SHORT TERM
(WEDNESDAY THROUGH THURSDAY)
ISSUED AT 927 AM CDT TUE JUN 23 2026
THE STORM/MCS TRACK SHOULD STAY TO OUR SOUTHWEST WEDNESDAY INTO
THURSDAY. HOWEVER, WE WILL HAVE TO MONITOR THURSDAY A BIT MORE FOR
LIGHT PRECIPITATION WITH DEEPER MOISTURE DUE TO SOUTHERLY FLOW.
FOG MAY BE AN ISSUE ONCE AGAIN WEDNESDAY NIGHT AS WELL, UNLESS LOW
CLOUDS OVERSPREAD THE AREA FIRST. HIGHS WEDNESDAY WILL BE IN THE
LOWER TO MIDDLE 80S WITH LOWS WEDNESDAY NIGHT IN THE MIDDLE TO
UPPER 60S.
LONG TERM
(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 945 PM CDT MON JUN 22 2026
THE PRIMARY CONCERN FOR THE LONG TERM PERIOD IS HEAT. AS AN UPPER
LEVEL RIDGE SHIFTS EASTWARD INTO THE AREA ALONG WITH SFC HIGH
PRESSURE OVER THE GULF, A WARMING PATTERN WILL TAKE SHAPE THROUGH THE
WEEKEND WITH HIGHS REACHING THE UPPER 80S TO LOWER 90S (WITH SOME
SPOTS IN THE MID 90S ON MONDAY). THESE TEMPERATURES ARE NEAR NORMAL
FOR THIS TIME OF YEAR, HOWEVER, OVERNIGHT LOWS WILL BE ~5 DEGREES
ABOVE NORMAL WITH TEMPERATURES DROPPING INTO THE LOW TO MID 70S.
HEAT INDEX TEMPERATURES ARE FORECAST TO REACH THE UPPER 90S TO
AROUND 103 DEGREES. WE WILL ALSO BE MONITORING HEAT INDEX VALUES
MONDAY, ESPECIALLY, AS WE NEAR CRITERIA FOR A HEAT ADVISORY. NWS
HEATRISK HIGHLIGHTS THE AREA IN A MODERATE TO MAJOR RISK, WHICH
MEANS HEAT WILL LIKELY AFFECT ANYONE SENSITIVE TO HEAT (ESPECIALLY
THOSE WITHOUT ADEQUATE COOLING/HYDRATION) AS WELL AS SOME HEALTH
SYSTEMS AND INDUSTRIES. IF YOU HAVE OUTDOOR PLANS THIS WEEKEND, BE
SURE TO PRACTICE HEAT SAFETY SUCH AS STAYING HYDRATED AND SEEKING
SHADE WHEN OUTDOORS TO AVOID HEAT RELATED ILLNESS.
