SYNOPSIS
DRY CONDITIONS TODAY BEFORE CHANCES OF PRECIPITATION RETURN
MAINLY PITTSBURGH AND TO THE SOUTH OVERNIGHT AND MONDAY. DRY
CONDITIONS, A WARMING TREND IN TEMPERATURES, AND ABUNDANT
SUNSHINE CAN THEN BE EXPECTED THROUGH MUCH OF WEEK.
NEAR TERM /THROUGH TONIGHT/
MID AND UPPER LEVEL CLOUDS WILL INCREASE TODAY WITH WEAK
ISENTROPIC LIFT AHEAD OF LOW PRESSURE APPROACHING FROM THE
MIDWEST. LOCAL AND UPSTREAM 12Z SOUNDINGS SHOW A DRY LAYER
EXTENDING UP TO NEAR 700MB (CURRENT RADAR RETURNS TO THE WEST
ALL THE WAY TO INDIANA WOULD JUST BE VIRGA) SO NO PRECIPITATION
IS EXPECTED DURING THE DAY.
A SHORTWAVE WILL INCREASE RAIN CHANCES TONIGHT BUT PRECIPITATION
WILL BE LIGHT AND LARGELY PITTSBURGH AND TO THE SOUTH AS A
FRONT DROPS DOWN OUT OF THE NORTH.
SHORT TERM /MONDAY THROUGH MONDAY NIGHT/
THE BETTER CHANCE FOR RAIN LOOKS TO BE MONDAY LATE MORNING AND
INTO THE AFTERNOON AS THE AFOREMENTIONED (AND WEAKENED) LOW
PRESSURE PASSES SOUTH OF THE FORECAST AREA. PRECIPITATION
SHOULD MAINLY BE PITTSBURGH AND TO THE SOUTH.
TEMPERATURES WILL BE COOLER ON MONDAY WITH THE BOUNDARY SOUTH OF
THE REGION AND COOL NORTHERLY FLOW IN PLACE.
LONG TERM /TUESDAY THROUGH SATURDAY/
DRY CONDITIONS, A WARMING TREND IN TEMPERATURES, AND ABUNDANT
SUNSHINE CAN BE EXPECTED THROUGH MUCH OF WEEK WITH HIGH PRESSURE
THE DOMINANT FEATURE. THE TIMING OF THE NEXT LOW PRESSURE SYSTEM
CONTINUES TO BE A BIT UNCERTAIN BUT ENSEMBLES INDICATE POSSIBLE
RAIN CHANCES LATER ON FRIDAY.
AVIATION /14Z SUNDAY THROUGH THURSDAY/
VFR CONDITIONS EXPECTED THROUGH THE DAY WITH INCREASED MID/HIGH
CLOUDS. MVFR CIGS WILL BE POSSIBLE OVERNIGHT ALONG WITH A FEW
LIGHT SHOWERS (MAINLY KPIT AND SOUTH) WITH A CROSSING
DISTURBANCE.
