The Cool Off Under Away Will Be Very Brief

This blog was posted shortly after 1pm

F.Y.I.: Days with highs 70+ is up to 48 and Days 80+ is up to 21
The temperature recorded in Indianapolis at 1PM was 75°


You can say bye-bye to that humidity and heat, only temporarily. The title gives that away. Thanks to a Canadian High Pressure & clear skies, the morning low was allowed to drop back into the low 60s this morning (63). Some communities in the state did touch the upper 50s. These areas was to the north and northeast in cities like South Bend, Fort Wayne, Marion, Muncie, and even in Peru. Also, dew point temps went below the magical comfort line of 60°. When this happens the air is comfortable & refreshing too! Dew Points are a measure of moisture in the atmosphere and the higher that number is the more heavier the air is. This coupled with a hot temperatures makes your body work twice as hard. Its not that your body is sweating more, but dense air is not conducive to the evaporation process (your body's way of cooling you off)
As high pressure takes the wheel, this feature will dominate not only today but tomorrow as well. We'll be cooler today with little to no clouds in the sky. Highs for some may not even touch 80. Others, may be right there hitting 80 or 81. The high over the past few days has been in the mid 80s with higher dew points (and higher humidity). Tomorrow, will be another nice sunny day but temperatures will start to go back up but Dew Points will hover right there around "60" meaning it won't be a very uncomfortable day. Expect highs to be at 83 or 84 degrees. Really have to call it Mostly Sunny Today and Tomorrow and Partly Sunny for Friday (a few cumulus clouds will fill the sky).
Starting Friday, under a southerly air flow, we'll be warming things up on cue for summer's official start. The humidity is also set to return so your going to feel the summer seasons arrival in the air. Dew Points go up towards the mid 60s and afternoon high temperatures will be up into the mid, if not, upper 80s. This is only the beginning of what will be a warm start to the summer season. Watching weekend rain or storm chances, which may limit the ability of touching the 90s. Yes, it appears that number will be the talks of the town in the weather department not only for the coming weekend but through out next week and next weekend as well. By this time last year, we had already hit 90s about 12 times and 15 times at months end. Here's some 2012 highlights to your right, of the heat we haven't seen in quite awhile.
One thing I didn't note was, last year we saw 9 days with highs 100+, of which, 7 were record setters. (Of the 10 records w/ temps 90+, 7 of those were for triple digit heat). The hottest temperature of 105° (July 6th & 7th) was 1° shy of tying the all time highest temperature ever to be recorded in Indianapolis which was last record on July 14, 1936.
WHAT MAKES 2013 SO DIFFERENT FROM 2012?
2012 is as rarest as they come. Probably 100 different records were tied or broken I'm not just talking about daily highs and lows. Records were also set for most consecutive days above normal for any month of March (21 Days Recorded) and also most days in July with temps 90+ (27 last year beats 25 in July 1901). These are just a few that deal with temperatures, we also set precipitation records, or actually lack of I should say.
June 2012 finshed as driest June on record with a whooping 0.09". There were 24 consecutive days without measurable precipitation at Indianapolis International Airport beginning June 5th and ending June 28th. This was also a record for June and was the longest period without measurable precipitation since 1983.
A lot of the records last year date back to the early 1900s, particularly the (dry) dust bowl era of 1930s. Since we did have a drought last summer, the dry soils allowed all of the solar energy to go towards heating. Taking this into account, Indianapolis is over 3" above normal in the rain department this year. Since, the soils are saturated this effects the temperatures keeping them down to actually its lowest in a few years. We still have yet to hit our first 90. The latest day a 90 has come within the past 5 years was on June 19th in 2009 and within a 10 year history we had to wait to July 5th of 2006 before we saw our first 90. The year of 2004 did NOT see a temperature 90+ at all.
Here's a look at my chart for first 70s, 80s, & 90s dates since 2003.

Every week the USDA issues its crop report. It was a rough start for Indiana farmers due to record setting rain during the month of April but due to below normal precipitation May and June the farmers have been hard at work. This week they are saying that 100% of the corn crop has been planted and emerged while 100% of the soybean crop has been planted only 97% has emerged so far. Typically, by the end of June both corn and soybean crop are usually emerged. I'd imagine that next week, soybean crop will be 100% emerged. They have also listed crop conditions as follows;
Corn: 1% Very Poor, 3% Poor, 23% Fair, 55% good, 18% Excellent
Soybeans: 1% Very Poor, 4% Poor, 26% Fair, 55% Good, 14% Excellent
Some of the notes attached was last weeks "Derecho" did some wind damage to some crops so farmers are looking to replace those damaged crops listed in very poor or poor conditions.
Here's a week by week progress report on the crops:

Pollen Count has been down this week and is expected to remain in a low-medium to medium category. On a scale up to 12, it will be around a 4-4.5 over the next few days. Right now, grass pollen is the most popular this time of year. Here's a 30 day history:



TROPIC WATCH
Hurricane Trackers (NHC) have there eyes set on Tropical Depression Two (former Invest 93L). They are deploying the Air Force Hurricane Hunters out today to investigate. They are expecting this to strengthen into Tropical Storm Barry. This will NOT impact the U.S. but instead those in Mexico. As of 8AM, maximum winds sustained are at 35mph with a minimum central pressure of 1006 millibars (mb). This system is moving west northwestward at 9 miles per hour and is expected to take a turn to the West with also a decrease in forward speed.



Tuesday Afternoon, storms past through Eastern Colorado that spawned a (EF1?) tornado at Denver International Airport. The Automated Surface Observing System (ASOS) unit recorded a peak wind gust of 97 mph. Luckily, no injuries or damage was reported. The airport did activate its emergency plan where thousands gathered in stairwells, bathrooms, and basements. Here's a report from one traveler, Ashley Picillo.
"We were very quickly escorted into the shelters. A lot of people were brought into bathrooms. We were actually brought into a lower level stairwell. They brought water in for people, and did a really nice job keeping everyone informed."
KMGH reported that the tornado was spotted on the eastern side of the airport around 2:22pm and was described to be moving northeast at 5 miles per hour before it lifted, weakened and then dissipated. About 45 minutes had past and it was all over and tornado warnings were allowed to expire. The airport resumed normal operations by about 3pm.
Here's a snapshot from one viewer, Mike Sellers.



SPRING'S TIME IS RUNNING OUT
I briefly told you that summer begins this Friday. Here's more info on the official arrival of summer.
The first day of summer is when the summer solstice occurs. This is where the sun is at its nothernmost position resulting in the day with the most daylight hours, a reason why its called the longest day of the year. Since, duration of daylight peaks on June 21st, there is some bad news with summer's official arrival and thats the loss of daylight time. After the summer solstice, the days begin to get shorter. There is good news though, this does not have a direct impact on temperatures for July and August. In fact, this is when the "Dog Days of Summer" occurs. I'll go into details on the history behind that term at a later date but for now you need to know that this is when temperatures are typically at its hottest of the year.
