DISCUSSION
ISSUED AT 1239 AM CDT SUN JUL 19 2026
ANOTHER HOT DAY IS ON TAP FOR TODAY. A HEAT ADVISORY HAS BEEN ISSUED
FOR OUR SOUTHEAST MISSISSIPPI COUNTIES FOR HEAT INDEX VALUES UP TO
110. ELSEWHERE, HEAT INDEX VALUES ARE JUST BELOW THE HEAT ADVISORY
THRESHOLD OF 108, BUT STILL VERY WARM WITH MAXIMUM VALUES OF 100-107
EXPECTED. ANYBODY OUTDOORS SHOULD DRINK PLENTY OF WATER AND TAKE
BREAKS IN A/C WHEN POSSIBLE.
THE MAIN STORY THROUGH MID WEEK IS THE DISTURBANCE THAT IS CURRENTLY
OFF THE WEST COAST OF FLORIDA, NOW CALLED INVEST 91L. THE NATIONAL
HURRICANE CENTER HAS UPPED OUR PROBABILITIES TO A 60% CHANCE OF
FORMATION IN 48 HOURS. IT IS CURRENTLY NOT VERY ORGANIZED, BUT
ENSEMBLE GUIDANCE DOES SHOW MORE ORGANIZATION OVER THE NEXT COUPLE
OF DAYS AS IT APPROACHES SOMEWHERE ALONG THE NORTHERN GULF COAST. IF
IT IS ABLE TO BE SAMPLED WITH RECONNAISSANCE TODAY, THAT WILL HELP
INFORM THE MODELS AND HOPEFULLY GET MORE CONSENSUS.
WPC HAS OUR AREA OUTLOOKED FOR EXCESSIVE RAINFALL WITH A MARGINAL
RISK FOR THE WHOLE AREA TODAY AND AREAS JUST ALONG THE COAST MONDAY
AND TUESDAY. WE CURRENTLY HAVE NORMAL MOISTURE WITH PWATS SITTING
AROUND 1.9". LREF ENSEMBLE MEANS SHOW PWATS INCREASING UP TO ~2.25"
WITH THE APPROACH OF THE DISTURBANCE STARTING MONDAY THROUGH MID
WEEK. THESE VALUES ARE CLOSER TO THE 90TH PERCENTILE BASED ON
CLIMATOLOGY. DEEP LAYER FLOW IS PREDOMINATELY SOUTHERLY AND
REINFORCES THE TROPICAL MOISTURE THROUGH THE ATMOSPHERIC COLUMN.
THIS INTRODUCES ENHANCED RAIN RATES WITH EFFICIENT WARM RAIN
PROCESSES IN PLAY WHICH COULD CAUSE SOME FLOODING CONCERNS.
THERE IS STILL UNCERTAINTY IN TIMING AND STRENGTH OF THE SYSTEM AS
WELL AS THE LOCATION OF THE LOW WHICH HELPS DETERMINE OUR IMPACTS.
MUCH OF THE CURRENT MODEL GUIDANCE KEEPS THE CENTER OFF THE COAST IN
OUR AREA AND THEREFORE MOST OF THE RAINFALL FOOTPRINT. THIS TRACK
WOULD KEEP IMPACTS FOCUSED LARGELY ON THE MARINE AREA WITH GUSTY
WINDS, INCREASING WAVE HEIGHTS, AND AN INCREASED RIP CURRENT RISK. A
MORE NORTHERN TRACK WITH THE CENTER JUST ALONG OR INLAND WOULD BRING
MORE QPF AND FLOODING IMPACTS TO THE AREA.
AFTER INVEST 91L, WE ARE ON THE EASTERN PERIPHERY OF A BUILDING
UPPER RIDGE UNDER GENERALLY NORTHERLY FLOW. THIS BRINGS RAIN CHANCES
TO A MORE NORMAL SUMMERTIME PATTERN WITH DAILY CHANCES FOR ISOLATED
TO SCATTERED SHOWERS AND THUNDERSTORMS, ESPECIALLY ALONG THE SEA
BREEZE AND RESULTANT OUTFLOW BOUNDARIES.
..BEACH FORECAST
THE RIP CURRENT RISK WILL INCREASE TO A HIGH FOR FLORIDA BEACHES
MONDAY AND ALABAMA BEACHES ON TUESDAY WHICH WILL LAST THROUGH
WEDNESDAY.
