NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
235 PM EDT FRI JUL 3 2026
WHAT HAS CHANGED
CONTINUING TO FINE TUNE HEAT HEADLINES AND STORM CHANCES BASED
ON LATEST GUIDANCE AND OBSERVATIONS. FLASH FLOOD THREAT SUNDAY
INTO MONDAY IS INCREASING.
KEY MESSAGES
- 1) EXTREME HEAT AND HUMIDITY CONTINUES THROUGH THE
INDEPENDENCE DAY HOLIDAY WEEKEND WITH SOME RELIEF EARLY NEXT
WEEK.
- 2) AN INCREASED RISK FOR SEVERE THUNDERSTORMS THROUGH THE
INDEPENDENCE DAY HOLIDAY WEEKEND.
- 3) INCREASING CONCERN FOR THE THREAT OF FLASH FLOODING BOTH
SUNDAY AND MONDAY AFTERNOON/EVENING.
DISCUSSION
KEY MESSAGE 1...EXTREME HEAT AND HUMIDITY CONTINUE THROUGH THE
INDEPENDENCE DAY HOLIDAY WEEKEND WITH SOME RELIEF EARLY NEXT
WEEK.
RECORD TEMPERATURES WILL CONTINUE THROUGH MUCH OF THE UPCOMING
INDEPENDENCE DAY HOLIDAY WEEKEND. AN UPPER RIDGE REMAINS PARKED
ACROSS A VAST PORTION OF THE SOUTHEASTERN U.S. INTO THE
TENNESSEE/OHIO VALLEYS AND MID-ATLANTIC REGION. LOWER
TROPOSPHERIC TEMPERATURES REMAIN VERY ANOMALOUS AND RECORD
BREAKING IN NATURE.
EXTREME HEAT WARNINGS REMAIN IN EFFECT THROUGH THIS EVENING, AND
AGAIN SATURDAY AFTERNOON AND EVENING DUE TO A COMBINATION OF
NEAR RECORD HIGH TEMPERATURES AND ELEVATED HUMIDITY LEVELS.
WINDS REMAIN ON THE LIGHTER SIDE UNDER THIS EXPANSIVE DOME OF
HIGH PRESSURE. SKIES SHOULD STAY MOSTLY SUNNY WITH ANY
CONVECTIVE THREATS LIKELY HOLDING OFF UNTIL THE EVENING (SEE KEY
MESSAGE 2 FOR MORE INFORMATION). OTHERWISE, IT IS A LITERAL
WASH, RINSE, AND REPEAT SETUP HEADING INTO SATURDAY/INDEPENDENCE
DAY.
THIS DOES OFFER A BIT OF TRANSITION IN THE OVERALL PATTERN AS
MID-LEVEL HEIGHTS SLOWLY DECREASE. THESE SUBTLE HEIGHT FALLS
WILL MAKE FOR A SLIGHTLY MORE CHALLENGING TEMPERATURE FORECAST
AS CONVECTION BECOMES MORE ACTIVE DURING THE CORE HEATING
HOURS. HOW MUCH CONVECTION AND CLOUD COVER OVERSPREAD THE REGION
COULD HINDER SOME OF THE DIURNAL HEATING. AT THIS POINT, THE
GUIDANCE KEEPS HUMIDITY LEVELS PLENTY HIGH TO SUPPORT ADDITIONAL
HEAT PRODUCTS. EXTREME HEAT WARNINGS ARE IN PLACE FROM 10 AM
UNTIL 9 PM FOR AREAS EAST OF THE BLUE RIDGE. HEAT INDICES AGAIN
REACH THE 110 DEGREE MARK, SLIGHTLY HIGHER TOWARD THE URBAN
AREAS AND ALONG THE CHESAPEAKE BAY. FOR THE SHENANDOAH VALLEY,
IT WILL BE ANOTHER DAY OF HEAT ADVISORIES AS HEAT INDICES RISE
TO AROUND 100 TO 103 DEGREES. OVERALL, ADDITIONAL DAILY
TEMPERATURE RECORDS COULD BE BROKEN THROUGH SATURDAY (SEE THE
CLIMATE SECTION NEAR THE BOTTOM OF THIS DISCUSSION).
TEMPERATURES DROP OFF A BIT INTO SUNDAY AS CONVECTION BECOMES A
LARGER PART OF THE EQUATION. HOWEVER, EVEN WITH FORECAST HIGHS
NOW IN THE LOW/MID 90S, ELEVATED DEW POINTS COULD YIELD
ADDITIONAL HEAT HEADLINES (I.E., HEAT ADVISORIES) ON SUNDAY.
KEY MESSAGE 2...AN INCREASED RISK FOR SEVERE THUNDERSTORMS
THROUGH THE INDEPENDENCE DAY HOLIDAY WEEKEND.
THE STORM PREDICTION CENTER OUTLOOKS THROUGH LATE SUNDAY PAINT
THE PICTURE OF AN ACTIVE CONVECTIVE PATTERN AHEAD. A SLIGHT RISK
FOR SEVERE THUNDERSTORMS IS BEING ADVERTISED ACROSS PORTIONS OF
THE AREA DURING THIS PERIOD.
MOST OF THE LOCAL AREA (MID-ATLANTIC) SHOULD REMAIN CAPPED UNDER
UPPER RIDGING WITH FORCING DISPLACED TO THE NORTH. HOWEVER, ANY
STORMS THAT DEVELOP TO THE NORTH MAY MAKE A RUN AT THE I-68/I-70
CORRIDOR THIS EVENING. SOME GUIDANCE ALSO ATTEMPTS TO DEVELOP AN
ISOLATED THUNDERSTORM OR TWO ALONG THE BAY BREEZE OR NEAR THE
BLUE RIDGE MOUNTAINS.
AS THE UPPER RIDGE BEGINS TO UNDERGO SOME WEAKENING, THE THREAT
OF STRONG TO SEVERE THUNDERSTORMS WILL INCREASE THROUGH THE
HOLIDAY WEEKEND. WHILE THE GUIDANCE SHOWS DEEP-LAYERED
WESTERLIES ON SATURDAY, THE FLOW IS ON THE WEAKER SIDE WHICH
WOULD LIMIT THE NEGATIVE INFLUENCE OF THIS FLOW ON CONVECTIVE
DEVELOPMENT. THE LIKELY TRIGGERS FOR DIURNAL CONVECTION WILL BE
AROUND MESOSCALE BOUNDARIES LIKE THE LEE-SIDE TROUGH, AS WELL AS
BAY AND RIVER BREEZES. MULTIPLE DAYS OF INTENSE HEAT AND
HUMIDITY YIELDS SOMEWHAT EXTREME LEVELS OF INSTABILITY (I.E.,
MIXED LAYER CAPES AROUND 3,000 TO 4,000 J/KG IN SOME MODELS).
WITH DOWNDRAFT CAPE VALUES NEARING 1,500 J/KG, SIGNIFICANT WIND
DAMAGE IS NOT OUT OF THE QUESTION WITH MORE POTENT UPDRAFTS.
WHILE DIFFICULT TO HONE IN ON TIMING, MULTIPLE ROUNDS CANNOT BE
RULED GIVEN THE DEGREE OF INSTABILITY IN THE ATMOSPHERE. A
SLIGHT RISK FOR SEVERE CONVECTION REMAINS ACROSS THE ENTIRE
REGION.
THE UPDATED DAY 3/SUNDAY OUTLOOK ALSO BRINGS ANOTHER SLIGHT RISK
DAY TO THE LOCAL AREA. A SERIES OF WEAK TO MODEST PERTURBATIONS
IN THE FLOW WILL WORK IN TANDEM WITH AN APPROACHING NEARBY
FRONTAL SYSTEM. THE POSITION OF REMNANT OUTFLOWS, DEGREE OF
CONVECTIVE DEBRIS, AND ADDITIONAL DEVELOPMENT ARE ALL QUESTIONS
LOOMING FOR SUNDAY'S FORECAST. DESPITE THE UNCERTAINTY, THE
PARAMETERS REMAIN FAVORABLE FOR FURTHER THUNDERSTORM ACTIVITY.
ADDITIONAL CHANCES FOR SHOWERS AND THUNDERSTORMS CONTINUE THROUGH
TUESDAY, ALTHOUGH THE SPEED AT WHICH THIS WEEKEND'S TROUGH
TRACKS SOUTH WILL BE CRITICAL FOR THESE CONTINUED CHANCES TO
MATERIALIZE. ML GUIDANCE SHOWS AN UPWARDS CHANCE IN THUNDERSTORM
& SEVERE POTENTIAL FOR MONDAY, WITH NCAR'S MEDIUM-RANGE AI NWP
GUIDANCE SHOWING A 30%-45% PROBABILITY IN THE 00Z GUIDANCE FOR
MONDAY AFTERNOON/EVENING. SYNOPTIC SETUP IN THE DAYS BEFOREHAND
WILL BE CRITICAL IN UNDERSTANDING THE NATURE & SCOPE OF
THUNDERSTORMS DURING THIS PERIOD.
TEMPERATURES LOOK TO POTENTIALLY DROP AS THIS COLD FRONT TRACKS TO
THE SOUTH BY EARLY TUESDAY, ALTHOUGH DEWPOINTS WILL REMAIN ELEVATED
FOR NOW RESULTING IN CONTINUED HUMID CONDITIONS. NEVERTHELESS, HEAT
INDICES LOOK TO POTENTIALLY DIP BACK INTO DOUBLE DIGITS BY TUESDAY
AFTERNOON IN THE METROS. HIGH PRESSURE MOVES OVER THE REGION
MIDWEEK.
KEY MESSAGE 3...INCREASING CONCERN FOR THE THREAT OF FLASH
FLOODING THROUGH MONDAY.
OUTSIDE OF THE SEVERE POTENTIAL OVER THE NEXT FEW DAYS, WHICH
IS MENTIONED IN DETAIL ABOVE, THERE IS GROWING CONCERN FOR A
FLASH FLOOD THREAT.
FOR INDEPENDENCE DAY, THE THREAT IS MUCH LOWER, BUT STILL NOT
ZERO. AN EXTREMELY MOIST AIR MASS WILL BE IN PLACE OVER THE
REGION, SO STORMS WILL PRODUCE PROLIFIC RAINFALL RATES FOR
THOSE THAT DO GET THEM. HOWEVER, AS MENTIONED ABOVE, THERE IS A
BIG CONCERN FOR DAMAGING DOWNBURSTS, WHICH SHOULD ACTUALLY
MITIGATE THE FLASH FLOOD THREAT BY KEEPING STORMS MOVING.
URBAN/POOR DRAINAGE AREAS WILL HAVE AN ISOLATED FLASH FLOOD
THREAT, BUT IT WILL BE VERY SITUATIONAL, HENCE THE MARGINAL RISK
FOR EXCESSIVE RAINFALL FROM WPC OVER THE AREA. OUTSIDE OF THE
METRO AREAS, MOST LOCATIONS ARE STILL VERY DRY DUE TO THE
ONGOING DROUGHT, SO THE FLASH FLOOD THREAT IS MUCH LOWER.
BY SUNDAY, THINGS START TO GET A LITTLE MORE CONCERNING, BUT
ESPECIALLY BY MONDAY. AS THE UPPER-LEVEL RIDGE CONTINUES TO
BUCKLE, A TROUGH OVER THE GREAT LAKES WILL FORM WITH A COLD
FRONT TRACKING THROUGH THE REGION BY MONDAY. STORMS ON SUNDAY
ARE LIKELY TO TRIGGER AHEAD OF THIS FRONT AND ALONG EXISTING
OUTFLOW BOUNDARIES FROM SATURDAY, TERRAIN CIRCULATIONS, AND
BAY/RIVER BREEZES. STORMS SHOULD GENERALLY BE PROGRESSIVE, BUT
THE THREAT FOR TRAINING INCREASES IF ANY OF THESE EXISTING
BOUNDARIES LINE UP PARALLEL TO THE MEAN FLOW. A LOT OF
UNCERTAINTY WITH THIS, AS WE HAVE TO SEE HOW SATURDAY'S EVENT
UNFOLDS FIRST AND SEE WHAT BOUNDARIES ARE LEFT BEHIND IN ITS
WAKE. BY MONDAY THOUGH, THE SLOW-MOVING FRONTAL BOUNDARY DROPS
INTO OUR REGION. THIS FRONT WILL BE VERY WAVY IN NATURE, BUT
SOME PORTION SEEMS LIKELY TO LINE UP WITH THE MEAN LOW-MID LEVEL
FLOW, WHICH IS OUT OF THE WSW. TRAINING CONVECTION IS MUCH MORE
LIKELY MONDAY AFTERNOON. ADDITIONALLY, SEVERAL DAYS OF
CONVECTION BEFORE MONDAY COULD REDUCE THE FLASH-FLOOD
GUIDANCE, WITH SOME AREAS BECOMING MORE SUSCEPTIBLE. EITHER WAY,
THE URBAN AREAS ARE THE GREATEST AREA OF CONCERN, AS MODEL
GUIDANCE WANTS TO HANG THIS FRONT UP SOMEWHERE NEARBY. WITH
PWATS IN EXCESS OF 2", SKINNY CAPE PROFILES, A DEEP WARM CLOUD
LAYER, AND BOUNDARY-PARALLEL LOW-MID LEVEL FLOW, A LOT OF
INGREDIENTS ARE THERE FOR A MORE WIDESPREAD FLASH FLOODING
THREAT.
AVIATION /18Z FRIDAY THROUGH TUESDAY/
HAVE MAINTAINED VFR CONDITIONS AT ALL TERMINALS FOR THE NEXT 24
TO 30 HOURS WHICH RUNS OUT THROUGH SATURDAY AFTERNOON. WINDS
REMAIN ON THE LIGHT SIDE AND MEANDER BETWEEN WEST-NORTHWESTERLY
BEFORE SHIFTING TO SOUTHWESTERLY. THERE IS STILL A NON-ZERO
CHANCE EVENING CONVECTION APPROACHES THE MASON-DIXON LINE FROM
THE NORTH. IF PROBABILITIES INCREASE, A PROB30 GROUP COULD BE
INTRODUCED ESPECIALLY AT THE BALTIMORE TERMINALS.
RESTRICTIONS DRIVEN BY THUNDERSTORM ACTIVITY BECOME MORE LIKELY
OVER THE HOLIDAY WEEKEND. WHILE DIFFICULT TO HONE IN ON EXACT
TIMING, THE AFTERNOON/EVENING HOURS COULD YIELD FAIRLY
WIDESPREAD SHOWERS AND THUNDERSTORMS. SOME OF THESE STORMS COULD
BECOME SEVERE IN NATURE. OVERALL WINDS START OFF OUT OF THE WEST
BEFORE TURNING MORE SOUTHEASTERLY LATER IN THE WEEKEND.
PERIODIC SUB-VFR CONDITIONS REMAIN POSSIBLE THROUGH MONDAY AND
INTO TUESDAY AS SHOWER AND THUNDERSTORM CHANCES REMAIN POSSIBLE
MONDAY AFTERNOON & EVENING. SOME OF THESE STORMS COULD BECOME
SEVERE RESULTING IN ERRATIC CHANGES IN WIND SPEED AND
DIRECTIONS, POTENTIALLY EXCEEDING 50 KNOTS. FREQUENT LIGHTNING
IS ALSO POSSIBLE WITH ANY STORMS THAT FORM.
MARINE
IN RESPONSE TO EXPANSIVE HIGH PRESSURE OVER THE REGION, WINDS
REMAIN LIGHT AND WELL BELOW ANY HAZARD THRESHOLDS. THE WEAKER
FLOW WILL YIELD A SERIES OF WIND SHIFTS AS THIS RIDGE
RECONFIGURES IN TIME. THE BIGGER ISSUE WILL BE RELATED TO
CONVECTION IMPACTING THE WATERWAYS. WHILE CHANCES ARE LOW, A FEW
STORMS COULD APPROACH THE NORTHERN-MOST WATERS LATER THIS
EVENING/NIGHT. OTHERWISE, AN ACTIVE WEATHER WEEKEND LIES AHEAD
FOR THOSE OUT AND ABOUT FOR THE INDEPENDENCE DAY HOLIDAY.
SPECIAL MARINE WARNINGS MAY BE NEEDED AT TIMES, PARTICULARLY
DURING THE AFTERNOON/EVENING HOURS THIS WEEKEND. BEFORE GOING
OUT ON THE WATERS, ENSURE TO CHECK THE FORECAST AND HAVE
MULTIPLE WAYS OF RECEIVING HAZARDOUS WEATHER INFORMATION.
WIND GUSTS STAY BELOW SCA THRESHOLDS THROUGH MONDAY AFTERNOON. WINDS
COULD POTENTIALLY APPROACH SCA THRESHOLDS MONDAY EVENING BEFORE
DIMINISHING AGAIN TUESDAY. SHOWERS & THUNDERSTORMS REMAIN POSSIBLE
OVER THE WATERS FOR MONDAY AFTERNOON & EVENING, POTENTIALLY CAUSING
ERRATIC WINDS, LIGHTNING, AND STORM-ASSOCIATED WIND GUSTS.
CLIMATE
THERE IS A SIGNIFICANT HEAT RISK THROUGH AT LEAST SATURDAY
(INDEPENDENCE DAY). THE NUMBERS BELOW AREN'T A FORECAST, BUT
RATHER A REFERENCE FOR HISTORICAL CONTEXT FOR COMPARISON. LATEST
FORECAST: WEATHER.GOV/LWX. A NUMBER OF DAILY RECORDS HAVE BEEN
BROKEN AT THE LOCAL AIRPORTS THE PAST COUPLE OF DAYS (JULY 1-2).
