Cold air arrives, pattern remains unsettled
Temperatures have seen a sharp drop over the last 24 hours as an upper low has dropped into Southern Canada. This low has pushed the colder air in and will keep us unsettled throughout the weekend. The impact of the low will continue to be felt throughout a big portion of the workweek with us continuing to have a small chance for rain.
Mostly cloudy for the day as our weather remains unsettled. While there will be a chance for rain here in Central Indiana, the best chance for seeing any rain will be for northern communities. In fact they won’t only have a chance for rain but I also wouldn’t be surprised to see a sleet report or two.
Highs today will struggle to hit the 50s with most of the day in the 40s. Clouds will be around most of the day and we will call it mostly cloudy with perhaps a break or two with some brief sunshine. By tonight the clouds thin and the winds ease allowing for temperatures to drop into the 30s area wide. There will be a chance outside of Indianapolis for some patchy frost to develop. You should probably protect just in case any tender vegetation you have outside.
Sunday and Beyond:
As the powerful upper low continues to drift off to the northeast it will allow us to warm up. The warm-up won’t be quick with us seeing temperatures ticking up a couple of degrees each day. This means highs in the upper 50s for Sunday and 60s returning for Monday. We have two days with 70s forecast as highs so the warm weather isn’t done just yet. I do think we can say goodbye to the 80s for the rest of the year though.
The best news is that no severe weather is expected over the next week. We will have a couple of fronts that will pass through the state through Thursday. October and November are part of the state’s secondary severe weather season. Looking at climatology, some of the largest and most powerful quasi-linear convective systems have occurred in the fall.
