AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
922 AM EDT MON JUL 22 2013
.SYNOPSIS...
A VIGOROUS UPPER LEVEL SYSTEM WILL SWING ACROSS THE REGION TODAY
BRINGING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS. A VERY MOIST
AND HUMID AIRMASS WILL PROMOTE THE THREAT OF HEAVY RAIN. A COLD
FRONT WILL BRING YET ANOTHER CHANCE OF MORE SHOWERS AND
THUNDERSTORMS ON TUESDAY...BEFORE HIGH PRESSURE FINALLY BUILDS IN
ON WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WIDESPREAD SHOWERS AND EMBEDDED THUNDERSTORMS ARE EXPECTED ACROSS
THE FORECAST AREA TODAY. HOW THEY EVOLVE AND WHERE THE THREAT OF
HEAVIEST RAIN WILL BE IS A LITTLE MORE COMPLEX.
12Z KILN SOUNDING THIS MORNING HAS THE INGREDIENTS FOR A FLASH
FLOOD THREAT. PWATS ARE NEAR 2 INCHES...THE WARM CLOUD DEPTH IS
OVER 4 KM...AND THE CAPE PROFILE IS A SKINNY ONE (MOIST AND
UNSTABLE THROUGH A DEEP PART OF THE ATMOSPHERE). SO...THE QUESTION
WILL BE WHAT FOCUSING MECHANISMS WILL PRODUCE SHOWERS/THUNDERSTORMS
AND WHERE WILL THE HIGHEST THREAT FOR FLASH FLOODING BE.
A MID LVL MESO VORTICITY IS CURRENTLY MOVING INTO CENTRAL OHIO.
ANOTHER MESO VORTICITY IS MOVING INTO THE TRI-STATE REGION.
FARTHER TO THE WEST...A SYNOPTIC SCALE S/WV WAS PUSHING INTO
WESTERN INDIANA. AT THE SAME TIME...A STATIONARY FRONTAL BOUNDARY
WAS DRAPED ACRS OUR NRN CWFA. CURRENT SHORT TERM FLASH FLOOD
THREAT WILL BE ASSOCIATED WITH THE FIRST TWO FEATURES ALONG WITH
SOME LOW LEVEL MOISTURE TRANSPORT AND LIFTING ALONG STATIONARY
FRONT. THE LONGER TERM FLOOD THREAT WILL BE FOR THIS AFTN INTO
EARLY EVENING AS STRONGER S/WV MOVES INTO OUR REGION AND COUPLES
WITH THE BETTER MOISTURE TRANSPORT (AND ASSOCIATED WEAK SFC LOW
RIPPLING ALONG FRONTAL BOUNDARY) TO BRING THE HIGHEST FLASH FLOOD
THREAT TO ALL BUT THE FAR NW CWFA. AS A RESULT...HAVE EXPANDED THE
FLASH FLOOD WATCH UNTIL 8 PM EDT ACCORDINGLY. RAINFALL AMOUNTS
COULD BE 2 INCHES OR MORE PER HOUR.
CLOUD COVER AND PCPN SHOULD HELP HOLD TEMPERATURES DOWN INTO THE
LOWER 80S.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
AS THE S/W AND ASSOCIATED FORCING PUSH E OF THE FA THIS EVENING
THE CONVECTION SHOULD WIND DOWN FROM NW TO SE.
FAST NW FLOW ALOFT THEN BRINGS NEXT SYSTEM INTO THE REGION FOR
TUESDAY...AS A CDFNT SWINGS ACROSS THE GREAT LAKES INTO THE OHIO
VALLEY. ANOTHER ROUND OF SHOWERS AND TSTMS ARE EXPECTED ON TUESDAY
AS THE FRONT DROPS THROUGH. CONVECTION MIGHT LINGER INTO TUESDAY
EVENING...BUT THEN FINALLY IT LOOKS LIKE A DRIER AIRMASS WORKS IN
LATE TUESDAY NIGHT AND WEDNESDAY HAS HIGH PRESSURE SETTLES IN.
MODEL CONSENSUS IS SHOWING THAT HIGHS WILL BE IN THE LOWER TO MID
80S ON TUESDAY...WITH HIGHS ONLY IN THE 70S ON WEDNESDAY.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
MID/UPR LEVEL RIDGE TO BUILD OVER THE WESTERN US WITH SFC HIGH
PRESSURE SLIDING SE INTO THE OHIO VALLEY. THIS HIGH WILL PROVIDE
DRY WEATHER CONDITIONS THRU THE END OF THE WEEK. TEMPERATURES ON
THURSDAY LOOK TO BE A AROUND 5 DEGREES BELOW NORMAL...WITH HIGHS
RANGING FROM THE UPPER 70S NORTHWEST TO THE LOWER 80S SE. READINGS
CLOSER TO NORMAL EXPECTED FOR FRIDAY WITH HIGHS RANGING FROM THE
LOWER 80S NORTHWEST TO THE MID 80S SOUTHEAST.
SHORTWAVE AND ASSOCIATED SFC FRONT TO PROVIDE NEXT CHANCE FOR
PRECIPITATION SATURDAY. WILL CARRY HIGHEST POPS OVER THE SE. SOME
MODEL SOLNS EXIST REGARDING PROGRESSION OF SFC FNT. AT THIS TIME
WILL FOLLOW MORE PROGRESSIVE SOLN AND DRY THE REGION OUT SUNDAY WITH
TEMPS 5 TO 7 DEGREES BELOW NORMAL.
&&
.AVIATION /13Z MONDAY THROUGH FRIDAY/...
SHOWERS OVER THE AREA THIS MORNING WILL CONTINUE AND PRIMARILY
SEE CIGS 10KFT OR BETTER. PROBLEM THIS MORNING IS ANY MVFR BR
ASSOCIATED WITH AND IN THE WAKE OF SHOWER ACTIVITY.
SURFACE LOW PRESSURE WILL TAKE AIM ON THE REGION THIS AFTERNOON
AND SQUEEZE OUT SOME MORE SHOWER AND THUNDERSTORM ACTIVITY. UPPER
LEVEL LIFT WILL ACCOMPANY THE SURFACE FRONT WITH A H5 SHORTWAVE
LOCATED ALONG THE IN/OH BORDER AT 18Z. BOTH THE UPPER LEVEL LOW
AND THE SURFACE LOW WILL MOVE SLOWLY EAST AND LINGER OVER SOUTHERN
OHIO THROUGH 0Z BEFORE EXITING IN THE 0-6Z TIME FRAME.
AFTER THE FORCING FROM THE LOWS MOVE EAST...THERE WILL BE LITTLE
UPPER LEVEL CLOUD COVER AND IFR CIGS AND VSBYS ARE EXPECTED AS THE
CLEARING LETS THE MOIST BOUNDARY LAYER RADIATE AND REACH THE
DEWPOINTS.
OUTLOOK...THUNDERSTORMS POSSIBLE TUESDAY AND TUESDAY NIGHT.
