$$What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Memphis, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Feb 17, 7:24 PM CST, 2 hours 58 minutes earlier.
Area forecast discussion, Feb 17, 7:24 PM CST, 2 hours 58 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MEMPHIS TN 724 PM CST TUE FEB 17 2009 .DISCUSSION... FORECAST WAS RECENTLY UPDATED FOR SEVERE THUNDERSTORM WATCH 22. 00Z LZK AND SHV SOUNDINGS SHOW ELEVATED INSTABILITY NEAR 850MB. AN ELEVATED WARM LAYER WAS NOTED AROUND 700MB. 18Z NAM MODEL FORECAST THIS ELEVATED WARM LAYER TO GRADUALLY ERODE THROUGH THE EVENING...ERODING THE CAP TO DEEP CONVECTION. AT THIS TIME... IT APPEARS THAT CONVECTION SHOULD REMAIN ELEVATED... ROOTED IN A LAYER ABOVE THE IMPRESSIVE LOW LEVEL HELICITY. LAPSE RATES SHOULD RUN BETWEEN 6 AND 7 C/KM. GIVEN THE COOL TEMPS BELOW 850 MB... EXPECT HAIL TO THE PRIMARY SEVERE WEATHER THREAT. PWB && .PREV DISCUSSION... /ISSUED 619 PM CST TUE FEB 17 2009/ UPDATE... UPDATED FOR 00Z AVIATION DISCUSSION. DISCUSSION... DEALING WITH POSSIBLE SEVERE THUNDERSTORMS TONIGHT INTO WEDNESDAY MORNING IS THE MAIN FORECAST CONCERN. LATEST MODELS WERE IN GOOD GENERAL AGREEMENT THROUGH FRIDAY...THEN DIVERGED CONSIDERABLY. USED A BLEND OF MODELS WITH NO PREFERENCE FOR ONE OVER ANOTHER. THE BIGGEST CHANGES TO THE FORECAST WAS TO SLIGHTLY LOWER RAIN CHANCES WEDNESDAY MORNING ACROSS NE MS AND INCREASE THEM SLIGHTLY SATURDAY/SATURDAY NIGHT. AT 4 PM CST ACROSS THE FORECAST AREA...CLOUDY AND COOL CONDITIONS WERE OCCURRING WITH SURFACE TEMPERATURES IN THE 40S. SCATTERED LIGHT SHOWERS WERE OVER THE AREA...MAINLY NEAR AND SOUTH OF INTERSTATE 40. A SURFACE LOW WAS OVER KANSAS...MOVING EAST. TONIGHT...EXPECT NUMEROUS SHOWERS AND THUNDERSTORMS TO DEVELOP AS MOISTURE...LIFT...AND INSTABILITY INCREASE. BELIEVE DEVELOPMENT WILL BEGIN BETWEEN 7 PM AND 10 PM...PEAKING AROUND 2 AM...THEN TAPERING OFF TOWARDS SUNRISE AS DRIER AIR MOVES IN FROM THE WEST. WENT WITH VERY HIGH RAIN CHANCES...60 PERCENT AND GREATER...AS MOST...IF NOT ALL...AREAS WILL GET WET. RAINFALL AMOUNTS WILL RANGE FROM 0.10 TO 0.25 INCH OVER NE AR TO 0.50 TO 1 INCH NEAR AND SOUTH OF INTERSTATE 40. WOULD NOT BE SURPRISED IF AN ISOLATED AREA RECEIVED NEAR 2 INCHES OVER WEST TN OR NORTH MS. TEMPERATURES WILL RISE THROUGH THE NIGHT...GETTING INTO THE UPPER 50S AND LOWER 60S BY SUNRISE WEDNESDAY. REGARDING THE SEVERE POTENTIAL TONIGHT...MOST...IF NOT ALL STORMS...WILL REMAIN ELEVATED WITH MUCAPES 500 TO 1300 J/KG FORECAST...WITH THE HIGHEST INSTABILITY OCCURRING LATE TONIGHT. HAIL IS THE MAIN HAZARD...SO KEPT SEVERE AND LARGE HAIL WORDING IN ZONES. SLIGHT RISK APPEARS REASONABLE AND WATCH BOXES MAY BE NEEDED. ACROSS NORTH MS AFTER 4 AM CST...STORMS MAY BE CLOSE FROM BECOMING SURFACE BASED IF SURFACE TEMPERATURES COULD EXCEED 62/63 DEGREES WHICH DAMAGING WINDS OR EVEN A TORNADO COULD OCCUR. RIGHT NOW...THIS APPEARS UNLIKELY. WEDNESDAY STILL APPEARS TO BE AN INTERESTING WEATHER DAY WITH SOME SEVERE STORM POTENTIAL DURING THE MORNING HOURS EAST OF THE MS RIVER AND WINDY/VERY WARM CONDITIONS BY AFTERNOON. REDUCED RAIN CHANCES SLIGHTLY EAST OF THE MS RIVER AS DEEP MOISTURE MAY BE LACKING...PERHAPS NOT ALLOWING FOR MUCH CONVECTION AT ALL...BUT NOT SURE ABOUT THIS AS LOW LEVEL MOISTURE AND INSTABILITY WILL BE ABUNDANT. SEVERE THUNDERSTORMS MAY OCCUR WEDNESDAY MORNING EAST OF THE MS RIVER...PARTICULARLY OVER NE MS...BUT THIS IS DEPENDENT ON THE AMOUNT OF MOISTURE AVAILABLE AND EXACT POSITIONING OF A MID/HIGH LEVEL DRY SLOT/JET MAX. MODERATE INSTABILITY WITH LIFTED INDICES -2 TO -4 IS FORECAST OVER NORTH MS THROUGH EARLY WEDNESDAY AFTERNOON. IF ENOUGH MID LEVEL MOISTURE IS AVAILABLE...THERE IS A POTENTIAL FOR SURFACE BASED CONVECTION MAINLY SOUTHEAST OF A COFFEEVILLE MS TO SAVANNAH TN BETWEEN 6 AM AND 2 PM WEDNESDAY... WHICH THESE STORMS COULD PRODUCE LARGE HAIL...DAMAGING WINDS... AND PERHAPS A TORNADO OR TWO. NOT SURE ABOUT THIS SCENARIO AT THIS TIME. KEPT SLIGHT RISK WORDING IN THE HWO FOR NOW. BY WEDNESDAY AFTERNOON...THE DRY SLOT AND DRIER AIR WILL OVERTAKE THE AREA...ALLOWING FOR CLEARING SKIES AND EXCELLENT MIXING. WINDY CONDITIONS WILL OCCUR WITH WINDS APPROACHING WIND ADVISORY CRITERIA...SUSTAINED 25 MPH OR GREATER WITH GUSTS 40 MPH OR GREATER. THE ENHANCED MIXING WILL ALLOW TEMPERATURES TO TAKE OFF AS WELL...REACHING THE UPPER 60S AND LOWER 70S ACROSS THE ENTIRE AREA. RAIN CHANCES WILL END WITH THE DRIER AIR MOVING IN. WEDNESDAY NIGHT THROUGH FRIDAY...DRY AND COLD CONDITIONS CAN BE EXPECTED. NORTH WINDS 10 TO 20 MPH WILL MAKE FOR BRISK AND MUCH COLDER CONDITIONS WEDNESDAY NIGHT INTO THURSDAY WITH LOWS IN THE LOWER TO MID 30S AND HIGHS IN THE 40S ON THURSDAY...EVEN WITH ABUNDANT SUN. HIGH PRESSURE WILL BE OVERHEAD THURSDAY NIGHT WITH LOWS IN THE 20S. SLIGHTLY WARMER AIR WILL MOVE IN ON FRIDAY WITH SOUTHWEST WINDS DEVELOPING. FRIDAY NIGHT THROUGH SUNDAY MORNING...BIG MODEL DIFFERENCES ARE NOTED WITH THE PASSAGE OF A COLD FRONT...BUT MAY HAVE TO MONITOR FOR POSSIBLE WINTRY WEATHER DURING THIS TIME FRAME. THE LATEST GFS MODEL WAS MOST PROGRESSIVE AND THE OUTLIER...WHILE THE LATEST CANADIAN AND ECMWF MODELS INDICATED A POSSIBLE WINTER STORM OVER THE AREA WITH ALL TYPES OF WINTRY WEATHER. FOR NOW...INCREASED PRECIP CHANCES SLIGHTLY SATURDAY AND SATURDAY NIGHT AND DID NOT MENTION WINTRY WEATHER IN HWO. BELOW NORMAL TEMPERATURES ARE EXPECTED. SUNDAY AFTERNOON THROUGH TUESDAY...GENERALLY DRY CONDITIONS AND BELOW NORMAL TEMPERATURES ARE EXPECTED. MOISTURE AND LOW RAIN CHANCES MAY RETURN BY TUESDAY AS SOUTH WINDS DEVELOP. MBS && .AVIATION... 00Z TAFS MVFR CEILINGS WILL CONTINUE ACROSS ALL TAF SITES AND THEN RAPIDLY LOWER AS SHOWERS AND THUNDERSTORMS DEVELOP AFTER 18/04Z.
