Last week we had some ups and downs that are first and foremost a real taste of the arctic air. After dropping to 20 degrees Tuesday morning, we passed 50 degrees on Wednesday and again on Thanksgiving Day. More swings are on the way.
Clouds returning to central Indiana this evening will increase and thicken overnight, providing some relief from the cold and keeping temperatures in the area from dropping to the cold levels we had early Friday. . As it was chilly on Friday, the cold set the mood for the lighting ceremonies in downtown Indianapolis. There is already a warm-up in the works, more noticeable on Saturday afternoon.
It is part of a fast moving river of air that carries the fast moving low pressures, “clipper” storms in the state. We warmed up briefly on Saturday with southwest winds raising the temperatures to a more seasonal feel. Mid-years to over 40 are expected on Saturday before another cold front sweeps through the state.
The smoother airflow and increased tempo of the thunderstorm system are likely to bring some showers to the area in the afternoon and evening. Coverage will be minimal to less than 20% and will target more north-central Indiana.
Winds will pick up again overnight with the passage of another front, a cold front passing Sunday before dawn, bringing down cooler air to end the holiday weekend. This could be the last of the “clipper” storms for a period of time as the jet stream flattens and more warming sets in. Once again, the temperature reversal will begin with a new warming in the middle of the week and perhaps an opening in December with a heat of more than 50 °. Stay tuned!
