Coolest Air Since the Brickyard Returns to Indiana

We've been sort of stuck in this atmospheric holding pattern over the past 3 weeks which did result in the coolest stretches of weather to end a July in Indianapolis in 42 years (July 1971). We did see some warmer temperatures for the first week and half of August but half of the days this month have been normal or below normal. Abnormally warm weather far "northwest" up in Alaska is responsible for driving the cool air southbound into the (upper) Midwest & Ohio Valley region.
The high temperature on Monday of 84° dropped to 76 Tuesday thanks to a cool brisk northwest wind and the passing of a series of cold fronts. Wednesday's morning lows dropped to the lower 50s and the afternoon high only topped the low 70s. This is more typical for late September. The normal high/low for this time of the year is 84/65. This was the coolest temperatures since the Brickyard 400.
Here's a list of select Wednesday morning lows and afternoon highs around the state:
ANDERSON: 53/66
BLOOMINGTON: 50/73
COLUMBUS: 48/70
ELKHART: 48/70
EVANSVILLE: 55/76
FORT WAYNE: 48/72
GARY: 62/66
INDIANAPOLIS: 52/72
KOKOMO: 48/72
LAFAYETTE: 48/72
LA PORTE: 45/67
LOGANSPORT: 46/70
MUNCIE: 45/69
PERU: 48/69
SHELBYVILLE: 50/73
SOUTH BEND: 46/70
TERRE HAUTE: 50/72
VALPARAISO: 50/70

High Pressure will continue to dominate the next few days resulting in clear and sunny skies for both Thursday and Friday. Nights will remain cool in the 50s for Thursday and Friday morning as well. I'm going with a low of 52° for Thursday AM and 56° for Friday AM. Highs should be in the mid to upper 70s for Thursday and Friday.

Too cool for you? Here's a few warm weather notes:



The cool down now is just a fall preview. It won't linger and in fact, the entire 2nd half of the month could potentially see highs 80+.
There's a difference between the weather setup now (left) and the weather setup around the 25th (right). A massive dome of high pressure will move in after this brief cool spell resulting in a warm end to August and perhaps even a warm start to September.
