MONDAY MORNING WITH GUSTY WINDS...

A RATHER STRONG LOW PRESSURE SYSTEM FOR LATE MAY WAS TRACKING INTO
SOUTHERN NEW ENGLAND EARLY THIS SATURDAY MORNING. THIS SYSTEM IS
FORECAST TO MOVE NORTHEASTWARD THROUGH THE REST OF NEW ENGLAND FOR
THE REMAINDER OF TODAY WHILE BRINGING A ROUND OF MODERATE TO HEAVY
RAIN ESPECIALLY ACROSS THE INTERIOR SECTIONS DURING THE DAY TODAY
ALONG WITH GUSTY WINDS EXPANDING ACROSS THE NORTHEAST. THE COLD
FRONT TRAILING SOUTH FROM THE SYSTEM CENTER WILL BE PUSHING WELL
OFF THE EAST COAST TODAY. NEVERTHELESS, INSTABILITY ASSOCIATED
WITH A COLD UPPER-LEVEL TROUGH BEHIND THE FRONT COULD TRIGGER
ADDITIONAL SCATTERED THUNDERSTORMS ACROSS THE MID-ATLANTIC REGION
THIS AFTERNOON, EVEN THOUGH TEMPERATURES WILL BE COOLER IN THE
WAKE OF THE FRONT. SATURDAY NIGHT INTO SUNDAY MORNING, A
REINFORCING COLD FRONT WILL BRING COOLER THAN NORMAL TEMPERATURES
FROM THE GREAT LAKES THROUGH THE NORTHEAST AND DOWN INTO THE
MID-ATLANTIC, SETTING UP A FAIRLY PLEASANT SUNDAY TO ROUND OUT THE
WEEKEND. SOME RAIN/SHOWERS ARE EXPECTED TO LINGER OVER NORTHERN
NEW ENGLAND SUNDAY INTO MONDAY DUE TO THE PROXIMITY OF THE DEEP
AND LARGE LOW PRESSURE SYSTEM WHICH WILL BE TAKING ITS TIME TO
EXIT EASTERN CANADA.
MEANWHILE, IN CONTRAST TO THE RAIN AND COOLING TREND IN THE
EASTERN U.S., A STRONG RIDGE OF HIGH PRESSURE WILL BRING HEAT AND
DRY WEATHER INITIALLY ACROSS MUCH OF THE WESTERN U.S. AND INTO THE
NORTHERN PLAINS. IN FACT, HIGH TEMPERATURES REACHING DAILY RECORD
LEVELS WILL BE EXPANDING INTO THE GREAT BASIN, IDAHO, AND AS FAR
NORTH AS WESTERN MONTANA TODAY. THE ANTICIPATED HEAT HAS PROMPTED
ANOTHER DAY OF EXTREME HEAT WARNINGS FOR PORTIONS OF SOUTHERNMOST
NEVADA, SOUTHEAST CALIFORNIA, AND NORTHWESTERN MOST ARIZONA.
MEANHWILE, HEAT ADVISORIES REMAIN IN EFFECT FOR MOST OF TODAY
ACROSS THE INTERIOR VALLEYS OF CALIFORNIA, PORTIONS OF NEVADA INTO
EASTERN OREGON, PORTIONS OF IDAHO AND NORTHWESTERN MONTANA.
DRINKING PLENTY OF WATER, WEARING LIGHT COLORED CLOTHING, AND
STAYING IN AIR CONDITIONED AREAS IS ADVISED AS TEMPERATURES SOAR
AS HIGH AS THE MID-110S FAHRENHEIT IN LOWER DESERT LOCATIONS LIKE
DEATH VALLEY, CALIFORNIA. A COLD FRONT FROM THE PACIFIC IS
FORECAST TO BRING RAPID COOLING INTO THE PACIFIC NORTHWEST LATER
TODAY INTO SUNDAY BUT WITH MINIMAL RAINFALL EXPECTED. FARTHER
SOUTH AND EAST, SURGING MOISTURE AHEAD OF THE FRONT ACROSS PARTS
OF THE ROCKIES AND INTERMOUNTAIN WEST WILL SUPPORT HIGH ELEVATION
SHOWERS AND THUNDERSTORMS SUNDAY AFTERNOON AND EVENING. GIVEN THE
ENHANCED MOISTURE BEING DRAWN IN, SOME OF THESE SHOWERS AND STORMS
COULD PRODUCE BRIEFLY HEAVY DOWNPOURS. ACROSS THE DESERT
SOUTHWEST, SHOWERS AND THUNDERSTORMS WILL BE ON THE INCREASE
BEGINNING SUNDAY AS AN UPPER-LEVEL LOW FROM THE PACIFIC REACHES
INTO NORTHERN MEXICO. SCATTERED THUNDERSTORMS CAN ALSO BE
EXPECTED TO DEVELOP ACROSS THE CENTRAL ROCKIES SUNDAY NIGHT. BY
MONDAY MORNING, SHOWERS AND THUNDERSTORMS ASSOCAITED WITH THE
UPPER LOW WILL LIKELY SPREAD FURTHER NORTHEASTWARD INTO THE FOUR
CORNERS REGION.
ACROSS THE NORTHERN ROCKIES INTO THE NORTHERN HIGH PLAINS, A LOW
PRESSURE SYSTEM IS FORECAST TO DEVELOP AS THE PACIFIC COLD FRONT
PROGRESSES FARTHER INLAND. A SWATH OF MODERATE TO LOCALLY HEAVY
RAINFALL IS EXPECTED TO DEVELOP OVER MONTANA (ESPECIALLY CENTRAL
MONTANA) SUNDAY NIGHT INTO MONDAY MORNING AS A SURGE OF COOLER AIR
ASSOCIATED WITH A CANADIAN HIGH PRESSURE SYSTEM ARRIVES TO BRING
GUSTY NORTHERLY WINDS.
ACROSS THE SUNSHINE STATE, SCATTERED SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO LINGER ESPECIALLY FOR THE SOUTHERN PORTIONS OF THE
FLORIDA PENINSULA THROUGH THE NEXT COUPLE OF DAYS DUE TO A STALLED
FRONT.
