Tonight’s Forecast:

This evening will be a warm one with lows only dropping to the lower 80s. Saharan dust is still with us bringing a hazy sky and a reduced air quality.

Wednesday’s Forecast:

It will be another incredibly hot day with mostly sunny skies and highs in the triple digits. A heat advisory is in place for SE Texas until 8PM Wednesday with high temperatures reaching 99 to 103 degrees and heat index values up to 109 degrees. An excessive heat warning has been issued for our NW counties Wednesday for air temperatures up to 106 degrees. Stay cool and be safe in this dangerous heat.

A Red Flag Warning goes into effect from 10 a.m. to 10 p.m. for our northern counties Wednesday. These urgent warnings are given when the weather conditions are hot, dry and breezy enough, that if a fire starts, it can spread rapidly.

Record setting hot July:

We are on track to set the hottest July on record in Houston. Our records go back to 1889. Temperatures have been in the upper 90s to 100+ for all but three days this month. We also set the record for the hottest June in Houston. The other thing to watch is how many 100 degree days we have this month. 1980 set the record with 18 100 degree days. So far we’ve are at 10, putting us in third place behind 1980 and 1998.

Dreaded dome of high pressure is back:

The dome of high pressure that brought seven straight days of triple digit temperatures to SE Texas two weeks ago is back. This mid-level dome is not a typical high pressure area. This high pressure sinks the air, that sinking air compresses. Compressed air is a hot air. This kind of pattern is a lot more about physics than meteorology but it all translates to dangerous heat.

10-day Forecast:

The numbers speak for themselves. There is no major relief in sight.
