Get those air conditioners and swamp coolers ready to roll because you will be needing them today. The mercury will be climbing and Thornton may see its first 100 degree reading of the year.

The day starts off with clear skies and then some clouds will begin to arrive by mid-morning. They will not be providing much relief from the heat however. High temperatures will top out in the upper 90s, possibly hitting 100 degrees. We do have a slight chance for a PM thunderstorm but expect any that do develop to be high-based and not offer much more than wind.

Tonight, skies will be clearing and overnight lows will drop to the mid-60s. Keep an eye on the temperature with our live weather gauges here.

Our look back at this week in Denver weather history reminds us that severe weather can continue to strike, even during what is normally a relatively calm month. Lightning, hail and flooding are three continuous threats as we see during our look back at history this week.

Well, if you don’t like the heat, then you won’t be happy with today’s weather. In fact, you likely will be less than pleased with the entire week’s forecast.

For today, sunny skies start us off and will be with us through the morning. The afternoon brings a few clouds and just the slightest chance for a thunderstorm after 2:00pm. As the temperatures, look for a high today in the mid-90s, a good bit above the average high for the date of 89 degrees.

Tonight, any storms will end before sunset then skies will clear. Overnight lows will be in the low to mid-60s.

Looking ahead, today may actually end up being one of the “coolest” days of the week. Mercury readings in the mid to upper 90s are expected through the weekend. More here.

A pretty good looking holiday weekend ahead for us however, there will be no break from the heat. We do however have a good chance for some thunderstorms each day.

For Friday, sunny skies start us off followed by an increase in clouds later this morning and into the early afternoon. Highs today will top out in the mid-90s. The afternoon brings a chance for some thunderstorms with the best opportunity coming from about 3:00pm to 6:00pm. Any storm activity should end by 9:00pm and then we will have partly clear skies overnight lows. Low temperatures tonight will dip to the low 60s.

Independence Day brings more of the same. Mostly sunny skies will be above for the most part. Highs will reach the low 90s. The afternoon brings a pretty good chance to see some thunderstorm activity. Saturday evening storm activity should again end by about 9:00pm. Overnight lows into Sunday morning will dip to around 60 degrees under partly clear skies.

Sunday looks much like the previous two days. Sunny skies start us off with some clouds in the afternoon. Highs will be in the low to mid-90s. Some scattered PM showers and thunderstorms will be seen. Have a safe and fun holiday weekend and God bless the USA!

Change is of course the one constant in Denver’s weather but come July, things actually get pretty consistent.

The standard formula for a day in July is a sunny morning, clouds developing in the late morning and early afternoon. Come mid-afternoon, thunderstorms are rolling off of the foothills and into the metro area and the eastern plains. These storms do occasionally reach severe status containing hail, gusty winds and heavy downpours of rain.

Check out our July weather preview for a complete look at what is in store for the month ahead.

As always, an interesting week in Denver and Thornton weather history.  Various severe weather items are noteworthy, none more so than on July 2, 2006 when a teenager wearing an iPod was struck with lightning.  The music player actually contributed to the teen’s injuries by providing a direct route for the electricity into the victim’s head via the headphones.

Today’s weather looks to be much like we saw yesterday. Mercury readings will be well above normal and we stand just a bit of a chance for a thunderstorm.

The day starts off with sunny skies then by late morning / early afternoon some cloud cover begins to develop. High temperatures will again reach the low to mid-90s. After 1:00pm and until about 11:00pm some scattered thunderstorms will develop. As before, coverage is not supposed to be particularly great and strong winds will be the biggest threat.

Tonight, partly cloudy skies will be above and overnight lows dip to around 60 degrees.

A cold front arrives tonight as well that will cool us down tomorrow and bring a better chance for showers Friday. We then heat right back up for the weekend. Get a look in the extended weather forecast here.
