JUNE 2025 WILL BEGIN WITH AN ANOMALOUSLY DEEP LOW PRESSURE SYSTEM
DEPARTING NEW ENGLAND AS INCREASINGLY UNSETTLED WEATHER IS
FORECAST TO SET UP ACROSS THE SOUTHWEST SUNDAY INTO MONDAY, AND
THEN ACROSS THE MID-SECTION OF THE COUNTRY MONDAY INTO TUESDAY.
AS THE DEEP CYCLONE GRADUALLY MOVES FURTHER INTO SOUTHEASTERN
CANADA TODAY, RAIN ACROSS INTERIOR NEW ENGLAND WILL CONTINUE TO
TAPER OFF. THE SIZE AND PROXIMITY OF THIS SYSTEM WILL CONTINUE TO
BRING GUSTY WINDS THROUGH MUCH OF THE NORTHEAST FOR TODAY WHILE
FUNNELING IN MUCH COOLER AIR INTO THE REGION FROM CANADA.
FARTHER SOUTH, SCATTERED THUNDERSTORMS ARE EXPECTED ACROSS THE
SOUTH-CENTRAL PLAINS TODAY ASSOCIATED WITH A FORMING FRONTAL
BOUNDARY TRAILING FROM A WEAK LOW PRESSURE WAVE. SOME OF THE
THUNDERSTORMS WILL ALSO EXTEND FARTHER EAST ACROSS THE TENNESSEE
VALLEY INTO THE SOUTHERN MID-ATLANTIC REGION IN ASSOCIATION WITH
THE EASTERN EXTENSION OF THE FRONT. THESE ACTIVITIES ARE EXPECTED
TO LARGELY DISSIPATE BY TONIGHT AS A COOL AND MORE UNSTABLE HIGH
PRESSURE SYSTEM SETTLES AND DOMINATES THE EASTERN U.S. BY MONDAY.
WHILE THE EASTERN U.S. ENJOYS COOL AND MOSTLY FINE WEATHER, AN
INCREASINGLY UNSETTLED WEATHER PATTERN IS SETTING UP ACROSS THE
WESTERN U.S. A STRONG COLD FRONT ARRIVING FROM THE PACIFIC IS
BRINGING AN END TO THE RECENT SPELL OF HEAT ACROSS THE
NORTHWESTERN PART OF THE COUNTRY. THIS FRONT WILL GRADUALLY PUSH
INTO THE NORTHERN PLAINS ON MONDAY BEFORE COLLIDING WITH MOISTURE
STREAMING UP FROM MEXICO AND THE SOUTHERN ROCKIES TO PRODUCE A
AROUND OF HEAVY RAIN AND SEVERE THUNDERSTORMS ACROSS THE
MID-SECTION OF THE COUNTRY MONDAY INTO TUESDAY. THE MOISTURE
COMING FROM MEXICO IS ASSOCIATED WITH AN UPPER-LEVEL LOW WHICH
CARRIES SOME OF THE REMNANT MOISTURE FROM FORMER EASTERN PACIFIC
TROPICAL STORM ALVIN. THIS BATCH OF MOISTURE IS EXPECTED TO BRING
A AROUND OF SHOWERS AND SCATTERED THUNDERSTORMS ACROSS THE DESERT
SOUTHWEST TONIGHT AND THEN MOVE INTO THE FOUR CORNERS ON MONDAY
WHERE LOCALLY TERRAIN-ENHANCED RAINFALL COULD POSE A RISK FOR
FLASH FLOODING. THE NORTHERN PIECE OF MOISTURE IS ASSOCIATED WITH
THE PACIFIC COLD FRONT MUTUALLY INTERACTING WITH A HIGH PRESSURE
SYSTEM BUILDING SOUTH FROM WESTERN CANADA. THIS INTERACTION IS
FORECAST TO BRING A ROUND OF RAIN FOR THE NORTHERN ROCKIES INTO
THE NORTHERN HIGH PLAINS TONIGHT INTO MONDAY MORNING WITH GUSTY
WINDS.
MONDAY WILL LIKELY FIND A LOW PRESSURE SYSTEM DEVELOPING OVER THE
CENTRAL HIGH PLAINS WITH A SHARP FRONT EXTENDING ACROSS THE
NORTHERN PLAINS. THE DYNAMICS ASSOCIATED WITH THE SHARP FRONT
WILL TRIGGER SHOWERS AND POSSIBLY SEVERE THUNDERSTORMS WHICH ARE
EXPECTED TO FORM OVER THE CENTRAL HIGH PLAINS MONDAY EVENING, THEN
SPREADING RAPIDLY EASTWARD ACROSS THE NORTHERN PLAINS THROUGH
MONDAY NIGHT INTO TUESDAY MORNING BEHIND THE SHARP FRONT. HEAVY
DOWNPOURS ASSOCIATED WITH THESE STORMS CAN RESULT IN FLASH
FLOODING ISSUES. IN ADDITION, THESE STORMS CAN PRODUCE VERY LARGE
HAIL AND DAMAGING WINDS. BLUSTERY NORTH TO NORTHWESTERN WINDS
BEHIND THE FRONT WILL USHER MUCH COOLER AIR INTO THE CENTRAL
PLAINS MONDAY NIGHT TO DISPEL THE NEAR-RECORD HIGH TEMPERATURES IN
THE UPPER MIDWEST MONDAY AFTERNOON. SCATTERED THUNDERSTORMS WILL
ALSO BE ACTIVE FARTHER SOUTH AHEAD OF A DRY LINE WHERE SEVERE
THUNDERSTORMS ARE ALSO POSSIBLE DOWN ACROSS THE SOUTHERN HIGH
PLAINS MONDAY EVENING/NIGHT.
ACROSS THE SUNSHINE STATE, TROPICAL MOISTURE IN THE VICINITY OF A
STALLED FRONT IS FORECAST TO LINGER AND GRADUALLY BECOME MORE
FOCUSED ACROSS SOUTH FLORIDA WHERE HEAVY RAIN BECOMES POSSIBLE BY
LATER ON MONDAY.
