Our early summertime pattern persists across the DFW Metroplex with hot, humid and rain free conditions the next seven days. Small indications of isolated showers this upcoming mid-week near the Red River have faded away. Currently we are looking at daily highs in the upper 90s to 100, and nighttime lows in the 70s, possibly higher in urban areas.
This is a fairly typical summer pattern for the southern plains. A large upper level high pressure is located directly over the region and shows little signs of moving or weakening for the next week or two. Beyond 10-14 days however, we may experience a weather pattern shift.
The National Weather Service indicates that a long wave trough may help move the high pressure area to our east, and bring a low pressure system to our west. This would at least result in southern winds and an increase in moisture for the region. This pattern may help bring some much desired rain to our region too. The timing on this is still at least 10-14 days out, so confidence in this solution is limited.
An excerpt from the NWS’ forecast discussion:
A POSSIBLE UPPER LEVEL LONG WAVE PATTERN SHIFT IS ADVERTISED IN THE LONG RANGE OR ABOUT 10-14 DAYS OUT...PUSHING THE MEAN HIGH TO THE EAST WITH A MEAN TROUGH OVER THE WEST. THIS MAY ALLOW FOR A WETTER PATTERN TOWARD THE END OF THE MONTH. STILL TOO EARLY TO SAY IF THIS WILL OCCUR AND WE WILL MONITOR THIS WITH TIME.
Stay cool everyone, remember to drink plenty of water if you are spending time outside. Here is a link to some useful heat safety tips from the National Weather Service:
