SHOWERS ARRIVE IN CITY
Light rain pushed east through the state late Tuesday afternoon. It’s the second system in a series that will reach four by early next week. The showers are mainly light, but could make for some slick roads during the evening rush. The showers will be around overnight but are expected to scatter and lose intensity after midnight.
NEED SOME RAIN
Since June 1, the city is running dry. Right now, Indianapolis is more than 1.50″ below normal and could use some relief. Shelbyville is now 3″ below normal for the summer and much of Eastern Indiana is drying up. The prospects for rain are encouraging based upon the current upper-air flow, though. This “northwest” flow pattern trends cooler than normal with small systems riding the jet stream in from the northwest. These disturbances tend to be minor and are hard to time but the chance for rain will return again Friday/Saturday and again Monday. It is still too early to know exactly how much rain is coming. Rainfall this time of year is never distributed evenly. A forecast of rainfall amounts off the long-range models overnight only crank out 1.57″, which is about normal for this time of the year but it is a drier time of the year as well.
Tuesday marked the 7th straight day of below normal temperatures and an even more impressive seven days in the 70’s. This is the coolest stretch to end a July since 1971 (42 years ago) and the cool spell shows no sign of letting up. The forecast through he next 2.5 weeks call for below normal temperatures. The breakout over 16 days keep daily high temps averaging 8 to 11 degrees from normal through mid August.
August 2013 will start on Thursday and cool. The past two Augusts opened in the 90’s: 2012 (95°) and 2011 (91°). This will be the coolest open since Aug. 1, 2009, when the high was only 80°.
NWS 8 -14 day outlook has much of the Eastern U.S. at cooler than normal temperatures.
