GRGWhat 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 Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Feb 23, 10:43 AM CST, 2 hours 54 minutes earlier.
Area forecast discussion, Feb 23, 10:43 AM CST, 2 hours 54 minutes before
AREA FORECAST DISCUSSION...MESOSCALE AND AVIATION UPDATE NATIONAL WEATHER SERVICE JACKSON MS 1043 AM CST WED FEB 23 2005 ...A QUICK UPDATE TO THE TEXT FORECAST WILL BE COMING... .DISCUSSION...MORNING SUBJECTIVE ANALYSIS HAS A STATIONARY FRONT DRAPED ACROSS SOUTH MISSISSIPPI...JUST NORTH OF THE U.S. HIGHWAY 84 CORRIDOR. WATER VAPOR IMAGERY SHOWS A STRONG SHORTWAVE MOVING INTO THE LOWER MISSISSIPPI VALLEY AT LATE MORNING. I EXPECT THIS FEATURE TO AID IN THE DEVELOPMENT OF A SURFACE LOW ALONG THE FRONT...WHICH WILL PROBABLY RESULT IN THE FRONT LIFTING A LITTLE BIT NORTH TOWARD INTERSTATE 20. THE APPROACHING SHORTWAVE TROUGH WILL AID IN THE DESTABILIZATION OF MID-TROPOSPHERIC LAPSE RATES ACROSS THE FORECAST AREA THIS AFTERNOON...ESPECIALLY CONSIDERING THAT CIRRUS IS JUST ABOUT THE ONLY DAMPENING FACTOR TO SOLAR INSOLATION IN MANY PLACES. THE LATEST NUMERICAL MODELS HAVE SOMEWHAT SHIFTED THEIR THINKING FROM YESTERDAYS MORNING RUN...ESPECIALLY WITH THE KINEMATIC FIELDS. WE THINK THAT SOME OF THIS MAY BE DUE TO CONVECTION OCCURRING IN THE MODELS. FOR THE MOST PART...OUR THINKING HASNT REALLY CHANGED FROM YESTERDAY. OUR GRIDDED FORECAST LOOKS TO BE IN DECENT SHAPE...AND NO SIGNIFICANT CHANGES WERE MADE TO THE PACKAGE AT THIS TIME. I WILL UPDATE THE TEXT FORECAST IN ORDER TO REMOVE ANY MORNING WORDING. && .AVIATION...THE BIG PROBLEM FOR THE 1800 UTC TAF PACKAGE WILL BE THE TIMING WITH REGARD TO THE RAIN ENDING. AT THIS POINT...IM NOT TOO CONFIDENT ON THE TIMING AS MY GUT FEELING TELLS ME THAT THERELL PROBABLY BE SOME PRECIPITATION LINGERING BEHIND THE FRONT. FOR NOW...ILL KEEP SOME LIGHT RAIN IN THE TAFS THROUGH 24/1800 UTC AND LET LATER SHIFTS DECIDE. IN GENERAL LOOK FOR MVFR TO IFR CONDITIONS...WITH SOME LOWER CEILINGS AND VISIBILITIES POSSIBLE. && .JAN WATCHES/WARNINGS/ADVISORIES... MS...NONE. LA...NONE. AR...NONE. && BUTTS
