Zionsville, IN We’re opening the work week with cold and frosty conditions, but changes are brewing that will provide significant rain, strong winds, and thunderstorms by Halloween. The details are below!
We remain under the influence of high pressure today and this will supply the region with plenty of vitamin D before “cloudier, stormier” times await later this week. After a frosty start to the day, temperatures will moderate very near the 60 degree mark!
Tuesday: Increasing clouds; Nighttime showers; 0.25″; 37/ 58
A warm front will lift through central Indiana Tuesday afternoon. As the warmer, more moist air runs over the top of the chilly, drier air at the surface clouds will develop and we think scattered showers and perhaps a rumble of thunder begin to roll into the state Tuesday evening/ night.
Wednesday: Scattered showers; 0.25″; 52/ 67
We’ll remain in an unsettled weather pattern for the middle of the week. While most of Wednesday looks dry as of now, we can’t rule out a scattered shower or thunderstorm. Wednesday will be a warmer and windy day as south winds blow ahead of our approaching cold front. In fact, temperatures will approach the 70 degree mark for many Wednesday.
Halloween: Showers and thunderstorms; 1.25″; 55/ 65
Showers and thunderstorms will become widespread on your Halloween, particularly Thursday evening and night. Some stronger storms are possible with a severe report or two not out of the question. As of now, our thinking is the more widespread severe threat will remain to our south, and include portions of southwestern Kentucky and western Tennessee. Just make a mental note if your travel plans take you south Thursday.
Friday: Scattered showers; 0.20″; 43/ 59 (falling)
The cold front will push east of the state Friday morning and a cooler air mass will move in for the weekend. We’ll include the mention of left over light showers/ drizzle Friday, but the bigger story will be gusty northwest winds and falling temperatures.
Saturday: Mostly cloudy; Scattered shower (wet snow flake?); 0.05; 36/ 47
A much colder, northwesterly flow will be in control Saturday. This will keep the region much cooler than normal. Some upper level energy will rotate southeast over the region and may be strong enough to generate some scattered showers (potentially mixed with a wet snow flake).
We’ll wrap up the weekend with sunshine returning and cool, crisp fall conditions in place!
