Central Indiana’s last rain chance for awhile is racing east this evening along a cold front. Post-frontal conditions include a rather gusty wind (20-35mph) and much cooler air that will settle in overnight.
The steady, gusty wind will drive in the chill, but prevent frost from forming tonight. Mother’s Day morning will be unseasonably cold with lows in the mid 30s, and wind chills in the 20s! Thankfully sun, and not rain, will fill the sky for Mom and anyone heading to the Indianapolis Motor Speedway Sunday.
Conditions Sunday night/early Monday morning are more suitable for frost development, and temperatures will make a serious run at the record low of 35° in Indianapolis.
I fully expect rapid air mass modification after Monday… with temperatures quickly going from below to above normal by Wednesday.
The end result will be our warmest air since early September, with highs Wednesday hitting the mid/upper 80s in Central Indiana.
Next chance of rain arrives Wednesday night into Thursday. But what a 7 day forecast. Wind chill in the 20s, frost, near record lows to flirting with 90°. I truly hope you have a happy Mother’s Day and thanks for reading the blog – Sean Ash
