AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
322 PM EDT SAT JUL 27 2013
LATEST UPDATE...
SYNOPSIS/SHORT TERM/LONG TERM/HYDRO/MARINE
.SYNOPSIS...
ISSUED AT 304 PM EDT SAT JUL 27 2013
A SLOW MOVING LOW PRESSURE SYSTEM WILL REMAIN OVER THE GREAT LAKES
REGION THROUGH MONDAY. THIS SYSTEM WILL LEAD TO MOSTLY
CLOUDY...COOL AND UNSETTLED WEATHER. HIGH PRESSURE WILL MAKE ITS
WAY INTO THE AREA BY TUESDAY LEADING TO A WARMING TREND.
&&
.SHORT TERM...(THIS EVENING THROUGH MONDAY NIGHT)
ISSUED AT 304 PM EDT SAT JUL 27 2013
THE MAIN CHALLENGE IN THE SHORT TERM DEALS WITH THE TIMING AND
AMOUNT OF ANY RAIN. OVERALL I FEEL THAT MODELS ARE NOT SHOWING
ENOUGH RAIN GIVEN THE RELATIVELY WARM LAKE...AMOUNT OF COLD AIR
ADVECTING IN...AND FAVORABLE LOW LEVEL WIND CONVERGENCE NEAR THE
LAKESHORE IN THE SHORT TERM. SHOULD BE SOME LOCATIONS SEEING OVER AN
INCH OF RAIN...PROBABLY VAN BUREN INTO ALLEGAN COUNTIES BY THE END
OF THE EVENT.
FOR TONIGHT THE RADAR AND MODEL TRENDS SHOW
LITTLE SUPPORT FOR STEADY RAIN THROUGH ABOUT 06Z...BUT AFTER THAT
THE DGZ MOISTENS UP. THAT COMBINED WITH LAKE ADDED MOISTURE WILL
SUPPORT MOST LOCATIONS SEEING RAIN BY DAYBREAK. POPS WILL FEATURE
LIKELY OR BETTER VALUES.
THE AIRMASS WILL BE PLENTY COLD ENOUGH FOR LAKE EFFECT SUNDAY.
WITH GENERAL WESTERLY FLOW AND THE UPPER LOW OVERHEAD...MOST
LOCATION WILL BE SEEING SHOWERS FROM TIME TO TIME. BEST LOW LEVEL
CONVERGENCE IS OVER THE WESTERN HALF OF THE CWA. WEAK INSTABILITY
SHOWS UP SO A RISK FOR THUNDER EXISTS.
ANOTHER BATCH OF DEEPER MOISTURE WRAPS AROUND THE UPPER LOW BEFORE
IT DEPARTS MONDAY. SHOULD BE A WET NIGHT...ESPECIALLY CLOSER TO
THE LAKESHORE. POPS WERE ADJUSTED UP AS RESULT.
DAYTIME TEMPERATURES WILL BE WELL BELOW NORMAL INTO MONDAY.
.LONG TERM...(TUESDAY THROUGH SATURDAY)
ISSUED AT 304 PM EDT SAT JUL 27 2013
TEMPERATURES WILL MODERATE BACK TO NEAR NORMAL FOR THE MIDDLE
PORTION OF THE WEEK WITH FAIR WX ANTICIPATED TUESDAY. A WEAK LOW
PRESSURE SYSTEM WILL BRING POTENTIAL FOR SCATTERED SHOWERS AND
TSTORMS WEDNESDAY THROUGH WEDNESDAY NIGHT AND SOME MEDIUM RANGE
GUIDANCE TRENDS INCLUDING THE ECMWF SUGGEST THAT SOME OF THIS
ACTIVITY MAY LINGER INTO EARLY THURSDAY.
FAIR WX SHOULD BRIEFLY RETURN LATE THURSDAY THROUGH FRIDAY BEFORE
ANOTHER LOW PRESSURE SYSTEM OVER THE LOWER GREAT LAKES AND OHIO
VALLEY REGIONS BRINGS POTENTIAL FOR MORE SHOWERS AND STORMS FRIDAY
NIGHT AND SATURDAY. TEMPERATURES LATE IN THE WEEK THROUGH THE
WEEKEND SHOULD AVERAGE FAIRLY CLOSE TO NORMAL.
&&
.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY)
ISSUED AT 1250 PM EDT SAT JUL 27 2013

THUNDERSTORMS THROUGH MID AFTERNOON AT OUR EASTERNMOST TERMINALS
(KLAN AND KJXN). WNW WINDS MAY GUST TO NEAR 20 KTS AT TIMES THIS
AFTN AND EARLY EVENING.

WITH SCATTERED SHOWERS THAT WILL BE MOST PREVALENT AT OUR WESTERN
TERMINALS OVERNIGHT. THEY WILL GRADUALLY ADVANCE FURTHER EAST TO
AFFECT ALL TERMINALS ON SUNDAY WITH PRIMARILY MVFR CONDITIONS
ANTICIPATED AT ALL THE TERMINALS SUNDAY.

.MARINE...
ISSUED AT 304 PM EDT SAT JUL 27 2013
