...A LOW PRESSURE WAVE WILL BRING SHOWERS AND POSSIBLE SEVERE
WEATHER ACROSS THE CENTRAL HIGH PLAINS THIS MORNING...
...ROUNDS OF HEAVY RAIN AND EMBEDDED THUNDERSTORMS ARE EXPECTED TO
STRETCH FROM THE SOUTH-CENTRAL PLAINS THROUGH THE MID-MISSISSIPPI
VALLEY, MIDWEST, AND INTO THE OHIO VALLEY FOR THE NEXT COUPLE OF
DAYS...
...LOCALLY HEAVY RAIN AND STRONG THUNDERSTORMS MOVING ACROSS THE
INTERIOR MID-ATLANTIC THIS MORNING...
MUCH OF THE ACTIVE WEATHER FOR THE NEXT COUPLE OF DAYS WILL
CONTINUE TO BE FOCUSED IN THE VICINITY OF A SLOW-MOVING FRONTAL
BOUNDARY STRETCHING FROM THE SOUTH-CENTRAL PLAINS THROUGH THE
MID-MISSISSIPPI VALLEY, MIDWEST, AND INTO THE OHIO VALLEY. THE
STRONGEST THUNDERSTORMS ARE EXPECTED TO TRAVERSE THE TEXAS AND
OKLAHOMA PANHANDLES EARLY THIS MORNING, AND THEN WEAKEN DURING THE
DAY AS THEY MOVE FARTHER EAST. ROUNDS OF HEAVY RAIN AND EMBEDDED
THUNDERSTORMS CAN ALSO BE FOUND THIS MORNING ACROSS THE CENTRAL
PLAINS INTO THE MIDWEST, FOLLOWED BY ADDITION SHOWERS AND
THUNDERSTORMS FORMING AND MOVING ACROSS LOWER MICHIGAN DURING THE
DAY TODAY.
BY MONDAY, A LOW PRESSURE WAVE IS FORECAST TO ORGANIZE ALONG THE
FRONT AND MOVE NORTHEAST ACROSS THE SOUTH-CENTRAL PLAINS. SHOWERS
AND EMBEDDED THUNDERSTORMS CAN BE EXPECTED TO ACCOMPANY THE LOW AS
WELL AS THE FRONTAL BOUNDARY. BY TUESDAY MORNING, SHOWERS AND
EMBEDDED STRONG THUNDERSTORMS ARE EXPECTED TO MOVE ACROSS THE
MIDWEST TOWARD THE OHIO VALLEY AS THE LOW PRESSURE CENTER TRACKS
ACROSS THE REGION.
ACROSS THE INTERIOR MID-ATLANTIC, A SUBTLE UPPER-LEVEL DISTURBANCE
IS DELIVERING A ROUND OF HEAVY RAIN WITH STRONG TO LOCALLY SEVERE
THUNDERSTORMS MOVING FROM NORTH TO SOUTH THIS MORNING. MEANWHILE,
RECENT WET WEATHER IN THE VICINITY OF CAPE COD IS LINGERING INTO
THIS MORNING. AS THE SLOW-MOVING COASTAL CYCLONE BEGINS TO SLIDE
FURTHER OUT INTO THE ATLANTIC, THE RAIN IS FORECAST TO END DURING
THE DAY TODAY.
THE HIGH-ELEVATION OF CENTRAL COLORADO IS WAKING UP TO SOME WET
SNOW DUE TO AN INFLUX OF COLDER AIR ASSOCIATED WITH THE UPPER LOW.
THE UPPER LOW WILL LIFT INTO THE SOUTHERN PLAINS, ALLOWING MUCH
OF THE WESTERN U.S. TO REMAIN DRY FOR THE NEXT COUPLE OF DAYS WITH
NEAR NORMAL TEMPERATURES. COLDER AIR WILL SURGE DOWN THE PLAINS
BEHIND THE FRONT BUT 90S WILL BE COMMON IN THE AFTERNOON ACROSS
THE SOUTH INTO THE INTERIOR EASTERN U.S. AHEAD OF THE FRONT.
