Area forecast discussion, Sep 8, 4:44 AM EDT, 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
444 AM EDT THU SEP 8 2011

.SYNOPSIS...
BANDS OF HEAVY RAIN AND EMBEDDED THUNDERSTORMS PRODUCED ADDITIONAL
FLOODING AND EXCESSIVE RUNOFF WILL CONTINUE OVER EASTERN SECTIONS
OF PENNSYLVANIA THIS MORNING INTO THIS AFTERNOON. RAINFALL TODAY
WILL BE MORE SCATTERED IN NATURE ACROSS WESTERN AREAS. WHILE THE
HEAVIEST RAINFALL HAS ALREADY FALLEN...A MOIST AND SHOWERY PATTERN
WILL PERSIST THROUGH THE END OF THE WEEK. DRIER AIR SHOULD LEAD TO
STEADILY IMPROVING CONDITIONS SATURDAY INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CATASTROPHIC FLOODING SCENARIO PLAYING OUT OVER MY EASTERN
COUNTIES AS TORRENTIAL OVERNIGHT RAINFALL ADDED TO ALREADY
STAGGERING 84 HOUR TOTALS FROM THE ENDLESS MOUNTAIN REGION OF
NORTHEAST PA TO THE LOWER SUSQUEHANNA RIVER VALLEY. PEMA REPORTS
OVER 450 ROADS CLOSED AND AT LEAST 2 FATALITIES THUS FAR FROM
HEAVY RAINS AND FLOODING. COLUMBIA COUNTY LAW ENFORCEMENT REPORTS
MOST PRIMARY AND SECONDARY ROADS CLOSED DUE TO FLOODING. EXCESSIVE
RUNOFF FROM OVERNIGHT RAINS WILL CONTINUE THROUGH THE MID TO LATE
MORNING HOURS...AND THE FLASH FLOOD WARNINGS (WITH FLASH FLOOD
EMERGENCY WORDING) WHICH HAD BEEN IN EFFECT SINCE LAST EVENING
HAVE GRADUALLY BEEN REPLACED BY AREAL FLOOD WARNINGS FROM SOUTH
TO NORTH THIS MORNING AS ONGOING SEVERE FLOODING AND ADDITIONAL
HEAVY RAINS PREVENT MUCH IMPROVEMENT OVER THE EASTERN THIRD OF MY
AREA.

IF THERE IS ANY GOOD NEWS THIS MORNING...IT'S THAT THE STATIONARY
BAND OF CONVECTIVE RAINFALL WHICH HAD EXTENDED FROM EASTERN VA AND
THE DELMARVA REGION NORTHWARD TO THE ENDLESS MOUNTAIN REGION OF NE
PA AND INTO NEW YORK STATE HAS FRACTURED INTO SEVERAL LINES OF
WEAKER SHOWERS BRINGING A MUCH NEEDED LULL IN THE RAINFALL.
HOWEVER...IT'S FAR TOO LITTLE TOO LATE AS EXTREME FLOODING IMPACTS
ARE JUST BEGINNING TO BECOME KNOWN THIS MORNING. GIVEN CONTINUED
RUNOFF...CONDITIONS WILL ONLY WORSEN THIS MORNING.
THEREFORE...AREAL FLOOD WARNINGS WILL CONTINUE ACROSS MY EASTERN
THIRD OF COUNTIES.

MODEL CONENSUS BACKS 1.5" PW BACK INTO CENTRAL AND NORTH CENTRAL
PA LATER TODAY...WITH SHOWERS EXPECTED TO BACK INTO THESE AREAS AS
A RESULT. HOWEVER THE 2"+ PW WHICH FED EXCESSIVE HEAVY RAINS OVER
EASTERN PA HAS NOW SHIFTED TO TO COAST WHICH IS ALSO A POSITIVE
SIGN. STILL...ANY ADDITIONAL RAINFALL IS UNWELCOME AT THIS POINT.
MY QPF GRIDS DO SHOW AN ADDITIONAL 0.75" TO 1.5" ACROSS PORTIONS
OF THE CENTRAL AND N CENTRAL MOUNTAINS THROUGH TONIGHT.

THE EXTENT OF FLOODING IN SOME AREAS...COMBINED WITH THE
ADDITIONAL RUNOFF FROM HEAVY RAINS OVERNIGHT WILL CONTINUE TO
CREATE DANGEROUS/LIFE THREATENING CONDITIONS ACROSS MOST OF THE
EASTERN PORTION OF OUR CWA.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
DEEP EASTERLY FLOW AND FILLING UPPER LOW OVER THE OHIO VALLEY WILL
KEEP MOIST AND OCCASIONALLY SHOWERY CONDITIONS OVER CENTRAL PA
THROUGH FRIDAY. WHILE HEAVY RAINFALL IS NOT ANTICIPATED TONIGHT OR
FRIDAY...ANY ADDITIONAL RAINFALL WOULD ADD INSULT TO INJURY OVER
THE EAST.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
UPPER LOW FROM THE REMNANTS OF TS LEE WILL SLOWLY DISSIPATE AND
LIFT OUT...KEEPING THE CHANCE OF SHOWERS AND THUNDERSTORMS INTO
EARLY NEXT WEEK...THOUGH DAY TO DAY CHANCES SHOULD DECREASE. A
NORTHERN STREAM SHORTWAVE WILL BRING A FRONT THROUGH THE STATE TUE
INTO WED. HIGH PRESSURE BEHIND THIS FRONT MAY BRING A PERIOD OF
DRY WEATHER TO THE REGION LATER NEXT WEEK.

WHILE TEMPS SHOULD NOT BE FAR FROM NORMAL REMAINS HARD TO SEE A
SEVERAL DAY PERIOD OF DRY AND WARM CONDITIONS. BEST CHC FOR DRY
WEATHER WILL BE MONDAY.

&&

.AVIATION /09Z THURSDAY THROUGH MONDAY/...
INCLEMENT FLYING CONDITIONS WILL PERSIST THROUGH TODAY...WITH
MAINLY IFR CONDITIONS. HARD TO SEE THINGS GETTING MUCH BETTER
THIS AFT...AS WE WILL BE ON THE COOL SIDE OF THE FRONT WITH
LOW CIGS. OTHER PROBLEM WILL BE WIDESPREAD THUNDERSTORMS
THIS MORNING ACROSS EASTERN SITES LIKE LNS...MDT...AND AT
TIMES IPT. IN ADDITION...STRONG DIRECTIONAL SHEAR POSSIBLE
WITHIN A FEW THOUSANT FEET OF THE GROUND...GIVEN INTENSE
WARM FRONT JUST TO THE EAST OF THE SUSQUEHANNA VALLEY.
FAR WESTERN SITES LIKE JST MAY SCATTER OUT FOR A BRIEF
TIME...BUT EXPECT THE PREVAILING CONDITIONS EVEN AT THESE
WESTERN SITES TO BE POOR FOR MUCH OF THE DAY.

A LITTLE IMPROVEMENT AS ONE HEADS INTO THE WEEKEND...AND
EARLY NEXT WEEK...BUT NOT GREAT...AS LOW CIGS WILL BE LIKELY
FOR MUCH OF THE PERIOD...ESPECIALLY AT NIGHT AND DURING THE
EARLY MORNING HOURS...GIVEN THE LACK OF A DRIER AIRMASS BEING
ADVECTED INTO THE AREA ANYTIME SOON.

OUTLOOK...
FRI...MVFR/IFR.
SAT-MON...MVFR BUT POCKETS OF IFR AT TIMES.

&&

.HYDROLOGY...
A FLOOD WATCH REMAINS IN EFFECT FOR THE ERN TWO THIRDS OF THE CWA
THROUGH THURSDAY. AN ADDITIONAL 1-2 INCHES OF RNFL IS EXPECTED
NEAR AND JUST TO THE WEST OF THE SUSQ MAINSTEM...WITH LESSER
AMOUNTS ACROSS THE CENTRAL AND WESTERN MTNS. LOCALIZED VERY HEAVY
ADDITONAL RAINFALL AMTS IN EXCESS OF 4 INCHES ARE PSBL ACROSS OUR
SOUTHEASTERN ZONES. SIGNIFICANT AREAL AND RIVER/STREAM FLOODING
WILL CONTINUE ACROSS ROUGHLY THE ERN HALF OF PENN FOR THE NEXT
FEW DAYS. REFER TO THE MIDDLE ATLANTIC RIVER FORECAST CENTER'S
HOMEPAGE MAP OF CLICKABLE STREAM/RIVER POINTS FOR THE LATEST ON
THE EXPECTED WIDESPREAD MODERATE TO MAJOR /AND IN SOME CASES
RECORD/ FLOODING. THIS INFO CAN BE FOUND AT:
