Heat Continues

It's day four of the Heat Wave that has gripped north Texas. The Heat Advisory that took effect Wednesday at noon continues thru this evening. It includes all of north Texas:

Here's your hour-by-hour forecast for the day and evening. We expect the heat index to top out between 103° and 108° today:

The big dome of heat has its' core out west. It'll shift to the north a little tomorrow:

This will increase our easterly flow here in north Texas. This also taps into some deep tropical moisture that is just to our east. This will help trigger a few afternoon storms in our eastern counties over the next couple of days. The heat will also taper off a little, enough to drop the Heat Advisory at least:

This morning we watched a complex of storms move south over Oklahoma. Most of us will just see some high clouds from the leftovers of this system. The rain-cooled air is heavier than the surrounding hot air. It fans out ahead of the storm in the direction the complex is moving (south).

These outflow boundaries can help trigger storms in the daytime heating of the afternoon. The storms will be northwest of the Metroplex. The chance for some much needed cooling rain is higher to the east of the Metro area this afternoon:

As soon as the upper-level high moves back in overhead of us we get right back to hot and dry conditions. Look for highs in the upper 90's to be back by weeks' end:

Here's your extended. Summer officially starts on Monday. It'll feel like it.
