DISCUSSION
(TODAY THROUGH SATURDAY)
ISSUED AT 1220 AM CDT SUN JUN 7 2026
ANOTHER WARM AND HUMID EARLY SUMMER NIGHT IS ONGOING ACROSS THE
REGION, WITH TEMPERATURES CURRENTLY RANGING FROM THE MID 70S TO NEAR
80 DEGREES AMID PARTLY CLOUDY SKIES. 00Z SOUNDING AT LCH REFLECTS
MUCH OF THE SAME WITH A PWAT OF 2.21", WHICH IS JUST SHY OF THE
DAILY MAX FOR TODAY'S DATE (2.23"). ALOFT, A SHORTWAVE CURRENTLY
OVER NORTH TX/OK WILL SLIDE OFF TO THE NORTHEAST TODAY, PROVIDING
ONE MORE DAY OF DECENT SUPPORT FOR CONVECTION BEFORE WE SHIFT
TOWARDS A SLIGHTLY DRIER PATTERN LATER IN THE PERIOD.
TODAY, WPC HAS AGAIN OUTLINED THE ENTIRE FORECAST AREA (EXCLUDING
LOWER SE TX) IN A MARGINAL RISK FOR EXCESSIVE RAINFALL. WHILE RAIN
CHANCES ARE OVERALL LOWER TODAY, AND HIGH RES GUIDANCE SHOWS MAINLY
JUST ISOLATED AFTERNOON ACTIVITY, THE PRESENCE OF A VERY MOIST
AIRMASS WILL ALLOW ANY OF THESE SHOWERS/STORMS TO PRODUCE VERY HIGH
RAINFALL RATES. SO WHILE ANY FLOODING WILL LIKELY BE VERY LOCALIZED
TODAY, IT IS STILL SOMETHING TO PAY ATTENTION TO.
MOVING INTO THE WORK WEEK, UPPER RIDGING BUILDS OVER THE EASTERN
CONUS MONDAY INTO TUESDAY BEFORE WEAKENING A BIT THEREAFTER. THIS
WILL ALLOW FOR A MORE TYPICAL SUMMERTIME PATTERN TO COMMENCE, WITH
SMALL RAIN CHANCES DAILY BUT OVERALL DRY WEATHER EXPECTED.
UNFORTUNATELY, THIS MEANS HOTTER TEMPERATURES TOO, WITH HIGHS
EXPECTED TO NEAR OR EXCEED 90 DEGREES AREAWIDE BY TUESDAY. BY THE
LATER HALF OF THE WEEK, WE BEGIN TO APPROACH THE MID-90S ACROSS
INTERIOR PARTS OF THE REGION, WITH SOME LOCATIONS POSSIBLY NEARING
HEAT ADVISORY CRITERIA IF THINGS HOLD UP.
AVIATION
(06Z TAFS)
ISSUED AT 1220 AM CDT SUN JUN 7 2026
A MIXTURE OF VFR AND MVFR CEILINGS ALONG WITH LIGHT SOUTHERLY
WINDS WILL PREVAIL THROUGH THE REMAINDER OF THE OVERNIGHT HOURS.
POST SUNRISE, ANY REMAINING MVFR CEILINGS WILL LIFT TO VFR WHILE
WINDS WILL BECOME BREEZY WITH OCCASIONAL GUSTS. A FEW ISOLATED
SHOWERS OR STORMS WILL BE POSSIBLE THROUGH THE AFTERNOON HOWEVER,
CHANCES ARE RATHER LOW SO OPTED TO LEAVE ANY MENTION OUT OF THE
FORECAST FOR NOW.
MARINE
ISSUED AT 1220 AM CDT SUN JUN 7 2026
A MODERATE SOUTHERLY FLOW WILL OCCASIONAL GUSTS TO NEAR 20 KTS CAN
BE EXPECTED TODAY INTO TONIGHT. TOMORROW THROUGH THE REMAINDER OF
THE PERIOD, LIGHT TO MODERATE ONSHORE FLOW ALONG WITH SEAS AROUND 1-
3 FEET CAN BE EXPECTED. AN ISOLATED SHOWER/STORM OR TWO IS POSSIBLE
EACH DAY, BUT OVERALL DRY CONDITIONS ARE EXPECTED TO PREVAIL.
FIRE WEATHER
ISSUED AT 1220 AM CDT SUN JUN 7 2026
A MOISTURE RICH AIR MASS WILL REMAIN OVERHEAD TODAY KEEPING HUMID
CONDITIONS IN PLACE WITH AFTERNOON MINIMUM RELATIVE HUMIDITY VALUES
OVER 60 PERCENT. ISOLATED TO SCATTERED SHOWERS AND STORMS WILL AGAIN
BE POSSIBLE TODAY, BUT OVERALL COVERAGE SHOULD BE LESS THAN THE LAST
FEW DAYS. RAIN CHANCES WILL DECREASE ON MONDAY INTO EARLY NEXT WEEK
WITH MINIMUM AFTERNOON RELATIVE HUMIDITY VALUES RANGING BETWEEN 50
