NORTHERN MINNESOTA LATE TONIGHT INTO TUESDAY...
...HEAVY RAIN AND SEVERE THUNDERSTORMS WILL SHIFT FARTHER SOUTH
FROM THE CENTRAL PLAINS TO THE UPPER MIDWEST TUESDAY NIGHT TO

...A HEAT WAVE WILL EXPAND FROM THE CENTRAL PLAINS ACROSS THE
GREAT LAKES, OHIO VALLEY AND THE NORTHEAST TODAY AND REMAIN ACROSS
THE NORTHEAST THROUGH MIDWEEK...
...HEAVY RAIN THREAT EMERGING ALONG THE CENTRAL GULF COAST TODAY,
FOLLOWING BY AN INCREASING HEAVY RAIN THREAT TOWARD THE TEXAS GULF
COAST LATER TUESDAY AND ESPECIALLY WEDNESDAY...
...LATE-SEASON WET SNOW WILL PERSIST ACROSS THE HIGH-ELEVATIONS OF
THE NORTHERN ROCKIES FOR THE NEXT COUPLE OF DAYS...
A VERY ACTIVE WEATHER PATTERN WILL CONTINUE FOR THE NEXT COUPLE OF
DAYS WITH ADDITIONAL COLD AIR INTRUSION AND JET STREAM ENERGY
TRAVERSING THE NORTHWESTERN U.S. THE BATTLE ZONE WILL CONTINUE TO
BE OVER THE NORTH-CENTRAL U.S. WHERE A CLUSTER OF THUNDERSTORMS
CONTAINING SEVERE WEATHER AND HEAVY RAIN IS EXPANDING ACROSS THE
NORTHERN PLAINS. MEANWHILE, A LOW PRESSURE SYSTEM IS FORECAST TO
DEVELOP OVER THE CENTRAL HIGH PLAINS AND INTENSIFY AS IT HEADS
TOWARD AND REACHES THE UPPER MIDWEST BY TUESDAY MORNING. THE
THREAT OF HEAVY RAIN AND SEVERE WEATHER WILL LIFT FARTHER NORTH
INTO THE NORTHERN PLAINS AND THE UPPER MIDWEST ON TUESDAY. BY
TUESDAY NIGHT, WHILE THE LOW PRESSURE CENTER WILL RAPIDLY EJECT
INTO SOUTHERN CANADA, A SHARP FRONT TRAILING SOUTH AND SOUTHWEST
FROM THE LOW WILL LIKELY TRIGGER AN AXIS OF HEAVY RAIN AND SEVERE
THUNDERSTORMS FROM THE CENTRAL PLAINS TO THE UPPER MIDWEST FROM
TUESDAY NIGHT INTO WEDNESDAY MORNING.
THE COLD AIR INTRUSION AND JET STREAM ENERGY ACROSS THE
NORTHWESTERN U.S. WILL ALSO BRING A ROUND OF LATE-SEASON WET SNOW
ACROSS THE HIGH-ELEVATIONS OF THE NORTHERN ROCKIES THROUGH THE
NEXT COUPLE OF DAYS WHERE WINTER STORM WARNING AND WINTER WEATHER
ADVISORIES ARE IN EFFECT. IN ADDITION, THIS ENERGETIC SYSTEM WILL
ALSO BRING QUITE A BIT OF WIND ACROSS THE GREAT BASIN AND THE
NORTHERN ROCKIES TODAY, REACHING INTO THE CENTRAL ROCKIES AND
NORTHERN PLAINS BY TUESDAY MORNING BEHIND A SHARP COLD FRONT.
IN STARK CONTRAST TO THE COOL/COLD, WINDY, RAINY AND EVEN SNOWY
WEATHER ACROSS THE NORTHWEST, A HEAT WAVE IS QUICKLY EMERGING
AHEAD OF THE LOW PRESSURE SYSTEM FROM THE CENTRAL PLAINS, UPPER
MIDWEST, AND INTO THE OHIO VALLEY. THE HEAT WILL SURGE INTO THE
NORTHEAST BY TUESDAY WHERE HIGH TEMPERATURES WELL UP INTO THE 90S
ARE FORECAST AS FAR NORTH AS VERMONT AND NEW HAMPSHIRE. BY
WEDNESDAY AFTERNOON, SOME LOCATIONS IN INTERIOR NEW ENGLAND COULD
SEE TEMPERATURES TOPPING THE CENTURY MARK, WHICH WILL BREAK DAILY
RECORDS AT CERTAIN LOCATIONS. ACROSS THE FOUR CORNERS REGION,
CRITICAL FIRE DANGER CONDITIONS ARE ANTICIPATED TODAY UNDER
PERSISTENTLY DRY CONDITIONS FUELED BY GUSTY WINDS WITH THE
APPROACH OF THE SHARP FRONT.
FARTHER SOUTH FROM CENTRAL AMERICA ACROSS SOUTHERN FLORIDA AND
THROUGH THE WESTERN ATLANTIC, A PLUME OF TROPICAL MOISTURE LURKING
ACROSS THESE AREAS IS BEGINNING TO HEAD TOWARD THE CENTRAL GULF
COAST REGION TODAY. SHOWERS AND EMBEDDED THUNDERSTORMS ASSOCIATED
WITH THIS MOISTURE PLUME ARE EXPECTED TO BRING AN INCREASING
THREAT OF HEAVY RAIN FIRST ALONG THE CENTRAL GULF COAST REGION
DURING THE NEXT COUPLE OF DAYS, WITH A GRADUAL WESTWARD SHIFT IN
THE HEAVY RAINFALL AXIS TOWARD THE WESTERN GULF COAST LATER ON
TUESDAY AND ESPECIALLY BY WEDNESDAY. MEANWHILE, THE NATIONAL
HURRICANE CENTER CONTINUES TO MONITOR THE POTENTIAL FOR A TROPICAL
CYCLONE TO FORM OVER THE SOUTHWESTERN GULF OF MEXICO THROUGH THE
NEXT FEW DAYS. IT APPEARS THAT EAST TO NORTHEASTERLY WINDS WILL
GRADUALLY STRENGTHEN ESPECIALLY ALONG THE LOUISIANA AND TEXAS GULF
COASTS THROUGH THE NEXT COUPLE OF DAYS AS PRESSURE IS FORECAST TO
FALL GRADUALLY IN THE GULF OF MEXICO.
