of Friday will be dry, an approaching cold front will trigger another line of rain and possibly thunder Friday evening. Timing of this line appears to be between 8pm Friday and 3am Saturday. This mark a change to a colder air mass heading into the weekend.
Highs Saturday will be a good 15 to 20 colder than Friday, but will pale in comparison to the winter chill coming for next week. Thanks to digging jet stream and accompanied cross-polar flow, much of the eastern US will be 15 to 25 degrees colder than normal for several days next week.
Thankfully this is spring… when cold air intrusions don't linger long. That will be the case next week as highs quickly return to the middle 50s Thursday. It should be noted new computer model guidance suggests wintry precipitation is a possibility for the southern third of Indiana Saturday night into Sunday… though low confidence at this time on this occurring.
There's a better chance of snow Tuesday as a potent upper storm is forecast to cross the state, and I'm not going to rule out some accumulation with this feature. Check back as we get closer to next week.
