DISCUSSION
(THIS EVENING THROUGH NEXT THURSDAY)
ISSUED AT 1212 PM CDT FRI JUN 26 2026
BROAD UPPER-LEVEL RIDGING STRETCHES ACROSS MUCH OF THE GULF
COAST. AT THE SURFACE, HIGH PRESSURE IN THE ATLANTIC CONTINUES TO
KEEP WINDS ONSHORE. FOR THE NEXT SEVERAL DAYS, SHOWERS AND
THUNDERSTORMS WILL BE RARE AS THE UPPER-LEVEL RIDGE CONTINUES TO
BUILD OVERHEAD. THIS RIDGE WILL KEEP CONDITIONS HOT AND DRY, WITH
TEMPERATURES FOUR TO FIVE DEGREES ABOVE NORMAL FOR THIS TIME OF
YEAR. HIGH TEMPERATURES WILL BE IN THE LOW 90S ALONG THE COAST AND
THE MID-90S IN THE INTERIOR PORTIONS OF SOUTHEAST TEXAS AND
CENTRAL LOUISIANA. HEAT INDEX VALUES WILL REACH WELL INTO THE
TRIPLE DIGITS EACH AFTERNOON. EVERYONE SHOULD PRACTICE HEAT SAFETY
BY STAYING HYDRATED AND TAKING BREAKS FROM THE HEAT.
STARTING ON MONDAY, THE RIDGE WILL BEGIN TO SHIFT TO THE
NORTHEAST AS IT STRENGTHENS. THIS SYSTEM WILL CAUSE TEMPERATURES
TO SKYROCKET ON THE EASTERN SEABOARD. THANKFULLY, WE WILL BE ON
THE SOUTHERN EDGE OF THE RIDGE, AND OUR HEAT IMPACTS WILL BE MORE
LIMITED. AS THE RIDGE MOVES NORTH DEEP LAYER SUBSIDENCE WILL
WEAKEN AND, RAIN CHANCES WILL START TO INCREASE, WITH POPS AROUND
50% BY WEDNESDAY AND THROUGH THE END OF THE WEEK. SINCE WE WILL BE
ON THE SOUTH SIDE OF THE HIGH PRESSURE SYSTEM, ANY SHORTWAVE
TROUGHS THAT ROTATE AROUND THE RIDGE WILL MOVE FROM THE EAST TO
WEST. WHICH IS OPPOSITE FROM OUR TYPICAL WEST TO EAST UPPER LEVEL
PATTERN.
ON AN INTERESTING NOTE, A LARGE BLOB OF SAHARAN DUST IS MAKING
ITS WAY ACROSS THE ATLANTIC AND IS CURRENTLY LOCATED OVER
HISPANIOLA. WHILE THE DUST IS NOT MUCH OF A WEATHER CONCERN, IT
WILL LOWER VISIBILITY AND COULD AFFECT GROUPS THAT ARE SENSITIVE
TO POOR AIR QUALITY. IT WILL ALSO CAUSE SUNSETS TO BE MORE RADIANT
EARLY NEXT WEEK.
