DISCUSSION
ISSUED AT 131 PM CDT SAT MAY 16 2026
A PREDOMINATELY DRY AND INCREASINGLY WARM/HUMID FORECAST IS IN
STORE FOR THE REST OF THE WEEKEND INTO EARLY NEXT WEEK AS UPPER
RIDGING STRENGTHENS ACROSS THE GULF AND UP ALONG THE EASTERN
SEABOARD. WHILE SOUTHERLY LOW LEVEL FLOW WILL RESULT IN GRADUALLY
INCREASING MOISTURE VALUES, THE 12Z LIX SOUNDING SHOWED AN
EXTREMELY DRY AIRMASS BELOW 500 MB. THIS WILL TAKE SOME TIME TO
MOISTEN ENOUGH TO RESULT IN CHANCES FOR DIURNAL CONVECTION.
GUIDANCE INDICATES THERE COULD BE ENOUGH LOCALIZED MOISTURE
INCREASE TO SUPPORT A SMALL CHANCE OF AFTERNOON STORMS ACROSS THE
FAR WESTERN AND EASTERN AREAS MON/TUE AFTERNOON. OTHERWISE, THE
REBOUNDING LOW LEVEL MOISTURE COULD SUPPORT THE DEVELOPMENT OF
SOME PATCHY FOG OVER INLAND AREAS DURING THE EARLY MORNING HOURS,
STARTING EARLY SUNDAY MORNING AND PERSISTING THROUGH EARLY NEXT
WEEK. IN FACT, THE PROBABILITIES OF VISIBILITES LESS THAN A HALF
MILE HAVE TRENDED HIGHER (NOW 30-50%) ON THE LATEST HREF FOR EARLY
SUNDAY MORNING. HIGHS THROUGH TUESDAY WILL BE IN THE MID TO UPPER
80S WITH HEAT INDICES CLIMBING INTO THE LOW-MID 90 RANGE BY MON-
TUE, A SIGN THAT SUMMER IS LURKING.
THE SOUTHEAST UPPER RIDGING WILL WEAKEN MID TO LATE NEXT WEEK AS
SERIES OF SHORTWAVES IN SOUTHWEST FLOW BEGIN TO HAVE MORE OF AN
INFLUENCE ON THE REGION. AS A RESULT, DAILY CHANCES OF AFTERNOON
SHOWERS AND THUNDERSTORMS WILL BE ON THE INCREASE FROM WEDNESDAY
THROUGH NEXT SATURDAY. IT CURRENTLY APPEARS THE BEST CHANCES WILL
BE ACROSS WESTERN AND NORTHERN PARTS OF THE AREA, WITH LOCATIONS
FURTHER EAST HAVING SLIGHTLY LOWER CHANCES DUE TO MORE OF AN
INFLUENCE OF THE RESIDUAL UPPER RIDGING. THE LONG RANGE ENSEMBLES
ALSO SUPPORT THIS IDEA AS THE PROBABILITIES OF SEEING WIDESPREAD
RAIN TOTALS OF GREATER THAN 1" THROUGH NEXT SATURDAY RANGE FROM
50-60% IN THE NORTHWEST COUNTIES TO ONLY AROUND 10% IN THE
SOUTHEAST COUNTIES. TRENDS IN THE STRENGTH OF THE SOUTHEAST
RIDGING WILL BE WATCHED CLOSELY AS THAT WILL ULTIMATELY DETERMINE
WHICH AREAS WILL HAVE THE BEST CHANCE OF SEEING ADDITIONAL
BENEFICIAL RAINFALL. 34/JFB
