A strong storm system will emerge from the Rockies today, pushing a dryline into North Texas. Showers and thunderstorms will develop along the boundary during the afternoon hours. A few storms could be strong or severe, mainly east of the I-35 corridor. To the west of the dryline, critical fire weather conditions are expected with gusty southwest winds and relative humidity values falling below 25%. A Red Flag Warning covers this area.
Cool and dry air will move across the region on Monday in the wake of a cold front. Afternoon temperatures will still be near or above normal with highs generally in the upper 50s to the lower 60s. West to northwest winds in the 10 to 20 mph range with gusts to 30 mph will be common which will elevate the threat for wildfires across the region, especially along and west of a line from Bowie to Weatherford to Glen Rose where a Fire Weather Watch has been issued from noon until 6 PM.
With fire weather concerns both today and Monday, it is important to emphasize that a majority of wildfires in Texas are caused by humans and their activities. Do NOT toss lit cigarettes on the ground. Do NOT drag tow chains on the ground. Do NOT park/drive over tall grass. Do NOT leave a campfire unattended. Do NOT burn unnecessarily. Check local burn bans/fire danger. Check the latest weather forecast. Contact law enforcement or the fire department if you smell smoke or see fire.
A cold front early Monday morning will usher in cooler (but seasonal) temperatures that will prevail throughout the workweek. Increasing clouds and rain chances will return on Friday in advance of the next cold front.
