TUESDAY STORMS

A cold front sagging into the state Tuesday afternoon activated scattered thunderstorms just before 2 p.m.  As expected, the favorable area of storm development (South Central Indiana) was the target for a few damaging wind gusts and hail.  One storm showed some rotation south of Bloomington and prompted a tornado warning.  The storm did not produce a tornado but brought some wind damage southwest of the city.  Torrential rain fell over Bloomington, bringing street flooding with nearly 1″ of rain falling in about one hour.  Other severe reports included limbs and a few trees down as well as power lines snapped into Southern Indiana.

COLD FRONT ARRIVES

It was another 90° day here, marking the fifth of the season and perhaps the last for the rest of the month!  A cold front passed the city around 1 p.m. but the official high hit 91° with a heat index topping 95°.  Northwest winds will usher in some of the coolest air here in almost 7 weeks.

The cool air filtering into the state produced 40° lows in North Dakota, Minnesota  and parts of Wisconsin early Tuesday morning.  The A/C will get a big break as the less humid air arrives.  The dew point is tumbling in the wake of the front and it is going to feel amazing. The comfort level will jump as the tropical air drops!

48° Eagle River, Wisconsin

48° Orr, Minnesota

45° Robertson, North Dakota

Area temps are likely to dip into the middle 50’s away from the city.  The last official sub 60° night here was June 14 (nearly seven weeks ag0) but it is possible that in the next few nights, the official thermometer will dip below the 60° mark.  That is rare air for July – and would mark the first official 50° night in a July here in three YEARS! (59° July 1st 2010)

A break out of forecast temperatures over the next 16 days suggests the average high temperature here will run 6 to 8 degrees from normal.  This could be a stretch of air that will not produce a 90° until well into the first week of August.
