The June heat is building, but so far it's still no match to 2011. On June 2 of 2011 Houston had already reached it's first 100 degree day, the first of seven that month. On average Houston only sees about three 100 degree days for the whole year. This weekend the 2011 record of 100 degrees hangs on unchalleged by today's 94. By Sunday Houston may equal last years numbers of the mid 90s and also rival the record of 98 set back in 1960. Stay hydrated and wear light colored loose fitting clothing if your planning to spend a little extra time outdoors. Also due to expected high index numbers sunscreen is a must.
