As we end the 2nd week of November and the first half of the month, taking a look back and we can see how much of a warm start it was. With lots of sunshine, dry weather, and a constant flow of warm air, 8 out of 13 days this month have been above normal. Most of the high temperatures in Indianapolis were above 65 and lows were above 40. Some temperatures were as much as 23° above normal and even set numerous records. Normally we should see daily highs below 60 and lows below 40 throughout the month of November.
Here is a look at the temperature observations for the month and how they differ from normal values.

A cold front passed late Wednesday Night putting an end to an
8 day stretch of high temps above 65. Ahead of the frontal passage, we finally received some measurable precipitation for the month. This only brought in a quarter of an inch of precipitation. In wake of the front, temperatures dropped to freezing levels early on Thursday marking our 2nd coldest morning of the month. With high pressure in control, conditions were dry and sunny for Thursday and Friday. High Temperatures on Thursday reached the lower to middle 50s in Central Indiana. With increased cloud cover and the passage of another cold front, temperatures only dropped to the upper 30s for Friday morning and failed to climb out of the 40s for the afternoon.
All eyes are set on the next disturbance passing this weekend. Saturday is starting out dry, cloudy, and cold with temperatures in the upper 20s. Rain will begin to creep in mid-day, picking up in coverage in the afternon and evening. Winds will also be a concern with this storm system gusting up to 50 mph at times. Initially, there will be a warm front passing so temperatures will continue to warm throughout the overnight hours Saturday into Sunday (towards the upper 50s) but a cold front will be trailing behind. Once it passes the temperatures will begin to rapidly cool back from around 58° at 5AM to around 45° at 9AM. Temperatures will then stablize in the middle to upper 40s thru 4PM before falling again as the sun sets. Rain will also quickly end as drier air works it's way in but winds will not subside until late Sunday night.
With a passage of another cold front, winds from the NW will allow a continual flow of Canadian Air into our region which will result in very chilly temperatures for both Monday, Tuesday, and Wednesday but conditions will be dry and sunny. Temperatures for all three days could be normal to below normal. Some areas are likely to dip below freezing in some spots and select highs may fail to get out of the 40s.
As high pressure scoots off towards the East mid week and winds shift, some ridging will allow temperatures to elevate back toward normal to above normal values by Thursday. As ridging deepens, highs may return back above the 60 degree threshold but this warmth will not be as intense as the one we just experienced and it will not persist for as long as well. There are indications another brand of cold air will arrive shortly before the Thanksgiving holiday but there is uncertainty as to whether it will arrive on Saturday, November 21 or Sunday, November 22. For now, I am on the warmer side for Saturday. This pending chill will also offer up our next chance for rain. Will continue to monitor as it develops and will update forecast if needed.
As we near the winter season, arctic air instrusions will become more prevalent resulting in more days with highs below 50° and lows below 35° in the weeks to come. The average low temperatures runs at 32° and below from November 23-March 14.
