After the early morning clouds, the skies cleared for a beautiful open to the work week in central Indiana. Clouds and rainfall haven’t been terribly frequent so far this young October, and if you are a fan of sunny days, you are in luck. A sprawling area of high pressure will deliver cool nights and sunny, warmer afternoons.
October annually is the fourth sunniest month of the year, with 61% of possible sunshine, and this year has produced 51%. It is a little off track, but that will change over the next several days.
Cooler and much drier air flows behind a passing cold front, and under clear skies, we are headed to only the second night all season below 50-degrees in Indianapolis. The forecast low of 46° is actually a more seasonal low. Outlying areas that early Saturday morning dipped into the lower 40s will likely reach low 40s again early Tuesday.
WARMER DAYS – STREAK TO CONTINUE
Autumn 2019 is on a breakneck pace, with now 84% of the days above average. The current stretch of 29 consecutive days above normal will keep rolling along as several more days this week will be above to well above normal. Late week, temperature highs will reach the 80-degree mark. The current average temperature ranks this autumn as the WARMEST on record to-date. That status will hold entering the upcoming weekend.
Looking longer range, there is a strong likelihood that temperatures will take a dive, and the streak could be in jeopardy late weekend and early next week. Off overnight computer forecasts, a rather profound buckle in the jet stream should send cooler than average temperatures our way. The chill forecast could produce the first night in the 30s for many outlying areas early Tuesday morning — stay tuned!
JUST ADD RAIN
Weekend rainfall was welcome but not enough to put a dent into a growing deficit. Along with the warmest fall on record to date, it is also the third driest entering the work week. We’ve only had 18% of the normal rainfall, totaling .69″, a full 3″ below normal. There is little to no rain expected until we reach late week when a stronger cold front will race into the state. Current thinking is that warm winds will blow before showers and t-storms approach late Friday. Rainfall could reach nearly 80% of the area late Friday into Saturday morning. Throw in a chance of a thunderstorm, some decent rainfall could fall. We will monitor trends.
