DISCUSSION

RAIN-FREE AND BREEZY CONDITIONS WITH SEASONABLE TEMPERATURES WILL BE
THE THEME THROUGH THE FORECAST PERIOD OR THROUGH NEXT WEEK. A 591-
594 DAM SUB-TROPICAL HEAT RIDGE WILL BE THE DRIVER OF OUR DRY AND
TRANQUIL WEATHER PATTERN THROUGH THE FORECAST PERIOD.
NEXT WEEK, DEEP SOUTH TEXAS WILL SIT ON THE WEST-SOUTHWEST FLANK
OF THE ANOMALOUSLY STRONG HEAT DOME AS IT LOOKS TO SHIFT TOWARDS
THE MIDWEST/GREAT LAKES REGION, WHICH WILL RESULT IN A WIDESPREAD
HEAT WAVE ACROSS THE CENTRAL AND EASTERN U.S.
AN ENHANCED PRESSURE GRADIENT NEAR THE SFC WILL RESULT IN BREEZY
CONDITIONS AT TIMES THROUGH THE FORECAST PERIOD. SOUTHERLY WINDS
15-25 MPH COULD GUSTS UP TO 40 MPH NEARLY EACH DAY. WINDS COULD
GUSTS OVER 40 MPH AT TIMES, PARTICULARLY FRIDAY THROUGH MONDAY.
SINCE THE HEAT RIDGE/DOME WILL NOT BE DIRECTLY OVERHEAD, TEMPS
WILL BE OF SEASONABLE LEVELS. DAYTIME HIGH TEMPERATURES WILL RANGE
BETWEEN THE MID 90S CLOSE TO THE COAST TO NEAR 100F DEGREES FAR
WEST/INLAND EACH DAY. MEANWHILE, OVERNIGHT LOW TEMPERATURES WILL
BE IN THE MID 70S ACROSS THE NORTHERN RANCHLANDS TO THE UPPER
70S/LOWER 80S ALONG THE RIO GRANDE VALLEY EACH NIGHT. DESPITE
THESE SEASONABLE LEVEL TEMPERATURES, THERE WILL CONTINUE TO BE
WIDESPREAD MODERATE (LEVEL 2 OF 4) HEAT RISK ACROSS THE REGION
THROUGH NEXT WEEK WITH PEAK HEAT INDICES RANGING BETWEEN 100-110F
DEGREES.
