AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
249 PM EDT THU MAY 10 2012

.SYNOPSIS...
AN UPPER LEVEL TROUGH OVERHEAD WILL SWING TO THE EAST THIS
EVENING. HIGH PRESSURE WILL THEN BUILD INTO THE REGION. FAIR AND
DRY WEATHER WILL RESULT AND WILL LAST THROUGH SUNDAY MORNING. THE
FIRST PART OF NEXT WEEK LOOKS UNSETTLED BUT SEASONABLY MILD WITH
DAILY CHANCES FOR SHOWERS.

&&

.NEAR TERM /THROUGH TONIGHT/...
COLDEST AIR AT 8H SEEMS TO BE OVERHEAD RIGHT NOW ALONG WITH THE
AXIS OF THE 5H TROUGH. FAST NWRLY FLOW IS BRINGING THE EXPECTED
SHOWERS THROUGH DURING THE MIDDLE OF THE DAY AND EARLY
AFTN...RIGHT AT PEAK HEATING. A FEW SMALL HAIL REPORTS HAVE COME
IN...ONE FROM OUR TECH AT THE RADAR SITE. DOWNSLOPE SHOULD TAKE
CARE OF ALL BUT THE STRONGEST SHOWERS AS THEY TRY TO MOVE DOWN
INTO THE LOWERS SUSQ. CLOUDS AND ANY REMAINING SHRA SHOULD DIE
QUICKLY AS THE SUN SETS. SO...WILL ONLY HANG ONTO SLIGHT CHCS FOR
THE EVENING IN THE C AND THEN TAPER THEM OFF TO THE EAST WITH
DRY/CLEAR OVER MOST OF THE REGION FOR THE REST OF THE NIGHT. THE
TROUBLE WITH CLEARING SKIES AND COLD AIR MASS IS THAT IT COULD
MAKE FROST OR EVEN A FREEZE. THE WILD CARD IN THIS FCST IS THE
WIND. TOO MUCH WIND AND IT WILL MIX AND KEEP TEMPS UP A
LITTLE...AND ALSO PRECLUDE FROST IN ALMOST EVERYWHERE BUT WHERE
THE 10M TEMPS GET TO FREEZING. HOWEVER...MOS GUID TAKES KBFD AND
KFIG DOWN TO LESS THAN 4 KTS FOR LATE TONIGHT BEFORE PICKING THEM
UP AGAIN AROUND SUNRISE. IT IS A MARGINAL SITUATION INDEED.
SO...WITH AN EYE TOWARD THE EARLY START TO THE GROWING SEASON AND
WISHING TO ERR ON THE SIDE OF CAUTION...WILL ISSUE A FROST ADVY
FOR MUCH OF THE NW WHERE TEMPS AND WIND COULD ALLOW FROST TO FORM
IN THE VALLEYS. MORE-ELEVATED LOCATIONS EVEN IN THOSE COS WILL
LIKELY STAY MILD ENOUGH TO PRECLUDE FROST. TEMPS ALSO HEADING TO
OR BELOW FREEZING AT KBFD TONIGHT...WITH ALL MOS GUID TAKING THE
AIRPORT BELOW FREEZING...AND THE AIRPORT IS SOME 1KFT HIGHER THAN
MOST OF THE TOWNS/CITIES IN MCKEAN CO.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
AFTER THE COLD START TO THE DAY...TEMPS REBOUND TO SLIGHTLY BELOW
NORMAL MAXES IN MOST PLACES. VALLEY LOCATIONS IN THE SERN HALF
WILL GET TO 70F. SUNSHINE WILL RULE EXCEPT FOR A FEW DIURNAL CU
OVER THE CENTRAL/NRN MTS. WINDS WILL BE JUST AS BREEZY AS
TODAY/THURS SINCE THE SFC HIGH WILL BE JUST AS TO OUR SE AND PRES
GRADIENT ABOUT THE SAME OVERHEAD. STRONG SUBSIDENCE AND RIDGING
ALOFT ARE MOVING OVER ON FRI NIGHT...SO A CLEAR AND MORE-CALM
NIGHT IS EXPECTED. BUT...RH/S SHOULD STAY IN THE 30S...SO WE WILL
WAIT TO CONSIDER ANY MORE/FURTHER HEADLINES FOR UNSEASONABLE COLD
WEATHER EFFECTS.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
AN UPPER TROF WITH ITS AXIS FORECAST TO BE EAST OF THE STATE BY
THE START OF THE PERIOD SHOULD CONTINUE TO LIFT EAST. THIS WILL
BRING A WEAK UPPER RIDGE AND RISING HEIGHTS INTO SATURDAY
PROVIDING A DRY START TO THE WEEKEND WITH MODERATING
TEMPERATURES.

A SHORT WAVE TROF...NOT WELL RESOLVED IN THE MEDIUM RANGE
GUIDANCE... IS STILL FORECAST TO SUPPORT A COLD MOVING THROUGH THE
STATE ON SUNDAY. THIS WILL BRING SHOWERS AND POSSIBLY A FEW
THUNDERSTORMS TO ANY MOTHERS DAY CELEBRATIONS SUNDAY AFTERNOON.

THE WAVE/FRONT ON SUNDAY LOOKS TO BE THE BEGINNING OF LOW
HEIGHTS/UNSETTLED WEATHER WITH BOTH THE GFS AND EC FORECASTING UPPER
TROFFING OVER THE EASTERN U.S. THROUGH MUCH OF NEXT WEEK. KEPT LOW
CHANCE OR SLIGHT CHANCE POPS OVER MUCH OF THE CWA SUNDAY AFTN INTO
WEDNESDAY. NEAR TO BELOW NORMAL TEMPS ARE EXPECTED TO ACCOMPANY THE
CLOUDY/SHOWERY PATTERN.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
SCT INSTABILITY SHRA COULD BRING VSBYS AT JST DOWN TO MVFR
BRIEFLY THROUGH 20Z...BUT OTHER LOCATIONS SHOULD REMAIN VFR EVEN
IF A SHOWER HITS AN AIRFIELD OR TWO LATE THIS AFTN. AOO UNV AND
IPT ARE LIKELY TO HAVE A SPRINKLE...BUT NO REDUCTIONS IN FLIGHT
CATEGORY. THE TIGHT P-GRAD WITH DRY HIGH PRES MOVING IN FROM THE
NW WILL KEEP THE NW WINDS GUSTY INTO THE EARLY EVENING. SKIES WILL
CLEAR RAPIDLY IN THE NW THIS AFTN...THEN OVER THE REST OF THE AREA
THROUGH THE EVENING. SKC OVERNIGHT WITH SUBSIDENCE TAKING OVER.
HIGHER ELEVATION LOCATIONS MAY KEEP 8-10KTS OF WIND THROUGH THE
NIGHT...BUT VALLEYS LIKE IPT WILL PROBABLY GO CALM FOR A FEW HOURS
OVERNIGHT AS THEY DECOUPLE. MIXING SHOULD BRING THE WINDS BACK UP
DURING THE DAY ON FRIDAY...BUT LITTLE OR NO DIURNAL CU WILL FORM
IN SUCH DRY AIR. SKC LASTS INTO SUNDAY AFTN AS THE HIGH MOVES FROM
THE OH VALLEY TO THE SE THIS WEEKEND. WEAK FRONT MOVES IN SLOWLY
FROM THE N ON SUNDAY AND MAY TOUCH OFF A FEW SHOWERS.

OUTLOOK...
SUN-TUES...MVFR CIGS/VSBY DUE TO SHRA/TSRA.

&&

.EQUIPMENT...
KCCX RADAR HAS HAD AN INTERMITTENT PROBLEM FOR A WHILE AND
TECHNICIANS ARE TROUBLESHOOTING THE PROBLEM TODAY. RADAR
