Indiana’s Weather For Friday

May 11, 2012

Clear, calm, and cool. That’s how Friday started. The overnight weather map showed an area of high pressure right on top of Lafayette, cruising slowly to the east. Today’s winds will shift to the south behind that high, helping to throw another approximately five degrees on the temperature fire.

There were some 30s again, early in the morning in northern Indiana. You have to wonder (don’t say it out loud) if those are the last of the 30s for the season. The 6-10 and 8-14 day outlooks both show a pretty good bias toward warmer than average temperatures.

Did you go for a run after work Thursday afternoon? Consider this. With dew points around 40, instead of 65….the air was about 38% drier than it was during last Saturday’s Mini Marathon.

It won’t be muggy THIS weekend. Saturday morning looks beautiful. Opening weekend ceremonies at the Speedway, and the “Kids Day” on the Circle should be fine. High clouds will gradually thicken in the afternoon in advance of a weak/weekend frontal system. Slight shower chances kick in, especially north of Indy, later Saturday evening. That front will still be a factor on Mom’s Day. Combined with an Ohio River valley disturbance to the south I would say we have a 40-50% chance of seeing showers Sunday. Indy southward could still get grazed by a few showers Monday. Most of the next work week looks dry and warm.

I mentioned this on Thursday’s “Star@Sunrise” weather video: There were exactly 14 hours and 14 minutes on sunlight yesterday in Indy, and that light was spectacular, especially in the later afternoon and evening. I’ve got one of the fancy schmanzy new iPhones with an improved camera, and persuaded a butterfly to sit in the sun while I’ll snapped a shot, which is attached. Yesterday’s 14:14 sunlight window is more than 180 additional minutes of potential daily sunshine compared to six months ago. Who can blame that butterfly?

Nastiest weather today? Low pressure moving into the southern Great Plains will continue to provide a threat for heavy rainfall capable of flash flooding across southeast Texas and southern Louisiana for today and Saturday. Amounts of 2-4 inches will be common across this region through the period, with locally heavier amounts possible

The average high today is 71 and the average low is 51. Records are 89 and 31. The sun rises at 6:34 and sets at 8:50.

The count again today will be on the high side of “Medium-High.” It will fall slightly through Monday, but remain in the “Medium-High” category.


Today: Sunny. High 75.

Tonight: Mostly clear. Low 52.

Saturday: Mostly sunny morning, then a partly cloudy afternoon. High 76.

Saturday Night: Slight shower and storm chances. Low 56.

Sunday: Mostly cloudy with chances of showers and storms. High 72.

Sunday Night: Slight shower and storm chances. Low 56.

Monday: Partly sunny. Slight shower and storm chance. High 72.

Monday Night: Partly cloudy. Low 53.

Tuesday: Mostly sunny. High 75.

Tuesday Night: Mostly clear. Low 56.

Wednesday: Mostly sunny. High 76.

Wednesday Night: Mostly clear. Low 57.

Thursday: Mostly sunny. High 77.
