Somewhat unexpectedly, looks like there is a broken line of small rain showers moving to the west, which may affect Frisco within the next 30 minutes or so. These showers are very small and have no lightning at this time, so I would not anticipate anything more than a brief rainfall to occur.
A heat advisory has been issued for the entire DFW Metroplex, including Frisco. Afternoon heat index values are forecast to to reach or exceed 105F. Currently the forecast for the next 5 days calls for afternoon high temps to exceed the century mark and top out around 101F. Additionally, the very high temps and partly cloudy skies will be ideal for producing very poor air quality and a Air Pollution advisory has been issued. Pollution levels are forecast to reach level red, which is unhealthy for all groups including adults.
Essentially not only will it be extremely hot outside, the air is also very hazardous to breathe. So this means if you don’t collapse from heat stroke within 15 minutes, you may collapse from some severe respiratory aliment due to the horrible quality air, fun huh!?
Yesterday, June 23, was the first day of the season to see 100 degree temperatures at DFW Airport. Statement from the NWS is below.
…First 100-degree day of the season at dfw Airport…
At 243 PM CDT…the temperature at dfw Airport reached 100 degrees.
This is the first triple-digit high temperature of the season.
For Dallas/Fort Worth…the average date of the first 100-degree day
is July 1. This date varies considerably as recent years show…
2008 June 15
2007 August 11
2006 April 17
The average number of triple-digit highs for the season is 16…but
this too can vary greatly from year to year…
2006 43 (7th most on record)
The most 100-degree days in any year is 69 in 1980. There have been
two years without any triple-digit readings…1973 and 1906. (The
highest temperature was 99 degrees in both years.)
…Heat advisory in effect from 2 PM this afternoon to 8 PM CDT
The National Weather Service in Fort Worth has issued a heat
advisory…which is in effect from 2 PM this afternoon to 8 PM
Morning low temperatures of 78 degrees combined with afternoon
heat indices above 105 degrees have prompted a heat advisory
for the urban areas of the dfw metroplex. The advisory will last
through sunset Thursday.
A heat advisory means that afternoon heat index values are
expected to meet or exceed 105 degrees while overnight low
temperatures will not fall below the upper 70s. Persons involved
in vigorous outdoor activities are urged to take frequent breaks
and drink plenty of water. Wear loose fitting and light-colored
clothing. Be sure to check on persons with health problems and
the elderly…as they are the most susceptible to heat exhaustion
and heat stroke. Never leave Young children or pets in an
enclosed vehicle…even for a short time…as temperatures can
quickly rise to life threatening levels.
…Heat indices near 105 expected through this weekend…
Broad high pressure aloft will keep North Texas hot through this coming
weekend. High temperatures will flirt with the century mark each afternoon…
while combining with low level Gulf moisture in place to create heat
indices between 100 and 105 degrees.
If you are expected to be outdoors for long periods of time…or involved
in vigorous activities…remember to take frequent breaks in the shade
or air-conditioned structure. Drink plenty of water and avoid carbonated
or alcoholic drinks. Never leave children…pets or person with health
problems in vehicles…as temperatures inside can heat up to lethal
levels in a matter of minutes.
…AIR POLLUTION WATCH LEVEL RED…

Helpful information regarding what Ozone and Particulate Matter is, in relation to air irritants and regional air quality. This is taken from a public information statement by the National Weather Service in Burlington Vermont. Tampa was subject to Particulate Matter 2.5 problems in the summertime quite frequently.
