Area forecast discussion, Jul 31, 1:55 PM EDT, 3 hours 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
155 PM EDT MON JUL 31 2000

UPPER LOW OVER OHIO VALLEY WILL BE OPENING UP TONIGHT AS IT
GRADUALLY EVOLVES INTO AN OPEN TROF BY TOMORROW. THIS WILL ALLOW
SHORT WAVE ENERGY TO EJECT NEWD THROUGH THE GREAT LAKES REGION. WITH
THIS SCENARIO EXPECT SOME SYNOPTIC SCALE LIFT ACROSS THE FA TONIGHT
IN THE FORM OF UPPER DIV AND Q CONV. THIS SHOULD BE ABLE TO COMBINE
WITH ABUNDANT MOISTURE ACROSS THE REGION TO SQUEEZE OUT SOME PCPN.
WILL USE AN EVE PERIOD TO COVER DIURNAL ACTIVITY AS PER THE PAST FEW
DAYS AND WILL THEN CONTINUE LIKELY POPS FOR THE OVERNIGHT.

AS THE SHORT WAVE MOVES THROUGH THE LAKES TOMORROW IT LOOKS LIKE IT
WILL BE CLOSE ENOUGH TO KICK OFF ANOTHER ROUND OF TRW...ESP WITH ETA
CAPES PROGGED AROUND 1500 J/KG. APPEARS AS THOUGH THE WRN AND NRN
ZONES WILL HAVE THE BEST CRACK AT PCPN DUE TO PROXIMITY TO THE SHORT
WAVE BUT DO NOT WANT TO TAPER THE POPS TOO MUCH IN THE JUICY AMS SO
WILL GO LIKELY ALL ZONES.

MAY BE IN FOR SOMEWHAT OF A BREAK IN THE ACTION TUESDAY NIGHT. WHILE
SHORT WAVE AXIS WILL BE CROSSING THE REGION LACK OF UPPER DIV AND Q
DIV SHOULD PUT A DAMPER ON THINGS. WILL GO WITH CHC POPS TO COVER IT.

AMS REMAINS VERY JUICY AND UNSTABLE FOR WEDNESDAY AND AS NEXT SYSTEM
APPROACHES FROM THE WEST. GIVEN THIS...SEE NO COMPELLING REASON TO
BREAK THE RECENT TREND OF LIKELY POPS DURING THE DAYTIME DESPITE
LOWER FWC NUMBERS.

WILL GO WITH A WARMING TREND THROUGH THE PERIOD CLOSE TO MOS.

WORK ZONES SOON.

.BGM...NONE.
