.PREV DISCUSSION... /ISSUED 330 AM CDT FRI AUG 10 2007/
DISCUSSION...
SYNOPSIS...
A VERY WARM OVERNIGHT IS AGAIN IN PROGRESS WITH OUR URBAN LOCATIONS
(HSV/UAH-NWS/DCU/MSL) AT 2 AM ALL REPORTING TEMPS AOA 80F...WITH THE
HIGHEST AT DCU WITH 84F AIDED BY A WEST WIND AT 5KT.
LIKEWISE...MEMPHIS SITS AT 86F AND NASHVILLE AT 87F. THE UAH/MIPS
PROFILER HAS SHOWN A LLJ MAX OF 20-25KT AND WARM ADVECTION IN THE
LOWEST 1KM THIS MORNING...POSSIBLY AIDING THE WARMING JUST ABOVE THE
SFC. IN THE PAST HOUR...THE MIPS/KHTX PROFILERS SHOW A TROF PASSAGE
JUST ABOVE THE SURFACE THROUGH ABOUT 2 KM...EXHIBITING A WIND SHIFT
TO THE NW-N. WATER VAPOR IMAGERY SHOWS THE TAIL END OF THE GREAT
LAKES TROF EXTENDING INTO THE LAND BETWEEN THE LAKES REGION OF
WESTERN KY/TN WHERE LATE AFTERNOON/EVENING THUNDERSTORMS ERUPTED
EARLIER. AT THE SURFACE...A COOL FRONT LAGGED THE TROF EXTENDING
FROM NEAR BOWLING GREEN KY TO BETWEEN MEMPHIS AND JONESBORO AR. A
PRONOUNCED THETA-E RIDGE AND DEW POINT POOLING WAS NOTED ALONG THIS
BOUNDARY...WITH RUC SHOWING PWS 1.5-2 INCHES ALONG THE
FRONT...PEAKING OVER THE MEMPHIS AREA. ELEVATED CAPES WERE FAIRLY
HIGH IN THIS REGION (2000+ J/KG). A ROGUE SHRA RE-DEVELOPED BEFORE
MIDNIGHT IN NW TN...BUT HAS SINCE DIED. A POCKET OF HOTTER
WELL-MIXED AIR WAS LOCATED FROM MIDDLE KY AND TN INTO N AL...WHERE
AFTERNOON DEW POINTS DIPPED INTO THE LOWER-MID 60S. NOTE THE 00Z
KOHX SOUNDING.
SHORT TERM...TODAY AND TONIGHT.
THE QUESTION FOR TODAY IS WHETHER THE FRONT AND THETA-E RIDGE WILL
BE ENOUGH TO AID ISOLD CONVECTION. AND WE ARE HOPING FOR THIS AS IT
MAY BE OUR ONLY CHANCE OF RAIN IN THE NEXT 7-10 DAYS. AT THIS
POINT...THE SURFACE FRONT SHOULD SIT ACROSS SOUTHERN TN INTO THE
SHOALS BY 12-15Z...AND LIKELY PUSH S OF THE TN RIVER BY 18Z. DECENT
N FLOW ALREADY DETECTED JUST ABOVE THE SFC LAYER IS AN INDICATOR
THAT THE FRONT MAY ZOOM PAST THIS MORNING. THE NAM IS FORECASTING
DECENT ML-CAPE ATOP A PRONOUNCED INVERTED-V PROFILE. HOWEVER...THE
MOISTURE LAYER AT THE CCL IS FAIRLY THIN...WITH STRONG DRYING NOTED
ALOFT. IF A STORM CAN DEVELOP...THERE ARE PARAMETERS IN FAVOR OF
DRY MICROBURSTS. THE MPDI/WINDEX VALUES PEAK AROUND 18Z WITH THE
FRONT...WITH VALUES OF 1.4/66 RESPECTIVLY VIA THE NAM12.
HOWEVER...FEEL THE THREAT OF CONVECTION WILL BE HIGHER TO OUR S.
THUS...CHANCES OF ANY STORMS LOOK VERY LOW...AND BASED ON MOS...LESS
THAN 10 PCT. I MAY MAKE A LAST MINUTE CALL ON THIS...BUT FOR NOW I
WILL LEAVE THE ISOLD T IN THE FORECAST. AS WE HAVE SEEN...HEAT
INDICES HAVE BARELY TOUCHED 105F EACH AFTERNOON. HOWEVER...WILL
MAINTAIN THE HEAT ADVISORY FOR TODAY GIVEN THE PERSISTENCE OF THE
HOT TEMPERATURES AND EXPERIMENTAL HEAT STRESS INDEX STILL SHOWING
9.9 FOR TODAY.
LONGER TERM...SATURDAY AND BEYOND...
THE WEAK FRONTAL PASSAGE IS NOT GOING TO PROVIDE MUCH RELIEF...OTHER
THAN DROPPING TEMPS ONLY SLIGHTLY (THATS DEBATABLE AT THIS POINT)
AS NE FLOW BRINGS A NICE SURGE OF DRY ADVECTION. I HAVE RAISED
TEMPS TO AROUND 100F AGAIN IN A FEW SPOTS ON SATURDAY PER LATEST MOS
AND FORECAST SOUNDINGS SHOWING DEEP MIXING. FIRE DANGER WILL ALSO
INCREASE DUE TO A BRISKER FLOW...AND MIN RHS DROPPING BLO 30PCT.
THE HEAT WAVE IS GOING TO BUILD ACROSS MORE OF THE NATION INTO NEXT
WEEK AS THE UPPER RIDGE CENTERS ITSELF OVER THE CENTRAL PLAINS.
THIS RIDGE RE-EXPANDS ACROSS THE SOUTHEAST AGAIN AS WELL. THE GFS
IS SHOWING A BREAKDOWN OF THE RIDGE LATE NEXT WEEK...WITH SOME
ENSEMBLE MEMBERS BUILDING A TROF FURTHER S ALONG THE EASTERN CONUS.
ON THE FLIP SIDE...THE ECMWF BUILDS A 595+DKM RIDGE CENTERED OVER
THE MID SOUTH. 8H TEMPS CLIMBING TO 24-26C...10-8H THICKNESS NEAR
145DAM...BOTH WARMER THAN CURRENTLY...AND SUPPORTIVE OF ANOTHER
STRING OF 100+F TEMPS. 00Z GFS MOS IS FORECASTING 103F AT HSV ON
TUESDAY. IF THE ECMWF IS CORRECT...THIS STRING OF 100+ HEAT COULD
STRETCH THROUGHOUT THE WEEK. NOTE THE LATEST HYDROLOGIC OUTLOOK
(ESFHUN) FROM YESTERDAY MORNING FOR MORE INFORMATION. THE GOOD NEWS
IS THAT SFC DEW POINTS MAY REMAIN RATHER TOLERABLE DURING THE
DAYTIME HOURS...AT LEAST DURING THE EARLY PART OF NEXT WEEK.
