Area forecast discussion, Jul 19, 10:05 AM CDT, 2 hours 58 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1005 AM CDT WED JUL 19 2006

.DISCUSSION...HAVE ISSUED AN UPDATE...MAINLY TO ENHANCE THE SVR TS
RISK FOR TODAY AND TO MAKE A FEW OTHER TWEAKS. OVERALL...IT WILL BE
ANOTHER HOT ONE WITH 97-101 FOR MAX TEMPS. MOISTURE WILL BE SLIGHTLY
HIGHER TODAY AND AS A RESULT THE HEAT INDICES WILL BE HIGHER
(103-108) AREAWIDE. DUE TO THIS...A HEAT ADV WILL REMAIN IN EFFECT.
I WILL TAKE A LOOK AT SOME NEW DATA TO SEE IF MOISTURE WILL BE AS
HIGH ON THU AND IF IT IS...WILL EXTEND THE HEAT ADV ANOTHER DAY.
WILL ISSUE AN UPDATED NPW BETWEEN 11AM AND NOON.

AS FOR THE SVR RISK TODAY...12Z SOUNDING ANALYSIS SUGGESTS A MORE
FAVORABLE ATMOSPHERE THAN YESTERDAY. LAPSE RATES WILL ONCE AGAIN
REMAIN VERY STEEP WITH NEARLY 30 VERTICAL TOTALS. SBCAPE WILL BE
HIGHER TODAY WITH 3000-3400 J/KG ACROSS THE CWA. OUR SOUNDING HAD
850MB DEWPTS AT NEARLY 17C THIS IS SIGNIFICANTLY HIGH AND VERY
SUPPORTIVE OF CONVECTION. THIS HIGH MOISTURE OFF THE SFC WILL LIKELY
REMAIN ALONG AND JUST S OF THE I-20 CORRIDOR MAKING THESE AREAS MORE
FAVORABLE FOR CONV AND THUS SVR STORMS. WE ALSO HAVE FAIRLY STRONG
FLOW IN THE MID LEVELS (20-24KTS) WHICH WILL BE MORE THAN ENOUGH TO
GENERATE ROTATING UPDRAFTS WHICH WILL HELP ORGANIZE STORMS INTO
MULTICELL CLUSTERS. THESE ROTATING UPDRAFTS WILL ALSO LEAD TO
INCREASED HAIL PRODUCTION...LIKE YESTERDAY. AS THE HAIL MELTS...WE
WILL ALSO GENERATE STRONG WINDS AND GUSTS. THIS IS ALSO REFLECTED IN
THE DCAPE THE MODIFIED SOUNDING HAS WHICH IS AROUND 1500 J/KG. THIS
NUMBER IS QUITE SIGNIFICANT...ESPECIALLY WHEN OBSERVED WITH
CONVECTION. THIS COULD RESULT IN MORE INTENSE DOWNBURSTS WITH THE
POTENTIAL FOR 60-75 MPH WINDS.

DUE TO ALL THIS...I HAVE INCREASED THE RISK/WORDING IN THE HWO AND
PROB HAZ GRIDS. DONT BE SURPRISED TO SEE SPC INCREASE TO SLIGHT
RISK TODAY AND IF THINGS CAN DEVELOP LIKE THE POTENTIAL SHOWS...WE
MAY ACTUALLY GET A SVR TS WATCH BOX THIS AFTERNOON.

901 AM CDT WED JUL 19 2006

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL MISSISSIPPI...
NORTHEAST LOUISIANA...AND EXTREME SOUTHEAST ARKANSAS

.DAY ONE...TODAY AND TONIGHT...

...THUNDERSTORMS...
ANOTHER ROUND OF SEVERE THUNDERSTORMS WILL BE POSSIBLE TODAY WITH
A BIT MORE COVERAGE THAN YESTERDAY. THIS WILL RESULT IN SCATTERED
SEVERE STORMS GENERALLY SOUTH AND WEST OF A LINE FROM VICKSBURG
TO RALEIGH TO COLLINS. ELSEWHERE...ISOLATED SEVERE STORMS WILL BE
POSSIBLE. THE MAIN RISK FROM THESE STORMS WILL BE DEADLY
LIGHTING...SMALL HAIL AND DAMAGING WIND GUSTS BETWEEN 60 AND 70
MPH. MOST OF THE ACTIVITY WILL OCCUR BETWEEN 1 AND 8 PM WITH THE
STORMS GENERALLY MOVING TO THE SOUTHWEST.

THE MAIN CULPRIT IN THIS INCREASED SEVERE ACTIVITY WILL BE THE
COMBINATION OF VERY HOT SURFACE CONDITIONS...INCREASING LOW LEVEL
MOISTURE AND COOLER TEMPERATURES ALOFT. THIS IS LEADING TO STEEP
LAPSE RATES AND HIGH LEVELS OF INSTABILITY. THE DISTURBANCE THAT
WILL HELP TRIGGER THE AFTERNOON STORMS WILL BE QUITE POTENT FOR
THIS TIME OF YEAR AND WILL BRING WITH IT FASTER WINDS ALOFT WHICH
WILL HELP ORGANIZE THE STORMS AND ALLOW THEM TO BECOME STRONGER
THAN USUAL.

...SEASONAL THREATS...
EXPECT HEAT INDEX VALUES TO RANGE FROM 103 TO 108 DEGREES TODAY
ACROSS THE ENTIRE ARKLAMISS REGION. DUE TO THIS...A HEAT ADVISORY
HAS BEEN ISSUED FOR WEDNESDAY.

A HEAT INDEX OF 105 IS THE VALUE WHERE THE BODY CAN BEGIN TO
SUCCUMB TO HEAT-RELATED HEALTH PROBLEMS.

PERSONS VENTURING OUTDOORS SHOULD TAKE PRECAUTIONS TO AVOID HEAT
RELATED ILLNESSES.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY...

...DAYS TWO AND THREE...THURSDAY AND FRIDAY...
THE HOT CONDITIONS WILL PERSIST THROUGH FRIDAY WITH THE AREA
REACHING 96 TO 100 DEGREES EACH DAY. PLENTY OF HEAT COMBINED WITH
THE RELATIVE HUMIDITIES WILL LEAD TO HEAT INDEX VALUES FROM 100
TO 107. IF THESE CONDITIONS HOLD...HEAT ADVISORIES WILL LIKELY BE
EXTENDED FOR SOME LOCATIONS UNTIL THE WEEKEND.

...DAYS FOUR THROUGH SEVEN...SATURDAY THROUGH TUESDAY...
A MOIST UNSTABLE AIRMASS WILL BE IN PLACE SATURDAY AS A FRONTAL
BOUNDARY AND UPPER LEVEL DISTURBANCE PLOW SOUTH EASTWARD INTO THE
REGION SETTING OFF SCATTERED THUNDERSTORMS. A FEW OF THESE STORMS
WILL BE ON THE STRONG TO SEVERE SIDE DEPENDING ON THE EXACT
TIMING AND POSITION OF THE FRONT. THE FRONT SHOULD SETTLE NEAR
THE GULF COAST BY EARLY NEXT WEEK. CHECK LATER FORECASTS FOR
ADDITIONAL INFORMATION ON THE SEVERE POTENTIAL.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND
EMERGENCY MANAGEMENT PERSONNEL IN SUPPORT OF SEVERE WEATHER
OPERATIONS WILL LIKELY BE NEEDED FOR TODAY OR AT SOME POINT ON
SATURDAY. OTHERWISE ACTIVATION IS NOT ANTICIPATED THROUGH NEXT
WEDNESDAY.
