Area forecast discussion, Jun 25, 3:29 PM EDT, 3 hours 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
329 PM EDT WED JUN 25 2014

LATEST UPDATE...
SYNOPSIS/SHORT TERM/LONG TERM/HYDRO/MARINE

.SYNOPSIS...
ISSUED AT 329 PM EDT WED JUN 25 2014

A FEW SHOWERS AND STORMS WILL CONTINUE THROUGH THE EVENING HOURS
BEFORE ENDING BY MIDNIGHT. LOW CLOUDS AND SOME FOG WILL LIKELY
REDEVELOP AGAIN TONIGHT. DRY WEATHER IS FORECAST FROM THURSDAY
THROUGH FRIDAY AS HIGH PRESSURE WILL BE SITUATED ACROSS THE REGION.
CHANCES FOR SHOWERS AND STORMS INCREASE ONCE AGAIN OVER THE WEEKEND
AND INTO EARLY NEXT WEEK AS GULF MOISTURE IS DRAWN BACK NORTH ON
SOUTHERLY WINDS. A COLD FRONT IS EXPECTED TO TRAVERSE THE AREA
MONDAY NIGHT INTO TUESDAY WHEN STORMS WITH HEAVY RAIN ARE A
POSSIBILITY. TEMPERATURES WILL WARM OVER THE WEEKEND INTO EARLY NEXT
WEEK WITH HIGHS WELL INTO THE 80S...EVEN PUSHING TO AROUND 90 SUNDAY
INTO MONDAY.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT)
ISSUED AT 329 PM EDT WED JUN 25 2014

MAIN CONCERNS IN THE SHORT TERM PERTAIN TO STORM THREAT THIS EVENING
AND FOG OVERNIGHT.

REGARDING THE STORM THREAT...NOT THINKING ANYTHING SEVERE AT THIS
POINT. LOCALLY HEAVY RAINS....SMALL HAIL AND WIND GUSTS TO 30-40
SHOULD BE THE WORST OF IT. BETTER SHEAR IS LOCATED TO THE SOUTH OF
THE AREA AND INSTABILITY HAS BEEN MODULATED BY A STRATUS DECK THAT
HAS ONLY SLOWLY ERODED. THAT SAID...LI/S ARE NEAR -4 C ALREADY AND
ML CAPE VALUES ARE AROUND 1000 J/KG. SO MODERATE CAPE...LOW SHEAR
SHOULD END UP WITH SUB SEVERE STORMS. ONLY THE HIGHEST CORES WOULD
HAVE A CHANCE AT SEVERE AS THE CORES DROP. WE WILL MONITORING RADAR
THIS EVENING FOR CORES ALOFT.

FOG IS A PRETTY GOOD BET AGAIN TONIGHT...BUT THINKING IT WILL LIKELY
NOT GO QUITE AS DENSE. DRIER AIR IS TRYING TO ADVECT IN ON NORTHEAST
WINDS WHICH SHOULD ALLOW FOR SLIGHTLY BETTER VSBY/S AND A LITTLE
LESS STRATUS.

FAIRLY QUIET WEATHER IS EXPECTED THURSDAY THROUGH FRIDAY NIGHT WITH
RIDGING IN PLACE. MOISTURE RETURN DOES START AS EARLY AS FRIDAY
NIGHT AND MATCHED NEIGHBORING WFO/S IN THE WEST WITH SOME SLIGHT
CHANCE POPS FOR SHOWERS AND STORMS LATE.

.LONG TERM...(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 329 PM EDT WED JUN 25 2014

A COUPLE OF CHALLENGES COME INTO THE PICTURE DURING THE LONG TERM
WHICH INCLUDES HEAT AND THUNDERSTORM CHANCES.

THIS WEEK ENDS WITH SOME RATHER COMFORTABLE AND TRANQUIL WEATHER ON
FRIDAY AND TRANSITIONS INTO A MUCH WARMER AND HUMID PATTERN OVER THE
WEEKEND. A PRONOUNCED RIDGE WILL BEGIN TO DEVELOP OVER THE EASTERN
PORTION OF THE CONUS. AS A RESULT...SOUTHERLY WINDS DEVELOP WITH
PLENTY OF WARMTH AND MOISTURE MAKING A RETURN TO THE REGION. LLJ
PLACEMENT MAY BE KEY TO THE EXTENT OF THE STORM POTENTIAL. AT THIS
POINT IT SEEMS AS THOUGH THE LLJ LAGS BACK INTO WISCONSIN ON THE
LATEST RUNS. THIS MAY BE SOMETHING TO PAY ATTENTION TO AS THE TIME
DRAWS NEAR. NONETHELESS...SOME SCATTERED STORMS CANNOT BE RULED OUT
WITH THE INCREASINGLY SOUPY AIRMASS OVER THE WEEKEND.

AN AGGRESSIVE SYSTEM THEN PLOWS INTO THE UPPER MIDWEST LATE INTO THE
WEEKEND. EVEN WARMER AIR DRAWS NORTH ON MONDAY WHICH COULD LEAD TO
TEMPERATURES THAT DRAW CLOSER TO THE 90S. A FRONT WILL LIKELY MOVE
IN LATE MONDAY INTO TUESDAY BRINGING THE SHOT FOR ORGANIZED STORMS
GOING INTO EARLY TUESDAY. TIMING MAY NEED TO BE ADJUSTED THROUGH THE
WEEKEND WITH THIS SYSTEM.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 154 PM EDT WED JUN 25 2014

RAPID IMPROVEMENT SHOULD CONTINUE THIS AFTERNOON WITH THE EROSION
OF MORNING FOG. CEILINGS ARE ALSO SHOWING IMPROVEMENT AND SHOULD
CLIMB INTO VFR LEVELS. THE LAKE BREEZE WILL MAKE SOME PROGRESS
INLAND POSSIBLY SPARKING A FEW STORMS...HENCE THE VCTS CARRIED IN
THE TAFS. ANY STORMS THAT DEVELOP WILL QUICKLY FADE THIS EVENING.
FOG ONCE AGAIN BECOMES A CONCERN OVERNIGHT TONIGHT. WINDS BECOME
LIGHT
AND VARIABLE WHILE LOW LEVEL MOISTURE CONTINUES TO BE STUBBORN.
CONDITIONS WILL SUPPORT IFR CATEGORIES TONIGHT BEFORE IMPROVEMENT
BEGINS DURING THE MID MORNING HOURS.

&&

.MARINE...
ISSUED AT 329 PM EDT WED JUN 25 2014

MAIN MARINE CONCERN IN THE SHORT TERM WILL CONTINUE TO BE FOG.
EXTENDED THE MARINE DENSE FOG ADVISORY THROUGH 1000 AM THURSDAY AS
IT APPEARS THE LIGHT GRADIENT WILL ALLOW THE MOISTURE TO HANG AROUND
AT LEAST THROUGH TONIGHT. WE CAN REASSESS THE THREAT OF DENSE FOG
OVER THE LAKE TONIGHT AND AGAIN THURSDAY MORNING.

SOUTHERLY GRADIENT WILL INCREASE SATURDAY INTO MONDAY. WAVES WILL BE
ON THE INCREASE DURING THIS TIME FRAME...ALTHOUGH IT WILL BE A WARM
AIR ADVECTION WIND OVER A COLD LAKE. SO...THE WINDS WILL LIKELY NOT
MIX DOWN ENTIRELY.

&&

.HYDROLOGY...
ISSUED AT 329 PM EDT WED JUN 25 2014

RIVERS ARE ELEVATED ACROSS SOUTHWEST LOWER MICHIGAN WITH MOST SITES
IN THE 90TH PERCENTILE OR HIGHER. THE EXCEPTION IS ACROSS CENTRAL
LOWER MICHIGAN WHERE CONDITIONS ARE A LITTLE BIT BETTER...70-80
PERCENTILE. BOTTOM LINE...RIVERS ARE UP FROM RECENT RAINS. THE ONLY
ADVISORY IN THE AREA IS AT IONIA CURRENTLY.

RAINFALL THIS EVENING SHOULD BE SOMEWHAT SCATTERED AND ONLY LOCALLY
HEAVY WHICH SHOULD NOT AFFECT THE RIVERS TOO MUCH. A COUPLE OF DRY
DAYS THURSDAY AND FRIDAY SHOULD HELP.

RAINFALL OVER THE WEEKEND AND INTO EARLY NEXT WEEK WILL NEED TO BE
WATCHED GIVEN THE ELEVATED RIVER LEVELS. GULF MOISTURE WILL BE DRAWN
NORTH DURING THIS TIME FRAME SO HEAVY RAINS ARE NOT OUT OF THE
QUESTION.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...NONE.
