AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
302 PM CDT TUE JUL 7 2015

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 301 PM CDT TUE JUL 7 2015

MUCH QUIETER WEATHER TODAY WITH A RIDGE OF HIGH PRESSURE OVER THE
AREA AND COOLER AND DRIER CONDITIONS. THIS RIDGE IS EXPECTED TO
SLIDE SOUTHEAST TONIGHT...FOR ANOTHER NIGHT OF GOOD RADIATIONAL
COOLING AND ANOTHER COOL NIGHT ACROSS THE FORECAST AREA. THIS TIME
NORTHWEST WISCONSIN TO GET DOWN AROUND 40...AND MAINLY LOW TO MID
40S ELSEWHERE. EXPECT THE NORMAL COOL SPOTS WILL ONCE AGAIN BE
CLOSE TO IF NOT JUST BELOW 40. WEDNESDAY THE RIDGE SLIDES FAR
ENOUGH SOUTHEAST TO ALLOW WARMER AND MORE HUMID AIR TO FLOW INTO
THE AREA ON THE SOUTHERLY RETURN FLOW...ESPECIALLY AS A WEAK COLD
FRONT WILL BE APPROACHING FROM THE NORTHWEST. THIS FRONT TO SERVE
AS A FOCUS FOR SHOWERS AND THUNDERSTORMS DURING THE LATE AFTERNOON
HOURS...BUT OTHERWISE WE WILL JUST HAVE WARMER TEMPS AND HIGHER
HUMIDITY VALUES. MAX TEMPS 3-5 DEGREES WARMER THAN TODAY IN THE
LOW TO MID 70S.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 301 PM CDT TUE JUL 7 2015

A WEAK SFC FRONT AND ASSOCIATED UPPER S/W WILL BE SLIDING EWD ACROSS
THE INTERNATIONAL BORDER WED NIGHT AND THURSDAY WITH ISOLATED
SHOWERS AND STORMS...MAINLY OVER THE NRN HALF OF THE FORECAST AREA.
AVAILABLE MOISTURE WILL BE MINIMAL WITH THIS SYSTEM...THEREFORE
RAINFALL AMTS WILL BE LESS THAN A TENTH OF AN INCH. WEAK RIDGING
ALOFT WILL COMBINE WITH HIGH PRESSURE AT THE SURFACE BEHIND THE
DEPARTING SYSTEM LATE THUR AND FRI TO KEEP CONDITIONS QUIET. THE
NEXT ROUND OF SHOWERS AND STORMS WILL MOVE IN EARLY THIS
WEEKEND...BUT BE PUSHING INTO A HIGH AMPLITUDE UPPER RIDGE AND
RELATIVELY DRY AIR MASS...WHICH WILL INHIBIT THE AMT OF
PRECIPITATION AND THE EWD MOVEMENT OF THE PRECIP. PATTERN WILL
BECOME MORE PROGRESSIVE LATER IN THE WEEKEND WITH ADDITIONAL CHANCES
FOR SHOWERS AND STORMS INTO EARLY NEXT WEEK.

TEMPERATURES WILL REMAIN ON THE WARM SIDE THROUGH THE EXTENDED
PERIOD WITH AFTERNOON HIGHS IN THE 80S AND OVERNIGHT LOWS IN THE
UPPER 50S AND 60S. A GRADUAL INCREASE IN HUMIDITY THROUGH THE LATTER
PART OF THE WEEK WILL MAKE CONDITIONS FEEL EVEN HOTTER.
